Portfolio is an innovative instrument that promotes reflection, creativity and professionalism among students.
To describe the development and validation process of a questionnaire to evaluate the use of portfolio in undergraduate medical students.
Focus groups with students and teachers were employed to identify aspects related with portfolio in undergraduate teaching. The Delphi technique was used to prioritize relevant aspects and construct the questionnaire. The validated questionnaire, consisting of 43 items and 6 factors, was applied to 97 students (response rote of 99.9%) in 2007 and 100 students (99.2%) in 2008. Each question had to be answered using a Likert scale, from 0 (completely disagree) to 4 (completely agree) The validity and reliability of the questionnaire was evaluated.
The questionnaire showed a high reliability (Cronbach alpha = 0.9). The mean total scores obtained in 2007 and 2008 were 106.2 ± 21.2 (61.7% of the maximal obtainable score) and 104.6 ± 34.0 (60.8% of the maximal obtainable score), respectively No significant differences were seen in the analysis by factors. Changes in portfolio during 2008 showed differences in items related with organization, evaluation and regulation.
The questionnaire is a valid and highly reliable instrument, measuring perceptions about the portfolio by undergraduate medical students. The students perceived an improvement in their creativity and professionalism as one of the strengths of portfolio. The weaknesses identified during the implementation process helped us to focus changes in organization and evaluation to improve the portfolio as a dynamic process.
学习档案袋是一种促进学生反思、创造力和专业素养的创新工具。
描述一份用于评估本科医学生学习档案袋使用情况的问卷的开发和验证过程。
通过与学生和教师进行焦点小组讨论，以确定本科教学中与学习档案袋相关的方面。采用德尔菲技术对相关方面进行优先级排序并构建问卷。经过验证的问卷由43个项目和6个因素组成，于2007年应用于97名学生（回复率为99.9%），2008年应用于100名学生（99.2%）。每个问题必须使用李克特量表回答，从0（完全不同意）到4（完全同意），并对问卷的有效性和可靠性进行评估。
该问卷显示出高可靠性（克朗巴哈α系数 = 0.9）。2007年和2008年获得的平均总分分别为106.2 ± 21.2（最大可获得分数的61.7%）和104.6 ± 34.0（最大可获得分数的60.8%），各因素分析中未发现显著差异。2008年学习档案袋的变化显示出与组织、评估和管理相关项目的差异。
该问卷是一种有效且高度可靠的工具，用于测量本科医学生对学习档案袋的看法。学生们认为学习档案袋的优势之一是他们的创造力和专业素养得到了提高。实施过程中发现的弱点帮助我们将组织和评估方面的改进重点放在学习档案袋上，使其成为一个动态过程。
