|7 short reports of your choice
from among the 12 weekly assignments listed @ 9% each
|Preliminary facet question for thesaurus
(due March 12)
|Final thesaurus construction assignment
|Participation in online discussion lists
Grades on the traditional 15-point scale (-2 to 12, or F to A+)
will be assigned to each of the components of course work
worth more than 1%
(a pass/fail type grade will be assigned
to the preliminary facet question):
B- (7) for satisfactory work;
grades in the range of B (8) to A+ (12)
for various degrees above the satisfactory level;
grades in the range F (-2) to C+ (6)
for various degrees below the satisfactory level.
For the final mark,
an appropriately weighted average the grades will be computed,
and the result will then be translated into a percentage
to meet the requirements of the Faculty of Graduate Studies.
The usual short report will not be intended
to be a summary of everything that you have read or found out
about the week's topic.
Instead, it will lay the ground for online discussion
and provide a selective sample of your work
for evaluation and feedback purposes.
What is actually expected is indicated
in the "Weekly assignments and preparation" file
together with any additional special files.
Many assignments will emphasize thinking and problem solving
rather than the gathering of information from secondary sources.
Problems posed will not always have single correct solutions,
though some approaches will be more correct than others.
The assignment will form the basis for evaluating each report.
Criteria used in evaluating all reports will be correctness,
clarity of thought and presentation,
and coverage of all parts of the assignment.
Where the assignment requests a more extended discussion,
weight will also be given to the number of significant points
made within the length indicated.
You are reminded
that intentional duplication of another student's work
constitutes a violation of the policy on plagiarism.
Students must write their essays and assignments in their own words.
Whenever students take an idea
or a passage from another author,
they must acknowledge their debt
both by using quotation marks where appropriate
and by proper referencing such as footnotes or citations.
Plagiarism is a major academic offence
(see Scholastic Offence Policy in the Western Academic Calendar)."
Reports should normally be e-mailed to the instructor,
following the guidelines given at
Short reports will be evaluated
using a marking scheme
related to the wording of the particular assignment.
Confidential feedback will be provided by e-mail on each report.
This will always include the grade assigned.
will usually take the form of suggestions for improvement
Thesaurus construction project
For this project,

Details are provided in the files 677the.htm
A preliminary wording of the facet question
is due November 8.
The full project report is due
