In Computer Supported Collaborative Learning (CSCL), one of the most important tasks for instructional designers is to define scenarios that foster group learning. Such scenarios, defined as Units of Learning (UoLs), comprise different components and are organized according to pedagogical approaches to orchestrate group learning processes. Examples of UoL components are learning objects, studen...

Optimization software is commonly used to solve simulation-based problems such as optimal design and control, model parameter estimation, and best/worst-case scenario identification. While the value of such software is widely recognized, user feedback indicates that these tools are difficult for nonexperts to use. In particular, users are unfamiliar with the details of the plethora of available...

This paper assumes each user has more than one queue, derives a new packet-dependant proportional fairness power allocation pattern based on the sum of weight capacity and the packet’s priority in users’ queues, and proposes 4 new cross-layer packet-dependant OFDM scheduling schemes based on proportional fairness for heterogeneous classes of traffic. Scenario 1, scenario 2 and scenario 3 lead r...

In this paper, we suggest that case-based resources, which are used for assisting cognition during problem solving, can be structured around the work of narratives in social cultural psychology. Theories and other research methods have proposed structures within narratives and stories which may be useful to the design of case-based resources. Moreover, embedded within cases are stories which ar...

The aim of this article is to discuss possible user scenarios for " intelligent " Learning Management Systems (iLMS) and challenges for implementing them. We focus on those scenarios in which Machine Learning (ML) can be used to enhance general purpose web-based Learning Management Systems. We will propose a software engineering framework for the design and implementation of an iLMS.
