生物化学文理合班教学质量的调查与教学改革探讨

摘要

目的 探讨生物化学文理合班教学合理性,以进一步提高教学质量.方法 以2013级七年制中医学专业文理科合班教学学生共138人为研究对象,其中文科生58人、理科生80人.生物化学授课结束后开展问卷调查,主要包括学生对教学效果和教学改革的评价;发出问卷138份,收回有效问卷138份.同时针对文理科学生统一实施闭卷考试.采用SPSS 19.0对两类学生相关数据行t检验、卡方检验或确切概率法比较.结果 ①问卷调查:31.03％(18/58)的文科生和27.50％ (22/80)的理科生认为课时量偏少;48.28％(28/58)的文科生认为化学基础薄弱是影响学习的主要因素,50.00％(40/80)的理科生认为学习兴趣的缺失是首要因素;文理科学生均认为物质的代谢反应是最大的难点;51.72％ (30/58)的文科生和42.50％(34/80)的理科生支持以板书为主的教学方法.②考试成绩:文理科生的平均成绩分别为(70.81±9.71)分和(77.05±8.46)分,差异有统计学意义(t=-4.02,P=0.000).结论 问卷调查结果和考试成绩分析可见,文理合班教学具有可行性.但需通过加强学生化学基础、提高其学习兴趣和优化其学习方法等途径,实现文理科学生的协调发展和提升整体教学水平.%Objective To study the rationality of biochemistry teaching of liberal arts students and science students in one class and further to improve the quality of teaching.Methods A total of 138 students of seven-year traditional Chinese medicine of Grade 2013 as the objects of study,among whom there were 58 liberal arts students and 80 science students.Questionnaire were surveyed at the end of the teaching of biochemistry,including evaluation of the teaching effect and teaching reform.138 valid questionnaires were dispatched and recovered.And at the same time unified examination was carried out to both liberal arts students and science students.The t test,chi square test or the exact probability method were used to compare the data of two types of students with SPSS 19.0.Results Questionnaire survey:31.03％ (18/58) arts students and 27.50％ (22/80) science students felt that the class hours were not enough.48.28％ (28/58) arts students thought the weak chemical base to be the main factor affecting learning,and 50.00％ (40/80) science students thought that lack of interest was the most important factor.53.45％ (31/58) arts and 47.50％ (38/80) science students would agree that a metabolic reaction of the material was the most difficult problem.51.72％ (30/58) arts students and 42.50％ (34/80) science students preferred blackboard-writing.Test scores:arts and science students got average grades (70.81 ± 9.71) and (77.05 ± 8.46) respectively,and the difference was statistically significant (t=-4.02,P=0.000).Conclusions Survey results and analysis of test scores shows that teaching of liberal arts students and science students in one class is feasible.However,it is necessary to strengthen the students' chemical basis,improve their learning interest and optimize their learning methods,so as to realize the harmonious development of the students of arts and science,and to improve the overall teaching level.
