Cognitive efficiency (CE) is generally defined as qualitative increases in knowledge gained in relation to the time and effort invested in knowledge acquisition. Across disciplines, limited consensus exists concerning the conceptual and measurement properties of CE partly because some researchers indiscriminately use the construct of CE to…

A central goal of the learning sciences is to discover principles that determine the optimal amount of instructional assistance to support robust learning (Koedinger & Aleven, 2007). We examined learning outcomes from providing and withholding stepwise instructional explanations as students studied worked examples and solved physics problems. We…

Students are frequently presented with novel visualizations introducing scientific concepts and processes normally unobservable to the naked eye. Despite being unfamiliar, students are expected to understand and employ the visualizations to solve problems. Domain experts exhibit more competency than novices when using complex visualizations, but…

Whereas product-oriented worked examples only present a problem solution, process-oriented worked examples additionally explain the rationale behind the presented solution. Given the importance of understanding this rationale for attaining transfer, process-oriented worked examples would be expected to result in more efficient transfer. However, a…

This article investigates the effect of the vitality of historical issues in collective memory on students' history learning processes and products. Forty 12th grade students of different ethnic background participated in two historical problem-solving learning tasks. The historical issues were found to differ in their vitality in collective…

In two experiments we explored how learning from traditional molar worked-out examples--focusing on problem categories and their associated overall solution procedures--as well as from more efficient modular worked-out examples--where intrinsic cognitive load is reduced by breaking down complex solutions into smaller meaningful solution…

A new computerized environment introducing a variety of metacognitive support mechanisms (MSMs) in different phases of the problem-solving process was designed to influence students' transfer from solving structured problems (near transfer) to solving open-ended problems (far transfer). Two hundred and thirty one students (aged 13-14 years) were…

Whole tasks for acquiring complex skills are often too difficult for novices. To solve this problem, "process support" divides the problem solving into phases, offers driving questions, and provides feedback. A multimedia program was used to teach sophomore law students ("N"=82) to prepare and carry out a plea. In a randomised 2x2 design with the…

Traditional assessment methods are not always suitable for diagnosing learners' knowledge structures at different levels of their expertise. This paper describes an alternative schema-based rapid assessment technique and its application in the area of arithmetic word problem solving. The technique is based on an assessment of the extent to which…
