Why STELAR Coach?
Teachers need timely feedback to develop the instructional competencies needed to teach multilingual children successfully.
timely
Feedback is delivered soon after recording, when it is most useful for teacher reflection.
personalized
Feedback is based on the teacher’s own recorded interaction — not a generic example or outside observation.
simple & actionable
Reports are organized into
My STELAR Moments, My Missed Moments, and Action Steps.
evidence-based
Grounded in research on multilingual language development, interaction quality, and early learning.
Teacher-driven
Designed for teacher reflection and instructional decision-making — not outside evaluation.
What STELAR Measures
Feedback focuses on four core domains that build knowledge, concepts, English, and home language skills.
1. Word Knowledge
2. Meaning and Comprehension
3. Child Language Production
4. Home Language Bridging
Why Teacher Talk Matters
Classroom talk shapes how multilingual children build knowledge, develop concepts, and gain the language and learning skills needed for academic success.
Through everyday teacher–child conversations, children build English while continuing to develop their home language. The way teachers prompt thinking, ask questions, introduce new words, sustain back-and-forth exchanges, and connect home languages to new learning shapes what children learn — and what they carry into kindergarten and beyond.
