This is a page to provide links for topics
relevant to the course and to post updates
to the course syllabus and course schedule.
Final exams for fall 2016 have been graded, and the grades have reported to the UGA Registrar. The distribution of course grades is available from the GEOL 1122 page showing course grade distributions, as well as exam grade distributions, of previous years' classes
Exam II has been graded. It will be or was returned on Tuesday, October 20, 2015, at the end of class. The histogram below shows the distribution of grades.
Selected Powerpoint lecture files are now available on eLCnew. However, no other functions of eLCnew will be used for Railsback's GEOL 1122 course. Email messages sent to Railsback via eLCnew will not be received. Send email to him at email@example.com.
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 1122 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.
The following is a grading rubric to guide determination of the GEOL 1122 participation grade arising from recounting of creation stories:
i. Student coherently recounts the story, to the story's end, in no more than 120 seconds: 100%
ii. Student recounts much of the story but does not reach the story's end in 120 seconds, or gives an incoherent presentation of the story that reaches the story's end: 60%
iii. Student reports that he or she is unprepared to recount the story: 20%
iv. Student is not present, or tries to recount the story but gets through only little of the story, or gives a strikingly incoherent or inappropriate recounting of the story: 0%
With regard to the Academic Honesty Policy of University of Georgia, if a student is called upon and is given notes or text by another student, this will be treated the same as sharing answers on an exam, which would be a violation of that policy.
Part iii is included so that the everyone can avoid Part iv.
Railsback has been excused from jury duty for the rest of the week (and presumably the semester), and so the course will proceed according to the original schedule on the syllabus and in the tabular "Schedule for Railsback's GEOL 1122 for Fall 2015" below. Thus on Tuesday, September 1, we will cover "Goals and Theories" and Creation Story 21.
Bruce Railsback has been summoned for jury duty on the week of August 31, so that he may or may not be unavailable Tuesday, September 1, and/or Thursday, September 3. The result is that TA Doug John may have to give one or both lectures that week. The lecture that was scheduled for Tuesday, September 1, is one that only Railsback can give, so some changes to the schedule may occur, as shown in the scenarios below. The upshot is that lecture topics for a given day may change, but creation stories remained fixed to particular days: CS 21 on Tuesday, September 1, CS 6 on Thursday, September 3, and CS 7 on Tuesday, September 8.
Scenario 1: Railsback is not required to be in the courthouse on either Tuesday or Thursday, and so no change in schedule is required.These scenarios change the topics of lectures given on certain days, but the creation stories assigned to those calendar days remain the same: CS 21 on Tuesday, September 1, CS 6 on Thursday, September 3, and CS 7 on Tuesday, September 8.
Scenario 2: Railsback is required to be in the courthouse on Tuesday, September 1. Doug will give Lecture 6 ("Working Through Time"), originally scheduled for Thursday, and Railsback will give Lecture 5 ("Goals and Theories") on Thursday, September 3.
Scenario 3: Railsback is free to lecture on Tuesday but is required to be in the courthouse on Thursday, September 3. If so, Doug will give Lecture 6 ("Working Through Time") on Thursday as expected from the course schedule.
Scenario 4: Railsback is required to be in the courthouse on both Tuesday, September 1, and Thursday, September 3. If that happens, Doug will give Lecture 6 ("Working Through Time") on Tuesday, September 1, and he will give Lecture 7 ("Correlative and Relative Dating") on Thursday, September 3, and Railsback will give Lecture 5 on Tuesday, September 8.
This webpage is now updated for Fall 2015. The syllabus is now available as a pdf file.
Very old news:
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.
If the distinction between WP and WF is relevant, persons withdrawing before the midterm withdrawal deadline will be given WPs, not WFs.
