认知心理学认为:元认知就是关于认知的认知,即主体对自己或他人认知活动的自我意识和自我调控。在数学解题活动的不同阶段,元认知起着确定目标、制定计划,监控活动、调节过程、反思总结、发展能力的作用。随着元认知理论的发展,大量研究证实:学生的元认知水平通过培养和训练是可以提高的。教师在解题教学过程中可以有针对性地传授数学元认知知识,开发学生的元认知技巧,培养学生自我评 Cognitive psychology that: Metacognition is about cognitive cognition, that is, the subject’s own or other cognitive activity of self-awareness and self-regulation. Meta-cognition plays a role in determining goals, making plans, monitoring activities, regulating processes, reflecting on lessons learned and developing abilities in different stages of mathematical problem-solving activities. With the development of metacognition theory, a large number of studies confirm that students’ metacognition level can be improved through training and training. Teachers in problem solving teaching process can be targeted to teach mathematics metacognitive knowledge, develop students’ metacognitive skills, develop student self-evaluation
