Mathematical Manipulative Models: In Defense of “Beanbag Biology”

Mathematical manipulative models have had a long history of influence in biological research and in secondary school education, but they are frequently neglected in undergraduate biology education. By linking mathematical manipulative models in a four-step process—1) use of physical manipulatives, 2) interactive exploration of computer simulations, 3) derivation of mathematical relationships from core principles, and 4) analysis of real data sets—we demonstrate a process that we have shared in biological faculty development workshops led by staff from the BioQUEST Curriculum Consortium over the past 24 yr. We built this approach based upon a broad survey of literature in mathematical educational research that has convincingly demonstrated the utility of multiple models that involve physical, kinesthetic learning to actual data and interactive simulations. Two projects that use this approach are introduced: The Biological Excel Simulations and Tools in Exploratory, Experiential Mathematics (ESTEEM) Project (http://bioquest.org/esteem) and Numerical Undergraduate Mathematical Biology Education (NUMB3R5 COUNT; http://bioquest.org/numberscount). Examples here emphasize genetics, ecology, population biology, photosynthesis, cancer, and epidemiology. Mathematical manipulative models help learners break through prior fears to develop an appreciation for how mathematical reasoning informs problem solving, inference, and precise communication in biology and enhance the diversity of quantitative biology education.     

Plant Behavior

Plants are a huge and diverse group of organisms ranging from microscopic marine phytoplankton to enormous terrestrial trees. Stunning, and yet some of us take plants for granted. In this plant issue of LSE, WWW.Life Sciences Education focuses on a botanical topic that most people, even biologists, do not think about—plant behavior.Plants are a huge and diverse group of organisms (Figure 1), ranging from microscopic marine phytoplankton (see http://oceandatacenter.ucsc.edu/PhytoGallery/phytolist.html for beautiful images of many species) to enormous terrestrial trees epitomized by the giant sequoia: 300 feet tall, living 3000 years, and weighing as much as 3000 tons (visit the Arkive website, www.arkive.org/giant-sequoia/sequoiadendron-giganteum, for photos and basic information). Stunning, and yet some of us take plants for granted, like a side salad. We may see plants as a focal point during the blooming season or as a nice backdrop for all the interesting things animals do. For this plant issue of CBE—Life Sciences Education, I am going to focus on a botanical topic that most people, even biologists, do not think about—plant behavior.Open in a separate windowFigure 1.Plants are very diverse, ranging in size from microscopic plankton (left, courtesy of University of California–Santa Cruz Ocean Data Center) to the biggest organisms on our planet (right, courtesy Arkive.org).Before digging into plant behavior, let us define what a plant is. All plants evolved from the eukaryotic cell that acquired a photosynthetic cyanobacterium as an endosymbiont ∼1.6 billion years ago. This event gave the lineage its defining trait of being a eukaryote that can directly harvest sunlight for energy. The cyanobacteria had been photosynthesizing on their own for a long time already, but this new “plant cell” gave rise to a huge and diverse line of unicellular and multicellular species. Genome sequences have shed light on the birth and evolution of plants, and John Bowman and colleagues published an excellent review titled “Green Genes” several years ago in Cell (www.sciencedirect.com/science/article/pii/S0092867407004618#; Bowman et al., 2007 ). The article has concise information on the origin and evolution of plant groups, including helpful graphics (Figure 2). Of course, plants were classified and subdivided long before DNA analysis was possible. The Encyclopedia of Earth (EOE) is a good website for exploring biological diversity and has an article on plants (www.eoearth.org/view/article/155261) that lays out the major plant groups and their characteristics. It states that there are more than 400,000 described species, a fraction of the estimated total number.Open in a separate windowFigure 2.Genomic analysis has illuminated the relationship among the many species of plants, as illustrated in this phylogeny of three major plant groups from Bowman et al. (2007 , p. 129).The venerable Kew Gardens has an excellent website (Figure 3) that includes extensive pages under the tab Science and Conservation (www.kew.org/science-conservation). It is a beautifully organized website for exploring plant diversity and burrowing into the science of plants, and includes an excellent blog. Ever wonder how many different kinds of flowers there are? You can find out by visiting their feature titled, “How Many Flowering Plants Are There in the World?” There is an interesting video feature on coffee, which describes how only two species out of more than a hundred have come to dominate coffee production for drinking. As the monoculture in Ireland led to the potato blight, a lack of genetic diversity in today''s coffee plants is threatening the world''s coffee supply with the onset of climate change. The