The nature of computer based learning and instructional environments that support it have changed dramatically in the last decade. The growth of hypertext, hypermedia and multimedia provided the capabilities necessary for developing complex learning environments. The system described in this paper is being developed to be used in Personal Computer workstations with multimedia and network capabi...

— In the current context of standard development strategies, the use of existing standards has been combined with the creation of ad-hoc formal specifications and tools. In this production framework, educational institutions must rethink the content life cycle towards a sustainable model based on a combination of its own research and use of existing standards. This makes it possible to integrat...

This paper focuses on how notions of inference can be fostered in middle school through the use of carefully designed tasks, open-ended software simulation tools, and social activity that focuses on making data-based arguments. We analyzed interactions between two sixth-grade students who used software tools to formulate and evaluate inferences during a 12-day instructional program that utilize...

Over the last ten years, computer educational games are increasing as popular instructional tools. This paper defines a machine-processable data structure to represent “challenge” in computer educational games such a structure supports estimates of a player’s capability and of the level of challenge, allowing the automatic provision of a suitable activity at an appropriate challenge to the play...

Development of interactive e-learning courseware has focused largely on the instructional design approach of multimedia applications and has brought about a substantial amount of success in producing engaging multimedia educational resources. In this article I explore how the multimedia instructional strategies and processes can be enhanced by incorporating the principles of cognitive psycholog...

Two research communities that need to work closer together are the community looking into the depiction or representation of learning designs and the community focusing on IMS Learning Design and its increased accessibility. A synopsis of some findings within these communities is given in order to then evaluate a graphical IMS Learning Design editor, the Graphical Learning Modeller. 1. Learning...

When do high-tech environments promote learning? The goal of this article is to offer one answer to this question by examining the classic distinction between media and method, in terms of their roles in promoting learning with technology. To this end, I first propose a cognitive theory of learning with media, from which a set of instructional design principles are derived. Then I review resear...

This paper develops Aristotle’s idea of phronesis, or practical wisdom, as a framework to access, represent and communicate the complexity of successful instructional leadership practice in schools. The design and use of artifacts, the tools leaders develop and implement in their practice, provide a window into the patterns of problem-setting and problem-solving that guide the expression of phr...

We develop the core of a method for solving the data archive and curation problem that confronts the custodians of restricted-access research data and the scientific users of such data. Our solution recognizes the dual protections afforded by physical security and access limitation protocols. It is based on extensible tools and can be easily incorporated into existing instructional materials.

the aim of the present study was to investigate the effect of different methods of self-talk (motivational, instructional, and combined) on acquisition and learning of a motor perceptional task (dart) and physical efficacy in female students aged between 13 and 18. 48 female students (mean age 15.46 yr) who were novice at dart throwing voluntarily participated in this study. participants were d...
