Instructional strategies must be balanced when subjecting students to full-immersion simulation so as not to discourage learning and increase cognitive overload. The purpose of this study was to determine if participating in a simulation exercise before lecture yielded better performance outcomes among novice learners.
Twenty-nine participants were divided into 2 groups as follows: group 1 participated in simulation exercises followed by a didactic lecture and group 2 participated in the same learning activities presented in the opposite order. Participants were administered a multiple-choice cognitive assessment upon completion of a workshop.
Learners who participated in the simulated exercises followed by the didactic lecture performed better on postassessments as compared with those who participated in the simulation after the lecture. A repeated-measures or nested analysis of variance generated statistically significant results in terms of model fit F (α=0.05; 4.54)=176.07 with a P<0.0001. Despite their higher levels of increased performance, 76% of those who participated in simulation activities first indicated that they would have preferred to participate in a lecture first.
The findings of this study suggest that differences occur among learners when the sequencing of instructional components is altered. Learners who participated in simulation before lecture demonstrated increased knowledge compared with learners who participated in simulation after a lecture.
在让学生进行全沉浸式模拟时,教学策略必须保持平衡,以免抑制学习并增加认知负荷。本研究的目的是确定在讲座前参与模拟练习是否会使新手学习者取得更好的学习成果。
29名参与者被分为两组,如下所示:第一组先参与模拟练习,然后参加理论讲座,第二组以相反的顺序参与相同的学习活动。在完成一个研习班后,对参与者进行多项选择认知评估。
与在讲座后参与模拟的学习者相比,先参与模拟练习然后参加理论讲座的学习者在课后评估中的表现更好。重复测量或嵌套方差分析在模型拟合F(α = 0.05;4.54)= 176.07方面产生了具有统计学意义的结果,P < 0.0001。尽管先参与模拟活动的学习者成绩提高幅度更大,但其中76%的人表示他们更愿意先参加讲座。
本研究结果表明,当教学内容的顺序改变时,学习者之间会出现差异。与在讲座后参与模拟的学习者相比,在讲座前参与模拟的学习者知识有所增加。
