目前中学化学教学中,普遍反映学生解题能力差。例如今年高考化学试题,一般学生都说题目不难,应该成绩很高,但事实不然。学生解题能力差,原因有二:一是“双基”不过硬,二是解题不得法。这二者是相互联系、相互影响的,只有掌握了扎实的基础知识,解题时才能够思路清晰,左右逢源。同样,通过严谨的解题训练,基础知识才能融会贯通,得到巩固与深化。因此,在加强“双基”教学的过程中,一定要对学生进行严格的解题训练。我在指导学生解题时,主要抓了三个环节,即审题、剖题、解题。
At present, middle school chemistry teaching generally reflects poor students' ability to solve problems. For example, this year's college entrance exam chemistry questions, the average student is not difficult to say the subject, should be high, but the fact is not. Students problem solving ability is poor, for two reasons: First, “double-base” is not hard, and second, no solution to the problem. These two are interrelated and influence each other. Only by having a solid foundation of knowledge can we be able to clear our thinking and try our best both ways. Similarly, through rigorous problem-solving training, basic knowledge can be mastered, consolidated and deepened. Therefore, in strengthening the teaching of “double basis”, we must carry out rigorous problem solving training for students. When I guide students to solve problems, I mainly focus on three aspects, namely examining questions, examining questions and solving problems.
