【摘要】 目的:基于《儿童少年卫生学》课程探讨以问题为基础的学习方法(PBL)教学对学生自主学习能力的影响,为完善PBL教学设计提供依据。方法:选取50名本科生为研究对象,对其开展3次《儿童少年卫生学》课程PBL教学,采用自编制的《学生自评问卷》评价学生自主学习能力,教师依据学生自主学习能力将其分为"普通""良好""优秀"三类,分不同类别比较3次PBL学生自评分的差异。结果:第2次PBL、第3次PBL教学自评总分、通过不同渠道收集资料的能力、语言表达和组织协调能力,归纳汇总结的能力条目评分均高于第1次PBL(P <0. 05～P <0. 01)。"普通""良好""优秀"学生在将生活相关或创新的意念与所讨论的案例相结合的能力、"良好"学生在通过不同渠道收集资料的能力条目评分第2次PBL均高于第1次和第3次PBL(P <0. 05～P <0. 01),而"良好"学生在积极参与的能力条目评分第3次PBL低于第1次、第2次PBL(P <0. 01)。结论:PBL教学有助于提升学生的自主学习能力,但伴随PBL教学次数的增加,学生自主学习能力未呈现持续上升趋势,应合理设置PBL教学频次及时间间隔。更多还原

【Abstract】 Objective: To investigate the effects of PBL on students’ self-learning ability based on child and adolescent health course,and provide the basis for improving PBL teaching design. Methods: The PBL teaching of child and adolescent health course was taught in 50 college students for three times. The students’ self-learning ability was evaluated using the Students’ self-evaluation questionnaire made by self. The self-learning abilities of students were divided into the general,better and best grades by teachers. The differences of students’ self-learning ability among the 3 times PBL teaching were analyzed. Results: The total scores of the " ability of collecting data by several methods", " abilities of language expression and organization",and " generalizing and summarizing abilities" of students in the second and third PBL teaching were higher than those in the first PBL teaching( P < 0. 05 to P < 0. 01). The scores of " ability of combining innovative idea or related life with teaching cases" in 3 groups,and " ability of collecting data by several methods" in students with better self-learning ability in the second PBL teaching were higher than those in the first and third PBL teaching( P < 0. 05 to P < 0. 01). The score of " ability of active taking part in PBL teaching" in students with better self-learning ability in the third PBL teaching was lower than that in the first and second PBL teaching( P < 0. 01). Conclusions: PBL teaching can improve the students’ self-learning ability. The students’ self-learning abilities do not increase with the increasing of PBL teaching time. The PBL teaching time and interval time should be reasonably set up.更多还原
