多年来,我校数学教研组在“知识同化理论”的指导下,许多教师作了有关研究,取得了一定的研究成果。我们认为知识同化有两个重要过程:其一,知识同化是新学习的观念(知识)与认知结构中原有观念相互联系、相互作用的过程。其二,知识同化是把新学习的内容纳入原有数学认知结构,并使原认知结构得到补充、改造或完善的过程。上述两个过程是在教师的指导下,学生主动地、积极地用原有认知结构去同化新知才能完成的。我们在研究过程中发现,有的学生能顺利地完成上述过程,而有的学生则不能顺利地完成上述过程,除了我们已研究的如教学内容的组织,教师的教学方法,学生原有的认知结构等等原因外,一个重要原因是这些能顺利同化新知的学生,在学习过程中,能采用一些有效的学习方法和学习策略,从而促进了知识同化的进行。因此,这几年我们又在原有研究基础上,对指导学生掌握一些学习策略,从而提高学习效率进行了初步探索。在学习过程中,用以提高学习效率的任何学习活 Over the years, under the guidance of “Theories of Knowledge Assimilation”, many teachers of Mathematics Teaching and Research Group of our school have made relevant researches and obtained certain research results. We believe that there are two important processes of assimilation of knowledge: First, assimilation of knowledge is the process by which the concepts (knowledge) of new learning and the original concepts in cognitive structure are interrelated and interacting. Second, knowledge assimilation is the process of incorporating the content of new learning into the original cognitive structure of mathematics and supplementing, reforming or improving the original cognitive structure. The above two processes are accomplished by teachers under the guidance of teachers who actively and actively use the original cognitive structure to assimilate new knowledge. During the course of our research, we found that some students successfully completed the above process, while others failed to complete the above process successfully. Apart from the organization we have studied such as teaching contents, teachers 'teaching methods, students' original recognition One of the important reasons for this is that these students, who can successfully assimilate new knowledge, can use some effective learning methods and learning strategies in the learning process to promote knowledge assimilation. Therefore, in the past few years, on the basis of the original research, we conducted a preliminary exploration on how to guide students to master some learning strategies and thereby improve their learning efficiency.
