Abstract

The study aimed to assess the impact of the KWDL technique on the learning achievement of grade 9 students in quadratic function and their satisfaction with this instructional approach. Forty-four ninth-grade students from a Thai public secondary school participated, recruited by cluster random selection. The instruments comprised a KWDL learning management plan, an achievement test, and a satisfaction assessment. Data analysis involved mean scores, standard deviation, and a paired samples t-test. Results revealed significant differences between pre and posttest scores, alongside high levels of satisfaction with the method. The findings contribute to the field by demonstrating the effectiveness of the KWDL technique in teaching complex mathematical problem-solving concepts.
