Interaction between television and child-related characteristics as demonstrated by eye movement research

Do field independent individuals and good readers exhibit more proficient scanning strategies than field dependents and poor readers? This study sought to answer those questions as well as to determine whether a dynamic rather than a static presentation leads to better scanning techniques. Measurements of the eye movements of third grade chi Idren as they viewed segments of The Electric Company television program were analyzed in terms of time taken to orient to target, percentage of fixations on target, percentage of time on target, direction of attack, and duration of fixation on target.     

Academic integrity in web based distance education

Conclusion This paper has identified a major gap in the research revolving around academic integrity/dishonesty and WBDE. Statistical evidence and empirical data are almost nonexistent. However, the evidence and data that do exist, strongly challenge many widespread assumptions related to the lack of integrity and the widespread dishonesty that are assumed to exist in WBDE today. Considering the continuing unprecedented growth of distance education, the extremely limited amount of statistical data available on this topic and the implications associated with the (possibly incorrect) assumptions of academic integrity in this environment, it seems that there is a critical need for further study. In the meantime, educational institutions can feel confident about the academic security of their WBDE programs by implementing the few safeguards suggested in this article to protect against dishonesty     

ICT,educational technology and educational instruments. Will what has worked work again elsewhere in the future?

Computers in education have been around for more than 30 years. They have been the vector not only of diverse forms of educational technology, but also of many new kinds of learning activities using software instruments. With the gradual trivialization of computer systems, the initially rather positive expectations about computers in education have progressively turned into more skeptical attitudes about the use of ICT. What is really working with computers in education? Was the investment worth the outcomes? The number of scientific studies focusing on these issues is huge. Most of their results have been obtained either by very focused experiments on some educational technology, generally involving a limited number of students, or by surveys, taking into account large numbers of learners but with little control about the kind of activities that were actually organized. Overall, hardly any conclusive results about possible causal implications of using ICT in learning have been obtained and there is no evidence about the stability of existing results over time. This paper, particularly taking into account the French experience, draws attention on the specific case of software instruments. These instruments do not exactly aim at performing more efficiently existing activities, but lead to invent new learning activities better in line with constructivist views. It suggests that, besides studies about what works, more research is in order about how it works and contends that what will work in the future is linked to the capability of the teaching profession and their allies to collectively build and discuss new interrogations and solutions to pedagogical problems, which will sustain and regulate the many discoveries of innovators.     

The influence of variable resistance moment arm on knee extensor performance

Abstract

To enhance muscular strength, resistance training machines with a cam, incorporating a variable resistance moment arm, are widely used. However, little information is available about the influence of the variable resistance moment arm on torque, velocity, and power during muscle contraction. To address this, a knee extensor machine was equipped with a cam or with a semi-circular pulley that imposed a variable or a constant resistance moment arm, respectively. Fourteen physically active men performed two full knee extensions against loads of 40–80 kg in both conditions. Participants developed significantly higher torque with the pulley than with the cam (P < 0.001). The relative differences between pulley and cam conditions across all loads ranged from 8.72% to 19.87% (P < 0.001). Average knee extension velocity was significantly higher in the cam condition than in the pulley condition. No differences were observed in average and peak power, except at 50 and 55 kg. Torque–velocity and power–velocity relationships were modified when the resistance moment arm was changed. In conclusion, whatever the link, namely cam or pulley, the participants produced similar power at each load. However, the torque–velocity and power–velocity relationships were different in the cam and pulley conditions. The results further suggest that the influence of the machine's mechanism on muscular performance has to be known when prescribing resistance exercises.     

Student engagement: rhetoric and reality

Recently, there has been much interest in higher education literature and policy on the concepts of student engagement and disengagement. While most academic writings recognise the significance of student engagement, they have tended to concentrate on it in relation to academic activities. Increasingly, universities are ‘cascading’ down the need to improve student engagement to schools and ultimately to individual academics. This article asserts that ideas about student engagement in the university context are often fragmented, contradictory and confused. Even the meaning of the term ‘student engagement’ is uncertain. Further, while government and universities urge attention to student engagement, many of their actions, it may be argued, have contributed to greater student disengagement. Relying on the available literature, we argue that the student experience as a whole is the key to engagement and, thus, efforts to re-engage students cannot be successful until a ‘whole-of-university’ approach is adopted.     

OBE: Some Answers for the Uninitiated

In this article, leaders of the North Carolina Writing Project explore whether students of teachers who attended Writing Project summer institutes out-performed other teachers' students on state writing tests. The authors accordingly developed a test to compare the writing of those students with the writing of students of non-writing project teachers. The test, however, produced no significant difference in the writing of the two groups. Seventeen years later, the authors compared the longevity of writing project teachers with that of comparable non-writing project teachers to see if the institutes infused a spirit of professionalism and self-efficacy in participants that other teachers did not possess. This comparison affirmed the authors' beliefs: writing project teachers had greater staying power than comparable teachers.
