教材分析 1.本课内容在教材知识网络中是两条线的汇集点:一条线涉及减数分裂、受精作用、多细胞生物的个体发育过程等知识点;另一条线涉及遗传的基本规律。通过本课学习,学生将获得性别决定与伴性遗传的有关知识,使其“生物遗传”方面的知识体系比较完整了。明确本课在教材知识体系中的地位,有助于确定知识点。 Analysis of Teaching Materials 1. The content of this course is a collection of two lines in the teaching material knowledge network: One line involves knowledge points such as meiosis, fertilization, and the multi-cell organism’s ontogeny; the other line concerns the basic law of inheritance. Through this lesson, students will acquire relevant knowledge of gender determination and genetic inheritance, making their knowledge system of “biological genetics” complete. Defining the position of this lesson in the teaching material knowledge system helps to determine knowledge points.
