“探、导、讲、练”是自主式“学案稿”的主要流程,因此教师要重视学案稿中的“探与导”的设计,为“讲与练”的进行做好铺垫。把数学课堂转变为学生自主探究的实验室,激发学生学习兴趣,让数学学习过程成为一种轻松而快乐的享受。一串好的“探与导”问题设计在实施自主式“学案稿”活动中能使课堂学习的整体效益大大增加。一串好的“探与导”问题设计应重点具备三要素和四性质。 Therefore, teachers should pay more attention to the design of “probe and guide” in the case study so as to “talk and practice” “To do the bedding. The mathematics classroom into students to explore the laboratory, to stimulate students interest in learning, mathematics learning process to become a relaxed and happy to enjoy. A series of good ”exploration and guide“ problem design in the implementation of independent ”case study draft “ activities can make the overall benefit of classroom learning greatly increased. A good series of ”probe and guide" design should focus on three elements and four properties.
