The document discusses using culturally responsive teaching and gifted differentiation strategies to raise mathematical achievement among diverse learners. It notes the underrepresentation of African Americans in gifted programs and issues with standardized tests. The research question asks if these teaching methods can increase math achievement. The proposed study would use a quasi-experimental design to compare math scores of 6th grade students taught with these strategies to those not receiving such instruction. Limitations include not observing subgroup differences and confusion around research assumptions.
