"遗传学"课程的教学,首先要注意教学内容的选择,既要介绍遗传学的基本规律、基本理论、基本概念和基本方法,也要介绍遗传学的最新发展成就,以及它对国家政治、经济、文化生活及其他科学技术发展的影响;其次要重视教学方法的使用,既要使用多媒体技术,也可引入建构主义教学法、兴趣教学法等新的教学方法,以提高教学效果. 相似文献

Models are often used when teaching science. In this paper historical models and students’ ideas about genetics are compared.
The historical development of the scientific idea of the gene and its function is described and categorized into five historical
models of gene function. Differences and similarities between these historical models are made explicit. Internal and external
consistency problems between the models are identified and discussed. From the consistency analysis seven epistemological
features are identified. The features vary in such ways between the historical models that it is claimed that learning difficulties
might be the consequence if these features are not explicitly addressed when teaching genetics. Students’ understanding of
genetics, as described in science education literature, is then examined. The comparison shows extensive parallelism between
students’ alternative understanding of genetics and the epistemological features, i.e., the claim is strengthened. It is also
argued that, when teaching gene function, the outlined historical models could be useful in a combined nature of science and
history of science approach. Our findings also raise the question what to teach in relation to preferred learning outcomes
in genetics. 相似文献

Research in genetics and genomics is advancing at a fast pace, and thus keeping up with the most recent findings and conclusions can be very challenging. At the same time these recent findings and conclusions have made necessary a reconceptualization of genes and heredity, both in science and in science education, beyond the mostly gene-centred view of the twentieth century. The teaching of genetics at schools should have a key role in helping students achieve genetics literacy. However, the literature on research in genetics education reports persistent difficulties and misunderstandings. We first consider the public understanding of and the attitudes towards genetics. Then, we review the most recent literature and present the most typical conceptions found among secondary students in various countries, ages and backgrounds. We argue that particular factors such as intuitive thinking, teachers, textbooks, and the media affect students’ development of erroneous or outdated ideas related to genetics. Finally, we suggest how these problems might be addressed in order for genetics teaching at the secondary level to fulfil the aim of contributing to students’ genetics literacy in the current post-genomic era. 相似文献

Teachers have a crucial role to play in raising future generations of citizens who are aware of issues in genetics literacy such as gene therapy, cloning, and stem cell research. Teachers’ teaching practices are influenced by their knowledge in genetics literacy and their attitudes towards different issues. Accordingly, this study explored the relationships among middle school science teachers’ background characteristics (gender, teaching experience, self-perceived interest in and self-perceived knowledge of genetics), their genetics literacy levels, their attitudes towards various issues in genetics literacy, and their perceptions of teaching issues in genetics literacy. Data were collected from 435 Turkish middle school science teachers by completing the Genetics Literacy Assessment Inventory, the scale for attitudes towards issues in genetics literacy and perceptions of teaching issues in genetics literacy. The results of canonical correlation analysis suggested that being female, having a high level of interest in genetics, and perceiving oneself as knowledgeable in genetics were associated with higher levels of knowledge in genetics literacy and holding favorable general attitudes. These teachers believed in the necessity of introducing genetics literacy and held higher self-efficacy teaching beliefs regarding the teaching of issues in genetics literacy in their classes. However, they tended to emphasize more impeding factors as well as hold unfavorable attitudes towards gene therapy and gene therapy applications, implying that their attitudes were context dependent. 相似文献

While genetics has remained as one key topic in school science, it continues to be conceptually and linguistically difficult for students with the concomitant debates as to what should be taught in the age of biotechnology. This article documents the development and implementation of a two‐tier multiple‐choice instrument for diagnosing grades 10 and 12 students’ understanding of genetics in terms of reasoning. The pretest and posttest forms of the diagnostic instrument were used alongside other methods in evaluating students’ understanding of genetics in a case‐based qualitative study on teaching and learning with multiple representations in three Western Australian secondary schools. Previous studies have shown that a two‐tier diagnostic instrument is useful in probing students’ understanding or misunderstanding of scientific concepts and ideas. The diagnostic instrument in this study was designed and then progressively refined, improved, and implemented to evaluate student understanding of genetics in three case schools. The final version of the instrument had Cronbach’s alpha reliability of 0.75 and 0.64, respectively, for its pretest and the posttest forms when it was administered to a group of grade 12 students (n = 17). This two‐tier diagnostic instrument complemented other qualitative data collection methods in this research in generating a more holistic picture of student conceptual learning of genetics in terms of scientific reasoning. Implications of the findings of this study using the diagnostic instrument are discussed. 相似文献
