Results of Problem-Based Learning Management Activities with SQRQCQ strategy on Interest and Value of Money in Mathematical Problem Solving and Connection Abilities of Grade 11 Students

Abstract

The purposes of this research were 1) to compare the mathematical problems solving ability on “Interest and Value of Money” of grade 11 students after learning from activities management based on problem - based with SQRQCQ strategy with the criterion of 70 percent. 2) to compare the mathematical connecting ability on “Interest and Value of Money” of grade 11 students after learning from activities management based on problem - based with SQRQCQ strategy with the criterion of 70 percent. The sample was 39 students of grade 11 in the second semester of 2019 academic school year at Bangmod Wittaya School in Bangkok. They were selected by cluster random sampling. The research instruments used in this research were consisted of 1) six lesson plans, and 2) mathematical problems solving and connection abilities test on “Interest and Value of Money” (with reliability of .95). The data was analyzed by using means, standard deviation and t-test for one sample. The results of research were; 1. The mathematical problem solving ability on “Interest and Value of Money” of grade 11 students after learning from activities management based on problem - based with SQRQCQ strategy was higher than the 70 percent criterion at the .05 level of significance. 2. The mathematical connecting ability on “Interest and Value of Money” of grade 11 students after learning from activities management based on problem - based with SQRQCQ strategy was higher than the 70 percent criterion at the .05 level of significance.
