初中化学教学效率的提升,学生学习经验的丰富离不开高频率、高质量的化学练习,学生化学知识能力水平的丰富需要教师在教学中培养学生的学习经验,丰富化学有效练习的教学模式。对初中化学教学目标进行了概述,在此基础上,重点详细论述了初中化学教师应该如何基于学生经验来构建初中化学有效练习的教学模式,从初中化学教学目标的角度出发,将教学目标融入初中化学练习教学模式中,从而增强教师在化学有效练习教学中的效率,增强教师教学有效性和学生学习的有效性。
The efficiency of junior high school chemistry teaching can not be separated from the high frequency and high-quality chemistry exercises. Students ’rich ability of chemical knowledge requires teachers to cultivate students’ learning experience in teaching and enrich the teaching mode of effective chemical practice. On the basis of this, the thesis mainly elaborates on how junior high school chemistry teachers should construct the teaching mode of junior high school chemistry practice based on the students’ experience. From the perspective of junior high school chemistry teaching goal, the teaching goal is integrated into junior high school Chemical practice teaching mode, thereby enhancing the efficiency of teachers in the teaching of chemical effective practice, enhance the effectiveness of teaching and learning and student learning effectiveness.
