背景:展开的案例研究学习方法是在不同的卫生学科中实施的一种不断发展的现代化学习策略。然而,缺乏现有研究来检验高级护理课程中展开案例研究的效果。
目的:研究应用展开案例研究学习方法对重症监护护生知识的影响,批判性思维,和自我效能感。
方法:仅此后测,准实验研究在巴勒斯坦XXX大学进行。采用单阶段整群抽样将参加重症监护护理课程的护生分为实验组和常规组。干预组(n=91)接受了针对选定心血管主题的展开案例研究学习,而常规组(n=78)采用传统教学方法进行教学。后测评估是使用知识获取测试进行的,Yoon的批判性思维倾向工具(YCTD),以及学习和绩效工具的自我效能感。社会建构主义理论框架被纳入研究。
结果:两组在年龄、性别,和GPA。在测试后知识获取测试方面,实验组的得分明显高于常规组(7.12vs.5.49,分别t=-12.7,P<0.001,CI:-1.89至-1.38),批判性思维(4.32vs.分别为3.63,t=17.390,p<0.001,CI:-77至-61)和自我效能感(6.12vs.4.4分别t=-30.897,p<0.001,CI:-1.82至-1.60)。多因素分析显示,69%的后测分数变化受批判性思维分数的影响(调整后R平方=0.690,F=3.47,P=0002,η2=0.969)。同样,在进行研究计划后,自我效能感对得分差异的贡献为74%(调整后的R平方=0.743,F=4.21,P=0001,η2=0.974).然而,批判性思维和自我效能感得分的差异均不受知识获取的贡献(分别为p=0.772和0.857)和学生的GPA(分别为p=0.305和0.956)的影响。
结论:不考虑知识水平和GPA,展开的案例研究学习方法可以增强参加高级护理课程的学生的批判性思维和自我效能感。
BACKGROUND: The unfolding case-study learning approach is a growing modernized learning strategy implemented in different health disciplines. However, there is a lack of existing research that examines the effects of unfolding case studies in advanced nursing courses.
OBJECTIVE: To examine the impact of applying an unfolding case-study learning approach on critical care nursing students\' knowledge, critical thinking, and self-efficacy.
METHODS: This posttest-only, quasi-experimental study was conducted at XXX University in Palestine. A single-stage cluster sampling was used to assign nursing students enrolled in the critical care nursing course into experiment and conventional groups. The intervention group (n= 91) underwent unfolding case-study learning for selected cardiovascular topics, whereas the conventional group (n= 78) was taught using the traditional teaching methods. The posttest assessment was conducted using Knowledge Acquisition tests, Yoon`s Critical Thinking Disposition Instrument (YCTD), and the Self-Efficacy for Learning and Performance instruments. The Social Constructivist Theoretical Framework was integrated into the study.
RESULTS: Homogeneity was achieved between both groups concerning Age, Gender, and GPA. The experiment group scored significantly higher than the conventional group regarding the posttest knowledge acquisition tests (7.12 vs. 5.49, respectively, t=-12.7, P<0.001, CI: -1.89 to -1.38), critical thinking (4.32 vs. 3.63 respectively, t=17.390, p<0.001, CI: -77 to -61) and self-efficacy (6.12 vs. 4.4 respectively, t=-30.897, p<0.001, CI: -1.82 to -1.60). Multivariate analysis revealed that 69 % of the variations of posttest scores were influenced by critical thinking scores (Adjusted R Squared=0.690, F=3.47, P=0002, η2=0.969). Similarly, self-efficacy has been shown to contribute by 74 % to the variations of scores after conducting the study program (Adjusted R Squared=0.743, F=4.21, P=0001, η2=0.974). However, the variations of both critical thinking and self-efficacy scores were not significantly influenced by the contribution of knowledge acquisition (p=0.772 and 0.857, respectively) and students\' GPA (p=0.305 and 0.956, respectively).
CONCLUSIONS: Irrespective of knowledge level and GPA, the unfolding case-study learning approach can enhance the critical thinking and self-efficacy of students enrolling in advanced nursing courses.
