ab: Summary: In this paper, we report on a comparison of the treatment of
addition and subtraction of fractions in primary mathematics textbooks
used in Cyprus, Ireland, and Taiwan. To this end, we use a framework
specifically developed to investigate the learning opportunities
afforded by the textbooks, particularly with respect to the
"presentation" of the content and the textbook "expectations" as
manifested in the associated tasks. We found several similarities and
differences among the textbooks regarding the topics included and their
sequencing, the constructs of fractions, the worked examples, the
cognitive demands of the tasks, and the types of responses required of
students. The findings emphasized the need to examine textbooks in
order to understand differences in instruction and achievement across
countries. Indeed, we postulate that within a given country there may
exist a recognizable "textbook signature." We also draw on the results
and the challenges inherent in our analysis to provide suggestions and
directions for future textbook analysis studies.
