DESCRIPTION (provided by applicant): The purpose of this application is to request career development support (two years mentored, three years independent) to acquire and develop knowledge and skills for conducting independent research on the cognitive and neuropsychological influences of math achievement among adolescents and young adults. For many individuals, the development of higher level mathematical skills and knowledge (e.g., algebra and calculus) is critical to achieving their full potential. These mathematical abilities are a manifest requirement for the development of knowledge in many disciplines including the physical and behavioral sciences, technology, and business. Algebra and calculus courses have also become a prerequisite for access to educational and economic opportunities because they are used as indicators of an individual's potential for post-secondary academic achievement. A large number of adolescents and young adults, who have not been identified as deficient in mathematical ability prior to middle and high school, fail to achieve proficiency in higher level mathematics. The goal of the career development plan is to provide the foundation for research that will identify sources of individual and developmental differences in higher level mathematical ability, determine indicators of students who may require specific intervention in order to acquire higher level math skills, and develop interventions that will improve the developmental trajectory of these students. Training will focus on five areas: (1) research methodology and statistics, (2) cognitive and neuropsychological development, (3) mathematics content and its role in other science disciplines, (4) research in schools, and (5) grant writing. The mentored and independent phase studies will focus on algebra achievement. During the mentored phase, algebra measures will be developed and tested in middle and high school algebra classes. Factor analysis will be used to determine if algebra achievement represents one or multiple constructs (e.g., procedural vs. conceptual knowledge). Item response theory will be used characterize the difficulty and discrimination of algebra items. The independent phase study will evaluate growth in algebra achievement among middle and high school students. Arithmetical ability and cognitive resources (e.g., processing speed) will be evaluated as predictors of algebra achievement. PUBLIC HEALTH RELEVANCE: Students who are proficient in algebra have better educational and economic outcomes than those lacking in these skills. This research will provide evidence as to why many students struggle to acquire these skills. It will also provide a basis for the development of measures to identify students who are likely to struggle in higher level mathematics and interventions to help these students.

描述（由申请人提供）：本申请的目的是请求职业发展支持（两年，三年独立），以获取和发展知识和技能，以对青少年和年轻人对数学成就的认知和神经心理学影响进行独立研究。对于许多人来说，更高级别的数学技能和知识（例如代数和微积分）的发展对于发挥其全部潜力至关重要。这些数学能力是许多学科中知识发展的明显要求，包括物理和行为科学，技术和业务。代数和微积分课程也已成为获得教育和经济机会的先决条件，因为它们被用作个人获得大专学术成就潜力的指标。许多青少年和年轻人在中学和高中之前尚未被确定为数学能力不足，他们无法熟练地精通高级数学。职业发展计划的目的是为研究提供基础，以确定高级数学能力的个人和发展差异的来源，确定可能需要特定干预以获得更高级别数学技能的学生的指标，并开发将改善这些学生的发展轨迹的干预措施。培训将侧重于五个领域：（1）研究方法论和统计学，（2）认知和神经心理学发展，（3）数学内容及其在其他科学学科中的作用，（4）学校的研究以及（5）授予写作。受过指导的独立阶段研究将集中于代数成就。在指导阶段，将在中学和高中代数类中制定和测试代数措施。因子分析将用于确定代数成就是否代表一个或多个构造（例如程序与概念知识）。项目响应理论将被用来表征代数项目的困难和歧视。独立阶段研究将评估中学生和高中生的代数成就的增长。算术能力和认知资源（例如，处理速度）将被评估为代数成就的预测指标。 公共卫生相关性：精通代数的学生比缺乏这些技能的学生更好地教育和经济成果。这项研究将提供证据表明为什么许多学生都在努力获得这些技能。它还将为制定措施的基础提供基础，以确定可能在高层数学和干预措施中挣扎的学生，以帮助这些学生。
