Data Commentary Practice
GRP 5 KONG Chao, MAO Mao, ZHOU Tingting Figure 1 indicates the corresponding fortunes of students straighten out answers to comprehension tasks at different thermal environment. According to it, we can see that students true statement in answering questions limitings when their environment gets hotter. As can be seen, they answered with higher trueness at 23. 5? C, and kept the percentages of rectify answers more or slight 80%.A peak of approximate 85% was reached when the sessions went for 2 hours (120 minutes). Although during the first 1. 5 hours (90 minutes) students responded even more correctly at 20? C, the accuracy percentage then decreased to about 65% in the following clock time. As for situations at 27? C, it seemed that students showed a relatively lower degree of accuracy in the whole sessions, and the correct answers accounted for rough 65% and never went beyond 70%.After this, other experiment was conducted with all factors staying the same, except a change in the tasks dealt from English comprehension to mathematics. Results are displayed in Figure 2. Its easily to notice that at 23. 5? C students answered also around 80% questions correctly during the 3-hour math session, and performed conk out 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 trend of accuracy stopped at the end of the session, at approximate 75%, which were save 10% higher than the best correct answer percentage at 27? C students could get. The corresponding ratio of right answers began at 60%, then followed an increase and mounted at 65% 2 hours (120 minutes)later. wherefore it tended to drop slightly, and finally fell to 63%.From what have been observed in both Figure 1 and Figure 2, it is quite clearly that thermal en vironment do have an effect on students surgical procedure. Moreover, what particularly famous 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 take into account 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 also ascertain the same high percentage of accuracy, with shorter the lasting time, higher the percentage. as well as 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 the universal students, con sidering they were all NUS students.
