初中教师在授课过程中应当灵活运用新型教学模式,不断拓展学生思维,加大学生思维密度。“问题解决”课堂教学模式的应用可以促使学生们在遇到数学问题时全面的、多层次的分析和思考问题,增加数学课堂的趣味性,培养学生自主独立学习的习惯。“问题解决”教学模式实质上是一个发现问题、展示问题、探究问题、解决问题、遗留问题的完整过程,以下对“问题解决”教学模式的课堂实践进行探讨。以初中数学知识分式方程为例:教师在黑板上写下以 Junior high school teachers in the teaching process should be flexible use of new teaching models, and constantly expand student thinking, increase students’ thinking density. “Problem solving ” The application of classroom teaching mode can promote students in the face of mathematical problems comprehensive and multi-level analysis and thinking problems, increase the interest of mathematics classrooms, develop students’ habits of independent learning. “Problem solving ” teaching mode is essentially a complete process of discovering problems, revealing problems, exploring problems, solving problems and leaving problems. The following discusses the classroom practice of “problem solving ” teaching mode. Take junior middle school mathematics knowledge fractional equation as an example: the teacher writes on the blackboard
