Research On Concept Formation Strategies In Junior Middle School Information Technology Python Teaching

With the promulgation of the Standards for Information Technology Curriculum for General Senior High Schools(2017 Edition),"Computational Thinking" has received unprecedented attention as one of the core literacy of the four high school information technology subjects,and its concepts and connotations have quickly spread to junior high schools In addition,the teaching of information technology in junior high schools also pays more attention to the cultivation of students' computational thinking.As an object-oriented dynamic class language,Python has quickly become a good software for junior high school learning algorithms and programming with its advantages such as simplicity,easy learning,and high portability.For example,Shandong Education Press' s 2018 junior high school information technology textbook has compiled Python as the preferred software for teaching in the fourth volume of textbooks.This study also framed the research scope in the teaching of junior high school Python software to meet the new curriculum standard.The trend of reform is in line with the choice of the times.The study of concepts is the first and most important step in the learning of many knowledge.The same is true of the study of related concepts in Python.It runs through the understanding of the content and content of the entire algorithm and programming.From the macro concept to the concrete concept,it is infiltrated that the content of the program design is different from other parts,and the Python software is different from other software.It also exudes the mentality and connotation of computational thinking and algorithmic thinking.Therefore,research on the concept formation strategy in Python teaching is helpful for students to learn Python directly,and it also greatly enhances the training of students' computational thinking and algorithmic thinking.This thesis is divided into six chapters,and the main body is composed of chapters two to six.The content of each chapter is summarized as follows:The first chapter is the introduction.In addition to explaining the background and origin of the research,the content and methods of the research,the value and ideas of the research,it also includes a review of related literature.The second chapter defines the related concepts and determines the theoretical basis.This chapter defines important concepts such as "concepts in Python","concept formation",and "concept formation strategy",and finds relevant theoretical foundations that can support this research from three aspects: framework support,tool support,and connotation support.The third chapter is the supportive analysis of conceptual positioning and related theories on strategy formulation.This chapter mainly analyzes the theoretical basis of this research,and specifically analyzes the content of the second unit of the fourth unit of the "Technology Programming in Python" in the fourth edition of the information technology textbook of the junior high school of Shandong Education Press in 2018.The positioning was carried out,and the framework support and tool support for strategy formulation were analyzed in detail.The fourth chapter is the comprehensive formulation of concept formationstrategies in junior high school information technology Python teaching.This chapter is based on the determination of specific concept research objects,and finds the relevant basis that can support the concept formation strategy formulation,and comprehensively develops the targeted concept formation strategy with the support of these foundations.The fifth chapter is the experimental verification of concept formation strategies in junior high school information technology Python teaching.This chapter mainly presents the implementation process of concept formation strategies in the form of cases,and analyzes the specific performance of strategies in the process of teacher-related teaching of students in the process of teacher Python teaching through educational experiments.Make a comprehensive judgment statement of value.The sixth chapter is the summary,limitations and prospects of this research.This chapter,as the last chapter,summarizes the main contributions of this research,discusses the practical guiding significance of the research on the teaching of related concepts in Python,also reflects on the research process,discusses the limitations of the research,and points out the future of research.
