Development of Prathom Suksa 3 Students’ Problem-solving Skills in Solving Multiplication and Division by Using KWDL and Bar-drawing Technique

Abstract

The purposes of this research was to develop the skills in solving mathematical multiplication and division of Prathom Suksa 3 students by using KWDL and the bar-drawing technique. The target group was 25 Prathom Suksa 3 students in the second semester of 2012 the academic year of Ban Dongkhangkumton School under Ubon Ratchathani Educational Service Area 5. The research conducted five KWDL and bar-drawing technique lesson plans.  The research instrument was the problem-solving skills test.  Statistics were mean, percentage, standard deviation, and analysis of the efficiency of the lesson plans by using the criterion of E1/ E2 equal 70/70.

The research findings was as follows.

The learning managing steps to develop problem-solving skills consisted of the following : 1) introduction, 2) learning managing with a) presentation of the content b) group activities 3) free practice by learning procedures of four sub-steps, (1) K (2) W (3) D (4) L, including bar –drawing technique in K and W step 3) conclusion  4) measurement and evaluation. The learning managing steps with of students efficiency lesson plans could developed higher problem solving skill.
