兴趣是人对客观事物的选择性态度,是积极认识某种事物或参加某种活动的心理倾向。它是学生学习和发展思维的巨大动力。根据儿童好动、好奇,注意力不能持久的特点,我在课堂教学中,采用不同的方法来激发和保持学生的学习兴趣,使他们对教学内容的无意识注意转化为有意识的关注,从而始终都在愉悦的气氛中学习,做到寓教于乐。一、在新课引探中,激发学习兴趣巧设问题,产生疑问,激发兴趣。在教学过程中,我采取不同的设疑方式,做到设疑、激疑,使课堂气氛跌宕起伏。如教学退位减法时,我这样设疑。出示34-6时,提问:“个位上是几减6?”学生答后又问:“4-6不够减?怎么办?”请用学具摆摆看。学生产生疑问,带着疑问去动手操作、寻求答案。经过操作、思考学生有三个答案:①从30里面拿出一个10,用10减6,再把剩下的数合起来;②4减6不够减缺2个,从30里减2个,剩下了28;③从30里拿出一个十和4合在一起,用14减6,再和20合在一起。“又提问:”到底哪种方法比较简便?“经过比较、讨论得出:个位不够减,从十位退1,在个位上加10再减比较简便。
Interest is the person's selective attitude towards objective things, and is a psychological tendency to actively recognize something or participate in certain activities. It is a great motivation for students to learn and develop their thinking. According to the characteristics of children being active, curious and unable to be sustained, I use different methods in classroom teaching to stimulate and maintain students' interest in learning so that their unconscious attention to teaching content can be converted into conscious attention and thus always Learn in a pleasant atmosphere, be edutainment. First, in the new lesson of exploration, stimulate interest in learning to create problems, generate doubt, stimulate interest. In the process of teaching, I adopted a different way of setting doubts, so as to set suspicion and suspicion, so that the classroom atmosphere ups and downs. Such as teaching abatement subtraction, I set suspicion. Show 34-6, the question: ”a bit on a few minus 6? “ Student answers: ”4-6 less enough? How to do? Students have questions, with questions to hands-on operation, seeking answers. After the operation, consider the students have three answers: ① from 30 inside out a 10, with 10 minus 6, and then the rest of the number together; 4 minus 6 less than enough to reduce 2, from 30 minus 2, leaving 28; ③ from 30 out of a ten and 4 together, with 14 minus 6, and then together with 20. “And ask: ” In the end what kind of method is more simple? “” After comparison, the discussion concluded that: a place less than minus, from the ten back to 1, plus 10 in the first place and then more simple.
