Connecting theoretical frameworks: the telma perspective
In this text, we report on a research project developed within the European research team TELMA (Technology Enhanced Learning in MAthematics) of the Kaleidoscope network of excellence created in 2004. We describe the conceptual and methodological tools we have progressively built for allowing productive research collaboration and overcoming the difficulties resulting from the diversity and heterogeneity of our respective theoretical backgrounds. We also show how these tools have contributed to g

Investigation of Q-Learning in the Context of a Virtual Learning Environment
We investigate the possibility to apply a known machine learning algorithm of Q-learning in the domain of a Virtual Learning Environment (VLE). It is important in this problem domain to have algorithms that learn their optimal values in a rather short time expressed in terms of the iteration number. The problem domain is a VLE in which an agent plays a role of the teacher. With time it moves to different states and makes decisions which regarding action to choose for moving from current state to

Identifying Coordination Agents for Collaborative Telelearning
This paper deals with identifying roles for coordination agents in a future collaborative telelearning environment. The current practice of students participating in a net-based simulation marketing game on-campus, is studied with an eye on designing a future collaborative telelearning environment where this same net-based simulation game will be central. The work described in this paper is situated within the theoretical foundations of computer supported collaborative learning (CSCL). In partic

A Framework System for Intelligent Support in Open Distributed Learning Environments
Recent trends in the design of learning support systems are characterized by considering group interaction, by combining intelligent support with interactive learning environments, by providing reusable domain-independent components, and by using agent-structured architectures. Taking these trends into account, an open framework system has been developed for integrating distributed intelligent support components with an interactive and collaborative learning environment.

Stagecast Creator™ and Webct™: An integrated use of computer programming and a virtual learning en
This paper reports on an effort to use Stagecast Creator™ as a means for developing modelling skills among undergraduate students taking an introductory course in science that took place in a virtual learning environment (WebCT™). An inquiry-based curriculum was implemented, which guided students working in small groups to collect and study moon observations and construct a series of successive models of the moon phases using Stagecast Creator™.

Web 2.0 for Content for Learning and Teaching in Higher Education
The study will provide a set of recommendations for the JISC, institutions, and teachers on the effective use of Web 2.0 technologies for sharing content for teaching and learning. This will be achieved by desk research building on JISC funded and other work already undertaken, and widespread consultation across the community through an online workshop. The desk research will look at both existing practice and institutional policies which can facilitate or inhibit the use of Web 2.0 technologie

Didactic Decision-Making Process In a Surgery Learning Environment
In this paper we present our model of the didactic decision-making process and our method to define the apprenticeship utility function. This model is embedded in a computer-based learning environment dedicated to orthopedic surgery. The decision model allows the production of feedback relevant to the user’s knowledge during her/his activities with the learning environment. The surgical knowledge in the learning environment is represented with Bayesian Networks and the decision-making process

Organizational scenarios for the use of learning objects
The Dutch six-part series Leerobjecten in de praktijk (Learning objects in practice) is about six divergent and difficult problems that occur frequently in working with learning objects. Based on research into existing practice, guidelines are offered to policy makers, educational technology consultants, teachers, educational designers and developers of digital learning materials who are struggling with these problems in higher education. Organizational scenarios presents the following three s

A modelling challenge : untangling learner knowledge
For now about three decades, systematic research on students learning of science and mathematics has evidenced a great variety of the possible understanding for a given notion, as well as an important sensitivity of these understandings to contexts. Students' knowing appears as a tangle of local conceptions of which we have a very partial and unorganised picture. We present here the outlines of the modelling tool we have developed, and of its framework, in order to give account of learners' know

Computational Representation of Collaborative Learning Flow Patterns Using IMS Learning Desing
The identification and integration of reusable and customizable CSCL (Computer Supported Collaborative Learning) may benefit from the capture of best practices in collaborative learning structuring. The authors have proposed CLFPs (Collaborative Learning Flow Patterns) as a way of collecting these best practices. To facilitate the process of CLFPs by software systems, the paper proposes to specify these patterns using IMS Learning Design (IMS-LD). Thus, teachers without technical knowledge can p

1.1 Examples
Learning how to learn: a process we all engage in throughout our lives, but no single method of learning guarantees success. This unit aims to make the process of learning much more explicit by inviting you to apply various ideas and activities to your own study as a way of increasing your awareness of your own learning. Most learning has to be an active process – and this is particularly true of learning how to learn.

4.3 Chain growth polymerization

Chain growth polymerization is basically a three-stage process, involving initiation of active molecules, their propagation and termination of the active chain ends.

4.1 Understanding the polymerization process

Converting monomer to long chain polymer is the final step in the polymer manufacturing sequence. Polymerization is usually highly favourable in thermodynamic terms, mainly on energetic grounds because ordering molecules into linked chains is a process where the entropy is decreased. Heat is always given out during polymerization owing to the very favourable energetics of reaction, a point you may have noticed if you have ever made GRP parts for your car, for example!

5.6.3 Conformation and crystallinity

If there are key connections between the chain configuration and crystallisation, you might also expect some more subtle effects from rotation about chain bonds. After all, polymer chains must be able to twist into the regular conformation demanded for crystal structures (Figure 57(a)). And what influence will rotation have on the precise conformation adopted by the chain?

7 Summary

Polymers are long chain molecules with properties dominated by their chain behaviour and the nature of their chemical make-up or constitution. The distinction between thermoplastics and thermosets has become rather blurred with the development of new materials for more demanding environments than previously. They include high performance polymers which are more resistant to high temperatures, possess greater moduli or strengths, and can be combined with additives to enhance their intrinsic pr

Modeling irregular and complex forms
Computational technologies provide arguably the first real opportunity architectural design has had for a comprehensive description of built form. With the advent of affordable computer-aided design systems (including drafting, modeling, visualization and simulation tools), architects believe they can be in full control of geometric aspects and, through these, of a wide spectrum of other aspects that are implicit or explicit in the geometric representation. This belief is based primarily on the