possibility of life without coffee is a call to action if ever I have heard one.Open in a separate windowFigure 3.Kew Gardens has a large and informative website that should appeal to gardeners and flower lovers, as well as more serious botanists and ecologists.Classification of plants is challenging for students and teachers alike. Perhaps understandable, given that plants constitute an entire kingdom of life. For an overview, have students read the EOE article as well as the Bowman Cell article to appreciate the enormity and diversity of the organisms we call plants. The EOE article is reproduced on the Encyclopedia of Life website (http://eol.org/info/449), an excellent context for further exploration of diverse plant species. As we probe the topic of plant behavior, the examples will be drawn from the vascular plants that include the many familiar plants commonly called trees, shrubs, flowers, vegetables, and weeds.Plants do respond to changes in their environment, but is it fruitful or scientifically valid to say that they have behavior? They lack muscles and nerves, do not have mouths or digestive systems, and are often literally rooted in place. A growing number of plant biologists have embraced the term behavior, as demonstrated by the journal devoted to the subject, Plant Behavior. Their resources page (www.plantbehavior.org/resources.html) is a good place to get oriented to the field.As in so many things, Darwin anticipated important questions concerning the movement of plants, despite the difficulties in observing plant behavior, and in 1880 he published The Power of Movement in Plants. The Darwin Correspondence Project website has a good treatment of Darwin''s work on plants, with interesting anecdotes relating to how he collaborated with his son Francis on this work late in his career (www.darwinproject.ac.uk/power-of-movement-in-plants). You can download Chapter 9 of the book and some of the correspondence between Darwin and his son. The entire book is available at http://darwin-online.org.uk/content/frameset?itemID=F1325&viewtype=text&pageseq=1, or in various e-reader formats at the Project Gutenberg website (http://www.gutenberg.org/ebooks/5605). The PBS NOVA website, has a feature covering several of Darwin''s “predictions,” including one in which he noted the importance of plant and animal interactions. He famously predicted that a Madagascar orchid (Angraecum sesquipedale), which has a long narrow passage to its nectar stash, must have a long-tongued pollinator. In 1903, biologists identified the giant hawkmoth, with a 12-inch-long proboscis, as the pollinator predicted by Darwin (www.pbs.org/wgbh/nova/id/pred-nf.html).Darwin recognized that plants mostly do things on a timescale that is hard for us to observe, so he devised clever ways to record their movements. Placing a plant behind a pane of glass, he marked the plant''s position on the glass over time using a stationary reference grid placed behind the plant. Darwin transferred the drawing to a sheet of paper before cleaning the glass for the next experiment (Figure 4). By varying the distance between the plant, the reference points, and the glass, he magnified apparent distances to detect even small plant movements over periods as short as minutes. High-definition time-lapse photography and other modern techniques have extended Darwin''s observations in some compelling directions.Open in a separate windowFigure 4.One of Darwin''s drawings that can be found on the Darwin Correspondence Project Web pages devoted to his book The Power of Movement in Plants. For this figure, the position of the cotyledons of a Brassica was marked on a glass plate about every 30 min over a period of more than 10 h.A recent episode of the PBS Nature series, “What Plants Talk About,” epitomizes the increased interest in plant behavior and, unfortunately, some of the hyperbole associated with the field. The time-lapse video sequences and associated science are fascinating, and the entire program can be viewed on the PBS website at http://video.pbs.org/video/2338524490. The home page for the program (Figure 5; www.pbs.org/wnet/nature/episodes/what-plants-talk-about/introduction/8228) has two short video clips that are interesting. The video titled “Dodder Vine Sniffs Out Its Prey” is nicely filmed and features some interesting experiments involving plant signaling. It might be instructive to ask students to respond to the vocabulary used in the narration, which unfortunately tries to impart intent and mindfulness to the plant''s activities, and to make sensible experimental results somehow seem shocking. The “Plant Self-Defense” video is a compelling “poison pill” story that needs no narrative embellishment. A plant responds to caterpillars feeding on it by producing a substance that tags them for increased attention from predators. Increased predation reduces the number of caterpillars feeding on the plants. The story offers a remarkable series of complex interactions and evolutionary adaptations. Another documentary, In the Mind of Plants (www.youtube.com/watch?v=HU859ziUoPc), was originally produced in French. Perhaps some experimental interpretations were mangled in translation, but the camera work is consistently excellent.Open in a separate windowFigure 5.The Nature pages of the PBS website have video