I designed a vocabulary learning system for high school seniors preparing for university entrance exams, starting with weekly classroom worksheets and evolving into a formal workbook series used across multiple courses at LNK Academy. The project addressed a persistent learning challenge: students’ difficulty distinguishing visually similar or semantically related words. The system includes two coordinated formats: • MIX & MATCH — A puzzle-based workbook that emphasizes word differentiation through matching, contrast sets, and pattern recognition. • EXP-BOOK (Expression Book) — A sentence-focused workbook that helps students internalize vocabulary through contextual usage, translation tasks, and example-driven composition. Each workbook integrates progress-check sections for teaching assistants to review, enabling structured feedback and targeted support. Content is updated annually based on recent exam trends and newly introduced vocabulary, allowing the material to stay pedagogically relevant and appropriately challenging. This project reflects an iterative, classroom-driven design process where instructional materials moved from ad-hoc worksheets to a scaled curriculum artifact adopted by multiple instructors.
