Formal vs. informal mathematics: Assessing numeracy with school and market items in a large sample of school-aged children in North-West Nigeria
While school-aged children in resource-poor settings often perform poorly on standardized tests in mathematics, they can frequently be seen engaging in market activities, conducting monetary transactions. This suggests that children in these settings actually have much more advanced skills in basic mathematics than what is assessed at school. For this study, we designed a learning assessment that captures a broader skill set, including tasks presented as formal and informal mathematics. We provide evidence of a considerable skill gap between formal mathematics and informal mathematics in a large sample of school-aged children in North-West Nigeria. We explore several potential explanations for this skill gap. Market engagement is positively associated with the ability to solve the informal tasks but not formal tasks.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
