一、由各面向的整體性總評分值可看出，專家在訊息設計原則的重要性排序上無顯著差異。 二、根據專家意見，歸納出數位教材之「一般性」訊息設計原則共計18項，「事實」學習結果之訊息設計原則計有25項，及「概念」學習結果之訊息設計原則計有37項，共計有80項原則。研究結果並依照各原則之重要性排序列出，編製表格，供數位教學設計者參考。 三、研究發現在「事實」和「概念」訊息設計原則上有六項相同之原則，應可推論至其他種類學習結果之訊息設計原則，亦建議教學設計者可把握此相同性。 The purpose of this study was to construct the message design principles for e-materials in teaching facts and concepts. Literature analysis method was first used in order to synthesize and develop related preliminary questionnaire before the formal survey. Then, the Fuzzy Delphi Method was implemented to collect opinions from 15 experts. Based on the experts’average opinions, this results were to present the principles for designing E-materials in teaching facts and concepts and also worked as references for instructional designers. The outcomes were summaried as follow： 1.There were no significant difference among experts’opinions in those principles. 2.Based on the results from fuzzy Delphi technique, there were 18 items of e-martial teaching of general message design rules, 25 items of message design rules of E-martial teaching of Facts learning outcome, and 37 items of message design rules of E-martial teaching of Concepts learning outcome to be generated . Totally, there were 80 items of message design principles in teaching facts and concepts. Those items of principles were listed by their importance order. 3.Overall,it was found that the Facts and Concepts categories shared the 6 same items of principles. This result suggested those 6 items may be used as design principles for other learning domain. This study is important because the result provides a guide or scaffolding for instructional designers to design an effective message in teaching facts and concept.
