This paper gives one explanation for the difficulties many students experience with certain stylized modeling tasks (solving algebra word problems) and puts these difficulties in the context of a theory about the acquisition of the concept of mathematical function. It also describes a visual programming language that can act as a bridge, and in some sense an alternative, to formal algebraic notation as a language for describing situations. Tracing the author's classroom experiments and his reflections on those experiments, the paper suggests a method for helping students.","PeriodicalId":334979,"journal":{"name":"Intell.

Textual machines are textual devices or engines in motion and they represent the cognitive processes that texts exhibit. Textual machines are revolutionary writing aids because once the kind of textual machine needed is visualized, it is easy to translate that insight into writing the text so that it accomplishes the same thing as the machine. The major part of this article describes and illustrates fourteen textual machines. The textual lens, for example, focuses directly on some information in a text and then expands and enlightens it. Some of the other textual machines presented in the article deal with more complicated processes, such as the selection and interpretation of information. The purpose of this article is to enable readers to gain awareness of their own cognitive processes by being able to visualize them through the various textual machines. This self-awareness results in a clearer analysis of t...","PeriodicalId":334979,"journal":{"name":"Intell.

This methodology can be formulated as a development lifecycle, ensuring that a uniform approach to courseware is taken. In a development group, there are complex interactions between group members. Without some formal organisation of the communication structures, development becomes non-uniform. Therefore, the roles of each team member must be clearly defined.","PeriodicalId":334979,"journal":{"name":"Intell.

From examination of current research and practice, illustrated by examples taken from case studies in commercial and academic collaborative courseware production, we highlight and discuss some of the common issues identified, notably quality assurance and re-use of course material. Appropriate re-use can dramatically increase the efficiency of the production of courseware and contribute to the maintenance of consistent standards. In terms of the quality of courseware, which is difficult to assess objectively other than by obtaining user / client feedback, we suggest that the degree of coordination of the skills and efforts of the courseware team is a significant factor affecting the quality of the courseware as well as the efficiency of production. A suitably designed model of coordination should permit quality assurance procedures to be integrated into actual courseware production.","PeriodicalId":334979,"journal":{"name":"Intell.

Client/server applications aim to provide an ideal desktop where users would submit a database query through a PC, unaware and unconcerned with the location and format of the data or the hosts needed to do the job. What is being described here is transparent, multi-vendor, distributed database access. In Educational Computing environments this would provide a working model of powerful, networked information systems where the database management system is implemented alongside easy, intuitive interfaces.","PeriodicalId":334979,"journal":{"name":"Intell.

The new model, called the Dexter-Groupware (DG) model, is an extension of the Dexter hypertext reference model and incorporates a conversion and interchange model (SGML-HyTime-Dexter model) that provides an interchange mechanism to support collaborative work. Based on the DG model, an open environment for CSCW and document re-use is proposed, and a prototype, the MUCH (Many Using and Creating Hypermedia) environment, is described. The MUCH system forms the centre of the environment and a set of import/export tools allows the MUCH system to interchange information with other systems by going through international standards.
