计算机交互式评价的开发研究——以科学探究为例

Development of computer-based interactive assessment:the case of science inquiry

计算机交互式评价以计算机模拟的形式呈现学科知识及其系统结构,并支持新颖的交互形式。评价学生的科学探究能力不仅需要创设丰富的任务情境,同时也要收集和分析学生的行为和作答数据。鉴于交互式评价与科学探究评价的契合性,文章基于以证据为中心(Evidence-Centered Design,ECD)的评价设计理念,解析了交互式科学探究评价的设计流程。首先,介绍了评价设计的理论基础--ECD框架。其次,结合科学探究评价的典型研究项目,以评价设计流程的任务分析、任务创设和数据分析为主线,总结了任务分析的领域信息来源、任务情境标准、任务创设的界面形式、学生作品和系统响应,以及数据分析中使用的多种数学模型。最后,讨论了交互式评价在评价的标准、实用性、非认知因素以及协同开发等方面应关注的问题和未来的发展方向,旨在丰富我国有关交互式评价开发的理论和实践研究。

Computer-based interactive assessment presents subject knowledge and its organization structure in the form of computer simulation,enabling innovative forms of interaction.The assessment of student science inquiry competency involves not only designing task-based scenarios but also collecting and analyzing data concerning student behavior and task completion.It is argued that computer-based interactive assessment is a tool fit for this purpose.After introducing the ECD approach,the study uses a science inquiry project as a case study to deconstruct the process of interactive assessment for science inquiry competency in terms of learning objectives(tasks to be completed),task design and data analysis.It also discusses assessment criteria,functionality,non-cognitive factors and co-development as well as directions for future research.
