Using collaborative technology to enhance pre-service teachers’ pedagogical content knowledge in Science

Groups of 11‐year‐olds in their first term at secondary school were given three cognitive tests. Girls and boys were found to be approximately equal in science knowledge. Boys did slightly better on tests of physical science, especially when these were in multiple choice form, but otherwise there were few sex differences. Neither the style of the question (multiple choice or structured) nor the content (feminine or masculine) had any great effect on sex differences in performance. However, boys performed markedly better than girls on tests of spatial ability and mechanical reasoning. These skills may be important for later success in technical studies at school.     

Enabling connections in postgraduate supervision for an applied eLearning professional development programme

This article describes the practice of postgraduate supervision on a blended professional development programme for academics, and discusses how connectivism has been a useful lens to explore a complex form of instruction. By examining the processes by which supervisors and their students on a two-year part-time masters in Applied eLearning negotiated the blended approach adopted to supervision, it illustrates the conditions that enable connections to occur and flourish. The socio-technical context for supervision was supported using learning technologies (VLE, research wikis and ePortfolios), small group supervision (two to three supervisors and students) and traditional individual supervision. Qualitative data were obtained through surveys and focus groups, and analysed using a framework which drew on connectivist principles. Findings suggest that for increased connections between supervisors and their students, a sense of sanctuary, community and regulation within the supervision process is important; the role of technologies in unifying postgraduate supervision in professional development are discussed.     

Charting the waves of prevention: two steps forward,one step back

BACKGROUND: Over the past 30 years, the political response to child maltreatment and its prevention in the US has experienced periods of frantic activity, often followed by long periods of benign neglect. In reflecting on this history, Dick Krugman has referred to this uneven level of attention as a series of "waves" in which apparent progress is often minimized by an inability to sustain political commitment to a given reform or course of action. To an extent, this pattern reflects deep differences among child welfare advocates, researchers, and practitioners on how best to proceed. While most everyone agrees that "it shouldn't hurt to be a child," how to prevent this hurt and at what cost is less clear. METHOD: To address this dilemma, prevention advocates, researchers, and practitioners have struggled with a variety of conceptual frameworks and programmatic reforms. This article summarizes the relative gains and limitation of three such efforts and outlines the lessons these efforts offer those formulating future prevention policies and programs. RESULTS: Specifically, the authors suggest that future prevention efforts will need to take care in avoiding some of the most common mistakes experienced by earlier efforts. CONCLUSIONS: These mistakes or pitfalls include oversimplifying the problem of child abuse; overstating preventions' potential and appropriate target populations; failing to establish a significant partnership with child protective services; compromising depth or quality in an effort to maximize breadth or coverage; and failing to fully engage the public.     

Preservice elementary teachers' perceptions of their science laboratory instructors in a phenomena-based laboratory and how it impacts their conceptual development

Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory instructors, both of whom may have had limited opportunities to learn or teach science within the student and instructor roles inherent within these approaches. This study uses a convergent parallel mixed-methods approach to investigate PSETs' perceptions of their laboratory instructor's role within a Physical Science phenomena-based laboratory curriculum and how it impacts their conceptual development (2 instructors/121 students). We also examine how the two laboratory instructors' discursive moves within the laboratory align with their's and PSETs' perceptions of the instructor role. Qualitative data includes triangulation between a student questionnaire, an instructor questionnaire, and video classroom observations, while quantitative data includes a nine-item open response pre-/post-semester conceptual test. Guided by Mortimer's and Scott's analytic framework, our findings show that students primarily perceive their instructors as a guide/facilitator or an authoritarian/evaluator. Using Linn's knowledge integration framework, analysis of pre-/post-tests indicates that student outcomes align with students' perceptions of their instructors, with students who perceive their instructor as a guide/facilitator having significantly better pre-/post-outcomes. Additional analysis of scientific discourse from the classroom observations illustrates how one instructor primarily supports PSETs' perspectives on authentic science learning through dialogic–interactive talk moves whereas the other instructor epistemologically stifles personally relevant investigations with authoritative–interactive or authoritative–noninteractive discourse moves. Overall, this study concludes by discussing challenges facing laboratory instructors that need careful consideration for phenomena-based approaches.     

Examining the impact of the Respect in Sport Parent Program on the psychosocial experiences of minor hockey athletes

ABSTRACT

Models of positive youth development suggest that athletes may be influenced by parent education programmes; however, there is little research examining the impact of such programmes on athlete outcomes. This study examined the impact of the Respect in Sport Parent Program on athlete outcomes among minor hockey players over three years. This study consisted of cross-sectional and longitudinal online surveys measuring athletes’ positive and negative developmental experiences, prosocial and antisocial behaviours, parental support and pressure, and sport enjoyment and commitment. Athletes completed at least one online survey during the study period (N = 366; 84.2% males; 14–19 years of age; M = 15.4 years), and 83 athletes completed multiple surveys for longitudinal analyses. Cross-sectional results comparing athletes in leagues adopting the programme at different time points indicated significant differences in prosocial behaviours towards teammates. Multilevel longitudinal analyses revealed improvements in athletes’ antisocial behaviours towards opponents, initiative, goal setting, and cognitive skills over time, regardless of whether they were in a league that implemented the programme. However, athletes in leagues that implemented the programme during the study reported greater improvements in antisocial behaviours towards opponents, and there were trends with respect to improved personal and social skills. These findings provide suggestions to improve the delivery and impact of parent education programmes in youth sport.     

