According to table 2, we can see that the meta-cognitive scores mean of chess player students was
more than non-chess players (as much as 7.19) and this suggests that chess play, as an independent
variable, has significant role in developing meta-cognitive ability of the students. In addition, the results
suggest that the difference was significant for meta-cognitive scores mean of chess player students at p <
0.01 (for fifth grade), p < 0.05 (for eighth grade) and p < 0.01 (for ninth grade) students when
compared with non-chess player students. The results summarised in table 3.
