The subject of research methods is often unknown, foreboding, and unappealing to undergraduate communication majors. Thus, in the research methods course, two ways to overcome such issues and achieve learning are by: (1) making the unfamiliar more familiar and accessible; and (2) placing abstract knowledge in its useful real-world context. Making…

The reaction that occurs when Mentos are added to bottled soft drinks has become a staple demonstration in earth science courses to explain how volcanoes erupt. This paper presents how this engaging exercise can be used in a marketing research course to provide hands-on experience with problem formation, hypothesis testing, and causal research. A…

The genome projects of the past decades have created extensive databases of biological information with applications in both research and education. We describe an inquiry-based exercise that uses one such database, the National Center for Biotechnology Information Influenza Virus Resource, to advance learning about influenza. This database…

In this article, the authors address the practicalities of how data should be presented, summarized, and interpreted. There are no exact rules; indeed there are valid concerns that exact rules may be inappropriate and too prescriptive. New procedures evolve, and new methods may be needed to deal with new types of data, just as people know that new…

A course design for first-year science students is described, where the focus is on the skills necessary to do science. The course uses original research projects, designed by the students, to teach a variety of skills including reading the scientific literature, hypothesis development and testing, experimental design, data analysis and…

Deliberate practice--meaning drill-like practice under the direction of a coach--is key to developing expertise in sports and music. But working professionals and businesspeople typically have no time for practice. We propose deliberate performance as a type of practice that professionals and businesspeople can pursue while they work as a way to…

We should dispense with use of the confusing term "null hypothesis" in educational research reports. To explain why the term should be dropped, the nature of, and relationship between, scientific and statistical hypothesis testing is clarified by explication of (a) the scientific reasoning used by Gregor Mendel in testing specific…

The purpose of the recently proposed "p[subscript rep]" statistic is to estimate the probability of concurrence, that is, the probability that a replicate experiment yields an effect of the same sign (Killeen, 2005a). The influential journal "Psychological Science" endorses "p[subscript rep]" and recommends its use…

This paper discusses what chemistry students might see while working with animations found on the Internet and how these electronic illustrations can potentially interact to reinforce rather than resolve misconceptions about chemical principles that a student may possess. The Daniell voltaic cell serves as an example to illustrate the ways in…

The hierarchical linear model (HLM) is now commonly accepted as a useful modeling approach for multilevel data resulting from randomized field experiments. When multiple outcomes of interest exist, a multivariate extension of the conventional univariate HLM offers advantages over the usual application of separate HLM analyses for each of the…

This article describes the history, evidence warrants, and evolution of the Center for Research on Evaluation, Standards, and Student Testing's (CRESST) model-based assessments. It considers alternative interpretations of scientific or practical models and illustrates how model-based assessment addresses both definitions. The components of the…

Describes student-led research projects conducted at the University of Florida's General Clinical Research Center. First-year medical and M.D.-Ph.D. students collaborate on a hypothesis-driven experiment involving students as volunteer subjects and investigators. Feedback indicates students find the program useful and that it encourages pursuit of…

We describe a perceptual experiment that we have successfully used in Research Methods classes. Students attempt to identify a series of simple cookie cutter shapes using only the fingers and hands (haptic perception). Students read archival studies that have used this procedure, identify confounds, generate and test alternate hypotheses, and…
