Inhalt: "Hi! Korean" is a series of integrated Korean coursebooks created for foreign learners who have started studying Korean because they like Korean culture. The contents of these textbooks include the latest trends in Korean culture, and various activities are presented so that learners can master the 4 areas of language; speaking, listening, reading, and writing. The composition of the series is consistent from the beginner level to advanced, with speaking, listening, reading, and writing presented organically, and listening and reading presented separately by unit, organized to increase concentration of learning in each area. In particular, in the “Step Up!” section, which moves away from activities centered on simply answering questions, learners can develop their communication skills by expanding on what they learned through speaking and writing activities. The “Hi! Korean” series is comprised of 10 Student's Books (4 beginner, 4 intermediate, and 2 advanced) and an additional "Grammar and Vocabulary Study Book," as well as 10 Workbooks (4 beginner, 4 intermediate, and 2 advanced), which are sold separately. "Hi! Korean 2A" is the first level 2 book of the series, designed for learners to start studying Korean in earnest after finishing level 1. It allows for learners to study level 2 grammar and vocabulary expressions within the themes of Korean society and culture. In particular, by studying expressions related to public service that are encountered in school life, learners can become able to use these expressions appropriately in real life.
