Crossing the River with Dogs, Problem Solving for College Students (2nd Edition)
by Ken Johnson, Ted Herr, Judy Kysh  

A calculating device such as abacus, slide rule, log table, electronic calculator, computer etc.
A notebook and ruler.



Course Objectives: To train the mind to be analytical and provide a foundation for intelligent and precise thinking.
The goal is to:

  • become problem solvers who can recognize and solve routine problems readily and can find ways to reach a solution when no routine path is apparent.
  • communicate precisely about quantities, logical relationships, and unknown values with through the use of signs, symbols, models, graphs and mathematical terms.
  • reason mathematically by gathering data, analyzing evidence, and build arguments to support or refute hypotheses.
  • make connection among mathematical ideas and between mathematics and other disciplines.

Math 120 Student Learning Outcomes                                                      

  • A student will be able to employ both inductive and deductive reasoning appropriately.
  • A student will be able to construct visual representations of certain problems and then analyze those constructs to attain a solution.
  • A student will be able to identify patterns in observations presented in a problem and then predict other outcomes using the patterns they identified.
  • A student will be able to employ logic in solving a problem to arrive at a conclusion.
  • A student will be able to categorize given problems and then employ the correct procedures to solve the problems.

Grade: The possible grades in this course are A, B, C, D, or F. The cutoffs are as follow,

                                                         A ........ 90-100%
                                                         B ........ 80-89%

California Education Code Section 76224(a) states:
"When grades are given for any course of instruction taught in a community college district, the grade given to each student shall be the grade determined by the instructor of the course and the determination of the student's grade by the instructor, in the absence of mistake, fraud, bad faith, or incompetence, shall be final" (2004)

          Information/Registration Desk in the Tech Mall.

  1. All Supervised Tutoring courses are non-credit/non-fee. However, when a student registers for a supervised tutoring course, and has no other classes,  the student  will be charged the usual health fee.


Academic Integrity
Cheating and plagiarism (using as one’s own ideas, writings or materials of someone else without acknowledgement or permission) can result in any one of a variety of sanctions. Such penalties may range from an adjusted grade on the particular exam, paper, project, or assignment to a failing grade in the course. The instructor may also summarily suspend the student for the class meeting when the infraction occurs, as well as the following class meeting. For further clarification and information on these issues, please consult with your instructor or contact the office of the Assistant Dean of Student Affairs.
