Abstract

For a basic engineering education the confirmation and verification of the deductive Inference was studied and the principle of probability inference was applied. The background of introduction of deductive Inference and its test method was mentioned, and historic arguments on the compatibility of deductive statistical inference was summarized and analyzed. Philosophical arguments on the deductive confirmation for engineering experiments was introduced. Premise, procedure, and control of the experiments are studied. As an example of the deductive probability inference three groups of experimental data were used in order to find successful inferences respectively.

이 연구의 본론에서 공학 교육에 적용되는 귀납법적 확증(confirmation)과 연역법적 검증(verification)을 다루고 이어서 귀납법 추리의 원리를 모형도를 통해 알아보았다. 그리고 이어서 공학교육에서 널리 쓰이는 확률론적 추론의 도입 배경과 보편적 명제에 대한 확률적 검정(test) )을 논의하였고 또한 실험에 대한 귀납법의 인정여부를 가지고 역사적으로 학계에서 끊임없이 논의 되어온 귀납법적 추론에 대한 정당성을 비교 분석하였다. 공학 교육에서 흔히 쓰이는 실험에 대한 철학적 명제를 가지고 실험에 대한 설명으로 선택된 귀납법의 승리와 반전, 그리고 확증에 대해 알아보았다. 이어서 실험에서의 전제, 절차, 및 통제에 대하여 논의 되어졌다. 마지막으로 귀납법적 추론 예제로써 Elliptical Trainer 실험 결과를 가지고 확률론적 추론이 어떻게 가능한지 보여 주었다. 그 결과 82%의 참 확률을 가지고 3개의 추론을 하였는데 이 연구에서는 보통 공학연구와 달리 추론(결론 법칙)에 대한 참 확률을 표기하여 공학에서 주로 적용하는 귀납법적 방법 자체가 확률추론임을 알린다.
