THE CONSTRUCTION OF MATHEMATICAL PROBLEM-SOIVING PROCESS TEST FOR STUDENTS IN GRADE 9 IN THE OFFICE OF PROVINCIAL EDUCATION CHONBURI

Abstract

The purpose of this research is to create the examination for quality and intersection point of the mathematic problem solution strategy for grade 9 students in first semester year 2017 in Chonburi Education service area. They were two experimental groups, one group was teachers who analyzed the examination with 6 sample random sampling mathematic teachers, the other one group was 474 students who tested G*Power 3.1 by using Multi-Stage Sampling. The tools of this research were two mathematical problem-solution strategy tests were the multiple choices test and writing test. The both of research instruments were first tested with 150 students in grade10, and the experimental research with 314 students. The Results of study revealed that:

1. 1. After the experiment at IOC>0.5, the multiple choice 36 items ( =0.24-0.79, =0.47) and the next writing 9 items ( =0.60-0.64, =0.58), the students spent time average 90 minutes per tool.
2. 2. The multiple choices had difficulty values as 0.25-0.79, Discrimination value as 0.21-0.77, the writing test had difficulty values as 0.50-0.63, Discrimination values as 0.32-0. Validity values as Multiple choices=0.78, writing=0.82. Reliability values as multiple choices=0.93, writing=0.74, Reliability of teacher who analyzed the 2 examinations=0.99, the correlation of multiple choice and writing test and intersection score as 0.90 at significant 0.01.
3. 3. The first mathematical examination multiple choices had total score=36, intersection point=25.98 (72.17%) and the students who passed intersection of multiple choices examination=130 students and writing examination total score=90, intersection point=61.25 (68.06%) and the students who passed the writing examination=136 students.
