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

项目摘要 SBIR项目将为教师和教师开发基于网络的互动数字媒体产品 K-8年级的学生。数字媒体将采取多模式内容和数字形式 调查暴露在空气、水、食物供应和环境中的危险的风险的工具 消费品-特别是那些对全国2300万人的低收入产生不成比例影响的产品- 收入和英语学习者，并与他们的家庭和地理位置相关。这个 产品将采用独特的多模式、基于语言的方法来教授环境 符合下一代科学标准(NGSS)的健康素养“3-D”学习 模特。长期目标将是大幅提高环境健康素养， 提高暴露风险意识，促进风险规避行为。 第一阶段的具体目标将是使用一套初始的 内容分四个档次，为开发新的数字科学笔记本技术提供支持 NGSS实践，以检验课堂实施的可行性和潜在的学习 结果，并收集商业成功的可衡量指标。最初的一组内容 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，以及(3) 在为期8周的时间里，对四个年级的班级进行课堂试点测试 处于NGSS收养状态的K-8市中心学校。调查人员将结合使用直接 观察，原型收集的使用数据，以及对教师和 专家回答关键研究问题。第二阶段将包括一项随机对照试验疗效研究。 新产品将使用一种新的教学方法，将四个语言领域整合在一起 (听、说、读、写)通过基于调查的、与NGSS一致的调查 与目标危害有关的科学现象，如接触铅、霉菌、食物 污染物或纳米颗粒。国家科学基金资助的初步数据 研究表明，这种方法非常有效，可以使学习新知识的速度提高三倍 在小学生中培养科学概念。这将是第一个应用新技术的项目 环境健康素养的方法和支持技术。建议的产品具有 强大的商业潜力，因为它将与更广泛的 针对公司领先的K-12学区客户群的产品线。 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
