This study sought to find out if (a) the performance of 113 Jamaican 11th-graders on a mole concept test was satisfactory or not; (b) if there were significant differences in their performance linked to their chemical and mathematical abilities, gender and socio-economic background; and (c) if there were significant relationship among the four independent variables and their performance on the test. The participants, comprising 66 boys and 47 girls, were selected from three traditional high schools in Kingston, Jamaica. Nine structured questions were used to assess their performance. The result revealed that the students' performance was unsatisfactory as their mean score (10.65 or 23. 67 %) was far below the conventional 50 % pass mark; there were significant differences in their performance based on their chemical and mathematical abilities in favour of students with high abilities in both case; and, there was a positive, statistically significant and 'substantially reliable' correlation (Miller, 1991) between the students' chemical abilities and test performance ( r = .58, p< .001), mathematical abilities and performance (r = .56, p < .001) all in favour of students with high abilities in each case, while the correlation between their (a) gender and performance ( r = .37, p < .01), and (b) SEB and performance ( r = .27, p < .01) was positive, statistically significant but weak in each case.....
