The data is collected from 35 students Grade 9 room 8.The research methodology is the lesson plan of statistics, the achievement test, the mathematical solving test and the satisfaction of studying test. The percentage, mean, standard deviation and t-test are applied as the data analysis tools.</p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The research results are here is that the KWDL technique in statistics lesson for Grade 9 students is effective with score 84.07/80.93 (E1/E2) above the criterion, Grade 9 students who follow KWDL technique tend to have better score with significant 0.05, and also perfectly satisfy in learning with KWDL technique.</p>}, number={2}, journal={Journal for Developing the Social and Community }, author={Sadod, Monthicha}, year={2020}, month={Dec.}, pages={263–274} }
