The Validation of Knowledge Construction Model based on Constructivist Approach to Support ILL-Structured Problems Solving Process for Industrial Education and Technology Students

Abstract

This research aimed to study the internal validation and the external validation of the knowledge construction model based on constructivist approach to support process in solving ill-structured problems. The samples were 42 fourth-year undergraduate students from the Department of Educational Communications and Technology, King Mongkut's University of Technology Thonburi. There were 3 experts to verify the quality of internal validation of the model. The research design was based on Type II developmental research. The result from the internal validation of the model showed that the design of components inside the model was in accordance with the principles and theories adopted in the design. The study of the external validation of the model showed that the learners followed steps of the process in solving ill-structured problems in accordance with Jonassen's principle (1997) in solving ill-structured problems. The learning achievement of students passed the criteria of 80 percent. The students' opinion showed that the learning contents, the media on the network and the design were suitable for supporting knowledge construction and process in solving ill-structured problems.
