沪港澳中学数学课堂的主要共性有:指令性讲解为主;较为重视课堂练习;强调问题之间的内在联系;强调讲清概念;强调对算法的讲解、练习以及总结.主要差异有:上海课堂的效率最高,并有一定时间为学生提供探究性学习的机会;香港课堂练习时间最多,但练习的问题中,重复性和低复杂性的问题最多;澳门课堂练习时间最少,而练习的问题复杂性较高等.

Looking into Mathematics Classroom Teaching in Hong Kong,Macau and Shanghai

Based on a fine-grained analysis of 45 video taped lessons from Hong Kong,Macau and Shanghai,the following similarities among them were found: directive talk domination,emphasis on classroom exercise,emphasis on the inter connection of problems,emphasis on explanation of concept and procedure directly and clearly,and consolidation of them by exercise and summary.Meanwhile,some subtle differences were observed as follows.The Shanghai teachers were very effective in using of lesson time,and offer certain exploratory opportunities for their students.The Hong Kong teachers spend majority of classroom time on practicing with repetition and low complexity problems,while the Macau teachers spend least time on practicing,but with the highest percentage of high complexity problems.Finally,the pedagogical implications of these findings were discussed..
