What is ENSIWEB?

ENSIWEB is a collection of classroom lessons to help high school biology teachers more effectively teach basic concepts in the areas of evolution and the nature of science. They were developed and tested during 10 years of summer institutes by biology teachers from across the nation (1989-1998).

The lessons were posted and refined with many supporting materials from 1997-2017 by Larry Flammer serving superlatively as webmaster for ENSIWEB. Larry Flammer died in 2017 (see https://ensiweb.bio.indiana.edu/faculty/index.html). Links to "webmaster" in the lessons and other materials in the resources throughout the ENSIWEB materials originally went to Flammer’s email account and are no longer operative.

How to find ENSIWEB resources

Although the ENSIWEB site is no longer actively updated, all the great resources for teachers and others are permanently archived and publicly accessible via the Internet Archive’s Wayback Machine.

Access ENSIWEB via the Wayback Machine

HOWEVER, some of the lesson links are "absolute" (contain the full URL), so they will try to take you to the lesson on the old site rather than to the archived lesson. If you have an old URL for the lesson you seek, you can still access it.

The URL for the ENSIWEB main page on the Wayback Machine site is https://web.archive.org/web/20180220170105/http://www.indiana.edu:80/~ensiweb/home.html. Replace “home.html” with the part of the old lesson URL that follows “~ensiweb/.” Because some of the links within the lessons are absolute links, they will also try to take you to the old site rather than to the next page within the archived site. You will need to use the same procedure above to find the linked page.
