Research On The Application Of Problem-Based Learning In Computer Courses

The report to the 19 th national congress of the communist party of China(CPC)called for "carrying out large-scale vocational skills training,focusing on solving structural employment problems,and encouraging entrepreneurship to promote employment".This has pointed out the direction for the development of vocational education and planned the prospect.In 2019,the implementation plan for the reform of vocational education issued by the state council put forward a roadmap,timetable and mission statement for deepening the reform of vocational education,and identified the priorities for the next five years,which attracted wide attention from all sectors of society.In recent years,vocational education ushered in the "golden age".From the modern vocational education system construction plan(2014-2020)",to "improve the vocational education and training system,deepen teaching fusion,university-enterprise cooperation" to the party's 19 report,vocational colleges in our country was introduced to shenzhen the first world-class construction plan,vigorously developing vocational education become the common consensus and action,to promote the reform of related to lay a solid foundation under the new situation.Secondary vocational education is an indispensable part in the field of vocational education in China.It is the general trend to develop secondary vocational education,improve teaching quality and improve teaching effect.PBL teaching method is a kind of teaching method based on questions.Its main features include: problem guided learning,student-centered and group discussion.The teaching method was first applied in the clinical field of medicine,and then gradually applied to other subjects after achieving remarkable teaching results.The introduction of PBL teaching method in our country the time of late,it was not until the 1990 s began to develop,but so far,the teaching method is applied to the research in the field of computer professional course is relatively small,this paper tentatively the PBL teaching method is introduced into the school computer field(in the secondary vocational computer software tool use,for example),tries to solve the secondary vocational computer of poor classroom discipline in the class,students' classroom participation is low,the problem such as poor teaching effect,for the reform in teaching of secondary vocational schools to provide some reference,At the same time,it also provides corresponding support for the further research of this teaching method in the field of computer.The research object selected in this paper is the second grade students majoring in computer science of jinan media school.The research methods mainly include literature method,investigation method and classroom observation method.Experimental class and control class were set up to compare and analyze the changes in study habits,classroom participation,learning ability and learning effect of students in the two classes through pre-test and post-test,so as to verify the advantages of PBL teaching method in this course.Through a comprehensive analysis of the performance of secondary vocational students in class and the characteristics of PBL teaching method,a complete set of student-centered teaching process is designed to give full play to students' subjective initiative,and a complete teaching activity process is given for a certain chapter.After the experiment through the SPSS analysis in class two grade data,found that there was no significant difference between two classes after learning over a period of time,began to appear more significant differences,including the experimental classes in grades than that in comparative classes after PBL teaching method has obvious improvement,experimental classes in such aspects as pass rate,the excellence rate is better than that in comparative classes;Through questionnaire analysis,it was found that students in the experimental class could accept PBL teaching method and teaching activities.On the whole,this tentative introduction of PBL teaching method into the field of professional computer courses in secondary vocational schools has achieved good results in terms of teaching effect and student acceptance.
