While many studies have demonstrated that conversational tutoring systems have a positive effect on learning, the amount of manual effort required to author, design, and tune dialogue behaviors remains a major barrier to widespread deployment and adoption of these systems. Such dialogue systems must not only understand student speech, but must…

The project of ubiquitous computing aims to embed computation into everyday spaces. As a practice that is heavily concerned with space and place, its stance towards mobility is sometimes conflicted--treating mobility by turns as a disruption or as an opportunity--and almost always conceiving of it as free and empowered. Conducted in industrial and…

This paper presents an agent-based educational environment to teach argument analysis (ALES). The idea is based on the Argumentation Interchange Format Ontology (AIF)using "Walton Theory". ALES uses different mining techniques to manage a highly structured arguments repertoire. This repertoire was designed, developed and implemented by us. Our aim…

The informatics moment is the moment when a person seeks help in using some digital technology that is new to him or her. This article examines the informatics moment in people's everyday lives as they sought help at a branch public library. Four types of literacy were involved: basic literacy (reading and writing), computer literacy (use of a…

This article distills a discussion about the goals, mechanisms, and effects of three environments which aim to support the acquisition and development of computing concepts (problem solving and programming) in pre-University and non-technical students: Alice, Greenfoot, and Scratch. The conversation started in a special session on the topic at the…

The current study aimed to reveal elementary school students' perceptions of technology through their pictorial representations and their written expressions based on their pictorial representations. Content analysis based on the qualitative research method along with art-based inquiry was applied. The "coding system for the concepts revealed…

This paper presents the requirements work carried out as part of developing an intervention to improve students' critical thinking skills using location-based mobile learning. The research emerged from seeking to identify ways of getting Interaction Design students into real world environments, similar to those in which they will eventually be…

This article presents a reading of the user interface in one public library system. Its aim is to find out the frames and competences required and used in the communication between the computer and the patron. The authors see the computer as a text that is to be read by the user who wants to search for information from the library. The transition…

Information security threats to educational institutions and their data assets have worsened significantly over the past few years. The rich data stores of institutional research are especially vulnerable, and threats from security breaches represent no small risk. New genres of threat require new kinds of controls if the institution is to prevent…

This paper presents low-cost experiments for a control systems laboratory module that is worth one and a third credits. The experiments are organized around the microcontroller-based control of a permanent magnet dc motor. The experimental setups were built in-house. Except for the operating system, the software used is primarily freeware or free…

The development of telerobotic systems has evolved from Single Operator Single Robot (SOSR) systems to Multiple Operator Multiple Robot (MOMR) systems. The relationship between human operators and robots follows the master-slave control architecture and the requests for controlling robot actuation are completely generated by human operators. …

Purpose: Competition for resources appears to be increasing at a time of political, security (including energy, food and climate) and economic change; leading to potential collapse. The purpose of this conceptual paper is to examine the impact of policies exercised at the macro level on methods and processes applied at the micro level through, for…

HCI is a field which has an increasing popularity by virtue of the spread of the computers and internet and gradually contributes to the production of the user-friendlier software and hardware with the contribution of the scientists from different disciplines. Teacher candidates studying at the computer and instructional technologies department…

Remote learning has been an increasingly growing field in the last two decades. The Internet development, as well as the increase in PC's capabilities and bandwidth capacity, has made remote learning through the internet a convenient learning preference, leading to a variety of new interfaces and methods. In this work, we consider a remote…

Organizing refers to methods of distributing physical and symbolic tasks among multiple agents in order to achieve goals. My dissertation investigates the dynamics of organizing in hybrid information processing systems that incorporate both humans and computers. To explain the behavior of these hybrid systems, I develop and partially test a theory…
