Final answer:
The most effective school programs for English Language Learners involve ESL staff development programs that extend to the entire school staff. Research shows that students taught in both their native tongue and English make better progress than those taught only in English.
Step-by-step explanation:
The most effective school programs for English Language Learners include ESL staff development programs that:
- Extend not just to ESL teachers but to the entire school staff.
- Focus exclusively on ESL teachers.
- Exclude ESL teachers and target only mainstream teachers.
- Are limited to administrative staff only.
Research indicates that programs that extend ESL staff development to the entire school staff are the most effective. This is supported by studies conducted by Johns Hopkins University which found that students taught in both their native tongue and English make better progress than those taught only in English. Bilingual education programs, such as those that provide instruction in both English and Spanish, can help English Language Learners succeed academically.
