Mathematical Activity Set Developing on Poya Solving Problem; Integer for Grade 7 Student

Abstract

Mathematical Activity Set Developing on Poya Solving Problem ;Integer for Grade 7 Student, the purposes of this study were to 1) develop and find out the efficiency the set Mathematical Activity Set Developing on Poya Solving Problem ;Integer for Grade 7 Student by the criterion at 80/80  2) compare the studying  achievement on using the set of Mathematical Activity on Poya Solving Problem ;Integer for Grade 7 Student between Pre-test  and Post -test. 3) study the students’ satisfaction to the instruction on using the set of Mathematical Activity on Poya Solving Problem; Integer for Grade 7 Student. The research was Experimental Research; One-Group-Pretest-Posttest Design. The  grade 7/1 of 40 sampling students who were studying in the first semester in 2021 of Phopphawitthayakom School in The Secondary Educational Service Area Office Tak by  purposive  sampling. The studying tools were 1. six sets of Mathematical Activity on Poya Solving Problem ;Integer for Grade 7 Student 1) integer  2) integer addition  3) integer deletion  4) integer multiplication 5) integer division and 6) property of Integer 2. achievement test and 3. satisfaction questionnaire, analyzing the data by using percentage  Dependent t-test and mean. The results were as follows: 1. The set of Mathematical Activity on Poya Solving Problem ;Integer for Grade 7 Student was higher than the criterion at 80/80; 80.78/82.95 2. The  studying achievement on the  Mathematical Activity Set on Poya Solving Problem ;Integer for Grade 7 Student ; Post –test  was significantly  higher  than  Pre – test  at  level .05 3) The students’ satisfaction to the instruction on using the Mathematical Activity Set on Poya Solving Problem ;Integer for Grade 7 Student was appropriate at highest level.
