Grading procedures

  1. The grades will be based on performance on a combination of lab and homework exercises, the two lecture exams, public presentations and written project reports.
  2. Part of the grade of the individual will involve critiques of presentations of your peers. Evaluation forms will be provided and a summary of the results returned to the student presenter.
  3. For the Pet Rock Project there will be an opportunity to revise the presentation and written report prior to the final submissions. This is an important part of that aspect of the process of learning to commucate effectively.
  4. For group projects a grade will be given to the group; i.e. all members of that group will receive the same score for that project.
  5. The breakdown of weighting of scores are:
    • Igneous lecture exam - 20%
    • Metamorphic (igneous) lecture exam - 20%
    • Igneous Project Report - 10%
    • Pet Rock Presentation and Report - 20%
    • Volcano presentations - 5%
    • Group lab reports and individual homework - 25%

Policy for late assignments: For each weekday (exclusive of vacation days) in which an assignment is late, 5% will be subtracted from the total score possible on the assignment. For example, if an assignment is two days late and the student received an 80% on the assignment, the score adjusted for late penalty will be 72% (i.e. 90% possible * 0.8).

Geology 3041 has been certified as a communication-intensive course at LSU with emphasis on writing and oral presentation. For more information on the LSU Communication across the Curriculum (CxC) initiative and the opportunity to attain a Distinguished Communicator distinction, refer to the CxC website.

----------------------------------------------------------------------------------------------------------------------------------

Overarching Learning Objectives for Geology 3041:

A student should be able to define, interpret, apply and analyze information and concepts related to the following topics:

  • identification and classification of igneous and metamorphic rocks in hand sample and thin section
  • textural evolution and its relation to formation history of igneous and metamorphic rocks
  • geochemical evidence for sources and evolution of igneous and metamorphic rocks
  • development of igneous and metamorphic rocks under a variety of tectonic environments

In addition, because this is a communications-intensive course, a student should be able to:

  • effectively communicate petrologic concepts and research in both oral and written forms
