1.导论

MOOC（大规模开放在线课程）平台是一种受到广泛关注的新型在线教育模式，以其无论时间、空间、地域的限制，让学习者可以自由选择课程和学习方法，快速获取知识和技能，从而得到了广泛的应用和关注[1]。然而，MOOC平台也存在一些问题，如课程难度过高、作业量大、讨论不活跃等，影响学习者的学习兴趣和课程完成度，从而影响平台的教育效果和质量[2][3]。因此，探究MOOC平台质量对学习者课程完成度的影响，是提升MOOC平台教育质量和效果的重要方向。

2.文献综述

MOOC平台的发展已有多年，研究者也在这方面做出了许多探索和分析。Dror等[4]通过分析MOOC平台的特点和价值，探讨了开放的线上课程与传统教育的联系和差异；Yang等[5]通过量化分析和实证研究，找到了影响MOOC平台学习者完成课程的因素，并提出了提升完成度的策略；Raffaghelli等[6]则从MOOC平台的发展方向和未来发展趋势方面进行了深入探讨。同时也有一些研究关注MOOC平台的质量问题，比如Griffin等[7]通过分析MOOC平台的各个环节对课程完成度的影响，认为需要进一步优化平台的设计和交互方式来提升教育质量，提高学生的满意度.

3.研究方法

为了探究MOOC平台质量对学习者课程完成度的影响，本研究采用问卷调查法和实证分析法，通过对某著名MOOC平台上10门不同类型的课程进行调查，分析了平台质量和学习者课程完成度之间的关系。问卷主要内容包括学生个人特征、对平台质量的评价、参与度和完成度等因素。通过分析问卷结果，结合平台数据和课程分析，得出平台质量对学习者课程完成度的影响。

4.实证研究结果

4.1不同类别的课程对平台质量的需求不同

通过对不同类型课程平台质量的需求进行分析，得出了以下结果：知识性、实用性较强的课程，学生对于教材、视频、作业等方面的要求较高，包括清晰易懂的文字和图表，优质、精美的视频，具有针对性和实践性的作业。而难度较高的课程，学生对于课程的引导和支持较高，如导师和辅导员的指导和帮助，互助和互动平台的建立等。

4.2平台质量对课程完成度的影响

通过对数据的分析和对学生重新调查，发现平台质量对学习者的参与度和完成度均具有显著影响。平台越优质，学生的学习兴趣、动机和信心越高，参与度也越高，从而提升课程的完成度。本研究还发现，平台质量主要通过影响课程视频、难度、作业和讨论等方面影响学习者课程完成度。视频质量越好，作业量和难度适中，讨论活跃度越高，学习者的完成度越高。

5.结论和建议

本研究通过对中国某著名MOOC平台上10门不同类型的课程的调查和实证分析，得出了平台质量对学习者课程完成度的影响。研究结果表明，平台质量对于学生参与度和学习动机的增强，对于提高课程完成度具有明显的作用。因此，建议MOOC平台在提升课程质量和完成度方面，重点关注视频、难度、作业和讨论等方面，为学习者提供更优质、更有效的学习体验，推进MOOC平台的教育质量和效果的提升。
