This case study explored effective instructional strategies and technology use in blended learning (BL) in a graduate course in the USA. Varied forms of data were collected, including (1) semi-structured interviews with students, (2) mid-term and final course evaluations, (3) two rounds of online debates, (4) four weeks of online reflection journals, and (5) the instructor's reflections. Thematical analysis and descriptive statistics were conducted to analyze qualitative and quantitative data respectively. Multiple methods were employed to establish trustworthiness of the study. Effective and ineffective instructional strategies and technology uses were identified in BL. The findings indicated that students valued real-time interactions with peers and the instructor. However, inappropriate asynchronous discussions were considered less effective in BL. In addition, immediate feedback from peers and the instructor motivated learners and improved the quality of their work. Learning technologies played a critical role in BL, but the use of learning technologies should be simplified and streamlined. Technical support was essential to reduce learners' cognitive load.
本案例研究探讨了美国一门研究生课程中混合式学习(BL)的有效教学策略和技术应用。收集了多种形式的数据,包括:(1)对学生的半结构化访谈;(2)课程中期和期末评估;(3)两轮在线辩论;(4)四周的在线反思日志;以及(5)教师的反思。分别采用主题分析和描述性统计对定性和定量数据进行分析。采用多种方法来确保研究的可信度。确定了混合式学习中有效和无效的教学策略及技术应用。研究结果表明,学生重视与同伴和教师的实时互动。然而,在混合式学习中,不适当的异步讨论被认为效果较差。此外,同伴和教师的即时反馈激发了学习者的积极性,提高了他们的作业质量。学习技术在混合式学习中起着关键作用,但学习技术的使用应简化和优化。技术支持对于减轻学习者的认知负担至关重要。
