Reports released by the What Works Clearinghouse (WWC) this week review the existing research on two programs: Investigations in Number, Data, and Space® and LANGUAGE!®.
Investigations in Number, Data, and Space® is an activity-based K–5 math curriculum designed to help students understand number and operations, geometry, data, measurement, and early algebra. Based on the research evidence, the WWC found Investigations in Number, Data, and Space® to have potentially positive effects on mathematics achievement for elementary school students. To read the full WWC report, go to http://ies.ed.gov/ncee/wwc/interventionreport.aspx?sid=242.
LANGUAGE!® is a language arts intervention designed for struggling learners in grades 3–12 who score below the 40th percentile on standardized literacy tests. The WWC found that LANGUAGE!® has no discernible effects on reading fluency or comprehension for adolescent readers. Learn more at http://ies.ed.gov/ncee/wwc/interventionreport.aspx?sid=621.
