The purpose of this quantitative study was to determine if the outcome of two different types of referendums, operating fund and construction, could be more accurately predicted by using certain predictor variables. Furthermore, if the outcome could be more accurately predicted, which predictor variables were statistically significant in that…

This study compared accuracy of energy expenditure (EE) prediction models from accelerometer data collected in structured and simulated free-living settings. Twenty-four adults (mean age 45.8 years, 50% female) performed two sessions of 11 to 21 activities, wearing four ActiGraph GT9X Link activity monitors (right hip, ankle, both wrists) and a…

Field experiments in education frequently assign entire groups such as schools to treatment or control conditions. These experiments incorporate sometimes a longitudinal component where for example students are followed over time to assess differences in the average rate of linear change, or rate of acceleration. In this study, we provide methods…

We report an experiment designed to provide a qualitative contrast between knowledge-limited versions of mixed-state and variable-resources (VR) models of visual change detection. The key data pattern is that observers often respond "same" on big-change trials, while simultaneously being able to discriminate between same and small-change…

The extent to which social norms (injunctive and descriptive) are associated with collegiate alcohol use--including binge drinking--has been examined at length, but studies examining the efficacy of interventions derived thereof have reported mixed outcomes. This study examines data from 5,124 college students at 13 different colleges collected by…

This study investigates whether age-related changes in the structure of 5 complex working memory (WM) tasks (a) reflect a general or domain specific system, (b) follows a similar trajectory across different age spans, and (c) contribute domain general or domain specific resources to achievement measures. The study parsed the sample (N = 2,471)…

This article discusses a financial training program used by Deere and Company for almost 10 years. The objective is to describe the program and to discuss a pre-test/post-test methodology to test the effectiveness of a program for possible duplication by Extension. Results show that participants significantly improved from the pre-test to the…

New analytical tools have facilitated the exploration of the trajectories of alcohol use; however, there are a limited number of studies that explore early adolescence. A sample of 5,903 youths followed from sixth through eighth grade was used to (1) examine the trajectories of alcohol use and (2) determine the degree to which common correlates…

Systems of care can be used to help coordinate and direct resources both external and internal to a school, thereby providing critical supports for students with emotional and behavioral challenges that historically have not been available to educators. In this study, hierarchical linear modeling was used to longitudinally examine school…

In this study, we assessed small and large group discussions and repeated writing assignments with the intent to objectively measure the values of these learning pedagogies. We crafted a model where students researched a question, formulated a written answer, discussed it with their peers, and revised their answers. Then, we did it with repetition…

This study compared the model-data fit of a parametric item response theory (PIRT) model to a nonparametric item response theory (NIRT) model to determine the best-fitting model for use with ordinal-level alternate assessment ratings. The PIRT Generalized Graded Unfolding Model (GGUM) was compared to the NIRT Mokken model. Chi-square statistics…

Describes a conceptual model representing the demand and supply of public school teachers and the relationship between the assessed valuation of property within a school district and the training, experience, and salary levels of teachers in the district, based on an analysis of data from 269 Indiana school districts.
