Hudson and Rottman (1981) established that mathematics ability is probably a secondary factor influencing dropout from college physics courses. Other factors remain to be found for predicting who will drop out or at least have difficulty with the course. When mathematics ability is coupled with general indicators of performance (total GPA and ACT natural science), prediction of performance for those who complete the course is substantially improved. Moreover, discriminant analyses reveal who will have at least some difficulty, but not who will drop out. The problem of isolating specific weaknesses of students who have difficulty persists. Physics achievement appears to depend on mathematics ability only to the extent that students possess the ability to utilize mathematics knowledge for solving physics problems. Identification of the specific aspects of this ability as well as the specific deficiencies leading to dropout should be the object of future research. For the present, interviews might be more revealing than group testing methods. 相似文献

Summary In this article, an attempt has been made to treat affection and cognition “transactionally” and to report work underway in
the development of a rationale for mapping “sign components” of “cultural space.” The development of statistical procedures
and applications remains to be undertaken. 相似文献

Casual games are everywhere. People play them throughout life to pass the time, to engage in social interactions, and to learn. However, their simplicity and use in distraction-heavy environments can attenuate their potential for learning. This experimental study explored the effects playing an online, casual game has on awareness of human biological systems. Two hundred and forty-two children were given pretests at a Museum and posttests at home after playing either a treatment or control game. Also, 41 children were interviewed to explore deeper meanings behind the test results. Results show modest improvement in scientific attitudes, ability to identify human biological systems and in the children’s ability to describe how those systems work together in real-world scenarios. Interviews reveal that children drew upon their prior school learning as they played the game. Also, on the surface they perceived the game as mainly entertainment but were easily able to discern learning outcomes when prompted. Implications for the design of casual games and how they can be used to enhance transfer of knowledge from the classroom to everyday life are discussed. 相似文献

The Durkheimian concept of the density of social relationships may prove more fruitful than the historical materialist notion
of a social hierarchy for thinking about the social location of epistemic agents in science. To define a scientist’s social
location in terms of the density of her professional relationships with other scientists permits us to give a more precise
characterization of marginalization and thus to formulate more testable hypotheses about marginalized groups in science. The
notion of social density helps to explain not only how some individual scientists are more likely than others to get a hearing
for their ideas, but also how scientific inquiry flourishes more in some societies than in others.

Two groups of kittens received 0 or 112 overtraining trials after learning a brightness discrimination. Both groups underwent extinction of differential choice responses and then learned the reversed brightness discrimination. The overtrained and nonovertrained animals did not differ significantly in rate of reversal learning, and both groups showed a significant preference for the old positive stimulus when differential reinforcement was reinstated in reversal training. According to Sutherland and Mackintosh, these results show that kittens lack stable attention and should be inept in dealing with reversal and probability problems. This is not the case, raising doubts about the adequacy of their account of interspecies differences in learning by vertebrates. 相似文献
