An elemental model of retrospective revaluation without within-compound associations

When retrospective revaluation phenomena (e.g., unovershadowing: AB+, then A?, then test B) were discovered, simple elemental models were at a disadvantage because they could not explain such phenomena. Extensions of these models and novel models appealed to within-compound associations to accommodate these new data. Here, we present an elemental, neural network model of conditioning that explains retrospective revaluation apart from within-compound associations. In the model, previously paired stimuli (say, A and B, after AB+) come to activate similar ensembles of neurons, so that revaluation of one stimulus (A?) has the opposite effect on the other stimulus (B) through changes (decreases) in the strength of the inhibitory connections between neurons activated by B. The ventral striatum is discussed as a possible home for the structure and function of the present model.     

Effect of combined carbohydrate-protein ingestion on markers of recovery after simulated rugby union match-play

In this study, we investigated the effect of ingesting carbohydrate alone or carbohydrate with protein on functional and metabolic markers of recovery from a rugby union-specific shuttle running protocol. On three occasions, at least one week apart in a counterbalanced order, nine experienced male rugby union forwards ingested placebo, carbohydrate (1.2 g · kg body mass(-1) · h(-1)) or carbohydrate with protein (0.4 g · kg body mass(-1) · h(-1)) before, during, and after a rugby union-specific protocol. Markers of muscle damage (creatine kinase: before, 258 ± 171 U · L(-1) vs. 24 h after, 574 ± 285 U · L(-1); myoglobin: pre, 50 ± 18 vs. immediately after, 210 ± 84 nmol · L(-1); P < 0.05) and muscle soreness (1, 2, and 3 [maximum soreness = 8] for before, immediately after, and 24 h after exercise, respectively) increased. Leg strength and repeated 6-s cycle sprint mean power were slightly reduced after exercise (93% and 95% of pre-exercise values, respectively; P < 0.05), but were almost fully recovered after 24 h (97% and 99% of pre-exercise values, respectively). There were no differences between trials for any measure. These results indicate that in experienced rugby players, the small degree of muscle damage and reduction in function induced by the exercise protocol were not attenuated by the ingestion of carbohydrate and protein.     

MyTeachingPartner-Math/Science pre-kindergarten curricula and teacher supports: Associations with children's mathematics and science learning

MyTeachingPartner-Math/Science (MTP-MS) is a system of two curricula (math and science) plus teacher supports designed to improve the quality of instructional interactions in pre-kindergarten classrooms and to scaffold children's development in mathematics and science. The program includes year-long curricula in these domains, and a teacher support system (web-based supports and in-person workshops) designed to foster high-quality curricular implementation. This study examined the impacts of the intervention on the development of mathematics and science skills of 444 children during pre-kindergarten, via school-level random assignment to two intervention conditions (Basic: MTP-M/S mathematics and science curricula, and Plus: MTP-M/S mathematics and science curricula plus related teacher support system) and a Business-As-Usual control condition (BaU). There were intervention effects for children's knowledge and skills in geometry and measurement as well as number sense and place value: Children in Plus classrooms made greater gains in geometry and measurement, compared with those in BaU classrooms. Children in Plus classrooms also performed better on the number sense and place value assessment than did those in Basic or BaU classrooms. We describe the implications of these results for supporting the development of children's knowledge and skills in early childhood and for developing and providing teachers with professional development to support these outcomes.     

Data Collection Strategies and Measurement Tools for Assessing Academic and Therapeutic Outcomes in Recovery Schools

Accurate evaluation and documentation of the efficacy of recovery schools can be vital to the continuation and expansion of these beneficial resources. A very limited data set currently exists that examines the value of specific schools established to support adolescents and young adults in recovery; additional research is necessary. The following article outlines the methodology utilized in a current quasi-experimental study evaluating both academic and therapeutic outcomes of adolescents attending recovery high schools as compared to traditional (non-recovery-based) high schools. The developmental considerations in assessing adolescents in recovery and their parents is delineated in this article, which underscores the need for extensive knowledge of adolescent substance abuse and other mental health issues. In addition, sensitivity around privacy among adolescents, parents, schools, and health providers is highlighted, as well as the validity of assessment. Key assessment strategies, including protocol of recruitment and interviewing techniques, are also presented along with a list of parent and adolescent assessment instruments and their corresponding interpretive variables. Protocol recommendations for future research are also outlined.     

Interpreting histograms. As easy as it seems?

