At the beginning of each quarter, students in my advanced computer classes create a time card for themselves. Each day students record their attendance just as one would at a job. Each class period counts four hours. On Fridays this information is transferred to a spreadsheet representing a payroll register. Formulas are put into the payroll register to calculate total hours for the week, gross pay, deductions, and net pay. Since part-time workers receive no benefits, there is no pay for snow days, school vacation, sick days, doctor's appointments, etc. There is also a deduction of � hour for tardiness. At the end of the quarter, students who have earned the most pay receive valuable bonus points. Students quickly learn that being late or absent does not 'pay'.
