This document provides an overview of strategies used in an intensive English program course to incorporate English for Specific Purposes (ESP) principles into multidisciplinary academic English courses. The course utilized student-led needs analyses, field-specific text analysis, document formatting aligned with individual fields, and ESP-adapted presentation assignments. Examples of assignments include having students interview professors in their fields, analyze language features in field-specific articles, learn citation styles of their disciplines, and give presentations defining vocabulary terms or discussing issues from their areas of study. The document demonstrates how ESP principles can make such multidisciplinary courses more relevant to students' academic needs.
