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
This learning object covers how to determine the concentration of a substance in a mixture.
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. Links near the end of the document to pdf files contain u
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
Flow Injection Analysis
This website by Monash University provides a primer for those who are beginners as well as those who wish to have a refresher on the principles and illustrative applications of flow injection analysis (FIA). The left hand menu allows selection of topics: FIA, Princples, Dispersion Process, Modes of Applications, Recent Developments, Bibliography and People in FIA. Schematics and illustrative signal outputs are provided for each FIa method. The site is easy to browse with links to subtopics. Th
Liquid Chromatography Books
This site provides a list of books related to liquid chromatography and its applications. While not immediately pedagogically useful, it may be useful to those seeking texts about LC for their own research interests or to provide as references to students.
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
Integrated Spectral Database System for Organic Compounds
Searchable database of infrared, NMR, and mass spectra of organic compounds.
National Center for Case Study Teaching in Science
Compendium of web resources for faculty interested in incorporating problem-based learning and case studies in their courses. Case teaching notes, problem based learning. Article designed for faculty interested in incorportating case discussion in introductory and more advanced courses.
Exploring Amistad: Race and the Boundaries of Freedom in Antebellum Maritime America
Exploring Amistad examines the Amistad revolt, a shipboard uprising of slaves off the coast of Cuba. It uses timelines, a library of historical documents, a discovery section and bibliography to teach about this watershed historical event, which set off a legal, political, and popular debate over the slave trade, slavery, race, Africa, and ultimately America itself.
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. Analysis and comparison of both BAC and Fosmid
computer simulation of structural collapse
This is created by VFIFE (V-5, vector form intrinsic finite element) developed recently at National Central University, Taiwan. V-5 is capable of calculating position changes and body deformation simultaneously. It is based on the mechanics concept of Motion Analysis.
A National Study of Chronic Disease Prevalence and Access to Care in Uninsured U.S. Adults
Background: No recent national studies have assessed chronic illness prevalence or access to care among persons without insurance in the United States. Objective: To compare reports of chronic conditions and access to care among U.S. adults, by self-reported insurance status. Design: Population-based survey. Setting: National Health and Nutritional Examination Survey (1999–2004). Participants: 12 486 patients age 18 to 64 years. Measurements: Estimates of national rates of cardiovascular d
