Data from the Effects of Congruent and Incongruent Perceptual Cues on Middle Schoolers' Mathematical Performance, Learning, and Retention Study.

This paper presents datasets for a research project that investigated the individual and combined effects of two perceptual cues-spacing and color-under varying conditions of congruence with the order of operations. The datasets contain 1,100 6th-grade students' data collected through a randomized controlled trial conducted in 2024 in a U.S. school district. All de-identified intervention data are openly available on the Open Science Framework. Additional datasets, including student demographics and assessment data, require a data sharing agreement. The data can be used by researchers interested in understanding perceptual learning mechanisms and improving online instructional materials for middle school mathematics.
