중학생의 심폐소생술 교육에 어떤 방법이 효과적인가?

Abstract

This study is an equivalent experimental study to compare and verify the ed ucational effects of three learning methods for CPR such as music video self-in struction, video self-instruction and conventional instructor-led instruction. Subjects of this study were 126 third graders of S Middle School in G metro politan city, who agreed to participate in this study under informed consent by documented form and then randomly allocated to 3 experimental groups, 36 of music video self-instruction group(Exp A), 35 of video self-instruction group(Exp B), and 30 of instructor-led instruction group(Exp C), respectively. The period of study was three day from Sept. 7 to 9, 2009. As a results of analysis, Chi-square test, paired t-test, ANOVA(Scheffe post-hoc test) by statistical package SPSS ver. 12.0, major research findings were as follows; 1. three groups were homogeneous in sex, baseline values of outcome measures such as knowledge, self-efficacy, accuracy of technique performance. 2. the score of knowledge about CPR significantly increased after instruction in all 3 groups(p<0.001, respectively). Regarding mean difference in the score before and after CPR instructions, Exp A(7.50±2.84) was significantly higher than Exp C(5.60±2.41)(p=0.018). 3. self-efficacy towards CPR significantly increased after instruction in all 3 groups(p<0.001, respectively). Regarding mean difference in self-efficacy before and after CPR instructions, Exp A(2.18±0.56) and B(1.97±0.57) were significantly higher than Exp C(1.58±0.67)(p<0.001). 4. the accuracy of technique performance significantly increased after instruction in all 3 groups(p<0.001, respectively). Regarding mean difference in that before and after CPR instructions, Exp A(10.91±2.07) was significantly higher than Exp C(8.56±3.67)(p=0.004). 5. regarding the satisfaction with instruction, Exp A(3.82±0.65) and Exp B(3.53±0.78) were significantly higher than Exp C(2.74±0.68)(p<0.001). In conclusion, as CPR learning method for middle school students, music video self-instruction was the most effective in improving all outcome measures.
