Literature Review
Long time ago Ballard (1915) has stated that “Another factor unfavorable to
progress is the non-recognition of the essential heterogeneity of a
collection of children… If they appear like one another today, they will
appear unlike one another tomorrow.” It is the composite and complex
structure of our world that continuously generates the heterogeneity
among any community of learners providing them with different
experiences and reflections. A critical factor in the success of any
education process is the wise utilization of this diversity to provide quality
teaching.
