Exploration and practice of inquisition teaching in Clinical Diagnostics based on Mayer's multimedia learning theory
Objective To explore the application of Mayer's multimedia learning theory in inqui-sition teaching in Clinical Diagnostics.Methods A virtual inquisition learning system based on Mayer's multimedia learning theory was constructed and applied in Diagnostics teaching practice.At the end of the course,an inquisition exam and a student satisfaction assessment were given to evaluate the application effects compared with those of traditional teaching method.114 clinical undergraduates of grade 2018 were selected and divided into the experimental group1(n=56)and the control group1(n=58)randomly.The experimental group1 implemented combined PBL and flipped classroom teach-ing method by using virtual inquisition teaching system.The control group1 adopted traditional teach-ing method by using conventional multimedia.118 clinical undergraduates of grade 2019 were also di-vided into the experimental group2(n=60)and the control group2(n=58)randomly.The experimental group2 implemented online live teaching by using virtual inquisition teaching system.The control group2 adopted pre-recorded teaching by using conventional multimedia.Results In the offline teach-ing experiment,the inquisition test score(85.36±8.45)of the experimental group1 was higher than that of the control group1(78.33±10.88)(t=3.843,P<0.001).The degrees of satisfaction to the course,enhancing interests in learning,intuitive learning experiences,learning initiatives,inquisition ability,communication and collaboration skills of the experimental group1 and the control group1 were 96.43%and 84.48%(χ2=4.464,P=0.031);93.86%and 79.31%(χ2=4.334,P=0.037);98.21%and 81.03%(χ2=8.928,P=0.003);96.43%and 77.59%(χ2=8.852,P=0.003);98.21%and 79.31%(χ2=10.078,P=0.002);92.86%and 75.86%(χ2=6.189,P=0.013),respectively.All data of the experimental group1 were higher than those of the control group1.But the degrees of guiding stu-dents'actively thinking and convenient for self-learning for the experimental group1 and the control group1 were revealed no statistical significance(P>0.05).In the online teaching experiment,the test score of the experimental group2 of grade 2019(83.75±5.43)was higher than that of the control group2(74.26±7.36)(t=7.949,P<0.001).The degrees of the satisfaction to the course,enhancing inter-ests in learning,intuitive learning experiences,learning initiatives,inquisition ability,communication and collaboration skills of experimental group2 and control group2 were 91.67%and 75.86%(χ2=5.453,P=0.020);93.33%and 72.41%(χ2=9.169,P=0.002);95.00%and 70.69%(χ2= 12.382,P<0.001);96.67%and 77.59%(χ2=9.676,P=0.002);100%and 70.69%(χ2=12.382,P=0.001);95.00%and 68.97%(χ2=13.664,P<0.001),respectively.All these data of the experi-mental group2 were higher than those of the control group2.But the degrees of guiding students'ac-tively thinking and convenient for self-learning for the experimental group2 and the control group2 were revealed no statistical significance(P>0.05).Conclusion In the situation of both online and offline teaching,the application of the virtual inquisition learning system based on Mayer's multimedia learn-ing theory can help students better grasp the methods and skills of inquisition.It has been improved the quality of inquisition teaching in Clinical Diagnostics.
