This study aims to determine the level of problematic smartphone use (PSU) and revenge sleep procrastination (RBP) among MTs/SMP students in District X, while also examining the relationship between the two variables. The problem of excessive smartphone use among adolescents is increasingly important to study because it can impact sleep quality, learning concentration, and mental health. This research approach uses a quantitative correlational method with data collection through a bold questionnaire (Google Form). The research sample consisted of 103 MTs/SMP students in District X who were selected using an incidental sampling technique. The RBP variable measurement scale was developed by the researcher with reference to aspects proposed by Kroese et al. (2014). Meanwhile, the PSU Scale was developed based on dimensions formulated by Foerster et al. (2015), including withdrawal, desire, loss of control, dependence on peers, and negative life consequences. The results of the correlation analysis showed that PSU had a very strong positive relationship with RBP (r = 0.833) and was statistically significant (p < 0.000). This means that the higher a person's tendency to experience problematic smartphone use, the greater the likelihood of revenge bedtime delay. Among the dimensions of PSU, withdrawal showed the highest correlation with RBP (r = 0.831). This was followed by negative life consequences (r = 0.778), craving (r = 0.577), loss of control (r = 0.489), and dependence on peers (r = 0.333). Overall, this study concludes that PSU plays a significant role in increasing RBP trends among students. These findings highlight the urgent need for awareness and intervention programs to reduce excessive smartphone use among adolescents. Therefore, the results of this study are expected to serve as a reference for schools and parents in designing strategies to prevent the negative impacts of smartphone use on adolescents.

This community service activity was carried out with the aim of improving the memory of students at the Baiturrahman Islamic Boarding School (TPQ) through the implementation of group guidance based on an interactive question and answer method. The background of this program is based on the problem of low retention of religious material that has been learned by students, so the learning approach is needed that does not only emphasize memorization, but also activates the process of critical and in-depth thinking. In its implementation, the activity is designed to involve students directly in group discussions guided by a facilitator. The questions posed are structured in such a way as to stimulate repetition of information, encourage logical reasoning, and help students connect the learning material with real experiences in everyday life. Through this process, students are not only asked to answer questions but are also trained to develop broader answers, thereby strengthening understanding and improving communication skills. This program also prioritizes a fun, collaborative, and participatory learning atmosphere so that students feel more motivated to actively participate. Evaluation results show a significant increase in students' ability to remember, understand, and re-present learning material more quickly, accurately, and coherently. Furthermore, this activity also has a positive impact on increasing students' self-confidence in the learning process and strengthening collaborative skills among group members. Thus, group guidance using the question-and-answer method can be considered an effective learning strategy for strengthening students' memory and increasing their learning motivation.

Using Newman's Error Analysis (NEA) as a framework, this study will examine the many ways in which MAN 3 Medan students blunder while answering problems involving logarithms and exponentials. A total of thirty-one MIPA class X students served as subjects for this qualitative descriptive study. Essay tests, interviews with math instructors, and records of student work all contributed to the data set. Data analysis involves reducing, presenting, and making conclusions while triangulating sources to ensure the data is legitimate. According to the research, the two most common points of mistake are when people are trying to grasp the issue and when they are trying to convert it. This is because pupils have a hard time grasping the characteristics and fundamental ideas of logarithms and have a habit of rote memorization rather than critical thinking. Other factors that also affect include the lack of utilization of learning media and low student learning motivation. After being given discussion-based learning and interactive media, the post-test results showed an increase in comprehension and a decrease in conceptual errors. This research recommends that teachers should emphasize student-centered learning by strengthening basic concepts and implementing contextual problem-solving strategies.

This research aims to develop an electronic student worksheet (E-LKPD) based on Liveworksheet, integrated with Quizwhizzer, for teaching economic activities in elementary school. The background of this study stems from the limited variation in learning activities and the underutilization of digital technology in the learning process at schools. To address these problems, the study seeks to produce innovative, interactive, and easily accessible learning media that can support student engagement and improve learning outcomes. The development process follows the ADDIE model, consisting of five stages: Analyze, Design, Development, Implementation, and Evaluation. In the analysis stage, the needs of students and teachers were identified. The design and development stages involved creating E-LKPD content integrated with Liveworksheet and interactive quizzes using Quizwhizzer. The implementation was carried out through classroom trials, followed by evaluation to assess the effectiveness and feasibility of the product.

This learning media is expected to increase students' interest, motivation, and active participation, while also optimizing the role of technology in supporting a more engaging and meaningful learning experience in the classroom.

