Abstract

This exploratory mixed-methods study examined the experiences of first-year engineering students in integrating problem-based learning (PBL) and practical learning. It also explored how these experiences relate to students' self-efficacy, peer evaluation, and early academic adjustment. The study involved 16 first-year engineering students enrolled in two project-based courses. Quantitative analyses assessed the reliability and construct validity of self-, peer-, and team-evaluation instruments, while qualitative data from 32 semi-structured interviews were analyzed using thematic analysis. The qualitative findings revealed several recurring themes, including authentic engagement in problem exploration, collaborative idea development, peer interaction, and emerging academic confidence. Quantitative results showed a relatively strong alignment between self-assessment and peer-assessment scores, whereas the relationship between individual self-perceptions and team-level evaluations was more variable. Given the small sample size and single-institution context, these findings should be interpreted with caution. Nevertheless, the study offers valuable insights into how integrated PBL and practical learning environments may enhance collaborative engagement and knowledge application among first-year university students. The implications for instructional design and multi-source evaluation practices in project-based learning contexts are discussed.
