利用模型构建开展遗传学教学的实践

Practice of using model construction to carry out genetics teaching

在遗传学教学过程中,为了能够将抽象的内容以直观、形象的方式呈现给学生,帮助学生更好地理解遗传学理论知识,从明确任务、合作学习、制作模型、分析模型、完善模型、应用模型六方面将模型构建引入课堂教学.以问题驱动引导学生构建模型,使学生在构建模型的过程中理解遗传学概念,在分析模型中领悟遗传规律的实质,在应用模型中内化遗传学知识,从而提高教学质量,发展学生的科学思维.以“连锁与交换”一节内容为例,讲述遗传学教学过程中开展物理模型构建的具体流程.

content to students in an intuitive and visual manner,help students can thus better understand the theoretical knowledge of genetics,teachers introduce model construction into classroom teaching from arranging clear tasks,cooperative learning,modeling,analyzing model,improving model,applying model six aspects.Guide students to construct models through problem-driven guidance,enable students to understand genetic concepts during the process of constructing models,understand the essence of genetics laws during the process of analyzing models,internalize genetic knowledge during the process of applying models,so then improve the quality of teaching and develop students′scientific thinking in the process.Take the section on linkage and exchange as an example to describe the specific process of physical model construction in genetics teaching.
