This article describes an integrated problem solving and program development environment, illustrating the application of the system with a detailed case study of a small-scale programming problem. The system, which is based on an explicit cognitive model, is intended to guide the novice programmer through the stages of problem solving and program…

Game-based learning has been a popular development and recommended as an effective pedagogy in educating new generations of learners. Few studies, however, have demonstrated the efficacy of game-based learning on learners' academic performance with empirical data. The described learning outcomes of game-based pedagogy within the limited available…

This dissertation provides an automated scoring method of speech fluency for second language learners of English (L2 learners) based that uses speech recognition technology. Non-standard pronunciation, frequent disfluencies, faulty grammar, and inappropriate lexical choices are crucial characteristics of L2 learners' speech. Due to the ease of…

Chemists have used computational science methodologies for a number of decades and their utility continues to be unabated. For this reason we developed an advanced lab in computational chemistry in which students gain understanding of general strengths and weaknesses of computation-based chemistry by working through a specific research problem.…

This paper presents a conceptual analysis of the technological dimensions related to the operationalization of CSCL macro-scripts. CSCL scripts are activity models that aim at enhancing the probability that knowledge generative interactions such as conflict resolution, explanation or mutual regulation occur during the collaboration process. We…

This work introduces the concept of an Object-Oriented Learning Object (OOLO) that is developed in a manner similar to the one that software objects are developed through Object-Oriented Software Engineering (OO SWE) techniques. In order to make the application of the OOLO feasible and efficient, an OOLO model needs to be developed based on…

We present COLLECT-UML, a constraint-based intelligent tutoring system (ITS) that teaches object-oriented analysis and design using Unified Modelling Language (UML). UML is easily the most popular object-oriented modelling technology in current practice. While teaching how to design UML class diagrams, COLLECT-UML also provides feedback on…

This paper investigates, through a case study, the development of a software architecture that is compatible with a system's high-level requirements. The case study is an example of an extended customer/supplier relationship (post-point of sale support) involved in e-universities and is representative of a class of enterprise without current…

Discusses the role of intelligent agents in facilitating the seeking and retrieval of information in Web-based library environments. Highlights include an overview of agents; current applications in library domains; an agent-based model for libraries; the design of interface agents; and implications for library policy and digital collections.…

Presents a layered architecture for hypermedia systems that uses the MHEG (Multimedia and Hypermedia Information Coding Expert Group) proposal to provide the desired independence between hypermedia applications' conceptual models and storage strategies for hypermedia objects. An overview of the MHEG standard proposal is provided. (Contains 16…

This study compared the effectiveness of self-, other-, and subjective-video models on teaching daily living skills to three individuals with developmental disabilities. Results indicated that all conditions were effective in promoting independent correct responding in both instructional and generalization settings and that the effects maintained…

Game-based learning is becoming popular in the academic discussion of Learning Technologies. However, even though the educational potential of games has been thoroughly discussed in the literature, the integration of the games into educational processes and how to efficiently deliver the games to the students are still open questions. This paper…

Preparation of tests and student's assessment by the instructor are time consuming. We address these two tasks in neuroanatomy education by employing a digital media application with a three-dimensional (3D), interactive, fully segmented, and labeled brain atlas. The anatomical and vascular models in the atlas are linked to "Terminologia…

StarLogo The Next Generation (TNG) enables secondary school students and teachers to model decentralized systems through agent-based programming. TNG's inclusion of a three-dimensional graphical environment provides the capacity to create games and simulation models with a first-person perspective. The authors theorize that student learning of…

Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information…
