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(由申请者提供)：由国家研究委员会发布的2012年国家科学教育标准呼吁建立一个综合的、以研究为基础的科学课程，其中包括高质量的实验室活动，帮助学生学习调查，构建科学断言，并证明这些断言是合理的。然而，在他们自己 《美国实验室报告》，NRC指出，大多数高中生参与的科学实验室体验发展较差，缺乏明确的学习目标。目前，实验室活动受到许多因素的制约，包括资金和资源有限，班级规模大，教师培训不足。此外，高中的科学实验室通常很枯燥，而且使用“食谱”的方法。在过去的15年里，我们开发并评估了以物质滥用为重点的高中生物和化学学习模块的有效性。关于毒品和酒精的话题对高中生来说非常相关和有趣。在我们最近的一项研究中，我们开发了一项实验活动，让学生“虚拟地”参与进来(www.rise.duke.edu/Seek)。在我们的研究中，教师对这一资源的广泛使用导致了这一提议的发展。我们将开发一个基于网络的平台(“REX”)，让教育工作者和他们的学生参与由真正的科学家进行的“虚拟”实验室实验。我们这个项目的总体目标是：1)为教师提供丰富的资源，可用于将基于探究的“虚拟”实验室体验融入课堂；2)提高高中生对基本生物和化学原理的掌握；3)提高学生对科学和科学职业(特别是在药物滥用领域)的兴趣。为了实现这些目标，我们有4个具体目标：1)开发REX(真实实验)，一个基于网络的互动平台，进行真正的科学家在药物滥用领域进行的实验室实验；2)设计6个专注于药物和酒精滥用领域的药理学实验，以填充REX。我们将加入一种交互式算法，允许学生参与他们自己的实验设计，分析真正的科学家产生的数据，解释结果，并反思他们的发现和下一步行动，3)在10所高中进行现场测试REX 在北卡罗来纳州达勒姆(Durham，NC)学区的科学教室(约1000名学生)，其中包括大量未被充分代表的少数族裔，4)进行几种类型的评估，以测试REX对掌握基本生物学和化学原理的影响，并确定REX对科学兴趣和科学职业的影响(研究将受到控制)。最后，在公开传播之前，我们将由教师对REX的可用性进行评估。我们预计，我们吸引人的在线资源将对没有资金、培训或基础设施来进行实验室实验的教师和学校特别有用。
