电子作业在提升人体寄生虫学实验课教学效果中的作用

目的 探讨手机拍照提交电子作业的形式是否能提升临床医学专业本科生人体寄生虫学实验课的教学效果。 方法 将安徽医科大学 2015 级国际班临床医学专业学生分为 3 组,在人体寄生虫学实验课程中分别提交纸质作业、电子作业以及纸质和电子作业。 以观测 25 个寄生虫标本为期末考试,分析三组学生的成绩。 结果提交纸质作业组、提交电子作业组以及提交纸质和电子作业组 3 组学生的成绩分别为(83. 07±5. 09)分、(82. 55±4. 52)分和(85. 66±4. 48)分,组间差异有统计学意义( F= 3. 83,P<0. 05)。 三组学生的显微镜下观测成绩分别为(58. 33±5. 91)分、(57. 69±5. 27)分和(60. 69±5. 09)分,组间差异有统计学意义( F= 2. 62,P<0. 05);三组学生的原虫样本观测成绩分别为(33. 25±2. 98)分、(33. 60±2. 85)分和(35. 29±2. 17)分,组间差异有统计学意义( F= 5. 06,P<0. 05)。 结论 在人体寄生虫学实验课中同时提交纸质和电子作业可以提高学生实验课成绩,尤其是需要显微镜下观测的标本的答题准确率。

Role of electronic homework in improving the teaching effect of experimental course of Human Parasitology

Objective To investigate the role of electronic homework in improving the teaching effect of experimental course of Human Parasitology. Methods The undergraduates majoring in clinical medicine from international class,enrolled in Anhui Medical University in 2015,were included,and divided into three groups. Homework on the experimental course of Human Parasitology was delivered by either hard copy(H group) or soft copy(E group),and hard copy plus online submission(H+E group). Academic achievement upon completion of the course was evaluated by identifying and describing the 25 parasite specimens in the final examination paper. Results The final scores of students were in H group,E group and H+E group were (85. 66±4. 48) points,(83. 07±5. 09) points and (82. 55±4. 52) points,respectively. The difference was significant ( F= 3. 83,P< 0. 05) . The results of microscopic identification of parasite samples were ( 58. 33 ± 5. 91) points, (57. 69±5. 27) points and (60. 69±5. 09) points,respectively,for the three groups,and the difference was significant( F=2. 62,P<0. 05). The scores on microscopic observation of the protozoan samples were respectively (33. 25±2. 98) points, (33. 60± 2. 85) points and ( 35. 29± 2. 17) points in the three groups,and the difference was significant( F= 5. 06, P<0. 05). Conclusion The assignment handed in by both hard copy and soft copy can improve the achievement in students in experimental course for Human Parasitology,especially,their ability in microscopic identification of the protozoan specimens.
