Ethical issues of behavior modification research in schools

Behavior modification research in the classroom was examined by the National Commission for the Protection of Human Subjects because of the increasingly widespread use of behavioral procedures in the schools, the effectiveness of these procedures in changing academic and social behavior, and the consequent concern about potential misuse. In order to foster the responsible use of behavior modification procedures in the schools on a practical as well as a research basis, the following ethical issues being considered by researchers and the involved public are discussed: informed consent, determination of classroom goals, legitimacy of rewards and aversive controls in the classroom, conceptions of behavior modification as manipulative and mechanistic, who can implement the procedures, research design, and accountability. The authors conclude that the issues regarding protection of human subjects in behavior modification research are no different from other treatment-oriented research with children. However, the high degree of parental and teacher involvement in both research and practice requires shared responsibility for the prevention of misuse of behavior modification procedures.

Mediating effects of resistance training skill competency on health-related fitness and physical activity: the ATLAS cluster randomised controlled trial

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.     

Multivariate analyses of individual variation in soccer skill as a tool for talent identification and development: utilising evolutionary theory in sports science

The development of a comprehensive protocol for quantifying soccer-specific skill could markedly improve both talent identification and development. Surprisingly, most protocols for talent identification in soccer still focus on the more generic athletic attributes of team sports, such as speed, strength, agility and endurance, rather than on a player’s technical skills. We used a multivariate methodology borrowed from evolutionary analyses of adaptation to develop our quantitative assessment of individual soccer-specific skill. We tested the performance of 40 individual academy-level players in eight different soccer-specific tasks across an age range of 13–18 years old. We first quantified the repeatability of each skill performance then explored the effects of age on soccer-specific skill, correlations between each of the pairs of skill tasks independent of age, and finally developed an individual metric of overall skill performance that could be easily used by coaches. All of our measured traits were highly repeatable when assessed over a short period and we found that an individual’s overall skill – as well as their performance in their best task – was strongly positively correlated with age. Most importantly, our study established a simple but comprehensive methodology for assessing skill performance in soccer players, thus allowing coaches to rapidly assess the relative abilities of their players, identify promising youths and work on eliminating skill deficits in players.     

Teaching Them to Teach: Programmatic Evaluation of Graduate Assistants’ Teaching Performance

Academic libraries are one of the most important sources of “on the job” training for future library instructors. Librarians who supervise and assess these future library instructors (often in graduate assistant positions) often choose to provide observations and feedback each semester to these instructors in training. Scholarly literature, however, provides little information on whether this system helps graduate assistants to develop as teachers. The authors of this article assessed graduate assistants’ performance as teachers over three semesters using a system of observation and self-assessment. They analyzed both patterns and areas of growth and discuss the strengths and weaknesses of this system.     

Evaluating the Instructional Sensitivity of Four States' Student Achievement Tests

As state tests of student achievement are used for an increasingly wide array of high- and low-stakes purposes, evaluating their instructional sensitivity is essential. This article uses data from the Bill and Melinda Gates Foundation's Measures of Effective Project to examine the instructional sensitivity of 4 states' mathematics and English language arts assessments to 5 measures of pedagogical quality. The results indicate modest overall levels of sensitivity, with some state assessments insensitive to most or all measures of pedagogical quality. Furthermore, there are sometimes substantial differences across states in the sensitivity of their assessments. The article calls for more research on what makes state tests instructionally sensitive and cautions against the use of insensitive assessments for consequential decisions.     

