發明專利概念的由來，在於面對學校英語教學環境中，處於最底層的學生，這類的學生，對於英語的學習，基本上抱持著完全放棄的態度。在教學的方法上，如何引進正確的方法，引導學生對學習英語的興趣。在教學成果的驗收時，如何能正確的測驗出學生們，對老師所引進新的輔導教學方法，是否有較佳的學習成果。 本測驗設計的基礎技術核心，是引用統計學中亂數產生器RNG的理論，採用或然率的概念，在測驗題中，設計安排一定數量的測謊題，在試題答案的編排上，作亂數原理的安排，以此做爲測試結果評估的重要參數。如此可將同學們在答題時，因爲不了解題目，而採用猜題作答的結果排除。通常這種猜題作答的結果，常會誤導老師，對同學們實際的學習結果，作出誤判，進而影響老師對教學方法的修正。 本測驗方法的目的，並非將測驗的成績，列入學生們的學期成績中；因爲檢測的目的，只爲了幫助老師，評估學生們對英語學習教學的學習成果，減少老師對學生學習成果評估過程中，自由心證部分的壓力。

A patent is pending for an English testing technique using a Random Number Generator (RNG). The idea for this patent originated from the author's realization that low-level, unmotivated learners of English need to be taught using appropriate methodologies, and teachers of these students need an accurate method of testing the efficacy of whatever methodologies are used. In order to evaluate test scores objectively, all the guessed answer shall be eliminated, This is done by involving an RNG mechanism. RNG was used to create the answer name profile which was used to rearrange the test questions and to include some specially designed polygraph questions (PQ) to objectively evaluate the test and lower the probability of interference from guesswork. This study uses RNG to assess the learners' genuine learning outcomes, however, the testing results were excluded from students' academic scores. The purpose is only to provide the teacher concise and objective evaluation to be able to apply appropriate teaching methods with private individual guidance and consulting for students' successive learning.
