網際網路與電腦科技的進步,人們的學習由現實生活提升到了虛擬的空間中,應用虛擬的特性讓平常需到實驗室才有辦法進行的物理實驗或化學實驗,透過電腦的計算及重覆利用的特性在網路上讓學生進行學習與操作,因此發展出了虛擬實驗環境。 虛擬實驗在發展上主要以操作為主,也就是網頁教材搭配固定的實驗流程,利用程式工具實作出物理方面或化學方面的虛擬實驗教材,但這樣的實驗並無針對學生的操作做行為紀錄,所以無法去針對學生在實驗中所發生的一些錯誤的操作做導正或診斷的動作。 本研究提出針對虛擬實驗過程進行協助與診斷的理論,利用派翠網路的傳遞規則特性將實驗的步驟化成派翠網路模組,將學生的操作行為以知識指令做為紀錄的格式,並以該操作紀錄和標準實驗步驟做比較以得知學生在操作上的問題,在實驗過程中提供學生提示或協助,協助學生完成實驗。
Learning environment is made progress along with the development of network and computing technology .Physical and chemical experiments are able to be processed on the virtual environment through fast computation abilities and reuse of computers. That is the reason why the virtual experiment environment is proposed. The virtual experiment relies mainly on operating in developing. That is, using the webpage and regular experiment procedure, utilizing the program tool to implement physics or chemicals virtual experiment learning materials. But, the student's operations in the experiment process are not recorded. The mistakes of student's operations in the experiment process can not be diagnosed. In this thesis, the theory which offers aids and diagnosis during the virtual experiment process is proposed. The experiment steps are transformed into petri net model by using transmission rules of the petri net. Operating steps of the students are recorded in the form of knowledge instructions. Student's experiment steps are compared with standard experiment steps in order to diagnose and offer experiment suggestion.
