碩士 === 國立交通大學 === 資訊科學與工程研究所 === 97 === The arithmetic word problem enables students to apply their arithmetic skills to solve the problem in application level arithmetic of Bloom’s taxonomy. However, it is costly and time consuming to construct new arithmetic word problems due to the complexity of combining the different arithmetic questions with the various and reasonable scenario. In this thesis, we aim to apply Folksonomy-Based approach to collecting teachers’ knowledge consisting of Question Scenario and Question Structure. We proposed an Arithmetic Word Problem Frame Hierarchy knowledge representation to represent these question structure because inheritance property of frames is appropriate to represent the category structure of arithmetic word problems. The proposed Arithmetic Word Problem Grammar can facilitate the maintenance of arithmetic word problems and their evolutions including Self-Evolution and Collaborative-Evolution. Self-evolution changes the arithmetic logic to generate different problems. And collaborative-evolution integrates two question structures into a new question structures. Besides, the rules embedded in the frame can be used to apply different scenario to the question structure; thus a large amount of arithmetic word problems can be generated. We have also constructed a Folksonomy-Based Item Bank management system (FIB) to evaluate the satisfaction degree of FIB. The evaluation results show that most of elementary school teachers satisfy with our proposed system.