clips and a short article, as well as the entire hour-long program “What Plants Talk About.” The program features fantastic camera work and solid science, but some questionable narration.Skepticism is part and parcel of scientific thinking, but particular caution may be warranted in the field of plant behavior because of the 1970s book and documentary called The Secret Life of Plants (www.youtube.com/watch?v=sGl4btrsiHk). The Secret Life of Plants was a sensation at the time and was largely responsible for the persistent myths that talking to your plants makes them healthier, that plants have auras, and that plants grow better when played classical music rather than rock. While the program woke people up to the notion that plants indeed do fascinating things, the conclusions based on bad science or no science at all were in the end more destructive than helpful to this aspect of plant science. Michael Pollan, author of The Botany of Desire and other excellent plant books, addresses some of the controversy that dogs the field of plant behavior in an interview on the public radio program Science Friday (http://sciencefriday.com/segment/01/03/2014/can-plants-think.html). His article “The Intelligent Plant” in the New Yorker (www.newyorker.com/reporting/2013/12/23/131223fa_fact_pollan?currentPage=all), covers similar ground.The excellently understated Plants in Motion website (http://plantsinmotion.bio.indiana.edu/plantmotion) is a welcome antidote to some of the filmic excesses. The site features dozens of low-definition, time-lapse videos of plants moving, accompanied by straightforward explanations of the experimental conditions and some background on the plants. The lack of narration conveys a refreshing cinema verité quality, and you can choose your own music to play while you watch. Highlights include corn shoots growing toward a light bulb, the rapid response of a mimosa plant to a flame, vines twining, and pumpkins plumping at night. You may have driven past a field of sunflowers and heard the remark that the heads follow the sun, but that is a partial truth. The young buds of the early plants do track the sun, but once they bloom, the tall plants stiffen and every head in the field permanently faces … east! The creators of Plants in Motion curated an exhibit at the Chicago Botanic Gardens called sLowlife (Figure 6). The accompanying video and “essay” (http://plantsinmotion.bio.indiana.edu/usbg/toc.htm) are excellent, featuring many interesting aspects of plant biology.Open in a separate windowFigure 6.sLowlife is an evocative multimedia essay designed to accompany an exhibit installed at the Chicago Botanic Gardens. It features text and video that reveal interesting aspects of plant biology.High-definition time-lapse photography is far from the only tool available to reveal hard-to-observe activities of plants. Greg Asner and colleagues at the Carnegie Airborne Observatory are using informatics to study the dynamic lives of plants at the community ecology level. The Airborne Observatory uses several impressive computer- and laser-enabled techniques (http://cao.stanford.edu/?page=cao_systems) to scan the landscape at the resolution of single leaves on trees and in modalities that can yield information at the molecular level. These techniques can yield insights into how forests respond to heat or water stress or the introduction of a new species. The site has a gallery of projects that are best started at this page: http://cao.stanford.edu/?page=research&pag=5. Here, they are documenting the effect of the Amazon megadrought on the rain forest. The very simple navigation at the top right consists of 15 numbered squares for the different projects. Each project is worth paging through to understand how versatile these aerial-mapping techniques are. They also have six buttons of video pages (http://cao.stanford.edu/?page=videos) that give you a feel for what it might be like to be in the air while collecting the data (Figure 7).Open in a separate windowFigure 7.The Carnegie Airborne Observatory is a flying lab that can collect real-time aerial data on forests at resolutions smaller than a single leaf on a tree.If this Feature seems to have been too conservative about whether plants have behavior, visit the LINV blog (www.linv.org/blog/category/plant-behavior) of the International Laboratory for Plant Neurobiology. The term “plant neurobiology” may be going too far, but the website presents some interesting science. Another fascinating dimension of plant “behavior” is seed dispersal, from seeds that can burrow, to seeds that “fly,” to seeds that are shot like bullets. A couple of websites have some good information and photos of the myriad designs that have evolved to take advantage of air currents for seed dispersal; see http://waynesword.palomar.edu/plfeb99.htm and http://theseedsite.co.uk/sdwind.html. The previously mentioned PBS Nature series also produced a program on seeds, “The Seedy Side of Plants,” which you can view at www.pbs.org/wnet/nature/episodes/the-seedy-side-of-plants/introduction/1268. ChloroFilms, a worldwide competition for plant videos, is now in its fourth season, with some really good videos (www.chlorofilms.org). If you love plants, work with plants, or have insights into plant biology, you should consider submitting a video!     

