VINCE—an on-line tutorial tool for teaching introductory programming

We describe a tutorial tool which allows the execution of a C program to be graphically displayed. VINCE (Visual Instruction for Novices in a C Environment) is written in Java, allowing it to be used on the web. The student can enter their own C code, or select from a menu of pre-written tutorials, each illustrating a particular aspect of programming. The tool provides a simulated map of the computer's memory, showing where pointers and variables are stored. The map is dynamically updated as the program is executed. Explanatory notes for each step are provided. The program's function stack may be viewed. At present, the tool can only deal with syntactically correct C code. The package may be used at http://alife.mic.dundee.ac.uk/growe/VINCE/tutorial01.html     

Eliciting and developing student's schema of classroom practices using a video-disc system

In this paper we explore the potential of videodisc technology to develop student teachers'capacity to examine their judgements and reasoning critically about typical classroom events. We describe how the type of setting for such activities is committed to and successful at provoking quality collaborative learning. The videodisc system offers a range of exemplars of teaching which are carefully managed to challenge and extend students'existing ideas. We have adapted the key learning constructs of scaffolding and modelling of various strategies so that the intellectual processes of analysis and reconstruction are persistently attended to. In this way, we are designing a more powerful learning environment to support students in acquiring professionally relevant knowledge.     

Relationships Between Teaching and Research in Higher Education in England

Although there is a popular conception that research enhances teaching, evidence of such synergistic relationships is inconclusive. Recent research, undertaken as part of the Higher Education Funding Council for England's (HEFCE) fundamental review of research policy and funding, indicated that there are a range of relationships – both positive and negative – between teaching and research. While the ideal relationship might be perceived by many academics to be a positive one, there are a number of factors that shape the ways in which teaching and research can have a negative influence on each other, or even be driven apart. These factors include pressures to compartmentalize teaching and research through accountability and funding mechanisms, management strategies of academic staff time that treat teaching and research separately, and the competition for scarce resources. If teaching and research are to complement each other, new ways of managing the teaching and research relationship need to be considered.     

Effect of high-intensity interval training in adolescents with asthma: The eXercise for Asthma with Commando Joe's® (X4ACJ) trial

BackgroundHigher levels of cardiorespiratory fitness are associated with reduced asthma severity and increased quality of life in those with asthma. Therefore, the purpose of this study was to evaluate the effectiveness of a 6-month high-intensity interval training (HIIT) intervention in adolescents with and without asthma.MethodsA total of 616 adolescents (334 boys; 13.0 ± 1.1 years, 1.57 ± 0.10 m, 52.6 ± 12.9 kg, mean ± SD), including 155 with asthma (78 boys), were recruited as part of a randomized controlled trial from 5 schools (4 control and 1 intervention). The 221 intervention participants (116 boys; 47 asthma) completed 6 months of school-based HIIT (30 min, 3 times per week, 10–30 s bouts at >90% age-predicted maximum heart rate with equal rest). At baseline, mid-intervention, post-intervention, and 3-month follow-up, measurements for 20-m shuttle run, body mass index (BMI), lung function, Pediatric Quality of Life Inventory, Paediatric Asthma Quality of Life Questionnaire, and Asthma Control Questionnaire were collected. Additionally, 69 adolescents (39 boys (of the 36 with asthma there were 21 boys)) also completed an incremental ramp test. For analysis, each group''s data (intervention and control) were divided into those with and without asthma.ResultsParticipants with asthma did not differ from their peers in any parameter of aerobic fitness, at any time-point, but were characterized by a greater BMI. The intervention elicited a significant improvement in maximal aerobic fitness but no change in sub-maximal parameters of aerobic fitness, lung function, or quality of life irrespective of asthma status. Those in the intervention group maintained their BMI, whereas BMI significantly increased in the control group throughout the 6-month period.ConclusionHIIT represents an effective tool for improving aerobic fitness and maintaining BMI in adolescents, irrespective of asthma status. HIIT was well-tolerated by those with asthma, who evidenced a similar aerobic fitness to their healthy peers and responded equally well to a HIIT program.     

