Project-Based Learning Combined with Inquiry-Based Learning Using Solver Tools to Promote Computational Thinking Among Undergraduate Students

This research aims to 1) Study the management of learning units on linear programming for undergraduate students, 2) Develop and verify the quality of the learning model, and 3) Examine the effects of the model on 24 undergraduate students at the Rajamangala University of Technology Suvarnabhumi using purposive sampling. This research was a research and development study. The research tools included the learning management model, lesson plans, classroom observation forms, and computational thinking assessment tools. Data were analyzed using percentage, mean, standard deviation, and t-test. The research findings were as follows: 1) The learning management was characterized by collaborative learning, studying, planning, practicing, expanding students' concepts to summarize mathematical concepts, and assessing the results. The instructor guided, stimulated learning, supported, facilitated, and reinforced learning. 2)The combined Project-Based Learning andInquiry-Based Learning model using Solver tools included principles, objectives, learning management processes, measurement and evaluation, and essential conditions for successful implementation. The model was of high quality with an effectiveness index of 0.561; 3)Implementing the model significantly increasedstudents' computational thinking skills in all five areas with a statistical significance level of 0.001.
