Dating Lava Flows on Mauna Loa Volcano, Hawaii
In this video segment adapted from NOVA, scientists search for carbonized remains of plants preserved in lava flows to find out how long it has taken rain forests on Hawaii to regenerate after a volcanic eruption.
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
Reusability of eLearning Objects in the context of Learning Grids
This paper examines the requirements of eLearning Object Metadata, in order to appropriately support pedagogic and economic goals as well as service oriented architectures like the Grid. The standard IEEE LOM is being tested against these requirements. In conclusion, it can be said that while current eLearning practices are well supported by the standard, the main insufficiencies concern a) the adequate description of ELOs that are services and not downloadable self-contained programs and b) th
Look and listen: Exploring the five senses
This group of shared reading lessons is based on the book "Look" by Jillian Cutting. They are designed to be used as a part of an integrated classroom unit on the five senses.
Determining the Sources of Delay in a Distributed Learning Environment
In the context of LeGE-WG we expect to see the Open Grid Services Architecture (OGSA) being used as a guiding framework for the future deployment of Distributed Learning Environment (DLEs). OGSA is totally service-oriented and it has been known for sometime that Quality of Service (QoS) is key to the success of DLEs. Delay in particular, as experienced by the end user, is one of the key QoS parameters for a DLE. This paper describes techniques for identifying sources of such delay, and a model f
Birds of a feather, an interdisciplinary unit: Language Arts wing
This lesson, which features Mark Twain's "Jim Baker's Blue-jay Yarn," is part of an interdisciplinary unit on birds that contains math/science and language arts components. In the language arts wing, students will explore dialects and personification through this very entertaining tall tale full of the antics of talking blue-jays.
Mars Dead or Alive: Mars Up Close
NASA scientist Steve Squyres narrates this visual tour from NOVA Online of the most revealing discoveries made by the Spirit and Opportunity rovers on Mars.
Lever an Obelisk
Investigate the mechanical advantage of the lever in this interactive activity from the NOVA Web site.
Discovery of Ideas and Ideas about Discovery : The influence of prior knowledge on scientific discov
Context of this research project. The empirical studies that were carried out for this thesis were performed in the context of the project 'Inductive Learning’,which was funded by the Dutch Organization for Scientific Research (NWO). The inductive learning project aimed at ‘clarifying the major constraints of inductive knowledge development’ (as stated in the research proposal). The constraints of inductive knowledge that were specifically studied in the project were prior knowledge, disc
An investigation of using the computer for reading and writing in the English classroom in secondary
This paper presents an investigation of using the computer in English teaching at the secondary school in the UK, particularly in respect of reading and writing skills. Many studies suggest that the computer brings significant possibilities for promoting the teaching of reading and writing in the English classroom. The computer can enhance the development of reading and writing. This study adopted interviews as research technique and some student teachers in a university and some English teacher
Interactive education: teaching and learning in the information age
This is a guest editorial to a special section of this journal which derives from the work of one of the ESRC Teaching and Learning Programme projects, InterActive Education: Teaching and Learning in the Information Age (http://www.interactiveeducation. ac.uk), whose overall aim is to investigate the ways in which new technologies can be used in educational settings to enhance learning. The project was predicated on two assumptions: first that teachers are central to learning in schools and that
How to Build A Road
Geology and weather introduced a variety of unexpected problems when construction crews were building the Alaska Highway. In this interactive activity from the American Experience Web site, see how Army engineers improvised solutions to blaze a trail through the wilderness.
How Should Our Gardens Grow?
In this lesson, students will learn about types of land use by humans and evaluate the ways land is used in their local community. They will also consider the environmental effects of the different types of land use. Students will assume the role of community planning engineers and will create a future plan for their community. (Note: Teachers will need to check out the following book from the local or school library: Durell, Ann, Craighead George, Jean, and Paterson, Katherine. The Big Book For
Development of Adaptive e-Learning System Based on Learning Objects
This paper discusses Adaptive Educational Hypermedia (AEH), which is at present a hot topic of research and an important aim for e-Learning systems. The presented approach is knowledgebased. The domain ontology and the learning objects play a central role as resources structuring the learning content and supporting flexible adaptive strategies for navigation through this content.
Tower O’ Power
In this activity, students learn about creating a design directly from a CAD (computer-aided design) program. They will design a tower in CAD and manufacture the parts with a laser cutter. A competition determines the tower design with the best strength:weight ratio. Students also investigate basic structural truss concepts and stress concentrations. Partnership with a local college or manufacturing center is necessary for the completion of this project.
Academic Use of Digital Resources: Disciplinary Differences and the Issue of Progression
This paper examines the use of digital resources by academics in UK Higher education. The explosive growth of the Internet and in particular the Web has led to a growth in speculation about networked and e-learning (Steeples and Jones 2003, Brown and Duguid 2000). Increasingly researchers have become aware of the ways the university resists such changes and provides a 'resourceful constraint' to the changes surrounding the introduction of networked learning (Brown and Duguid 2000, Cornford 2002)
Exploring the mathematics of motion through construction and collaboration.
In this paper we give a detailed account of the design principles and construction of activities designed for learning about the relationships between position, velocity and acceleration, and corresponding kinematics graphs. Our approach is model-based, that is, it focuses attention on the idea that students constructed their own models – in the form of programs – to formalise and thus extend their existing knowledge. In these activities, students controlled the movement of objects in a prog

Pea Soup Ponds
In this activity, students will learn how water can be polluted by algal blooms. They will grow algae with different concentrations of fertilizer or nutrients and analyze their results as environmental engineers working to protect a local water resource.
State of the art on Interaction and Collaboration Analysis
The document focuses on students-machine or students-students' interactions analysis that could support students & teachers, when students work in stand-alone mode or in collaborative technology based learning environments. The document concerns the State of the art on the interaction analysis dimensions and approaches that are already applied. The appropriateness of these approaches is related to the learning environments features, the user's profile, the learning activities, and the context of
