The aim of this research was to develop and validate the (QAEP), an instrument designed to gather students' views about four dimensions of educational podcasts: access and use, design and structure, content adequacy, and value as an aid to learning. In study 1 we gathered validity evidence based on test content by asking a panel of experts to rate the clarity and relevance of items. Study 2 examined the psychometric properties of the QAEP, including confirmatory factor analysis with cross-validation to test the factor structure of the questionnaire, as well as item and reliability analysis. The results from study 1 showed that the experts considered the items to be clearly worded and relevant in terms of their content. The results from study 2 showed a factor structure consistent with the underlying dimensions, as well as configural and metric invariance across groups. The item analysis and internal consistency for scores on each factor and for total scores were also satisfactory. The scores obtained on the QAEP provide teachers with direct student feedback and highlight those aspects that need to be enhanced in order to improve the teaching/learning process.
本研究的目的是开发并验证质量评估教育播客问卷（QAEP），这是一种旨在收集学生对教育播客四个维度看法的工具：获取与使用、设计与结构、内容充分性以及作为学习辅助工具的价值。在研究1中，我们通过让专家小组对项目的清晰度和相关性进行评分，收集了基于测试内容的效度证据。研究2考察了QAEP的心理测量特性，包括进行交叉验证的验证性因素分析以检验问卷的因素结构，以及项目和信度分析。研究1的结果表明，专家们认为这些项目措辞清晰且内容相关。研究2的结果显示出与潜在维度一致的因素结构，以及不同组之间的构型和度量不变性。每个因素得分和总分的项目分析及内部一致性也令人满意。QAEP获得的分数为教师提供了直接的学生反馈，并突出了那些为改进教学/学习过程而需要加强的方面。
