小学低年级数学《除数是两位数除法》虽说起步简单,却也障碍重重,要是搬书宣读,不探求规律,不寻找突破口,学生往往感到迷茫,望题生畏。在高效课堂的渗透中,教师必须吃透教材,寻找固有的规律,跨越教学的鸿沟,使学生在较短时间内收效最高。 Although the simple start-up, but also obstacles, if moved to read the book, not to explore the law, do not look for a breakthrough, the students are often confused and hopeless. In the infiltration of efficient classrooms, teachers must thoroughly understand teaching materials, look for inherent laws and bridge the gap between teaching so that students will achieve the highest results in a relatively short period of time.
