Final answer:
The best practice for demonstrating that all students can learn and achieve is to provide varied and integrated opportunities for engaging with the curriculum.
Step-by-step explanation:
The practice that best reflects a teacher’s commitment to the belief that all students are capable of learning and achieving academic success is providing students with opportunities to address curricular content from integrated and varied perspectives. This approach encourages a heterogeneous classroom environment where each student’s individual learning style and pace are considered and where collaborative learning is promoted. In contrast to a one-size-fits-all teaching method and a rigid grading system, offering differentiated instruction and a variety of assessment types, including formative assessments and performance tasks, ensure that each student has the chance to engage with the material in a way that is best suited to their needs and abilities.
Increasingly intensive instructional interventions for struggling students and a flexible grading system are also indicative of a teacher’s commitment to all students’ success. However, these do not necessarily involve tailoring the classroom content and approach to leverage the strengths of each student as does addressing content from various perspectives. Displaying examples of student work is somewhat reflective of this commitment. Still, by only showcasing excellence, it may not represent the progress and efforts of all students, especially those who may be achieving personal milestones at different academic levels.
