Final answer:
The general education teacher providing evidence-based instruction to all students in the class is utilizing Tier 1 of the RTI model.
Step-by-step explanation:
The RTI (Response to Intervention) model is used to provide interventions and support to students who are struggling academically. In the case described, where the general education teacher is providing evidence-based instruction to all students in the class, the teacher is implementing Tier 1 of the RTI model.
Tier 1 is the universal level of support that includes evidence-based instruction provided to all students in the general education classroom. This level of instruction is typically differentiated to meet the diverse needs of students in the class.
In Tier 1, the general education teacher uses research-based strategies and materials to teach the standard curriculum. The goal is to meet the needs of most students, but some additional support may still be provided to specific individuals or groups as needed.
