Engelmann and colleagues developed three major writing programs: Expressive Writing, Reasoning and Writing and Essentials for Writing.
Engelmann and his colleagues’ first language programs were the DISTAR Language series, which they continued to revise over the following years and eventually renamed the programs as Language for Learning, Language for Thinking, and Language for Writing. The language programs’ many exercises in vocabulary, background knowledge, statement analysis, question, and concept application prepare students for the literal and inferential comprehension of the books and other materials they will read both in and out of school.
