Exams should be valid, reliable, and discriminative. Multiple informative methods are used for exam analysis. Displaying analysis results numerically, however, may not be easily comprehended. Using graphical analysis tools could be better for the perception of analysis results. Two such methods were employed: standardized x-bar control charts with…

This study reports on the development, validation, and administration of a 48-item multiple-choice test to assess students' representational fluency of linear functions in a physics context (1D kinematics) and a mathematics context. The test includes three external representations: graphs, tables, and formulas, which result in six possible…

Most models of human performance on the traveling salesperson problem involve clustering of nodes, but few empirical studies have examined effects of clustering in the stimulus array. A recent exception varied degree of clustering and concluded that the more clustered a stimulus array, the easier a TSP is to solve (Dry, Preiss, & Wagemans,…

One of the major roles of a school psychologist is psychoeducational testing and the preparation of psychoeducational reports. Unfortunately, parents often have difficulty understanding psychoeducational reports. This difficulty might be ameliorated by supplementing psychoeducational reports with graphs. This hypothesis was tested with 144 parents…

The purpose of this study is to determine the extent of scale drift on a test that employs cut scores. It was essential to examine scale drift for this testing program because new forms in this testing program are often put on scale through a series of intermediate equatings (known as equating chains). This process may cause equating error to…

Provides examples in which graphs are used in the statements of problems or in their solutions as a means of testing understanding of mathematical concepts. Examples (appropriate for a beginning course in calculus and analytic geometry) include slopes of lines and curves, quadratic formula, properties of the definite integral, and others. (JN)

Describes studies designed to examine the instrumentation used to assess both graphing abilities and the impact of microcomputer-based laboratories (MBL) on students' graphing abilities. Results suggest that numerous disparities between the results of multiple-choice and free response instruments. The analysis also revealed that the impact of MBL…

This investigation evaluated performance of university students on visual and nonvisual versions of an achievement test. Two experimental designs assessed the effects and interactions between visual and nonvisual instructional modes, order of drawing test (before or after verbal/visual achievement test), and mode of drawing test (verbal cued or…

The major literature review by Black and Wiliam (1998a) provided strong research evidence indicating that assessment for learning can produce significant gains in students' learning. The present study applied the main aspects of assessment for learning, as highlighted in the Black and Wiliam review, in a specific area of science education, that of…

Investigates the real-time costs of sentence processing in early Spanish-English bilinguals. Bilinguals use an amalgam of monolingual strategies in choosing the agent of a sentence. The reaction time data reveal a larger language-specific component than the choice data. (37 references) (Author/CK)