This study aims to examine the application of the Project Based Learning (PjBL) model assisted by animated videos in improving problem-solving skills in Natural and Social Sciences (IPAS) subjects. The study used a quasi-experimental approach with a one-group pretest and posttest design. The subjects were 30 fifth-grade elementary school students selected as samples. The research instruments included a problem-solving ability test and an observation sheet for the implementation of learning. The results showed a significant increase in students' problem-solving skills after being treated through the PjBL model assisted by animated videos. The average posttest score was higher than the pretest, so it can be concluded that this learning strategy is effective in improving student learning outcomes. The use of animated videos helped students to visualize abstract concepts and engage more actively in the learning process. In addition, the results of observations of the implementation of learning showed that students became more active, enthusiastic, and able to work together in groups to complete the project. Student activity increased gradually, starting from the project planning stage, information collection, to the presentation of results. The teacher acted as a facilitator who provided direction and guidance, while students were directly involved in each process. This indicates that the integration of technology-based media supports collaborative and student-centered learning. Therefore, the implementation of the Project-Based Learning model with animated videos is not only effective in improving problem-solving skills but also fosters overall student engagement in science learning. Therefore, this learning model can be recommended as an innovative strategy to enhance problem-solving skills in primary education.

This study aims to describe the mathematical literacy skills of vocational high school students in solving statistics problems with the help of Microsoft Excel based on digital literacy levels, which are grouped into high, medium, and low. The background of this study is based on the importance of mathematical literacy in dealing with everyday problems and the demands of the world of work, as well as the increasing need for digital literacy mastery in the information technology era. Both are essential competencies that support each other, especially in technology-based mathematics learning. The research approach used is descriptive qualitative with a purposive sampling technique, where the selection of subjects is based on the results of the digital literacy questionnaire, equivalence of mathematics scores, and adequate communication skills to support the interview process. The research instruments include a digital literacy questionnaire, a mathematical literacy test in the form of descriptive questions completed using Microsoft Excel, and interview guidelines that have been validated by experts. The data collection procedure was carried out through tests and in-depth interviews, while data analysis included the stages of data reduction, data presentation, and drawing conclusions. The results of the study indicate differences in students' mathematical literacy skills based on their digital literacy levels. Students with high digital literacy are able to master mathematical literacy indicators well, including communication, mathematization, problem-solving strategies, and reasoning and argumentation. They can optimally utilize Microsoft Excel features to present data, perform calculations, and draw logical conclusions. Students with moderate digital literacy demonstrate fairly good mastery, but still experience difficulties in aspects of problem-solving strategies and in-depth reasoning. Based on these findings, it can be concluded that digital literacy plays a crucial role in supporting students' mathematical literacy abilities.  

This study aims to analyze the influence of the Problem Based Learning (PBL) model in science education on students’ environmental literacy and science communication skills at SMK Negeri 3 Pekanbaru, focusing on the topic of disaster mitigation. The research employed a causal comparative approach with a post-test only design, comparing two student groups: an experimental class using the PBL model and a control class using conventional teaching. The results revealed a significant difference in environmental literacy, with the experimental class achieving a higher average score (81.86) compared to the control class (62.05). This indicates that the PBL model is effective in enhancing students' understanding, awareness, and environmentally responsible behavior. The PBL approach encourages active student engagement and the application of knowledge to real-world scenarios, which is particularly beneficial in the context of environmental issues and disaster mitigation. By working through problems related to environmental challenges, students are likely to gain a deeper understanding of the topic, which fosters a sense of responsibility towards environmental sustainability. In terms of science communication, although the experimental class showed a higher average score (75.78) than the control class (72.92), the difference was not statistically significant. This may be due to a lack of intensive training in scientific discussions and presentations. While PBL encourages collaborative problem-solving and idea-sharing, students may still require more structured practice in presenting and communicating their findings clearly and persuasively. The integration of more structured activities focusing on science communication skills could further enhance the effectiveness of the PBL model. Overall, the PBL model demonstrates positive potential in improving both environmental literacy and science communication. However, to achieve its full impact, its implementation must be consistent, with a focus on providing students with additional opportunities to develop their communication skills.

This research focuses on the role of Islamic Religious Education (PAI) teachers in actualizing the values of Ahlussunnah Wal Jamaah (Aswaja) Annahdliyah as one of the Islamic guidelines that develop and are firmly rooted in Indonesia. Aswaja values have distinctive characteristics that emphasize moderation, tolerance, and maintaining religious traditions that have been acculturated with local culture without abandoning the principles of Islamic law. In the context of education, Aswaja is an important foundation in shaping the character of students who are religious, nationalist, and able to appreciate diversity in a multicultural society. The purpose of this study is to find out: (1) how to implement the role of PAI teachers in integrating Aswaja values in the learning process at MA NU Assalafie Babakan Ciwaringin Cirebon, (2) problems that arise in the actualization process, such as limited student understanding, differences in family backgrounds, to the challenges of globalization currents that can affect religious understanding, and (3) efforts made by teachers to overcome them, for example, through a personal approach, strengthening Aswaja-based teaching materials, and collaboration with schools and parents. This study uses a qualitative method with a field study approach. Data was obtained through observation, in-depth interviews with madrasah heads, deputy heads of student affairs, and five PAI teachers, and documentation of learning activities. Data analysis was carried out through the stages of reduction, presentation, and conclusion drawn, then tested for validity with the source triangulation technique. The results of the study show that the role of PAI teachers is very crucial in maintaining the value of Aswaja so that it remains relevant and internalized in students.

