CLS congratulates its most recent PhD recipient, Warat “Pomm” Khaewratana.
Dr. Khaewratana successfully completed his dissertation, “Word games for education: Investigating the effectiveness of adding elaboration tasks to crosswords for learning technical vocabulary,” in May 2022.
Receiving a Royal Thai Scholarship to study in the United States, Pomm set out to help resolve the problem regarding a lack of skilled laborers in Thailand’s workforce. His motivation was to create effective and innovative workers with knowledge in the latest technology and skills obtained through specialized training and curriculum. He began his graduate studies at Rochester Institute of Technology (RIT), New York, and earned the degree Master of Science in Manufacturing and Mechanical Systems Integration before arriving at Michigan Tech.
Pomm was accepted to the Applied Cognitive Science and Human Factors (ACSHF) PhD program in Fall 2018. He focused his doctoral research on the challenge in STEM education to not only memorize technical terms but learn and remember how to apply them in practice. He examined the gaming technique of crossword puzzles combined with strategies to enhance memory for training technical information. See dissertation abstract below for more information regarding this research.
Abstract: One challenge in STEM education is the learning of technical terms. In order to reason about higher-order scientific concepts, knowledge of technical vocabulary is often a prerequisite. Improving the knowledge may enhance learning of higher-order concepts because it reduces cognitive load students experience while learning. To that end, we need innovative learning-aid tools that help students not only in learning and remembering technical terms but also in applying the learned knowledge in broader concepts. This dissertation investigates the hypothesis that learning gain from crossword solving can be used to teach technical terms. Furthermore, I am also examining the hypothesis that an additional elaboration technique will enhance the effect of the crossword puzzle. In a series of seven experiments, I investigated the effect of crossword with add-on elaboration on students’ ability to retain memory of learned technical terms and to provide more in-depth explanations of those terms. Across experiments, I investigated (a) three different types of elaboration technique, (b) collaboration vs. individual participation, (c) in-person vs. online training, and (d) short vs. long delay. Across experimental variations, results indicated that using a crossword alone produced a statistically significant learning effect relative to a control condition. Although adding structured elaboration did provide benefits when added to crossword-based study, the results were mixed where additional time was given to crossword, and different elaboration techniques did not provide specific enhancement on memory retention. Implications for theoretical perspectives on learning technical vocabulary and best practices to implement crossword in educational settings are discussed.
Pomm will join Rajamangala University of Technology Lanna in Chiang Mai, Thailand as a teaching professor as part of the Royal Thai Government fully-funded international scholarship agreement.
Pomm says the best memory of his time at Michigan Tech were all the group activities provided by Graduate Student Government (GSG), CLS department socials, and other university events. “I was able to try new things that I may not have gotten the chance to do on my own. Or if I did, it would not have been the same as experiencing it with others,” he explains.
He also gave special thanks to his Co-advisors Elizabeth (Beth) Veinott and Shane Mueller, committee members (Shari Stockero, Amanda Gonczi, and Qian Zhang), colleagues, CLS staff, and chair Kelly Steelman. In closing, Pomm stated “I am who I am now because of them. Graduate student life can be very challenging. These people have helped me to succeed and prepare for my future.”
Special shout out to colleagues Isaac and Stephanie Flint, Thomas Offer-Westort, Kaitlyn Roose, Anne Linja, Lamia Alam, and Shruti Amre.
