Categorising computer science education research

The interdisciplinary nature of Computer Science Education as a field of study is a complicating factor when authors are choosing appropriate journals and conferences for publishing research results. This paper reports a survey of 42 such publications in order to identify the types of paper frequently accepted for publication in each. We review existing taxonomies developed for the general fields of Computer Science and Education, and from this starting point, we develop a novel faceted taxonomy, specifically aimed to help new researchers in the field understand what types of papers are published and where they appear. Our results confirm previous studies indicating the predominance of practice-based, technology-driven reports. We also observe certain differences in educational themes between those found in publications grounded in the Computer Science Education corpus and those emerging from more general Higher Education literature.     

Learning to talk: community support and views of parents from socially disadvantaged families

Part of a multimethod ethnographic study that aimed to explore the knowledge of local parents concerning children learning to talk is described. The study was carried out with parents from several different ethnic and language groups in a socially disadvantaged part of Sheffield, a large city in the northeast of England.
In the phase of the study reported here, parents (either English, Urdu/Punjabi and Arabic speakers) took part in interviews, as well as contributing to the validation of the project. This study found that parents from diverse cultural and linguistic backgrounds living in this socially disadvantaged area, believed learning to talk to be very important and that family, community, including faith community, and professionals, have roles in promoting learning to talk. They indicated that local community groups, including faith communities, could play a positive role in supporting and developing their knowledge.
This paper will be of interest to those seeking innovative ways to support parents in socially excluded communities, particularly parents of children learning to talk, and so contribute to better outcomes for children, families and communities. It also contributes to our understanding of the development of parental knowledge about learning to talk in socially disadvantaged communities.     

FROM PISA TO EDUCATIONAL STANDARDS: THE IMPACT OF LARGE-SCALE ASSESSMENTS ON SCIENCE EDUCATION IN GERMANY

The German education system does not traditionally rely on standardized testing. However, when the Programme for International Student Assessment (PISA) study revealed an average performance of German students compared to other participating countries, a particular proportion of low-performing students, and remarkable disparities between the federal states, German policy makers decided for a major reform of the education system. A core piece of this reform was the introduction of National Education Standards. For science education, these standards were heavily influenced by the PISA results and its underlying framework. That is, with the standards, a paradigm shift took place from the German notion of Bildung towards the Anglo-American notion of literacy. With the introduction of these standards, a new field of empirical educational research was created: research on models of scientific literacy or competency models as a basis of benchmarking the standards. This article describes the German education system before PISA, summarizes the major findings from PISA, and describes how these findings informed the formulation of the performance standards for science education. It also details the measures undertaken to benchmark these standards. Finally, it provides insight into the issues with developing and benchmarking performance standards and points out future areas of research on evidence-based decision making in educational policy.     

Implementing the UN Decade of Education for Sustainable Development (DESD): achievements, open questions and strategies for the way forward

This paper looks at the implementation of the DESD from a global perspective. It takes the position that quality education is fundamental for learning how to live sustainably, and that the DESD needs to be better positioned in the education landscape and conceived as a global social movement that must be fostered and nurtured for the well-being of humankind. It suggests that, while there has been progress, much remains to be achieved. Several key challenges are identified. With regard to overcoming these obstacles, it focuses on macro-level strategies that would allow the development of environments in which actions can take root and grow so that the work of the DESD endures beyond the decade itself. Finally, it suggests that there are some opportunities that can be seized to make the task ahead easier to accomplish.     

The Academic Influence of Mentoring Upon African American Undergraduate Aspirants to the Professoriate

In this study, I examine academic influences of the Committee on Institutional Cooperation Summer Research Opportunity Program’s mentoring component. Interviews with African American undergraduate student participants of the faculty–student mentoring initiative suggest mentorship’s influence upon the academic experiences of participants and illustrate the importance of faculty-directed research in preparing racial minorities for graduate education.     

