Academic achievement after school. It was statistically significantly higher than before studying at .05 level and the students’ analytical thinking ability was 25.52 score, 85.07% and the percentage of students who passed the criteria 80% or more was 100 94.79 each. 4) Evaluation results for using a research and development model, and revising a set of learning activities Mathayomsuksa 2/4 students are satisfied. Continue learning with a series of learning activities about economics, worth knowing Overall, they were satisfied at the highest level.</p>}, number={8}, journal={Journal of MCU Nakhondhat}, author={Aupakaeo, Suchanya}, year={2021}, month={Jul.}, pages={191–209} }
