Data Analysis Process of the Study: Key Information Summary, Dimensional Analysis, and Content Analysis

The data analysis process of this study involved three stages: key information summary, dimensional analysis, and content analysis.<b>Key Information Summary:</b> This phase focused on summarizing the key information of the literature. The content summary method was utilized to distill the main content, research themes, findings, and contributions of the literature, laying the foundation for subsequent in-depth analysis. Tables 3, 4, 5, 6, 7, and 8 were formed during this stage. Specific details of the tables are provided in the attachment.<b>Dimensional Analysis:</b> In this stage, thematic analysis was used to extract and identify key concepts and themes from the literature, exploring the relationship between self-directed learning (SDL) and deep learning. Tables 9 and 10 were formed during this stage.<b>Content Analysis:</b> The focus of this stage was on exploring how students experience and achieve deep learning within Self-Directed Learning. Content analysis aimed to deeply understand students' learning experiences, the learning strategies they adopt, and how these strategies facilitate deep learning. Tables 11 and 12 were formed during this stage.<b>Attachments:</b> Attach tables 3, 4, 5, 6, 7, 8, 9, 11, and 12 to the project for reference and further analysis.<br><br>
