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.     

The relationship between segmental kinematics and ball spin in Type-2 cricket spin bowling

The techniques of spin bowling in cricket have been largely formulated from the collective intuitions of past players. A standard model of bowling technique has been generally prescribed for both off-spin and leg-spin bowlers, but there has been no biomechanics research to validate this approach. This study measured 20 Type-2 off-spin and 15 Type-2 leg-spin bowlers using a 3D Cortex motion analysis system. Correlation coefficients between segmental kinematic variables and spin rate in the off-spin and leg-spin bowlers revealed that off-spin bowling was associated with an earlier movement time of the thorax, whereas leg-spin bowling was associated with a greater magnitude and earlier movement time of pelvis rotation, as well as a greater magnitude of pelvis-shoulder separation movement. The maximum velocity of rear hip flexion differentiated between both groups of bowlers. The GLM suggested that for off-spinners, rear hip flexion velocity significantly explained the variance in spin rate (subject to sequential timing constraints), while for leg-spinners, the time of maximum rear hip flexion and maximum arm circumduction velocity significantly explained variance in spin rate. This study supports the notion that off-spinners and leg-spinners have significant differences in their joint kinematics, and should not be coached under a one-size-fits-all technical model.     

Contribution of uncertainty in estimation of active drag using assisted towing method in front crawl swimming

Active drag force in swimming can be calculated from a function of five different variables: swim velocity, tow velocity, belt force, power output and exponent of velocity. The accuracy of the drag force value is dependent on the accuracy of each variable, and on the contribution of each variable to drag estimation. To calculate uncertainty in drag value, first the derivatives of the active drag equation with respect to each variable were obtained. Second, these were multiplied by the uncertainty of that variable. Twelve national age and open level swimmers were recruited to complete four free swimming and five active drag trials. The uncertainties for the free and the tow swim velocities, and for the belt force, contributed approximately 5–6% and 2–3% error, respectively, in calculation of drag. The result of the uncertainty of the velocity exponent (1.8–2.6) indicated a contribution of about 6% error in active drag. The contribution of unequal power output showed that if a power changed 7.5% between conditions, it would lead to about 30% error in calculated drag. Consequently, if a swimmer did not maintain constant power output between conditions, there would be substantial errors in the calculation of active drag.     

Let's Talk About Sex … Education

An important goal of any sexuality education program is to support youth and young adults to develop a positive self-image and develop competence and confidence in skills needed to express sexuality and develop positive relationships. For youth and young adults with disabilities, sexuality education is offered far less often than for their same aged peers without disabilities. This article describes a three-step process for developing specially designed instruction in sexuality education using principles of instructional design to meet the unique needs of students with disabilities.     

Get real: making problematic the pathway into the teaching profession

Learning to be a teacher is a complex and very personal matter that involves transformation from student teacher (pre‐service teacher) to teacher. The pathway to being a teacher is scattered with what appears to be competing tensions in various realities. This paper explores those tensions and realities through the context of two final year integrated field‐ and campus‐based subjects that all pre‐service teachers undertake as they complete their four‐year teacher education journey into the primary (ages 5‐ to 12‐years‐old) teaching profession. We then propose a framework involving a variety of realities that pre‐service teachers face through the recognition and resolution of the tensions these pre‐service teachers experience in the workplace.     

Detecting Differential Item Functioning Using Logistic Regression Procedures

A logistic regression model for characterizing differential item functioning (DIF) between two groups is presented. A distinction is drawn between uniform and nonuniform DIF in terms of the parameters of the model. A statistic for testing the hypothesis of no DIF is developed. Through simulation studies, it is shown that the logistic regression procedure is more powerful than the Mantel-Haenszel procedure for detecting nonuniform DIF and as powerful in detecting uniform DIF.     

Emotion regulation and academic perceptions in adolescence

Although studied extensively in the field of adolescent mental health, the role of emotion regulation (ER) in the academic functioning of adolescents is not well understood. This study examined the role of ER in adolescents’ perceptions of themselves and their learning environments. We compared adolescents with high and low levels of ER on perceptions of school achievement and attitudes towards school and their perception of their parents’ academic involvement. Students completed surveys about perceptions of their learning and parental involvement, as well as their ER abilities. Results indicated that students with higher emotion dysregulation endorsed more negative self-perceptions of their own academic abilities, had more negative attitudes towards school, and rated their mothers and fathers as more controlling in relation to their learning. These results demonstrate the importance of ER in the academic context, particularly in the home learning environment.     

SIDE-VIEW: Evaluation of a system to develop team players and improve productivity in Internet collaborative learning groups

This paper briefly summarizes the initial development of a computer-supported collaborative learning environment and evaluates its effects in relation to the productivity of CSCL groups. The design of the SIDE-VIEW system is driven by the social identity approach to understanding group behaviour and is premised upon the need to establish congruity between the self-definition of group members and their collaborative learning tasks. We begin by outlining the rationale for the system in relation to productivity and the emergence of team players within collaborative learning groups. We then describe aspects of the design that are intended to enhance both, and report on a field trial of the initial prototype on international groups of higher education students. The preliminary results of the field study indicate that aspects of the design encourage the emergence and influence of team players within groups, with consequential improvements to the quality of the group output. The role of team players in CSCL groups is contrasted with that of group leaders.     

Investigating the impact of NAPLAN on student,parent and teacher emotional distress in independent schools

Concerns have been raised about the impact Australia’s national standardised testing, the National Assessment Program-Literacy and Numeracy (NAPLAN), has upon the well-being of students, parents and teachers. To date, research evidence is unclear as to the level and extent of emotional distress experienced by stakeholders during testing. Despite an unclear evidence base, the prevailing view is that NAPLAN has a general negative impact upon stakeholder well-being. In a pilot study that surveyed all stakeholder groups across 11 independent schools in Western Australia, we found evidence of a minimal impact from the testing. We also found evidence for a small positive association between student and parent distress during testing, and a moderate positive association between parent and teacher distress during testing and their estimations regarding how NAPLAN impacts other people. Our results are not consistent with the prevailing view that NAPLAN has a broad negative impact on well-being, and highlights the need for further research to inform debates about the usefulness and impact of NAPLAN testing.
