Phi 1.618 ø PHI: The Golden Ratio or Golden Section (In Nature, Art, Science and Religion) The Golden Section is a unique Ratio (or relationship between parts) that seems to be preferred by Nature as the best geometry for growth, energy conservation, elegance and has some fundamental relationships to the platonic solids and the Mandelbrot set. It was formally discovered by the Greeks and incorporated into their art and architecture, but it has been shown to occur even in prehistoric art, possibly as a function of Man's natural affinity for it's beauty. The rectangle at left has a vertical edge length of 1 the horizontal or width of the rectangle is 1.618 If we make a line inside and form a square (far left) it creates another 'golden rectangle' (at right) this subdivision continues inward in a spiral fashion tracing the form of a perfect PHI spiral seen in galaxies, seashells .... Even your hand, arm, ear, teeth, etc are in PHI Proportions!
Apprendere con le tecnologie Metodologie per la didattica In questo spazio vengono raccolti gli articoli relativi alle varie metodologie didattiche utilizzate dai docenti. In particolare viene presentata la metodologia PBL – Project Based Learning. Comunicare con gli ipertesti Cosa è un ipertesto, come si usa ma soprattutto come si realizza: una guida per utilizzare con disinvoltura questa forma di collegamento fra informazioni poste in punti diversi di uno o più documenti e riuscire a sfruttarne a pieno tutte le potenzialità. Realizzare un sito Internet Questa lezione, utilizzata durante un corso di informatica spiega agli studenti come realizzare un Sito Web in modo gratuito e con semplici strumenti software. Esercitazioni in classe In questa sezione puoi trovare alcuni interessanti strumenti per realizzare esercitazioni, test, questionari e strumenti di valutazione per la tua classe.

Ressources pour tableau interactif Web 2.0 Tools for Math Educators By Laura Turner This is a continuing series on Web2.0 and other web-based tools for educators. This information is specific to math educators, but there is some crossover into science. Math educators will find a large number of useable interactive companion web sites for the teaching of math concepts and skills. 3Dvinci 3D design is a great motivational and instructional tool. Algebasics This site contains a variety of interactive Algebra help/ problems/activities Archimy This site has a service for drawing the graphs of all kinds of functions . Arcademic Skill Builder Our research-based and standards-aligned free educational math games and language arts games will engage, motivate, and help teach students. Calc3D This site has interactive Mathematical graph and charting software for geometry and statistics

Free Collaborative Writing Tool Mathway: Math Problem Solver Daniel Kopsas Daniel Kopsas (pronounced "Copsis") E-mail: kopsasd@otc.edu Office Phone: (417) 447 - 8263 Twitter: I teach mathematics at Ozarks Technical Community College in Springfield, Missouri. I was inspired by Maria Andersen from Muskegon Community College to create this site and continue to pursue the use of technology in the mathematics classroom. For each of the courses in the sidebar to the left, I have built or I am currently building math video libraries. These libraries are constantly evolving and are not by any means perfect or completely error-free. If you are an instructor who would like to use some of my tutorials, and not necessarily send your students to this page to dig, there might be a simple solution. The tools I used to create the videos are a Wacom Bamboo tablet ($70), a Logitech USB headset ($35), and two free software packages: Jarnal (the handwriting software) and Jing or SnagIt (the screen recording software). Feel free to link to my page.
Siti di aggiornamento How to Teach with Technology: Science and Math Students fire off ideas for using digital tools to teach scientific and mathematical concepts. Check out these tips from students and educators for high tech teaching: Science In former teacher T.J. Credit: Courtesy of DreamWorks SKG "The biggest thing needed for this project is an analysis of your resources," says Fletcher, who notes that in a project such as this, the teacher is not going to be the expert in all areas. "I let the students be the experts when it came to editing the videos," he adds. For inexpensive yet effective video cameras, he suggests trying Flip video cameras: "Their cost and durability make them an excellent choice for the classroom." Are You Game? Making video games will likely require some heavy lifting on the part of educators, but those interested in helping students create their own games can check out the World Wide Workshop Foundation, which, among other projects and resources, provides a program for teaching kids to design their own games.

The Metric System The Metric System By the eighteenth century, dozens of different units of measurement were commonly used throughout the world. Length, for example, could be measured in feet, inches, miles, spans, cubits, hands, furlongs, palms, rods, chains, leagues, and more. The lack of common standards led to a lot of confusion and significant inefficiencies in trade between countries. The simplicity of the metric system stems from the fact that there is only one unit of measurement (or base unit) for each type of quantity measured (length, mass, etc.). To simplify things, very large and very small objects are expressed as multiples of ten of the base unit. Table 1: Common metric prefixes. The subunits are used when measuring very large or very small things. The metric system is a called a decimal-based system because it is based on multiples of ten. Because the metric system is based on multiples of ten, converting within the system is simple. Scientific notation Key Conceptstoggle-menu
Tout comme le site Virtual manipulatives, celui-ci fournit des outils de mathématiques aux élèves de tous les cycles du primaire. L’enseignant peut faire appel à ces outils pour débuter une leçon en grand groupe. Il peut aussi l’utiliser pour modéliser l’utilisation de certains outils présents dans ce site. Ce site fournit des outils de mathématiques tels que le rapporteur d’angle, la règle, le compas, une minuterie, une balance, des dés, une table de multiplication, de division, d’addition et de soustraction, des tangrams, des roulettes pour travailler les probabilités, les blocs de base 10, etc. Une des limites de ce site est qu’il est en anglais. by amandinealexe Nov 12
