| Jigsaw teaching method based on PBL is a new teaching method that combines problem-based teaching method with Jigsaw teaching method.This teaching method integrates the advantages of various teaching programs,combines the problem-oriented learning mode with the student-centered cooperative learning mode,and effectively solves the problems of low classroom efficiency and low learning enthusiasm.It is very suitable for the teaching system of secondary vocational schools.Through literature research,this study sorted out the basic concepts,research status and related theoretical knowledge of PBL and Jigsaw teaching methods,which laid a sufficient theoretical foundation for the subsequent study of the combination of the two teaching methods.The object of this study is the students of computer major in secondary vocational schools.Using the method of questionnaire survey to investigate the students’ course learning status.According to the results of the questionnaire survey,the problems existing in the current teaching are analyzed,and then combined with the teaching characteristics of the computer course in secondary vocational school,the formulation of solutions,the design of PBL teaching scheme based on the spelling mode.Taking Linux operating system course as an example,quasi-experimental research method is used to carry out experimental research.Two parallel classes in the first grade of computer network major in a secondary vocational school were taken as experimental objects.The experimental class adopted the spelling method based on PBL,and the control class adopted the traditional teaching method of "exploration + practice".Finally,the average score of the middle and late period is used to verify the teaching effect,which proves that the PBL based spelling schema teaching method can effectively improve the scores of computer majors in secondary vocational schools.The main conclusions of this study are as follows: First,the classroom teaching effect of computer major in secondary vocational schools is poor,students lack enthusiasm,and teachers are difficult to promote the teaching progress.Second,secondary vocational school computer course entry threshold is high,the learning process is difficult to combine with practical problems.Thirdly,PBL based jigsaw teaching method can effectively solve a series of teaching problems,clarify teaching objectives,improve students’ learning enthusiasm,make students study hard through cooperative learning and benign competition,create a good learning atmosphere,and improve the classroom learning effect. |
