Research On The Application Of PBL Teaching Method In High School C++ Programming Course

In the new curriculum standard "information technology curriculum standard for senior high school",it is proposed that the core literacy of information technology includes four core parts:Information Awareness,Computational Thinking,Digital Learning and Innovation,and Information Society Awareness.Among them,Computational Thinking refers to a series of thinking activities produced by individuals in the process of forming problem solutions by using the thinking methods in the field of computer science.Computational Thinking is an essential internal thinking quality of teenagers in the 21st century,and programming course provides a platform and opportunity for cultivating students' Computational Thinking.Program design is the process of solving specific problems.It is a language level problem solving process.Compared with the abstract level and system level problem solving process,it is easier to understand and learn.Therefore,in the process of programming,we can cultivate students' consciousness and ability to solve problems with "the same thinking as computer scientists".PBL teaching method sets learning into meaningful problems and situations,so that students can learn the scientific knowledge hidden behind the "problem" by analyzing real problems,form problem-solving skills,and cultivate the ability of autonomous learning.Take the problem as the starting point to stimulate students' initiative and interest in learning.The steps of PBL teaching method mainly include:putting forward problems,creating situations,analyzing problems,exploring solutions,group cooperation,problem solving,achievement display and feedback evaluation.The core of this teaching method lies in the selection and design of problems and situations.Based on Constructivism theory,Cooperative Learning theory,Theory of multiple intelligences and Discovery Learning theory,this paper studies the application and effect of PBL teaching method in high school C++programming course.The research object is a senior high school freshman in Zhengzhou.They generally have a preliminary understanding of programming,have a certain foundation and have a strong individual interest.This research adopts the methods of comparative research,questionnaire survey and literature research to carry out teaching practice and research in the quasi experimental research environment.The research issues include the research on the current situation of high school programming curriculum,the teaching design and Application Research of task driven PBL teaching method.The research shows that compared with the traditional teaching methods,the application of PBL teaching method in high school C++programming course can promote the improvement of students' learning interest and programming ability,that is,using PBL teaching method in programming teaching has a positive impact on students'learning.It is hoped that this study can accumulate PBL teaching experience for middle school information technology course teaching,and provide reference for schools to carry out programming course.
