“余味”就词本身来说,含义是“留下的耐人回想的味道”。引申到小学数学课堂教学中,笔者认为是指教师在课堂上要给学生吃到“橄榄”,使他们在课后留下非常耐人回想的“味道”。具体是指教师在课堂教学中要认真地实施“总结、融会、类推、实践、创见、引路”等十二字。其实质是“以学生为主体,教师为主导”的教学思想的具体体现。 1、总结。对于课堂教学内容的重点、关键和有关结论性的东西,要让学生通过观察、思考、讨论后自己总结出。教师的职责是提供材料和创设情境,必要时给予点拨。例如,教学小数的性质时,师生共同列举一些商品价格、物体的长度等生活实例,以及引导学生看课本的插图后,教师就可以启发说:“请同学们观察这些情况有什么规律?”让学生通过观察、思考后得出小数的性质。此外,在新授 “Afterglow” means the word itself, the meaning is “left behind the taste of people think back.” Extended to the primary school mathematics classroom teaching, I believe that teachers in the classroom to give students to eat “olive” so that they left a very patient after school recalled the “taste.” Specifically refers to the teacher in the classroom teaching should conscientiously implement the “summary, integration, analogy, practice, creativity, lead the way” and other words. Its essence is the concrete manifestation of the teaching idea of ​​“taking students as the main body and teachers as the mainstay”. 1, concluded. For the focus of the classroom teaching content, the key and the conclusions of the relevant things, let the students through observation, thinking, discussion summed up. The teacher's job is to provide materials and create situations, and to give advice if necessary. For example, in the nature of teaching decimals, teachers and students jointly enumerating some examples of life such as the price of goods and the length of objects, and guiding students to read illustrations of the textbooks, the teacher can inspire him and said: “Ask the students to observe what is going on in these situations?” Allow students to observe, think after the decimal fraction of the nature.
