I apologize for sending this earlier in MIME. Here it is again in plain
text. Sorry for the double posting.

I wrote a literature review last year on text comprehension of health
education materials, and posted some of the information to the listserv in
May, 2001.  I apologize in advance for its length.

Here is what I found:
Optimally, our goal should be to make a better match between reader and
text.  Reading comprehension is an interactive process that involves the
reader, the author, and text.

The reader brings her reading ability, prior knowledge, purpose for reading
(interest and motivation to read) into the equation.  Strategies for reading
are also important.

The author adds the purpose and intended audience, information to include,
and language that facilitates reading and understanding of the text.

Textual variables help the reader make connections within the text, and
influence the way the text is interpreted.  These features include
structure, content, cohesion, and how the letters and words are placed on
the page. When text construction facilitates the readers' acquisition of
information, it is known as "considerate text." (Armbruster, 1994).

The cohesion of text aids the reader in building coherent representations of
information and meaning construction on a local (word-by-word) and global
(construction of meaning from the text as a whole) level.

Rhetorical relationships play an important role in content structure (Meyer,
1985), and help the reader make associations within the text at a global
level (Goldman & Rakestraw, 2000).  they include syntactic rules, questions
and summaries, signaling devices (font size and change, paragraph
indentations, numbered lists and bullets, underlining, text boxes,
illustrations, charts, tables and graphic representations).

The purposes of expository text, such as patient information, are to
persuade, explain, and inform.  The most important aspect of the text is
that it be  a good match with the reader's prior knowledge, skills,
interests, learning goals, and culture.  Unfortunately, much expository text
makes in correct assumptions about the reader, and fails to provide adequate
information and explicit links to help the reader make meaning of the text
(Beck et al, 1998).  Content density and readability are issues here. Klare
(1984) states, "merely shortening words and sentences to improve readability
is like holding a lighted match under a thermostat when you want to make the
room warmer."  Instead, writers should focus less on readability formulas
and other restrictive devices and more on conceptual content, creating a
better match between reader and text.
