مستخلص: A sample of 211 inner-city fifth- and sixth-grade students participated in a study of the effects on achievement and independence of an individualized instructional program using multisensory, multimedia learning centers. Experimental and control groups differed in method of instruction but not in content covered. Results from pre- and post-course administrations of the California Achievement Tests indicated that the experimental group made significantly greater progress in reading, but not in arithmetic, than did the control group. It was also found that a greater number of experimental students than of control students displayed independence and self-direction. Differences in the experimental program's effectiveness with boys and girls, and with students of high and low ability, were also examined. (Author/AA)

مستخلص: The bimolecular electron transfer from primary aromatic amines to the parent radical cation of a nonpolar solvent results in the synchronous formation of an amine radical cation as well as an anilino radical. The interesting observation is that the yield of the anilino radical is not very significant. The upper limit for the direct formation of anilino radical is about 20%. This could be due to additional delocalization of electrons essentially reducing destabilization of the cation radical in their twisted form. The results were supported by pulse radiolysis reactions carried out in aqueous solution. Benzidine and o-tolidine reactions were carried out at pH 7 and 13 with various radicals, •OH, O•-, and •N3, to determine the yields of radical cations and anilino radicals. The molar absorptivity calculated in aqueous solution was used to determine the actual yield in nonpolar solvent after free electron transfer (FET). The above results were supported by quantum chemical calculations.
