ATTENTION STUDENTS

 

 

You will learn to use the 10-key adding machine by touch while reviewing basic math with business applications. 

  1. You must attend an Orientation before beginning the course.
  1. Read the introduction and follow the course outline to meet the course requirements.
  1. You must attend four hours per week in the Center plus one hour of lab TBA.
  1. CAO 178ABC is a three unit course that requires at least 48 hours to complete.

Textbook:  SOLVING BUSINESS PROBLEMS ON THE ELECTRONIC CALCULATOR, 6th ed., by Polisky; Glencoe Publishing Co., 2003.

Course Content:         (Each module = 1 unit of credit.)

         Module A -        Technique and operation of ten-key electronic calculator and computer 10-key pad.  Develop speed and accuracy doing touch addition, subtraction, multiplication, division, rounding, and estimating without a calculator.  Using constants and negatives.

          Module B -        Using ten-key electronic calculator to do common business problems with emphasis on speed and accuracy.  Continue speed building on touch addition.  Use memory, fractions, decimals, percents, discounts, work with invoices, markup, markdown, and payroll. 

         Module C -        Do more business problems.  Continue speed and accuracy building on touch addition.  Use stocks, bonds, investments, and interest rates. 

Advisory:        Math 187B or equivalent course. 

Student Outcomes:
Using a ten-key electronic calculator, student will be able to:
do touch addition at 100-120 keystrokes per minute or more, and
solve business problems commonly found in business offices using the features of a ten-key electronic calculator.

Methods of Evaluation:

1.     Teacher observation of skill and timed drills.
           Touch addition speed goals:
           140 KSPM (keystrokes per minute)   = A
           120 KSPM                                        = B
           100 KSPM                                        = C 

         2.  Quality and quantity of projects completed.        

         3.  Tests.

         4.   Course Grade:                                                        Overall Grading Scale:
25% = touch addition speed                                                A = 90 - 100%
30% = textbook projects                                                     B = 80 - 89%
45% = tests                                                                         C = 70 - 79%
                                                                                           D = 60 - 69%
                                                                                           F = 0 - 59%

 Attendance:  Regular attendance is expected.  A skill is built and developed through daily practice.  The class assignments will require you to attend five hours per week.  For better than average achievement, you will need to spend extra time in the lab practicing your skill.  If you cannot attend class, please notify me by leaving a message in my voice mailbox.  If you are absent for two weeks with no message, you may be dropped from the class.

 Assignments: 

       See assignment schedule below. 

Lab Hours:

       In addition to the four hours spent in the Center, you may wish to use the lab and machines for additional practice in the D120 lab.  A schedule of available lab hours is posted in Room D120.  Please log in all lab hours you spend in Room D120 on the computer "timekeeper."  The lab instructor in Room D120 can help you.

Math Help:

       If you need help in math, see the math tutor in the Math Department. 

Accommodations:

Any students needing accommodations should inform the instructor. Students with disabilities who may need accommodations for this class are encouraged to notify the instructor and contact the Disability Resource Center (DRC) early in the quarter so that reasonable accommodations may be implemented as soon as possible.  Students may contact the DRC by visiting the Center (located in room A205) or by phoning 541-4660, ext. 249 (voice) or 542-1870 (TTY for deaf students).  All information will remain confidential.

Weekly Timings:

       Please see your instructor in week two for an orientation on “How to Take Keystroke Timings” (pg. 10 of syllabus).  You will need to record your best KSPM per week on the chart below.

How to Take Keystroke Timings

 

Starting in week two, you will be taking weekly timed drills to determine your keystrokes per minute (KSPM).  You will be taking three 3’ timings and then choosing the best score to be recorded.  Please talk to your instructor to get a drill sheet and timing device.  TIMINGS MUST BE TAKEN DURING CENTER HOURS.

Steps for completing keystroke timings: 

1.                  Get drill sheet, KSPM Form, and timing device from your instructor.  Set your decimal selector at two.

2.                  Take three 3’ timings. 

3.                  Proof your tapes against the drill sheets and circle any errors.  Each incorrect digit counts as one error, for example:

*  28 instead of 82 is two errors

*  102 instead of 103 is one error

*  entering a wrong number and then immediately correcting it by subtracting the number is considered one error.  (Example:  18.59+ followed by 18.59- followed by 18.58+)

*  duplicate entry is one error. 

4.         Calculate gross keystrokes per minute:

Use the small numbers on the drill sheet, adding any keystrokes beyond small number to get exact numbers of keystrokes. 

*  Decimal point is not counted as a keystroke.

Each time the add bar is used counts as one keystroke:

4.06 is four keystrokes (the numbers 406 plus use of add bar)

406 is four keystrokes for the same reason

*  Each time the total bar is used counts as one keystroke.

An                     example of gross keystrokes per minute:

KS = 25 + 6 + 5

GKS= 36

 

 

 5.        Calculate KSPM 

a.       take the total gross keystrokes, then

b.   subtract errors circled (this total is the net keystrokes), then

Text Box: Gross KS                                36
- Errors                            -      1
Net KS                                   35
Divide by 3 (# of minutes)    )     3
KSPM                                     11.67

            c.   divide net keystrokes by 3 (minutes)


 

6.         Fill out the purple KSPM Form, attach tapes to form, and turn in to the INBOX in the D120
            classroom.
