| The curriculum standard for senior high schools（2017 Edition）updates the teaching content,attaches importance to the concept of discipline as the core,and the curriculum content is structured.Therefore,how to change the single class teaching and optimize the curriculum structure is not only the key to the curriculum reform,but also the problem that front-line teachers face and need to be solved urgently.Unit teaching is a hot spot in educational research in recent years.It helps to integrate knowledge,form a complete knowledge structure,and examine whether the teaching objectives are achieved from a higher level.Therefore,it is the current research trend to expand single class teaching into units.In the field of cognitive psychology,ACT-R theory is a relatively mature theory taking the road of mathematics at home and abroad.This thesis optimizes and deeply analyzes the unit teaching through ACT-R theory,constructs a high school mathematics unit teaching model based on ACT-R theory,and widely applies cognitive psychology to the field of pedagogy to improve teaching efficiency,which has certain research significance.By reading a large number of documents and systematically analyzing ACT-R theory and unit teaching,the author finds that ACT-R theory has the dual advantages of unit integration and improving teaching process in mathematics teaching research.Therefore,this thesis mainly aims at the unit teaching design,under the guidance of ACT-R theory,combined with Bloom’s classification of educational objectives and modern educational technology,optimizes the common unit teaching mode Addie mode,constructs the unit teaching model under ACT-R theory and designs the corresponding unit teaching scheme.In order to verify the effectiveness and credibility of the model,the design refers to the teaching case of power function unit,carries out experimental research,sets up the experimental class and the control class,and verifies the effectiveness of the model by analyzing the test results,paper and pen test results and interview results of the two groups of students,Finally,the experimental conclusion is drawn: the high school mathematics unit teaching model based on ACT-R theory is indeed conducive to students’ better transfer and systematic understanding of knowledge,achieve exquisite practice,stimulate students’ learning enthusiasm to a certain extent,and is suitable for high school mathematics unit teaching.The research shows that the unit teaching model designed under the guidance of ACT-R theory is meaningful.This research can help students simplify complex problems,improve students’ non cognitive factors and solve problems flexibly.However,the model only guides one or two units,which should be improved in the process of teaching practice. |
