This experimental investigation considers how the inherent conceptual structure of external representations influences individuals' knowledge structure, and in addition proposes a measure of global collective knowledge to account for the influence of pre-existing knowledge structure. In two studies, undergraduates in a hospitality management…

This experimental study examined the effects of conceptual change-oriented refutation text (RT) on declarative knowledge and conceptual knowledge. Information Science undergraduates (N = 66) enrolled in two sections of a course with different instructors but the same syllabus were randomly assigned to one of four RT treatments that included read…

This experimental investigation replicates previous investigations of the effects of left margin screen background color hue to signal lesson sections on declarative knowledge and extends those investigations by adding a measure of structural knowledge. Participants (N = 80) were randomly assigned to receive 1 of 4 computer-based lesson treatments…

In this descriptive investigation, we seek to confirm and extend a technique for automatically scoring concept maps. Sixty unscored concept maps from a published dissertation were scored using a computer-based technique adapted from Schvaneveldt (1990) and colleague's Pathfinder network approach. The scores were based on link lines drawn between…

This investigation considers the instructional effects of color as an over-arching context variable when learning from computer displays. The purpose of this investigation is to examine the posttest retrieval effects of color as a local, extra-item non-verbal lesson context variable for constructed-response versus multiple-choice posttest…
