The Development of an Instructional Model for Chemistry Focus on Self-directed Learning to Promote Critical Thinking and Learning Achievement for Mathayom Suksa 4 Students

Abstract

This research aimed to 1) study the general information of learning management in science classes, 2) design and develop an Instructional Model focus on Self-directed learning, 3) apply the developed Instructional Model and 4) evaluate the developed Instructional Model by comparing the learning achievement between before and after classes and study the students’ satisfaction on the developed Instructional Model. This research was a research and development to promote critical thinking and learning achievement. The research participants were Mathayom Suksa 4 students who studied the Fundamental Chemistry in the first semester of academic year 2017 at Buakhoa School as an analyzed unit. The research results found that the model of learning management focused the self-directed learning process to promote critical thinking skills and learning achievement, the performance score was 83.61/81.11 and the index of effectiveness was 0.6989. The students’ learning achievement after learning with the developed Instructional Model was higher than before using it at the statistically significant level of .05. The satisfaction of the students, in general, was at the highest level. This research methodology consisted of 4 steps; 1) analysis of the existing teaching methodology, 2) development and finding the efficiency of the Instructional Model, 3) Implementation of the developed Instructional Model and 4) evaluation and improvement of the developed Instructional Model.
