Lutilisation dun arbre des tâches pour concevoir et analyser des situations dapprentissage :
Afin de prendre en compte les difficultés que les élèves ont pour donner du sens aux activités expérimentales, ce qui leur fait perdre de vue lobjectif initial du T.P. et les connaissances visées, nous proposons de leur faire concevoir le protocole des expériences. À travers trois exemples de situations de T.P. mises au point et expérimentées dans des classes de Terminale S, nous montrons comment la structuration du protocole expérimental dans un arbre de tâche, permet d'analyser e
Autoregolazione dell'apprendimento e tecnologie didattiche
This paper introduces the concept of Self-Regulated Learning and analyses the possible support granted by Educational Technology for its practice and development.
It's About Interactive Learning
This paper draws on results of a research project InterActive Education: Teaching and Learning in the Information Age. The overall aim of the project is to examine the ways in which new technologies can be used in educational settings to enhance learning. To this end the project centres around the design and evaluation of teaching and learning initiatives for pupils from the age of eight to eighteen. Within this paper we report on our work with teachers and pupils, who have developed learning i
Changes in grouping practices over primary and secondary school
The research detailed in this paper provides a systematic description and analysis of classroomgrouping practices in primary and secondary schools in England. Practices are compared to main findings in developmental and educational literature with regard to effective contexts for learning and recent ideas about pedagogy. The research is based on an analysis of 4924 pupil groupings from672 Reception, Year 2 and Year 5 classes in 331 primary schools and 248 Year 7 and Year 10 classes in 47 seconda
Technical Paper 2 - The Effective Provision of Pre-School Education (EPPE) Project: Characteristics
In this paper the relationships between young children's entry assessments and various child (e.g. age, gender, ethnicity) and parent characteristics (e.g. educational and occupational background) are explored, to examine the extent to which variation between children in their cognitive and social-behavioural attainments can be accounted for by different factors. Marked differences between individual pre-school centres were identified in terms of the characteristics of children entering the EPPE
The RCBN Consultation Exercise: Stakeholder Report
One of the early objectives of the ESRC Teaching and Learning Research Programme (TLRP) Research Capacity Building Network has been to undertake an extensive consultation exercise in order to identify the priorities for research capacity-building and to generate a database of expertise from across the UK educational research community. This report provides an account of the first element of the consultation exercise, interviews with twenty-five key stakeholders each representing the major consti
This animation shows how to multiply matrices together. It shows that matrix multiplication is associative but not distributive.
Arithmetic in Java 1 (Storing numbers)
This is a simple learning object that illustrates how numbers are stored in the computer memory. It shows the effects of simple declaration and assignment statements. This object illustrates how memory is allocated and used to store numbers.
Adding and subtracting complex numbers
This animation shows how to add or subtract complex numbers, using a simple example
Manipulating Logs - Practice Test
A ten question test on manipulating logs (by addition, subtraction, multiplication, division
A number of examples of mathematical treatment of strong and weak monoprotic acids and bases, as well as buffers. The site presents a brief conceptual introduction to each case and then treats mathematically the steps to solve an example problem related to the concept.
Chemical Equilibria: The Law of Mass Action
Fundamental ideas and terminology of equilibria from a general chemistry perspective. A focus on closed systems, reversible chemical reactions, the law of mass action, Q and K. Also included are several multiple-choice questions that test the theories discussed. This site provides supplementary material that could be useful to beginning students in general and analytical chemistry.
A site with animation that provides a very brief introduction to the idea of separation of components in a mixture and a set of instructions for students for separating colored compounds by paper chromatography (on coffee filters). The appropriate audience would be students in a high-school or introductory, non major\'s college chemistry class.
Student Assessment of Learning Gains
This University of Wisconsin site is designed for instructors of all disciplines who would like feedback from their students about how the course elements are helping their students to learn. This page is a usable link for assessment, collaborative learning and technology in all college science courses by faculty or graduate students, although there is no particular focus on analytical science.
The History of Mass Spectrometry
This site provides a brief history of the development of mass spectrometry. The works of Thompson and Aston are presented along with a brief overview of the modern evolution of mass spectrometry. This site will be useful for beginning students interested in a historical overview of the field of mass spectrometry. This is an archived version of the site.
Introduction to Mass Spectrometry
This site contains an on-line text on mass spectrometry at the intermediate level. The text gives good general coverage of mass spectrometry instrumentation and applications in very readable format. It contains nice diagrams that provide a visualization of the ionization and mass selection processes. It also contains an overview of applications of mass spectrometry near the end that is different than most sites related to MS. It is especially appropriate for intermediate students.
Rheodyne - Application Support
Application notes, technical information, and on-line trouble-shooting guide pertinent for Rheodyne products (high-pressure valves).

L'image de l'Amérique au début de la colonisation : débat
Jean Paul Duviols tente de déterminer l'origine authentique du nom des trois caravelles de l'expédition vers le Nouveau Monde. Par la suite, ce sera sur la considération positive du rôle de Christophe Colomb parmi les conquistadors alors qu'en réalité c'est lui qui a initié ce profond mouvement de colonisation.
