EFFECT OF QUIZIZZ APPLICATION ON THE STUDENTS’ READING COMPREHENSION

This study aims to ascertain whether using the Quizizz application affects students' reading comprehension abilities in seventh-grade junior high school. The researchers used a pre-experiment design with a single group design to conduct this quantitative study. Seventh graders at one of Surabaya's public junior high schools served as the study's sample. Pre-test and post-test were utilized in this study to gather data. This study examined a paired sample t-test to collect the information. The t-test indicates that the student's scores after receiving the treatment are higher than the students' scores before, as evidenced by the average score's increase from 64.41 to 81.12. The Alternative hypothesis is accepted as there is a substantial impact of utilizing Quizizz on students' reading comprehension abilities, according to the findings of the paired sample t-test, which revealed that the Sig (2-tailed) score is 0.000 <0.05. It has implied that Quizizz could improve students' reading comprehension since the teacher provides valuable knowledge for students. They are motivated to read English text using Quizizz. It is recommended for future research to explore the application of Quizizz for other skills.

THE EFFECT OF THE ENVIRONMENTAL EXPLORATION APPROACH ON CURIOSITY, CRITICAL THINKING SKILLS, AND SCIENCE LEARNING OUTCOMES

The natural environment around students can become a learning object that provides students with real experiences. This research aims to determine the effect of the Exploring the Natural Environment (JAS) approach on (1) students' curiosity, (2) students' critical thinking skills, and (3) student learning outcomes. This research uses a quasi-experimental design. The population consists of seventh-grade junior high school students. Data collection techniques are carried out using tests and observations. Prerequisite tests are carried out using validation tests, homogeneity tests, and normality tests. The hypothesis analysis technique is carried out using the independent simple t-test. The research results obtained are, One, there is an influence of the JAS approach on students' curiosity with a sig-2tailed result of 0.011 ≤ 0.05, Two, there is no influence of the JAS approach on students' critical thinking skills with a sig-2tailed result of 0.080. This is because students still do not fulfill the six categories of critical thinking according to Facione, Three, there is an influence of the JAS approach on student learning outcomes with a sig-2tailed result value of 0.003 ≤ 0.05. This research concluded that the natural exploration approach (JAS) had an influence on students' learning outcomes and curiosity, but had no effect on students' critical thinking skills. The obstacle in this research is that the time used is still very limited, so better time management is needed.

Mental Representation Level of Junior High School Students in Cell Biology Concept Based on Gender

This study aims to determine the level of mental representation of seventh-grade junior high school students in cell concepts. The research method used was the explanatory sequential mix method with 60 research subjects. The instruments used in this research were the Mental Diagnostic Test (MDT), which consists of a reasoned true and false test, a symbolic test, and an imaging test. Based on the results obtained from the answers to the MDT instrument, it can be seen that the levels of mental representations are categorized into Initial mental representation, Intermediate mental representation 1, Intermediate mental representation 2, Consensus representation, and Target representation. The results show that on the MDT instrument, the average student is included in the intuition and experience mental model. The level of the mental representations of male students is higher than that of female students. The mental representation of the initial level, intermediate 1, and the target in male and female students have the same level; the difference occurs at the intermediate level 2 and consensus. Male students (30%) have higher intermediate level 2 than female students (20%). Furthermore, there are 10% male students and no female students at the consensus level. This research concludes that the information level profile of mental representation is identified as having the type of intuition and experience.

Reading passages and conversation text in EFL textbook for junior high school: Analysis on the process of transitivity system

This research aims to identify the process types of the transitivity system from the reading passages and conversational texts of the EFL textbook entitled Modul Pengayaan for seventh-grade junior high school students, which is composed based on the implementation of Kurikulum 2013. The present study employed a descriptive qualitative research design. The data of this study are obtained from reading texts and conversational texts (text dialogues). The collected data of the transitivity process presented in sentences and clauses were analyzed using Halliday's transitivity system. The results show that all the process types of transitivity system with 35 processes were found in the reading passages and conversational texts of the textbook, namely: material process with 5 data (14.28%), mental process with 12 data (34.28%), verbal process with 3 data (8.57%), relational process with 13 data (37.14%), behavioral process with 1 data (2.85%), and existential process also with 1 data (2.85%). All the types of transitivity processes have been presented adequately based on Halliday's theory, although the two types of transitivity process (behavioral and existential process) almost have come from ignorance. Therefore, this study suggests that the textbook designer and material developer produce diverse clauses and sentences by using the six process types of transitivity in English written texts, especially in the reading passages and conversational texts.
