联想是由一事物想到与其有关的另一事物的心理过程。联想,可以把有共同点的事物联系起来。启发学生联想,可以点燃智慧的火花,培养思维的创造性。例如,在复习扇形面积时,我让学生解答这样一道题:求右图扇形的面积(单位:厘米)。如果运用扇形面积公式(S=(πr)~2/360_n)解答此题,必须先求出圆心角的度数。这样,就给解题带来了很大的麻烦。于是,我启发学生联想:扇形与三角形相
Associations are mental processes in which one thing comes to mind with another. Lenovo, can have something in common with the connection. Inspire student associations, you can ignite the spark of wisdom, training creative thinking. For example, in reviewing the area of a fan, I asked the students to answer the following question: Find the area of the right fan (in centimeters). If you use the fan area formula (S = (πr) ~ 2 / 360_n) to solve this problem, you must first find the angle of the central angle. In this way, to solve the problem has brought a lot of trouble. So, I inspired student associations: fan-shaped and triangular phase
