The cognitive load imposed by instruction is an important consideration for instructional designers. Theoretical models have traditionally divided total cognitive load into intrinsic, extrinsic, and germane load. The 10-item Cognitive Load Inventory (CLI-10) is designed to measure these three types of cognitive load. It is typically administered…

This study investigated the performance of four widely used data-collection designs in detecting test-mode effects (i.e., computer-based versus paper-based testing). The experimental conditions included four data-collection designs, two test-administration modes, and the availability of an anchor assessment. The test-level and item-level results…

Relational reasoning is the foundational cognitive ability to discern meaningful patterns within an informational stream, but its reliable and valid measurement remains problematic. In this investigation, the measurement of relational reasoning unfolded in three stages. Stage 1 entailed the establishment of a research-based conceptualization of…

A comparison of double as opposed to single multiple-choice questions yielded significant differences in regard to item difficulty, item discrimination, and internal reliability, but not concurrent validity. (Author/PN)

The effects of violating four item construction principles were examined to assess the validity of the principles and the importance of students' test wiseness. While flawed items were significantly less difficult than sound items, differences in item discrimination, test reliability, and concurrent validity were not observed. (Author/BW)

Characteristics of 11 Repgrid indices of cognitive structure, particularly Smith and Leach's hierarchical complexity index, are investigated among boys and girls, aged 9-15. The Smith & Leach index is shown to be significantly reliable; but in common with seven indices of cognitive differentiation, it is of dubious validity. (Author/GDC)
