“互联网+课堂”环境下PBL教学效果探析

Analysis of PBL teaching effect under“Internet+Classroom”environment

目的:探析基于“互联网+课堂”环境下以问题为导向的教学法(Project-based Learning,PBL)对于提高学生学习兴趣、培养自主学习和独立思考能力的作用。方法:以医学检验导论课程为模板,试验组采用“互联网+课堂”环境下PBL教学(2018级学生),对照组采用“互联网+课堂”环境下传统教学(2017级学生),比较2组学生课程成绩与同一学年学生总成绩排名进行相关性检验及分析学生问卷调查结果。结果:试验组学生的课程成绩明显高于对照组学生(t=88.321,P<0.01);试验组学生课程成绩与同一学年学生总成绩排名不相关(r=0.106,P>0.05),对照组学生课程成绩与同一学年学生总成绩排名相关(r=0.720,P<0.01);学生对不同教学模式的应用效果评价:除“培养解决问题能力、课程安排”2个指标外,2组间其他指标比较差异均有统计学意义(P<0.05),即PBL教学模式明显优于传统教学模式;学生对任课老师的评价:2组在“强化自主学习技能、帮助学生开展批判性思维”等指标,差异有统计学意义(P<0.05)。结论:“互联网+课堂”背景下的PBL教学,完全具备PBL教学特点,其有助于提高学生成绩、提高学生学习兴趣、培养学生自主学习能力及团队合作精神和建立更加和谐的师生关系。

Objective:To explore the role of problem-based learning(PBL)in improving learning interest,cultivating independent learning ability and independent thinking ability of students under“Internet+Classroom”.Methods:Taking the introduction of medical laboratory as a template,students of grade 2018 in the experimental group received the PBL teaching method and students of grade 2017 in the control group received traditional teaching method.Correlation test was conducted to compare the academic performance of the two groups.The correlation of course performance and the ranking of students'overall academic performance in the same academic year,and the results of questionnaire survey were analyzed.Results:The course score of the experimental group was significantly higher than that of the control group(t=88.321,P<0.01).There was no correlation between the course scores of the experimental group and the total scores of the students in the same academic year(r=0.106,P>0.05).While,the results of the control group were highly correlated with the total scores of the students in the same academic year(r=0.720,P<0.01).The evaluation results of the application effect of different teaching methods showed that except for the two indicators of“cultivating problem-solving ability and curriculum arrangement”,the differences in other indicators between the two groups were statistically significant(P<0.05).The results of students'evaluation of teachers showed that there were differences between the two groups in five indicators such as“strengthening autonomous learning skills and helping students develop critical thinking”(P<0.05).Conclusion:PBL teaching in the context of“Internet+Classroom”can improve students'performance,increase students'learning interest,cultivate students'autonomous learning ability and team spirit,and establish a more harmonious relationship between teachers and students.
