Intelligent Tutoring Systems (ITS) assist students in learning by adaptively providing pedagogical assistance. Numerous empirical studies have shown that students learn more effectively by interacting with ITSs in comparison to traditional classroom based teaching [1, 2]. Although ITSs are highly regarded as effective tools for education, developing an ITS is a time and labour intensive task re...

BACKGROUND E-learning and blended learning approaches gain more and more popularity in emergency medicine curricula. So far, little data is available on the impact of such approaches on procedural learning and skill acquisition and their comparison with traditional approaches. OBJECTIVE This study investigated the impact of a blended learning approach, including Web-based virtual patients (VP...

Acquiring the domain knowledge is a task that requires a major portion of the time and effort when building an ITS. Researchers have been exploring ways of automating the knowledge acquisition process since the inception of ITSs with limited success. All past research attempts have focussed on acquiring knowledge for procedural domains. Our goal is to develop an authoring system that acquires k...

The objective of the present study was to evaluate patterns of implicit processing in a task where the acquisition of explicit and implicit knowledge occurs simultaneously. The number reduction task (NRT) was used as having two levels of organization, overt and covert, where the covert level of processing is associated with implicit associative and implicit procedural learning. One aim was to c...

Although computational models developed in cognitive architectures are often rich in their knowledge of procedural skills, they are often poor in their knowledge of declarative facts about the world. This work endows the ACT-R cognitive architecture with world knowledge derived from Wikipedia, compiling a knowledge base of over 37 million declarative facts that can be accessed by a cognitive mo...

The aim of this article is to understand permanence and changes inside organizational routines. For this purpose, it seems important to explain how individual and collective memorisation occurs, so as to grasp how knowledge can be converted into routines. Although memorisation mechanisms imply a degree of durability, our procedural and declarative knowledge, and our memorisation processes, evol...

Enterprise systems (ESs) are customizable, integrated software applications designed to support core business processes. This paper reports research contrasting the relative effectiveness of two strategies for ES end-user training that differentially reflect the Sein, Bostrom, and Olfman (1999) hierarchical knowledge-level model. One strategy— procedural—involves training that targets the three...

Due to the importance of training, many scientists have studied effective training schedules, and they have compared distributed practice schedules to massed practice schedules. Most of the results consistently show that a distributed practice schedule outperforms a massed practice schedule in a retention test, because of the spacing effect in human memory. This result may lead new scientists w...

There have been several attempts to automate knowledge acquisition for ITSs that teach procedural tasks. The goal of our project is to automate the acquisition of domain models for constraint-based tutors for both procedural and non-procedural tasks. We propose a three-phase approach: building a domain ontology, acquiring syntactic constraints directly from the ontology, and engaging the author...
