Abstract: This study aimed to develop and evaluate an instructional model that integrates Microsoft Excel’s Solver into the engineering design process to enhance critical thinking and innovation skills among undergraduate engineering students. Addressing the need for graduates with strong problem-solving abilities, the study introduced a technology-enhanced learning approach grounded in real-world engineering tasks. Using a Research and Development (R&D) methodology, the study involved 30 students from an Optimization Analysis course, selected through purposive sampling. The instructional model combined Solver with the engineering design process to solve linear programming problems. Research instruments included a lesson plan, critical thinking and innovation assessments, behavior observation checklists, and a learner satisfaction survey. Quantitative data were analyzed using descriptive statistics, paired t-tests, and reliability analysis, while qualitative data were examined through content analysis. Results showed a significant improvement in students’ critical thinking and innovation skills after the intervention (p < .05). Observations revealed active engagement, analytical thinking, and creative problem-solving. Students also reported high satisfaction with the learning experience. In conclusion, integrating Solver into the engineering design process effectively promotes critical thinking and innovation. This model offers practical value for educators seeking to enhance active, student-centered learning with digital tools in engineering education.