Histograms are widely used, but recent studies have shown that they are not as easy to interpret as it might seem. In this article, we report on three studies on the interpretation of histograms in which we investigated, namely, (1) whether the misinterpretation by university students can be considered to be the result of heuristic reasoning, (2) whether we could influence performance by stimulating or hindering the analytic processing of histograms, and (3) whether experts still show signs of this heuristic misinterpretation. We found that both university students and experts show signs of incorrect heuristic reasoning when comparing the mean of two data sets presented by histograms. Stimulating or hindering analytic processing did not affect performance. These indications of heuristic reasoning and the impossibility to affect this analytic processing suggest that the incorrect heuristic misinterpretation of histograms is very persistent. Implications for theory and methodology, scientific and educational practice are discussed.     

‘Hot’, ‘cold’ and ‘warm’ information and higher education decision-making

This paper draws on the notions of ‘hot’ and ‘cold’ knowledge in analysing the responses of students to the relevance of different information and sources of such information in university choice. Analysis of questionnaire and focus group data from prospective and first-year undergraduate students provides evidence that many students put most credence on ‘hot’ knowledge, from persons in their social grapevine. However, this is supplemented by ‘warm’ knowledge from fleeting acquaintances at university open days. University provided knowledge is often distrusted. We discuss the implications of this given the recent government emphasis in England on the role of information provision in helping students to make informed decisions, including the relevance to the ‘fair access’ agenda.     

Engagement and academic promotion: a review of the literature

Universities in Australia are becoming increasingly concerned with their reputation as ‘engaged’ institutions. Yet there is significant confusion about what this idea of ‘engagement’ means and no clear way of measuring or reporting it. In part, this is because of the nature of engagement itself which is dependent on local context, partnerships and communities. This presents a difficulty for academic staff undertaking engaged work within institutions and stresses the need for institutions to develop internal processes that clearly articulate definitions of engagement, set out performance expectations and provide processes for the reward and recognition of the scholarship of engagement. In a sector increasingly concerned with the outputs of research as measurable by publication bibliometrics and grant income, the sometimes difficult to measure outcomes of engaged work can become relegated and dismissed. As part of a project to articulate performance expectations in the area of the scholarship of engagement for academic promotion at the University of Wollongong, researchers undertook an extensive international literature review to learn what had been done in this area previously and to identify issues of concern. This paper sets out the findings from this review, considers the implications of engaged scholarship for academic promotion and suggests some possible ways forward for institutions and staff working in this area.     

Implementing Recommendations for Introductory Biology by Writing a New Textbook

We redesigned the undergraduate introductory biology course by writing a new textbook (Integrating Concepts in Biology [ICB]) that follows first principles of learning. Our approach emphasizes primary data interpretation and the utility of mathematics in biology, while de-emphasizing memorization. This redesign divides biology into five big ideas (information, evolution, cells, emergent properties, homeostasis), addressing each at five levels of organization (molecules, cells, organisms, populations, ecological systems). We compared our course outcomes with two sections that used a traditional textbook and were taught by different instructors. On data interpretation assessments administered periodically during the semester, our students performed better than students in the traditional sections (p = 0.046) and exhibited greater improvement over the course of the semester (p = 0.015). On factual content assessments, our students performed similarly to students in the other sections (p = 0.737). Pre- and postsemester assessment of disciplinary perceptions and self-appraisal indicate that our students acquired a more accurate perception of biology as a discipline and may have developed a more realistic evaluation of their scientific abilities than did the control students (p < 0.05). We conclude that ICB improves critical thinking, metacognition, and disciplinary perceptions without compromising content knowledge in introductory biology.     

Introducing the First Hybrid Doctoral Program in Educational Technology

In 2010 Michigan State University launched the first hybrid doctoral program in Educational Technology. This 5-year program blends face-to-face and online components to engage experienced, working education professionals in doctoral study. In this paper, we describe the design and evolution of the program as well as the response from students. We outline key programmatic challenges and opportunities in offering a hybrid doctoral program side by side with an existing face-to-face program. We conclude with two examples of the hybrid doctoral program in action (redesigning coursework and virtual talks) to demonstrate how we confronted these challenges and opportunities in the design of the program.     

Enhancing life skills development: Chinese adolescents’ perceptions

This study explored Chinese adolescents’ perceptions of their own life skills development and the importance they place on such skills. The study also investigated the within‐school and outside‐school influences that may help develop and enhance life skills development. Six focus groups involving 52 high school students were conducted, using a set of predetermined discussion topics. Results revealed students’ awareness of many salient life skills, including those related directly to academic development, ‘learning to learn’, personal and social growth, and future career planning. The students were also able to suggest practical strategies that schools might use to further enhance students’ life skills development. Contextual factors influencing the development of life skills appear to include not only experiences within the school curriculum and the guidance and counseling program, but also talent development opportunities, and family and peer relationships. The implications of the findings are discussed with particular reference to implementing comprehensive school guidance and counseling programs in Hong Kong.
