The application of self-designing experiment in the experimental teaching of biochemistry / 中华医学教育探索杂志

ABSTRACT

Objective To investigate the effect of the teaching method of self design experiment in biochemistry experiment teaching.Methods A total 196 students of Grade 2013 majored in clinical medicine from the Medical College of Shanxi Datong University,were randomly divided into two groups.Students in the control group used traditional teaching method,while students in experimental group were taught with designed experiment teaching method,choosing the experimental project independently,designing and operating the experimental,then summarizing the experiment.After the end of the experiment,the experimental results of each group were evaluated,and the questionnaires were distributed to two groups of students.The teaching effect and the influence on the students were investigated.SPSS 13.0 was used for data processing and the data was made test and t test.Results The experimental grade analysis showed that experimental group was obviously higher than control group in the total score[(83.50 ± 3.27) vs.(65.62 ± 4.20)] and grade of test report[(25.27 ± 1.55) vs.(19.21 ± 2.01)],there was statistically significant (t=33.24,P=0.034;t=23.59,P=0.025),experimental group had significant(t=13.71,P=0.000) higher scores than control group in experimental test scores [(23.41 ± 2.27) vs.(19.42±1.78)],but there was no statistically significant difference (t=23.12,P=0.136) in usually scores[(34.29 ± 2.17) vs.(26.91 ± 2.30)].Survey results showed that the design experiment teaching had very obvious advantages than the traditional teaching method in students' self-study ability (P=0.000),the ability to solve problems (P=0.000) and team spirit of cooperation (P=0.000) culture.Conclusion Compared with traditional teaching method,the self-designed experimental teaching method was better in stimulating students' study interest and analyzing and solving the problem,laying a good foundation for clinical practice of Medical College Students.
