Development of Mathematical Learning Management with KWDI Technique on Problems of Addition, Subtraction, Multiplication, Division to Enhance Achievement and Problem Solving Skills for Students in Grade 2
Abstract:
Development of mathematics learning management with KWDL technique on problems of addition, subtraction, multiplication, division to enhance learning achievernent and problem solving skills for Students in Grade 2. Objective 1) To develop a leamning managemnent plan on the problem of adding, subtracting, multiplying, and dividing people for Students in Grade 2 with KWDL technique 2) To compare the learning achievement on the problem of adding, subtracting, multiplying and dividing people for Students in Grade 2 before and after receiving the learning management with KWDL technique 3) To compare problem solving skills on addition, subtraction, multiplication and division problems for Students in Grade 2 before and after receiving the KWDL learning management technique. The target group was Students in Grade 2 at Ban Chang Ku Rueang School, Phrao District, Chiang Mai Province, for the second semester of the academic year 2021. 25 students were selected by selective method. The research tools consisted of 1) Plan of learning activities using KWDL technique 2) Achievement test. Before and after learning activities using KWDL technique on solving addition, subtraction, multiplication and division problems; and 3) problem solving skills test. Mathematics Problem Solving Addition, Subtraction, Multiplication, and Division. The results of the research were as follows: 1) Plans for learning activities using the KWDL technique, it was found that the appropriateness was at a high level 2) the comparison of the learning achievemnent before and after the leaming with the KWDL technique It was found that the academic achievemnent after school had higher average scores than before. They had an average score of 9.56 and an average score of 17.2 after studying. 3) Comparative results of problem solving skills Before and after receiving the KWDL learning management technique, it was found that after studying, the average scores were higher than before. Before studying, the average score of 4.72, after studying, the average score of 8.64
