Learning Exercise


Material: The Biology Project: Mendelian Genetics
Submitted by: Kara Carmody on Dec 16, 2002
Date Last Modified: Dec 16, 2002
Title: Web-Based Mendelian Genetics Problem Sets
Description: Students will individually complete the online problem sets at the following website. The problem sets available are Monohybrid Crosses and Dihybrid Crosses. Students will then create two appropriate crosses for the problem sets.
Type of Task: Individual, Student-centered
Time Required 1 hour
Topics: Mendelian Genetics: Monohybrid Crosses & Dihybrid Crosses
Course: Advanced Biology/ Genetics Unit
Audience: High School
Categories:
Prerequisites Skills: Students will have had practice with both monohybrid and dihybrid cross problems. This assignment will be used near the middle of the unit. It will serve as a review for the monohybrid problems and practice on the newly introduced dihybrid prolems.
Learning Objectives: Students will develop problem solving skills for both monohybrid and dihybrid cross problems.
Students will construct multiple choice monohybrid cross and dihybrid cross problems that demonstrate their conceptual understanding of the material.
Students will become familiar with answering online problem sets, as well as traditional means through problem composition.
Text of Learning Exercise: Web-Based Mendelian Genetics Problem Sets

Topic: Mendelian Genetics: Monohybrid Crosses & Dihybrid Crosses

Objectives: Students will develop problem solving skills for both monohybrid and
dihybrid cross problems.
Students will construct multiple choice monohybrid cross and dihybrid cross
problems that demonstrate their conceptual understanding of the material.
Students will become familiar with answering online problem sets, as well as
traditional means through problem composition.

Introduction:
Students will have had practice with both monohybrid and dihybrid cross
problems. This assignment will be used near the middle of the unit. It will
serve as a review for the monohybrid problems and practice on the newly
introduced dihybrid prolems.

Task:
Students will individually complete the online problem sets at the following
website. The problem sets available are Monohybrid Crosses and Dihybrid
Crosses. You are expected to work out the problems (create Punnett Squares,
etc.) as you go through the set. You will be required to turn in your work for
both problem sets. If you answer a question incorrectly, utilize the tutorial
to help you understand the correct answer as well as to amend your answer on
your paper. Your grade is not dependent upon the number of questions you
answered correctly the first time, but the effort you put forth to learn the
concepts! Take notes, they will only assist you in learning the material!

From this page, click Monohybrid Cross, it will open the problem set page,
scroll down and click on the icon for Begin Problem Set, continue through the
problem set until you are finished. Feel free to review any problems as the
tutorial recommends, or as needed. Follow the same instructions for completing
the Dihybrid Cross problem set. The Vocabulary icon is linked to a
comprehensive list of terms used in the problem sets. Utilize thisfeature if
you have any questions!

In addition, you must create two additional questions for the problem sets.
One question should be suitable for the monohybrid cross problem set and the
second question should be an appropriate question for the dihybrid cross problem
set. These questions must be original and appropriate for the format of the
existing problem sets.

What to turn in:
Each student must turn in two, original, problems (one monohybrid cross, one
dihybrid cross).
Each student must turn in their notes/work page for the problem sets, with all
corrections.

Evaluation:
Students will be graded on the completeness of their work pages and originality
and appropriateness of their problem set questions.

Notes/Work Pages
Monohybrid Cross 10 pts
Dihybrid Cross 10 pts
Problem Set Questions
Monohybrid Cross 5 pts
Dihybrid Cross 5 pts
Total 30 pts

Conclusion: Students will develop comprehension of the complexities of
monohybrid and dihybrid crosses and apply their knowledge in problem
development. They will also be required to use basic skills in the
incorporation of technology.
