The effects of organizing mathematics learning activities by using metacognition in problem solving on mathematical problem solving ability and mathematics achievement of mathayomsuksa 4 students
Abstract:
The purposes of this research were to compare the student s mathematical
problem solving ability and mathematics achievement of mathayomsuksa 4 students after using
metacognition in problem solving with 70 percent achievement criterion. The subjects of this
study were 50 students in mathayomsuksa 4 in the second semester of the 2016 academic year at
Chonradsadornumrung school. They were randomly selected by using cluster random sampling.
The instruments were; 7 lesson plans, mathematical problem solving ability test (with reliability
of .96) and mathematics achievement test (with reliability of .85). The data were analyzed by
mean, standard deviation and t-test for one sample. The findings were as follows:
1. The mathematical problem solving ability of the sample group after obtaining
metacognition in problem solving was higher than 70 percent criterion at .01 level of statistical
significance. When considering mathematical problem solving ability of the sample group for
each stage, it was found that the ability in understanding the problem's stage, devising a plans stage, carrying out the plans stage and looking backs stage of the sample group was higher than the 70 percent criterion at .01 level of statistical significance.
2. The mathematics achievement of the sample group after obtaining metacognition
in problem solving was higher than the 70 percent criterion at .01 level of statistical significance.