This research was conducted with the main purpose of examining and analyzing the specific needs of elementary school teachers in designing and implementing a Problem-Based Learning (PBL) model that is grounded in the Technological Pedagogical Content Knowledge (TPACK) framework, with the ultimate goal of enhancing students’ critical thinking skills as a crucial competency in the 21st century. The study is rooted in the understanding that critical thinking is not only a fundamental learning outcome but also a key skill for students to thrive in modern society, while at the same time recognizing the current limitations in technology integration within elementary-level PBL practices. A quantitative descriptive method was employed, involving a purposive sample of 100 elementary school teachers who provided data through structured questionnaires and interviews. The analysis focused on five core indicators, namely teachers’ initial knowledge of TPACK-based PBL, the availability of facilities to support its implementation, teachers’ participation in relevant professional training, the degree of TPACK integration in classroom learning, and the actual application of PBL in teaching practice. Findings revealed that only 36% of teachers possessed sufficient awareness of TPACK-based PBL, 40% reported having adequate facilities in their schools, 40% had previously joined related training, 36% had integrated TPACK into their instruction, and 50% had applied PBL in their classrooms. These results clearly demonstrate a significant gap between existing practices and the ideal conditions needed for maximizing the potential of TPACK-based PBL. Consequently, the study emphasizes the urgency of developing and strengthening this model by improving teacher knowledge, ensuring continuous professional development opportunities, and promoting the effective use of technology to foster innovative, contextual, and student-centered learning that can systematically nurture critical thinking abilities in elementary school students.

The low reading interest and literacy skills of elementary school children in Indonesia remain a problem that requires creative and sustainable solutions. Factors such as limited access to quality books, a lack of reading habits at home, and uninteresting learning approaches are often the causes of a weak literacy culture among students. To address this problem, the Student Community Service Program (KKN) of Sebelas Maret University students in Singodutan Village implemented an activity aimed at fostering a culture of literacy in children through a Reading Book Content-Based Project at SDN 3 Krisak. The concept of this activity integrates reading activities with the creation of creative projects that are appropriate to the content of the reading, so that students not only understand the text but are also able to process the information into real products. This study used a qualitative approach with a phenomenological research type to understand students' experiences during the activity. Data were collected through observation, documentation, and literature review, which were then analyzed descriptively. Activities included selecting reading books appropriate to students' ability levels, shared reading, discussions about the reading content, and the creation of creative projects such as posters, picture stories, or artwork inspired by the reading material. The results of the activity showed an increase in student participation in reading activities, an increase in interest in books, and an improvement in their ability to process information into creative works. Furthermore, students demonstrated greater self-confidence when presenting their work to their classmates.

This study aims to describe students' critical thinking skills in solving social arithmetic problems based on the Polya stages and FRISCO indicators. The research subjects consisted of three students in grade VIII R-5 MTs Nurul Jadid who were purposively selected to represent the high, medium, and low ability categories out of a total of 21 students. The research method used was a descriptive qualitative approach with instruments in the form of two social arithmetic description questions and semi-structured interview guidelines. Data analysis was carried out by referring to the four stages of problem solving according to Polya (understanding the problem, planning the solution, executing the plan, and re-examination) as well as the six FRISCO critical thinking indicators (Focus, Reason, Inference, Situation, Clarity, Overview). The results of the study showed that students with high abilities were able to solve problems systematically through all stages of Polya and met almost all FRISCO indicators, especially in the aspects of Focus, Reason, and Clarity. Students with moderate ability show sufficient understanding but are inconsistent in planning and implementing solutions, and experience difficulties in the Reason, Situation, and Overview indicators. Students with low abilities experience obstacles from the early stages of understanding problems and do not show significant indicators of critical thinking. These findings indicate that the Polya stage and the FRISCO indicator can be used in a complementary manner to identify and analyze students' critical thinking skills in solving contextual math problems. The implication of this study is the need for a learning strategy that emphasizes strengthening the stages of problem solving and developing explicit critical thinking indicators in the mathematics learning process. This research also opens up opportunities for the development of more structured diagnostic instruments in measuring students' individual critical thinking skills.

