Learning Provision with KWDL Technique to Promote Mathematical Problem-solving and Reasoning Skills for Mathayom Suksa 3 Students, Baanpong School, Chiang Mai Province

This research aimed to explore Mathayom Suksa 3 students' mathematical problem-solving and reasoning skills and their opinions on learning provision with KWDL Technique. The target group was 25 students who enrolled in the first semester of the academic year 2013 from Baanpong School, Chiang Mai Province. The research instruments were lesson plans with KWDL Technique on the topic of area surface and volume (10 lessons), the mathematical problem-solving and reasoning skills test, and a survey of students' opinions on learning provision with KWDL Technique. In analyzing quantitative data, percentage, mean scores, and standard deviation were applied. In analyzing qualitative data, descriptive analysis was implemented.

Regarding to students' mathematical problem-solving skill based on Polya's process, students showed their skills on the processes of understanding the problem, making plans, and carrying out the plan were at high level. However, their skills on the process of checking the feasibility of answer were at fair level. Focusing on mathematical reasoning skill, the students could employ appropriate reason at good level. They also expressed positive opinions on learning provision with KWDL Technique in 3 dimensions, including learning provision, learning atmospheres, and usefulness of the learning activities.
