The Brain: Understanding Neurobiology Through the Study of Addiction
This site helps students discover the fundamentals of neurobiology and how drugs change the brain. Among the topics: functions of specific brain areas; anatomy of the neuron; neurotransmission; drug action on neurons; genetic, behavioral, and environmental influences on drug addiction; and addiction as a chronic disease.
Science and Technology of Mental Illness
This site provides six lessons that help students understand what mental illnesses are. PET images show changes in the brain and how treatment can change activity levels and restore functioning. Case studies and other activities explore differences among illnesses, risk factors, and treatment plan goals. Students develop a brochure to inform people about mental illness.
Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer is trying to find out if the student understands that even though you may mix two things together, the individual components still retain their properties.
Cofrin Arboretum Center for Biodiversity: Phenology
Gary Fewless, Herbarium Curator at the University of Wisconsin-Green Bay Cofrin Arboretum Center for Biodiversity, presents this online set of phenological data tables for the Great Lakes region. With records available for every month beginning February 2000, this Web site will ultimately provide "a long-term data base of regional phenology for scientists, educators, and nature lovers," with particular application to ecological and climate change research. Visitors are encouraged to submit their
Internet Scout Project
This website offers NASA's Earth Observatory newest feature -- an educational module about global warming. Beginning with a recap of the tremendous heat wave that struck Europe in the summer of 2003, the website proceeds with an educational discussion about the interaction between water vapor and other greenhouse gases and the atmosphere. Users can learn about climatic modeling and some assumptions that are incorporated into these models. Students can find out how NASA scientists utilize satelli
Looking At Learning ...Again, Part 2: Workshop 4. Conceptual Change
With Dr. Peter Hewson. In this workshop, we explore the role played by prior knowledge in the learning of new science ideas. Only when a new idea is understood, accepted, and found to be useful does it begin to be exchanged for a previously held scientific belief. The workshop examines how teachers ideas about teaching and learning may be altered as they engage students in strategies designed to promote conceptual change.,This interview discusses the conceptual change model, in particular that
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.
Peripheral Nerves from the course General Human Anatomy
General Human Anatomy - Fall 2006. The functional anatomy of the human body as revealed by gross and microscopic examination.
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.
Point/counterpoint commentary on the president's actions after the Brown ruling; from American Experience: "Eisenhower."
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.
