A new study done by the Higher Education Quality Council of Ontario （HEQCO） shows that it doesn't make much of a difference that parents reward their children with cash for their better marks.

Many parents have offered cash to their children in the hope that it would improve marks and possibly raise their children's interest in achieving higher marks．

The study, conducted by researchers from the University of Toronto （UT） and the Massachusetts Institute of Technology （MIT） to learn more about the potential for financial encouragement as motivation for improved marks, involved first and second year students receiving financial aid in 2008-2009 at the University of Toronto Scarborough．

The top students participating in the study who said they were "very concerned" about having enough money to complete their degrees were to receive $100 for getting a grade of 70 per cent for each one-semester course, plus $20 for every percentage point beyond that．It was imaginable that a student could earn as much as $700 for achieving 100 percent in a course．

Harvey Weingarten, president and CEO of HEQCO said, "In its efforts to help disadvantaged students by exploring the idea of paying them to attend school, the Toronto District School Board （TDSB） is asking the same question many other districts are asking about how to improve student participation and performance．Our study and others to date indicate that this practice has little effect if any in those situations where it has been tested．"

The authors of the study suggest that ineffective study habits may be a barrier to academic achievement and that the real problem may be more a lack of academic preparation than a lack of effort or motivation．They note that the availability of peer （同伴） advising does not appear to have helped greatly．They conclude that other potential avenues to improving performance, or other approaches of teaching, are needed at the high school and postsecondary levels．
