雲端運算應用於試題分析與選題策略

想要了解平時學習的成效，考試測驗是很普遍且很有效的方法。考試除了測驗的分數之外，還有一些經計算後可得之判斷考生能力之數值，這些數值有些可經由簡單的運算後得出，但有些需經過複雜的運算後才可得，因其複雜的過程，使得有些人不去觀察這些數值，而只看測驗出來的分數，因此忽略了考試中其它項數據的重要性，像是考生之能力值與題目之參數如：試題鑑別度、猜測度與難度等等，導致未能有效的測驗出學習的成效。本研究將以即時且快速之特性，建構一套分析考試成績與策略選題之平台。此平台結合雲端運算提供快速以及可大量分析之特點。使用者無須了解各項欲得到數值之公式與程式碼，利用此平台即可完成需要之分析。此系統可讓使用者更快更方便的了解到考生之能力值，也可觀察試題之適合性，藉以更加有效了解考生之學習成效。平台中所提供之選題策略，使用者輸入欲得到試題難度，即可從本平台提供之選題策略中挑選題庫試題，得到適合欲測試考生之試題。

Examinations and tests are very common and effective ways to know the effects of learning. Besides, there are some values which can be obtained by simple arithmetic to judge the examinee's ability. However, there some values must be obtained through complex calculation. Because of its complexity, some people omitted those values and only observe the result of tests which caused them ignore the importance of the exam data such as the ability of the examinees and parameters of items including item discrimination, guessing and difficulty, which makes them can't obtained the effects of learning efficiently. This study will establish an analysis platform includes test results and strategic item choosing function based on its immediateness and its high-speed characteristic. This platform also combines the high-speed characteristic and calculated quickly of cloud computing, so that users do not need to know other codes or formulas about the results, they can get the outcomes easily with this platform. This system allows users knowing the ability of examinees faster and more convenient, and observing the compatibility of items in order to grasp more about the learning effectiveness of examinees.
