Because studies examining youth drug use often have data with a high proportion of zeros, they often do not meet the assumptions for univariate or linear regression analyses that are typically used. We demonstrate the use of zero-inflated negative binomial regression models to address excessive zeros in drug use frequency on perceptions of…

Improving graduation rates is one of the biggest missions in many universities across the country and it is surely the case on the campus of this institution. The work here presents a statistical tool box to use early academic performance as a predictor for graduation with logistic regression and machine learning techniques. The methods described…

This thesis describes how intellectual boundary spanning can be identified in the written ideas of millions of scholars, and finds that such efforts encounter translational problems which can hinder faculty careers. In particular, the work presented develops textual metrics of intellectual boundary spanning (interdisciplinarity) and field…

The educational importance of teacher self-efficacy necessitates research into variables presumed to significantly influence teacher self-efficacy. In the current study, the role of personal and programmatic variables on the self-efficacy of school-based agriculture teachers was explored. Self-efficacy was measured in five aspects of the…

This study explored whether a predictive model of student loan default could be developed with data from an institution's three-year cohort default rate report. The study used borrower data provided by a large two-year community college. Independent variables under investigation included total undergraduate Stafford student loan debt, total number…

This article presents results on how students became engaged and motivated when using digital storytelling in knowledge creation in Finland, Greece and California. The theoretical framework is based on sociocultural theories. Learning is seen as a result of dialogical interactions between people, substances and artefacts. This approach has been…

We explored the usefulness of first and second grade reading measures and responsiveness criteria collected within a response-to-intervention (RtI) framework for predicting reading disability (RD) in third grade. We used existing data from 387 linguistically diverse students who had participated in a longitudinal RtI study. Model-based predictors…

This report presents the results of a thorough study conducted by American Institutes for Research (AIR) to investigate the cost of providing an "adequate" education to California students attending public elementary, middle, and high schools. The study addresses the following question: "What is the cost of providing all California…

Since the early 1960s, there has been a steady increase in the number of students enrolled in institutions of higher education outside of their home countries. This study contributes to the information available to study abroad professionals seeking to guide students in selecting programs that are best suited to their individual characteristics…

Higher rates of school switching by students contribute to achievement disparities and are typically theorized as driven by attributes of individual pupils or families. In contrast the neoclassical-economic account postulates that switching is necessary for competition among schools. We argue that both frames fail to capture social-referential and…

This paper considers the functions of supportive individuals in the lives of community college and 4-year college students and how such support can promote hope, defined as agency and pathways thinking. We surveyed 181 college students regarding their supportive relationships and found that parents were most likely to be nominated as a primary…

The Pittsburgh Promise is a scholarship program that provides $5,000 per year toward college tuition for public high school graduates in Pittsburgh, Pennsylvania who earned a 2.5 GPA and a 90% attendance record. This study used a difference-in-difference design to assess whether the introduction of the Promise scholarship program directly…

Teacher enthusiasm for reading has considerable influence on students' reading interest and reading ability. The purpose of this study was to better understand the relationship between reading ability and reading interest among adults who plan to become teachers. This study tested whether there is a relationship between reading ability as measured…

Underidentification of students with emotional and behavioral disorders (EBD; emotional disturbance or ED in federal language) is a critical issue, perhaps explainable in part by causal attributions of problem behavior associated with conservatism. Conservatism in 58 counties in the state of California was measured by finding the percentage of…

An important question in research on eye movements in reading is whether word frequency and word predictability have additive or interactive effects on fixation durations. A fair number of studies have reported only additive effects of the frequency and predictability of a target word on reading times on that word, failing to show significant…
