| Since the nineties of the 20 th century,countries all over the world are vigorously carrying out basic education reform to cultivate new talents to meet the development needs of the new era,and the core literacy development system of Chinese students has emerged.Based on the discussion of the theory of understanding learning,reverse design and unit teaching,this paper focuses on the process of unit teaching design and the effect of teaching practice under the guidance of the theory of understanding learning,in order to make its own contribution to the transformation of traditional scientific teaching concepts and methods and the improvement of students’ core literacy.This paper includes the following six parts:The first part is the introduction of this paper,mainly introduces the reason for the topic,research purposes,research significance.It is the demand of the times to promote the cultivation of Chinese students’ core literacy through education reform.The key of education reform is curriculum reform,and the key of curriculum reform is classroom reform.This paper aims to explore the classroom teaching strategies based on the understanding unit design,so as to provide strategic reference for the current front-line classroom teaching.The second part is a review of related research,mainly on the current situation of understanding learning and unit design at home and abroad.Summarize the existing research results,determine the research direction,and prepare for further research.The third part is the theoretical basis of this paper,mainly discusses the understanding of learning theory,reverse design,unit teaching theory,and defines the relationship between the three,that is,with the help of reverse design theory,to arrange unit learning,in order to achieve the purpose of understanding learning.The fourth part is the focus of this paper,which mainly explores the design process of unit teaching under the guidance of understanding learning theory,including the establishment of teaching units,the construction of large concepts,the setting of expected unit learning objectives,the determination of evaluation methods,the design of corresponding learning activities,and the implementation of teaching process.The fifth part uses the method of questionnaire survey to investigate the teaching practice effect of unit teaching design under the guidance of understanding learning theory,and uses SPSS statistical software to analyze the results of questionnaire survey.The sixth part summarizes the research conclusions,mainly including the following three aspects: first,the unit teaching design based on understanding and its teaching practice are effective for improving students’ understanding level.Secondly,it also brings great changes to science class.Third,the change of students makes teachers’ teaching concept change.At the end of the paper,the shortcomings of the research and the future research are also prospected. |
