Time to Transition: Financial Calculators and Clickers in the ClassroomThe compound interest tables are a primary teaching tool in the engineering economicsclassroom. These tables were created nearly a century ago as a time savings device whencalculations were done by hand. Over the past century, slide rules replaced much of thehand calculations, and scientific calculators replaced slide rules in the 1970s. Financialcalculators were introduced in the 1970s, personal computers were widely adopted in the1980s, and laptops became prevalent in the 1990s. Yet we still teach using compoundinterest tables as we did decades ago. The largest change has been the role ofspreadsheets.Similarly, within the last several decades we’ve added PowerPoint and on-line study aids,yet many of us have left the lecture relatively unchanged. The display may have shiftedfrom blackboards, to overhead transparencies, and to computer projectors; but the lecturestructure is often largely unchanged. The last decade has seen the deployment of lowcost student response units, and when used these “clickers” can radically change whathappens in a lecture period.This paper explores the advantages and disadvantages of using financial calculators andclickers in the classroom, along with some of the debate that has appeared in ourliterature over the past few years. The reasons for current views are explored, and severaloptions that have been tested in the classroom are described. We recommend that it istime for all of us to begin the transition away from reliance on tables, and use the modernelectronic tools that new engineers are expected to have already mastered while in school.
