Many topics within the middle school mathematics curriculum connect to the concept of proportion. Interpretation of proportion situations and understanding of methods for solving proportion problems provides a structure than can be applied to other related topics. As a major resource for secondary mathematics, the extent to which popular textbooks link proportion-related topics was the focus of this study. Our analysis revealed little connectivity of ideas, confusing definitions and frequently illogical calculations. Questions are raised as to the messages texts send to students.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
