CHAPTER II LITERATURE REVIEW
B. Previous Study
2. Highly depends on the teacher's communication style, because style can affect student understanding, so the teacher's communication style must be clear.
3. If the material presented is complex, detailed or abstract, the direct instruction learning method may not give students sufficient opportunities to process and understand the information presented.
4. If used too often, the direct instruction learning method will make students believe that the teacher will tell students everything they need to know.
collaborative learning with quantum teaching increase the students' ability to read at the nine grade students of SMP Negeri 4 Suppa.
Second, research by Muhammad Rizwan Hasim, in his thesis entitled Improving Students' Vocabulary by Using A Quantum Teaching Method (2019) the population of this study is VIII grade SMPN 01 Suwawa Gorontalo in academic year 2018/2019, and Sample of this research is 20 students. The researcher used experiment method and the design was pre-experimental with one group pre-test post-test. The result of this study showed that the total score of post-test was 190 and the total score of pre-test was 101. The hypothesis was tested by using a t-test formula. In this case, the researcher found that the tcount is bigger than ttable (4, 81894
> 2, 086) with the level of significance a = 0, 05. Based on the result of the data analysis, the hypothesis of this study is accepted. It can be concluded that a quantum teaching method can help students' improve their English vocabulary capacity mastery.
Third, the research title is 'The Effectiveness of Quantum Learning Method on Students’ Vocabulary Muslim’ Daily Activities at the Eight Grade of MTs Al Hikmah Balekencono Batanghari East Lampung 2018/2019” (2019) by Novi Junitasari, The population of this research is the eighth-grade students. A sample of 26 students determining through the clustering sampling technique. The data collect uses test and documentation. The result of the “tobservation” is 5 bigger than “ttable” 5%(0,404) and 1%(0,515). Her result is said that quantum learning method effective on students’ vocabulary Muslims daily activities at the eight grade of MTs Al Hikmah Balekencono.
Fourth, Eko Susanto (2017) in his thesis entitled "A Comparative Study Between Quantum and Conventional Learning Method on English Articles Mastery of Eight Graders at SMP Swasta AL Washliyah 1 Medan". This research is an experimental research. The population in this study were all students of class VIII SMP Swasta Al Washliyah 1 Medan which consisted of two classes of 60 students.
The sample of this study was 30 students for each experimental class and control class. The instrument for collecting data in the research is t-test. The data were analyzed in this study using the t-test formula. The results of this study indicate that the average is 70,333 for the experimental class and 53,367 for the control class.
The variant of the quantum learning method is 101,687 and the variant of the conventional learning method is 91,203. The results of the analysis show that tcount
= 6.70 is higher than ttable = 1.99 with a significance level of 0.05. So that it can be interpreted that the mastery of students' English material taught by the quantum learning method is better than that taught by conventional learning methods.
Based on previous studies, there are some differences between this study and the studies above. In the previous first study, the researcher used the quantum teaching method in teaching reading comprehension. In the second study, researchers used the quantum teaching method to increase students' vocabulary.
Third, the researcher uses the quantum learning method in the daily activities of students' Muslim vocabulary. For the last study, the researcher sought a comparison between quantum and conventional learning methods on mastery of English articles.
In this study, there are some similarities between the research mentioned above and the research conducted by the author. There is no denying that previous research has focused on the use of quantum in conducting research. However, in this study, the researcher used quantum teaching to see if the method could be effective in teaching writing descriptive text.
