由于编写教材的同志很难想象学生做题时会发生怎样的错误,因而教材中改错练习极少,由于教材中改错练习少,因而教师也就很少让学生做这类练习。就因为这点,不知使教学走了多少弯路!因此,需要响亮提出:把设计改错练习作为教学设计的一项重要内容。 Since it is difficult for a comrade who writes materials to imagine what errors students make when they do the questions, there are very few error-correcting exercises in the teaching materials. Because few error-correcting exercises are used in teaching materials, teachers seldom allow students to do such exercises. Because of this, I do not know how many detours the teaching has taken! Therefore, it is necessary to say loudly that designing error-correcting exercises as an important part of instructional design.
