隨著數位科技的快速發展以及全球華語熱，外籍人士利用數位平臺來學習華語的人數越來越多，但目前數位成人華語教材的優劣並無評定的標準，故本研究旨在透過德懷術專家問卷調查來建構出數位成人華語教材評估指標，提供發展數位成人華語教材一套衡量標準。首先，在內容上，本研究藉由文獻探討，初步架構出評估指標的雛形。為了提升本研究的信、效度和實用性，本研究於第一階段敬邀了10位在華語教學、成人第二語言教育、資訊教育等領域的專家，實施了三次德懷術專家問卷調查，建構了「數位成人華語教材評估指標」，其中包含4大向度、9個規準和60項評估指標，各項指標皆達「重要」到「非常重要」的程度。依此發展了「數位成人華語教材指標評估表」，做為未來評估數位成人華語教材的指標。

With the development of technology and the formation of global village, a trend has become obvious that adults adopt the digital Chinese learning materials as the way of acquiring Chinese. Various digital Chinese learning materials can be easily found through internet search engines. However, methods to evaluate the quality of those materials never exist. The purpose of this research is to construct the indicators of digital Chinese learning materials for adults. The first step of this research is to generalize the rules from the literature review and then to structure the standards of digital Chinese learning materials. Three times of Delphi and AHP system are adopted to construct the indicators and to convert these indicators to numerical values that can be processed and compared over the entire range of these elements. A priority is derived for each element of the hierarchy. Based on the related literature and the method of Delphi, four main indicators, nine sub-indicators and sixty items have been generalized, and then will be made use of evaluating quality of websites regarding the digital Chinese learning for adult learners.
