An important question about education is. then. why do some types of students achieve success easily and others struggle to do well? Well. One theory is that there is a genetic reason for academic achievement. What I mean by that is. a certain innate. measurable level of intelligence. Another frequently discussed theory is environmental factors. such as the effect of home and family upbringing. A final reason is related to the teaching and learning process within educational institutions. and the way it is organized, administered and assessed.
