本文通过调查TEM4语法词汇项目的潜在结构和影响构念的因素来评价该项目的构念效度。采用专家判断法收集内容效度的证据,Rasch模型分析题目作答反应对构念效度的影响,并借助验证性因子分析了解项目的构念构成。研究结果显示,内容考点判断非常一致;绝大部份题目拟合模型,项目有较好的单维性特征,题目作答基本上相互独立,不过,项目相对于考生的能力来说比较难,从而导致少数难度较大的题目不拟合模型,对项目的构念贡献不足;语法和词汇属于两个非常相关但是又相互独立的构念。
本文通過調查TEM4語法詞彙項目的潛在結構和影響構唸的因素來評價該項目的構唸效度。採用專傢判斷法收集內容效度的證據,Rasch模型分析題目作答反應對構唸效度的影響,併藉助驗證性因子分析瞭解項目的構唸構成。研究結果顯示,內容攷點判斷非常一緻;絕大部份題目擬閤模型,項目有較好的單維性特徵,題目作答基本上相互獨立,不過,項目相對于攷生的能力來說比較難,從而導緻少數難度較大的題目不擬閤模型,對項目的構唸貢獻不足;語法和詞彙屬于兩箇非常相關但是又相互獨立的構唸。

The study evaluates the construct validity of the Grammar and Vocabulary Section of TEM4 by investigating the underpinning structure of the test, possible construct under-representation and construct-irrelevant threats. To this end, content-related evidence was gathered by expert judgment; construct representation and relevance were explored by Rasch anal- ysis and confirmatory factor analysis. The findings revealed that independent judgments yield consistent results on content-related evidence;construct-irrelevance is absent thanks to the adherence of data to unidimensionality, reasonably local independence, and good measurement properties of most items, but the subtest is relatively difficulty for the sample, which might attribute to some erratic item responses and construct under-representation; grammar knowledge and vocabulary knowledge are two highly correlated traits and few item responses are likely to be depend- ent due to some correlated error terms.
