<p class="Abstract">Drawing – based modeling as learning approach, it allows students to create models based on drawing which help them to run a simulation. Students can use drawing–based modeling to learn a pair of interacting population known as predato–prey system while they usually conducted practicum using diagram of organisms. This study was to explore students’ argumentation and students’ understanding on the concept of the ecosystem. The study was conducted quasi – experimental using the matching – only post-test – only control group design. The participants consist of 60 grade 10 senior high school students in Subang, West Java. They are placed into two groups, 30 students in the experimental group and 30 students in the control group. Data was collected through argumentation test and selected response test for assessing students’ understanding. Students’ argumentation were analyzed using Toulmin’s argumentation pattern and statistical analysis. The result showed there is no significant difference between the experimental group and the control group for students’ argumentation. Most of the students are predominantly at level 2. But the coherency of arguments of the experimental group is more coherent than the control group. It means that the students in experimental group can make logical claim and supported by the correct and relevant grounds (data, warrant, and backing). The result of students’ understanding showed there is a significant mean score between the experimental group and the control group whether 72.33 for the experimental group and 62.13 for the control group</p>

This study aims to improve students' science process skills by applying a guided inquiry learning model to the concept of work and energy learning physics. The research design used was a quasi-experimental control group design. The population in this study was all class X MIA SMA Negeri 5 Banda Aceh, which consisted of five parallel classes who took the science program in the even semester of 2020/2021 with a total of 139 students. Two classes as the research sample were selected by purposive sampling by taking into account the average value of physics for each class. Meanwhile, the determination of the experimental and control classes in this study was carried out randomly. Data on science process skills in both classes was obtained through observation sheets filled out by two observer teachers. The results of data analysis show that, in general, there is a significant difference between the improvement of science process skills in the experimental class and the control class for the indicators of observing, predicting, measuring, communicating, and concluding. However, for classifying indicators, the results were not significantly different. The improvement of science process skills in the experimental class in general for all of these indicators certainly cannot be separated from each step of the guided inquiry learning model they carry out. The positive results of the implementation of physical learning through the inquiry model on students' science process skills can be used as a reference and support for teacher implementation in carrying out the teaching and learning process of physics, especially on the concept of business and energy

Background: High mobile-phone dependency may cause cognitive, emotional, and academic impairments among students; hence, proper therapies should be performed to prevent the risk. Objectives: The present study aimed to investigate the effectiveness of the nomophobia therapy package on self-esteem and nomophobia symptoms in high school students. Methods: The research method was quasi-experimental with a pre-test, post-test, and follow-up design and a control group. The statistical population included all the students showing nomophobia symptoms who were in high schools in Isfahan in the academic year of 2018 - 2019. Using purposive sampling, we selected 30 students willing to participate in the project and randomly divided them into experimental (n = 15) and control (n = 15) groups. The research instrument included Nomophobia Questionnaire and Self-Esteem Questionnaire. The experimental group underwent eight sessions (75-minute sessions per week) of nomophobia therapy. The follow-up was performed after two months. Data were analyzed by descriptive and inferential statistics, such as mean, standard deviation, and repeated measures ANOVA. SPSS version 23.0 was further used to analyze the data. Results: The mean ± SD of the post-test scores of self-esteem and nomophobia symptoms were (19.26 ± 3.34) and (50.60 ± 5.07) in the experimental group and (13.46 ± 2.47) and (71.63 ± 8.47) in the control groups. The difference between the scores of the experimental and control groups in the pre-test was not significant (all P-values were > 0.05). Also, the post-test scores did not have a significant difference from the follow-up scores (all P-values were > 0.05). Nomophobia therapy effectively increased self-esteem in students with nomophobia symptoms in the experimental group (P = 0.0001). The training intervention sessions decreased the nomophobia symptoms of high school students in the experimental groups compared to the control group (P = 0.0001). Conclusions: According to research findings, nomophobia therapy was an efficient therapy for improving self-esteem and reducing nomophobia symptoms in students who suffer from the syndrome.
