Al's bandwagon part of Dilemmas
In the eight person seminar class is an inquisitive, nontraditional, student who is a motivated popular science reader. This student challenges the conclusions made by the vocal majority of scientists that global warming is caused by human activity.

Avoiding hopeless paralysis part of Dilemmas
In an intro class, I wanted to engage students and show them the importance of the field of geology in their lives. So I presented the evidence for an imminent peak in world oil production and explained how oil forms, how long that takes and how difficult it is to find. I followed the bad news with some good news about research into energy efficiency and alternative energy sources. I assigned the students to write minute-papers at the end of class about this lecture.

Too Cool for Science part of Dilemmas
On a frigid Minnesota afternoon, I had just finished a mini-lecture in my introductory class, and I threw out a question to the whole class. Chris responded enthusiastically with a wonderful and correct contribution. At which point, Sam groaned and said, in a voice audible to the entire class,"suck up!" A few other eyes rolled, and other hands that had been raised were slowly lowered.

The Legacy of "We've always done it this way" part of Dilemmas
Joe recently completed his PhD and has landed a tenure track faculty position in the geology department at "Research U" for the fall semester. Joe will be teaching a large introduction to physical geology course in the spring. Research U has a variety of resources to help Joe develop his course and integrate the "affective domain," active learning, "clickers," etc. into his teaching. However, the department has a strong emphasis on research and views innovative teaching as not a priority. While in graduate school, Joe TAed both lower level introductory lectures and an upper level lab class, but received no formal training in teaching and was encouraged by his research advisor "just get by teaching."

Karl the Tree Hugger part of Dilemmas
Karl has been assigned to you as an advisee, and you have never met him and have no information on him other than what the registrar shares. He is obviously smart (he received a "5" on the AP Environmental Science exam). He has made an appointment with you to discuss a program of study.

Is planetary change bad? part of Dilemmas
We hear about global warming as a problem and there is a reasonable consensus that humans are exacerbating the problem. Our global population is currently about 6 billion, and scientists estimate that the planet's capacity to sustain ends at about 12 to 15 billion. Doubling time is 38 years. Next examine the core profile. Tundra pollen lies in the lowest layers, sage and prairie grasses in the middle and spruce and pine pollen in the top.

Convincing faculty about the importance of the affective domain part of Dilemmas
Professors may believe they are "only there to teach" and the students are "there to learn," and it is not the professor's responsibility to worry about motivating them or making them feel good about learning. Possibly, students don't have the ability to succeed, so why should a professor try to motivate students who have a stronger potential to fail?

Working for big oil part of Dilemmas
A student has already completed several courses in geology and is seriously considering majoring comes to you with the following personal dilemma. The student has realized that the most lucrative employment opportunities are with major oil and mining industries. However, she doesn't want to put herself in a position of working for one of the "bad guys."

Pissed about Pluto—The nature of science and how we teach it part of Dilemmas
Sarah is a student in a science class for teachers. The class started working on a scale model of the solar system and when we got to the topic of Pluto, Sarah was distraught that Pluto had been "plutoed." During elementary school Sarah had done a report on Pluto that included creating a model of the planet, for which she received much positive feedback.

Transforming Attitudes and Killing Interest in Introductory Geology Classes for Majors part of Dilemmas
Students enter Physical Geology with great interest in geology regardless of declared major or academic rank. Approximately 70% of students (n=306) declared a high level of interest in multiple aspects of geosciences. However, at the end of the semester, less than 30% of the same population recorded a high interest in geology (regardless of declared major, academic rank).