Conceptualizing Service-Learning in Christian Higher Education

Christian higher education is charged with the distinct mission of integrating faith and learning, and course-based service-learning has been identified as a supportive platform for this undertaking. Christian service-learning represents "a teaching and learning strategy that integrates academic instruction, community service, and guided reflection from a Christ-centered, faith-based perspective in order to enhance student learning, to foster civic responsibility, and to develop servant leaders” (Mullen, 2010 Mullen, S. (2010). Integrating a service and learning paradigm in a Christian education environment. Christian Education Journal, 7(1), 162–171.[Crossref] , [Google Scholar], p. 164). A large volume of literature pertaining to the theoretical and practical aspects of service-learning courses exists; however, the current literature and corresponding perceptions of best practice may not fully support the distinct nature of service-learning in Christian higher education. Therefore, the purpose of this article is to examine a predominant service-learning typology that dichotomizes traditional and critical service-learning (Mitchell, 2008 Mitchell, T. D. (2008). Traditional vs. critical service-learning: Engaging the literature to differentiate two models. Michigan Journal of Community Service Learning, 14(2), 50–65. [Google Scholar]) through the contextualization of faith-based higher education. Then, in an attempt to further elaborate upon Mullen’s (2010 Mullen, S. (2010). Integrating a service and learning paradigm in a Christian education environment. Christian Education Journal, 7(1), 162–171.[Crossref] , [Google Scholar]) definition, Morton’s (1995 Morton, K. (1995). The irony of service: Charity, project, and social change in service learning. Michigan Journal of Community Service Learning, 2(1), 19–32. [Google Scholar]) typology is recommended to frame Christian service-learning as it acknowledges the validity of multiple paradigms of service-learning (charity, project, and social change) and emphasizes the manner of their implementation (thick versus thin). Micro- and macro-level strategies, based on Morton’s (1995 Morton, K. (1995). The irony of service: Charity, project, and social change in service learning. Michigan Journal of Community Service Learning, 2(1), 19–32. [Google Scholar]) typology and subsequent recommendations, are provided to support faculty members and administrators attempting to implement and sustain service-learning at faith-based institutions. Specifically, Christian institutions should prioritize faith-based organizations as core partners, and faculty members should intentionally utilize reflection to integrate faith and learning.     

Rats remember not wisely but too well

Rats were trained in a three-alternative spatial delayed matching-to-sample task in a starburst maze. Samples consisted of rewarded forced choices of one arm, and retention was indicated by rats’ returning to that arm after a 90-sec delay. If a rat made an error on its first choice, it was returned to the start compartment and allowed a second choice. Unlike in previous experiments with this task, all three arms were available during the animals’ second choices. The rats tended to perseverate in their second choices by returning to the arm that they had erroneously visited on their first choice. In Experiment 1, the accuracy of second choices following first-choice errors was below chance during the first block of sessions, when a 90-sec delay intervened between the first choice and the second choice, and at chance during the second block of sessions, when a short (5–6 see) delay intervened between first and second choices. In Experiment 2, long-delay and short-delay sessions were randomly presented to naive subjects. Similar results were obtained. In both experiments, the tendency to repeat the erroneous first choice was greater when long delays separated the two choices than when short delays were used. The results suggest that rats make their first-choice errors because they erroneously encode or remember the location of the sample and that they base their second choices on the same erroneous-memory. The increase in perseveration at long delays implies some kind of rehearsal-like mechanism that slows forgetting of the memory controlling the first choice.     

Count us in: the role of schools and colleges in meeting the mental health needs of young people with learning disabilities

In December 2002, the Foundation for People with Learning Disabilities' Committee of Inquiry into the mental health needs of young people with learning disabilities produced its report.
Barry Carpenter, Chief Executive at Sunfield and Chair of the committee, and Hazel Morgan, head of the Foundation for People with Learning Disabilities, take this opportunity to share some insights into the workings of the committee and summarise the key findings. The committee drew evidence from a range of sources, but placed the voices and experiences of young people with learning disabilities at the centre of their proceedings. The committee's findings and recommendations were wide ranging and will have far-reaching implications, but there are immediate messages that schools and colleges should hear. It is upon these messages, taking account of pastoral provision, the curriculum, transition and inter-agency work, that Barry Carpenter and Hazel Morgan focus in this article.
