The technology of automated short answer grading (ASAG) can efficiently process answers according to human-prepared grading examples. Computer-assisted acquisition of grading examples uses a computer algorithm to sample real student responses for potentially good examples. The process is critical for optimizing the grading accuracy of machine…

Mathematical modelling is acknowledged to be one of the major dimensions of mathematical competence, and well-designed modelling activities can provide students with the opportunity to use mathematical concepts and procedures in a meaningful way. Additionally, modelling activities are regarded as suitable contexts for enabling students to use…

While learning can happen anywhere and everywhere, most educational practices in K-12 are confined within the walls of a classroom and the school; such practices narrowly define learning and exclude the opportunities that an expanded and digitally mediated definition of learning can offer. Augmented reality (AR) technologies offer exciting new…

Curricula authoring is a complex process, involving different actors and different kinds of knowledge. Learners aim at acquiring expertise about some topic of their own interest, and need to perceive that the curriculum they attend will lead them toward their goal; when this does not happen, they become demotivated. Learners are all different, not…

This article describes an implementation of interactive virtual environments that have been designed for supporting the education of technical skills in material processing technology. The developed web-based systems provide the capability to train students in the technical skills of material processing technology without the need to work on…

Recent applications of technology to mathematics education have been designed with cognitive and constructivist theoretical perspectives in mind, viewing mathematical learning as the acquisition of knowledge through the construction of meanings and connections between concepts. With the advent of increasingly flexible communication technologies,…

In this paper behavior during the teaching-learning process is modeled by means of a fuzzy cognitive map. The elements used to model such behavior are part of a generic didactic model, which emphasizes the use of cognitive and operative strategies as part of the student-tutor interaction. Examples of possible initial scenarios for the…

Formal mathematical methods remain, for most high school students, mysterious, artificial and not a part of their regular intuitive thinking. The authors develop some themes that could lead to a radically new approach. According to this thesis, the teaching of programming languages as a regular part of academic progress can contribute effectively…

Digital learning environments are generally composed of resources that cumulatively meet some specified educational objective, with each resource facilitating the acquisition of a subset of the concepts to be learned. In such contexts narrative has, for example, been used to support the understanding and navigation of a course or curriculum…

The Boxer Project conducted the research that led to the synthetic review "Issues in Component Computing." This brief essay provides a platform from which to develop our general perspective on educational computing and how it relates to components. The two most important lines of our thinking are (1) the goal to open technology's creative…

This paper provides a review of the rhetoric behind the component movement in educational software, and a critical analysis and synthesis of issues underlying the movement. We draw on case studies of several significant recent component projects in order to assess claims and to uncover and examine issues that are less often considered. While our…

Describes three projects at Carnegie Mellon University (Pennsylvania) that developed novice programming environments based on structure editors: GNOME, MacGNOME and ACSE (Advanced Computing for Science Education). Tracks the evolution of the programming environments and courses, documenting important lessons and discoveries about novice…

The paper discusses three aspects central to the 10 year-old process of design, development and use of E-slate, a construction kit for educational software. These are: (1) the design of computational media for user empowerment, (2) the socially-grounded approach to the building of user communities and (3) the issue of long-term sustainability as…

In this article, an extension of the existing structure of learning objects is described. The solution addresses the problem of the access and discovery of educational resources in the distributed Internet environment. An overview of e-learning standards, reference models, and problems with educational resources delivery is presented. The paper…

A considerable amount of the effort and enthusiasm that goes into the development and implementation of technology-mediated learning environments often fails to create effective settings for learning. Too often the opportunities and advantages of the use of technology in the learning process are poorly exploited. This paper explores ways in which…
