“以物体的一个特征作肯定与否定标准分类”的方法是:在提供的一组物体中寻找某一个特征,把它们分成两组。对其中一组作肯定性判断,对另一组按同一特征作否定性判断。一般用“是”与“不是”、“有”与“没有”、“在”与“不在”等表述,如“是苹果”“不是苹果”“有柄的苹果”“没有柄的苹果”等。这种分类方法对促进幼儿初步的逻辑思维能力,培养思维的变通性、灵活性是十分有益的。中班下学期幼儿尚处于前运算阶 The “standard classification of affirmative and negative objects as a feature” is to look for a certain feature in a given set of objects and divide them into two groups. Make a positive judgment on one of the groups and a negative judgment on the other group by the same characteristics. Commonly used are “yes” and “no”, “yes” and “no”, “yes” and “no” and other expressions such as “apples” “not apples” “apples with handles” “apples without handles” and so on . This classification method is very useful for promoting children’s initial logical thinking ability and cultivating the adaptability and flexibility of thinking.
