在小学数学平时练习或考试命题中,概念题通常都占有一定的比重,并常以填空、判断、选择等形式出现;可是,在解答概念题时,小学生由于抽象思维能力、空间想象能力以及对于概念的分析、判断、推理能力较差,特别是对于一些似是而非、容易混淆的概念往往把握下准、理解不透,因而常常发生错误。针对这种情况,本人在教学过程中,除了力求向学生讲清概念外,还注重了对概念题解题方法的指导,对学生授之以法,导之以路,使其能够举一反三,少走弯路,合理、正确地通过多种途径解答题目。现不全面地谈谈解答概念题几种常用的方法,以期得到同行们的指教。
In elementary school mathematics practice or examination propositions, conceptual questions usually occupy a certain proportion, and often appear in the form of filling in blanks, judgments, and choices; however, in solving the concept questions, pupils have abstract thinking ability, spatial imagination ability, and The analysis, judgment, and reasoning ability of the concept are poor. In particular, the concepts that are plausible and confusing are often undermined and incomprehensible. Therefore, errors often occur. In view of this situation, in my teaching process, in addition to striving to clarify the concept to the students, I also paid attention to the instruction of the problem-solving methods for the concepts, and taught the students methods to guide them. Take detours and answer questions in a variety of ways in a rational and correct manner. We do not comprehensively discuss several commonly used methods for solving conceptual problems in order to gain the advice of our colleagues.
