Each ELF unit is available in three language versions (American Sign Language, Spoken English, and Manually Coded English).
You can view brief "snippets" of three units in the ELF Series, each unit showing a different language version by clicking on their links below. If you don't have the latest Flash Player, please download it to view the demonstrations.
The following demonstrations are videos of an actual child using the ELF Series. You will see the movement of the child's mouse on the screen as he interacts with the program. Do not use your mouse to click during the demonstration.
