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.

Concord联盟正在使用以颜色为颜色的传感器探索K-2学生对两个马萨诸塞州学区的热量和温度的理解。该项目正在调查以下研究问题： - 可视化，与日常经验相关的数据收集以及将学生反思链接到创意探索中的学生反思，并促进K-2学生对温度和热量的理解？ - 如何使用重播视频和反思有助于解决K-2学生的先入之见并提高学生对热量和温度的理解吗？ - 通过数字传感技术收集可视化和数据的使用可以推动K-2学生超越K-2 Science框架的目标吗？该项目正在10个教室中实施，约250名代表不同人群的儿童。正在创建探索活动，并且正在录像进行活动。学生对每项活动进行简短的评估。项目人员将与学生重新访问视频，以更深入地探索学生的概念。教育设计公司的大卫·里德（David Reider）正在进行评估，该评估将重点介绍1）程序功效和设计以及2）与研究设计保持一致。它在设计中具有年度总结报告。从他们的数据中，该项目正在构建学生的热量和温度理论的进行性层次结构。该项目还制定了一项协议，教师可以用来与支持儿童重建其最初概念的儿童进行更好的对话。探索活动，评估和项目数据可通过Concord Consortium的网站通过开源提供，并向多个专业受众提供。
