Bringing Together Chemistry Educators
The May 2014 issue of the Journal of Chemical Education is available online to subscribers.
The photochemical decomposition of aryldiazonium salts is the basis of the “diazo printing” technique (or “whiteprint”), used to reproduce technical drawings. In the article, Fear of the Dark: Diazo Printing by Photochemical Decomposition of Aryldiazonium Tetrafluoroborates, Fabio Parmeggiani describes a version of this technique that uses a recent, much less toxic synthetic method to create photosensitive paper that can be printed by exposure to UV light through a suitable template, and developed using ammonia. With the three couplers suggested in the article, it is possible to obtain prints in dark yellow, red, and purple, as shown on the cover.
Thomas C. Pentecost and Sherril Soman discuss the upcoming 23rd Biennial Conference on Chemical Education in Chemistry Education and Green Chemistry on the Third Coast .
Donald J. Wink provides clarity about the pedagogical and philosophical aspects of constructivism in Constructivist Frameworks in Chemistry Education and the Problem of the “Thumb in the Eye”.
