The stereoselective synthesis of an aryl vinyl bromide is accomplished in a rapid microscale reaction of "trans"-4-methoxycinnamic acid with N-bromosuccinimide in dichloromethane. The product is purified by dry column vacuum chromatography and its stereochemistry is determined by [superscript 1]H NMR. TLC, GC and GC-MSD can also be used. This…

This digest highlights the need for beginning environmental education based on life experiences during the very earliest years of life. The rationale for environmental education during the early childhood years is discussed, followed by guidelines for program development grounded on the belief that environmental education for the early years…

The independent variables considered were the concepts of ordered partitions and permutations, the level of consolidation or practice after discovery, and the teachers. Also considered were…

Reported are the suggestions indicated by research studies to seven questions concerning what is known about the teaching and learning of mathematics. (1) What factors influence the learner's achievement? Answer: Age, intelligence, and the amount of structuring present in the materials. (2) Are there guides for motivation? Answer: Games, concrete…

The examination by students of the associative property of a binary operation is used to illustrate how students can be involved in mathematical discovery. (MP)
