Textbooks for the teaching of algebra in lower secondary school: are they informed by research?

Over the past 30 years, there has been a great deal of work directed at, first, understanding students' difficulties in algebra and, second, examining ways of tackling these difficulties. There is a vast research literature detailing successful ways of teaching algebra in experimental and laboratory settings. Yet, there is no clear evidence that this work has had a significant effect in terms of improving either attainment or engagement in algebra in ordinary, or non-experimental, classroom settings. Indeed, in England, current attainment in algebra appears to be no better than that of 30 years ago. In this paper, we analyse the algebra topics from two textbooks currently in widespread use in England, focusing on Grade 7 (ages 12-13). We examine the extent to which these textbooks draw on the research literature to support the teaching of algebra. Finally, we discuss the implications of this study. [ABSTRACT FROM AUTHOR]
