Effects of organizing mathematics learning activities using 4E×2 instructional model on mathematical concept and problem solving ability of ninth grade students
Abstract:
To compare the mathematical concepts and problem solving abilities of ninth grade students in an experimental group which was taught by using mathematics learning activities using 4E×2 instructional model, and those in a control group which was taught by using mathematics learning activities organized according to a conventional approach. The population of this research was the ninth grade students in schools under The Secondary Education Service Area Office 2, Office of the Basic Education Commission, Ministry of Education. The subjects were 88 ninth grade students of Sripruetta School in first semester of academic year 2011. There were 43 students in the experimental group and the other 45 in the control group. The experimental group was taught by using 4E×2 instructional model and the control group was taught by the conventional method. The research instruments were tests of mathematical concepts and mathematical problem solving abilities in Surface Area and Volume. The experimental materials were lesson plans using 4E×2 instructional model and conventional lesson plans. The data were analyzed by means of arithmetic mean, standard deviation, and t-test. The results of the research revealed that: 1. Mathematical concepts of ninth grade students being taught by using mathematics learning activities according to 4E×2 instructional model were higher than those of students being taught by using conventional approach at a .05 level of significance. 2. Mathematical problem solving abilities of ninth grade students being taught by using mathematics learning activities according to 4E×2 instructional model were higher than those of students being taught by using conventional approach at a .05 level of significance.
