Community colleges are truly an American invention that, despite many documented successes, remains controversial. There is a large body of research that criticizes these institutions citing non-successes (Dougherty, 1987, 1994; Brint & Karabel, 1989). Debates whirl not only about the overall outcomes of these institutions, but also about how to…

This paper describes the process for employing two principal instruments for relating the categories identifying the central phenomenon in grounded theory analysis. The Conditional Relationship Guide contextualizes the central phenomenon and relates structure with process. The second tool, the Reflective Coding Matrix, captures the higher level of…

We investigated the role of acetylcholine (ACh) during encoding and retrieval of tone/shock-induced fear conditioning with the aim of testing Hasselmo's cholinergic modulation model of encoding and retrieval using a task sensitive to hippocampal disruption. Lesions of the hippocampus impair acquisition and retention of contextual conditioning with…

This paper discusses the ethical issues associated with analysis of computer conference transcripts and the value of validating the interpretations of such transcripts with other data sources. Based on the study of a graduate level online course recently taught at a major American public university, this paper attempts to demonstrate how failures…

This article aims at analyzing laddering as a technique of qualitative research, emphasizing the procedures for data collection, analysis and interpretation, and its main limitations as well. "Laddering refers to an in-depth, one-on-one interviewing technique used to develop an understanding of how consumers translate the attributes of products…

Students in statistics service courses are frequently exposed to dogmatic approaches for evaluating the role of randomization in statistical designs, and inferential data analysis in experimental, observational and survey studies. In order to provide an overview for understanding the inference process, in this work some key statistical concepts in…

The purpose of this research study was to (a) describe how concept mapping can be used as an integral instructional strategy for teaching a college course in evolution, (b) evaluate the utility of incorporating concept mapping in a college course on evolution, (c) determine whether students' concept maps reveal "critical junctures" in learning as…

The authors present a method that ensures control over the Type I error rate for those who visually analyze the data from response-guided multiple-baseline designs. The method can be seen as a modification of visual analysis methods to incorporate a mechanism to control Type I errors or as a modification of randomization test methods to allow…

Much of the research on psychopathy has treated it as a unitary construct operationalized by total scores on one (or more) measures. More recent studies on the Psychopathic Personality Inventory (PPI) suggest the existence of two distinct facets of psychopathy with unique external correlates. Here, the authors report reanalyses of two offender…

Upon reviewing the extant literature on determinants of unionism, it becomes clear that many areas that have had a plethora of research attention do not converge upon singularly directional findings. This study explores a potential cause of such an apparent anomaly: nonlinearity of data. An exploratory examination of correlation coefficients among…

Objective: To determine the proportion of youth suicides in New York City from 1999 to 2002 in which antidepressants were detected at autopsy. Method: This is a medical examiner surveillance study of suicides in New York City among those younger than 18 years of age. The outcome measure is serum toxicology for antidepressants. Results: From 1999…

An experiment is described, which is designed for a junior-level chemical engineering "fundamentals of measurements and data analysis" course, where students are introduced to the concept of statistical process control (SPC) through a simple inline mixing experiment. The students learn how to create and analyze control charts in an effort to…

This study examines the demographic, academic, social, and behavioral differences between GED (General Educational Development) candidates who were and were not retained in grade. Differences between candidates who were and were not retained in grade are examined with regard to factors such as demographics, delinquent behaviors, reasons for…

The study explored the origins of students' data handling knowledge and skills employed during secondary Science lessons. Transfer of learning was explored in an authentic school context, describing when transfer does and does not occur, conditions that appear to foster transfer, and impacts of different types of transfer on teaching and learning.…

We explore three analytic methods that can be used to quantify and qualify changes in attitude and similar outcomes that may be encountered in the educational context. These methods can be used or adapted whenever the outcome of interest is change in a generally unmeasurable attribute, such as attitude. The analyses we describe focus on: (1)…
