The Project-based Teaching Practice Exploration Of The Module Of High School Information Technology "Algorithm And Program Realization"

With the rapid development of information technology and the wide application of artificial intelligence and Internet of Things,programming literacy and programming education have received more and more attention from society.Algorithm and program implementation are the core content of programming education.The teaching of this part of the module content is presented by the Ministry of Education issued the"Standards for Information Technology Courses in General High Schools" in 2017 with clear requirements.The new curriculum standards also propose to infiltrate project-based teaching in teaching methods and teaching modes and set the teaching content as a project to start teaching.This research is based on the guidance of the new curriculum standards and is the teaching practice of the content of the high-level information technology "algorithm and program realization" module.The paper firstly combs the relevant literature on project-oriented teaching and analyzes the theoretical basis of project-based teaching and the characteristics of project-based teaching.Then,the project-oriented instructional design mode suitable for the teaching content of this research was selected and the five "Algorithms and Programs Realization" teaching projects which are close to the students’ learning life were formulated according to the students’ learning characteristics they are "burning calories" and "wonderful Spiral,Traffic Lights,Simple Order System,and Lucky Numbers.The knowledge points of the five projects are progressively advanced on the level of difficulty and the necessary algorithmic knowledge for high school is developed in a project-based way.Teaching practice.In order to verify the influence of project-based teaching on algorithm learning,a multi-teaching evaluation system was developed.Students were comprehensively evaluated through several methods and dimensions such as self－evaluation,group mutual evaluation and classroom knowledge test,and compared and analyzed by independent sample T test.The analysis shows that the project-based teaching carried out does have some help for students to learn algorithm knowledge.The paper also summarizes several factors that should be considered in the development of project-based teaching through interviews with students and teachers and combined with reflection on teaching.Through the practice and exploration of this research,I hope to provide some reference and reference cases for enriching the teaching of the algorithm and program realization of high school information technology.
