At AEON, adult students are placed in classes according to their speaking ability. High school and university students are placed in classes with adult students, since they have already received English education in public schools and possess general knowledge of the language. The courses for adult students consist of the following types of lessons: Each Roundup lesson contains both a fundamental section which emphasizes basic grammar usage and rules and an enhancement section which expands upon the basic communication exercises. The purpose of the Roundup lessons is to bring students to the stage where they can use the correct form and natural expressions in conversation. Group lessons are designed to encourage less structured or less academic-sounding conversation in practical situations. Dialogue practice in pairs or small groups is the main activity in these lessons. Whereas Roundup lessons focus on particular grammatical or structural weaknesses the students may have, Group lessons focus on functional aspects of the English language. Private lessons focus on the individual needs of one student. Once these needs are determined, the teacher, along with the student, designs a lesson plan to achieve specific goals. Since the lessons are tailored to each student, they can learn at their own pace. Due to the personalization of these lessons, the student's progress is rapid. AEON offers preparation courses for English proficiency examinations, such as the TOEFL test, the TOEIC test, and the STEP test. If the need arises, we also open courses to prepare high school students for their university examinations. There are also other courses to improve students' specific language skills, for example vocabulary, listening, pronunciation or grammar courses.
