Self-directed learning is an important form of adult learning (Caffarella, 1993; Knowles, 1975; Knowles, Holton & Swanson, 2005; Merriam, 2001; Merriam & Caffarella, 1999). The strategies of self-directed learning allow adult learners to cope better with their studies while fulfilling family, work and other commitments. This study…

Student veteran achievement in community college has received increased attention this past decade with the surge in enrollment by returning military personnel and retired veterans. Similar to previous eras, today's student veterans seek post-war educational opportunities at postsecondary institutions. Yet unlike previous student veteran…

We examined whether the General Factor of Personality (GFP) is related to the "g" factor of cognitive ability using data from the Vietnam Experience Study which randomly sampled 4462 Vietnam War veterans from a total sample of about five million Vietnam era army veterans. Exclusionary criteria included passing a fitness test, achieving a…

Teacher efficacy is a topic of significance in mainstream education and various instruments have been developed to measure this construct. The available instruments however, are general both in terms of their subject matter and context. To compensate for this generality, the present study aims to develop a new teacher efficacy instrument whose…

Successful academic writing requires strong command of the rhetorical moves that orient the reader to the theme and substantive material of an academic essay. Effective control of the introduction leads to better overall writing. The goal of this study was to devise and evaluate a pedagogy for teaching the writing of academic essay introductions.…

The series of Working Alliance Inventories remains the most extensively researched and utilized instruments to measure the working alliance. However, these instruments have not been normed and validated among individuals on probation or parole. Therefore, this study provides psychometric properties for a modified, offender version of the Working…

Although homeless youth exhibit numerous problem behaviors, protective factors that can be targeted and modified by prevention programs to decrease the likelihood of involvement in risky behaviors are less apparent. The current study tested a model of protective factors for multiple problem behavior in a sample of 474 homeless youth (42% girls;…

This study set out to determine if the Planning, Attention, Simultaneous, Successive (PASS) cognitive processing model, a model previously investigated with children, would hold its factorial structure with adults. A collection of PASS experimental tasks were analyzed through Maximum Likelihood Factor Analysis. A four-factor solution consistent…

Normative adult age-related decrements are well documented for many diverse forms of effortful cognitive processing. However, it is currently unclear whether each of these decrements reflects a distinct and independent developmental phenomenon, or, in part, a more global phenomenon. A number of studies have recently been published that show…

A simulation study compared the performance of robust normal theory maximum likelihood (ML) and robust categorical least squares (cat-LS) methodology for estimating confirmatory factor analysis models with ordinal variables. Data were generated from 2 models with 2-7 categories, 4 sample sizes, 2 latent distributions, and 5 patterns of category…

This study tested a student survey to detect differences in instruction between teachers in a modeling-based science program and comparison group teachers. The Instructional Activities Survey measured teachers' frequency of modeling, inquiry, and lecture instruction. Factor analysis and Rasch modeling identified three subscales, Modeling and…

This dissertation presents results from a series of experiments investigating adult learning of an artificial language and the effects that input frequency (high vs. low token frequency), frequency distribution (skewed vs. balanced), presentation mode (structured vs. scrambled), and first language (English vs. Japanese) have on such learning.…

The purposes of this study were to investigate the reliability and construct validity of measures of reading component skills with a sample of adult basic education (ABE) learners, including both native and nonnative English speakers, and to describe the performance of those learners on the measures. Investigation of measures of reading components…

This study of social capital employs data from the Longitudinal Study of Adult Learning (LSAL), funded by the National Center for the Study of Adult Learning and Literacy (NCSALL) and conducted at Portland State University to increase understanding of the learning process of adults with limited formal education. It provides longitudinal data on…
