A 3-D Multimodal Approach to K-8 Environmental Health Literacy

项目摘要 SBIR项目将为教师开发一个基于网络的交互式数字媒体产品， K-8年级的学生。数字媒体将采取多模式内容和数字媒体的形式。 调查暴露于空气、水、食品供应和环境中的危害风险的工具， 消费品，特别是那些不成比例地影响全国2300万低， 收入和英语学习者的学生，并与他们的家庭和地理相关。的 产品将采用独特的多模式，基于语言的方法来教学环境 符合下一代科学标准（NGSS）“3-D”学习的健康素养 模型长期目标是大幅度提高环境卫生知识， 提高对接触风险的认识，并促进避免风险的行为。 第一阶段的具体目标是使用一套初步的 内容分为四个等级，为开发新的数字科学笔记本提供技术支持 NGSS实践，以测试课堂实施和潜在学习的可行性 结果，并收集商业成功的可衡量指标。初始内容集 将包括空气，水，食品和消费品危害的单位。第一阶段研究将测试 三阶段研究的可行性：（1）专家和教师评审，（2）可用性实验室测试，（3） 课堂试点测试与班级跨越四个年级超过8周的时间在一个不同的 采用NGSS州的K-8内城学校。调查人员将使用直接 观察，原型收集的使用数据，以及与教师的结构化访谈， 专家回答了关键的研究问题。II期将包括一项RCT疗效研究。 新产品将采用融合四种语言领域的新颖教学方法 （听、说、阅读和写）与基于探究的、与NGSS一致的调查 与目标危害相关的科学现象，如接触铅、霉菌、食物 污染物或纳米颗粒。来自国家科学基金会赞助的初步数据 研究表明，这种方法可以非常有效，使学习新知识的速度提高两倍。 小学生的科学概念。这将是有史以来第一个应用新的 方法和支持技术的环境健康素养。拟议产品具有 强大的商业潜力，因为它将与更广泛的 产品线，是针对该公司的领先K-12学区客户的基础。 ! 1

Project Summary The SBIR project will develop a web-based interactive digital media product for teachers and students in grades K-8. The digital media will take the form of multimodal content and digital tools that investigate the risks of exposure to hazards in the air, water, food supply, and in consumer products—especially those that disproportionately affect the nation's 23 million low- income and English Learner students and are relevant to their homes and geographies. The product will employ a unique multimodal, language-based approach to teaching environmental health literacy that aligns with the Next Generation Science Standards (NGSS) "3-D" learning model. The long-term objectives will be to dramatically improve environmental health literacy, increase awareness of exposure risks, and to promote risk-avoidance behaviors. The specific aims for Phase I will be to demonstrate technical feasibility using an initial set of content at four grade levels, to develop a new digital science notebook technology to support the NGSS practices, to test the feasibility of classroom implementation and potential learning outcomes, and to collect measurable indicators of commercial success. The initial set of content will include units on air, water, food, and consumer product hazards. Phase I research will test feasibility in a three-stage study: (1) expert and teacher review, (2) usability lab testing, and (3) classroom pilot testing with classes across four grade levels over an 8-week period at a diverse K-8 inner city school in an NGSS adoption state. Investigators will use a combination of direct observation, usage data collected by the prototype, and structured interviews with teachers and experts to answer the key research questions. Phase II will include an RCT efficacy study. The new product will use a novel teaching method that integrates the four language domains (listening, speaking, reading and writing) with inquiry-based, NGSS-aligned investigation of scientific phenomena relevant to the targeted hazards, such as exposure to lead, mold, food contaminants, or nanoparticles. Preliminary data from National Science Foundation-sponsored research indicate that this approach can be highly effective, tripling the rate of learning new science concepts among elementary students. This will be the first project to ever apply the new method and supporting technologies to environmental health literacy. The proposed product has strong commercial potential because it will be integrated and interoperable with a broader product line that is targeted to the company's base of leading K-12 school district customers. !1
