Describes a system for building adaptive Computer Based Tests.

In this chapter the main roles played by representations in knowledge flows are analysed and the corresponding relevant properties of representation languages are identified (expressive power, focusing power, facilitating power and computability). Different types of languages and conceptual tools are taken into consideration and their properties ar...

Knowledge representations have a key role in knowledge management. The use of representations can facilitate knowledge flows by fostering the processes of making tacit knowledge explicit and of sharing explicit knowledge. The representation languages to be used in knowledge management should be reasonably easy to use, even for non-specialists, and...

This paper focuses on pedagogical plans intended as objects to support human communication. Its purpose is to describe a structural model for pedagogical plans which can assist both authors and users. The model helps authors to engage in the design of a plan as a communication project and helps users in the process of understanding, customizing, en...

In the knowledge society we must be able to deal with a new type of knowledge which is dynamic, distributed/globalized and complex. This change in the nature of knowledge imposes new requirements on educational systems, which must (i) provide individuals with new cognitive tools, and (ii) aim at harmonic integration between traditional learning pro...

Pilot actions for introducing ICT-based innovation in school education generally involve a multitude of elements and a range of different actors. Accounting for and grasping this complexity calls for systematic pedagogical planning efforts that provide a solid basis for accommodating the different perspectives, for analysing the factors at play and...

Con il 2003 Didamatica è arrivata alla sua sedicesima edizione. Dalla prima edizione (Milano 1985) sono cambiate davvero molte cose. La tecnologia innanzi tutto. Audiovisivi, informatica e telecomunicazioni, che erano all’epoca ambiti distinti con limitate possibilità di interazione, si sono integrati in una tecnologia sola e anche se il percorso n...

Il progetto ORA ha dunque scelto la rete telematica come strumento per rendere accessibili e divulgare i propri materiali. Questo il primo punto di contatto tra ORA e Tecnologie Didattiche (TD).

This paper refers to the ESM_BASE (Educational Systems Based on Multimedia Database) project carried out within the EEC DELTA programme. The concepts of ULM (Unit of Learning Mat.erial) and of DBLM (Database of multimedia Learning Material) as resources for learning and as bases for courseware reusability in the authoring process are discussed in c...

Computer Education is conceived as a process aimed at developing high level intellectual skills (problem solving, communication, independent learning, etc.) by an increasing number of people. In many cases this conception has been implemented by transferring models and methodologies originally belonging to the curricula of computer science speciali...

This paper describes the theoretical framework of a research project aimed at exploring the new potentialities for instructional systems offered by videodisc technology and artificial intelligence methodologies and techniques. In the context of this project, ‘Earth’, a prototype of ITS, is being developed, which embodies the ideas presented. In an...

This paper deals with the use of computers in the evaluation of learning with a special concern for diagnostic evaluation carried out with a formative aim. The described methodological framework for diagnostic evaluation is both oriented to produce highly individualized tests providing a detailed measure of students’ achievements and to minimize th...

Nel corso del lavoro è illustrata una esperienza di introduzione all'Informatica nella formazione di base. L'intervento, sviluppato nell'ambito del progetto IRIS in coordinazione con il Centro Europeo per l'Educazione, ha comportato lo sviluppo di una unità didattica orientata al primo biennio della scuola media superiore. L'esperienza viene illust...

A methodology for designing and implementing automatized diagnostic testing associated with remedial CAL sequences has been presented.This methodology is based on a hierarchical model of subject matter which provides ordered relationships among the various levels of student knowledge. The test handling strategy is designed to supply detailed inform...

This paper discusses a methodology for representing the subject matter for CAL dialogue. The methodology is based upon Petri Nets and is oriented to maximize the possibilities of control and individualization provided by CAL. Simple examples show how to build a content representation and how the same structure may be used as a common basis for diff...

The problem of portability of CAI material is discussed in connection with the structure of present and future CAI systems.

The problem of loop optimization for parallel processing is examined in this paper and a method is proposed to evidence the inherent parallelism in a FORTRAN-like loop. The method is based on the concept of interrupting tasks and imposes little restrictions on the loop structure. Parallelism is achieved by concurrent execution of the loop body for...

Existing models for deadlock detection and avoidance give practical solution only in the case of chains of independent tasks. In this paper we propose a non enumerative approach to deadlock avoidance when the workload consists of a graph-structured task system. The avoidance algorithm is based on an extention of the Coffman and Denning deadlock mod...

There are many cases in which the equivalence of two sequential machines must be tested. If machines actually exist, such a test can be effectively performed by means of I/O sequences of finite length; if machines are simulated, however, a different approach could be convenient. In this paper an equivalence test based on the algebraic manipulation...

COMES, a system for computer aided instruction oriented to programming languages, is described here. The system allows a full integration of theory learning and practical applications since it offers two different teaching strategies, one corresponding to a purely tutorial environment and one to a programming and problem-solving environment that ha...

ELLAS has characteristics which are fairly different from similar CAD systems due to the specific requirements of the didactic applications. In fact, sophisticated capabilities of analysis (sensitivity and transient response) and of interactive optimization have been overlooked, in order to keep the system simple and easy-to-use; besides, graphics...
