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
The Chicken or the Egg: Agency and Autonomy in Informed Consent
One of the fastest growing global markets is pharmaceutical sales. With changing political landscapes and an increased awareness of new customers worldwide, sales have increased in Eastern Europe, Asia, and especially Latin America. As researches expand into countries with poor socio-economic and political infrastructures, guidelines such as the Helsinki Declaration, the Nuremburg Code, and the Belmot principles are being challenged. Regulatory and ethical guidelines have not
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.
A Closer Look at Oil and Energy Consumption
Students analyze international oil consumption and production data. They make several graphs to organize the data and draw conclusions about the overall use of oil in the world.
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.
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
Math Literature Connections: Patterns and Algebra
Ideas and activities that use Two of Everything, One Grain of Rice and the King's Chessboard to introduce students to function machines and input/output tables. Links to appropriate templates are also provided.

Gypsy Airs: Anna JiEun Lee
In this performance video segment from From the Top at Carnegie Hall, Anna JiEun Lee plays a virtuosic piece for violin by Pablo de Sarasate called Zigeunerweisen (Gypsy Airs), accompanied by pianist Christopher O'Riley. Listen for elements that are quick and dance-like, and others that are slow and mournful, as well as harmonies reminiscent of folk music. The music of the gypsies of Eastern Europe was the inspiration for the piece. (04:41)

In this Design Challenge activity students will explore how structure relates to function as they design devices to save Fido.
In this activity, students can select values for quadratic function coefficients, plot and explore multiple functions.
Oil and Sugar: Contemporary Art and Islamic Culture
The Institute for Contemporary Culture presented the third annual Eva Holtby Lecture on Contemporary Culture on November 20, 2008. Glenn Lowry introduces his lecture, Oil and Sugar: Contemporary Art and Islamic Culture, examining relevant and topical cultural issues of international scope.
Natural Inquirer Journals: Tropical
In the Tropical edition of the Natural Inquirer you will learn about different types of plants and animals. The tropics are the home of a variety of biomes, or regions with different kinds of vegetation and other life. Tropical biomes are largely defined by the amount of rainfall they get. In the tropics, you might find rain forests, dry forests, shrub lands, tropical plains called savannahs, and deserts. Scientists working in the International Institute of Tropical Forestry, or IITF, conducted
AlgTop13: More applications of winding numbers
We define the degree of a function from the circle to the circle, and use that to show that there is no retraction from the disk to the circle, the Brouwer fixed point theorem, and a Lemma of Borsuk. This is the 13th lecture of this beginner's course in Algebraic Topology, given by Assoc Prof N J Wildberger at UNSW.
The Law of the Internet
The Internet is at once a constructive and disruptive technology. As more and more of our lives move online, we are faced with opportunities to do new and amazing things. Concurrently, we encounter problems that no one anticipated as we collectively built the internet as we know it today. This seminar will consider some of the most intriguing of the issues to which the advent of the internet has given and continues to give rise. It will focus on a cluster of topics about which any computer user
