      GEOL 1122 - Historical Geology

This page was last updated on Wednesday, May 20, 2020, to add course news.

 

Course news:

GEOL 1122 will be taught in Fall 2020, either in person (as announced by UGA President Jere Morehead on April 29) and/or via eLC (if the situation evolves away from an on-campus model).  Seven learning resources will be available to all students:
>> Live lectures in Room 200A GG, to the extent possible per UGA policies that may evolve through time.
>> Students' lecture notes from those lectures.
>>
Lecture summaries (a 68 MB download) specific to this course.
>> Powerpoint recordings of lectures, including all slides and voiced presentation, available via eLC.
>> The textbook for which optional (not required) reading assignments are shown below and on the syllabus.
>> Optional meetings via Zoom for students to ask questions, discuss course content, etc.
>> Email with the professor at rlsbk@uga.edu).

Old news from Fall 2019:

Final exams for Fall 2019 have been graded, course grades have been reported to the registrar, and the distribution of course grades is now shown on the page of past grade distributions.

Roughly forty extra-credit essays were submitted between 7:00 pm Monday 2 December and the deadline 11:00 am Tuesday 3 December 2019. All of them arrived so shortly before the deadline that students' correction and re-submission was not feasible (whereas resubmission had been easy for submissions that began in late September and had continued across the subsequent two months). Those two facts meant that submissions received after 7:00 pm Monday 2 December were not marked with the detail or formality with which earlier submissions were marked, and most were instead only given marks of "+3" or "+0" and were not returned.
      Many of the errors in submissions were those about which warnings had been posted on the web page about the assignment.

The Powerpoint file linked for Lecture 26 has been updated with better sound.

Three of 134 students took advantage of the opportunity described below for a lab visit to see research of the sort on which this course depends.

Rather than a field trip, Railsback's GEOL 1122 offers an optional (not required) lab visit in which students see stalagmites used in paleoclimate research and see some of the equipment used to sample the stalagmites.  The lab is in Room 202 GG, across the hall from our lectures in Room 200A GG.   Four times for visits are available: 8:45-9:15 am and 12:20-12:50 pm on November 7, 2019, and November 12, 2019.   The 12:20-12:50 opportunity can be expanded to see the mass spectrometer in the Department of Geology's Stable Isotope Laboratory too.   A one-page introduction to stalagmite-based paleo-environmental research is available at /FQS/FQSStalagmitesAsRecords01.jpg.

Exam II for Section 35645 meeting from 9:30 am to 10:45 am has been graded and will be or was handed back on Thursday 17 October 2019. A histogram of the grades appears below.

The Scientific Literature Exercise has been graded. The average score for the 106 students who submitted the exercise before the time it was due was 95.4 (and 52 students of those 106 received a score of 100). The average score for all 139 students (including the 12 who submitted it late and the 21 who submitted nothing) was 76.9.

In the 11:00-12:15 section Tuesday 3 September 2019, we did not have time to discuss Creation Story 7. We will sadly have to let it pass and move on to Creation Story #3 on Thursday 5 September 2019. This has no relevance to the 9:30-10:45 section.

The page linked as "Questions asked frequently or recently by 1122 students, and the answers to those questions " has been updated.

Railsback again promises to be in Room 200A Tuesday (27 August) morning from 8:30 to 9:15 to answer questions about the Scientific Literature Exercise.

It seems that students in Section 13799 meeting from 11:00 am to 12:15 pm received an email message on the evening of 22 August 2019 offering the note-taking services of a commercial entity external to the University System of Georgia. This message was not sent by the instructor, the person sending the message was not authorized by the instructor to send a message via eLC, and the instructor in no way endorses the use of any note-taking service. Students should not use eLC as means to send messages on behalf of organizations or commercial entities, because such messages are violations of the University's campus solicitation policy.

The course schedule below has been revised, with a column added so that there are separate columns of dates for the 9:30-10:45 section and for the 11:00-12:15 section. Students in the 9:30-10:45 section can access a new Page 6 of the syllabus.

Syllabi are now available for Section 35645 meeting 9:30-10:45 Tuesdays and Thursdays and Section 13799 meeting 11:00-12:15 Tuesdays and Thursdays in Fall 2019.

Exercise 1, the Scientific Literature Exercise, is due at 5:00:00 pm on 27 August 2019. A link to the exercise appears below.

Students are hereby alerted that GEOL 1122 lectures will be audio-recorded, and thus that things said in Room 200A may be recorded. The recording process is only intended to establish a record of the lecture for possible administrative or legal processes against the lecturer, and it is expected and hoped that the recordings will never be listened to at all.

Ancient news from Fall 2018:

Exam 2 has been graded and will be or was scheduled for hand-back on Thursday 11 October 2018 at the end of class. Histograms of the grades appear below.

GEOL 1122 students are reminded that assigned readings on the course webpage are part of the material from which exam questions may come. For example, Question 13 of the 2017 Exam 1 came from the What is Science reading linked with Lecture 5.

Grades on the 2018 Scientific Literature Exercise for the 9:30-10:45 section were
100: 17 students     95: 4    90: 3     85: 1     80: 1     0: 4

Grades on the 2018 Scientific Literature Exercise for the 11:00-12:15 section were
100: 32 students     95: 4    90: 6     75: 1     0: 13

Links to blank copies of last year's exams now appear below. These blank versions can be used as practice exams to which students have the keys to check their work.

Syllabi are now available for the 2019 9:30-10:45 lecture and the 2019 11:00-12:15 lecture.

*Notes regarding readings:
    All readings are in Stanley and Luczaj's Earth System History (4th edn), except for linked web pages and for numbers labeled "CS", which are numbers for stories in Creation Stories from around the World.
    Pages in brackets are suggested reading that may make lecture material easier to understand.
    Reading assignments do not include "Earth System Shift" ("ESS") inserts unless specifically noted.
    Reading assignments include all figures to which reference is made, even if the figures fall outside the page range indicated.

Additional GEOL 1122 policies:

Powerpoint files of illustrations used in lecture, but not lecture outlines, will be 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: 0%

v. Student 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 v.

 

 

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

 

 

GEOL 1122 lectures will be audio-recorded, and thus that things said in Room 200A may be recorded. The recording process is only intended to establish a record of the lecture for possible administrative or legal processes against the lecturer, and it is expected and hoped that the recordings will never be listened to at all.
