Aug 29, 2026

Duolingo English Test (DET) 研究报告围绕“写作能力构念”建立概念化框架，并说明该框架如何服务于以数字优先为导向的语言评测全过程。文中在 Burstein 等提出的理论生态系统下，结合语言学习理论、评测设计与测量/心理计量学，为写作能力的评估提供理论支撑。报告进一步阐述写作任务的设计原则、项目示例，以及动态任务类型与 AI 生成、实时适应在计算机化测试中的应用，以提升测量可靠性与构念覆盖。

Duolingo English Test—Writing Construct Duolingo Research Report DRR-22-03 Original Version: March 28, 2022 (15 pages) Current Version: June 23, 2025 (10 pages) [https://englishtest.duolingo.com/research](https://englishtest.duolingo.com/research) Sarah Goodwin∗ , Yigal Attali∗ , Geoffrey T. LaFlair∗ , Yena Park∗ , Andrew Runge∗ , Alina A. von Davier∗ , Kevin P. Yancey∗ , Ben Naismith∗ , Ping-Lin Chuang∗ Abstract Assessments, especially those used for high-stakes decision making, draw on evidence-based frameworks. Such frameworks inform every aspect of the testing process, from development to results reporting. The frameworks that language assessment professionals use draw on theory in language learning, assessment design, and measurement and psychometrics in order to provide underpinnings for the evaluation of language skills including speaking, writing, reading, and listening. This paper focuses on the construct, or underlying trait, of writing ability. The paper conceptualizes the writing construct for the Duolingo English Test (DET) . This work is situated in the Burstein et al. (2022) theoretical ecosystem for digital-first assessment, the first representation of its kind that incorporates design, validation/measurement, and security all situated directly in assessment practices that are digital first. The paper first provides background information about the DET and then defines the writing construct, includingthe purposes for writing. It also introduces principles underpinning the design of writing items and illustrates sample items that assess the writing construct. Furthermore, it details the DET’s integration of dynamic task types and the application of artificial intelligence (AI) in item generation and real-time adaptation, presenting a distinctive approach to evaluating the writing construct in a computer-based testing environment.
