The body of research examining students' graphing understandings across STEM fields indicates students are not developing productive meanings for graphs.

This study aimed to contribute to the science of vignette design by developing and evaluating vignettes for measuring vision in rural China. Cognitive interviews were conducted among 36 participants in a Chinese middle school. The respondents either directly evaluated vision…

In this research, we examined overall performance and gender differences in measurement skills in elementary-school students from low-income families. In Study 1, accuracy and error patterns were analyzed in a large sample of fourth-graders; in Study 2 error patterns and strategy usage were examined with a smaller sample of fourth-graders. Study 1…
