在教学实践以及学习活动的过程中,不管是什么科目,都会或多或少地发生某些错误。在过去,学生只要一出现错误,教师马上就会发火或者大声地训斥学生,导致学生集体噤声,不敢发言、不敢犯错,将错误遮遮掩掩,造成更大的错误。所以,现在的数学教师需提高学生主体地位,给予学生更多的尊重,与学生的认知规律以及教学的规律相结合,有效利用错误资源,使学生重新认识其所出现错误的原因,进而引发思考。主要说明了利用典型错误资源,引导学生暴露错误以及培养学生的模型意识等有效利用错误资源进行数学习题教学的方法。
In teaching practice and learning activities, no matter what the subject, will be more or less some errors. In the past, whenever a student made a mistake, the teacher immediately became angry or shouted loudly at the students. As a result, the students collectively shout, afraid to speak, afraid to make mistakes, and concealed the mistakes and made even bigger mistakes. Therefore, today’s mathematics teachers need to improve students ’subjective position, give more respect to students, combine with students’ cognitive rules and teaching rules, make effective use of erroneous resources so that students can re-understand the reasons for their mistakes and then trigger Thinking. It mainly explains how to make the best use of the wrong resources, such as using typical wrong resources, guiding students to expose mistakes and cultivating students’ model awareness, to carry out the teaching of mathematical exercises.
