Every procedural skill consists of some microskills. One of the effective techniques for teaching a main procedural skill is to deconstruct the skill into a series of microskills and train students on each microskill separately. When we learn microskills, we will learn the main skill also. This model can be beneficial for tuition on procedural skills.
In this study, we propose a stationed-based deconstructed training model for tuition of each microskill, and then we assessed the medical students' self-perceived abilities.
This quasi-experimental study was conducted in 268 medical students (536 matched pre- and post-questionnaires) at the surgical clerkship stage during five consecutive years in three teaching and learning groups. In this study, we taught each skill in 10 steps (proposed model) to the students. We then evaluated the students' self-perceived abilities using a pre- and post-self-assessment technique. SPSS v13 software with one-way analysis of variance and paired t-tests were used for data collection and analysis.
Assessment of medical students' perceived abilities before and after training showed a significant improvement (P < 0.001) in both cognitive and practical domains. There were also significant differences between the three teaching and learning groups (P < 0.001). There were no significant differences for the different years of training regarding the observed improvement.
This study suggests that deconstructing the practical skills into microskills and tuition of those microskills via the separated structured educational stations is effective according to the students' self-ratings.
每项操作技能都由一些微技能组成。教授一项主要操作技能的有效方法之一是将该技能分解为一系列微技能,并分别对学生进行每项微技能的训练。当我们学习微技能时,我们也将学会主要技能。这种模式对操作技能的教学可能有益。
在本研究中,我们提出一种基于站点的分解训练模式来教授每项微技能,然后评估医学生的自我感知能力。
这项准实验研究在连续五年中对三个教学组处于外科实习阶段的268名医学生(536份配对的前后调查问卷)进行。在本研究中,我们按照10个步骤(提出的模式)向学生教授每项技能。然后我们使用自我评估前后技术评估学生的自我感知能力。使用SPSS v13软件进行单因素方差分析和配对t检验来收集和分析数据。
对医学生训练前后感知能力的评估显示,在认知和实践领域均有显著改善(P < 0.001)。三个教学组之间也存在显著差异(P < 0.001)。不同年份的训练在观察到的改善方面没有显著差异。
本研究表明,根据学生的自我评分,将实践技能分解为微技能并通过单独的结构化教育站点教授这些微技能是有效的。
