The historical development of the traditional U.S. high school biology–chemistry–physics sequence is detailed from the early 19th century to the present time. The recommendations of several important historical committees, especially the Committee of Ten, are described along with the sequencing practices adopted by the schools, to show how chemistry came to be the “Central Science”, that is the science taught in the middle of the high school sequence. It is shown that the present high school science sequence is more a product of historical accident than of educational design. The impact of this sequencing on high school chemistry enrollment is analyzed and discussed.
Supplement
Questions asked of all sub-committees, the 22 recommendations from the Physics, Chemistry, and Astronomy Conference, and the four programs suggested for high school by the full committee are available.
Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
Take JCE along on your outreach missions. Copies of the Journal, guest access to JCE Online, our publications catalog, and more are available for your participants.
