      GEOL 1122 - Historical Geology

This page was last updated on Sunday, November 6, 2016, to add a new item to the section of “GEOL 1122 webpages ”.

Previously, on Thursday, November 3, this page was changed to correct the course schedule regarding the date of Lecture 27. The linked syllabi were corrected as well. No due dates or exam dates were changed.

Course news:

Exam 2 has been graded and was handed back at the end of class on Thursday, October 13, 2016.

Old News:

Syllabi are now available for the 2016 9:30-10:45 lecture and the 2016 3:30-4:45 lecture.

 

 

Final exams for fall 2015 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.

Exam I has been graded.  It will be or was returned on Tuesday, September 22, 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 rlsbk@gly.uga.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 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.

 

 

 

If the distinction between WP and WF is relevant, persons withdrawing before the midterm withdrawal deadline will be given WPs, not WFs.
