The present study extends this practice to graphic imagery by obtaining norming data on 24 simple abstract graphic shapes composed of three straight-line segments. The attributes obtained in the norming procedure were the shapes’ familiarity, describability, associability, availability, and potential for word association. Results from rating data indicate significantly different, yet reliable, responses by participants to the various shape configurations. Multidimensional scaling analysis of shape ratings identified two underlying dimensions of perceived differences: thecontinuity of a shape’s linear direction and theconsistency or regularity of its interior angles. By contrast, performance in generating word associations for figures appeared to be linguistically driven, with initial responses related to the similarity of shapes to letters of the alphabet. The norms and the computer program used to collect them can be downloaded from www.psychonomic.org/archive.

In a three-phase experiment with random shapes, participants (n = 94) first interactively determined if two equivalent shapes were rotated or reflected; second, memorized the shape; and third, determined if an imprint in a profile view of the ground was a rotated, reflected imprint of the shape, or an imprint not matching the original shape. Participants self-reported these strategies: Key feature, shape interaction, association/elaboration, holistic/perspective, divide and conquer, mental rotation/reflection and others. Participants reporting key features strategy were significantly more accurate on the computer-based visuospatial WM task. These results highlight the importance of strategy in visuospatial WM.

A student-centered stakeholder interaction model is presented to discuss the benefits of ePortfolio integration. We identified four constructs related to ePortfolios from a student perspective: employment, visibility, assessment, and learning. The instrument

The way students view and use ePortfolios are revealing elements to aid educators in the successful integration of ePortfolio systems. This research describes the development of the Electronic Portfolio Student Perspective Instrument (EPSPI) and initial validation (N=204) efforts in the context of an ePortfolio initiative in a College of Education. The EPSPI incorporates four domains from a student perspective: employment, visibility, assessment, and learning; and connects those domains with four relevant stakeholders: students, administrators, faculty, and employers. Descriptive analyses, exploratory factor analysis, and a qualitative analysis using grounded theory were used. Results indicate that student perspectives towards ePortfolios are multidimensional with three distinct, internally consistent underlying constructs: learning, assessment, and visibility. Qualitative analysis revealed four interrelated themes from a student perspective: system characteristics, support structure, purpose, and personal impact.

The experiment was a 4 Audio Speeds (1.0 = normal vs. 1.5 = moderate vs. 2.0 = fast vs. 2.5 = fastest rate) x Adjunct Image (Image Present vs. Image Absent) factorial design. Three-hundred five research participants were recruited from a public, southeastern university in the United States. Results showed statistically significant differences at 2.5 times the normal audio speed, in which performance on cued-recall and content recognition tasks was significantly lower than other audio speeds. Furthermore, representational adjunct images had a significant positive effect on cued-recall, but not content recognition. Participants in the normal audio speed and image present groups were significantly more satisfied than those in other treatments. Recommendations to various stakeholders are provided.

The current results document student achievement as a result of teacher inquiry, frequently observed conditions conducive to learning, and long-term impacts on ...
