Abstract

In this study, we conceptualize two approaches, model-based and text-based, grounded on mental models and discourse comprehension theories, to computerized summary analysis. We juxtapose the model-based approach with the text-based approach to explore shared knowledge dimensions and associated measures from both approaches and use them to examine changes in students' summaries over time. We used 108 cases in which we computed model-based and text-based measures for two versions of students' summaries (i.e., initial and final revisions), resulting in a total of 216 observations. We used correlations, Principal Components Analysis (PCA), and Linear Mixed-Effects models. This exploratory investigation suggested a shortlist of text-based measures, and the findings of the PCA demonstrated that both model-based and text-based measures explained the three-dimensional model (i.e., surface, structure, and semantic). Overall, model-based measures were better for tracking changes in the surface dimension, while text-based measures were descriptive of the structure dimension. Both approaches worked well for the semantic dimension. The tested text-based measures can serve as a cross-reference to evaluate students' summaries along with the model-based measures. The current study shows the potential of using multidimensional measures to provide formative feedback on students' knowledge structure and writing styles along the three dimensions.

探索多维人类思维:基于模型和基于文本的方法
在本研究中,我们以心智模型和话语理解理论为基础,将基于模型和基于文本的两种方法概念化,用于计算机化摘要分析。我们将基于模型的方法与基于文本的方法并列,以探索这两种方法的共享知识维度和相关测量方法,并用它们来研究学生摘要随时间的变化。我们使用了 108 个案例,对两个版本的学生总结(即初始和最终修订版)计算了基于模型和基于文本的测量值,共得出 216 个观测值。我们使用了相关分析、主成分分析(PCA)和线性混合效应模型。这项探索性调查提出了一份基于文本的衡量标准短名单,PCA 的结果表明,基于模型的衡量标准和基于文本的衡量标准都能解释三维模型(即表面、结构和语义)。总体而言,基于模型的测量方法更适合跟踪表面维度的变化,而基于文本的测量方法则能描述结构维度的变化。这两种方法在语义维度上都有很好的效果。经过测试的基于文本的测量方法可以作为交叉参考,与基于模型的测量方法一起评估学生的摘要。目前的研究表明,使用多维度测量方法可以对学生在三个维度上的知识结构和写作风格提供形成性反馈。

期刊介绍: Assessing Writing is a refereed international journal providing a forum for ideas, research and practice on the assessment of written language. Assessing Writing publishes articles, book reviews, conference reports, and academic exchanges concerning writing assessments of all kinds, including traditional (direct and standardised forms of) testing of writing, alternative performance assessments (such as portfolios), workplace sampling and classroom assessment. The journal focuses on all stages of the writing assessment process, including needs evaluation, assessment creation, implementation, and validation, and test development.
