Step-by-step explanation:
Understanding Educational Practices for Mixed Abilities
The practice of a teacher putting students with mixed abilities and reading levels into one classroom is known as inclusive education. Inclusive education is part of efforts to provide universal access to education and to respect the rights outlined by legislations like the Individuals with Disabilities Education Act (IDEA). Under IDEA, students with disabilities should be mainstreamed with all students when possible, with the provision of necessary individual educational plans. While inclusion involves complete immersion of students with disabilities in standard classrooms, tracking refers to the formalized sorting system that places students on 'tracks' such as advanced or low achievers, perpetuating inequalities. To combat disparities in the education of students with disabilities, continuous research and debates focus on the optimal ways to include them in standard classroom settings.
