The Effects Of Physics Web-Based Instruction Using Collaborative Learning In Group Investigations Technique To Enhance Analytical Thinking Of Grade X Students

Abstract
The objectives of this research were 1) to create the efficiency of the Physics Web-Based Instruction (WBI) using collaborative learning in group investigation technique to enhance Analytical Thinking of Grade X students, 2) to compare the Analytical thinking skill before and after using the Physics Web-Based Instruction using collaborative learning in group investigation technique and 3) to study the student�s satisfaction towards the Physics Web-Based Instruction using collaborative learning in group investigation technique to enhance Analytical thinking. The samples were forty of Grade X students of Demonstration School Khon Kaen University Thailand, were selected by simple random sampling. The instruments in this research were: 1) Physics WBI using collaborative learning in group investigation technique upon Analytical thinking of Grade X students entitle Linear Motion, 2) The Analytical thinking skills test for Grade X students entitle Linear Motion, and 3) The questionnaire of Grade X students� satisfaction towards Physics Web-Based Instruction. The statistics used in data analysis for this research were Mean, Standard Deviation and t-test. The results of this study were as follows: 1. The Physics Web-Based Instruction using collaborative learning in group investigation technique to enhance Analytical thinking of Grade X students, efficiency was 81.67/80.56. 2. The Analytical thinking skills of Grade X students, which using Physics Web-Based Instruction using collaborative learning in group investigation technique, was higher than before using with the statistically significant at the level .05. 3. The Grade X students� satisfaction towards the Physics Web-Based Instruction using collaborative learning in group investigation technique to enhance Analytical thinking of Grade X students was at �high� level.
