Student engagement in a blended learning environment is very different from that in a traditional classroom environment, and is fostered by satisfying three innate needs identified in self-determination theory (SDT): autonomy, relatedness, and competence. Related studies have emphasized teacher support to satisfy the three students’ need, but not digital support. The founders of SDT recently stated that SDT-based research should focus on problems associated with learning technologies. Accordingly, this study proposed digital support designs to fulfill the three abovementioned needs, examined their effectiveness, and investigated how the developed forms of digital support and teacher support contributed to student engagement. The study adopted a sequential explanatory mixed methods research design and involved 426 Grade 11 students. The findings were as follows. (i) Compared with teacher support, digital support better engaged students in blended learning by satisfying their needs. (ii) Teacher support was closely related to student engagement. (iii) The relationship between digital support and student engagement varied. Possible explanations are the benefits of offering multiple modalities, considering learning expertise, and applying emotional designs. The findings contribute to SDT by adding a new perspective, namely digital support, and thereby proposing a new framework for needs support in blended learning.

学生在混合学习环境中的参与与传统课堂环境中的非常不同，它是通过满足自决理论 (SDT) 中确定的三个先天需求来培养的：自主性、相关性和能力。相关研究强调教师支持以满足三名学生的需求，但不强调数字支持。SDT 的创始人最近表示，基于 SDT 的研究应该关注与学习技术相关的问题。因此，本研究提出了满足上述三个需求的数字支持设计，检查了它们的有效性，并调查了数字支持和教师支持的发展形式如何促进学生参与。该研究采用顺序解释混合方法研究设计，涉及 426 名 11 年级学生。结果如下。(i) 与教师支持相比，数字支持通过满足学生的需求更好地让学生参与混合学习。(ii) 教师支持与学生参与密切相关。(iii) 数字支持与学生参与之间的关系各不相同。可能的解释是提供多种模式、考虑学习专业知识和应用情感设计的好处。这些发现通过增加一个新的视角（即数字支持）为 SDT 做出了贡献，从而为混合学习中的需求支持提出了一个新框架。(iii) 数字支持与学生参与之间的关系各不相同。可能的解释是提供多种模式、考虑学习专业知识和应用情感设计的好处。这些发现通过增加一个新的视角（即数字支持）为 SDT 做出了贡献，从而为混合学习中的需求支持提出了一个新框架。(iii) 数字支持与学生参与之间的关系各不相同。可能的解释是提供多种模式、考虑学习专业知识和应用情感设计的好处。这些发现通过增加一个新的视角（即数字支持）为 SDT 做出了贡献，从而为混合学习中的需求支持提出了一个新框架。
