• Target audience: ELL (English Language Learners) students in grades 4-5 from Hispanic backgrounds • Tools: Snorkl - AI-based voice recording and feedback platform • Effects: Improved mathematical reasoning skills, improved English communication skills, increased math confidence • Methods: Structured problem-solving approach, scripting, peer feedback, repeated practice
Background on the introduction of Snorkl
Marcela Gomez, a teacher in Houston, Texas, found that her ELL students understood math concepts but had difficulty effectively explaining the process. Snorkl was introduced as a tool to bridge this gap.
Lesson structure using Snorkl
1.
Record your problem-solving process: Students voice-record themselves solving math problems step-by-step.
2.
AI Feedback: Snorkl provides instant feedback.
3.
Refine and Retry: Students refine their explanations based on feedback and re-record.
Effective Implementation Strategies
1.
Clear instructions: Encourage detailed explanations using the “as if explaining to a blind person” approach
2.
Structured response: Read the problem → Explain the situation → Explain the solution process → Provide an answer
3.
Scripting: Writing down your mathematical thinking process before recording.
4.
Peer Assessment: Students review scripts and exchange feedback with each other.
5.
Consistent practice: 45-minute Snorkl sessions twice a week
Notable achievements
1.
Improved mathematical reasoning skills: Students’ explanations of problem-solving processes become clearer and more logical.
2.
Improving English Language Skills: A Significant Number of Students Improve Their Scores on the TELPAS Test
3.
Increased math confidence: A significant increase in confidence, especially for students who previously struggled
4.
Increased motivation to learn: Students voluntarily request more practice with math problems
The educational value of Snorkl
1.
Personalized Feedback: Provides instant, personalized feedback through AI
2.
Integration of Language and Mathematics: Improving the ability to express mathematical thinking in language
3.
Promotes iterative learning: Provides opportunities for continuous improvement based on feedback
4.
Inclusive learning environments: Providing equal opportunities for expression for students from diverse backgrounds
This case study demonstrates the positive change that AI tools like Snorkl can bring to ELL students’ mathematics education. Simultaneous improvements in mathematical concept understanding and communication skills can contribute to students’ academic achievement and self-confidence in the long term.
