量詞是華語重要的特色之一，所有的名詞與數量詞及指示詞出現時必須伴隨量詞。量詞的選擇依名詞的不同而改變，每個名詞有其約定成俗的量詞，有的名詞有一個以上的量詞可接，這對學習以華語爲第二語的學習者爲一大挑戰。本研究根據形狀認知基礎開發量詞數位學習互動教學軟體，包括條、根、枝、張、面、片、個、顆、粒。經30名學習華語的學生進行十週的教學實驗，結果發現母語沒有量詞的學生進步，而母語有量詞的反而退步。

Classifiers are important characteristics of Chinese. All the noun phrases with numerals or demonstratives must co-occur with classifiers, for example, liang zhang zhuozi 'two CL table' or zhe zhi bi 'this CL pen.' Classifiers vary depending on the nouns. This poses a big challenge for learners of Chinese as second language. The goal of this study is to develop a multimedia classifier learning program based on shape.Thirty CSL learners participated in our study: fifteen in the experimental group and fifteen in the control group. The experimental group used the multimedia program and the control group received the same information as paper assignments introducing the nine shape classifiers including saliently one-dimensional tiao, gen, zhi, saliently two-dimensional zhang, pian, mian, and saliently three-dimensional ge, ke, and li. The semantic bases of classifiers were introduced inductively followed by drills and simulated situation.A pretest and a post test were given before and after the ten-week treatment. There is no significant difference between the two groups in the pretest. The paired-sample t-test within neither experimental and control group indicated significant progress. After analyzing by learners' L1, we found interestingly learners with classifier LI relapsed while learners with nonclassifier L1 improved after using the material.
