Collaborative problem solving (CPS) is a crucial 21st century skill; however, current technologies fall short of effectively supporting CPS processes, especially for remote, computer-enabled interactions. In order to develop next-generation computer-supported collaborative systems that enhance CPS processes and outcomes by monitoring and…

This paper characterized the extent of collaboration of pairs of novice programmers as they traced and debugged fragments of code using cross-recurrence quantification analysis (CRQA). This was a preliminary analysis that specifically aimed to compare and assess the collaboration of pairs consisting of two individuals who may have different or…

Instructors have to make important decisions regarding the type of assessment that will finally be implemented when producing online learning materials, since this has a noticeable effect in terms of the methodology, the approach, and the attitude of all the actors involved (Goertler, 2011). This study investigates students' perception of tutor…

This paper describes Clilstore and how this tool can support Content and Language Integrated Learning (CLIL), which involves teaching a curricular subject through the medium of a foreign language, as was evidenced through data collected from two surveys conducted with secondary school teachers from various European countries. [For full…

The present paper aims to review two motivations to conduct "what if" analyses using Excel and "R" to understand the statistical significance tests through the sample size context. "What if" analyses can be used to teach students what statistical significance tests really do and in applied research either prospectively to estimate what sample size…

This paper reports on the ongoing international project "System architecture for ICALL" and the progress made by the Swedish partner. The Swedish team is developing a web-based exercise generator reusing available annotated corpora and lexical resources. Apart from the technical issues like implementation of the user interface and the…

The current development of educational applications for language learning has experienced a qualitative change in the criteria of interaction between users and devices due to the technological advances of input and output data through keyboard, mouse, stylus, tactile screen, etc. The multiple interactions generated in a natural way by humans…

This paper describes a multimedia authoring system called MOPed-II. Like other authoring systems, MOPed-II reduces the time and expense of producing end-user applications by eliminating much of the programming effort they require. However, MOPed-II reflects an approach to authoring tools for educational multimedia which is different from most…

Many students find climate classification laborious and time-consuming, and through their lack of repetition fail to grasp the details of classification. This paper describes an expert system for climate classification that is being developed at Middle Tennessee State University. Topics include: (1) an introduction to the nature of classification,…

This paper discusses a computerized learning environment called TurtleGraph that is designed and developed to support collaborative problem solving. Within the learning environment, learners are requested to write computer programs to generate geometric figures. The instructional focus of the system is to enhance the learner's List Processor…

Computer programming is a domain of knowledge that is generally considered difficult by students, many of whom experience low levels of achievement and become disillusioned. This paper suggests that cognitive load theory needs to be taken into account when designing instructional materials for this domain. The cognitive load that is experienced by…

This article describes the purpose, development, and implementation of a cognitive-based instructional intervention and its impact on learning motivation. The study was conducted in a programming-based problemsolving course for first-year engineering students. The results suggest that the instructional intervention developed based on the…

The importance of the Extensible Markup Language (XML) technology family in the field of Computer Assisted Learning (CAL) can not be denied. The Instructional Management Systems Project (IMS), for example, provides a learning resource XML binding specification. Considering this specification and other implementations using XML to represent…

This paper describes a National Science Foundation-sponsored project at Louisiana Technological University to develop computer-based laboratories for "hands-on" introductions to major topics of computer science. The underlying strategy is to develop structured laboratory environments that present abstract concepts through the use of…

Experience has shown that the production of rich-media content for Web-based courses tends to be extremely cost- and time-consuming. One way for campus-based universities to reduce authoring costs is to automate the production process by using suitable tools for capturing live lectures. This paper describes different technical approaches to…
