An experimental study is adopted to evaluate the new teaching material. The experiment result shows the proposed teaching material based on Ontology concept outperforms the traditional one. Moreover, the research examined the subjects’ attitude with the questionnaire “Technology Acceptance” and found out that over 50% of learners considered the teaching material was easy to learn and useful in clarifying their misconceptions as well as helpful to their problem solving skills.
