高效的化学课堂是指以最小的教学和学习投入,以获得最大的课堂效益.所以在高中化学课堂中的有效提问就变得特别重要.有效提问是指教师在精心预设问题的基础上,创设一定的问题情境,在教学过程中生成适当的问题,要引导学生的主动思考和回答,从而全面实现预期的教学目标的过程.准确有效的课堂提问不仅能激发学生的学习兴趣,还能更好地提高教学效率.所以有效问题设计被视为高效课堂教学的核心.在高中化学课堂中,如何进行有效问题的设计呢?下面结合案例,
Efficient chemical classroom refers to the minimum of teaching and learning input, in order to obtain the maximum classroom benefits.Therefore, effective questioning in high school chemistry classroom becomes particularly important.Effective questioning refers to the teacher based on carefully pre-set questions, To create a certain problem situation, to generate appropriate problems in the teaching process, to guide students ’active thinking and answering, so as to fully realize the expected teaching goal process.Efficient and effective classroom questioning can not only stimulate students’ interest in learning, but also more So to improve the efficiency of teaching.Therefore, the effective design of the problem is considered as the core of efficient classroom teaching.In high school chemistry classroom, how to carry out the design of effective problems? The following combination of cases,
