自由组合定律是遗传学的重要定律,也是生物教学的重难点及高考常考知识点,但该定律抽象难懂,学生不易理解。为此,利用烧杯、玻璃珠等材料制作“自由组合定律模拟装置”。学生通过亲手操作该装置,能模拟自由组合定律的过程,可将抽象的问题具体化、直观化,从而加深其对相关概念的理解。 The free combination law is an important law of genetics. It is also a major difficulty in biology teaching and the regular examination knowledge of the college entrance examination. However, the law is abstract and difficult to understand, and students are not easy to understand. For this purpose, “free combination law simulation device” is made of materials such as beakers and glass beads. By operating the device by hand, students can simulate the process of the law of free combination, and can abstract and visualize the abstract problem, thereby deepening their understanding of related concepts.
