Science in Focus: Shedding Light on Science: Workshop 7. Sun and Seasons
Light energy from the Sun is absorbed all over the Earth. In this workshop we will examine how the transformed energy heats the Earth unevenly, causing seasons.,The segment briefly describes past changes in the Earth's climate, possible reasons for these changes, and how the changes affected the Earth's inhabitats.

Scripting argumentative knowledge construction in computer-supported learning environments
Argumentative knowledge construction in computer-supported collaborative learning environments is often weak. This experimental study analyzes two collaboration scripts, which should facilitate argumentative knowledge construction. One script aims to support the construction of argumentation sequences and the other script aims to support the argument construction. These scripts should facilitate the argumentative knowledge construction on both the micro- and macrostructure of argumentation durin
Students will explore fractions, decimals, percents, and circle graphs with M&M's.
On the cognitive effects of learning computer programming
This paper critically examines current thinking about whether learning computer programming promotes the development of general higher mental functions. We show how the available evidence, and the underlying assumptions about the process of learning to program, fail to address this issue adequately. Our analysis is based on a developmental cognitive science perspective on learning program, incorporating developmental and cognitive science considerations of the mental activities involved in progr
A symbolic manipulator to introduce pupils to algebra theory
Within the theoretical framework of Vygotsky's theory, the paper presents a new algebra software. The main features of the software are described and their potentialities are discussed. According to the Vygotskian theory, expressions and commands may be thought as external signs of the Algebraic theory, and as such, they may become instruments of semiotic mediation: In other terms they can be used by the teacher, in the concrete realisation of classroom activity, according to the motive of intr
Studying Changes in Learning Environments BroughtAbout by ICT-Based Systems
Aim of our work is to briefly introduce the main aspects of a methodology for the analysis of individuals and environmental changes brought about by the introduction of Information and Communication Technologies (ICT) in learning environments. The theoretical framework underpinning our work is that of Activity Theory. More specifically, we draw on the Cole and Engeström modelling of the complex relationships between elements in an activity. We have worked out our contribution on the basis of th
Adding up using a calculator
This activity is designed to provide the student with the ability to key in prices in a calculator, add up a shopping list and work out how much change he should get. Suitable for students with Moderate Special Needs.
Virtual Reality for Learning: Sharing Experiences rather than Resources
Virtual Reality is becoming a major candidate for embodying immersive learning environments. Whereas in the two preceding decades learning has been conceptualized as situations where students are guided rather than elicited to undertake actions, it is now the right time to explore the other side or the continuum.

Architecture d’un environnement d’aide à l’apprentissage de la chirurgie orthopédique
Dans cet article, nous présentons le composant didactique et pédagogique d’un EIAH (Environnement Informatique pour l’Apprentissage Humain) pour la chirurgie orthopédique. Nous étudions l’architecture logicielle de ce composant, qui sera ajouté comme couche d’apprentissage sur un outil de simulation de planification d’une trajectoire de vis. Enrichir cet outil permettra à l’apprenant de l’utiliser pour acquérir l’expérience de la prise de décision chirurgicale pour la pl
Learning design based on graphical knowledge-modeling
This chapter states and explains that a Learning Design is the result of a knowledge engineering process where knowledge and competencies, learning design and delivery models are constructed in an integrated framework. We present a general graphic al language and a knowledge editor that has been adapted to support the construction of learning designs compliant with the IMS-LD specification. We situate LD within a taxonomy of knowledge models , namely the multi-actor collaborative system. We move
Évaluer l'utilisation d'hypermédias : intérêts et limites des variables de performance
Two main levels in describing hypermedia use can be distinguished. At a global level, the general purpose can be described in terms of learning or problem solving. At a more local level, specific goals can be described in terms of the learners' activity with the system, i.e. the visiting of one or more information nodes. In this paper, the influence of the nature of these local goals on performance variables such as recall, precision, and economy of hypermedia use are investigated. Specific char
Better By Design
The purpose of this activity is to use a scientific method to determine the effect of control surfaces on a paper glider. The students will construct a paper airplane/glider and test its performance to determine the base characteristics of the plane. They will then change one of the control surfaces and compare the results to their base glider in order to determine the cause and effect relationship of the control surfaces.
Just Passing Through
This lesson helps students explore the functions of the kidney and its place in the urinary system. Students learn how engineers design instruments to help people when kidneys are not functioning properly or when environmental conditions change, such as kidney function in space.
This lesson introduces students to the space environment. It covers the major differences between the environment on Earth and that of outer space and the engineering challenges that arise because of these discrepancies. In order to prepare students for the upcoming lessons on the human body, this lesson challenges them to think about how their bodies would change and adapt in the unique environment of space.

Distance Education Courses
ARCADE is a project aimed to develop an integrated software platform for authoring and delivery of Internet-based distance courses covering the university needs. Unified Modeling Language (UML) and Unified Software Development Process were applied as a basis for the project development. The Assessments and Assignments package provides computer supported instructional feedback (tests, projects, essays, problems). The IMS Question and Test Interoperability specification (QTI) defines the basic str
Kinetic and Potential Energy of Motion
In this lesson, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum, illustrating the concept of conservation of energy. Students calculate the potential energy of the pendulum and predict how fast it will travel knowing that the potential energy will convert into kinetic energy. They verify their predictions by measuring the speed of the pend
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
On-line Learning Networks: Frameworks and Scenarios
Progressively the idea of using the internet as a platform to mediate social interactions and learning at different levels has affirmed itself, and this has given rise to a huge number of spontaneous and planned collectives, which are often described as on-line learning networks. On-line learning networks create value from a combination of content and people knowledge. They can vary widely in the strength and permanence of their connections and resources necessary to maintain them. Aspects both
