在美国的初中科学教材中,阅读材料与正文的关系是相辅相成的。阅读材料能使得教材在内容的深度和广度、时间和空间上得到扩展,能渗透科学技术与社会和科学发展史的内容,有利于学生开展研究性学习,所以阅读材料具有使科学教材在内容上综合化、弹性化、补充正文、培养学生的各种能力和激发学生对科学的学习兴趣的功能。其他国家编写科学教材的成功经验对我们有很好的借鉴和启发作用。 相似文献

前苏联著名教育家乌申斯基说过“把画片带进教室,就是哑子也会说话了”,足见图片在教学中的重要作用.教材图片有着丰富多变的艺术形式和表现手法,它与一般的示意图和简化图相比,更加直观、形象、生动,表现事物的物理特征更加突出、鲜明.本文对美国的权威研究性教材《科学探索者》中的插图进行简单的文化分类,与诸位同仁分享. 相似文献

This article describes the development and validation of an instrument that can be used for content analysis of inquiry-based tasks. According to the theories of educational evaluation and qualities of inquiry, four essential functions that inquiry-based tasks should serve are defined: (1) assisting in the construction of understandings about scientific concepts, (2) providing students opportunities to use inquiry process skills, (3) being conducive to establishing understandings about scientific inquiry, and (4) giving students opportunities to develop higher order thinking skills. An instrument – the Inquiry-Based Tasks Analysis Inventory (ITAI) – was developed to judge whether inquiry-based tasks perform these functions well. To test the reliability and validity of the ITAI, 4 faculty members were invited to use the ITAI to collect data from 53 inquiry-based tasks in the 3 most widely adopted senior secondary biology textbooks in Mainland China. The results indicate that (1) the inter-rater reliability reached 87.7%, (2) the grading criteria have high discriminant validity, (3) the items possess high convergent validity, and (4) the Cronbach’s alpha reliability coefficient reached 0.792. The study concludes that the ITAI is valid and reliable. Because of its solid foundations in theoretical and empirical argumentation, the ITAI is trustworthy. 相似文献

This study examined elementary and middle school students' images of science and scientists, with an analysis of how those images may be influenced by science textbooks currently in use in Taiwan. A modified Chambers' Draw-a-Scientist Test (DAST) was administered to a total 289 students from grades 1, 3, 5 and 8. Results showed that upper-grade students drew more indicators (i.e., lab coats, eyeglasses, facial features, research and knowledge symbols, and relevant captions) than did lower-grade students. An analysis of individual drawings revealed an increase in sophistication and complexity according to progressively higher grade levels. It was found that students very often drew images strikingly similar to what their science textbook presented. It implicated that our current science textbooks indeed have some degree of influence on students' image of science and scientists. 相似文献

This article reports on an analysis and comparison of three South African Grade 9 (13–14 years) Natural Sciences textbooks for the representation of nature of science (NOS). The analysis was framed by an analytical tool developed and validated by Abd-El-Khalick and a team of researchers in a large-scale study on the high school textbooks in the USA. The three textbooks were scored on targeted NOS aspects on a scale of ?3 to +3 that reflected the explicitness with which these aspects were addressed. The analysis revealed that the textbooks poorly depict NOS, and in particular, there was scant attention given to the social dimension of science, science versus pseudoscience and the ‘myth of the scientific method’. The findings of this study are incommensurate with the strong emphasis in a reformed school science curriculum that underlies the need for learners to understand the scientific enterprise, and how scientific knowledge develops. In view of this, the findings of this research reinforce the need for a review on the mandate given to textbook publishers and writers so that a stronger focus be placed on the development of materials that better represent the tenets of NOS. 相似文献

Recent studies have shown that the positive emotional design of learning environments might foster learning performance. In contrast, the seductive detail effect postulates that additional, learning irrelevant details inhibit learning. This research focusses on the implementation of decorative pictures as a prime for emotions and context-relatedness. This study examines four groups of decorative pictures which might be conducive for learning. Eighty-two students were randomly assigned to one cell of a 2 (emotionally positive vs. emotionally negative pictures) × 2 (school context vs. leisure context pictures) between-subjects, factorial design. The dimensions of pleasure, arousal, and dominance are examined as possible mediators. Results show that either positively valenced pictures or learning pictures foster retention and transfer performance. Pleasure is identified as mediator of the effect between valence of pictures and learning performance. A further analysis shows differences for arousal and dominance for both factors. These results are interpreted with concepts like motivated attention and other arousal theories. 相似文献

诗味一直为诗歌创作者所追求,"辨味"批评也一直是诗歌欣赏的重要手段。自古至今,学界一直认为:"有趣者好诗,无味者劣诗。"但实际上,食味与诗味既有本质联系,又有所区别。诗味具有超越性特征,同时还具有审美目的。 相似文献
