Overview

Course Description
This course enables students to develop their ability to reason by introducing them to elements of formal reasoning. The primary focus will be on recognizing the logical structure of arguments. Topics will include types of statements, symbolism, logical connectives, logical relations, basic deductive inferences, truth tables, validity, invalidity, and soundness; and may include, in addition, inductive reasoning and the testing of scientific hypotheses. Emphasis will be upon acquiring a basic working knowledge of propositional and predicate logic.

    Methods Of Instruction

    The course will employ a variety of instructional methods to accomplish its objectives, including some of the following:

    There will be two hours of lectures each week, with time allowed for questions; there will also be two hours of discussion of the exercises and assignments.  Emphasis will be upon obtaining a working knowledge of most of the topics covered

    Means of Assessment

    Evaluation will be based upon 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 at the beginning of the semester.

     

    Any possible combination of the following which equals 100%:

    (No one evaluation component within each category may exceed 40%)


      

        Percent Range                    Examples
    Midterm tests     20% - 60% Two 20% tests         40%
    Quizzes and short assignments        0% - 40% Ten 2% quizzes       20%
    Final exam    20% - 40% Final exam              30%
    Instructor's general evaluation
    (may include attendance, class participation,   
    group work, homework, etc.)
         0% - 20% Attendance/
    participation            10%
    Total                               100%
    Learning Outcomes

    Successful students will be able to:

    1. Distinguish the basic elements of arguments and recognize the different types of arguments.
    2. Symbolize natural language statements in the language of propositional and predicate logic.
    3. Identify logical relations among statements; and analyze logically complex statements into their truth- functional or quantificational components.
    4. Distinguish valid deductive arguments from invalid ones.
    5. Use truth tables and formal proofs to analyze the logic of arguments and to assess their adequacy.

    This course will include some synchronous on-line activities. Students should plan to be available on-line at scheduled course times. Synchronous on-line activities may include lecture, or they may not. In some courses, synchronous class time may be used instead for active learning components ((e.g. discussions, labs).
