The Beginning Level texts and workbooks are the first of a four- level series (Beginning 1 and 2, Intermediate 1 and 2, Advanced Intermediate, and Advanced) developed collaboratively by leading classroom teachers and linguists of Korean. All series volumes have been developed in accordance with performance-based principles and methodology-learner-centeredness, contextualization, use of authentic materials, function/task-orientedness, balance between skill getting and skill using, and integration of speaking, listening, reading, writing, and culture. Grammar points are systematically introduced with simple but adequate explanations and abundant examples, exercises, and drills.
