The Effect of Computer-Assisted Instruction and Initial Knowledge on CNC Machinery Technique Learning

摘要

The objective of this research is to examine the effect of computer-assisted instruction and initial knowledge on student’s CNC Machinery Technique Learning. This research used 2×2 level design treatments. There are 2 types of computer-assisted instruction designs; Branchingand Linier used as treatment and achievement test CNC Machining Techniques which are used as a research instrument. The data were analyzed by using two-way Analysis of Variance (ANAVA). The result shows that there is a significant difference on student’s learning outcomes between usingBranching CAI and Linier CAI. The Tukey test shows that there are significant differences between Branching CAI and Linier CAI to students who have a high level of initial knowledge, but there is no significant difference to the students with low initial knowledge.
