Empirical Research, STEM Teaching and Learning in Formal and Informal Settings: Strengthening Measurement Curriculum, Teaching, & Research

该项目建立在瑞斯先前的一个项目--加强明天的测量教育(STEM)--的资源和成果的基础上，该项目对三门小学数学课程中空间测量内容(长度、面积和体积)的特点和局限性进行了精细的分析。它将扩展、深化和报告STEM的结果，包括长度、面积和数量，但也将通过改进教育实践集中解决将这些知识应用于工作的任务。该项目将完成小学年级对长度、面积和体积的分析，并与三门基础课程的作者一起探索如何加强现有材料。它将分析备受推崇的新加坡数学课程，并将调查结果与美国的结果进行比较。它还将处理与基础科学课程中的测量主题相关的问题。它将开发和测试有效的方法，以丰富职前小学教师对核心测量原则的知识，并与实践教师合作，利用创新活动和现有课程内容来改进他们的测量课程。最后，它将实施一个为期三年的测量迷你中心，该中心将汇集美国主要研究和开发学者和项目，以实现持续的互动、创新和合作。三年项目致力于寻找在小学数学课程中加强测量教学和学习的方法。国家和国际评估显示，美国儿童在这一内容领域一直表现不佳。困难可以追溯到概念和程序理解方面的重大缺陷，包括解决应用问题。该项目将把新加坡小学课程中使用的测量方法与美国现行的小学教科书进行比较。此外，在科学和数学领域从事测量领域工作的研究人员和从业人员将参加一年一度的微型中心，目的是分享与测量教学和学习有关的结果和最佳做法。研究的另一个有趣的方面是将研究结果纳入到职前小学教师的测量课程中，包括为实习教师提供的相关测量经验。从长远来看，该项目有望提供一种课程模式，有可能在全国范围内复制。

The project builds on the resources and results of a prior REESE project, Strengthening Tomorrow's Education in Measurement (STEM), that has produced a fine-grained analysis of the character and limitations of the spatial measurement content (length, area, and volume) in three elementary mathematics curricula. It will expand, deepen, and report STEM results for length, area, and volume but will also centrally address the task of putting that knowledge to work by improving educational practice. The project will complete the primary grades analysis of length, area, and volume and explore with the authors of the three elementary curricula ways to strengthen their existing materials. It will analyze the highly-regarded Singapore mathematics curriculum and compare and contrast findings with the U.S. results. It will also address issues relevant to the topic of measurement in the elementary science curriculum. It will develop and test effective ways of enriching preservice elementary teachers' knowledge of core measurement principles and work with practicing teachers to improve their measurement lessons using both innovative activities and existing curricular content. Finally, it will implement a three-year measurement mini-Center that will bring together major U.S. research and development scholars and projects for sustained interaction, innovation, and collaboration.The three-year project is concerned with finding ways to strengthen instruction and learning of measurement in the elementary school mathematics curriculum. State and international assessments show U.S. children to be consistently underperforming in this content area. Difficulties are traced to significant weaknesses in conceptual and procedural understanding, including word problem solving. The project will compare the measurement approach used in the Singapore elementary curriculum with current U.S. elementary textbooks. Also, researchers and practitioners who work in the area of measurement in both science and mathematics contexts will participate in a yearly mini-Center with the goal of sharing findings and best practices relevant to the teaching and learning of measurement. Another interesting aspect of the study is the incorporation of findings in measurement courses for preservice elementary teachers, including relevant measurement experiences for practicing teachers. In the long term, the project is expected to provide a curriculum model that can potentially be replicated across the country.
