课例研修是一种以提升教师教学设计能力和打磨优秀课例为主要目标的常见的教师研修形式。为探究课例研修活动效果，文章基于建构主义学习理论和协作学习理论，设计了一种由三轮备课、两轮研讨和两轮授课组成的教师协同课例研修活动，并以“基于AR的初中化学教学设计”为例，采用准实验研究法探究了教师协同课例研修对学生满意度和学习成绩的影响。研究发现：（1）课例研修前，不同教师执教班级的学生满意度存在显著差异，学习成绩不存在显著差异；（2）课例研修后，不同教师执教班级的学生满意度不存在显著差异，学习成绩不存在显著差异；（3）教师协同课例研修有利于提高主讲教师课堂的学生满意度和学习成绩，且课例研修前和课例研修后的学生满意度和学习成绩均存在显著差异。
【英文摘要】：
Lesson study is a common form to improve the ability of teaching design of teachers and to create excellent lessons. In order to explore the effects of lesson study, based on the constructivism learning theory and collaborative learning theory, this paper designs a teacher collaborative lesson study consisting of three rounds of lesson preparations, two rounds of discussions, and two rounds of teaching. Taking "AR-based chemistry instructional design in junior high school" as an example, the quasi-experimental approach is adopted to explore the influence of teachers' collaborative lesson study on students' satisfaction and academic performance. The results indicate that:(1) before the lesson study, there is significant difference in student satisfaction between different classes taught by different teachers, and there is no significant difference in academic performance;(2) after the lesson study, there is no significant difference in student satisfaction and academic performance between different teachers and classes;(3) teachers' collaborative lesson study is conducive to improving student satisfaction and academic performance, and there are significant differences in student satisfaction and academic performance before and after the lesson study.
