Learning in honeybees as a function of amount of reward: Tests of the equal-asymptote assumption

In Experiments 1 and 2, honeybee foragers visiting the laboratory were fed on targets of two different colors, one containing 5 μl and the other containing 20 μl of 50% sucrose solution. The targets were presented singly in quasi-random sequences on the training visits, after which preference was measured in an unrewarded choice test. In Experiment 1, 16 differentially rewarded training trials with each color were followed by the same number of trials with the color-amount relation reversed; no preference for either color was found in the subsequent choice test. In Experiment 2, 20 differentially rewarded training trials with each color—enough to produce a clear preference for the 20-μl color when given directly after pretraining—were given after 10 feedings to repletion on each color that were calculated to generate near-asymptotic associative strength; no preference for either color was found in the subsequent choice test. In Experiment 3, there were 12 feedings to repletion on one color and, on the other, 12 feedings to repletion followed by 15 trials with a small (5 μl) reward; no preference was found in a subsequent choice test. The results of all three experiments support a nonrepresentational interpretation of the role of amount of reward in the learning of honeybees.     

Using Children’s Created Cultures: Culturally Appropriate Practice in the Primary Grades

In discussions about developmentally appropriate practice, the term “social and cultural context” is typically used to refer to the culture of children, their families, and their community. Those discussions do not usually address the unique cultures children sometimes create among themselves. Those cultures have values, rules, and norms that frequently exclude adults. As outsiders, we teachers often react to children’s created cultures by discounting them as something that interferes with education rather than something we can use. However, teachers can incorporate those cultures into their classrooms in effective ways that can enhance children’s motivation and facilitate learning.     

Supplemental Instruction: Understanding Academic Assistance in Underrepresented Groups

Student retention rates are increasingly important in higher education. Higher education institutions have adopted various programs in the hopes of increasing graduation rates and grade point averages (GPAs). One of the most effective attempts at improvement has been the Supplemental Instruction (SI) program. We examined our SI program relative to three facets: attendance, attendance's influence on final scores, and graduation rates for students who had participated in these courses. These questions were also investigated focusing on specific comparison groups, as we looked into how these effects differed for minority students and nontraditional students compared with those of White and traditional peers. Overall, SI attendance led to positive outcomes— increased final course grades and graduation rates—even after adjusting for previous achievement.     

Teachers as researchers: Classroom inquiry initiatives at undergraduate and graduate levels in early childhood education

Abstract

This article discusses the importance of including a teacher‐as‐researcher strand in college courses at both undergraduate and graduate levels. It describes four competency areas that contribute to the ability to engage in classroom inquiry including frequent and quality clinical experiences, practicing data collection methods of authentic assessment, opportunities to learn reflective practices, and experience using the inquiry cycle. Two undergraduate courses in early childhood education and a masters degree program in teaching & learning provide illustrations for embedding the teacher‐as‐researcher strand into the teacher education program. The article discusses the potential for classroom inquiry to stimulate renewal in university and public school settings. © 2001 Elsevier Science Inc. All rights reserved.     

The significance of theory in the implementation of curriculum change in religious education

A new study in Melbourne, Australia, has investigated curriculum change in religious education against the background of literature on curriculum change in education in general. Amongst its several findings, it was ascertained that clear information and theoretical understanding about a curriculum change in religious education is just as important as it is in any other field of study. In the absence of such information and understanding the leaders who were responsible for implementing the curriculum change in religious education made certain curriculum accommodations, and emphasised particular professional development activities for teachers that were not in keeping with the theoretical underpinning of the change. The implications for ‘top down’ curriculum change, such as those mandated by Church authorities or state authorities, are significant.     

Mapping the core journals of the physical therapy literature

Objectives:

The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals.

Method:

Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford''s Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007.

Results:

Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications.

Conclusions:

Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline.

Highlights

• More cited references were published in the last eight years studied than in any previous full decade.
• Physical Therapy, Archives of Physical Medicine and Rehabilitation (APMR), and Spine were the most frequently cited titles. Previous studies found APMR to be the most cited journal.
• CINAHL provided the highest coverage rate for the most commonly cited titles, with MEDLINE and EMBASE providing the best coverage for the next group of titles.

Implications

• Health sciences librarians and clinicians can use these results to identify important journals for developing collections and determining the need for access to back issues of journals.
• Multiple databases are needed for comprehensive coverage of the physical therapy discipline

Special Collections and Archives Code (SPAC): Preserving Provenance in a Bibliographic Catalog

The recording of provenance is of particular importance in special collections cataloging, as knowledge of provenance lends authenticity and reliability to the materials held. A method of cataloging collection-level provenance in bibliographic records through a short mnemonic code, a Special Collections and Archives Code (SPAC), is described which enhances visibility of collections and retrieval in a catalog. A collection code not only collocates unique individual items that share a common characteristic, but can also constitute part of a linked data approach to visualizing integrated collections in the form of a “virtual bookplate.”     

Digital service analysis and design: The role of process modelling

Digital libraries are evolving from content-centric systems to person-centric systems. Emergent digital services are interactive and multidimensional, associated systems multi-tiered and distributed. A holistic perspective is essential to their effective analysis and design, for beyond technical considerations, there are complex social, economic, organisational, and ergonomic requirements and relationships to consider. Such a perspective cannot be gained without direct user involvement, yet evidence suggests that development teams may be failing to effectively engage with users, relying on requirements derived from anecdotal evidence or prior experience. In such instances, there is a risk that services might be well designed, but functionally useless. This paper highlights the role of process modelling in gaining such perspective. Process modelling challenges, approaches, and success factors are considered, discussed with reference to a recent evaluation of usability and usefulness of a UK National Health Service (NHS) digital library. Reflecting on lessons learnt, recommendations are made regarding appropriate process modelling approach and application.     

Stepping out of the norm: an examination of praxis for a culturally‐relevant pedagogy for African‐American children

This paper examines two Anglo teachers' understanding of their praxis as they attempted to present a culturally‐relevant physical education programme to a class of African‐American 6^th‐grade students. In this case, the content was ‘stepping’, a branch of the African‐American vernacular dance tree. Five specific themes emerged: teacher apprehension; concerns about teacher legitimacy; resolution of apprehension and concerns; the unique nature of the content; and continual ethical uneasiness. The teachers expanded their understanding of praxis beyond thinking, acting, and reflecting to consider the political and social aspects that impact curriculum, pedagogy, and students.
