PBL Design And Application Research For The Core Literacy Of High School Information Technology Disciplines

This study aims at the phenomenon that high school information technology courses are positioned as "tool courses"at present,and combined with the purpose of discipline core literacy in "high school information technology curriculum standards"(2017 edition),it is found that the current teaching and learning mode of high school information technology courses is badly in need of transformation.This study attempts to change this situation by adopting a problem-based learning model and tries effectively to cultivate the core literacy of information technology subjects in senior high school.Through literature review,it is found that the learning effect of the existing PBL mode cannot meet the requirement of cultivating students’discipline core literacy,which is mainly reflected in:(1)the design and evaluation of existing PBL mode activity pay more attention to the result of learners’ problem solving,but they neglect the process of problem solving;(2)the design of existing PBL mode activities is monotonous,which is difficult to reflect the characteristics of the discipline.Therefore,it cannot obviously promote the cultivation of discipline core literacy.To solve the above problems,this study will focus on the activity framework construction and specific learning activity design of PBL mode.First,the five core elements of PBL activity structure,namely problems,roles,tools,connections and results,are sorted out.At the same time,it summarizes the four key characteristics of PBL mode,that is to say,"problem" as the clue,"real situation" as the condition,"students" as the subject and "problem solving" as the result.Then,based on the curriculum standards of information technology in senior high school(2017 edition),this paper analyzes and explains the main ideas of the core literacy of information technology in senior high school:to enhance the understanding of knowledge in the known world,to guide the knowledge transfer in the real world,and to promote the knowledge innovation in the unknown world.By sorting out the PBL model and combining the characteristics of information technology courses in senior high school,six elements of PBL activity process are summarized,namely,exploration,reasoning,conception,making,evaluation and modeling.Based on this,this study attempts to construct a PBL activity framework for senior high school information technology discipline core literacy,and designs the specific learning activities.According to the framework of the activity,with the help of the two units of "text processing and processing" and "table processing and processing" in the information technology course of senior high school,three questions of "celebrating the festival series tabloid","does the constellation match the character" and "where is the pocket money"were designed to carry out the case implementation.Each round of case implementation will carry out procedural and summative evaluations evaluation to find out the shortcomings of learning activity strategies and make corresponding strategy adjustments.The students in the experimental class have achieved certain results through teaching and learning in PBL mode during this period.In terms of information awareness,students can quickly grasp the key points of the problem.In terms of computational thinking,the thinking mode of most students has been improved.In the process of problem solving,the thinking of modeling is reflected,and the thinking is divergent and organized.In the aspect of digital learning and innovation,students have realized that data resources are used to facilitate learning,and digital tools are used to create better works.However,digital tools is rarely used in practice.In the aspect of information social responsibility,students’ awareness of information social responsibility is gradually increasing.Of course,the level of core literacy of high school students’ information technology discipline needs to be further improved.