Review of: National Institutes of Health Curriculum Supplements: Human Genetic Variation and Cell Biology and Cancer,by Biological Sciences Curriculum Study and Videodiscovery; 1999; http://science.education.nih.gov/customers.nsf/highschool.htm

The National Institutes of Health publishes a series of science curriculum supplements for K–12 education that are available from their Web site free of charge (http://science.education.nih.gov/supplements). In this feature, we review two of the high school supplements, Human Genetic Variation and Cell Biology and Cancer. Overall, we find that they are both excellent resources that engage students in learning science content while emphasizing the impact of scientific breakthroughs on personal and public health. In this review, we highlight the many strong features of the curricula and point out instances in which teachers may wish to seek out supplemental, updated information.     

Do we give them a fair chance? Attrition among first-year tertiary students

International research suggests that government policy, institutional culture and learner characteristics influence the attrition rate of first-year tertiary education students. These variables were investigated in relation to a cohort of 21 New Zealand students who failed a core literacy paper. The research utilised questionnaires, interviews with staff and students and observations around a series of workshops designed to review the literacy course. Results align with international findings, but also differ because of site-specific institutional, and student socio-cultural factors. The workshops improved students’ course content knowledge, but did not address deep-seated, literacy and culturally-based impediments that contribute to attrition. Principles of social justice and social contract theory described by Rawls (1958 Rawls, J. 1958. Justice as fairness. Philosophical Review, 67: 164–193. [Crossref], [Web of Science ®] , [Google Scholar]) and Sen (2009 Sen, A. 2009. The idea of justice, Cambridge, MA: Harvard University Press and London: Allen Lane. [Crossref] , [Google Scholar]) are used to critique policy and pedagogical and learner characteristics. Based on this critique, the research concluded that some aspects of policy and institutional, cultural and student behaviour were unjust.     

Leading professional learning in an Australian secondary school through school‐university partnerships

As the limitations of one‐off and disconnected professional learning programs for teachers are recognised, there is widespread interest in building learning communities and professional learning teams within schools. When considering how to build local learning communities, school and university partnerships are seen as offering rich possibilities for transformative professional action. Set in the context of the international agenda of “Education For All” (UNESCO, 2005 UNESCO. (2005). Education for all: Global monitoring project. Retrieved January 8, 2007, from http://portal.unesco.org/education/en/ev.php‐URL_ID=36004&URL_DO=DO_TOPIC&URL_SECTION=201.html (http://portal.unesco.org/education/en/ev.php-URL_ID=36004&URL_DO=DO_TOPIC&URL_SECTION=201.html)  [Google Scholar]) a model of sustained on‐going professional learning, developed in one large secondary school in Australia, is analysed. The social practices that generate action and participation for partnership members are then scrutinised for the legitimacy of school‐university partnerships and the contribution to enhancing teacher learning.     

Support and Challenge in Mentoring: A CaseStudy of Beginning Elementary Teachers and Their Mentors

In a recent Journal of Early Childhood Teacher Education article, the author reported on a single case of a successful mentor–beginning teacher pairing that was derived from a larger qualitative study (Certo, 2005 Certo, J. 2005. Support, challenge, and the two-way street: Perceptions of a beginning second grade teacher and her quality mentor. Journal of Early Childhood Teacher Education, 26(1): 3–21. [CSA][Taylor & Francis Online] , [Google Scholar]). The purpose of this article is to report findings from that larger investigation. Three Virginia elementary 1^st-year teachers and their mentors were interviewed in September, December, and February. Beginning teachers also kept journals of reflections about challenges in 1^st-year teaching and the presence, nature, and impact of mentoring activities. Perceptions of mentor activities and the perceived impact on beginning teachers’ thinking and professional development are described using Daloz’s support and challenge model (1988) Daloz, L. 1988. The story of Gladys who refused to grow: A morality tale for mentors. Lifelong Learning, 11(4): 4–7. [CSA] [Google Scholar]. Mentors provided a balance of support and challenge activities, and beginning teachers reported being impacted by their mentors in numerous ways, from classroom management to adoption of new instructional approaches. These cases may be useful to practitioners as models of effective practice.     

Teaching Bioinformatics and Neuroinformatics by Using Free Web-based Tools

This completely computer-based module''s purpose is to introduce students to bioinformatics resources. We present an easy-to-adopt module that weaves together several important bioinformatic tools so students can grasp how these tools are used in answering research questions. Students integrate information gathered from websites dealing with anatomy (Mouse Brain Library), quantitative trait locus analysis (WebQTL from GeneNetwork), bioinformatics and gene expression analyses (University of California, Santa Cruz Genome Browser, National Center for Biotechnology Information''s Entrez Gene, and the Allen Brain Atlas), and information resources (PubMed). Instructors can use these various websites in concert to teach genetics from the phenotypic level to the molecular level, aspects of neuroanatomy and histology, statistics, quantitative trait locus analysis, and molecular biology (including in situ hybridization and microarray analysis), and to introduce bioinformatic resources. Students use these resources to discover 1) the region(s) of chromosome(s) influencing the phenotypic trait, 2) a list of candidate genes—narrowed by expression data, 3) the in situ pattern of a given gene in the region of interest, 4) the nucleotide sequence of the candidate gene, and 5) articles describing the gene. Teaching materials such as a detailed student/instructor''s manual, PowerPoints, sample exams, and links to free Web resources can be found at http://mdcune.psych.ucla.edu/modules/bioinformatics.     

