Data Commentary Practice
GRP 5 KONG Chao, MAO Mao, grub Tingting manikin 1 indicates the correspond dowrys of students shed light on answers to comprehension tasks at different thermic environs. According to it, we can tell that students the true in answering questions changes when their milieu gets hotter. As can be seen, they answered with higher true statement at 23. 5? C, and kept the percentages of cook up answers around 80%.A peak of approximate 85% was reached when the academic terms went for 2 hours (120 minutes). Although during the first 1. 5 hours (90 minutes) students responded even to a greater extent castigately at 20? C, the verity percentage wherefore decreased to about 65% in the following time. As for situations at 27? C, it seemed that students showed a relatively lower floor of true statement in the whole sessions, and the sink answers accounted for around 65% and never went beyond 70%.After this, another(prenominal) experiment was conducted with alone factors staying th e same, except a change in the tasks dealt from English comprehension to mathematics. Results are displayed in Figure 2. Its easily to abide by that at 23. 5? C students answered as well around 80% questions square uply during the 3-hour math session, and performed better 2 hours (120 minutes) later at accuracy of 85%. However the highest accuracy in the first 1. 5 hours (90 minutes) was corresponding to the environment temperature setting at 20?C, and 85% it represented. With time passing, there were more and more wrong answers and the accordingly down-sloping trim of accuracy stopped at the balance of the session, at approximate 75%, which were unsounded 10% higher than the best correct answer percentage at 27? C students could get. The corresponding ratio of unspoilt answers began at 60%, then followed an affix and mounted at 65% 2 hours (120 minutes)later. Then it tended to drop slightly, and finally expend to 63%.From what have been observed in both Figure 1 and Figur e 2, it is quite clearly that thermal environment do have an effect on students performance. Moreover, what particularly noteworthy is that 23. 5? C proves to be better linked with a better performance on accuracy at the most time. This temperature ensures 80% of responses correct during a 3 hours (120 minutes) session, and even a higher percentage when matched with an appropriate session time setting less than 3 hours (180 minutes). For those sessions lasting for less than 2 hours (120 minutes), environment temperature of 20?C can to a fault guarantee the same high percentage of accuracy, with shorter the lasting time, higher the percentage. Also another thing worthwhile noting is that 20? C clearly beats 23. 5? C when sessions are less than 1. 5 hours (90 minutes). In conclusion, higher performance may be achieved when classroom temperature ranging between 20 to 23. 5? C. Also limitations of the whole experiments exist, such as the weakness of experiment samples in representing th e ecumenic students, considering they were all NUS students.
