A Comparative Study of Students’ Achievement on Conditional Sentences between Those Who Are Taught through WhatsApp and Google Meet

Abstract

This research aims at investigating the difference of students’ achievement on conditional sentences between those who are taught through WhatsApp and Google Meet, and also finding out which one is more effective to improve students’ achievement. The population of this research was all IPA students of SMA Negeri 1 Kendari at XI grade consisted of ten classes, while the samples were class XI IPA Unggul B and XI IPA 1 consisted of 35 students of each class. This research was conducted in quasi-experimental design. The researcher used pre-test and post-test to collect the data, while the treatment was done by using WhatsApp and Google Meet in two different classes. The result showed the students’ mean score of WhatsApp class is 37.85 on the pre-test and 73.42 on the post-test, while the students’ mean score of Google Meet class is 53.71 on pre-test and 75.14 on post-test. As result, there is an improvement of the students’ mean score of each class in post-test. However, after calculating the N-Gain score for both of the classes, the mean score of the WhatsApp class is higher than the Google Meet class. To prove the hypothesis, the researcher takes the conclusion by comparing the Sig.2 tailed and Alpha value using T-Test. It shows that the Sig.2 tailed is less than Alpha value (0.000 < 0.05). Therefore, it can be concluded that there is a significant difference of students’ achievement on conditional sentences between those who are taught through WhatsApp and Google Meet, also WhatsApp is proven to be more effective to improve students’ conditional sentence achievement.
