This is mine (successful) from 2001.

This is a scan because I wrote it in a totally awesome program called Page Maker which the fine folks at Adobe chose to discontinue for reasons nobody understands.

I mention this to point out that you should always print copies of important stuff because although digital files are fleeting, paper lasts forever.


Course Description: In the spring of 2014, Planetary Evolution will focus on extrasolar planets, which is an emerging area of research in planetary science. Students will use their knowledge of solar system astrophysical, geological, and geophysical processes to understand how extrasolar planets and systems different from our own might have formed and evolved, and how to place our solar system in context with those discovered so far. The emphasis of the course will be placed on the processes at work during the formation and evolution of planets and their systems rather than on individual planets or astronomical detection methods.

Meeting Times:

Tuesdays from 3:00 to 5:20 PM in Lincoln Field 105. First class meeting is on 1/28/2014.

Prerequisites:

Geol 1950G, or instructor permission, which will be granted to students who can demonstrate an understanding of the concepts presented in Geol 1950G.

Class Size:

Enrollment will be limited to ~15 students to allow each student taking the course for credit to give at least two presentations during the course of the semester.


Course Format

The class will meet in a two and a half-hour block once a week. Discussion topics will be explored through student-led discussions of relevant scientific papers. Each student will lead at least two discussions over the course of the semester. Short lectures from the instructor will supplement student presentations as needed.

Each class meeting will consist of: Two 35-minute talks from students, each followed by about 20 minutes of discussion; There will be one or two 5-minute coffee breaks during the class meeting.

At the first class meeting, students will be invited to suggest topics of their own choosing. However, to maintain balance in the course, I would like to spend ~four class periods discussing each of these three broad subject areas:


Grading

Talks:

On the weeks that you present and lead discussion, you will be evaluated on the presentation of material, facilitation of in-class discussion, and a 1-2 page written summary of critical points arising in the discussion. You will present and lead class discussion at least twice during the semester, with each discussion/presentation being worth 25% of the total grade. I will provide you with written feedback and a grade for your presentation and summary ~ 1 week after you present.

Your talk and summary (each worth a total of 100 points) with be evaluated on the following criteria:

At the class period BEFORE your presentation : Email to the professor the titles (and web links) for 1-2 papers that will be discussed in your presentation. These are the papers that the students will read in preparation for your talk. We will announce the titles of the papers for the following week at the end of each class meeting.

Prepare a 35 minute presentation on the topic, specifically addressing:

Final Project:

Over the course of the semester, you will prepare a research proposal on a theoretical study (includes modeling), laboratory measurements, observational campaign, or new instrumentation concept of your own choosing.

The proposal must be written in the format of a persuasive NASA NESSF or GSRP fellowship proposal, which is, per NASA policy: "no more than 6 single-spaced pages" in 12 point font, "with at least 1-inch margins on all sides." The 6-page limit does include figures, but, breaking with NASA policy, we will not include references in the 6-page limit.

Again, quoting NASA guidelines, "The research plan should be presented with a clear scientific hypothesis or question(s) to be addressed by the proposed work." The proposal should also address its relevance to NASA objectives. The proposal should also describe, in as much detail as possible, your proposed methodology, and demonstrate how that methodology can lead to a test of your central hypothesis.

Proposals will be evaluated on:

A one-page "Notice of Intent to Propose" will be due on March 11th. This should be a 250 word description of the basic idea in your proposal, your methodology, and the "category" of proposal (i.e., theory, laboratory, observational, instrumentation).

A one-page progress report will be due on April 15th.

Each of these is worth 5% of the course grade. I will only accept your proposal if the notice of intent and progress report are turned in. The final proposal is worth 25% of the course grade.

You will present the basic elements of your proposal in a persuasive talk in front of a panel of experts during the final class meeting. The final presentation is worth 5% of the course grade.

The remaining 10% of your grade is passed on in-class participation.
