Controversial Issues in a Secondary
Science Classroom

2. Introduction
• Biotechnology is
constantly advancing
• The need to discuss
controversial topics in
the secondary science
classroom is increasing
• Controversial issues can
be uncomfortable or
awkward for students
and teachers
4. Questions
• Should controversial topics become a larger
part of the science curriculum?
• Are some topics too controversial for the
middle/high school classroom?
• What is the best method to teach
controversial topics?
• Do teachers and students from different
science content areas have different opinions?
5. Literature Review Common Themes
• Mixed Methods- Qualitative &
Quantitative (written survey and
interview)
• Similar Questions
• Open Ended Questions
• Similar Teaching Methods- Debate
• Variety of Teachers
(grades, experience, etc)
• Controversial Topics
• Teachers Only
6. Literature Review Differences
• Varied Sample Sizes (n=6-317)
• Varied Degrees of Teaching Experience
• Demographic Differences (UK, US)
• Questionnaire Differences
• Analysis of Results
7. Appendix A -Sadler et al.
Interview Protocol
1. (a). What roles do values play in science? (b). How are ethics involved in science?
2. (Given positive answers to #1) Describe a specific case or issue in which values and/or
ethics contribute to science?
3. What are some value-laden issues within your discipline?
4. (a). Ideally, how should values and ethics be handled in the science classroom? (b) How
do you deal with values and ethics in your classroom?
5. What are some specific incidents during which values and/or ethics were addressed in
your classroom? Describe what happened.
6. Some science educators suggest that controversial scientific issues such as cloning and
gene therapy should be made an important part of the science curriculum. What do you
think about this suggestion? What are the strengths of this proposal? What are some
problems that might result from this approach? To what extent should science teachers
highlight the moral and ethical components of scientific issues in their classrooms?
7. (If elaboration has not been offered) How might you convince colleagues that dealing
with ethics and values in the classroom is central to science education?
8. How do you handle your own values relative to issues discussed in the classroom? Do
you have a right to express your opinions and beliefs?

9. Appendix: Likert Evolution Learning Experience Items
1. Evolution should not be taught in high school biology.
2. I like learning about evolution in class.
3. My biology teacher thinks students should learn about
evolution in high school biology.
4. Most people in my family think evolution is true.
5. My biology teacher does not think evolution is true.
6. In biology class, we did labs about evolution.
7. In biology class, we watched movies about evolution.
8. We mostly learned about evolution when my teacher
lectured about it.
9. Evolution came up in many class discussions in biology
class.
10. I had chances to talk about my personal views on evolution
in biology class.
Note: Response categories: strongly agree, agree, disagree,
and strongly disagree.
10. Proposed Study
• Survey & Interview Middle/High
School Science Teachers and Students
about their opinion on controversial
topics in the science classroom
• Determine whether more time needs
to be spent on controversial topics
and what the best methods are to
teach those topics
• Determine if there are differences in
opinion across different science
content areas and grade levels
