弱智儿童元认知知识的发展特点

The Development of the Metacognition Knowledge of Mental-retarded Children

采用拼图任务考查弱智儿童元认知知识的发展特点,结果表明,弱智儿童主体性元认知知识随着年龄增长不断发展,但直到高年级,儿童的主体性元认知知识水平仍较低;任务难度的元认知知识随年龄增长发展缓慢;弱智儿童具有一定的策略知识,且随着年龄增长,内部策略的使用频率增多,外部策略的使用频率减少。

Task of matching puzzle was used to explore the development of the metacognition knowledge of mental-retarded children.Results showed that children＇s metacognition knowledge,including knowledge about person,task and strategy,increased with age.But still to the age of higher grade,the development level of mental-retarded children＇s metacogntion knowledge is rather low.There were significant changes in the use of inner strategy from lower grade to higher grade children.