Exploration of direct and indirect associations of system-level policy-amenable variables with reading literacy performance

As expectations of the economic impact of educational attainment are soaring (Hanushek & Woessmann, 2009 Hanushek E. A., & Woessmann, L. (2009). Do better schools lead to more growth? Cognitive skills, economic outcomes, and causation (NBER Working Paper, No. 14633). Cambridge, MA: National Bureau of Economic Research.[Crossref] , [Google Scholar]) and conjectures about successful national educational reforms (Mourshed, Chijioke, & Barber, 2010 Mourshed, M., Chijioke, C., & Barber, M. (2010). How the world's most improved school systems keep getting better. Retrieved from http://www.mckinsey.com/client_service/social_sector/latest_thinking/worlds_most_improved_schools[Crossref] , [Google Scholar]) are welcomed by educational policy-makers in many countries, a careful assessment of the empirical evidence for these kinds of claims is needed. In this article, we present a methodology that was applied to an international data set. A multi-level model of education was used to present a hypothetical scenario, indicated as the “implementation scenario”. The scenario was tested on the Programme for International Student Assessment (PISA) 2009 data set by means of multi-level structural equation modelling. Although we find some evidence for direct effects and some support for straightforward implementation, the overall impact of malleable conditions at the system and school level appears disappointingly small. A theoretical strand of literature that would account for “limited malleability” is referred to in discussing these results.     

Comparison of Direct Instruction and Discrete Trial Teaching on the Curriculum-based Assessment of Language Performance of Students with Autism

There is limited research demonstrating direct instruction (DI) as an effective language intervention for students with autism spectrum disorders (ASD) and developmental disabilities (DD). Existing research has shown that instruction using partial implementation of DI programs resulted in student learning (Ganz, 2007 Ganz, M. L. (2007). The lifetime distribution of the incremental societal costs of autism. Archives of Pediatrics & Adolescent Medicine, 161, 343&349.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and instruction using whole lessons resulted in positive instructional effects for students with ASD and DD (Ganz, 2007 Ganz, M. L. (2007). The lifetime distribution of the incremental societal costs of autism. Archives of Pediatrics & Adolescent Medicine, 161, 343&349.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). However, it is not known whether DI is more effective than other language interventions. The purpose of this study was to compare DI to an established intervention, discrete trial teaching. Thirteen students with ASD or participated in the study and data were collected using curriculum-based assessment. An independent samples t-test indicated that there was a statistically significant difference in student performance for the group who received DI. Results and their implications will be discussed.     

Equivalent Structural Equation Models: A Challenge and Responsibility

Relevant aspects of the example provided by Raykov and Marcoulides (2001) Raykov, T. and Marcoulides, G. A. 2001. Can there be infinitely many models equivalent to a given covariance structure model?. Structural Equation Modeling, 8: 142–149. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] are emphasized, specifically the distinctiveness of infinitely many members of its sequence of equivalent structural equation models. This emphasis appears to be needed in light of recent statements by Markus (2002) Markus, K. A. 2002. Statistical equivalence, semantic equivalence, eliminative induction and the Raykov–Marcoulides proof of infinite equivalence. Structural Equation Modeling, 9: 503–522. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], whose intended counterexamples do not present a disconfirmation of any of the developments of Raykov and Marcoulides (2001) Raykov, T. and Marcoulides, G. A. 2001. Can there be infinitely many models equivalent to a given covariance structure model?. Structural Equation Modeling, 8: 142–149. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]. Issues pertaining to differentiation between equivalent models are also discussed.     

Conducting the “Business of Teaching”: Expectations of Non-instructional Tasks of Beginning STEM Teachers

