The target group of this research was 26 Mathayomsuksa 5 in the second semester of 2019 academic year from Sarakhampittayakhom school. The instruments were 3 lesson plan of Problem-based learning management, 3 lesson plan of Problem-based learning management with KWDL technique, 10 set of mathematical process test, the Mathematics behavior observation form. The data was analyzed by using mean, percentage and standard deviation.</p>
<p> The results of this research were following; after accomplished with 2 cycle of action research, the mathematical processes of all students in the target group had a score higher than the 70 percent of the full score. Considering in each cycle;</p>
<p> The first cycle using the Problem-based learning; there were 24 (92.31%) students passing 70 percent of full score. The students had an average score 22.92.</p>
<p> The second cycle using the Problem-based learning with KWDL technique; all of target group (26 students (100.00%)) passed 70 percent of full score. The students had an average score 24.42.</p>}, number={1}, journal={Journal of Roi Et Rajabhat University}, author={Jaitong, Natchata and Cojorn, Kanyarat}, year={2022}, month={Apr.}, pages={3–14} }