Fatigue-related changes in technique emerge at different timescales during repetitive training

Training consisting of numerous repetitions performed as closely as possible to ideal techniques is common in sports and every-day tasks. Little is known about fatigue-related technique changes that emerge at different timescales when repeating complex actions such as a karate front kick. Accordingly, 15 karatekas performed 600 kicks (1 pre-block and 9 blocks). The pre-block comprised 6 kicks (3 with each leg) at maximum intensity (K-100%). Each block comprised 60 kicks (10 with each leg) at 80% of their self-perceived maximum intensity (K-80%) plus 6 K-100%. In between blocks, the participants rested for 90 seconds. Right leg kinematics (peak joint angles, peak joint angular velocities, peak joint linear resultant velocities, and time of occurrence of peaks) and kick duration corresponding to the K-80% were measured resulting in numerous variations with fatigue. At the timescale of tens of seconds, the changes involved variables that were related to velocity of execution (slowed down), while variables related to movement form were hardly affected. At the timescale of tens of minutes, the opposite results were observed. These findings challenge the long-standing rationale underlying repetitive training, suggesting instead that such involuntary variations in technique might play a crucial role in motor skill training     

Relationships between performance test and match-related physical performance parameters

Background

The purpose of this study was to analyze the relationship between performance test parameters and match-related physical performance in professional soccer players.

Methods

To determine physical capacity, 28 male soccer players underwent several performance tests at the start of the seasons 2013/2014, 2014/2015, and 2015/2016. The following parameters were assessed: maximum running velocity (v_max), fixed (v_4mmol/l) and individual anaerobic threshold (v_IAS) during an incremental treadmill test; 30-m sprint time in a linear sprint test (LS_30m); in a repeated-sprint test, the 30-m sprint time (RST_30m) and performance decrement (RST_decr); and countermovement jump height (CMJ). Match physical performance was quantified during the first ten official matches of each season using a computerized, camera-based tracking system. The following measures of match physical performance were considered: top running speed (TS), mean running speed (v_Ø), total distance covered (TD), number of sprints (SP), number of high-intensity running (HIR), and aerial duels won (AD+). Pearson correlation coefficients were used for statistical analysis.

Results

Moderate to very large correlations were found between the majority of performance test parameters and match performance variables, with a variability of correlations across the three seasons. Large relationships across all three seasons were only observed between v_max and TD, v_max and v_Ø, LS_30m and TS as well as RST_30m and TS.

Conclusion

This study demonstrates the relationship between several performance test parameters and match-related physical performance in professional soccer players, thereby supporting the test parameters’ criterion validity. v_max, LS_30m, and RST_30m seem to be the most consistent parameters.

     

Feasibility for the Use of a Standardized Fitness Testing Protocol Among Australian Fitness Industry Professionals

Purpose: There is currently no standardized testing protocol for assessing clients’ fitness/health within the Australian fitness industry. This study examined the perceptions of the feasibility of using a standardized testing protocol among Australian fitness industry professionals. Method: In 2014, 1,206 registered fitness industry professionals (aged 17–69 years) completed an online survey. Perceived feasibility for using a standardized testing protocol was assessed based on responses to 6 items. Respondents were classified as having a high level of perceived feasibility if they reported all 6 items to be “definitely feasible.” A multivariate logistic regression analysis, adjusting for demographic and fitness industry-related factors (e.g., qualification/years of experience), assessed the likelihood of having a high level of perceived feasibility. Results: Overall, 25.5% (95% CI [23.1%, 28.0%]) of the sample perceived the use of a standardized testing protocol as highly feasible. Items ranked most often as “definitely feasible” were “undertaking training to use the protocol” (55%) and “conducting follow-up testing every 6 to 12 weeks” (52%). After adjustment for the effect of confounding factors, casually employed professionals (OR = 0.63; 95% CI [0.45, 0.90]) and group instructors (OR = 0.58; 95% CI [0.41, 0.82]) were less likely to perceive standardized testing protocols as highly feasible. Conclusions: Among a large sample of Australian fitness industry professionals, slightly more than a quarter perceived using a standardized testing protocol to be highly feasible. Group instructors and casual employees perceived lower feasibility. Further research should determine the barriers to implementing a standardized testing protocol across the fitness industry.
