Students continue to develop and refine their proficiency in all four language skills: listening, speaking, reading and writing, with emphasis on the ability to interact orally and in writing. They communicate using more complex language structures on a variety of topics, moving from concrete to more abstract concepts. At this level, students comprehend the main ideas of the authentic materials that they read and hear, and they are able to identify significant details when the topics are familiar. Students gain a deeper understanding of the world around them while studying rights and responsibilities, future plans and choices, teen culture, the environment and humanities. Some familiar themes and topics from levels I and II may reoccur in level III. However, the spiral nature of the theme-based instruction requires students to demonstrate their communicative skills and linguistic sophistication at a new developmental level.
