Mobile Learning for Review on One Variable Linear Equation of Mathematics Subject for Grade7 Students

Abstract

ract
The purposes of this research were to ; 1) develop and find out the efficiency of Mobile Learning
for Review on One Variable Linear Equation of Mathematics Subject and 2) compare learning achievement
before and after learning with Mobile Learning for Review on One Variable Linear Equation.
The sample of the study comprised grade 7 students the academic year 2016 at Sainampeung Under
the Royal Patronage of Princess Petcharat Rajsuda Sirisopaphannawadee school, selected by Cluster
Random Sampling and divided into two groups. The first group was to find the efficiency of learning
management and the second group was to find learning achievement. The instruments of this research
were consisted of Mobile Learning for Review on One Variable Linear Equation of Mathematics Subject,
the qualitative evaluation form of Mobile Learning for Review and the achievement test to find the
accomplishment of learning. The analysis of the achievement test to find index of congruency (IOC)
resulted to the value of 1.00, the difficulty level between 0.20-0.79, the discrimination value between
0.20-0.79, the reliability was 0.86. Prior to students performed the experiment, the pretests were
administered. Then, the students proceeded to study Mobile Learning for Review on One Variable
Linear Equation of Mathematics Subject, and took sub-tests after studying each topic. When they
finished all topics, the posttests were administered. The data were analyzed by mean, standard
deviation and t-test for dependent sample.
The research result were as follow;
1. Mobile Learning for Review on One Variable Linear Equation of Mathematics Subject had
the efficiency of lesson equal to 86.00 : 94.00 which met the standard criteria of 80 : 80.
2. The result of learning achievement was concluded that posttest scores were significantly
higher than pretest scores of subjects learning with Mobile Learning for Review on One Variable Linear
Equation of Mathematics Subject at 0.05 levels.
