This article describes a statistical integration of findings from 74 studies of visualbased college teaching. In the typical
study, students learned slightly more from visual-based instruction than from conventional teaching. In the typical study,
visual-based instruction had no special effect on course completion, student attitudes, or the correlation between aptitude
and achievement. Students were equally likely to complete visual-based and conventional classes; their attitudes toward the
two kinds of classes were very similar; and aptitude played a strong role in determining student achievement in each kind
of class.
This study was supported by National Science Foundation Grant SED 77-18566. 相似文献

This study investigated teachers’ experiences of closeness during interactions with the group of children in child care. Structured interviews were conducted with 24 female teachers who were teaching children between the ages of three and five (mean age = 3.9) regarding their perceptions of closeness with the group of children in the class. Qualitative analyses of the interviews revealed a group solidarity domain of teacher–group relationships composed of three dimensions which comprise emotional solidarity, consensual solidarity, and functional solidarity, with emotional solidarity most dominant in the teachers’ perceptions. This group solidarity domain was interpreted as being consistent with qualities found in Grusec and Davidov’s group participation domain. The findings that, teachers’ closeness with the group of children in the class were dominated by the emotional dimension is similar to previous research results which report the predominance of personal and intimate interactions in relational closeness between teachers and individual children. Teachers described intentional strategies for managing close group relationships that made use of interactional histories between the teachers and children in the class. These discoveries provide a new perspective on teacher closeness with groups, an area of research not often investigated. It also provides insights into the importance teachers place on connecting emotionally with children when they are with the collective group in the classroom. 相似文献

The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture specimen quizzes. The study also determined student performance on insect identification tasks was not as good as for family-level identification as compared to broader insect orders and arthropod classification identification tasks. Finally, students erred significantly more by misidentification than misspelling specimen names on prepared specimen quizzes. Results of this study support that short web-based insect identification exercises can improve insect identification performance. Also included is a discussion of how these results can be used in teaching and future research on biological identification. 相似文献

Israel suffers from a growing problem of socio-economic gaps between those who live in the center of the country and residents of outlying areas. As a result, there is a low level of accessibility to higher education among the peripheral population. The goal of the Sidney Warren Science Education Center for Youth at Tel-Hai College is to strengthen the potential of middle and high school students and encourage them to pursue higher education, with an emphasis on majoring in science and technology. This study investigated the implementation and evaluation of the enrichment science academic program, as an example of informal learning environment, with an emphasis on physics studies. About 500 students conducted feedback survey after participating in science activities in four domains: biology, chemistry, physics, and computer science. Results indicated high level of satisfaction among the students. No differences were found with respect to gender excluding in physics with a positive attitudes advantage among boys. In order to get a deeper understanding of this finding, about 70 additional students conducted special questionnaires, both 1 week before the physics enrichment day and at the end of that day. Questionnaires were intended to assess both their attitudes toward physics and their knowledge and conceptions of the physical concept “pressure.” We found that the activity moderately improved boys’ attitudes toward physics, but that girls displayed decreased interest in and lower self-efficacy toward physics. Research results were used to the improvement of the instructional design of the physics activity demonstrating internal evaluation process for effective intervention. 相似文献
