This project will build and validate learning trajectories (LTs) in mathematics for fraction, ratio, and for decimal and percent to represent learning by grades 3-7 students. A system will be developed to automate data collection for field testing assessment items to determine students' attainment of proficiency levels. Three LTs will be produced and validated along with over 125 assessment items for each of these three trajectories. These assessment items will be useful for diagnosing student learning. Technologies such as mobile phones, tablets, and computers will be used to deliver, analyze, and report diagnostic data on students. The learning trajectories will be available both electronically and in print. The levels of proficiencies will be provided with the outcome spaces, the exemplary items, the student work, and videos of student responses. Publications will provide data on analysis of the diagnostic items and assessments. The project will be done by researchers at the North Carolina State University in collaboration with RoleModel Software Inc.,and the University of Maryland.The learning trajectories will be developed through literature reviews, whole class teaching experiments, clinical interviews, and large-scale assessments. Students in grade 3 will be observed and interviewed while engaging in work on fractions, ratios, decimal, and precents. Some of these students will be observed longitudinally over the two years. Other students from grades 4 through 8 will be interviewed. For each of the three trajectories, about 150 assessment items will be developed and field tested with a large group. Three learning trajectories will be developed and made available electronically with supporting materials. The learning trajectories will be done in coordination with the Common Core State Standards (CCSS) in mathematics. Because the learning trajectories and materials will be informative to teachers who will be implementing the CCSS, the work has the potential to appeal to and reach a very large audience. Publications will provide data on analysis of the diagnostic items and assessments. The researchers will seek ways for a greater audience to have access to the software for accessing and retrieving items.

该项目将建立并验证分数、比率、小数和百分比的数学学习轨迹 (LT)，以代表 3-7 年级学生的学习情况。将开发一个系统来自动收集现场测试评估项目的数据，以确定学生的熟练程度。将针对这三个轨迹中的每一个生成并验证三个 LT 以及超过 125 个评估项目。这些评估项目将有助于诊断学生的学习情况。手机、平板电脑和计算机等技术将用于提供、分析和报告学生的诊断数据。学习轨迹将以电子版和印刷版形式提供。熟练程度将通过成果空间、示范项目、学生作业和学生回答视频来提供。出版物将提供诊断项目分析和评估的数据。该项目将由北卡罗来纳州立大学的研究人员与 RoleModel Software Inc. 和马里兰大学合作完成。学习轨迹将通过文献综述、全班教学实验、临床访谈和大规模评估来制定。三年级学生在学习分数、比率、小数和百分比时将受到观察和采访。其中一些学生将在两年内进行纵向观察。其他 4 至 8 年级的学生也将接受采访。 对于这三个轨迹中的每一个，都将开发约 150 个评估项目，并由一大群人进行现场测试。 将开发三个学习轨迹并以电子方式提供支持材料。学习轨迹将与数学领域的共同核心国家标准（CCSS）协调一致。由于学习轨迹和材料将为实施 CCSS 的教师提供信息，因此这项工作有可能吸引并接触到大量受众。出版物将提供诊断项目分析和评估的数据。研究人员将寻求让更多受众能够使用该软件来访问和检索项目的方法。
