from the graphs, we can see that grades have been rising rapidly. it can well be said that there is a grade inflatiou. take, for example, the stone mountain jr. college. in the fall semester of 1968, 16% of the students taking the exams received as. however, in 1978, within ten years, the percentage went up by 13%. twenty nine percent of the students received as. as for the b grade studems, in 1968, the percentage was 31%. ten years later, the percentage dropped to 26%. there was a 5% decrease, or rather, the students grades rose by 5 %. now let us have a look at the third graph, which shows that in 1968 37% of the examinees received cs while in 1978 the ratio fell to 21%. in other words, there was a 16% rise in grades.and in the forth graph, we can see that 8% of the students received ds. in 1978 only 4% of the examinees are d grade students. that means the grades doubled within ten years as compared to that of 1968. the grade inflation puts me upon thinking whether students are working harder than ever or the teachers are being. lenient or cheating is on the rise. i hope for the beat. |
