新课改以来“高效课堂”“有效课堂”成为探索课堂模式的根本出发点,尤其是“问题引领式教学”在各种教学模式中占据上风。的确,有效教学的重要指标是学生参与的有效性,有效参与的核心是思维的参与,而问题是思维的先导。我们评价一节课是否有效不在于教师提出的问题多少及教学场面如何热烈,而在于教师提出的问题是否真正引发了学生的思考。 Since the new curriculum reform, “efficient classroom ” “effective classroom ” has become the fundamental starting point to explore the classroom model, especially “lead the way teaching ” prevail in a variety of teaching modes. Indeed, an important indicator of effective teaching is the effectiveness of student participation. The core of effective participation is the participation of thinking, and the problem is the precursor of thinking. We evaluate whether a class is effective or not depends on how many questions the teacher put forward and how warm the teaching scene is, and whether the questions raised by the teacher really arouse the students’ thinking.
