在课堂教学中,数学教师已较多地应用变式教学,对变式教学认可度也较高。由于对变式教学实质的理解认识,某些数学教师存在一定的偏差,因而变式教学的实际应用也就因人而异.我们如果仔细研究认真领会变式教学的要义,就能使变式教学在课堂教学中获得高效运用.我们还需要在尊重学生主体的基础上,明确教学课堂目标,调整变异空间和变异梯度,才能实现有效的创新教学。 In classroom teaching, mathematics teachers have been more use of variant teaching, teaching variant teaching is also higher. Due to the understanding of the essence of variant teaching, some math teachers have some deviations, so the practical application of variant teaching also varies from person to person.If we carefully study and carefully understand the meaning of variant teaching, we can make the variant Teaching in classroom teaching to obtain efficient use.We also need to respect the student subject, based on clear teaching objectives, adjust the variation space and mutation gradient, in order to achieve effective innovation teaching.
