現代電腦與通訊技術解除了溝通上的時空限制，加上新興網路與多媒體科技更促成了線上學習環境的實現與多元化蓬勃發展，人們藉由網上課程訓練，可隨時、隨地、隨意（視其所需）地習取新知。目前台灣國內少有針對電腦輔助日語文法教材，作線上測驗題組建構之研究。本研究針對日語能力測驗2級（N2）助動詞和助詞等的試題模組，分析試題難度與答對率。本研究的試題模組結論有以下3點。（1）對受測者而言，答對率較高的試題題組為格助詞「に」、雙重否定「～かねない」等試題。（2）對受測者而言，答對率較低的試題題組為形式名詞「もの」、否定「～でならなくなる」等試題。（2）對高得分的受測者而言，全部答對的試題題組為否定「ありえない」、副詞「必ずしも」、格助詞「を」、疑問詞「だれ」等試題。

The rise of internet and multimedia technology has facilitated the creation of an online learning environment that is vigorously developing and diversifying. People can now use the internet to attend classes and receive training, as well as acquire new information anytime, anywhere, and however they like (dependent on individual needs). However, there is currently research in Taiwan that focuses on using a web-based tests (WBT) for Japanese grammar instruction. This research focuses on the auxiliary verb and particle test questions found in Levels 2 (N2) of the Japanese Language Proficiency Test, utilizing SAS to analyze question's difficulty and examinee's ability. The analysisof these question types led to the following three conclusions: (1) Double negative (kanenai), case particle(ni) have high answer rate for the subjects. (2) Negative (denaranakunaru), noun(mono) have low answer rate for the subjects. (3) Negative (arienai),adverbial(kanarazusimo), case particle(wo), Interro - gative(dare) have full answer rate for the hight-scores.
