The aims of this study were to investigate the effects of discrepancies between teachers' perceptions of students' motivation and students' reports of their motivation on math and English grades and to identify possible gender and ethnic differences. Participants included 215 low-income, ethnic-minority students and their teachers in academically struggling schools. Discrepancy in motivation ratings accounted for a significant amount of variation in final grades. This teacher-student discrepancy effect was larger than both the effect of students' recent standardized test scores and the effect of self-efficacy in both subjects. Girls were found to attract positive teacher bias, but their grades were not differentially affected. Differences in teacher-student discrepancy effects between African American and Latino students were not found. 相似文献

ABSTRACTUniversities seek to promote entrepreneurship through effective education approaches, which need to be in permanent evolution. Nevertheless, the literature in entrepreneurship education lacks empirical evidence. This article discusses relevant issues related to promoting entrepreneurship in the software field, based on the experience of a 15-European Credit Transfer and Accumulation System course. This course seeks to instil in the students the recognition of the need to reconcile technical and business visions, organisational and commercial aspects, most of which have never been addressed previously. A series of semi-structured interviews made it possible to obtain relevant insights about the teaching–learning process underlying this course and its evolution over a seven-year period. Materials related with this course have been analysed, namely guidelines produced by the teachers and deliverables produced by the students. This article discusses the dimensions that were identified as fundamental for promoting entrepreneurship skills in the field of software, namely teamwork, project engagement, and contact with the market. 相似文献

This research suggests that learning biology in an outdoor environment has a positive cognitive and affective impact on 13–15-year-old, Swedish high school pupils. Eighty-five pupils in four classes participated in a quasi-experimental design. Half the pupils, taking a biology course in ecology or diversity of life, had several lessons outdoors and the other half were taught indoors. All of the classes, but one, also had mathematics lessons outdoors once a week. Twenty-one pupils were interviewed five months after the course and all were positive towards the new learning environment they had experienced outdoors in biology and/or mathematics. They also valued the higher degree of interaction among the pupils. Other findings from the interviews were that the pupils from the outdoor classes showed a higher degree of long-term knowledge retention. They remembered both activities and contents better than the pupils in the indoor classes. An essay-type question assessing their biological understanding qualitatively according to the Structure of Observed Learning Outcome taxonomy revealed no differences between the groups. The results are discussed in the light of neurocognitive models of long-term memory. 相似文献

In the last few years an increasing number of researchers has started to investigate children’s conceptions of the economic world. However, complex notions, such as those concerning the overall functioning of an economic system, have hardly been considered. In post-elementary schools children encounter some of these notions in history, geography or social studies. An investigation on this topic should therefore consider both children’s conceptions and misconceptions and the relevant information furnished at school. The present study examines how 7th graders understand two complex economic notions: capitalism and socialism. Two groups of children (N =40) were interviewed, one who had studied a geography textbook containing a large quantity of relevant information, the other one a more traditional book in which these notions were only touched on. The interview was about:
- the characteristics of capitalist and socialist system;
- how it is decided what to produce, and at what prices to sell goods in each of these systems.

Recent research, concerning the application of high-frequency cold plasma in restoration and preservation of the cultural heritage, has included the objects derived from organic materials, which are highly sensitive to microclimate factors. Historical photographs made on paper base and covered with various emulsions belong to this category of heritage objects, and make the purpose of the present study. Plasma treatment was used to enhance the aesthetic aspect of the photographs by a cleaning treatment involving either physical and/or chemical etching, which did not cause major physicochemical changes on the plasma-treated surface. The photographs before and after plasma treatments were analysed by optical and atomic force microscopy, scanning electron microscopy with energy-dispersive X-ray microanalysis, Fourier transform infrared spectroscopy, colour, gloss and contact angle measurements. 相似文献
