Exploriments is a site that has interactive simulations that help students learn and understand math and science. Students are active and engaged, rather than passive. They get to explore different topics and ask, and answer, questions like "what-if" and find the cause and effect of things. There are learning objectives for each Exploriment and everything works together and builds on previous knowledge.
The Exploriments are organized by Physics, Chemistry and Math and then further organized by topic. The physics ones are well done and I've used a few with my students already.
The free access does not give you full access or function, but there are some great things to use. You can upgrade to the premium access if you want to.

Computers and tablets are only assistants and a good teacher’s will always be needed.
ReplyDeleteHowever social networks such as facebook and YouTube as well as great resources including Wikipedia and Wolfram-Alpha are here to stay so that educators must use them in the teaching process.
Some time ago YouTube moved a lot of their educational content to a separate domain giving people access a broad set of educational videos.
However, some complaints include the variety of the content found there as well as the need for schools to register on YouTube under the academic section in order to show their videos, leaving out many academics, professionals and students not formally associated with mainstream schools which contribute with great videos.
Many academics are posting great educational videos and materials online. The only problem is to sort the good ones from the rest and present them in an organized manner.
This effort is being done by: http://utubersity.com which presents the best educational videos available on YouTube in an organized, easy to find way to watch and learn. It also links the videos to related content in Wikipedia or associated websites.
They are classified and tagged in a way that enables people to find these materials more easily and efficiently and not waste time browsing through pages of irrelevant search results.
The website also enhances the experience using other means such as recommending related videos, Wikipedia content and so on. There's also a Spanish version called http://utubersidad.com
