Methods Of Instruction

The course will employ a variety of instructional methods to accomplish its objectives, including some of the following:  lecture, labs, field work, analysis and interpretation of graphs, maps and air photos, slides, videos, individual and/or team projects and small group discussions.

Course Description
Have you wondered how mountains form or why earthquakes and volcanoes occur where they do? Have you ever picked up a rock and wondered where it came from? Geography 1120 addresses these questions with both theoretical and interactive hands-on instruction in the origins of the Earth’s land surface and its modification by tectonic and surface processes. Topics include: minerals and rocks, geological time, weathering and soils, and the processes and landforms associated with fluvial, glacial, coastal and desert systems. Human impacts on each of these systems are also examined.

Learning Outcomes

At the conclusion of the course the successful student will be able to:

  1. Describe and use the frameworks of science applicable to first-year physical geography.
  2. Analyze and interpret minerals, rocks, sediment and soils to identify their environment of origin.
  3. Describe and explain the processes that occur within earth’s lithosphere and hydrosphere, as well as their interactions with the atmosphere.
  4. Think critically and examine geomorphological issues in a scientific context at local, regional and global scales.
  5. Communicate effectively using the language, graphical presentation methods and quantitative methods employed in physical geography.

Means of Assessment

The evaluation will be based on course objectives and will be carried out in accordance with Douglas College policy.  The instructor will provide a written course outline with specific evaluation criteria during the first week of classes.

Evaluation will include some of the following:

  • Laboratory assignments with a combined value of up to 50%.
  • Multiple choice and short answer exams with a combined value of up to 50%.
  • Field work with a value of up to 20%.
  • A term project with a value of up to 25%.

 

An example of a possible evaluation scheme would be:

Laboratory Assignments  10%
Two Laboratory Exams  30%
Midterm Examination  25%
Final Examination  25%
Term Project  10%
Total 100%

Note:  This course received a standing variance from Education Council in November 1999 to allow up to a 15% open book lab exam in the penultimate week of the semester.  This is not a final exam; it is an assessment of student learning of lab work performed in the second half of the semester.

Textbook Materials

Texts will be updated periodically. Typical examples are:

  • Christopherson, R. W.  and Byrne, M.L. (2006). Geosystems: An Introduction to Physical Geography (Canadian ed.).  Toronto: Prentice Hall.
