Supporting Teacher Enactment of the Probability and Statistics Standards (STEPSS)


Description: This study will investigate whether the STEPSS intervention increases students' conceptual understanding in statistics as compared with practice as usual through a randomized controlled trial. STEPSS includes two complementary components: four days of teacher professional development workshops in statistics, and implementation of 11 lessons designed to teach the grade 7 statistics and probability standards created by the American Statistical Association (Bridging the Gap and Statistics Education Web). STEPSS teachers will replace the current district-adopted textbook (HMH GO Math!) for the 20-day unit on statistics and probability with the 11-lesson unit. The study will use the Levels of Conceptual Understanding of Statistics (LOCUS) assessment to measure students' conceptual understanding in statistics.

Research Questions: The study will be guided by the following confirmatory and exploratory research questions:
RQ1. What is the effect of STEPSS on cognitive complexity and classroom discourse in grade 7 statistics instruction, as measured by the Instructional Quality Assessment (IQA)?
RQ2. What is the effect of STEPSS on grade 7 students' conceptual understanding in statistics, as measured by the LOCUS 30-item post-test?Exploratory
RQ3. What is the effect of STEPSS on grade 7 students' achievement in mathematics, as measured by the Florida Standards Assessment (FSA) Mathematics?

Study Design: The REL Southeast will randomly assign 40 middle schools in Broward to the grade 7 STEPSS intervention or the comparison condition (HMH GO Math!) during the 2018/19 school year. The sample will include approximately 160 teachers and 9,000 students within these 40 middle schools. Classroom instruction will be observed and fidelity of the STEPSS intervention noted.
