Techniques in Organic Chemistry is a compilation of short video segments designed to teach the basic techniques (1, 2) of organic chemistry to undergraduate university or college students. Produced by Lois M. Browne and several teaching assistants in chemistry at the University of Alberta, Techniques in Organic Chemistry uses a unique style to demonstrate different practical lab skills. The set is designed to help students envision the procedural steps of basic techniques of organic chemistry in a concise, visually interesting, engaging, and unequivocal way. Procedures are performed by "stage hands"--only the demonstrators hands and the equipment used are visible. Part 1 of Techniques in Organic Chemistry is a VHS videotape that contains approximately 60 minutes of video segments describing the following techniques: the proper manipulative methods for handling chemicals safely; three types of filtration and when to use each; recrystallization of a solid using a single solvent; recrystallization of a solid using two solvents; product analysis by thin layer chromatography. Part 2, with five additional segments, is scheduled for publication later this year. In Techniques in Organic Chemistry the emphasis is on the basic manipulative skills of the procedure. Each video segment is presented in a similar format. First, teaching assistants introduce the technical method and explain the underlying fundamental purpose. Next, the step-by-step procedure is detailed by "stage hands" as voice-over narration explains what is happening. In this section, only the equipment and the demonstrator's hands are visible to stress the proper technique and setup of apparatus. Common technical errors are addressed. Throughout the video, colorful graphic illustrations reinforce the step-by-step procedure and provide the final review of the technical method. Colorful graphics reinforce the techniques demonstrated and correct common technical errors.

Alternate ways to perform these procedures exist and may be preferred at your institution. Students should be aware of options and should follow local preferences, understanding that there are fundamental steps associated the proper handling of organic chemicals. Each technique is introduced by a teaching assistant. Above, Craig and Phil introduce a technique in English. Below, Karine and Shirley provide the introduction in the French version. A French version, Techniques de Chimie Organique (approximately 60 minutes), is included. Techniques de Chimie Organique is translated, narrated, and coproduced by Karine Auclair. Hardware and Software Requirements This videotape requires an NTSC VHS videocassette player and a color video monitor such as a television set. A large screen monitor or a video projection device may be desirable. Acknowledgement Stage Hands: Minh N. Vo, Sandra L. Kenefick, Neal N. Fong Graphic Illustrations: Marcia Anstee, Minh N.
