4.1 The experimental result

One way to establish the speed of sound is to measure it experimentally. That is, one measures how long the sound takes to travel a known distance, and from this works out the speed. The answer turns out to depend somewhat on the prevailing temperature and humidity. At an air temperature of 14 °C the speed is 340 metres per second and at about 22.5 °C it is 345 metres per second. That is a change of speed of less than 1.5 per cent for an appreciable change of temperature. To a reasonable ap

1.1 Introduction

One of the most impressive but puzzling capacities we have is the ability to represent the world around us, both in talking about it among ourselves and in thinking about it as individuals. When someone utters the sentence, ‘The German economy is bouncing back’, for example, they are able to convey to their audience something about the German economy. Their utterance may be correct or it may be incorrect, but either way it is making a claim about how things are, and in this loose but intu

The Cognitive Transfer and the Tutor's Role in a CBL Environment
In this paper we report on a longitudinal study of a Leonardo da Vinci program regarding the application of a Computer Based Learning environment in three EU countries, Greece, Germany, and Holland. The `` Orestis''CD-ROM was a multimedia CBL environment aimed at teaching young offenders the basic and advanced skills for the use and maintenance of a photo-copy shop. The complete project consisted of three phases: construction of the CD-ROM, application of the instructional methodology in the par

Embedding Design Patterns in a Methodology for a Design Science of e-Learning
The discourse of research and practice in e-learning has been dominated by two extremes. On one hand, ethereal abstractions, which provide sound principles but do not lend themselves to implementation. On the other hand, detailed anecdotes which provide fascinating insights but pose a challenge to generalization. The void in between these two extremes calls for representations which capture transferable and modular elements of design knowledge. Design patterns originated as a form for democrati

Filmic Development of Architectural Animations
This paper proposes a general method to make animated presentations of architectural designs, based on cinematographic techniques. Particularly, it reviews theoretical documenttion about filmmaking as well as several productions that exhibit remarkable locations. The proposed method first comprises of a planning stage, with the narrative and graphic formulation of the presentation. Next is an elaboration or adjustment stage for the digital modelling of the design, and finally, there is an animat

Using visualizations to teach problem-solving skills in mathematics: Which kind of visualization wor
In the experiment described in this paper we investigated the effects of different kinds of computer-based visualizations on the acquisition of problem-solving skills in the domain of probability theory. Learners received either purely text-based worked examples, text plus an instruction to mentally imagine the examples’ contents, or they could retrieve either static pictures or concrete animations that depicted the problem statement and the problem states achieved by applying a specific solut

Balancing situativity and formality: the importance of relating a formal language to interactive gra
A situated cognition theory is presented in which situated learning is viewed from a Vygotskian perspective: the developmental situativity theory. It is assumed that learning is basically a non-symbolic inductive process that is greatly enhanced by formal systems which act as tools. Instruction should provide students with an environment containing elements to allow for situated activity as well as with appropriate formal tools.

Grid and Peer-to-Peer middleware for Cooperative Learning Environments
This paper presents the work done by the research group of the Open University of Catalonia within the coordinated project towards the definition of adequate grid and peer-to-peer middleware for cooperative learning environments. The main results of our research consist in designing a layered framework for modelling online collaborative learning interactions which in turns leads to the development of a computational platform, called Collaborative Learning Purpose Library (CLPL), that can be used

Cyberinfrastructure for Education and Learning for the Future: a vision and research agenda
This report is the result of a series of workshops organized by the Computing Research Association and the International Society of the Learning Sciences with support from the National Science Foundation (Grant No. REC-0449247). The purpose of the workshop series was to explore where we are in the application of pervasive computing power to education, and where we need to be. In particular, the intent was to develop a map of where NSF can strategically place its resources in creating the learni
