The sample group consisted of 30 first-year undergraduate students in Mathematics who enrolled academic year 2020 from Faculty of Sciences and Technology, Surindra Rajabhat University. Research tools consist of learning activities using GeoGebra program to support a problem-based learning activity, an achievement test, and a questionnaire towards satisfaction on learning activities. Basic statistical devices used for data analysis were percentage and standard deviation. A research hypothesis was tested using T-distribution. The study found that: 1) The efficiency of learning activities for mathematical problem-solving using GeoGebra program to support a problem-based learning activity was 77.75/75.33. 2) The students that learned to solve mathematical problems through learning activities using GeoGebra program to support a problem-based learning activity have a higher score after studying than before at .05 of significant level. 3) The overall satisfaction towards learning activities is at the highest level.</p>}, number={8}, journal={Journal of MCU Nakhondhat}, author={Sichiangha , Aruntida and Soijit , Pradidchaya and Chansaengkrachang, Kosum}, year={2021}, month={Jul.}, pages={31–42} }