Abstract

Much debate centers on the most necessary elements of teacher preparation programs, with many focusing on practice of core instructional tasks (Forzani 2014 Forzani, F. M. 2014. Understanding “Core Practices” and “Practice-Based” teacher education learning from the past. Journal of Teacher Education 65 (4):357–68. doi: 10.1177/0022487114533800.[Crossref], [Web of Science ®] , [Google Scholar]; Kennedy 2016 Kennedy, M. 2016. Parsing the practice of teaching. Journal of Teacher Education 67 (1):6–17. doi: 10.1177/0022487115614617.[Crossref], [Web of Science ®] , [Google Scholar]), which may be diluted in alternative preparation programs (Forzani 2014 Forzani, F. M. 2014. Understanding “Core Practices” and “Practice-Based” teacher education learning from the past. Journal of Teacher Education 65 (4):357–68. doi: 10.1177/0022487114533800.[Crossref], [Web of Science ®] , [Google Scholar]). Teachers prepared in alternative programs tend to have greater difficulties with classroom management, instructional planning, and differentiated instruction (Darling-Hammond 2009 Darling-Hammond, L. 2009. Educational opportunity and alternative certification: New evidence and new questions. Policy Brief (1). Stanford, CA: Stanford Center for Opportunity Policy in Education. [Google Scholar]; Wilson 2011 Wilson, S. 2011. Effective STEM teacher preparation, induction, and professional development. In National Research Council’s Workshop on Successful STEM Education in K–12 Schools. Washington, DC. http://sites.nationalacademies.org/dbasse/bose/dbasse_080128#.UgEMEFPkDDn. [Google Scholar]); however, few studies have examined alternatively prepared STEM teachers’ beliefs and expectations about teaching and learning (Tigchelaar et al. 2010 Tigchelaar, A., N. Brouwer, and J. Vermunt. 2010. Tailor-made: Towards a pedagogy for educating second-career teachers. Educational Research Review 5 (2):164–83.[Crossref], [Web of Science ®] , [Google Scholar]; Good et al. 2006 Good, T., M. McCaslin, H. Tsang, J. Zhang, C. Wiley, A. Rabidue Bozack, and W. Hester. 2006. How well do 1st-year teachers teach: Does type of preparation make a difference? Journal of Teacher Education 57 (4):410–30.[Crossref], [Web of Science ®] , [Google Scholar]), and fewer still have examined their beliefs about non-instructional responsibilities associated with the profession (LeTendre et al. 2001 LeTendre, G.K., D.P. Baker, M. Akiba, B. Goesling, and A. Wiseman. 2001. Teachers' work: Institutional isomorphism and cultural variation in the U.S., Germany, and Japan. Educational Researcher 30 (6):3–15. doi: 10.3102/0013189X030006003.[Crossref] , [Google Scholar]; Ovando 2001 Ovando, M. N. 2001. Teachers' perceptions of a learner-centered teacher evaluation system. Journal of Personnel Evaluation in Education 15 (3):213–231. [Google Scholar]; Scriven 1994 Scriven, M. 1994. Duties of the teacher. Journal of Personnel Evaluation in Education 8 (2):151–84. doi: 10.1007/BF00972261.[Crossref] , [Google Scholar]). This inquiry examines the expectations of a cohort of STEM practitioners transitioning into STEM teaching positions from an abbreviated alternative certification program; during their first year of teaching and concurrent final internship, the paid interns exhibited heightened emotional responses (i.e. crying, not eating, not sleeping) documented by university supervisors. Researchers utilized Self-Discrepancy Theory (Higgins 1987 Higgins, E. T. 1987. Self-discrepancy: A theory relating self and affect. Psychological Review 94 (3):319–40.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) to provide an understanding of how expectations can produce negative affect, such as anxiety or depression. Findings suggest this cohort of paid interns had expectations about both personal and non-instructional time, planning, school resources, and legal responsibilities incongruent with the realities of the job. Researchers call for further research on STEM practitioners’ beliefs and expectations of non-instructional tasks as they transition from accelerated M.A.T. programs into teaching.     

The Merits and Demerits of Pleasure in Kinesiology

What role should pleasure play in kinesiology? Although pleasure is an important concept in kinesiology, the strengths, weaknesses, and dangers of this concept have not been properly clarified. Douglas Booth and Richard Pringle have both recently scolded kinesiologists over the issue of pleasure in kinesiology with decidedly mixed results. They insist that the importance of pleasure has been neglected, and that the role that human culture plays in properly understanding pleasure in kinesiology, has been underestimated. Booth (2009) Booth, D. 2009. Pleasure and physical education philosophy. Quest, 61(2): 133–153. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] argues that “puritanical” prohibitions have made pleasure suspect. Pringle (2010) Pringle, R. 2010. The educative value of positive movement affects. Quest, 62(2): 119–134. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] argues that kinesiologists must remember that “many students are not currently gaining a love for movement in their [physical education] experiences” (p. 130). Each scholar's suspicion of traditional distinctions between “good and bad physical pleasures” (Booth, 2009 Booth, D. 2009. Pleasure and physical education philosophy. Quest, 61(2): 133–153. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], p. 148) results in an untenable commitment to pleasure as an intrinsic good. In short, their views are hedonistic. Although Booth and Pringle are right that pleasure is good, it is not an end in itself.     

Learning through boundary‐crossing: further education lecturers learning in both the university and workplace

This paper reports on a research project that sought to gain a deeper understanding of the contribution that universities make to the professional learning of teachers. The particular case studied was a group of learners who were engaged in an in‐service teacher education course for further education (FE) whilst also working as lecturers in FE colleges in Scotland. The paper develops the narrative of learning across boundaries (Saunders 2006 Saunders, M. 2006. From ‘organisms’ to ‘boundaries’: The uneven development of theory narratives in education, learning and work connections.. Journal of Education and Work, 19: 1–27. [Taylor & Francis Online] [Google Scholar]) drawing on the work of Engeström (1987 Engeström, Y. 1987. Learning by expanding: An activity‐theoretical approach to developmental research, Helsinki: Orienta‐Konsultit. [Crossref] [Google Scholar], 2001 Engeström, Y. 2001. Expansive learning at work: Toward an activity theoretical reconceptualisation.. Journal of Education and Work, 14: 133–56. [Taylor & Francis Online] [Google Scholar]). The claim made is that the learning that takes place across the boundary of the workplace and university has the possibility of helping learners to resolve issues that the workplace alone does not provide them with the resources to resolve.

