Teaching Mathematics and Science Standards to Students With Moderate and Severe Developmental Disabilities

This study evaluated strategies to teach secondary math and science content to students with moderate and severe developmental disabilities in a quasiexperimental group design with special education teachers randomly assigned to either the math or the science treatment group. Teachers in the math group implemented four math units representing four of the five national math standards. The science teachers implemented four science units representing three of eight national science content standards. A fourth standard, science as inquiry, was embedded within each of the units. Results showed students made gains in respective content areas. Students who received instruction in math scored higher than students who received instruction in science on the posttest of math skills. Likewise, students who received instruction in science scored higher than students who received instruction in math on the posttest of science vocabulary skills. Limitations and suggestions for future research and practice are discussed
