A study of dual-language elementary classrooms found that students who received instruction in two languages performed at or above grade level in both languages by fifth grade, despite initially showing slower progress in each language compared to single-language peers. Cognitive testing revealed that dual-language students also scored higher on tasks measuring mental flexibility and attention control.
Which conclusion most logically follows from the passage?
- A
Dual-language programs primarily benefit students who already speak both languages at home
- B
Single-language instruction produces better long-term academic outcomes
- Ccheck_circle
Initial slower progress in dual-language settings does not necessarily predict weaker eventual performance
- D
Mental flexibility cannot be developed through other educational methods
Explanation
Slower start but at-or-above-grade outcomes support B. A contradicts the findings; C and D are unsupported by the text.
