In this research we are aiming at supporting complex instructional design (ID) process for CSCL environment. To fulfill the aim we have been constructing an ontology to represent computer supported collaborative learning (CSCL) session. The ontology will work as both vocabulary to describe the session and design pattern referred to during the instructional design process. In this paper, we desc...

This paper describes work in progress on the development of a social timeline that aims to enrich feedback for people learning music within an online community. This interface is novel because it uses multiple layers for group discussions rather than the single layer found in websites such as SoundCloud. Multilayered timelines are commonly used for audio and video editing, but have not been use...

Object-oriented software architectures, such as design patterns and frameworks, have found extensive use in software industry. As a design technique, these architectural structures have proven themselves very valuable. Their implementation in traditional object-oriented programming languages, however, is often difficult, since these languages provide no support for the explicit specification of...

Automatically creating images that give a sense of content can be useful in a number of settings. Such images can summarize a larger collection of media in novel ways, giving an evocation of the whole, rather than a precise linguistic summary. Paradoxically, such visual summaries are often found to be more useful as indicators of the gestalt of a media than more traditional language summaries. ...

We propose a research plan to further the understanding of design pattern evolution. Current research into design pattern evolution focuses on the structural elements of decay, which is realized as structural grime. We plan to expand the current state of research by introducing the notion of behavioral grime, or unwanted artifacts that appear at run-time in a pattern. This form of grime may be ...

In this paper we show the Casanova language (and its accompanying design pattern, Rule-Script-Draw) in action by building a series of games with it. In particular we discuss how Casanova is suitable for making games regardless of their genre: the Game of Life, a shooter game, an adventure game and a strategy game. We also discuss the difference between Casanova and existing frameworks.

Video summaries are becoming increasingly popular as a way to convert large chunks of video into smaller, more comprehensible units. Many video summarization techniques rely on finding features in the video or audio streams, using them to identify clips, and then assembling the most salient clips into a shorter version of the original. An alternative approach is to match take advantage of the k...

This paper reports on a design experiment in the domain of number sequences conducted in the course of the WebLabs project. We iteratively designed and tested a set of activities and tools in which 10-14 year old students used the ToonTalk programming environment to construct models of sequences and series, and then shared their models and their observations about them utilising a webbased coll...

Most current object-oriented design techniques and approaches focus on the new development of a software system, without regarding the reorganization of existing systems at all. But many people point out, that after the initial design and implementation of an object-oriented system, the system must often be reorganized in order to get a cleaner design which is easier to understand, modify and e...

the author in this research has tried to link the alexander pattern language theory, which is based on human oriented and spatial factors, to landscape design, which could come to a cyclic model of “a pattern language for landscape design” in iranian schools of architecture. so, a landscape design process based on the value of human-oriented approach, which is extracted from other values, and t...
