abstract
- The effectiveness of the use of PhET educational simulators as didactic tools in the teaching of physics concepts was evaluated, comparing their effects on motivation and self-efficacy in engineering students when performing traditional laboratory practices since their impact on STEM disciplines, commitment, and understanding are crucial for academic success. The sample consisted of 236 first-year students divided into an experimental group using simulators and a control group that performed the practices in the physics laboratory. The Reduced Instructional Materials Motivation Scale (RIMMS) and the self-efficacy subscale of the MSLQ, translated and validated in Spanish, were used. The results showed that the experimental group exhibited a significant increase in motivation. No statistically significant differences were found in self-efficacy, suggesting that its impact on this aspect is limited and possibly requires more activities with simulators. This study concludes that simulators can complement and improve traditional practices, especially to increase student motivation. © 2025 by the authors.
