思维性课堂,是指以学生和教师的思维活动为中心活动的课堂教学。构建思维性课堂,必须引导学生充分调动自己的思维中枢,主动探究和学习,以提高课堂教学效率。一、认知冲突,诱启思维发展之门教学中,教师如能巧妙设计,引导学生发现新旧认知存在冲突,能够很好地调动学生探究的兴趣,为学生的自主学习找到充足的动力,并开启学生有效思维之门扉。例如,在教学“小数除法(二)”时,学生通过前面几节课的学习已经具备了除数是整数的除法和除数是小数的小数除法的思维方法,于是教师出示了苏教版五上数学第98页例题7,并提出问题“海狮的最高速度是多少千米每分?”学生很快列出了算式:40÷60,然后毫无迟疑地开始了自己的计算。但是,不到一分钟时间后,所有学生都很为难地抬起了头,“老
Thinking of the classroom, refers to the activities of students and teachers thinking activities as the center of classroom teaching. To construct a thinking class, we must guide students to fully mobilize their own thinking center, take the initiative to explore and learn in order to improve classroom teaching efficiency. First, the cognitive conflict, induce the development of the door of thinking Teaching, if teachers can skillfully design and guide students to find new and old cognitive conflicts, can well arouse the interest of students to explore for students to find adequate motivation to learn, And open the door to effective thinking of students. For example, in the teaching of ”fractional division (b)“, the students already had the thinking method of dividing the divisor by an integer and by the fractional divisor by the fractional divisor, On math page 98, example 7, and ask questions, ”What is the maximum speed of a sea lion?“ Students quickly set out the formula: 40 ÷ 60 and started their calculations without any hesitation. However, less than a minute later, all students looked up very hard, ”old
