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…

THE EFFECTS OF INSTRUCTIONS, TYPE OF LABEL, TYPE OF CONCEPT, AND SEQUENCE OF CONCEPTS BY TYPE UPON CONCEPT IDENTIFICATION WERE INVESTIGATED IN THIS STUDY. PERFORMANCE WAS ANALYZED IN TERMS OF FOUR TYPES OF TEST ITEMS. INSTRUCTION, FOCUSING ON THE CONCEPT TO BE ATTAINED AND THE CONCEPT NATURE, WAS FOUND TO FACILITATE CONCEPT IDENTIFICATION…

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)

Two experiments examining adults' use of dimensional adjectives focused specifically on the distinction made between height and overall size as determiners of "bigness." The subjects in both experiments were college students. In the first, the hypothesis that the meaning of "big" shifts as a function of the object being…

This study was designed as the first in a series of inquiries to investigate the use of multidimensional scaling techniques for observing and measuring underlying dimensions commonly perceived by viewers. Following a preliminary study to select photographs, 15 university students aged 19 to 45 were presented with stimuli consisting of 34 colored…

Through everyday experience people acquire knowledge about how moving objects behave. For example, if a rock is thrown up into the air, it will fall back to earth. Research has shown that people's ideas about why moving objects behave as they do are often quite inconsistent with the principles of classical mechanics. In fact, many people hold a…

Two semantic theories of word learning, a perceptual complexity hypothesis (H. Clark, 1970) and a quantitative complexity hypothesis (E. Clark, 1972) were tested by teaching 24 preschoolers and 16 college students CVC labels for five polar spatial adjective concepts having single word representations in English, and for three having no direct…
