การพัฒนาผลสัมฤทธิ์ทางการเรียนและความสามารถในการแก้โจทย์ปัญหาทางคณิตศาสตร์ของนักเรียนชั้นมัธยมศึกษาปีที่ 1 โดยใช้การจัดการเรียนรู้แบบอุปนัยร่วมกับกลวิธี STAR
Abstract:
ABSTRACT
The research aimed to compare: 1) the mathematical learning achievement; and 2) the mathematical problem-solving ability of grade 7 students before and after learning using inductive learning management with the STAR strategy, and after learning with the set criteria. The sample, derived by cluster sampling, consisted of 22 grade 7 students who were studying in the second semester of the academic year 2019 at Ban Nong San Trea School,
Don Chedi District, Suphan Buri Province. The research instruments were: 1) the lesson plans based on inductive learning management with STAR strategy, which consisted of six steps:
1) identify the limitation of data, 2) collect and enumerate data, 3) examine data, 4) form concepts by classifying data, 5) determine relationships and investigate hypotheses, and
6) consolidate and transfer; 2) the mathematics achievement test; and 3) the mathematical problem solving ability test, which were assessed according to academic criteria and were at an acceptable level. The data were analyzed with percentage, mean, standard deviation, and t-test.
The results of this research were as follows:
1. The mathematical learning achievement of grade 7 students after learning
using inductive learning management with STAR strategy was higher than that of before, as well as higher than the set criteria of 80% with statistical significance at .05 level.
2. The mathematical problem solving ability of grade 7 students after learning
using inductive learning management with STAR strategy was higher than that of before, as well as higher than the set criteria of 80% with statistical significance at .05 level.
