Abstract: Current engineering classroom environments and the contemporary teaching and learning usually employ textbook materials and supplementary reading. Currently, textbook material’s checklists and evaluations are not popular in most of the Asian educational environments and societies. The purpose of this study is to employ the Dos Santos’s textbook materials evaluation checklist to evaluate an English as a Foreign language textbook at a South Korean University, particularly for a textbook for engineering students who tend to enhance their English language skills. The research study collected data information from both classroom teachers and students who have already completed the English language course with the textbook. The result provided a directive guideline for potential readers, university administrators, teachers, students and industrial employers evaluate their textbook and training materials with a useful checklist.
