Students who are not native speakers of English can receive early drafts of Railsback's Powerpoint lecture files, so that they can become familiar with new words before attending the lecture. Students wishing to take advantage of this opportunity should send an email message to Railsback (firstname.lastname@example.org).
Selected Powerpoint lecture files are now available on eLCnew. However, no other functions of eLCnew will be used for Railsback's GEOL 3030 course. Email messages sent to Railsback via eLCnew will not be received. Send email to him at email@example.com..edu.
The availability of these Powerpoint files in no way indicates that attendance in lecture is unimportant, nor that one can do well in the course without coming to lecture. Exams in Railsback's GEOL 3030 course will continue to examine material covered in lecture, including thoughts discussed in response to student questions. These Powerpoint files are therefore not an adequate resource in preparing for exams.
Syllabi are now available for the 9:30-10:45 lecture and the 3:30-4:45 lecture.
Some histograms of grades from previous exams are shown below. There is also a page showing course grade distributions, as well as exam grade distributions, of previous years' classes.
Persons withdrawing before the midterm withdrawal deadline will be given WPs, not WFs.
