Does Less Education Harm Health? Evidence From a Natural Experiment in a Developing Country
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT We investigate the health outcome effects of a reduction in years of schooling in Egypt in 1988, a policy change that moves in the opposite direction in relation to the extant literature. We exploit this policy change as a natural experiment and employ a fuzzy regression discontinuity design to investigate a range of objectively measured ...

Image of mathematics: A case study of two women's early mathematics experiences
School Science and Mathematics, EarlyView.Abstract People often view mathematics as abstract, cold, and irrelevant to real life, and their school experiences likely influence such views. In this case study, we investigated the mathematics experiences of two women who participated in an afterschool girls‐only STEM club 30 years ago when they were in fifth and sixth grades.

A mile high and an inch deep: Exploring ChatGPT as a mathematics curriculum development tool
School Science and Mathematics, EarlyView.Abstract Artificial Intelligence (AI) technology has issues, including inherent bias and inaccurate information, yet it has not stifled individuals' use of this technology in the mathematics classroom. Thus, we conducted a document analysis to investigate ChatGPT, a generative AI chatbot, constructing elementary mathematical tasks to determine how ...

Where Mathematical Symbols Come From
Topics in Cognitive Science, EarlyView.Abstract There is a sense in which the symbols used in mathematical expressions and formulas are arbitrary. After all, arithmetic would be no different if we would replace the symbols ‘+$+$’ or ‘8’ by different symbols. Nevertheless, the shape of many mathematical symbols is in fact well motivated in practice.
