Research on the relationship between socioeconomic status and educational outcomes of students is abundant, but research related to factors that are capable of mediating the effects of poverty on the education of children is lacking. The purpose of this study is to provide a better understanding of such factors. A pilot study using The High School…

The number of students of community college students in need of remedial math courses continues to increase each year; however, the success and retention rate for student enrolled in remedial math courses remains extremely low. The purpose of this study was to examine factors students characterize as impeding their ability to successfully complete…

College Algebra is a gatekeeper course that serves as an obstacle for many students pursuing STEM careers. Lack of success in this course could be a key reason why the United States lags behind other industrialized countries in the number of students graduating with STEM majors and joining the STEM workforce. Of the many topics presented in…

The purpose of this study was to compare student performance in online and traditional classroom based developmental math courses at Texas community colleges. This study specifically examined: (a) student performance in both delivery methods, (b) students who successfully completed the developmental math course, and (c) student performance in the…

Due in part to the growing popularity of the Advanced Placement program, an increasingly large percentage of entering college students are enrolling in calculus courses having already taken calculus in high school. Many students do not score high enough on the AP calculus examination to place out of Calculus I, and many do not take the…

Developmental mathematics is one of the most challenging leaks in the mathematics K-20 pipeline. Few students enter two-year colleges prepared to successfully engage in college-level mathematics classes. Many of students who place into developmental mathematics are low-income, underprepared, students of color, and many are not equipped with the…

Becoming a skillful prover is critical for success in advanced undergraduate and graduate mathematics courses. In this dissertation, I report my investigations of proof and the proving process in three separate studies. In the first study, I examined the amount of logic used in student-constructed proofs to help in the design of…

Community colleges face many challenges in the face of demands for increased student success. Institutions continually seek scalable interventions and initiatives focused on improving student achievement. Effectively implementing sustainable change that moves the needle of student success remains elusive. Facilitating systemic, scalable change…

As computing becomes ubiquitous, software correctness has a fundamental role in ensuring the safety and security of the systems we build. To design and develop software correctly according to their formal contracts, CS students, the future software practitioners, need to learn a critical set of skills that are necessary and sufficient for…

Students experience difficulty learning and understanding chemistry at higher levels, often because of cognitive biases stemming from common sense reasoning constraints. These constraints can be divided into two categories: assumptions (beliefs held about the world around us) and heuristics (the reasoning strategies or rules used to build…

The author studied how math anxiety, motivation, and ability group interact to affect performance in college math courses. This clarified the effects of math anxiety and ability grouping on performance. It clarified the interrelationships between math anxiety, motivation, and ability grouping by considering them in a single analysis. It introduces…

This study evaluated the effectiveness of developmental math, English, and reading courses by evaluating the success of students in the corresponding college-level math, English, and reading course. This study analyzed select student characteristics (sex, ethnicity, age, socioeconomic status) or student developmental education status as predictors…

The purpose of this study was to investigate whether high student accountability and formative assessment affected student motivation, learning and resource management strategies, and achievement in developmental algebra I. The setting was a fifteen-week semester at a community college in suburban New York. Two sections of developmental algebra I…

The purpose of this quantitative quasi-experimental study is to determine the effectiveness of a corequisite delivery model for developmental math students at a 4-year public institution. Nationally, close to fifty percent of incoming college students are placed in non-credit bearing remedial courses (Complete College America, 2012). Students must…

Low levels of student success in introductory college math courses are rampant. There are several reasons for low pass rates in these courses, with the most serious issue being lack of concept mastery. To aid students in concept mastery, adaptive learning systems were created. These systems adapt instruction for each student and create an…
