In simplest terms literacy means being able to read and write. This is indeed the core of the educational process. The processes used to effect literacy in subject matter are extensive and well developed.
Intensive programs based on research in teaching and the learning process are ongoing.
These efforts are producing measurable, positive results in more effective teaching of subject matter. These efforts also enhance the ability to develop logical outlines, write tables of contents and indexes, construct business letters, write and use computer languages and many other forms of communication. The principles of effective communication are well known and are being further refined. These principles have not yet been extended to the writing, reading and solution of word problems. The effect is present across the curriculum, becoming particularly chaotic in physics.
