Is there global

and if
so, because of
humans?
1)
From what you have read and heard, is there solid evidence that the average
temperature of the earth has been getting warmer over the past few decades?
(Yes/No/I Don’t Know) – Directly from PEW survey
2)
If yes, then:
a) Mostly due to human activities such as burning fossil fuels
b) Mostly because of natural patterns in the earth’s environment
c) Don’t know
Climate Change Refresher
Objectives For This Research
Teaching Goal:
In order to understand how to teach climate change more
effectively, I need to know what opinions students have about
climate change coming into the course and what factors may be
influencing their opinions.
Objectives:
a) determine what influences student’s incoming opinions
about climate change
b) evaluate the effectiveness of passive vs. active learning
strategies in shaping post-course opinions about climate
change.
Methods - Surveys
- Surveys were given to two environmental science courses for nonmajors:
a) FW 203 Resource Ecology (class I taught Spring semester)
b) ISP 217 Water and the Environment
- An initial 15 question survey asked for student opinions on climate
change and what sources of information had the most influence
- A follow-up survey at the end of the semester asked the same
questions, but also included questions on science educational
background, opinions about science and scientists, and a brief
assessment of scientific literacy.
Methods - Surveys
Example survey questions:
- From what you have read and heard, is there solid evidence that the average
temperature of the earth has been getting warmer over the past few decades?
(Yes/No/I Don’t Know)
If yes, then:
a) Mostly due to human activities such as burning fossil fuels
b) Mostly because of natural patterns in the earth’s environment
c) Don’t know
- Rate on a scale from 1-5, how much influence each of the following sources
had on your opinion about climate change before taking this course
(1 = very influential, 5 = non influential)
a) What I’ve learned from previous classes
b) Opinions of friends and family…..
f) What I’ve seen from watching the news

Students taking these courses already have a higher acceptance rate of human-induced
global warming coming into the course than adults in the PEW survey.

Specific associations between climate change opinions and a number of co-factors
including, measures of scientific literacy, science background and opinions about
scientists, are still being analyzed.

The follow-up survey indicated that acceptance rates of human-induced global warming
increased to nearly 90% in the FW203 course and 71% in the ISP course.

Next Steps and Implications
 Analyze specific associations between climate change opinions and co-factors
including: measures of scientific literacy, science background and opinions
about scientists
- A preliminary analysis indicates that students appear less likely to
accept climate change if they don’t believe there is a consensus among
scientists.
 Emphasize hard-data in lectures and perhaps tie this into active learning
activities such as analyzing a CO2 or temperature data set from multiple
observatories.
