EXP: Learning Lens: An Evidence-Centered Tool for 21st Century Assessment

在这个网络学习：转变教育经验项目中，一个由评估专家、学习科学家、K12教育工作者、教育技术专家和非正式科学教育工作者组成的协作团队正在探索一个名为学习镜头的工具的设计和可行性，这是一个移动多媒体工具，用于在学习活动中收集数据，可以揭示学习者的能力和理解以及学习者与教育工作者之间的互动。该系统的设计借鉴了循证评估的思想，旨在允许用户收集可以用来支持关于学习者理解和能力的争论的各种数据，包括学习者的正式产品、他们的演示或解释、同龄人之间的讨论以及与学习环境中的人和物的互动。这样的工具可以在教育从业者的教育中发挥重要作用。职前和在职教师可能会偶尔在教室里收集数据，用于与其他人讨论他们的实践。或者，那些在实践中观察教育工作者的人可能会收集数据，供以后反思教育实践时使用。此外，这样的工具有望加强评估。虽然纸笔测试可以用来评估理解能力和一些纪律技能，但要客观地评估复杂的社交、沟通、推理和元认知技能则更具挑战性。正在开发学习镜片，以促进对这种技能的循证分析。有了这个工具，研究人员、教师观察员或教师自己将收集数据，显示学习者理解或能做什么。这样的数据采集有望使教育工作者和研究人员能够以迭代和协作的方式记录学习者的发展，开发评估规则，跟踪学生在现场的实时成长，并确定教学行动和策略的结果。

In this Cyberlearning: Transforming Education EXP project, a collaborative team of assessment specialists, learning scientists, K12 educators, educational technologisst, and informal science educators are exploring the design and feasibility of a tool called the Learning Lens, a mobile multi-media tool for gathering data in the midst of learning activities that can shed light on learners' capabilities and understanding and the interactions between learners and educators. The system's design is informed by ideas of evidence-based assessment; it is designed to allow a user to collect the kinds of data that can be used to support arguments about what learners understand and are capable of, including formal products of learners, their presentations or explanations, discussions among peers, and interactions with people and objects in the learning environment.Such a tool could play important roles in the the education of education practitioners. Pre-service and in-service teachers might gather data sporadically in their classrooms to use in discussions with others about their practice. Or, those observing educators in practice might gather data to be used later in reflecting on educational practices. As well, such a tool holds promise for enhancing assessment. While paper-and-pencil testing can be used to assess understanding and some disciplinary skills, it is quite a bit more challenging to objectively assess complex social, communication, reasoning, and meta-cognitive skills. The Learning Lens is being developed to promote evidence-based analysis of such skills. With the tool, researchers or teacher observers or teachers themselves would collect data showing what learners understand or can do. Such data capture holds promise for allowing educators and researchers to iteratively and collaboratively document learner development, develop assessment rubrics, track students' real-time growth in situ, and identify outcomes of pedagogical moves and tactics.
