Two basic data sources required for research studies have been secondary and primary. Secondary data collection helps the researcher to provide relevant background to the study and are, in most cases, available for retrieval from recorded sources. Primary data collection requires the researcher to venture into the field where the study is to take…

Objective: Describe lay food group categories of low-income African American women and assess the overlap of lay food groups and MyPyramid food groups. Design: A convenience sample of African American mothers from a low-income Chicago neighborhood performed a card-sorting task in which they grouped familiar food items into food groups. Setting:…

While previous research has indicated that learners with field-dependence (FD) and field-independence (FI) cognitive styles benefit differentially from different instructional modes, previous corrective feedback studies have ignored the issue of matching error correction strategies to learners' cognitive style. To shed some light on this issue,…

The increases in tuition and fee prices in 2015-16 were, like the increases in the two preceding years, relatively small by historical standards. However, the very low rate of general inflation makes this year's increases in college prices larger in real terms than those of 2014-15 and 2013-14. Significantly, and perhaps counter to public…

This research examined how differences in category structure affect category learning and category representation across points of development. The authors specifically focused on category density--or the proportion of category-relevant variance to the total variance. Results of Experiments 1-3 showed a clear dissociation between dense and sparse…

Writing a faulty literature review is one of many ways to derail a dissertation. This article summarizes some pivotal information on how to write a high-quality dissertation literature review. It begins with a discussion of the purposes of a review, presents taxonomy of literature reviews, and then discusses the steps in conducting a quantitative…

Since 2006, the details of bodies making up our solar system have been revised. This was largely as a result of new discoveries of a number of planet-like objects beyond the orbit of Pluto. The International Astronomical Union redefined what constituted a planet and established two new classifications--dwarf planets and plutoids. As a result, the…

In 2007 a South African study examined new concept formation from early childhood to adulthood (N = 60, 3 to 76 years old) using the Vygotsky/Sakharov Blocks procedure (also known as the functional method of double stimulation for the study of concept formation) to establish whether contemporary adults and children produced the same or similar…

Interest in modeling the structure of latent variables is gaining momentum, and many simulation studies suggest that taxometric analysis can validly assess the relative fit of categorical and dimensional models. The generation and parallel analysis of categorical and dimensional comparison data sets reduces the subjectivity required to interpret…

Every aspect of higher education today is pressed to become more accountable and more transparent. The field of continuing education (CE) is no different. CE professionals, responsible for the operations of university-based CE units, are constantly challenged to use data and "evidence" to make and justify decisions. Indeed, one measure of the…

Recent research on the learning process has shown that students tend to learn in different ways and that they prefer to use different teaching resources as well. Many researchers agree on the fact that learning materials shouldn't just reflect of the teacher's style, but should be designed for all kinds of students and all kind of learning styles.…

There are many different models or approaches to doing program evaluation. Fitzpatrick, Sanders, and Worthen classify them into five general approaches: (a) objectives oriented, (b) management oriented, (c) consumer oriented, (d) expertise oriented, and (e) participant oriented. Within each of these general categories, of course, reside many…

Naive observers typically perceive some groupings for a set of stimuli as more intuitive than others. The problem of predicting category intuitiveness has been historically considered the remit of models of unsupervised categorization. In contrast, this article develops a measure of category intuitiveness from one of the most widely supported…

Mintz (2003 ) described a distributional environment called a frame, defined as the co-occurrence of two context words with one intervening target word. Analyses of English child-directed speech showed that words that fell within any frequently occurring frame consistently belonged to the same grammatical category (e.g. noun, verb, adjective,…

In this paper I argue for a property-driven approach to phonological typology. Rather than seeking to classify or label languages, the central goal of phonological typology is to determine how different languages systematize the phonetic substance available to all languages. The paper focuses on a very murky area in phonological typology,…
