如何提高学生的解题能力,是数学教学研究的重要课题之一。通过今年的高考阅卷,发现不少学生解题时思路开阔,条理清晰,方法灵活;但也有相当一部分同学分析问题和解决问题的能力较差。造成这种差别固然有多方面的因素,但作为一个数学教师却不能不多从教学上去探究原因。 下面我们来看看今年高考数学(理工科)试题第七题考生解答的情况。对这道题,考生有不少好的解法,现就其中思路最为清晰的一两种评介如下:
How to improve students’ ability to solve problems is one of the important topics in mathematics teaching research. Through this year’s college entrance examination, it has been found that many students are open-minded, clear-cut, and flexible in solving problems; however, a considerable number of students have poor ability to analyze problems and solve problems. There are many factors that contribute to this difference, but as a mathematics teacher, I cannot go beyond teaching to explore the reasons. Now let’s take a look at the answer to the seventh question of this year’s college entrance examination mathematics (science and engineering) test. Candidates have many good solutions to this problem. The one or two comments that are the most clear of them are as follows:
