In this article, the authors examine the interconnections among education researchers' misconceptions about the quality of the education research literature. Specifically, the authors catalog the sequence of events that, when taken together with a series of contradictory graphs presented by influential scholars in prominent settings, may have…

In his article, "An Alternative to Null-Hypothesis Significance Tests," Killeen (2005) urged the discipline to abandon the practice of "p[subscript obs]"-based null hypothesis testing and to quantify the signal-to-noise characteristics of experimental outcomes with replication probabilities. He described the coefficient that he…

The sense that replicability is an important aspect of empirical science led Killeen (2005a) to define "p[subscript rep]," the probability that a replication will result in an outcome in the same direction as that found in a current experiment. Since then, several authors have praised and criticized 'p[subscript rep]," culminating…

"Multitasking" has developed a certain mantra in our culture, and according to this widely held axiom, people in general and students in particular, can and do function productively and learn efficiently doing several things at once. There also seems to be an unshakable conviction that young students excel in a multitasking environment.…

Why, during a decision between new alternatives, do people bias their evaluations of information to support a tentatively preferred option? The authors test the following 3 decision process goals as the potential drivers of such distortion of information: (a) to reduce the effort of evaluating new information, (b) to increase the separation…

Recent articles in "Teaching of Psychology" have endorsed the classroom use of various mnemonic techniques. Yet a degree of mnemonophobia (i.e., fear of using mnemonics) may persist in the minds of some "ToP" readers due to various lingering misconceptions. In this regard, we conducted 3 practical experiments with college students using the…

Confidence intervals are beginning to play an increasing role in the reporting of research findings within the social and behavioral sciences and, consequently, are becoming more prevalent in beginning classes in statistics and research methods. Confidence intervals are an attractive means of conveying experimental results, as they contain a…

Plant tropisms--their directional movement in response to stimuli--are a fundamental concept in plant science and excite students because they are the observable signs of life in plants. Unfortunately, the precollege teaching literature is full of tropism misconceptions. An inexpensive clock clinostat is invaluable for student gravitropism and…
