反思,就是能够以自己及其行为为对象来进行审视和思考.反思,是一种可贵的思维方式.只有学会反思,一个人才能不断地矫正错误,不断地探索和走向新的境界.孔子曰:“每日三省吾身……”“学而不思则罔……”.学而不思则罔,意思就是学习只知死记硬背而不加以思考、消化的话,这样的学习是毫无收获的.美国学者波斯纳认为:“没有内在反思的经验是狭隘的经验,至多只能成为肤浅的知识.如果教师仅满足于获得的经验而不对经验进行深入的思考,那么他的教学水平的发展将大受限制,甚至有所滑坡.”他阐明了教师成长过程应该是一个总结经验、捕捉问题、反思研讨、把感性认识上升为理性思维的过程.《科学》课程学科综合性强,内容涉及面广,概念多.概念及公式、定律是思维的基本单位,要促进学生思维的发展,必须首先强化概念教学.如何让学生牢固掌握概念的本质属性,激发其解决问题的积极性,增强灵活性呢?这就要求教师在教学中积极地从“教学目标的设置”“课程资源的整合”“教学策略和方法的选择”及“教学评价”等维度,开展反思,积极地引领学生自主的获得概念,实现概念体系的构建.
Reflection is the ability to look at and think about ourselves and their actions.Reflection is a precious way of thinking.Only by learning to reflect on it, one can continually correct mistakes and continue to explore and move toward new realms. : “Three provinces every day of my body ...... ” “learn without thinking is indiscriminately ...... ”. Learning without thinking is indiscriminate, meaning is learning only know rote rather than thinking, digesting words, so Learning is fruitless.American scholar Posner that: “experience without internal reflection is a narrow experience, at best, can only become superficial knowledge.If the teacher is satisfied with the experience gained without in-depth thinking of the experience, then His level of teaching will be greatly restricted, or even decline. ”He clarified that the process of teacher growth should be a process of summarizing experiences, capturing problems, reflecting on discussions and raising perceptual knowledge to rational thinking.“ Science ” The subject is comprehensive and comprehensive, covering a wide range of concepts and concepts.Concepts and formulas, laws are the basic units of thinking, to promote the development of student thinking, we must first strengthen the concept of teaching.How to make students firmly grasp the concept of The nature of the property, to stimulate their enthusiasm to solve the problem, to enhance the flexibility? This requires teachers in teaching actively from the “teaching objectives set” “curriculum resources integration ” “teaching strategies and methods of choice ”And“ teaching evaluation ”and other dimensions, carry out reflection, and actively lead the students to obtain the concept of autonomy, to achieve the conceptual system.
