课前预习是学生对下一节课内容的一个前瞻。知识点预习得是否到位,是否深入、透彻将会对下一节课老师讲解的内容能否真正掌握起到决定性的作用。只有坚持把课前预习踏实地做好,才能使课堂更加的高效,让“向45分钟要效率”不再成为空谈。在预习导航模式下,导学案中课前预习内容精心的设计能更好地展现“老师教”和“学生学”的有机统一,更加充分展现出“以学生为主体”的学习氛围,使学生真正地走向课堂教学的前台。 Pre-class preview is a preview of the student’s next lesson. Whether the knowledge point prep is in place, whether in-depth and thorough will play a decisive role in whether the content of the next lesson teacher can really be mastered. Only insist on doing a good job before the class preview, in order to make the classroom more efficient, so that “45 minutes to be efficient,” no longer become empty talk. In the preview navigation mode, the elaborate design of the pre-lesson preview contents in the guide case can better demonstrate the organic unity of “teacher teaching” and “student learning” and more fully demonstrate the “student-centered ”Learning atmosphere, so that students really go to the classroom teaching prospects.
