Does Student Access to Solution Manual Pose a Challenge?AbstractMany modern engineering textbooks include problem examples with detailed solutions ineach chapter. The purpose of the examples is to help students with a better understandingof the theory and their application in engineering. At the end of each chapter thetextbooks provide a large number of problems for homework assignments. The purposeof homework assignments is to provide students with experience in solving problemswithout having access to the solution. One aim of homework assignments is to preparestudents for engineering employment where they are routinely required to solve problemsthey have not seen before. In addition to excellent problems in the textbooks, almost allpublishers provide solution manuals as a resource for instructors. These manual givesdetailed solutions for each problem included in the text book. Many are prepared in typeset with excellent graphics. In more recent years these solution manuals are provided indigital format. We have noticed that in the past few years many students have access tothe digital copy of the solution manuals. A Google search for solution manuals for anytextbook gives a list of sources where the solution manuals can be obtained. Examplesare e-bay or CrAmster.com. We have also noticed that the percentage of unsuccessfulattempts to pass the course (grades of D, F, and W) sharply increases when students haveaccess to the solution manual in the course. Even those who pass the course have a hardertime in follow up courses. To remedy this challenge, we have adopted new proceduresfor assigning homework problems and assessing student knowledge. This papercompares grade distribution in thermodynamic courses when the students had access tothe solution manual with those when most students completed their homeworkassignments without the aid of the solution manual. It will describe our new approach inassigning homework problems and assessing student learning outcome.