Conceptualising Curriculum Change

Recent developments in UK higher education are turning attention to the undergraduate curriculum. Drawing on Lyotard's concept of performativity, this paper explores broad patterns of curriculum change in five subject areas. The curriculum is understood as an educational project forming identities founded in three domains: knowledge, action and self. Curriculum models are proposed that identify these components and their relationships with each other. The evidence suggests that the weightings and levels of integration of these components vary between the sciences and technology subjects, the arts and humanities, and professional courses. Attempts to develop curriculum strategies should take account of the patterns of curriculum components as they vary between the subject areas.     

Exploring opportunities available and perceived barriers to physical activity engagement in children and young people with Down syndrome

Primary objective: The aim of this study was to explore physical activity (PA) amongst children and young people with Down syndrome (DS). Method and procedures: The youth physical activity promotion model (YPAP) was used to inform semi-structured interviews to explore PA of children and young people with DS. Participants were three males and five females, aged between 6 and 21?years (16.38?+?5.04?years (mean?+?SD)) who had been diagnosed with the condition DS. Dyadic interviews were conducted with the participant and their parent(s). The interviews were recorded and transcribed, and inductive and deductive analyses of the data were completed. Main outcomes and results: The results were structured around the YPAP Model’s key themes included: enabling factors (seasonal variation, transport, type of activity and independence); predisposing factors (enjoyment, social interaction, dislikes of PA, following instructions, and understanding of PA); reinforcing factors (support and opportunities, parents, and care providers); and barriers to PA engagement (ear problems). Conclusion: The children and young people with DS in the study typically only engaged in fun, unstructured activities. Key facilitators for PA participation were social interactions and parental support. Increasing the level of independence for people with DS within adolescence may have beneficial effects for PA participation in later life.     

John F. Kennedy at American University: The Rhetoric of the Possible,Epideictic Progression,and the Commencement of Peace

In his American University address, Kennedy employed epideictic progression, a pedagogical process drawing upon dissociation and epideictic norms to convince listeners, gradually, to embrace a new vision—in this case, a world in which a test-ban treaty with the U.S.S.R. was possible. To do so, Kennedy's words: (1) united the audience behind the value of “genuine peace”; (2) humanized the Soviets as worthy partners in genuine peace; (3) established the reality of the Cold War and the credibility of U.S. leadership; and (4) connected lessons on genuine peace to domestic civil rights.     

The 'Conveyor Belt Effect': A re-assessment of the impact of National Targets for Lifelong Learning

Although the National Targets for Education and Training in England and Wales include indicators for lifelong learning, and the progress towards the targets set for these indicators has been lauded by politicians and other observers, much of this apparent progress is actually accounted for by changes in these same indicators at Foundation level. However, once the 'conveyor belt effect', of passing increasingly qualified 16-18 year-olds into the working-age population instead of less qualified 60 and 65 year-olds, is taken into account, then progress in qualifying those of working-age is much less. In fact, there is then very limited evidence that Lifelong Learning targets have had any impact at all. Certainly work-based training has not increased, and may even have declined over the last decade, while some socio-economic inequalities in adult participation in education and training have worsened. The paper examines this apparent weakness for the current approach and its implications for the measurement of progress, in the light of a research review carried out for the National Assembly of Wales. It therefore asks increasingly important questions about targets, such as what they are for, and whether those who set and monitor them are aware of their deficiencies and artificialities.     

Joint kinetic determinants of starting block performance in athletic sprinting

The aim of this study was to explore the relationships between lower limb joint kinetics, external force production and starting block performance (normalised average horizontal power, NAHP). Seventeen male sprinters (100 m PB, 10.67 ± 0.32 s) performed maximal block starts from instrumented starting blocks (1000 Hz) whilst 3D kinematics (250 Hz) were also recorded during the block phase. Ankle, knee and hip resultant joint moment and power were calculated at the rear and front leg using inverse dynamics. Average horizontal force applied to the front (r = 0.46) and rear (r = 0.44) block explained 86% of the variance in NAHP. At the joint level, many “very likely” to “almost certain” relationships (r = 0.57 to 0.83) were found between joint kinetic data and the magnitude of horizontal force applied to each block although stepwise multiple regression revealed that 55% of the variance in NAHP was accounted for by rear ankle moment, front hip moment and front knee power. The current study provides novel insight into starting block performance and the relationships between lower limb joint kinetic and external kinetic data that can help inform physical and technical training practices for this skill.
