在教学过程中,要更新教学理念,要俯下身去,走进学生的生活,走进孩子的心灵世界,激发他们的主体意识,用他们喜欢的方式去遭遇数学问题,去喜欢数学问题。因为充分利用学生的生活经验,能更好地理解和掌握抽象的数学概念和知识。如《时、分、秒》的教学中,时间的概念是抽象的,我设计了这样的一个教学活动:“一分钟的价值”。我提出了这样的问题:一分钟你能干些什么?让孩子带着这个问题,让他们自己去体验。我让他们写字、读课文、跳绳、背古诗等。结果,他们得出了结论:一分钟能写5个词语,一分钟读两小自然段的课文,一分钟背2首古诗……这样不
In the process of teaching, to update the teaching philosophy, we must step down, into the student life, into the child’s spiritual world, to stimulate their subjective consciousness, in the way they like to encounter mathematical problems, to like math problems. Because you make good use of the student’s life experience, you can better understand and master abstract mathematical concepts and knowledge. In the teaching of “hour, minute, second”, the concept of time is abstract. I designed such a teaching activity as “one minute worth”. I asked the question: What can you do in a minute? Let the kids take the problem and let them experience it. I let them write, read texts, skipping, ancient poetry and so on. As a result, they came to the conclusion that five words could be written in one minute, two small texts in one minute, two ancient poems in one minute ... so not
