项目摘要

This EHR Core Research Project at Manhattan Community College aims to contribute new knowledge and build new theory about students' understanding of the concepts traditionally learned in a college algebra course. College algebra has consistently been identified as a barrier to student degree progress and completion, particularly for groups traditionally underrepresented in STEM fields. One part of the barrier to student progress is the lack of validated assessments to measure understanding of algebra concepts. The project will undertake this important work by building a pool of items to assess conceptual understanding and then testing and validating the database at seven different colleges and universities. The aim of this project is to generate a calibrated item pool of 200 validated questions that assess conceptual understanding in college algebra. This calibrated item pool can then be used by: 1) researchers to assess the effectiveness of curricula and teaching approaches in improving algebraic conceptual understanding; and 2) practitioners to generate diagnostic tests, the results of which could then be used to target instruction to address specific student misconceptions. This research will create the first validated calibrated item pool to test elementary algebra conceptual understanding in the college context. The research builds on initial successful work developing and validating a 22-question elementary algebra concept inventory. A calibrated item pool also will allow for multiple versions of the test to be equated, so instructors or researchers can give different students different test forms but equate the scores, thus improving exam security and the reliability of results. The concept inventory database will be validated with students from the City College of New York system, where the student population is roughly 80% non-white, 60% female, 60% Pell-grant recipients, 50% first-generation college students, and 40% for whom English was not their first language. The instrument will also be tested at six other colleges across the country to ensure generalization to different institutional contexts. The project will also produce a conceptual framework for college students' understanding of elementary algebra.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.

曼哈顿社区学院的 EHR 核心研究项目旨在贡献新知识并建立新理论，帮助学生理解传统上在大学代数课程中学习的概念。大学代数一直被认为是学生取得学位和完成学位的障碍，特别是对于传统上在 STEM 领域代表性不足的群体而言。学生进步的障碍之一是缺乏有效的评估来衡量对代数概念的理解。该项目将通过建立一个项目库来评估概念理解，然后在七所不同的学院和大学测试和验证数据库来承担这项重要的工作。该项目的目的是生成一个包含 200 个经过验证的问题的校准项目池，用于评估大学代数的概念理解。然后，这个校准的项目库可以被以下人员使用：1）研究人员评估课程和教学方法在提高代数概念理解方面的有效性； 2）从业者生成诊断测试，其结果可用于有针对性的指导，以解决特定学生的误解。这项研究将创建第一个经过验证的校准项目池，以测试大学背景下的基本代数概念理解。该研究建立在开发和验证包含 22 个问题的初等代数概念清单的初步成功工作的基础上。校准题库还允许多个版本的测试进行等同，因此教师或研究人员可以为不同的学生提供不同的测试形式，但分数相同，从而提高考试安全性和结果的可靠性。概念清单数据库将由纽约城市学院系统的学生进行验证，该系统的学生人口中大约有 80% 是非白人，60% 是女性，60% 是佩尔助学金获得者，50% 是第一代大学生， 40% 的人的母语不是英语。该工具还将在全国其他六所大学进行测试，以确保能够推广到不同的机构环境。该项目还将为大学生理解初等代数提供一个概念框架。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
