The methods and materials for teaching the vocabulary and writing components of an intensive summer English as a second language (ESL) program for foreign university students are described. Program goals are to improve English language proficiency and orient students to the American academic system and American culture. The approach to building vocabulary is systematic and intensive study of a core lexicon leading to vocabulary independence. Such exercises as word mazes, synonym and antonym matching, word association, and puzzles are used to help students acquire multiple shades of meaning, move words from the reading/listening to the reading/speaking vocabulary, and acquire independent learning skills that enable them to use their knowledge to decipher new words. The writing activities all consist of writing, obtaining feedback, and rewriting. The exercises include sentence combining and keeping journals. The daily schedule of activities for the 5-week course is described. (RW)
