A device for training people to improve reading skills, comprising:
- means for isolating a single line of reading material to be read from a page containing a plurality of lines of readable material including a frame having an open left end, and open right end and having at least one elongated member defining a trough between said open ends, one of said members having an edge underlying said single line of reading material, and said frame including a first stop pin mounted on the left end of the frame and a second stop pin mounted on the right end of the frame;
- and
- shutter means slidingly mounted in the trough of said isolating means for sequentially uncovering portions of said single line of reading material, whereby a reader may attack selected portions of said single line of material as said shutter means is moved from left to right on said isolation means, said shutter having a left edge and a right edge, each of said edges being capable of movement out of said open ends so that the opposite edge is positioned near the edge of the printed margin of the page, said left edge of said shutter being adapted to uncover portions of said line sequentially as said shutter is slid laterally along in said trough, said shutter being provided with an upper dead end groove and a lower dead end groove, said upper dead end groove being open adjacent one ege of the shutter in alignment with one of said pins and being closed between said edges in a location permitting movement of the opposite edge of the shutter past one margin of the page, said lower dead end groove being open adjacent the other edge of the shutter in aligment with the other pin and being closed between said edges in a location permitting movement of the opposite edge of the shutter past the other margin of the page.
