Slideshows  Secondary
These slideshows help teachers discuss key elements of the "Electronic Textbooks."  They are created  to be used with projection computers or big screen television with computer hook ups.  Students can review materials at home, so they better understand the lectures. We are developing these with grants and memberships, so please be patient. (Additional slideshows)
