Research Question Which determinants of a modified Theory of Planned behavior are most important in predicting pro-environmental behavioral intentions in undergraduates?<br>
04
Survey Development Four environmental behaviors<br>
05
Survey Development Theory of Planned Behavior (Ajzen, 1991)
Attitude: I think recycling is important Behavior<br>
06
Survey Development Theory of Planned Behavior (Ajzen, 1991)
Subjective norms: People who are important to me expect me to recycle. Behavior<br>
07
Survey Development Theory of Planned Behavior (Ajzen, 1991)
PBC: If I wanted, I could recycle during the next 6 months. Behavior<br>
08
Survey Development Values-Beliefs-Norms (Stern et al. 1999)
Biospheric values: Respecting the Earth: Harmony with other species Behavior Ecological Worldview<br>
09
Survey Development Values-Beliefs-Norms (Stern et al. 1999)
Egoistic values: Wealth: Material possessions, money Behavior Ecological Worldview<br>

Survey Development Knowledge of Climate Change
1. How has the amount of carbon dioxide in the atmosphere changed since the start of the Industrial Revolution 150 years ago?
A. The amount of carbon dioxide has remained the same.
B. The amount of carbon dioxide has decreased.
C. The amount of carbon dioxide has increased.
D. I do not know.<br>
12
Perceived Behavioral Control Biospheric Values Egoistic Values Attitudes Subjective Norms Personal Norms Knowledge Behavioral Intentions<br>
13
Survey Dissemination Undergraduate students in general education science labs
Fall 2016-Spring 2017
n=132<br>
Highlighting Norms Group work around climate behaviors
Increased subjective norms
Activating personal norms
Consequences and responsibility<br>
21
Conclusions Norms inform public sphere environmental behavior
Knowledge does not impact these behaviors
Students need opportunities to explore values, norms, and behaviors around socioscientific issues<br>

Survey Development Seven Independent Variables
Dependent Variable: Behavioral Intentions Attitude: I think recycling is important
Subjective Norm: People who are important to me expect me to recycle.
Personal Norm: I feel a strong moral obligation to recycle.
Perceived Behavioral Control: If I wanted, I could recycle during the next 6 months. Biospheric Values: Respecting the Earth: Harmony with other species
Egoistic Values: Wealth: Material possessions, money Climate Change Understanding: 5 knowledge questions I intend to, always or in most instances, recycle in the next 6 months.<br>
