Risky sexual behaviors in adolescence continue to be a social problem that impacts individuals, families, and communities across the United States. Previous research showed that parents who actively talk with their adolescents about sex and intimacy topics reduce their likelihood of engaging in these behaviors. Still, less is known about what…

Practical work involving laboratory experiments is agreed upon to be an essential component of secondary science education. Practical work encompasses a broad range of activity types. The different forms of practical work are not equal in terms of cognitive demand and learning benefit. Inquiry-based investigations provide experience of cognitive…

The goal of a triathlon is to provide a challenge to the athlete, but this comes with inherent risks. The drowning rate of triathlon participants has increased exponentially over the years in open water triathlon venues. This study sought to understand the decision-making process of experienced lifeguards in the unique conditions of the open water…

With the increase of technology in day-to-day lives, online college education is sweeping the nation as numbers of students enrolling online is consistently on the rise. Unfortunately, because of the nature of open enrollment at the community college level, students often enroll without necessary skills to be successful at the college level,…

Time management of undergraduate college students has long been studied as it relates to student success outcomes such as retention, GPA, and more. However, less is known about the way college students actually use or allocate their time and how these patterns affect student success. To address this problem, the purpose of this study was to…

This mixed methods study explores high school seniors' math course-taking decisions and what changes school leaders can take to increase the percentages of students taking four years of math in high school. Through an analysis of district-level administrative data and a survey completed by seniors at a high performing, diverse high school in…

This study examined the effectiveness of a Derived Relational Responding (DRR) program in improving reading comprehension accuracy among upper elementary students without intellectual or developmental disabilities who struggle to meet grade-level reading standards. Addressing a gap in current interventions, the study investigated whether DRR,…

In this dissertation, I describe patterns of educational placement for students with disabilities, test the degree to which placement is impacted by student and school variables, and offer practical guidance for how schools can promote the principle of least restrictive environment (LRE) to promote access to general education classrooms to the…

Adaptive reasoning is one of five components students use to develop mathematical expertise and become mathematically proficient. When students adapt their reasoning they are logically thinking about the mathematical relationships between concepts and adapting their thinking to solve problems. Three Act Math Tasks are popular math problems used in…

In this dissertation, I argue that web development can play a pivotal role in developing computational thinking as well as provide a stepping stone to an advanced mastery of computation. The preceding literature has extensively examined not only how learners practice computational thinking with a wide array of programming languages, but also how…

Effectively mastering organic chemistry means having the ability to recognize structural patterns, identify properties or behaviors as a result of patterns, manipulate and transform representations, and predict future outcomes. Often students rely on rote memorization of seemingly disconnected information instead of developing a sound…

Even with extensive retention research dating from the 1960s, community colleges still struggle to identify the reasons why students do not return to college. Data mining has allowed these retention models to evolve to identify new patterns among student populations and variables. The purpose of this study was to create a predictive model for…

Students in introductory computer science courses, are learning to program. Indeed, most students perceive that learning to code is the central topic explored in the courses. Students spend an enormous amount of time struggling to learn the syntax and understand semantics of a particular language. Instructors spend a similar amount of time reading…

The large flood of data flowing from observatories presents significant challenges to astronomy and cosmology--challenges that will only be magnified by projects currently under development. Growth in both volume and velocity of astrophysics data is accelerating: whereas the Sloan Digital Sky Survey (SDSS) has produced 60 terabytes of data in the…

A problem in computer security is identification of attack signatures in network packets. An attack signature is a pattern of bits that characterizes a particular attack. Because there are many kinds of attacks, there are potentially many attack signatures. Furthermore, attackers may seek to avoid detection by altering the attack mechanism so that…
