This research project will investigate the effects social organization, learning technologies, and their interrelationships, have on the geometric reasoning of PreK-3 students. Social organization is operationalized here as the strategic grouping of students into triads to engage in collaborative problem solving. Learning technologies are operationalized here as physical and virtual manipulative types (tangrams, pentominoes, geoboards) together with supporting software designed to facilitate students in accessing their mathematical knowledge. Based on findings from preliminary work in this area, it is proposed that learning technologies allow for fluid exchanges between peers, and transitions between physical and virtual manipulatives, significantly enhancing geometric reasoning. The current project presents a robust research and design framework that combines iterative cycles of field studies in the classroom with development and experimentation in the lab. The goal is to design, develop and prototype a tabletop computer interface that allows for unprecedented exchanges among student peers and transitions between manipulative types. The tabletop interface will serve first as the apparatus that facilitates experimental manipulations, later being used, through iterative refinement, as the learning technology platform by which students gain access to mathematical knowledge. The advancement proposed by the current work is that it places all interaction on the horizontal tabletop. This is critical in that it removes confounding effects of different seating and screen orientations from pilot study findings. Manipulations of geometric artifacts reside along two dimensions of research questions: the effects of social interaction and of learning technology on geometric reasoning. Hence, the proposed studies will allow investigation of different transitions between fully functional and fully operational thinking, functional and qualitative operational thinking, and qualitative and quantitative parametric thinking with the same interaction morphologies.The proposed research has the potential to make significant contributions to the following intellectual domains: 1) child development -understanding children's development of mathematical reasoning in terms of learning trajectories 2) mathematics education - understanding teachers' use of advanced learning technologies and role in classroom instruction, and children's learning of mathematics using advanced learning technologies; 3) learning sciences - refining techniques for the analysis, design, and development of advanced learning technologies in use; 4) human-computer interaction -design of interfaces that aid learning to include gestural interaction, tangible manipulation, and horizontal displays; and 5) psycholinguistics - grounding of concepts developed in other domains in the classroom environment. Results from the research will also have much to say about the participation of girls in the mathematics classroom, a goal being to encourage rich discourse of all students. In addition, developed technologies may have implications for the education of special needs children as instructional interfaces can be modified and reconfigured to meet the diverse needs of this underrepresented group. A significant outcome of collaboration among these disciplines will be cutting-edge research opportunities for doctoral students and groundwork for the establishment of new curricula and, possibly, degree programs.

这个研究项目将调查社会组织，学习技术，以及它们之间的相互关系，对PreK-3学生的几何推理的影响。社会组织在这里是可操作的，作为学生的战略分组到黑社会参与合作解决问题。学习技术在这里作为物理和虚拟操作类型（七巧板，五角棋，geoboards）以及旨在帮助学生获取数学知识的支持软件进行操作。基于在这一领域的初步工作的结果，建议学习技术允许同行之间的流体交换，物理和虚拟操纵之间的过渡，显着增强几何推理。目前的项目提出了一个强大的研究和设计框架，结合了课堂上的实地研究与实验室中的开发和实验的迭代周期。我们的目标是设计，开发和原型桌面计算机界面，允许学生之间前所未有的交流和操纵类型之间的转换。桌面界面将首先作为促进实验操作的装置，随后通过迭代改进，作为学生获得数学知识的学习技术平台。目前的工作提出的进步是，它把所有的互动在水平的桌面上。这是至关重要的，因为它从试点研究结果中消除了不同座位和屏幕方向的混淆影响。几何人工制品的操作存在于沿着两个维度的研究问题：社会互动和学习技术对几何推理的影响。因此，拟议的研究将允许调查完全功能和完全操作思维，功能和定性操作思维，以及定性和定量参数思维之间的不同过渡，具有相同的相互作用形态。拟议的研究有可能在以下知识领域做出重大贡献：1）儿童发展-从学习轨迹的角度理解儿童数学推理的发展2）数学教育-理解教师对先进学习技术的使用和在课堂教学中的作用，3）学习科学--改进分析、设计和开发使用中的高级学习技术的技术; 4）人机交互--设计有助于学习的界面，包括手势交互、有形操作和水平显示; 5）心理语言学-在课堂环境中将其他领域中发展的概念作为基础。研究结果也将对女孩参与数学课堂有很大影响，其目标是鼓励所有学生进行丰富的讨论。此外，发达的技术可能对特殊需要儿童的教育产生影响，因为可以修改和重新配置教学界面，以满足这一代表性不足的群体的各种需求。这些学科之间合作的一个重要成果将是为博士生提供前沿研究机会，并为建立新的课程和学位课程奠定基础。