Conducting research in sports engineering education

This aim of this paper is to provide recommendations for developing sports engineering education research (SEER) both at the individual and community levels. The emergence of this field can be positively informed by reflection on similar developments in other fields, particularly engineering education and health science education research. The large traditional engineering disciplines, including chemical, electrical and computer, and mechanical, have well-developed communities and publication venues for educational research. Health professions, including kinesiology, rehabilitation, nursing, and medicine, have allied with sports engineering to develop educational research that can inform methods and provide opportunities for dissemination. As an interdisciplinary field, it is also critical to draw on the growing body of interprofessional education research. The rich literature relating to discipline-based educational research (DBER) and the Scholarship of Teaching and Learning (SoTL) can support individuals moving into this field, and observations by communities in other disciplines can provide guideposts for sports engineering. There are well-established processes and methodologies that can be adapted from other discipline-based educational research fields. As stand-alone sports engineering education programs are relatively rare and young, there is an opportunity available to create a culture that values research on education in the field.     

How well do evidence-based universal parenting programs teach parents about psychological maltreatment?: a program review

Objective

Psychological maltreatment (PM) is a widespread form of child maltreatment both in high-risk and maltreating families as well as in the general population of parents, yet there are no intervention programs that target it directly. The current study was designed as the first step in a larger program of research concerning educating parents about PM. In this study we evaluated the content of universal parenting programs to assess whether they include content on PM. Three questions were addressed: (1) Which types, if any, of PM were included in the content of these programs? (2) Which programs, if any, have content about each of the types of PM? (3) What are the implications for the development of PM curricula for parents?

Method

Ten evidence-based, manualized, universal parenting programs identified from SAMHSA or a comparable model program registry were rated on how well their content covered 18 types of psychological maltreatment (PM), as defined by the American Professional Society on the Abuse of Children, APSAC ( [Bingelli et al., 2001] and [0160] ). Each type of PM was coded along several dimensions which resulted in two summary scores: (1) Does the program contain content designed to teach parents what not to do in regards to the 18 psychologically maltreating behaviors and (2) Does the program contain content designed to teach parents what to do instead?

Results

Content related to most PM types were not included in the curricula, especially regarding “what not to do” and not one program was rated as having content related to teaching all 18 types of PM.

Conclusions

Existing parenting programs do not currently cover content for teaching community parents about psychological maltreatment.     

Indirect evidence of human skeletal muscle damage and collagen breakdown after eccentric muscle actions.

Indirect markers of muscle damage and collagen breakdown were recorded for up to 9 days after a bout of concentric, followed by a bout of eccentric, muscle actions. Nine untrained participants performed two bouts of 50 maximum effort repetitions on an isokinetic dynamometer (angular velocity 1.05 rad x s(-1), range of motion 1.75 rad). An initial concentric bout of muscle actions was followed by an eccentric bout 21 days later, using the same knee extensors. Concentric actions induced no changes in maximum voluntary isometric contraction force (MVC), nor induced any changes in the serum enzyme activities of creatine kinase, a lactate dehydrogenase isoenzyme (LDH-1), or alkaline phosphatase. Similarly, concentric actions induced no change in markers of collagen breakdown, namely plasma hydroxyproline and serum type 1 collagen concentration. In contrast, eccentric actions induced a 23.5+/-19.0% (mean+/-s) decrease in MVC immediately post-exercise (P < 0.05), and increased the serum enzyme activities of creatine kinase and LDH-1 to 486+/-792 and 90+/-11 IU.l(-1) respectively on day 3 post-exercise, and to 189+/-159 and 96+/-13 IU x l(-1) respectively on day 7 post-exercise (all P< 0.05). Eccentric actions induced no significant changes in plasma hydroxyproline, but increased collagen concentration on days 1 and 9 post-exercise (48.6% and 44.3% increases above pre-exercise on days 1 and 9 respectively; both P < 0.05). We conclude that eccentric but not concentric actions may result in temporary muscle damage, and that collagen breakdown may also be affected by eccentric actions. With caution, indices of collagen breakdown may be used to identify exercise-induced damage to connective tissue.     

Content analysis of computer conferencing transcripts

Within the field of higher education, there are situations where the learner is not well served in a classroom setting. Problematic issues such as scheduling, critical mass, time, pace and location have the potential to be counterbalanced by e-learning. Within this, the asynchronous nature of today's online learning environments and computer conferencing tools have popularly been claimed to offer tremendous benefits for learners who are willing to take responsibility for their own learning, to progress at their own pace, and interact with their online teacher to get immediate feedback on their learning and progress. Indeed, increasingly, educators today are very keen to exploit some of these new technologies for the benefit of their learners. It is argued in this article that there is a need to address the practice and research of asynchronous computer mediated conferencing. As conferencing tools become an increasingly common feature in students' experience, teachers need to have an understanding of how these tools facilitate the formation and maintenance of collaborative learning communities.
