新课程实施以来,问题式教学成为课堂教学的主要模式。如何在实际教学中通过设置问题,引导学生层层深入,帮助学生实现从直观到抽象的跨越,最终确立数学概念,突破教学的重点和难点,是问题式教学的关键所在。通过展示一堂示范教学实录,教学过程采用了问题式教学模式,以期和大家共同探讨提高。 Since the implementation of the new curriculum, problem-based teaching has become the main mode of classroom teaching. How to set the question in the actual teaching, guide the students to go deep into layers, help the students to realize the leap from visual to abstract, finally establish the mathematical concepts and break through the key and difficult points of the teaching, which is the crux of the problem-based teaching. Through demonstrating a demonstration teaching record, the teaching process adopted the question-based teaching mode, with a view to discussing and improving with everyone.
