Abstract
計算題為熟練工科力學課程經常採用的評量方式，也是學習者熟悉課程知識的方法之一，但卻很少有以大專工程教育課程計算題為教學主題的輔助教學系統。由於派翠西網路是一種很好的流程控制、模擬、診斷的工具，過去也有學者將其應用在數學解題知識的表達，藉由網路模型來偵測診斷學習者的觀念錯誤或學習障礙。因此，本研究之目的乃在於利用派翠西網路建構鋼筋混凝土設計學單筋矩形梁分析與設計單元的計算題解題知識流程，並利用派翠西網路的模擬與推理性為基礎，發展一套適當的即時解題障礙診斷策略，以提昇傳統計算解題輔助教學系統之教學互動性與解題彈性。
Calculation exercises are usually used in engineering courses to help students understand the problem-solving procedures. Also, engineering students are familiar with this kind of learning methodology. However, there are few computer aided systems to support students learning through calculation exercises. This research models the solving-procedures of Reinforced Concrete Design exercises using Petri-nets which are powerful tool for workflow control, simulation, and diagnosis. A diagnosis strategy is proposed based on the comparison between two networks of Petri-nets which are established to model both teacher’s and learner’s solving-procedures. A prototype of Petri-nets based computer aided system is presented to evaluate and demonstrate the diagnosis strategy and exercise tutoring process. The scope of exercises provided by the prototype system focuses on analysis and design of rectangular beams with tension reinforcement. An application example has been provided to demonstrate that proposed strategy can efficiently diagnose learner’s trouble via monitoring learner’s solving-procedures for a goal-oriented exercise.
