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.
Worksheet with keywords and a short form to fill out once a favorite film has been selected. Excellent for developing oral discussion skills in the area of cinema.
Derivation of Knowledge Structures for Distributed Learning Objects
Knowledge space theory (Doignon & Falmagne, 1985; Albert & Lukas, 1999; Doignon & Falmagne, 1999) offers a rigorous and efficient formal framework for the construction, validation, and application of e-assessment and e-learning adaptive systems. This theory is at the basis of some existing e-learning and e-assessment adaptive systems in the U.S. and in Europe. Such systems are based on a fixed and local domain of knowledge, where fixed means that the domain does not change in time and local ref
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
"A Most Awkward, Ridiculous Appearance": Benjamin Franklin Enters Philadelphia
When Boston native Benjamin Franklin entered Philadelphia in 1723, he had few coins in his pocket and scarce entrepreneurial skills. However, Franklin did have valuable training as a printer, and he came armed with some significant introductions to local printers. Printers and other craftsmen relied upon a network of masters, journeymen, and patrons to learn the craft and support themselves. Colonial printers needed expensive imported equipment, yet they had to make do with a limited market for
Puttin' It All Together
On the topic of energy related to motion, this summary lesson is intended to tie together the concepts introduced in the previous four lessons and show how the concepts are interconnected in everyday applications. A hands-on activity demonstrates this idea and reinforces students' math skills in calculating energy, momentum and frictional forces.
The Big Mo
Momentum is not only a physical principle; it is a psychological phenomenon. Students learn how the "Big Mo" of the bandwagon effect contributes to the development of fads and manias, and how modern technology and mass media accelerate and intensify the effect. Students develop media literacy and critical thinking skills to analyze trends and determine the extent to which their decisions may be influenced by those who manipulate a few opinion leaders. Note: The literacy activities for the Mechan
A Case of Innovation
A white paper is a focused analysis often used to describe how a technology solves a problem. In this literacy activity, students write a simplified version of a white paper on an alternative electrical power generation technology. In the process, they develop their critical thinking skills and become aware of the challenge and promise of technological innovation that engineers help to make possible. This activity is geared towards fifth grade and older students and computer capabilities are req
Build an Anemometer
Students create their own anemometers instruments for measuring wind speed. They see how an anemometer measures wind speed by taking measurements at various school locations. They also learn about different types of anemometers, real-world applications, and how wind speed information helps engineers decide where to place wind turbines.
Students follow weather forecasts to gauge their accuracy and produce a weather report for the class. They develop skills of observation, recording and reporting.
Bon Voyage to Bad Boating Habits
Students will learn about common boating-related threats to waterways. They will learn about the problems created in waterways by recreational boaters and discuss ways boaters can change their behaviors to reduce their impact on waterways. Students will also learn about the history of water pollution through a study of the Cuyahoga River. They will create a commercial to raise awareness about boating-related pollution. Exercises will also help students explore the reliability of information on t
Data Investigations: Codemaking and Codebreaking
There are resources for two activities 1. Cryptograms: These puzzles are familiar sayings that have been encrypted. Use letter frequencies, letter patterns and your best analytical skills to decode these familiar puzzles that can be found in many puzzle magazines or online. 2. Crypto-lists: These lists were designed to introduce students to code-breaking. Each list contains words that relate to the topic. Use letter frequency and your best analytical skills to decode these lists. Remember that e
Active Participation: Using Math Templates
Using math templates during instruction keeps each student actively involved and allows the teacher to informally assess each student's proficiency with the skills and concepts addressed in the day's lesson. Many teachers regularly use whiteboards to have students record answers, write terms, draw pictures, etc. The use of templates in sheet protectors extends this practice and eliminates the time spent drawing diagrams, etc., allowing students more time to demonstrate mathematical proficiency.
Jeopardy Games and Resources
Classroom Jeopardy Games are used by many teachers as review activities that challenge students to demonstrate proficiency in different areas of mathematics in order to win points for the team. Whether they are done in Power Point or on index cards, students are motivated to master the concepts and skills involved.
Math Activities for Fall (2006)
These activities were designed to introduce or reinforce important math concepts and skills using seasonal themes. The games capitalize on students' fascination with spiders at Halloween time.
Math Activities for Fall (2007)
These activities were designed to introduce or reinforce important math concepts and skills using seasonal themes. This is a natural fit for elementary classrooms where teachers and students celebrate the various holidays with literature and art projects. These activities allow teachers to also incorporate math activities that develop and support important mathematical concepts and skills.
Saint Gaudens' Memorial to Shaw and the Massachusetts 54th Regiment
This site focuses on the powerful memorial created to honor one of the first African-American units of the Civil War. Six sections of in-depth material explore the artist and his working methods, historical background on Shaw and the regiment, the memorial and its conservation, text from the exhibition, and teaching resources.
What is Matter?
Our understanding of atoms has been formed through decades of experimentation. In this activity, students learn about the historical developments of atomic theory while labeling the new discoveries.
Looking for a Top Quark Game
Graphing is an important tool used by scientists to interpret data. Students can practice their graphing skills while playing this game.
NASA CONNECT The Venus Transit
In NASA CONNECT Venus Transit, students will learn about the importance of using scale models to represent the size and distance of objects in the solar system and beyond. They will be introduced to the astronomical unit (AU), the baseline distance from the Earth to the Sun, which astronomers use to determine the relative distances from the Earth to other planets, stars, asteroids, and objects in space. They will also discover fascinating facts about the Venus Transit, a celestial and historical