Cet article fait un compte‐rendu sur un projet de recherche dont le but était d'approfondir les connaissances sur la contribution des universités à la formation professionelle des professeurs. Le cas particulier qu'on a étudié était un groupe d'apprenants qui ont suivi un cours de formation d'enseignement professionnelle en travaillent commme professeurs dans des centres d'enseignement professionnel. L'article se déroule la narration d'apprentissage à travers les frontières (Saunders 2006 Saunders, M. 2006. From ‘organisms’ to ‘boundaries’: The uneven development of theory narratives in education, learning and work connections.. Journal of Education and Work, 19: 1–27. [Taylor & Francis Online] [Google Scholar]) et d'après les recherches d'Engstrom (1987 Engeström, Y. 1987. Learning by expanding: An activity‐theoretical approach to developmental research, Helsinki: Orienta‐Konsultit. [Crossref] [Google Scholar], 2001 Engeström, Y. 2001. Expansive learning at work: Toward an activity theoretical reconceptualisation.. Journal of Education and Work, 14: 133–56. [Taylor & Francis Online] [Google Scholar]). On prétend que la connaissance qu'on a produit à travers des frontières du lieu de travail et de l'université pourrait aider les étudiants à résoudre des problèmes qu'ils ne pourraient pas résoudre en travaillant seulement.

Este trabajo presenta un proyecto de investigación que ha buscado una comprensión más detallada sobre la contribución aportada por la universidad al aprendizaje profesional del profesorado. El trabajo ha estudiado un grupo de alumnos que participaron en un curso avanzado de educación mientras trabajaban como profesores en institutos de enseñanza en Escocia. El estudio desarrolla la temática del aprendizaje a través de límites (Saunders 2006 Saunders, M. 2006. From ‘organisms’ to ‘boundaries’: The uneven development of theory narratives in education, learning and work connections.. Journal of Education and Work, 19: 1–27. [Taylor & Francis Online] [Google Scholar]) inspirándose en el trabajo de Engeström (1987 Engeström, Y. 1987. Learning by expanding: An activity‐theoretical approach to developmental research, Helsinki: Orienta‐Konsultit. [Crossref] [Google Scholar], 2001 Engeström, Y. 2001. Expansive learning at work: Toward an activity theoretical reconceptualisation.. Journal of Education and Work, 14: 133–56. [Taylor & Francis Online] [Google Scholar]). La reivindicación hecha es que el aprendizaje que tiene lugar a través del límite del lugar de trabajo y la universidad tiene la posibilidad de ayudar a los alumnos en resolver asuntos en que el lugar de trabajo por si solo no puede proveerles con los recursos para su resolución.

Dieser Artikel berichtet die Resultate eines Forschungsprojektes, dass zu verstehen versuchte, was Universitäten zum professionellen Lernen von Lehrern beitragen. Ein Gruppe von Studenten wurder untersucht, die in Schottland an Berufsschulen unterrichteten und gleichzeitig an einem Weiterbildungskurs fuer Lehrkräfte an der Universität teilnahmen. Der Artikel ist auf der Arbeit von Engström basiert und konzentriert sich auf Lernen, das über Grenzen hinweg stattfindet (Saunders) (in unserem Fall Arbeitsplatz und Universität). Wir behaupten, dass das solches Lernen grössere Moeglichkeiten bietet, Probleme zu lösen, als Lernen, welches nur am Arbeitsplatz stattfindet.     

Do unto others or not: equity in feedback for undergraduates

This article argues that the mechanisms and research culture that support university academics when writing articles for publication in an iterative feedback cycle, and which are within the tenets of good pedagogic principles of formative assessment and feedback (Sadler, 1989 Sadler, D. R. 1989. Formative assessment and the design of instructional systems. Instructional Science, 18: 145–165. [Crossref], [Web of Science ®] [Google Scholar]), are often missing to support undergraduate students in their learning. The reasons for this are mainly historical. Generally, this process is only available in universities at postgraduate level, as undergraduates tend not to be included in this type of learning culture. This is exacerbated because of the exclusion of undergraduates from assessment processes, which would help them to understand and assimilate the feedback on their work. Data collected from validated documentation of undergraduate programmes at a new English university were used to attempt to quantify possible feedback available to students and their access to assessment.     

