Final answer:
The most effective teaching strategy for a diverse class is to individualize instruction to meet the varied needs of students from different cultural backgrounds and special-needs learners.
Step-by-step explanation:
The most effective approach to teaching in a class with students from different cultural backgrounds and special-needs learners would be to invest time in individualizing instruction, since no single strategy will likely meet all these needs. This approach acknowledges the unique contribution of each student and the necessity for teachers to understand their ways of thinking and communicating to provide equal education opportunities.
Additionally, it speaks to the importance of recognizing and addressing diversity, rather than adopting a 'color blind' perspective, which can perpetuate disparities in the educational system.
