To help community college reading teachers be aware of the connectives (conjunctions that join other words, phrases, clauses, or sentences) used in textbooks, a study was undertaken to find out which connectives appeared in a sample of 18 textbooks and which were used in the textbooks for three different subject areas--social science, physical science, and allied health fields. Twenty-three of the connectives chosen for the study were single words or phrases, and the twenty-fourth, a collective term labelled "list," referred to words joining a series of items such as "first" or "second." For each book, the total number of all-print pages was counted. Twenty percent of these were read and each occurrence of connectives was listed, then multiplied by the number of pages. After the tabulation of the connectives, the totals were added to the frequency of usage of the connectives. The word "as" was used most often, and the word "unless" was used least often. The connectives were then categorized and the usage of each category in each type of textbook was tallied. The results showed that different types of connectives were used in different textbooks, but the clarification and contrast connectives (for example, thus, as, such as, but, however, although, yet) were found most often in all three types of books and the condition connectives (if, whether, even though, unless) seemed to be used least often.
