The currently available measures of online teaching effectiveness (OTE) have several flaws, including a lack of psychometric rigor, high costs, and reliance on the construct of traditional on-the-ground teaching effectiveness as opposed to the unique features of OTE (Blackman, Pedersen, March, Reyes-Fournier, & Cumella, 2019). Therefore, the present research sought to establish a psychometrically sound framework for OTE and develop and validate a measure based on this clearly-defined construct. The authors developed pilot questions for the new measure based on a comprehensive review of the OTE literature and their many years of experience as online instructors. Students enrolled in exclusively online coursework and programs at Purdue University Global, N = 213, completed the survey, rating the effectiveness of their instructors. Exploratory Factor Analysis produced four clear OTE factors: Presence, Expertise, Engagement, and Facilitation. The resulting measure demonstrated good internal consistency and high correlations with an established OTE measure; good test-retest reliability; and predictive validity in relation to student achievement. Confirmatory Factor Analysis revealed a good fit of the data and yielded a final 12-item OTE measure. Further refinement and validation of the measure are recommended, particularly with students in other universities, and future research options are discussed. Keywords : online teaching effectiveness, instructor effectiveness, distance learning, student evaluations, asynchronous learning.

Purdue全球在线教学有效性量表的编制和验证

当前可用的在线教学效果(OTE)衡量方法存在一些缺陷,包括缺乏严格的心理测验,成本高以及依赖于传统的现场教学效果的构建,而不是OTE的独特功能(Blackman, Pedersen,March,Reyes-Fournier和Cumella,2019)。因此,本研究寻求为OTE建立心理上合理的框架,并基于此明确定义的结构开发并验证一种措施。作者基于对OTE文献的全面回顾以及他们作为在线讲师的多年经验,为新方法制定了试点问题。普渡大学全球(N = 213)专门参加在线课程和计划的学生完成了调查,对他们的老师进行了评分。探索性因素分析产生了四个清晰的OTE因素:存在,专业知识,敬业度和便利化。所产生的测度显示出良好的内部一致性,并与既定的OTE测度具有高度相关性;良好的重测可靠性;以及与学生成绩相关的预测效度。验证性因素分析显示数据很好,并得出了最终的12项OTE量度。建议进一步完善和验证该措施,尤其是与其他大学的学生一起,并讨论未来的研究方案。关键词:在线教学有效性,教师有效性,远程学习,学生评价,异步学习。所产生的度量显示出良好的内部一致性,并且与既定的OTE度量具有高度相关性;良好的重测可靠性;以及与学生成绩相关的预测效度。验证性因素分析显示数据很好,并得出了最终的12项OTE量度。建议进一步完善和验证该措施,特别是与其他大学的学生一起,并讨论未来的研究方案。关键词:在线教学有效性,教师有效性,远程学习,学生评价,异步学习。所产生的测度显示出良好的内部一致性,并与既定的OTE测度具有高度相关性;良好的重测可靠性;以及与学生成绩相关的预测效度。验证性因素分析显示数据很好,并得出了最终的12项OTE量度。建议进一步完善和验证该措施,尤其是与其他大学的学生一起,并讨论未来的研究方案。关键词:在线教学有效性,教师有效性,远程学习,学生评价,异步学习。建议进一步完善和验证该措施,尤其是与其他大学的学生一起,并讨论未来的研究方案。关键词:在线教学效果,教师效果,远程学习,学生评价,异步学习。建议进一步完善和验证该措施,尤其是与其他大学的学生一起,并讨论未来的研究方案。关键词:在线教学有效性,教师有效性,远程学习,学生评价,异步学习。
