Completing the Development of the Electronic Test of Early Numeracy (e-TEN)

该项目由Discovery Research Pre-K-12计划资助，该计划资助STEM创新和评估，教学和学习方法的研究和开发。探索研究preK-12计划（DRK-12）旨在通过研究和开发创新资源，模型和工具，显着提高preK-12学生和教师的科学，技术，工程和数学（STEM）的学习和教学。该项目继续并完成了英语和西班牙语的早期算术电子测试（e-TEN）的开发和完善，专注于年轻学习者的数量和操作。该评估采用了学习轨迹方法，描述了学生对数字理解的发展。电子评估允许测试适应学生的反应，并纳入游戏，增加儿童对任务的参与。这些特点利用了电子格式。成绩测试的目的是高效，用户友好，负担得起，并为各种学习环境和广泛的年龄范围的学生（3至8岁）。评估设计的目标是创造一种比现有措施更准确、更广泛的儿童更容易获得和更容易管理的措施。拟议的活动还包括建立10个独立但等同的计算机适应性测试，以产生一个完整的3 - 8岁的通用规模结构，捕捉10个6个月间隔的算术能力变化。这些努力将以英文和西班牙文进行验证，符合国家规范。e-TEN评估数字和运算领域的非正式和正式知识，包括口头计数，编号，数字关系，以及心理加法和减法。这些项目是使用基于领域的学习轨迹来设计的，这些轨迹描述了学生对数字主题理解的发展。该测试的设计具有一些关键特性。它是半适应超过六个月的年龄跨度。它采用电子格式，便于统一执行和高效、方便用户的管理。西班牙语使用者可以使用跨多个平台的包容性评估模型进行测试。基于游戏的方面增加了儿童的参与度，并提出了更有意义的任务。方便用户的方面包括与其他幼儿算术测试相比简化了评估过程。开发的第一阶段是测试e-TEN的初步版本，以测试其功能和可行性。这些后期阶段规范的项目，并检查其可靠性和有效性的特点。信度采用项目反应理论方法和重测信度措施进行评估。效度检验标准预测效度和其他方面的结构效度。这项工作的最后阶段包括创建一个西班牙语版本的测试，包括收集数据，从双语儿童使用两个版本的e-TEN计算措施。这个奖项反映了NSF的法定使命，并已被认为是值得的支持，通过评估使用基金会的智力价值和更广泛的影响审查标准。

This project is funded by the Discovery Research Pre-K-12 Program, which funds research and development of STEM innovations and approaches in assessment, teaching, and learning. The Discovery Research preK-12 program (DRK-12) seeks to significantly enhance the learning and teaching of science, technology, engineering, and mathematics (STEM) by preK-12 students and teachers, through research and development of innovative resources, models, and tools.The project continues and completes the development and refinement of an electronic Test of Early Numeracy (e-TEN) in English and Spanish, focused on number and operations for young learners. The assessment incorporates a learning trajectory approach that describes students' development of the understanding of number. The electronic assessment allows for the test to adapt to students' responses and incorporate games increasing children's engagement with the tasks. These features take advantage of the electronic format. The achievement test is designed to be efficient, user-friendly, affordable, and accessible for a variety of learning environments and a broad age range of students (3 to 8 years old). The goal of the assessment design is to create a measure that is more accurate, more accessible to a wider range of children, and easier to administer than existing measures. The proposed activities also include establishing 10 separate but equated computer adaptive tests to produce a complete commonly scaled construct for ages 3-8, capturing change in numeracy ability across 10 six-month intervals. These efforts will be validated in both English and Spanish with national norms. The e-TEN assesses informal and formal knowledge of number and operations in domains including verbal counting, numbering, numerical relationships, as well as mental addition and subtraction. The items are designed using domain-based learning trajectories that describe students' development of understanding of the numerical topics. The test is designed with some key characteristics. It is semi-adaptive over six-month age spans. It has an electronic format that allows for uniform implementation and an efficient, user-friendly administration. The test is accessible to Spanish speakers using an inclusive assessment model across a number of platforms. The game-based aspect increases children's engagement and presents more meaningful tasks. The user-friendly aspect includes simplifying the assessment process compared to other tests of numeracy in early childhood. The first phase of the development tests a preliminary version of the e-TEN to test its functionality and feasibility. These later phases norm the items, and examines its reliability and validity characteristics. Reliability is assessed using Item Response Theory methods and test-retest reliability measures. Validity examines criterion-prediction validity and other aspects of construct validity. The final phase of the work includes creating a Spanish version of the test including collecting data from bilingual children using both versions of the e-TEN numeracy measure.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
