About the author
Donald Kiser is a language educator and curriculum designer with over fifteen years of experience teaching German to English-speaking learners. He holds a Master's degree in Germanic Linguistics from the University of Texas at Austin, where his research focused on second-language acquisition of morphosyntactic structures — specifically, how English speakers develop intuitions about German case marking and verb placement over time.
Kiser began his career as a teaching assistant at the University of Texas, where he designed supplemental grammar modules for first- and second-year German courses. Dissatisfied with the rote-memorization approach of existing textbooks, he developed a set of explanatory materials that prioritized structural logic over pattern drills. These materials formed the initial basis for what later became *German Grammar Unlocked*.
From 2014 to 2020, Kiser taught at the Goethe-Institut in Munich, where he worked with learners from over forty countries and observed firsthand the patterns of difficulty that recur across linguistic backgrounds. He noticed that English speakers faced a distinctive set of challenges — not just with cases and genders, but with conceptualizing a language where grammatical relationships are signaled through inflection rather than word order. His teaching during this period emphasized contrastive analysis: showing English speakers exactly where their native language would lead them astray and why.
Kiser has contributed to curriculum development projects for the German Academic Exchange Service (DAAD) and served as a consultant for digital language learning platforms designing adaptive grammar exercises. He has given workshops at the annual conference of the American Association of Teachers of German (AATG) on topics including teaching the case system without memorization, using input flooding for passive voice acquisition, and designing effective grammar diagnostics for intermediate learners.
He currently lives in Berlin, where he continues to teach, write, and develop open-source language learning materials. His current project is a companion volume focusing on German vocabulary acquisition through etymological pattern recognition, scheduled for publication in 2027.
