细胞遗传学综合性实验的设计与实践 总被引：1，自引：0，他引：1
《实验室研究与探索》2019,(9)
将大学生创新训练项目成果与细胞遗传学验证性实验结合,设计一个秋水仙素对洋葱根尖细胞有丝分裂影响的综合性实验。该实验能使学生熟练掌握两项技术和两种方法:生物显微镜操作与有丝分裂制片技术,人工诱导植物染色体变异方法与方差分析法。使学生了解了有丝分裂变化过程、染色体的结构变异和数目变异等特征,与秋水仙素对植物遗传和变异的影响。并在该实验基础上拓展了一个细胞遗传学研究性实验,通过"验证性-综合设计性-创新研究性实验"的多层次、研究性实验教学方式,提升了学生的综合能力、创新能力及研究能力。 相似文献

Contemporary genomics research will impact the daily practice of biology teachers who want to teach up-to-date genetics in secondary education. This article reports on a research project aimed at enhancing biology teachers’ expertise for teaching genetics situated in the context of genetic testing. The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of an educational approach based on situated learning. What expertise do biology teachers need for teaching genetics in the personal health context of genetic testing? This article describes the required expertise by exploring the educational practice. Nine experienced teachers were interviewed about the pedagogical content, moral and interpersonal expertise areas concerning how to teach genetics in the personal health context of genetic testing, and the lessons of five of them were observed. The findings showed that the required teacher expertise encompasses specific pedagogical content expertise, interpersonal expertise and a preference for teacher roles and teaching approaches for the moral aspects of teaching in this context. A need for further development of teaching and learning activities for (reflection on) moral reasoning came to the fore. Suggestions regarding how to apply this expertise into context-based genetics education are discussed. 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

分析了遗传学实验教学中存在的问题,在实际教学中进行改革尝试,采用n＋x的教学新模式：设置n个基本的验证型或综合型大纲内实验,同时增加多个可供学生自主选择甚至设计的大纲外实验——x方案。在保证正常实验教学的同时,克服了学时不足的缺点,同时充分激发了学生的积极性和创造性,有效地推动了遗传学教学的效果。 相似文献
