在化学教学中经常出现重教轻学,学生被动学习、效率低、能力差的问题以及教师的主导作用与学生的主体作用脱节的现象。只有进行新的教学尝试,注重对学生创新能力、自学能力以及实践能力的培养,才能有效地提高初中化学教学的质量。一、课前准备是基础。教师课前给出学生课题,让学生提前预习,明确要探究的目标。如在学习化学新教材第一章“开启化学之门”的第一课之前,先列了一些提纲,由 In chemistry teaching, there often appear the phenomenon of re-education, passive learning, low efficiency and poor ability, as well as the fact that the dominant role of teachers and the subject function of students are out of line. Only by doing new teaching and trying to cultivate the students’ ability of innovation, self-learning and practical ability can the quality of junior high school chemistry teaching be effectively improved. First, pre-class preparation is the foundation. Teachers give students a lesson before class, so that students preview in advance, a clear goal to explore. As in the first chapter of the first chapter of learning chemistry new teaching materials “open the door of chemistry ”, the first outlines some of the outline from