Developing Peer Mentoring Support for TAFE Students Entering 1st-Year University Early Childhood Studies

At Queensland University of Technology (QUT, Australia), in the Bachelor of Education (BEd) (Early Childhood) (EC), Technical and Further Education (TAFE) students with a diploma enroll with advanced standing (1 year’s credit). These students share many challenges faced by 1st-year university students—workload, technology, academic orientation, and application. They also experience feelings of isolation and uncertainty in dealing with the “university culture” (Cantwell & Scevak, 2004 Cantwell, R. H. and Scevak, J. J. 2004. Engaging university learning: The experiences of students entering university via recognition of prior industrial experience. Higher Education Research and Development, 23(2): 131–145. [CSA][CROSSREF][Taylor & Francis Online] , [Google Scholar]; Dickson, 2000 Dickson, J. (2000, July). TAFE child care graduates beginning a university teaching degree. Paper presented at the Australian Association of the Research in Education, Sydney, Australia. www.aare.edu.au/00pap/dic00164.htm (Accessed: 5 March 2005).  [Google Scholar]). Often, they do not perform as well academically and their attrition rates are higher than those for 1st-year students and the remainder of the BEd (EC) cohort (Strategic Information & Analysis Division of Finance, Resources, Planning, QUT, 2003). This project addresses issues facing these students in their transition to university by developing an integrated and contextualized mentoring program designed specifically for their needs. Nine early childhood 3rd- and 4th-year students were enlisted as mentors to groups of approximately six transition TAFE students. In this paper we discuss the dynamics of the mentoring scheme and future directions for mentoring projects within the BEd (EC).     

THREE STRATEGIES FOR DELIVERING CONTINUING MEDICAL EDUCATION IN GERIATRICS TO GENERAL PRACTITIONERS

General practitioners (GPs) need advanced skills in geriatric assessment to be competent to treat the increasing number of elderly patients. Continuing medical education in geriatrics for GPs is heterogeneous, and not assessed for effectiveness. In this study we compared the educational effects of three geriatric post-graduate training methods on GPs. GPs in the health district of the Nijmegen University Medical Centre (The Netherlands) were offered a variety of training options in geriatric assessment: (1) a formal one-day teacher centered conference (TCC), (2) an interactive GP-centered day of workshops (GCW), and (3) participation in a project of knowledge translation, linked to a research project of geriatric intermediate care (GKT). Pre-post measures were taken of the attitudes of GPs towards the elderly (Aging Semantic Differential, 1969), attitudes towards geriatric patients (Maxwell & Sullivan, 1980 Maxwell, A. J. and Sullivan, N. 1980. Attitudes toward the geriatric patient among family practice residents. Journal of the American Geriatric Society, 2(8): 341–345.  [Google Scholar]; Rosencranz & McNevin, 1969 Rosencranz, H. A. and McNevin, T. E. 1969. A factor analysis of attitudes towards the aged. Gerontologist, 9: 55–59. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and geriatric competencies (Robinson, Barry, Renick, et al., 2001 Robinson, B. E., Barry, P. P., Renick, N., Bergen, M. R. and Stratos, G. A. 2001. Physician confidence and interest in learning more about common geriatric topics: A needs assessment. Journal of the American Geriatric Society, 49: 963–967. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). After training, neither the attitudes towards the elderly nor geriatric patients changed in any of the three groups. The TCC did not show a significant change in perceived competencies, while the GCW and GKT group improved. A formal large group conference is ineffective in improving GPs' geriatric assessment skills, while small interactive workshops and participation in a project of knowledge translation are equally effective. None of the three training methods improved or worsened attitudes toward the elderly in general or the geriatric patients in particular.     

A quantitative assessment of classroom teaching and learning in engineering education

All stakeholders are aware of the importance of measuring performance in higher education at the university/college level. Generally the performance indicators used for this purpose have focused on graduation rates and/or final examination scores, rather than the performance-enabling processes. Further, the most commonly used method for knowledge transfer is the traditional classroom teaching, which should be tracked/monitored continuously during its delivery process. It can help in the detection and correction of existing and impending problems, if any, in the teaching and learning processes. Further, the students’ attitude towards learning, that is, their readiness/willingness and interest should also be taken into consideration while measuring the performance of classroom teaching.

In the present paper, the model for measuring classroom performance illustrated by Grygoryev and Karapertrovic (2005) Grygoryev, K. and Karapetrovic, S. 2005. Tracking classroom teaching and learning: an SPC application. Quality engineering, 17: 405–418. [Taylor & Francis Online] [Google Scholar] is used to measure the performance of under-graduate Engineering students in two BTech. (Mechanical) courses, namely, fluid mechaincs (FM) and experimental methods and analysis (EMA). Classroom assessment techniques (CATs) along with the statistical process control (SPC) have been used to analyse the learning performance. Further, the data for student's readiness and interest factors are collected and their positive influences on knowledge gain are established.
