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

Region:
Southeast
Abstract:

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:
Confirmatory
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.

Projected Release Date: Late 2020
