Research On PBL Teaching Application Practice Supported By Micro Video

In the era of rapid development of the Internet,society has put forward higher requirements for people's information literacy,innovation ability,and comprehensive ability.Information technology courses are playing an increasingly important role in promoting students' all-round ability development.In the latest high school information technology curriculum standards(2017edition),four core literacy subjects are clearly put forward.However,the current information technology teaching is still based on "teaching".With less subjectivity,it is difficult for students to improve their core literacy of information technology,but the PBL model provides ideas for solving this problem.The PBL model creates real problem situations for students.Students solve problems and acquire knowledge and abilities in the process of independent study and group cooperation.This coincides with the practicality and operability of high school information technology courses,there by effectively improving students' use of information technology to solve practical problems.At the same time,in the context of the "micro" era,mobile learning and fragmented learning are gradually becoming the mainstream methods of informal learning,and micro-videos featuring short,precise,and micro-sized videos are widely used learning resources.The interesting performance of micro-video mobilizes students' interest in learning.It can be watched repeatedly and can meet the students' need for teachers to explain knowledge again.Therefore,applying micro-video teaching resources to high school information technology courses can not only effectively solve students' failure to keep up,single teaching method,low learning enthusiasm,and large gaps in student information literacy levels.Also test the effectiveness of micro-videos.Based on this,the author combines the PBL model,micro-video and high school information technology courses.Under the theoretical guidance of constructivism,situational teaching and intuitive teaching,combined with the investigation and analysis results of the current situation of micro-video teaching in high school information technology courses,Constructed the basic process of PBL teaching mode supported by micro-video for high school information technology courses.Subsequently,teaching experiments were carried out with the chapter of "Multimedia Information Processing and Expression" as an example.Data were collected through tools such as test papers,student satisfaction survey questionnaires,and group work display evaluation scales,and their teaching effects were analyzed.Studies have shown that the application of PBL mode supported by micro-videos in high school information technology teaching can indeed promote students' academic performance,autonomous learning,awareness of problem-solving skills,and interpersonal skills.
