The greater part of psychoanalytical literature about television as a phenomenon of our century, stresses generally the impressive force of television. It affects the habits of man, determines the rhythm of his life and his attitude towards life. This being so, judgements are preconceived and so man's power of unbiased decision is weakened. Television has a personal intimate style of presentation and effects thus in the viewer a readiness of identification that outstrips by far that of the film experience. 相似文献

This paper outlines the design of a physics textbook that addresses issues of gender-inclusive physics teaching, STS and constructivism.
Difficulties of addressing these issues in a textbook for normal classes, which has to compete with other textbooks on the
market will be discussed.
Specializations: constructivist approaches in science education research and practice.
Specializations: gender issues in science instruction.
Specializations: primary education, integrated science.
Specializations: STS, phenomenological oriented physics instruction.

If children are engaged in science lessons, their learning is likely to be better and, in the long term, careers in science
and technology will remain open. Given that attitudes can develop early and be difficult to change, it is important for teachers
of younger children to know how to foster engagement in science. This study identified what a cohort of 79 pre-service teachers
in England considered to be engaging elementary science lessons and compared their notions with teacher behaviours known to
be conducive to engagement. First, all brought beliefs about how to engage children in science lessons to their training.
They tended to favour children’s hands-on activity as an effective means of fostering attentive participation in learning,
although many had additional ideas. Nevertheless, the means and ends of their ‘pedagogies of engagement’ tended to be simple
and narrow. Trainers need to ensure that notions of engagement are wide enough to cope with a variety of teaching situations,
as when hands-on experience is not feasible, effective or appropriate. At the same time, teachers will need to recognise that
one approach may not suit all learners. Without this, there is the risk that they will lack the skills to engage children
in science. Nevertheless, these beliefs could offer a useful starting point for trainers who wish to widen pre-service teachers’
conceptions of engagement and increase their repertoire of teaching behaviours. 相似文献

AbstractPsychologists and mathematics educators have long viewed flexibility as critical to students’ mathematical development. In this paper, we focused on the multidimensional nature of flexibility to better understand how preference, knowledge, and use of effective methods for solving algebra problems are related. In Study 1, we identified research-based aspects of flexibility with algebra and assessed students on them following a two-step equations unit. Results indicated that certain aspects of flexibility develop prior to others and that prior knowledge of algebra plays a significant role in that development. Study 2 confirmed and elaborated on these results using a larger sample size. Implications for theory and for supporting flexibility in classrooms are discussed. 相似文献

This year marks the centenary of the death of W. H. Fox Talbot, the inventor of the negative/positive process of photography. This article reviews his contribution to the development of photography in relation to that of other pioneers, notably Niépce, Daguerre, and Archer. It also considers the consequences for the development of photography in Britain of Talbot's strict adherence to his patent rights. 相似文献

Interaction of wrestling shoe and competition surface: effects on coefficient of friction with implications for injury 总被引:1,自引:0,他引:1

The purpose of this study was to determine whether there is a significant difference in the co-efficient of friction (Fc) between old versus new wrestling shoes and mats and to investigate the effect of perspiration. Fc was measured by dragging a weighted shoe over a wrestling mat surface and measuring the vertical and horizontal forces produced. Three different shoe conditions were assessed over two mat types for both wet and dry conditions for a total of 12 conditions. To simulate the wet condition, saline solution was smeared over the surface of the mat. There was a significant effect of shoe, mat, and wet/dry conditions. In addition, significant interactions of shoe by mat, shoe by dry/wet, and mat by dry/wet were observed. Overall, Fc was 36% higher for the new wrestling mat compared to the old wrestling mat. Application of the saline solution reduced Fc by 14% compared to the dry condition. Comparison of the mean Fc for all three shoe types revealed the Fc for the older design shoe was 23% to 28% lower than the brand new shoe and the worn newer design, respectively. A high Fc, such as in the new mat/new shoe combination, has the potential to increase the risk of knee and ankle injuries by fixing the foot more securely to the ground. 相似文献
