'Engineering Economics Jeopardy!' Mobile App for University Students

摘要

This article presents the Engineering Economics Jeopardy! mobile app development process and college students' satisfaction assessment of the developed app. The app includes a general tools E-book, calculator, reference tables, conceptual questions, and calculation problems in an engaging fashion. The E-book is a summary of the key concepts of engineering economics. The calculator provides functions to solve basic engineering economics problems with formulas. The tables allow the users to compute discrete compound interest factors. Through this Jeopardy! game, users can compete with two virtual opponents that have artificial intelligence to answer conceptual questions and calculation problems. Different sets of problems range from the simple questions on the time value of money to more complex concepts, such as sensitivity analysis, Monte Carlo simulation, and supply-demand equilibrium. This app is intended to give students more opportunity to learn and practice concepts of engineering economics whenever and wherever they want using their mobile devices. Accomplishments of this work include the following:Engineering Economics Jeopardy! mobile app has been developed and distributed.Five thousand people have downloaded the app so far.The effectiveness of the developed app has been researched with 116 college students who were enrolled in engineering economics courses across two semesters.
