今年第8期,本刊发表课例《不等式的性质(第3课时)》,让读者点评,至截稿日(9月30日),共收到来自全国16个省市的点评稿40余篇.参与点评的作者既有中学一线教师、教研员,又有大学教授和专业研究工作者;点评多视角、多层面,既评成功,又点缺憾,比较全面和客观.限于版面,我们选择了有代表性的部分来稿全文刊发,有些文稿仅选择其中的部分内容摘登,共分两期连载,以飨读者.“课例点评”是大家非常喜爱和关注的一个栏目,为进一步办好该栏目,首先需要富有点评价值(典型性、研究性、启发性)的课例,欢迎大家继续荐稿、投稿. In the 8th issue of this year, this publication published the lesson class “The Nature of Inequality (3rd Class Hours)” to let readers comment to the deadline (September 30th), and received more than 40 reviews from 16 provinces and cities across the country. The authors who participated in the review included both middle school teachers, professors, university professors, and professional research workers. They commented on multiple perspectives and multi-levels. They both commented on success, but also lacked regrets. They were comprehensive and objective. A representative section of the manuscript was published in full. Some of the manuscripts only selected part of the content and were excerpted. They were divided into two periods for readers to read. “Classification commentary” is a column that we love and concern. Columns, first of all need to be rich in commentary value (typical, research, enlightening) lesson examples, welcome everyone to continue to recommend, submit.
