随着国家明令禁止补课,减轻学生课业负担的呼声越来越高,如何在有效的时间内提高教学质量成为当前的首要任务。在农村初中化学课堂教学中,教师既要面对有限的资源,又要高质量地完成教学任务,让学生的学习潜能得到充分发挥,培养他们灵活运用化学知识独立解决问题的能力。要向有限的教育资源要质量,向40分钟要质量,课堂教学必须高效。 With the state banning overtaking classes and alleviating students’ burden on their homework, voices are getting louder and louder, and how to improve the quality of teaching in an effective time has become the top priority. In rural junior high school chemistry classroom teaching, teachers should not only face the limited resources, but also complete the teaching tasks with high quality, so as to give full play to their learning potentials and cultivate their ability of using chemical knowledge to solve problems independently. To the quality of limited educational resources to 40 minutes to quality, classroom teaching must be efficient.
