Fixation on grades part of Dilemmas
Each semester our university offers several large-enrollment (n ~ 220) sections of a lecture-based introductory physical geology course. Although the course can be counted toward a geological sciences major, it functions mostly as a service course that provides non-major students a science credit necessary for graduation.

Field Trip Anxiety part of Dilemmas
A few years into teaching my physical geology course, I made a bold move and added an all-day, mandatory field trip to the course. With 120 students in the course, orchestrating this field trip was neither an easy nor inexpensive task. I used the field trip as a major milestone of the course, talking it up for weeks beforehand, and structuring the lectures, labs and homework assignments to lead up to the Big Day. I am usually a pretty enthusiastic teacher, and my own excitement for the upcoming field trip was enough to make most of the students roll their eyes.

Recruiting Under-represented Minorities into a Geoscience Program part of Dilemmas
Students of under-represented groups have little to no interest in the Svalbard REU program. Despite concerted recruitment efforts, members of under-represented groups often don't apply to the program. We use direct mailings (with recruitment posters) and presentations, advertisement at national meetings with minimal success. We can not seem to be able to place this paid opportunity on their "radar-screen."

Meteorology Professor Bob part of Dilemmas
In an upper-level meteorology class, Meteorology Professor Bob introduces complex equations including calculus. A growing body of students strongly resist using mathematical skills that should have been mastered in the prerequisite mathematics courses. The instructor explains the context and necessity of these equations for understanding meteorology at the upper-division level. A common statement of students is: "I don't do math." Students insist they love meteorology but dislike math and lobby the department head for a graphical approach without the use of equations.

Mineralogy Motivation - A Real-Life Tale of Woe part of Dilemmas
I teach mineralogy (do you feel my pain?). Mineralogy has a reputation for being a "weed out" course, and not very many students look forward to taking this class. But in addition, in our department I've encountered another problem: we have a degree option in paleontology, and students who self-select this option basically want to be Jack Horner and head out to the hills to dig up dinosaur bones.

Gender Dynamics part of Dilemmas
A Geosciences program and classes has few to no female students in them. One female faculty wants to expand the diversity of the program. She then teaches an introductory course to increase enrollment of female students. This course however is full of students who hold the following attitudes:

Scientific uncertainty and global warming part of Dilemmas
Climate change is the major environmental issue facing all inhabitants of spaceship Earth. As Earth science educators, we must inform students about the scientific consensus on global warming and projections of future warming through this century. Recent research has resulted in a dramatic advance in our understanding of climate history.

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."

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.

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?
