Students in chemistry often demonstrate difficulty with the principle of resonance. Despite many attempts to mitigate this difficulty, there have been few attempts to examine the root cause of these issues. In this study, students were assessed for their perception of Kekule structures based on perceptual learning theory, which is grounded in…

We have developed a metabolic pathways visualization skill test (MPVST) to gain greater insight into our students' abilities to comprehend the visual information presented in metabolic pathways diagrams. The test is able to discriminate students' visualization ability with respect to six specific visualization skills that we identified as key to…

As Barry Brummett (1984) has argued, the purpose of rhetorical theory is pedagogical--providing students with resources for understanding the rhetorical transactions that they encounter every day. An understanding of the implications of ideology is necessary for advanced communication students. Kellner and Share (2005) contend that this is…

The practice of using images in teaching is widespread, and in science education images are used so extensively that some have argued they are now the "main vehicle of communication" (C. Ferreira, A. Arroio "Problems Educ. 21st Century" 2009, 16, 48-53). Although this phenomenon is especially notable in the field of…

Among the elements required to develop a comprehensive understanding of music is students' ability to perceive, recognize, and label the harmonies they hear. Harmonic dictation is among the strategies that teachers have traditionally chosen to help students develop harmonic awareness. However, the highly idiosyncratic ways that students approach…

Twenty-six test variables for psychological differentiation and cognitive abilities were factor analyzed with a view towards replication of certain factors of perceptual and conceptual differentiation and related these factors to cognitive abilities. (Author)

The author investigated the importance of processing considerations within implicit memory in a developmental design. Second-graders (n = 87) and college students (n = 81) completed perceptual (word stem completion) and conceptual (category generation) implicit memory tests after studying target items either nonsemantically (read) or semantically…

In a study of the differences in images of journalism among persons with varying amounts of contact with the profession, three groups completed questionnaires. The groups were composed of 79 high school students, 55 college students majoring in journalism, and 54 professional journalists. The questionnaire included four items to measure perceived…

The purpose of the two experiments was to assess the effects of two levels of stimulus redundancy and three levels of irrelevant visual stimulation on performance in a successive discrimination task and a reproduction task. The results indicate that increases in redundancy facilitated performance in the reproduction task but had no appreciable…
