Abstract: Several pictures portraying varied mixed racial groups of children in either a middle-class suburban setting or a lower-class intercity setting were used as part of a 1-mo. long curriculum unit. Wh...

Relative energetics of modes for phosphorane formation and decomposition in nucleophilic displacement reactions at acyclic phosphorus. Alkaline hydrolysis of alkoxy(alkylthio)phosphonium salts

Abstract: Der Verlauf und die Stereochemie der Hydrolyse der Salze (I) (dargestellt durch O-Alkylierung der entsprechenden Phosphinothiolate bzw. durch S-Alkylierung der entsprechenden Phosphinothionate mit den betreffenden Trialkyloxonium-hexafluoroantimonaten) werden untersucht.

The Affective Side of the Schooling Experience.

Abstract: The affective reactions that pupils have to their schooling experience may be the most important aspect of school. Unpleasant school experiences seldom attract pupils. When the beauty and the importance as well as the substance of a subject are taught, when pupils appreciate the importance and the usefulness of what they are learning, education is an exciting, growth-producing experience. Sometimes pupils learn to dislike, and then to avoid, the subject they are studying. Perhaps the basic objective is to send pupils away from in-
