推荐理由：本次评课有两个关注点,一是培训七一中学化学教师的评课能力,二是指向化学概念课的教学实践。评课目标本次评课活动采用直接评课方式。选择化学概念教学中的典型课例“物质的量浓度”展开评课,一方面通过课例分析对七一中学高中化学教师的评课能力开展培训,结合静安区化学学科评课要点,在自身观课的基础上,共同研讨并明确两个问题：如何评价化学课堂教学?怎样的化学课是好课?另一方面选择化学基本概念的教学这一化学课堂教学的难点,研讨如何使学生在化学基本概念的学习中,既能生动自主地学习,又能深入理解核心概念。
Recommended reason: There are two concerns in this course. One is to train the teaching ability of chemistry teacher in middle school in July 1st, and the other is to teach in the teaching of chemistry concept. Assessment objectives The assessment activities using direct assessment of class. Select the typical case of chemical concept teaching “concentration of substances” to start the class, on the one hand through the case analysis of the ability to teach high school chemistry teachers in the assessment of the ability to carry out training, combined with the chemical discipline of Jing’an District assessment points, in their own On the basis of observing classes, we discuss and clarify two issues: how to evaluate chemistry classroom teaching, what kind of chemistry class is a good lesson, and on the other hand, to choose the basic concepts of chemistry teaching, the difficulty of chemistry class teaching, how to make students Learn the basic concepts of chemistry, both vivid and self-learning, but also in-depth understanding of the core concepts.
