Developing domain ontologies for course content

Ontologies have the potential to play an important role in instructional design and the development of course content. They can be used to represent knowledge about content, supporting instructors in creating content or learners in accessing content in a knowledge-guided way. While ontologies exist for many subject domains, their quality and suitability for the educational context might be unclear. For numerous subjects, ontologies do not exist. We present a method for domain experts rather than ontology engineers to develop ontologies for use in the delivery of courseware content. We will focus in particular on relationship types that allow us to model rich domains adequately

Semantic modelling of learning objects and instruction

We introduce an ontology-based semantic modelling framework that addresses subject domain modelling, instruction modelling, and interoperability aspects in the development of complex reusable learning objects. Ontologies are knowledge representation frameworks, ideally suited to support knowledge-based modelling of these learning objects. We illustrate the benefits of semantic modelling for learning object assemblies within the context of standards such as SCORM Sequencing and Navigation and Learning Object Metadata

Learning from news: Is online better than print?

This study compares the process of learning from news between print and online news environments. The study adopts the framework of Cognitive Mediation Model that treats surveillance motivation as the cause of news orientation and news elaboration which in turn are the causes of knowledge acquisition.To identify the differences in news learning between print and online media, a “between-subjects” experiment was used. The study tested the two models using Structural Equation Modelling (SEM).The results show that both print and online models are supportive of the Cognitive Mediation Model. While most of the hypothesized relationships were supported, the study found that orientation in information space has significant effect on knowledge level of print but not online readers.This result suggests the disadvantages of Web non-linearity on learning outcome.The study also found that the mediating role of news orientation was only supported in the print model. The higher R2 value for print compared to online model suggests the influential role of traditional print in news learning

Using activity-oriented design methods (AODM) to investigatemobile learning

The past few years have witnessed significant interest and developments in researching mobile learning, with a lot of important contributions being made towards understanding and defining mobile learning. However, current research efforts are being redirected towards a new agenda to establish appropriate methods for investigating mobile learning, as this book testifies. This chapter contributes to this research effort by articulating how to adapt Activity-Oriented Design Methods (AODM – see Mwanza, 2002) for use in mobile learning research

Modelling dynamic decision making with the ACT-R cognitive architecture

This paper describes a model of dynamic decision making in the Dynamic Stocks and Flows (DSF) task, developed using the ACT-R cognitive architecture. This task is a simple simulation of a water tank in which the water level must be kept constant whilst the inflow and outflow changes at varying rates. The basic functions of the model are based around three steps. Firstly, the model predicts the water level in the next cycle by adding the current water level to the predicted net inflow of water. Secondly, based on this projection, the net outflow of the water is adjusted to bring the water level back to the target. Thirdly, the predicted net inflow of water is adjusted to improve its accuracy in the future. If the prediction has overestimated net inflow then it is reduced, if it has underestimated net inflow it is increased. The model was entered into a model comparison competition-the Dynamic Stocks and Flows Challenge-to model human performance on four conditions of the DSF task and then subject the model to testing on five unseen transfer conditions. The model reproduced the main features of the development data reasonably well but did not reproduce human performance well under the transfer conditions. This suggests that the principles underlying human performance across the different conditions differ considerably despite their apparent similarity. Further lessons for the future development of our model and model comparison challenges are considered

AODM as a framework and model for characterising learner experiences with technology

The task of characterising learner experiences with technology is increasingly becoming complex due to continuous technological advancements that enable learners to connect, collaborate, generate educational resources and promptly share them in various settings. The challenge for the educator is to understand how to effectively capture and represent learners’ current and future experiences with technology. This paper presents ‘Activity-Oriented Design Method’ (AODM) as a framework and model for characterising personalised and contextualised learner experiences with technology. The objective is to show how AODM can be used to understand learner experiences by examining learner practices with technology and interactions with each other. The aim is to assess the significance and adequacy of AODM as a framework and model that contributes to future understanding of learner experiences with technology. In order to support our arguments, we draw practical insights from two studies that applied AODM to e-learning investigations. The outcome of this analysis is an assessment of the capacity of AODM as a model and framework for characterising both current and future learner experiences with technology. Furthermore, the analysis illuminates the processes of change that inform the design and use of future technologies for learning
