WHATEVER YOU TEACH, if you want to
BE THE MOST EFFECTIVE TEACHER YOU CAN BE,
you've GOT to add this widely acclaimed book to your toolkit:
Harry Wong's excellent book, filled with an abundance of practical, important, easy-to-find and use ideas for being the most effective teacher you can be. For practicality, this book may very well be the most important tool in your toolbox, the best well-spent money for your teacher education. Central is the critical importance of what you do the first day of school, and the few days which follow:

 AN ENSI-ORIENTED TEACHING SEQUENCE for BIOLOGY
An Overall Course Outline, Incorporating Evolution and the Nature of Science Thematically

 For a detailed article utilizing this approach,
with specific lessons choreographed into the curriculum,
see the "
The Evolution Solution" below

There are many ways to teach biology, many sequences which work. This suggested curriculum outline has worked very effectively. It is offered as a starting point to those looking for a curriculum revision which meets national and state frameworks and standards, and extensively incorporates important elements providing experience in the nature of science and evolution throughout, both fundamental to a deeper understanding of science in general, and biology in particular. Click here to see this list.

 The Evolution Solution:
Teaching Evolution Without Conflict

Observing life seems to contradict traditional ideas and raises tantalizing questions.
Show how evolution answers those questions and provides unity throughout your course.

Abstract: A strategy for teaching high school biology that opens with an intensive nature-of-science unit followed by question-raising topics, leading directly to evolution as a solution and a unifying theme. This special sequence - using specially designed student-centered lessons - is compelling and non-threatening for students.

Article by ENSI webmaster Larry Flammer in the March 2006 issue of the NABT Journal, new online version. Ideal for new teachers searching for an effective approach to teaching interactive biology with strong nature-of-science and evolution themes throughout. Classroom tested over many years. Direct links to many ENSI lessons and resources in context.

INTRODUCTORY UNITS for BIOLOGY
Detailed suggestions for effectively introducing the nature of science and evolution
early in your biology course, suggesting sequence and content derived largely from
the ENSI lessons, and reflecting the ENSI philosophy.
Offered by ENSI teacher and webmaster, Larry Flammer, ENSI 1992

 

 NATURE OF SCIENCE...
........pre-test, what science IS, is NOT, and its limits...correcting the misconceptions. Includes a look at Illusions, both natural and intentional, and how these can be used to teach the nature of science.

CLASSIFICATION: Survey of life; terminology and concepts, and some problems
.........Using furniture, hardware, etc. as example of arbitrariness in biological classification sends WRONG message about the nested hierarchy of RELATED groups. See lesson for a far more valid introduction to classification: Classification: Arbitrary or Not?.
.........Problems in classification are many. Most relevant here are those forms which do not fit neatly into the classification categories we've recognized. Examples: archaeopteryx, platypus, peripatus, lungfish. Each seems to fit equally into two major groups. Leads naturally into topic of evolution, which provides most reasonable resolution to this problem.

HUMAN EVOLUTION:
Comparative anatomy....skulls.....of hominoids (apes and hominins)
Chronology of hominin fossils...and gradual changes....
Comparison of hominoid chromosomes
Molecular Sequences & Primate Evolution (amino acid sequences)
Classification lesson (Multiple Lines of Evidence, pointing to...human evolution)

INTRO TO EVOLUTION...
........pre-test, what it IS, and is NOT....correcting the misconceptions

 A FULL YEAR CURRICULUM FOR 7th GRADE LIFE SCIENCE
by Nate Fairchild
A suggested course sequence that works well,
(especially with students who oppose evolution),
along with a
detailed outline of his introduction to evolution

Nate Fairchild, is a dynamic middle school science teacher in Redding CA. He has a website on which he details his approach to teaching a very effective and comprehensive introductory unit on evolution (as well as incorporating the concept throughout his course) in a community with many anti-evolution families. He sent me this comment recently:
"Ultimately, it's all about learning and replacing dogma with logical thought. I have been very happy with this approach, and since it approaches the kids from left field, I do not get any (ANY!) complaints from parents, though I am sure one day I will. I feel very strongly that in a community like mine I might as well not teach evolution if I stood up and said, "OK, this is a unit on evolution and you can believe what you want." Ugh." I would add that we have an obligation as life science teachers to help students recognize inaccurate claims and concepts about science and scientific topics, and to do all we can to replace them with the most accurate and current scientific information, while making it clear why science cannot use supernatural explanations. We can do this without compromising basic religious beliefs, and certainly with respect and sensitivity for students with those beliefs. We must be as effective in this as we can.

STRATEGIES FOR TEACHING EVOLUTION
by Craig E. Nelson

 

ENSI Co-Director, Craig Nelson, has compiled a collection of about a dozen
"Effective Strategies for Teaching Evolution and Other Controversial Topics".
The Published Version is available from NSTA in the booklet titled: The Creation Controversy and the Science Classroom. (2000). Click on the title to order from NSTA Book Store. It is 32 pages long (pages 19-47), and is well-worth purchasing from NSTA for about $15 (same web page).

Craig's comments:
"In this I propose about a dozen specific strategies. Some of them suggest teaching young-earth and progressive and gradual creation as well as non-thesistic evolution in science classes IF AND ONLY IF they are taught in a framework that commpares their scientific strength and asks what views on non-scientific consequences might lead one to adopt each of them. This seems to me to fit with the view from physics that the only way to deal with alternative conceptions in science is to put them on the table, ask how they match the evidence and also ask why many people prefer them."

"I realise that some of the strategies I have used and present may not be prudent in some local political situations (though we have found that many high school teachers do find them useful even in quite conservative communities)."

An example of one spin-off from this rich reservoir of teaching ideas is a one-page summary and example for teaching the criteria for critical thinking and how we can use the Fair Test to get the best explanation. Take a look at this: "Fair Tests: A Basic Model for Critical Thinking in Science". If you use this in your classes, be sure to let us know how it went, and what additonal ideas you may have used to improve its effectiveness.

Another spin-off from Craig's rich reservoir of teaching ideas is an activity which has students comparing the strengths of different scientific ideas in "Is Evolution Weak Science, Good Science, or Great Science?" Take a look at it, and TRY it!

In addition, please let us know about ANY of your efforts to implement ANY of the suggestions presented by Craig. We are anxious to share these ideas with other teachers.

Reviw and Links by Larry Flammer

How would you like to see your students increase their accurate explanations of evolution from 6% before the unit, to 92% afterwards? Likewise, wouldn't it feel good if the number of your students accepting evolution as a viable explanation of diversity went from 59% before your course to 92% afterwards? These are the kinds of results obtained from a closely monitored approach to teaching evolution. The students were 141 college non-majors in a course that devoted about 7.3 hours (4 weekly 110-minute labs) to the assessment and teaching of evolution.
