This paper describes LOGAX, an interactive tutoring tool that gives hints and feedback to a student who stepwise constructs a Hilbert-style axiomatic proof in propositional logic. LOGAX generates proofs to calculate hints and feedback. We compare these generated proofs with expert proofs and student solutions, and conclude that the quality of the…

Intelligent tutoring systems (ITSs) aim to deliver personalized learning support to each learner, aligning with the educational aspiration of many countries, including China. ITSs' personalized support is mainly achieved by providing individual prompts to learners when they encounter difficulties in problem-solving. The guiding principles and…

A central factor in research guided by the Cognitive Load Theory (CLT) is the mental effort people invest in performing a task. Mental effort is commonly assessed by asking people to report their effort throughout performing, learning, or problem-solving tasks. Although this measurement is considered reliable and valid in CLT research,…

Purpose: The purpose of this paper is to develop a set of generic prompting principles and a framework of prompts that have the potential to foster learning and skill acquisition among adult novices when performing complex, ill-structured problems. Design/methodology/approach: Relevant research in the literatures surrounding problem structure,…

Tutoring systems provide students with various types of on-demand and context-sensitive hints. Students are required to consciously adapt their help-seeking behavior, proactively seek help in some situations, and solve problems independently without supports in other situations. We define the latter behavior as stoic behavior in hint seeking. In…

Alzheimer's disease (AD) can impair metacognition in addition to more basic cognitive functions like memory. However, while global metacognitive inaccuracies are well documented (i.e., low deficit awareness, or anosognosia), the evidence is mixed regarding the effects of AD on local or task-based metacognitive judgments. Here we investigated local…

Despite frequent reports of academic success, individuals with high functioning autism or Aspergers Syndrome (HFA/AS) often manifest deficits in social abilities. These deficits can lead to daily difficulties, and negative long-term outcomes. Deficits in social competency are evident in this population from an early age, as children with HFA/AS…

A meta-analytic review of empirical studies that have investigated incubation effects on problem solving is reported. Although some researchers have reported increased solution rates after an incubation period (i.e., a period of time in which a problem is set aside prior to further attempts to solve), others have failed to find effects. The…

This study examined how web-based integration and procedure question prompts differentially affected students' knowledge acquisition and ill-structured problem solving skills, particularly in representing problem(s), developing solutions, and monitoring and evaluating a plan of action within the social science context. Eighty-four undergraduate…

This study examined the effects of question prompts, knowledge integration prompts, and problem solving prompts, embedded in a Web-based learning environment in scaffolding preservice teachers' conceptual understanding and problem solving in an ill-structured domain. A mixed-method study was employed to investigate the outcomes of students'…

A problem-solving strategy to prevent work injuries, involving temporary use of cue cards, was successfully taught in a supported employment setting to nine adults with mild to moderate mental retardation. Interviews and staged generalization assessments before and after the 12-week training indicated trainees generalized their new problem-solving…

Educational assessment, as it is typically conducted in U.S. schools, does not successfully capture or build on potentially important content knowledge and understanding of Indigenous students. In fact, current policies (such as the No Child Left Behind Act, 2002) are interfering with the implementation of many of the things we know about making…

The purpose of this study was to describe how one primary teacher of poor and working class rural students promoted small-group dialogue about books and literary concepts. Specifically, we focused on how she guided the students from the beginning of a lesson in ways that later led to dialogue during a videotaped four-day lesson sequence. We…
