听课是教学研究的主要方式之一。传统的听课,随意性大,评课主观,很容易走“自我”。如此的听课大多停留在经验层面,缺乏研究意识,对课的研究深度不够。评课者经验不同,关注点不同,看课就不一样。上课者最后听听这个有理,想想那个有理,一堂课被填鸭式地点评,问题难以聚焦,研究难以深入。因此,听评课成了没有依据,没有聚焦,走个过场的状态。听课选择个案研究的思路和方法,能帮助听课者聚焦问题,让研究走向纵深。听课中,如何开展个案研究呢?笔者采用了从学生的“学”出发、观察学生的学的“四点打桩法”。一、打桩采样,指向学生 Teaching is one of the main ways of teaching and research. Traditional lectures, arbitrary, class subjective, it is easy to go “self ”. Most of such lectures stay in the empirical level, lack of research awareness, the depth of the study of the class is not enough. Lessons have different experiences, different points of interest, not the same class. Last class listeners to listen to this rational, think that is reasonable, a class was spoon-fed venue, the problem is difficult to focus on the research difficult to in-depth. Therefore, listening to assessment class has no basis, no focus, take a state of the scene. Listening to choose the case study ideas and methods that can help participants focus on issues, so that research in depth. In the lectures, how to carry out the case study? I used from the students “learning ” starting to observe the students “four piling method ”. First, piling sampling, point to students
