INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original subm itted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target” for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

However, there are special individuals who deserve the undying gratitude of this author because without their professional, moral and often very personal support, this dissertation would have never become a r e a l i t y . Special gratitude must first be extended to Dr. Jerry A. Wallin, Chairman of my Ph.D. committee. The time and professional advice that Dr. Wallin provided me was critical in the completion of this project. But my gratitude to Dr. Wallin goes far beyond that of simply a profes­ sional relationship. If it were not for his uncanny ability to motivate and to provide encouragement during those times when the odds looked overwhelmingly negative, this dissertation may have never been com­ pleted. It is these characteristics that make Dr. Wallin, in my opinion, a true credit to his profession. I would also like to thank Dr. 0. Jeff Harris and Dr. Andy Deseran for their diligent assistance while serving as members of my reading committee. Their suggestions were invaluable in improving the q u a lity of th is d is s e rta tio n , and th e ir comments were always provided in a timely manner indicating their true concern for the student. Special thanks must be extended to Dr. Michael H. Peters. Although not a member of my committee, Dr. Peters willingly gave a i i i i i great deal of his time to insure that the statistical analysis performed in this study was correct® I would also like to extend my thanks to my fellow graduate stu d en ts, Mr. Danny W orrell, Mr. W illiam Sharbrough, Mr. Bill McCartney, and Mr. Alev Efendiouglu for their help in con­ ducting my experiment. I also wish to thank Dr. Raymond V. Lesikar and Dr. Leon C. Megginson who served as members of my committee. From a very personal standpoint, I would like to express my deepest gratitude to my wife's parents, Mr. and Mrs. Tom Garner. The inspiration that they provided me to continue my schooling and to pursue my dreams regardless of the odds cannot be expressed in words. School has taught me a great deal about my profession, but they have taught me that the pursuit of happiness is the only quest which u lti­ mately has any meaning. Finally, I must extend to my wife, Jean, a gratitude which only she can understand. She has provided me with support and encouragement everyday for three years. She has given me many hours of technical assistance which were invaluable to the quality of this dissertation. But my gratitude for her goes far beyond this. Her love has given me the emotional stability to challenge new worlds without fear. She has instilled in me a confidence in my own ability, and a desire to prove that I have something to offer. Without her this dissertation, this degree, and this life would be insurmountable obstacles rather than enjoyable challenges. I love you Jean.

Last year’s ASEE Annual Conference was a success by almost any measure, and all of us—ASEE staff, leaders, volunteers, and you, our attendees—contributed to a great meeting. We are confident that this year’s event will be even better. Whether attending in person or on a computer, one thing remains the same, and that’s the tremendous amount of great content that ASEE’s Annual Conference unfailingly delivers. From our fantastic plenary speakers, paper presentations, and technical sessions to our inspiring lineup of Distinguished Lectures and panel discussions, you will have many learning opportunities and take-aways. I hope you enjoy this week’s events and please feel free to “find” me and reach out with any questions or comments! Sincerely, SHERYL SORBY ASEE President 2020-2021 2 Schedule subject to change.
