借助解题错例的分析能够很好展现出学生的认知偏差以及教学中的难点,这些都能够很好地给教师以指引。本文将结合实例谈谈从解题错例分析高中数学难点及认知偏差。一、漏解问题的发生漏解问题的发生大概是所有的解题错例中最常见的一种,解题过程中遗漏某个解的状况也非常普遍。漏解的问题几乎所有学生都会发生,对于这个问题展开剖析后我们发现,漏解通常是由于学生的大意马虎,可能对于某个地方过于疏忽造成解题的遗漏。然而,如果对于这种现象进一步探究不难发现,漏解某种程度是由于学生的基础知识掌握
The analysis of problem-solving mistakes can well demonstrate students’ cognitive biases and difficulties in teaching, which can give teachers good guidance. In this paper, we will discuss the difficulty of mathematics in high school and the cognitive bias from the analysis of the wrong example. First, the problem of misinterpretation of the problem of misunderstanding The problem of misunderstanding is probably the most common one among all the problem-solving mistakes. It is also very common to leave a certain solution out of the problem-solving process. The problem of misunderstanding happens to almost all students. After analyzing this problem, we find that the misunderstanding is usually due to the carelessness of the students and may be too negligence to solve the problem. However, if it is not difficult to find further exploration of this phenomenon, it is due to the basic knowledge of the students.
