Course Description

Provides an opportunity to practice and work towards mastery of individually chosen topics from College Algebra (MTH 111). Completion of this course does not meet prerequisite requirements for other courses. Audit available.

Addendum to Course Description

This class is not intended to be a study hall for students to work on MTH assignments. The time
needs to be spent working on material designated by your ALM instructor. If a student is co-
enrolled in an MTH class, then this may include targeted materials which are intended to
support the concepts being taught in that MTH class.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Perform appropriate college algebra computations in a variety of situations with and without a calculator in a wide variety of settings.
  • Apply college algebra problem solving strategies in multiple contexts.
  • Address college algebra problems with increased confidence.
  • Demonstrate progression through mathematical learning objectives established between the student and instructor.

Course Activities and Design

Instructors may employ the use of worksheets, textbooks, online software, mini-lectures, and/or group work.

Outcome Assessment Strategies

Assessment shall include at least two of the following measures:

1. Active participation/effort

2. Personal program/portfolios

3. Individual student conference

4. Assignments

5. Pre/post evaluations

6. Tests/Quizzes

Course Content (Themes, Concepts, Issues and Skills)

Items from the course content may be chosen as appropriate for each student and some students may even work on content from other ALM courses as deemed appropriate by the instructor.

ADDENDUM

Documentation Standards for Mathematics: All work in this course will be evaluated for your ability to meet the following writing objectives as well as for "mathematical content."

  1. Every solution must be written in such a way that the question that was asked is clear simply by reading the submitted solution.
  2. Any table or graph that appears in the original problem must also appear somewhere in your solution.
  3. All graphs that appear in your solution must contain axis names and scales. All graphs must be accompanied by a figure number and caption. When the graph is referenced in your written work, the reference must be by figure number. Additionally, graphs for applied problems must have units on each axis and the explicit meaning of each axis must be self-apparent either by the axis names or by the figure caption.
  4. All tables that appear in your solution must have well defined column headings as well as an assigned table number accompanied by a brief caption (description). When the table is referenced in your written work, the reference must be by table number.
  5. A brief introduction to the problem is almost always appropriate.
  6. In applied problems, all variables and constants must be defined.
  7. If you used the graph or table feature of your calculator in the problem solving process, you must include the graph or table in your written solution.
  8. If you used some other non-trivial feature of your calculator (e.g. SOLVER), you must state this in your solution.
  9. All (relevant) information given in the problem must be stated somewhere in your solution.
  10. A sentence that orients the reader to the purpose of the mathematics should usually precede symbol pushing.
  11. Your conclusion shall not be encased in a box, but rather stated at the end of your solution in complete sentence form.
  12. Line up your equal signs vertically.
  13. If work is word-processed all mathematical symbols must be generated with a math equation editor.
