Abstract
This paper aims to present the main objective and logic for new teaching contents in organic chemistry for high school chemistry education: “To distinguish between alkyl and functional groups in crude oil refining process based on hierarchy in nature.” The technical and historical analyses of crude oil refining were included in the contents, including the meaning of refining. The main objectives of crude oil refining are “establishing high quality by recognizing low quality,” and the meaning of refining is “making useful material from otherwise useless material.” The fundamental viewpoint of teaching contents is as follows: “An otherwise useless material becomes a useful material with inherent characteristics and not from any chemical change. In other words, an otherwise useless chemical substance may become useful by changing into another substance.” Based on the above considerations, the main objective and logic the teaching contents are presented.
