Concord Consortium is exploring K-2 students' understanding of heat and temperature in two Massachusetts school districts using sensors that display temperatures as colors. The project is investigating the following research questions:- How can visualizations, data collection linked to everyday experiences, and student reflection integrated into creative exploration address student preconceptions and promote K-2 student understanding of temperature and heat?- How can the use of replay of video and reflection aid in addressing K-2 student preconceptions and improve student understanding of heat and temperature?- Can the use of visualizations and data collection via digital sensing technology advance K-2 students past the goals of the K-2 science frameworks?The project is being implemented in 10 classrooms for about 250 children representing diverse populations. Exploration activities are being created, and students are being videotaped carrying out the activities. Students complete a short assessment for each activity. Project staff will revisit the videos with the students to explore student concepts at a deeper level. David Reider of Education Design Inc. is conducting the evaluation which will focus on 1) program efficacy and design and 2) alignment with research design. It is formative in design with annual summative reports. From their data, the project is constructing a progressive hierarchy of student theories of heat and temperature. The project is also producing a protocol that teachers can use to have better dialogues with children that support children's reconstruction of their initial conceptions. The exploration activities, assessments, and project data are available via open source through a website at Concord Consortium and are being presented to multiple professional audiences.

康科德财团正在探索K-2学生的理解热量和温度在两个马萨诸塞州学区使用传感器，显示温度作为颜色。该项目正在调查以下研究问题：-如何将可视化、与日常经验相关的数据收集以及学生反思融入创造性探索中，解决学生的先入为主的观念并促进K-2学生对温度和热量的理解？- 如何使用视频回放和反思来帮助解决K-2学生的先入之见，并提高学生对热量和温度的理解？ 通过数字传感技术使用可视化和数据收集是否能使K-2学生超越K-2科学框架的目标？该项目正在10个教室为代表不同人口的约250名儿童实施。正在开展探索活动，并对学生开展活动进行录像。学生完成每个活动的简短评估。项目工作人员将与学生一起重温视频，以更深层次地探索学生的概念。教育设计公司的大卫雷德。正在进行评估，重点是1）计划的有效性和设计，2）与研究设计的一致性。它是形成性的设计与年度总结性报告。根据他们的数据，该项目正在构建一个渐进的学生热和温度理论层次。该项目还制定了一项协议，教师可以使用该协议与儿童进行更好的对话，支持儿童重建其最初的概念。勘探活动，评估和项目数据可通过Concord Consortium网站的开源提供，并向多个专业受众展示。
