This SBIR Phase II project will develop software that teaches 4th-10th grade students how to solve mathematical problems that seem difficult, maybe even hopeless at first. Problems, by definition, are hard to solve. They require intensive thinking and open-ended experimentation, which are often not possible in today's classrooms. In the software, an expert avatar takes students on math explorations in video-game-quality 3D where they visualize and discover eye-opening mathematical truths. The program helps teachers turn math into exciting explorations that students will love. For example, as students fly a jumbo jet from New York to Tokyo, they effortlessly discover methods for finding the shortest path between two points on the surface of a sphere, which is a difficult geometry problem. Teachers can easily fit the program into their daily instruction and get crucial details about the weak spots of each student. The joy of discovery is envisioned to increase students' interest in math, science, and engineering and to significantly reduce their math anxiety. Besides creating jobs and tax revenue, the project is expected to contribute to measurably improved math scores across the nation's 132,000 schools educating 58 million students. The software being developed in this project is unique in that it emulates the natural style of communication between a student and an expert math teacher and immerses students in 3D virtual worlds where they develop deep mathematical insight and solve fascinating real-world problems. The program's ability to develop both mathematical content knowledge and problem-solving skills at the same time, as well as its capability to non-intrusively assess students during the mathematical explorations is also unmatched. During the Phase II project, the commercially viable software will be fully developed and its efficacy to improve students' mathematical problem-solving skills will be thoroughly researched. A pretest-posttest control group experiment will be conducted in authentic education settings to determine efficacy. The software's educational model and content may be adjusted if necessary based on the outcome of the research.

这个SBIR第二阶段项目将开发软件，教导4 - 10年级的学生如何解决看似困难、甚至一开始可能毫无希望的数学问题。从定义上讲，问题是很难解决的。它们需要密集的思考和开放式的实验，这在今天的课堂上往往是不可能的。在该软件中，一个专家化身带领学生在视频游戏质量的3D数学探索中可视化并发现令人大开眼界的数学真理。该计划帮助教师把数学变成令人兴奋的探索，学生会喜欢。例如，当学生们乘坐大型喷气式飞机从纽约飞往东京时，他们毫不费力地发现了在球面上两点之间寻找最短路径的方法，这是一个困难的几何问题。教师可以很容易地将该程序融入日常教学中，并获得每个学生弱点的关键细节。发现的乐趣被设想为增加学生对数学，科学和工程的兴趣，并显着减少他们的数学焦虑。除了创造就业机会和税收收入，该项目预计将有助于在全国132,000所学校教育5800万学生的数学成绩显著提高。该项目中开发的软件是独一无二的，因为它模拟了学生和专业数学教师之间的自然交流方式，并使学生沉浸在3D虚拟世界中，在那里他们发展了深刻的数学见解并解决了迷人的现实问题。该计划的能力，同时发展数学内容的知识和解决问题的能力，以及其能力，非侵入性评估学生在数学探索也是无与伦比的。在第二阶段的计划中，我们会全面开发商业上可行的软件，并会深入研究该软件对提高学生解决数学问题的能力的效用。在真实的教育环境中进行前测-后测控制组实验，以确定有效性。软件的教学模式和内容可能会根据研究结果进行必要的调整。
