The Next Generation Science Standards (NGSS) identify an ambitious progression for learning energy, beginning in elementary school. To help the nation's teachers address this challenge, this project will develop and investigate the opportunities and limitations of Focus on Energy, a professional development (PD) system for elementary teachers (grades 3-5). The PD will contain: resources that will help teachers to interpret, evaluate and cultivate students' ideas about energy; classroom activities to help them to identify, track and represent energy forms and flows; and supports to help them in engaging students in these activities. Teachers will receive the science and pedagogical content knowledge they need to teach about energy in a crosscutting way across all their science curricula; students will be intellectually engaged in the practice of developing, testing, and revising a model of energy they can use to describe phenomena both in school and in their everyday lives; and formative assessment will guide the moment-by-moment advancement of students' ideas about energy.This project will develop and test a scalable model of PD that will enhance the ability of in-service early elementary teachers to help students learn energy concepts by coordinating formative assessment, face-to-face and web-based PD activities. Researchers will develop and iteratively refine tools to assess both teacher and student energy reasoning strategies. The goals of the project include (1) teachers' increased facility with, and disciplined application of, representations and energy reasoning to make sense of everyday phenomena in terms of energy; (2) teachers' increased ability to interpret student representations and ideas about energy to make instructional decisions; and (3) students' improved use of representations and energy reasoning to develop and refine models that describe energy forms and flows associated with everyday phenomena. The web-based product will contain: a set of formative assessments to help teachers to interpret student ideas about energy based on the Facets model; a series of classroom tested activities to introduce the Energy Tracking Lens (method to explore energy concept using multiple representations); and videos of classroom exemplars as well as scientists thinking out loud while using the Energy Tracking Lens. The project will refine the existing PD and build a system that supports online implementation by constructing a facilitator's guide so that the online community can run with one facilitator.

下一代科学标准 (NGSS) 确定了从小学开始的学习能量的雄心勃勃的进步。为了帮助全国教师应对这一挑战，该项目将开发并研究“聚焦能源”的机遇和局限性，这是一个针对小学教师（3-5 年级）的专业发展 (PD) 系统。 该效绩数据将包含： 帮助教师解释、评估和培养学生关于能源的想法的资源；课堂活动帮助他们识别、跟踪和表示能量形式和流动；并提供支持，帮助他们让学生参与这些活动。 教师将获得他们所需的科学和教学内容知识，以便在所有科学课程中以交叉方式教授能源知识；学生将在智力上参与开发、测试和修改能量模型的实践，他们可以用它来描述学校和日常生活中的现象；形成性评估将指导学生关于能源观念的不断进步。该项目将开发和测试可扩展的 PD 模型，该模型将增强在职早期小学教师通过协调学生学习能源概念的能力。形成性评估、面对面和基于网络的 PD 活动。 研究人员将开发并迭代完善工具来评估教师和学生的能量推理策略。该项目的目标包括（1）教师提高表征和能量推理的能力并严格应用，以理解能量方面的日常现象； (2) 教师解释学生关于能量的陈述和想法以做出教学决策的能力得到提高； (3) 学生更好地利用表征和能量推理来开发和完善描述与日常现象相关的能量形式和流动的模型。 基于网络的产品将包含： 一套形成性评估，帮助教师基于 Facets 模型解释学生关于能源的想法；一系列课堂测试活动，介绍能量跟踪镜头（使用多种表示形式探索能量概念的方法）；以及课堂范例以及科学家在使用能量跟踪镜头时大声思考的视频。该项目将完善现有的PD，通过构建促进者指南，构建支持在线实施的系统，使在线社区可以由一个促进者运行。
