论文摘要
基于查询的建模对于科学实践至关重要。但是，由于特定于领域的知识和定量技能有限，新手科学家的建模很困难。 Vera是一种交互式工具，可帮助用户构建生态现象的概念模型，将其作为模拟并检查其预测。 Vera通过提供对大规模领域知识的访问来提供认知脚手架。 Vera系统在两种不同的环境中由大学级学生测试：一般的东南R1大学的一般生态讲座课程（n = 91），以及研究实验室的受控实验（n = 15）。两项研究都表明，通过Vera使学生参与生态建模有助于他们更好地理解基本的生物学概念。后一项研究还表明，提供获取领域知识的访问有助于学生建立更复杂的模型。
Inquiry-based modeling is essential to scientific practice. However, modeling is difficult for novice scientists in part due to limited domain-specific knowledge and quantitative skills. VERA is an interactive tool that helps users construct conceptual models of ecological phenomena, run them as simulations, and examine their predictions. VERA provides cognitive scaffolding for modeling by supplying access to large-scale domain knowledge. The VERA system was tested by college-level students in two different settings: a general ecology lecture course (N=91) at a large southeastern R1 university and a controlled experiment in a research laboratory (N=15). Both studies indicated that engaging students in ecological modeling through VERA helped them better understand basic biological concepts. The latter study additionally revealed that providing access to domain knowledge helped students build more complex models.
