项目摘要

DESCRIPTION (provided by applicant): The 2012 National Science Education Standards published by the National Research Council call for an integrative, research-based curriculum in science that incorporates high quality laboratory activities that "help students learn to investigate, to construct scientific assertions, and to justify those assertions." Yet in their own "U.S. Lab Report", the NRC indicates that the majority of high school students participate in science laboratory experiences that are poorly developed and lack clear learning goals. Currently, lab activities are inhibited by many factors, including limited funds and resources, large class sizes, and inadequate teacher training. Moreover, high school science labs are often boring, and use the "cookbook" approach. Over the past 15 years we have developed and assessed the efficacy of substance abuse-focused modules on learning in high school biology and chemistry. Topics about drugs and alcohol are highly relevant and interesting to high school students. In our most recent study, we developed a lab activity that engages students "virtually" (www.rise.duke.edu/SEEK). The widespread use of this resource by teachers in our study led to the development of this proposal. We will develop a web-based platform ("REX") for educators and their students to engage in "virtual" laboratory experiments performed by real scientists. Our overall goals of this project are to 1) provide teachers with a rich resource that can be used to integrate inquiry-based "virtual" lab experiences into the classroom , 2) increase high school student mastery of basic biology and chemistry principles and 3) increase student interest in science and science careers (especially in areas of substance abuse). To achieve these goals, we have 4 specific aims: 1) develop REX (Real Experiments), an interactive web-based platform, to conduct lab experiments "online" that real scientists perform in areas of substance abuse, 2) design 6 pharmacology-oriented experiments focused in areas of drug and alcohol abuse to populate REX. We will incorporate an interactive algorithm that allows students to participate in the design of their own experiment, analyze data generated by real scientists, interpret results, and reflect on their findings and next steps, 3) field-test REX in10 high school science classrooms (~ 1000 students) in the Durham, NC school district, which comprises a large population of underrepresented minorities, and 4) perform several types of assessments that test the effect of REX on mastery of basic biology and chemistry principles and determine the effect of REX on interest in science and science careers (the study will be controlled). Finally we will conduct an evaluation of the usability of REX by teachers before dissemination publically. We expect that our engaging online resource will be especially useful to teachers and schools without money, training, or infrastructure to conduct laboratory experiments.

描述（由申请人提供）：国家研究委员会发布的2012年国家科学教育标准呼吁，基于研究，基于研究的科学课程，其中包含了高质量的实验室活动，这些活动“帮助学生学习调查，建立科学的主张和证明这些断言是合理的。”但自己 “美国实验室报告”，NRC指出，大多数高中生都参加了科学实验室的经验，这些经验不佳，缺乏明确的学习目标。当前，实验室活动受到许多因素的抑制，包括有限的资金和资源，大型班级规模以及教师培训不足。此外，高中科学实验室通常很无聊，并使用“食谱”方法。在过去的15年中，我们已经开发并评估了以滥用药物滥用模块在高中生物学和化学中学习的功效。关于毒品和酒精的主题对高中生高度相关且有趣。在我们的最新研究中，我们开发了一项实验室活动，该活动“实际上”（www.rise.duke.edu/seek）。教师在我们的研究中广泛使用此资源，导致了这一建议的发展。我们将开发一个基于Web的平台（“ REX”），供教育工作者及其学生进行真正的科学家进行的“虚拟”实验室实验。我们该项目的总体目标是1）为教师提供丰富的资源，可用于将基于询问的“虚拟”实验室体验整合到课堂上，2）增加高中学生对基本生物学和化学原则的掌握以及3）增加学生对科学和科学职业的兴趣（尤其是在滥用毒品的领域）。为了实现这些目标，我们有4个具体目标：1）开发基于互动网络的平台REX（实际实验），以进行实验室实验“在线”，而真正的科学家在药物滥用领域进行了“在线”，2）设计6药理学 - 面向导向的实验集中在毒品和酒精滥用领域，以填充REX。我们将合并一种互动算法，该算法使学生可以参与自己的实验设计，分析由真正的科学家生成的数据，解释结果并反思他们的发现和下一步，3）现场测试REX IN10高中北卡罗来纳州达勒姆学区的科学教室（约1000名学生）组成了大量代表性不足的少数群体，4）进行多种评估，以测试REX对掌握基本生物学和化学原则的影响并确定效果REX对科学和科学职业的兴趣（该研究将得到控制）。最后，在公开传播之前，我们将对教师对Rex的可用性进行评估。我们预计，我们引人入胜的在线资源将对没有钱，培训或基础设施进行实验室实验的教师和学校特别有用。
