Human capital theory suggests the knowledge, skills, and abilities one obtains through experience, on-the-job training, or education enhances one's productivity. This research was based on human capital theory and promotability (i.e., upward mobility). The research offered in this dissertation shows what effect obtaining information security…

This thesis deals with "large-scale" detection problems that arise in many real world applications such as sensor networks, mapping with mobile robots and group testing for biological screening and drug discovery. These are problems where the values of a large number of inputs need to be inferred from noisy observations and where the…

The purpose of this study was to determine if grade level configuration and student achievement in science, specifically fifth grade Science TAKS scores are related. This study utilized a causal comparative (ex post facto) design to determine if a consistent relationship existed between fifth grade students' success on the science TAKS at the…

Standardized tests are often required to gain admission into postsecondary schools or to obtain professional certifications. Federal disability laws, such as the Americans with Disabilities Act (ADA) require entities that administer these tests to provide accommodations, such as extended time or changes in test format, to students with…

On assessments such as Trends in International Mathematics and Science Study (TIMSS) (Stigler & Hiebert, 1999) and Program for International Assessment (PISA) ("PISA 2006 Science Competencies for Tomorrow's World", 2007) students in the United States have not been performing as well in mathematics as students in other countries. In…

A comprehensive assessment system is one in which three types of assessments: summative, benchmark, and formative assessments are routinely administered to all students in K-12 classrooms. The first part of this report summarizes the research on comprehensive assessment systems and provides clarity in terms of how each individual assessment type…

In an era of financial stringency and demands for better school performance, it is useful to think about several means of raising school productivity: (1) increase learning effectiveness without increasing costs; (2) reduce costs without diminishing effectiveness; or (3) both, that is, increase effectiveness and simultaneously reduce costs. The…

Since the 1990s, a wealth of literature has compared the benefits of having a GED[R] test credential versus a traditional high school diploma or no high school credential, with an early emphasis on economic impact. One advantage of passing the GED test lies in its ability to open doors to the postsecondary system. Nearly two-thirds of U.S.…

This research was conducted approximately one year after Egyptian Agricultural Technical School (ATS) instructors attended workshops on integrating placement Supervised Agricultural Experience as an instructional tool in their programs. Following a year of implementation, the purpose of this study was to determine ATS teacher knowledge and ability…

Science education in the United States will increasingly be driven by testing and accountability requirements, such as those mandated by the No Child Left Behind Act, which rely heavily on learning outcomes, or "standards," that are currently developed on a state-by-state basis. Those standards, in turn, drive curriculum and instruction.…

This article adds to current research on enhancing student discourse in mathematics teaching specifically in secondary schools but with equal relevance to elementary schools. Three mathematics teachers in secondary education were confronted with the question of how to encourage students to discuss their work with each other in the daily practice…

Presymptomatic genetic testing generates socioscientific issues in which decision making is complicated by several complexity factors. These factors include weighing of advantages and disadvantages, different interests of stakeholders, uncertainty of genetic information and conflicting values. Education preparing students for future decision…

We examined the measurement properties of fall-related psychological instruments with a sample of 133 older adults (M age = 74.4 years, SD = 9.4). Measures included the Comprehensive Falls Risk Screening Instrument, Falls-efficacy Scale-International (FES-I), Activities-specific Balance Confidence (ABC), modified Survey of Activities and Fear of…

The Test of Variables of Attention (TOVA) is a continuous performance test (CPT) that assesses attention, impulsivity, and processing speed. CPTs are used in the assessment of attention-deficit/hyperactivity disorder (ADHD) in children, but more young adults are being assessed for ADHD as well. The TOVA norms are based on a standardization sample…

Introduction: Limited information exists to describe physicians who return to practice after absences from patient care. The Center for Personalized Education for Physicians (CPEP) is an independent, not-for-profit organization that provides clinical competency assessment and educational programs for physicians, including those reentering…
