Gooru is a new service (still carrying the Alpha label) that aims to provide teachers and students with an extensive collection of videos, interactive displays, documents, diagrams, and quizzes for learning about topics in math and science.
As a Gooru member you have access to hundreds of resources according to subject areas such as chemistry, biology, ecology, algebra, calculus, and more. Within each subject area you can look for resources according to media type such as video, interactive display, slides, text, and lesson plans. When you find resources that you want to use, drag them to the resources folder within your account. Gooru also offers you the option to add resources to your folders even if you did not find them within Gooru.
Screenbird is an online method of recording step-by-step tutorials and sharing them with colleagues, classmates, anyone. What I particularly like about it is there's no log-in required. Students can record their how-to, save it to a class wiki and create a collection of how-tos that everyone-even teachers-can use.
You can create a 30 minute video (Animoto's is 30 seconds)
Screenbird will host 150 minutes on their server, but you can create a lot more if you host it on your own wiki or YouTube.
You can capture the entire screen or just the part you want.
It's intuitive, allowing it to be more student-centered than other online tools.
There are great tutorials on the website. The class can watch the videos, test it out, and get help where needed.
