This paper examines technical writing at the high school level and suggests methods of teaching technical writing to students. Such topics are discussed as demonstration, mechanism description, causal analysis, detail, spatial order, and chronological order. It is argued that writing about objects can sharpen a writer's powers of observation and accuracy of expression. Two specific exercises are described: writing about razors and a modification of "Monopoly" to teach analysis of a total document for coherence. Technical writing in high school can also combat public doublespeak by making students more careful observers and wary consumers. (TS)
