A content analysis of topics relating to sex education as dealt with in five different postsecondary biology textbooks by different educational boards is made on a comparative basis. One finding is that the texts focus on facts rather than on social implications or utility. (Author/JN)

Asks the question, Can the learning cycle also be applied effectively to science text? High school students (n=23) were tested for reasoning ability then randomly assigned to read either a learning-cycle or traditional-text passage. Students who read the learning-cycle passage earned higher scores on concept comprehension questions at all…

Explores role of college textbooks in students' acquisition of special disciplinary literacy, focusing on use of metadiscourse as manifestation of writer's linguistic and rhetorical presence in a text.
