一、创设情境,激发兴趣 教师通过创设教学情境,激发学生的学习兴趣和学习热情,使学生情感卷入认识对象,就能充分调动学生思维的积极性,达到自觉参与并主动学习。这是自然教学成功的首要环节。要激发学生的学习兴趣,教师要创造一个宽松、和谐、平等的课堂气氛,放手让学观察、实验、思考,让具体的自然事物、有趣的自然现象紧紧吸引学生,产生强烈的求知欲望。 比如《怎样加快溶解》的教学中,教师出示一块红糖,然后提出贴近学生生活实际且富有激发思维的问题:“要把这块红糖尽快溶解成一杯红糖水,应该怎么做?”。学生对这一问题既有知识基础,又有生活经验,但却又是一个面临的新问题,因而必然出现抢着回答的局面。
First, the creation of situations to stimulate interest Teachers through the creation of teaching situations, to stimulate students interest in learning and enthusiasm for learning, so that students' emotions into the cognitive object, we can fully mobilize the enthusiasm of students thinking to achieve voluntary participation and take the initiative to learn. This is the first step in the success of natural teaching. To stimulate students' interest in learning, teachers should create a relaxed, harmonious and equal classroom atmosphere and let them observe, experiment and think so that specific natural things and interesting natural phenomena can attract students and generate a strong desire for knowledge. Such as “how to speed up the dissolution of” teaching, teachers produce a piece of brown sugar, and then put forward close to the actual student life and full of exciting thinking: “to dissolve the brown sugar as soon as possible into a cup of brown sugar, what should I do ?.” Students have both a knowledge base and a life experience on this issue, but they are still facing new problems. Therefore, they will inevitably emerge as rushing answers.
