Second, what are the relationships between the keywords of the learning competencies that low-achieving college students perceive to have improved through the board game design and development process? For this study, reflective journals from 97 low-achieving college students who participated in the board game design and development process were analyzed. Specifically, keywords related to the learning competency improvement were derived, and the relationships between these keywords were analyzed. The findings are as follows First, low-achieving college students perceived that their collaboration skills improved the most through the experience of participating in the board game design and development process, followed by problem-solving skills, communication skills, learning transfer, and interaction skills.
