Research On The Teaching Design Of High School Information Technology And The Construction Of Question Answering System Based On PBL

At the beginning of 2018,the Ministry of Education officially promulgated the Standards for Information Technology Curriculum for General High Schools(2017 Edition)(hereinafter referred to as the "new curriculum standard").The new curriculum standard states that the high school information technology curriculum aims to comprehensively improve students 'information literacy,focusing on developing students' core academic literacy,including improving students 'digital learning and innovation capabilities,and enhancing students' active participation in the information society.Affected by traditional teaching,current information technology teaching still has the problem of students' lack of subject status and lack of creativity,and problembased learning(PBL)provides ideas for changing this situation.PBL is a problemcentered,teaching environment based on problem-solving,which enables students to acquire new knowledge through independent inquiry and collaborative learning.The application of the PBL teaching mode in high school information technology classroom teaching helps to cultivate students' ability to find and analyze problems,and enables students to realize the social construction of knowledge,the practical training of skills and the creative development of thinking in the process of problem solving.This article takes the new curriculum standard as a guide to carry out research on the PBL teaching design of high school information technology.At the same time,it closely focuses on the nature and characteristics of PBL teaching,and designs and develops a question-and-answer system to assist in the implementation of PBL teaching.Help students solve problems.The main work of this paper includes the following aspects:(1)combing the research status and results of PBL teaching,high school information technology course teaching and question answering system based on existing literature research,summarizing the characteristics of PBL teaching mode and classic teaching process;(2)Starting from the support of technology for learning,the characteristics and functions of the question answering system supporting PBL teaching were analyzed,and the theoretical basis for the design of the question answering system was determined;(3)According to the characteristics of the senior high school information technology curriculum and its internal connection with PBL teaching,respectively From the aspects of teaching goals,teaching problems,teaching process,and teaching evaluation,the detailed design and description of each application link of PBL in high school information technology teaching are emphasized,and the principles of problem design and problem classification in high school information technology PBL teaching are emphasized.And problem design strategies;(4)Based on the high school information technology PBL teaching activity process and the current status of existing PBL teaching problems designed in this paper,design and develop a question answering system that supports high school information technology PBL classroom teaching,specifically related to the functional design of the question answering system,Construction ideas and strategies for the problem base;(5)This paper combines the PBL teaching design viewpoint with the high school information technology teaching content,designs specific teaching cases and implementation process,and conducts statistics and analysis on experimental data to verify the application effect of PBL teaching in high school information technology curriculum and the feasibility and effectiveness of the question answering system.
