SLR Matrix Data Set - PjBL in TVET

This dataset contains a synthesis matrix of 67 international scientific articles related to Project-Based Learning (PjBL) in vocational and higher engineering education collected through a Systematic Literature Review process. Each article entry is documented in a structured format that includes bibliometric information (author, year, journal, DOI), educational context (TVET, engineering, vocational high school, STEM, ICT, CAD-CAM-CAE, civil/mechanical/electrical engineering), the soft skills studied (creativity, communication, collaboration, critical thinking, teamwork, leadership, problem-solving, digital literacy), and a summary of the research results and main findings. The variable categories in the dataset allow for analysis of PjBL research patterns, 21st-century skills development trends, and comparison of the effectiveness of implementation models across countries, educational levels, and engineering domains. This dataset can be used for meta-analysis, further systematic reviews, research gap mapping, and recommendations for developing project-based vocational learning models.
