Essential Science for Teachers: Life Science: Session 4. Plant Life Cycles
What is a plant? One distinguishing feature of members of the Plant Kingdom is their life cycle. In this session, flowering plants serve as examples for studying the plant life cycle by considering the roles of seeds, flowers, and fruits. A comparison to animal life cycles reveals some surprising similarities and intriguing differences.,Children's ideas about seed are discussed, with references to BSCS TRACKS. Children are about 7/8 years old. They soak lima beans and see the plant embryos. A
Essential Science for Teachers: Life Science: Session 2. Classifying Living Things
How can we make sense of the living world? During this session, a systematic approach to biological classification is introduced as a starting point for understanding the nature of the remarkable diversity of life on Earth.,This segment deals with the "other" organisms that do not easily fall into the plant or animal category. 7 year olds talk about a third ring to the Venn diagram and that bacteria would be an "other".

Its website, in addition to providing information about the organization and the benefits of membership, including the association's annual symposium scheduled September 9-12, 2005, in Vancouver, also includes several features that will be of interest to the broader community of gardeners. Visitors may peruse an extensive listing of books aut
Microscope Imaging Station
This site shows what blood is, what happens when the immune system goes awry, what are stem cells are, and more. See videos exploring cell structure and function, cell development and motility, plankton, plants, and protozoa. Learn how the sea urchin helps us understand genes, reproduction, and cancer.
Essential Science for Teachers: Life Science: Session 3. Animal Life Cycles
One characteristic of all life forms is a life cycle—from reproduction in one generation to reproduction in the next. This session introduces life cycles by focusing on continuity of life in the Animal Kingdom. In addition to considering what aspects of life cycles can be observed directly, the underlying role of DNA as the hereditary material is explored.,Students are asked what existed before a bird becomes a bird? Students explain their ideas about eggs and birds. They present interesting a
Détermination automatique des théorèmes-en-acte des élèves en algèbre. Le cas des équations e
Dans cet article, nous sommes intéressés à la détermination automatique de théorèmes-en-acte en algèbre. Ces théorèmes-en-acte ont été construits de façon abstraite, puis nous avons cherché à automatiser le mécanisme de leur diagnostic. Pour cela, nous avons utilisé le logiciel Aplusix comme support des productions des élèves qui permet d'enregistrer toutes les actions des élèves. Une base de règles correctes et erronées a été mise en place et un interpréteur de règles
Book Writing and Wall Writing from the course History of Information
This course explores the history of information and associated technologies, uncovering why we think of ours as 'the information age.' We will select moments in the evolution of production, recording, and storage from the earliest writing systems to the world of Short Message Service (SMS) and blogs. In every instance, we'll be concerned with both what and when and how and why, and we will keep returning to the question of technological determinism: how do technological developments affect socie
Passive Building Design - student example 3 (Laura Graham) An interactive website showcasing passive design methodology, completed as part of third year coursework for a Bachelor of Using the World Wide Web to Build Learning Communities in K- 12 Manned Mission to Mars Dating Lava Flows on Mauna Loa Volcano, Hawaii Thanksgiving story, "Stone Soup" Multimedia and the learner's experience of narrative Learning with Digital Technologies in Museums, Science Centres and Galleries Competence-based Knowledge Structures for Personalised Learning Towards Collaborative Learning via Shared Artefacts over the Grid Informations- og kommunikationsteknologi i gymnasiet - i et læringsperspektiv.
Social accounts of learning and human knowledge have led to attempts to reorganize schools as learning communities. This paper examines the utility of World Wide Web (WWW) for aiding in the construction of school-based and work-based learning communities An ordered list of interactions is provided to characterize the depth of students entry into new learning communities. Current offerings on the WWW are then surveyed in terms of these categories. Finally, proposals are advanced for enhancing the
This lesson will discuss the details for a possible future manned mission to Mars. The human risks are discussed and evaluated to minimize danger to astronauts. A specialized launch schedule is provided and the different professions of the crew are discussed. Once on the surface, the crew’s activities and living area will be covered, as well as how they will make enough fuel to make it off the Red Planet and return home.
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.
This lesson is for K-5 Exceptional Children who are mild to moderately disabled. This lesson will incorporate listening, daily living, fine motor, and augmentative communication skills.
This paper reports on research findings which show that the narrative structure of multimedia programs, or sometimes the lack of it, affects learners' comprehension, often adversely [1,2].
It also reports on initial findings from our current research which aims to develop a theoretical understanding of the forms and functions of narrative in interactive media, based on empirical
research, and capable of informing instructional design.
As early as 2002 the number of virtual visitors to many museums' websites had already overtaken the number of physical visitors on-site. These developments, both within the walls of the institution and outside them, provide a number of challenges for educators and curators, at the heart of which lie the questions - what is distinctive about learning in museums, science centres and galleries, and how might this change or evolve through the increasing use of digital technologies?,A NESTA Futurelab
The ELeGI project focuses on integrating technology-enhanced learning methodologies into a pedagogy-driven and service-oriented architecture based on Grid technology. It aims at a system that is capable of realising personalised, adaptive, and experiential learning.
This requires to have available a framework that, on the one hand, allows for representing existing domain knowledge, and, on the other hand, provides a representation of the learner's current state of knowledge. It is shown that a
The Web is the most pervasive collaborative technology in widespread use today; and its use to support eLearning has been highly successful.
There are many web-based Virtual Learning Environments such as WebCT, FirstClass, and BlackBoard as well as associated web-based Managed Learning Environments.
In the future, the Grid promises to provide an extremely powerful infrastructure allowing both learners and teachers to collaborate in various learning contexts and to share learning materials, lea
This thesis deals with the integration of Information Technology (IT) in the upper secondary school, seen in a learning perspective. The object of the thesis is to understand the developmental dynamics of IT, peda-gogy and learning, and how IT can facilitate qualitative changes in the upper secondary school. This is examined through the construction of a theoretical outlook, and through analysis of an empirical investigation.,Master thesis also published online in the online Journal Impact
