The purpose of this paper is to discuss the development of research questions in mixed methods studies. First, we discuss the ways that the goal of the study, the research objective(s), and the research purpose shape the formation of research questions. Second, we compare and contrast quantitative research questions and qualitative research…

This article has three purposes: to explain the two different uses of power analysis that can be used in health education research; to examine the extent to which power analysis is being used in published health education research; and to explain the implications of not using power analysis in research studies. Articles in seven leading health…

We describe a principled way of imposing a metric representing dissimilarities on any discrete set of stimuli (symbols, handwritings, consumer products, X-ray films, etc.), given the probabilities with which they are discriminated from each other by a perceiving system, such as an organism, person, group of experts, neuronal structure, technical…

Stevens postulated that we can use the responses of a participant in a ratio scaling experiment directly to construct a psychophysical function representing the participant's sensations. Although Stevens' methods of constructing measurement scales are widely used in the behavioral sciences, the problem of which scale type is appropriate to…

In this study, the authors examined how overreporting of psychopathology indices on the Personality Assessment Inventory (PAI; L. C. Morey, 1991) performed as screening measures for malingering in a sample of 166 defendants undergoing pretrial court-ordered evaluations in the federal criminal justice system. Using results from the Structured…

This article presents 7 simple models of the relationship between cognitive empathy (mental perspective taking) and emotional empathy (the vicarious sharing of emotion). I consider behavioral outcomes of the models, arguing that, during human evolution, natural selection may have acted on variation in the relationship between cognitive empathy and…

This paper introduces and compares three types of college level teaching: discussion, lecture, and personalized systems. The discussion method is described and identified as one that allows the learner to question and probe, giving increased internalization, greater acceptance of conclusions than other teaching methods, and other benefits. The…

This paper examines collaborative action research in order to clarify the arguments and research base that either support or oppose the process. Proponents who advocate the institutionalization of collaborative action research point to its theoretical rationale, a growing research base that documents the value and outcomes of the process, and…

This paper attempts to reformulate some assumptions of contemporary social science so that its knowledge becomes directly applicable in social action. A schema is presented for the interpretation of social experience in which sociological, anthropological, and psychological knowledge and knowledge of the physical and biological world enter into a…

One approach to language learning unites insight into explicit rules, systematic drill and contextual communication. By thinking, creating and speaking, language rules are created and transferred to other situations. Repeated remodelling of sentences seems to yield fastest learning. (CHK)

Introduction: We explored Harris and Dewdney's principle that people follow habitual patterns when seeking everyday information along with Pettigrew's notion of information grounds. Method: A telephone survey of 612 urban-rural residents was conducted regarding their needs for health and human services in partnership with the United Way of…

Concern over the validity of statistical tests performed on data that may not satisfy underlying assumptions has prompted methodological researchers to perform Monte Carlo studies for frequently used tests. Unfortunately, these studies appear to have had little impact on methodological practice. One reason is the lack of an overarching framework…

This study used a five-phased, multi-modal research design to develop a pedagogical plan for collaborative learning in freshman composition classrooms, a plan intended to improve student writing within a collaborative environment and be readily adaptable to a range of teaching contexts. The five-phased project used the following methods: (1)…

The effects of wait-time, the pause following a teacher question and the pause after a student response, on the length and number of student responses were analyzed at different cognitive levels. Data were obtained from 95 students in grade 4 and from 5 teachers using a wait-time of 5 seconds. Four oral discussion sessions by teachers and students…

The primary purpose of this paper is to examine negative findings regarding the use of simulations in economics education and to make suggestions for effective use of computerized economic simulations. The first part of the paper reviews experiential learning theory and previous economics education studies by Wentworth and Lewis (1972); Chismar,…
