Trails of Digital and Non-Digital LOs
This document investigates scenarios where learners navigate (follow trails) through environments containing digital and non-digital learning objects, considers some user requirements of systems designed to support the use of trails and presents a possible classification of different types of trail to form an ontology of trails. Separate sections include investigations of trails in different pedagogical approaches, trails in mobile learning scenarios, trails in computer conferencing and the prov

Is support really necessary within educational games?
Games can be powerful learning devices because of their interactive and multimedia capabilities, and their abilities to keep students motivated, active, deeply immersed and engaged for sustained periods of time. Yet the extent to which this translates into more effective knowledge and skill acquisition is not clear from the research reported so far. Several researchers have stressed that support tools should be added to game environments to ensure that learning takes place. In this paper we will

Collaborative Ontological Engineering of Instructional Design Knowledge for an ITS Authoring Environ
Intelligence in an ITS authoring system could rely on content-based engineering of instructional design (ID) knowledge, i.e. based on principles such as conceptualization, standardization and theory -awareness. An ontology - based architecture with appropriate ontologies has been proposed for a theoryaware ITS authoring system. Ontological engineering (OE) as a collaborative process jointly conducted by an OE expert and an ID expert is presented as a step on a roadmap towards a theory-aware ITS

Mastering by the teacher of the instrumental genesis in CAS environments: necessity of instrumental
In this article, we study didactic phenomena identified in integration experiments within our classes, CAS(implemented in calculators). From this study, we show the interest of an instrumental approach to understand the influence of tools on the mathematical approach and on the building of students' knowledge: through a process - instrumental genesis - a calculator becomes a mathematical work tool; this process depends on the tool's constraints and potentialities, on students' knowledge, and on

Knowledge, the keystone of TEL design
This talk outlines the arguments supporting the claim that knowledge is the keystone of the design of Technology enhanced learning (TEL) environments. First, I consider the meaning we could attach to knowledge and knowing, and I introduce the notion of “conception”. Second, I explore how far the problématique of validation is central in our research. And to conclude, I introduce a characterisation of conceptions, which could help in addressing the problem of TEL design at a theoretical level.

An Introduction to the Simple Role of Numbers in Social Science Research
Social science is facing increasing demands for research involving 'quantitative' approaches. Among these are the need, expressed by policy-makers, for practical evidence about what works, and the demand, exemplified by the new ESRC guidelines for research training, that all researchers learn something about techniques of analysis involving numbers. At the same time, however, traditional 'quantitative' approaches are facing a major upheaval caused by growing criticism of null hypothesis signific

Using Pseudoscience as an Aid to Teaching General and Analytical Chemistry
This site developed by Michael Epstein, Margaret Bullard, Brad Buehler, and Robin Kloster, Department of Science, Mount Saint Mary\'s College contains case studies and experiments, used at this college in Maryland, that could be readily incorporated into an analytical chemistry course. Their inclusion of pseudoscientific topics include (a) lecture, discussion, and examinations; (b) demonstrations; (c) laboratory experiments; and (d) student attendance at a conference where controversial research

PBL Especially in the Context of Large Classes
This webpage from McMaster University in Canada describes one approach using small groups for using problem-based learning in teaching large classes. The focus of the authors is on teaching medical students but they also describe use of this approach in teaching civil engineering students, geography, etc. The approach described is likely to be of interest to analytical chemistry faculty teaching large classes of undergraduates as well.

Affinity Chromatography
This is an experiment showing the application of affinity chromatography to the separation of albumin from horse serum. A brief introduction of affinity chromatography and how it is being used in this specific experiment is given. This appears to be a good experiment to show the advantages of affinity chromatography in separating specific proteins from a complex matrix and would be useful in a biochemistry course or a course that is specifically looking at differing types of chromatography.

LSE Literary Weekend - How Would a Robot Read a Novel?
Don't judge a book by its cover? Don't be ridiculous. We constantly make judgements on books – from where it appears in a shop, its pretty cover, its heft or subject matter, the praise and criticism we hear about it. Reviewers are even more prejudiced. They know the author, or hate the publisher or, even worse, are a meticulous and lucid expert on the subject. All human readings are subjective. Is there another way? Would an objective reading - some preconceptionless robotic analysis, for inst

GlobalFIA
This site by GlobalFia provides a tutorial on the general aspects of flow injection analysis (FIA), sequential injection analysis (SIA) and the newly coined zone fluidics. Thus, it serves as an excellent resource for teaching flow methods to both undergraduates and graduate students, and as a refresher to practitioners. The tutorials are divided into 9 sections: introduction, fundamentals, dispersion, enrichment, chemistry, SIA, zone fluidics and bibliography. This modular approach makes inform

End Sequence Profiling Computational Lab - Oliver Hampton
Computational laboratory: Starting from a set of breast cancer BACs (bacterial artificial chromosomes) End Sequence Profiling (ESP) is performed. ESP analysis sequences the ends of insert DNA in order to characterize genomic rearrangements that may be involved in breast cancer progression. In this study, genomic rearrangements are characterized from 100 breast cancer BACs and 10,000 Fosmids (derived from a pool of the 100 originating BAC) using ESP.
