The Educational screen (c1922-c1956])

42 The Educational Screen Group 'II taking the tests during the corresponding periods of the second day. As each boy took the seat assigned him, he was given eight 4x6 cards upon which had been written the numbers and titles of the slides for his group in the order in which they were to be shown. A preliminary study of the slides in the light of previous data would lead one to a prediction of unquestioned superiority for the colored slides. For, — All of the slides are copies of paintings. All save one, The Death of Abimelech, are rich in their portrayal of natural scenery. All portray people of other times, in costumes which were undoubtedly made of mani-colored materials. Only one. The Death of Abimelech, is rich in architectural detail.

The flags, scenery, and variety of costumes account, in part at least, for this superiority. The uncolored slide, The Death of Abimelech, achieves an almost equal superiority over its colored mate. This we may charge to the wealth of architectural detail if the findings of the previous studies referred to are reliable. A study of Table II is interesting in that it reveals that the four pictures, Washington at Fort Duquesne, Washington's Courtship, Washington Entering New York and The Peacemaker get the best results from either group no matter whether they are colored or uncolored.

Group II scored the highest total on all pictures, while in the present section of the experiment. Group I scores a superiority of .393 per pupil per slide. This may be interpreted as evidence that Group II had the best pictures in the first instance and Group I in the second, all other factors being equal. These slight superiorities in the reports of Group I are attributed by the writer to the fact that Group I had the most desirable picture for presentation in colors, Washington at Ft. Duquesne, with its out-door scenery, flags, decorations, and great variety of uniforms and costumes, and, also, the most desirable scene for uncolored slide presentation. The Death of Abimelech, with its fullness of architectural detail. Aside from these two scenes the differences are negligible. Of a total of 9117 statements for all slides, the colored slides achieved a majority of 51 statements. This means 6.37 per slide for each of the eight slides on the average, or an average superiority of .34, about one-third of a point per slide per pupil better than the uncolored slides. One-half of the pupils involved excelled with their four colored slides. Of the others, 68 excelled with their four uncolored slides and 8 did as well with uncolored as with colored slides.
