Quantitative literacy has been identified as a critical skill necessary for statistical thinking and effective citizenship. The purpose of this study was to evaluate an instrument for determining the use of reform-oriented instructional practices that promote quantitative literacy. Data were collected from 160 US college instructors of developmental mathematics. Items in the scale were developed from a set of 10 criteria previously identified as essential for fostering quantitative reasoning and problem-solving ability. An acceptable level of reliability was obtained, and criterion validity was established in relation to instructors' beliefs, specifically perceived usefulness and personal teaching efficacy. A significantly higher level of use of all practices was reported by instructors with a degree or concentration in statistics (versus mathematics). These findings can help to inform professional development programs. Further research is needed to examine the psychometric properties of this scale.
