Structuring and merging Distributed Content
A flexible approach for structuring and merging distributed learning object is presented. At the basis of this approach there is a formal representation of a learning object, called attribute structure. Attribute structures are labeled directed graphs representing structured information on the learning objects. When two or more learning objects are merged, the corresponding attribute structures are unified, and the unified structure is attached to the resulting learning object.
The proving process within a dynamic geometry environment
Proof and proving have been objects of investigation from the point of view of mathematics and mathematics education for the past few years. Historical and epistemological studies show that proof is a crucial activity within mathematical practice. Didactical studies show that students encounter many difficulties when approaching proving in the classroom. Research at a cognitive level has developed frameworks interpreting students' difficulties. Studies concerned with the use of new technologies
Strong as the Weakest Link
To introduce the two types of stress that materials undergo compression and tension students examine compressive and tensile forces and learn about bridges and skyscrapers. They construct their own building structure using marshmallows and spaghetti to see which structure can hold the most weight. In an associated literacy activity, students explore the psychological concepts of stress and stress management, and complete a writing activity.
Just Passing Through (Lesson)
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 describes the function and components of the human nervous system. It helps students understand the purpose of our brain, spinal cord, nerves and the five senses. How the nervous system is affected during spaceflight is also discussed in this lesson.
A Robot in Kindergarten
These thought are the result of work in progress, started in 1999, within the scope of the Trás-os-Montes Digital/SCETAD, project (sub-project: ICEI – Computers in Early Childhood Education Contexts). The work took place in Portuguese kindergarten rooms, with children aged 3, 4, 5 and 6. The ICEI sub-project aims to promote the use of ICT in a playful but pedagogical way, be it free or directed. This use is intended to occur within the scope of activities developed for the micro-spaces of the

In this activity, students use wood, wax paper and oil to investigate the importance of lubrication between materials and to understand the concept of friction. Using wax paper and oil placed between pieces of wood, the function of lubricants between materials is illustrated. Students extend their understanding of friction to bones and joints in the skeletal system and become aware of what engineers can do to help reduce friction in the human body as well as in machines.
This laboratory activity gives an example of the creativity required when teaching non-native rock types. In order to study igneous and metamorphic rocks in central Florida (a huge area consisting solely of sedimentary rock), geology students examined building stones in downtown St. Petersburg. Each student picked a particular rock type used in a particular way (structure, decorative facade, etc.), performed geologic tests on it, read up on its properties, history, and uses, and prepared a paper
Alles Introductory Biology - Illustrated Lecture Presentations
These PDF files are Illustrated Lectures from his Earth history class (entitled introductory biology). The PDF files contain a lot of projection-ready graphics that may be useful in introductory Earth Science lectures. Lecture topics include the nature of science, cosmological evolution, biological evolution, life as a chemical function, The Hadean, Archean, Proterozoic, Paleozoic, Mesozoic and Cenozoic Eons, life and energy and biology and society.
A framework for processsolution analysis in collaborative learning environments
One of the most challenging aspects of computer-supported collaborative learning (CSCL) research is automation of collaboration and interaction analysis in order to understand and improve the learning processes. It is particularly necessary to look in more depth at the joint analysis of the collaborative process and its resulting product. In this article, we present a framework for comprehensive analysis in CSCL synchronous environments supporting a problem-solving approach to learning. This fra
Alternative Strategies to the Use of Vertebrates in Undergraduate Physiology Labs
There are many reasons to seek alternatives to the use of vertebrates, including cost and concerns with use of vertebrates in undergraduate laboratories. This major workshop explores examples of alternatives, including: a) an exploration of thermoregulation without using animals at all, b) an investigation of actomyosin function and membrane excitation using giant alga, and c) using insects to investigate taste receptors and digestion. This workshop explores the importance of providing good back

In this Design Challenge, families and friends work together to design the tallest structure that they can, using only the materials provided.
In this activity, students can select values for quadratic function coefficients, plot and explore multiple functions.
Decays Let Physicists Look Inside Particles
These pages invite students to test various particles for their decay products. Most particles studied by physicists are unstable; they decay. That is, given enough time by itself, one unstable particle will fly apart into two or more particles. By carefully observing and logically classifying these decays according to some well-understood laws of nature, particle physicists have been able to explain much about the fundamental structure of matter.
