Etude de connaissances d'élèves de seconde sur les mutations génétiques.
L'ADN est une notion qui pose problème aux élèves de lycée aussi nous nous proposons d'identifier et de classer les conceptions des élèves sur ce sujet.
Pour cette analyse, nous avons utilisé la notion de mutation, qui permet d'étudier à la
fois, comme nous le souhaitions, la structure et la fonction de l'ADN. Après avoir effectué une étude bibliographique et une analyse du savoir, nous avons cherché à vérifier l'existence de six niveaux biologiques dans les productions des élèv
Un extracteur de fumée (video)
Pour dégager une bouteille pleine de fumée, on y produit un fort dégagement de chaleur et les gaz qui s’échappent entraînent les particules de fumée.
Integration of adaptive learning processes with IMS Learning Design considering corporate requiremen
D1.11 deals with standards and integration, especially with four topics: IMS Learning Design, Adaptation, Integration and Corporate Requirements. It attempts to emphasize the needed relationship among them in order to improve the personalized learning. Based on academic research, our findings take also into account the specific features of corporations. D1.11 is closely related to D1.10, where several taxonomies of learning processes and learning categories are presented, which are used in D1.11
Moursund Mathematics Lecture Series. Dr. Jacob Lurie, Lecture 2: “Ambidexterity”
In classical algebraic geometry, there is often a stark difference between the behavior offields of characteristic zero (such as the complex numbers) and fields of characteristic p (such as finite fields). For example, the equation x^p = 1 has p distinct solutions over the field of complex numbers, but only one solution over any field [...]
Making & Breaking: The Rock Cycle
Students learn the components of the rock cycle and how rocks can change over time under the influence of weathering, erosion, pressure and heat. They learn about geotechnical engineering and the role these engineers play in the development of an area of land, the design and placement of new structures, and detection of natural disasters.
Rock Jeopardy!
Students reinforce their understanding of rocks, the rock cycle, and geotechnical engineering by playing a trivia game. They work in groups to prepare Jeopardy-type trivia questions (answers) and compete against each other to demonstrate their knowledge of rocks and engineering.
The LEAP Authoring Tool: Supporting complex courseware authoring through reuse, rapid prototyping, a
An important goal of current work in computer-based learning environments is to develop systems that combine the richness and effectiveness of an individually crafted intelligent tutoring system (ITS) with the generality and flexibility of a computer-assisted instruction (CAI) authoring tool. Our effort to achieve this goal is demonstrated in the Learn, Explore and Practice (LEAPsm) ITS shell and its courseware development component, The LEAP Authoring Tool (LAT). The LAT was developed for use b
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer probes to find out the student's ideas about the process of how rock was broken down to form sand. The student indicates tides as the factor. The interviewer probes further to ask the student about waves and the student tries to connect the waves to his idea about tides. The interviewer also uses familiar phenomena such as what happens to you when a wave hits you as well as providing water for a s
Cell Biology Improvement Drive
Wikiversity participants with an interest in Cell biology can participate in the "Cell biology improvement drive". This Learning Project is a service-oriented Wikiversity project devoted to improvement of Cell biology articles at Wikipedia and development of the Wikibooks textbook about Cell biology. Participants in the project can become involved in the construction of new Wikiversity pages that are concerned with Cell biology. This "Cell biology improvement drive" also includes improvement of
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer builds on the student's prior knowledge about sand coming from rock by probing further to find out her ideas about how the sand ends up on a beach. He probes beneath her responses by trying to uncover why she thinks the sand comes from the ocean and why she thinks waves make sand out of rock. He challenges several ideas by asking her for an explanation and presenting other phenomena such as what
How to Make a Candy Cane Vase
This short video teaches how to create a beautiful candy cane vase using peppermint sticks, old jars, flowers, rubber bands, etc. This is a great resource for a last minute entertaining idea or gift. (2:39)
An Advisory QoS Service for GRID Based Learning Environments
This paper argues that the assumption of end-to-end QoS provision for use in Grid based applications is unsafe. We present an architecture which provides an adaptive QoS service for GRID applications which are prepared to adapt rather than assume the best and then suffer the worst.
This is particularly relevant to Internet based GRIDs. An example application from the field of collaborative learning environments is given, featuring adaptive QoS for Real Time Protocol (RTP) based audio and visual
Soapy Stress
To experience the three types of material stress related to rocks — tensional, compressional and shear — students break bars of soap using only their hands. They apply force created by the muscles in their own hands to put pressure on the soap, a model for the larger scale, real-world phenomena that forms, shapes and moves the rocks of our planet. They also learn the real-life implications of understanding stress in rocks, both for predicting natural hazards and building safe structures.
Group Reflection Tools for Virtual Expert Community - REFLEX Project
The aim of this project is to improve work quality, creativity and performance in various professional communities of knowledge-intensive companies by integrating teamwork and learning in collectively designed information spaces. This project will provide a pedagogical model for building and sharing expert knowledge within physically distributed teams that have a need to collaborate and co-ordinate information. The project will utilize latest information and communication technologies in develop
Conclusion This free course provided an introduction to studying education, childhood & youth qualifications. It took you through a series of exercises designed to develop your approach to study and learning at a distance and helped to improve your confidence as an independent learner.
What have the Romans ever done for us? - Global Europe from a Dutch perspective
Frans Timmermans will address issues of the changing political economy and the role the European Union can play in facing the challenges of today. The soft power of the EU is no longer limited to stabilisation and transformation of societies alone. Europe sets the standard in many fields. Yet, as Frans Timmermans will argue, pursuing the vision of Europe as a model power imposes a growing need for the Union's member states to start thinking and behaving in political terms. Less as a collection o
Human Rights in United Nations Action: Norms, Institutions and Leadership
Navanethem Pillay is UN High Commissioner for Human Rights, she took up office on 1 September 2008. Ms. Pillay, a South African national, was the first woman to start a law practice in her home province of Natal in 1967. Over the next few years, she acted as a defense attorney for anti-apartheid activists, exposing torture, and helping establish key rights for prisoners on Robben Island.
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer is trying to find out if the student can explain how the sand got onto a beach. It shows how a representation (the map of Cape Cod) and familiar experience (going to the beach at Cape Cod) are used to try to guide the student in sharing her reasoning about where the sand came from.The segment does not address the part of the benchmark about seasonal layers.
Stratigraphic Framework of Lower and Upper Cretaceous Rocks in Central and Eastern Montana
This USGS report focuses on Cretaceous rocks in Montana with respect to natural gas and coalbed methane. The study includes the stratigraphy from the top of the Mowry Shale to the base of the Judith River Formation. The project integrates geologic, structural, hydrologic and engineering studies with known and new geochemical data on the gas and co-produced water. The report also facilitates an understanding of the controls on the spatial distribution of potential gas accumulations. Figures, tabl