This study is motivated by the difficulty students face in understanding the concept of food chains, which is attributed to the conventional teaching methods still in use. Therefore, the researcher believes that the application of a new teaching model is expected to enhance student engagement in the teaching and learning process, ultimately improving learning outcomes. Natural Science is often considered difficult because of its many theories and the lack of variation in teaching methods, leading to poor student performance. Given these issues, an innovative teaching model is necessary. The aim of this study is to examine the impact of the Problem-Based Learning (PBL) model on students' knowledge in the Natural Science subject. The research method used is an experimental method with a quasi-experimental design. The study population consists of 50 fifth-grade students, with 25 students in the experimental group and 25 students in the control group. The hypothesis tested is that there is an effect of the Problem-Based Learning model on Natural Science learning outcomes. The results of the study show that the Problem-Based Learning model has a significant effect on students' knowledge. This is evidenced by the t-test results, which show a t-value of 12.400, greater than the t-table value of 2.01. Therefore, it can be concluded that the Problem-Based Learning model positively affects the understanding of food chain concepts in fifth-grade students. The findings of this study are expected to be beneficial for teachers in improving the quality of their teaching, for students to better understand the material through more engaging methods, and for the school environment in developing innovative and effective teaching practices.

Problem-Based Learning (PBL) is a student-centered teaching approach, where the learning process begins with a real-life problem relevant to everyday life. PBL encourages students to actively seek information, analyze data, and formulate solutions through group work and discussion. This approach not only develops critical thinking, problem-solving, and communication skills but also increases students' independence and responsibility for their own learning process. This article aims to examine how PBL is implemented in two main curricula in Indonesia: the 2013 Curriculum (K13) and the Independent Curriculum. In the 2013 Curriculum, PBL is integrated through a scientific approach and project-based activities, where students are invited to explore concepts and theories through investigative activities. Meanwhile, the Independent Curriculum provides more space for teachers and students to design contextual and personalized learning activities, making the implementation of PBL more flexible and adaptive to local needs and student characteristics. The literature review results indicate that both curricula effectively utilize PBL principles to enhance students' cognitive and metacognitive skills. The Independent Curriculum, in particular, places greater emphasis on independent learning, self-reflection, and the development of student interests through differentiated learning. Thus, the application of PBL within the context of the Independent Curriculum has proven to be more adaptive to the dynamics of 21st-century learning. In conclusion, the use of Problem-Based Learning in both curricula has significant potential to enhance students' learning abilities, as long as the approach is tailored to school conditions, student characteristics, and is supported by competent teachers and training in implementing this method effectively.

This type of research is research and development using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research was conducted at SMA Negeri 1 Malinau with the research subject of class X-3 students totaling 35 students. Data collection was carried out using interview techniques, observation, e-LKPD validation sheets, pretest-posttest, and questionnaires. To determine the validity, the e-LKPD assessment sheet of material and media experts was used, practicality used student and teacher response questionnaires, and effectiveness used mathematics problem solving ability test questions and student self-confidence questionnaires. Data analysis consisted of qualitative data analysis and quantitative data analysis. Qualitative data analysis was conducted by analyzing the results of interviews, observations, and comments or suggestions given to make improvements to the e-LKPD products developed. Quantitative data analysis was conducted by converting quantitative data into qualitative data in the form of certain categories, normality test using shapiro-wilk, t-test with paired samples test, and N-Gain score. The results showed: (1) PBL-based e-LKPDs oriented towards mathematical problem solving skills and self-confidence of high school students on the material of quadratic equations and functions have been produced, (2) PBL-based e-LKPDs developed meet product feasibility, namely valid with excellent categories based on material and media experts; practical with very practical categories based on teacher responses and practical based on student responses; effective on math problem solving skills with classical completeness of 77%, the t-test results obtained a significance value of 0.000 <0.05 which means that there is a difference in the average ability to solve mathematical problems before and after learning using e-LKPD, the N-Gain result is 0.65 with moderate criteria, and effective on student self-confidence with an increase in the average score of each indicator before and after learning,  the N-Gain result is 0.49 with moderate criteria, and the t-test results with a significance value of 0.000 < 0.05.

The topics of morphology, anatomy, and physiology are integral to biology learning, yet they often present challenges for students due to their abstract and complex nature. Difficulties in understanding body structures and invisible biological processes lead to low student interest and engagement. This study aims to identify innovative learning approaches through an analysis of national scientific literature over the past decade. The results show that the integration of digital technology and student-centered learning methods can improve conceptual understanding and learning motivation. The most prominent innovations include the use of VR and AR-based media to clarify visualizations, the use of interactive videos and simulations to explain biological functions, and the application of contextual learning models such as Problem-Based Learning (PBL) and Project-Based Learning (PjBL). These approaches have proven effective in creating a more immersive learning experience that is relevant to students' needs.

This research is based on the problem faced by students who feel bored due to their lack of active role during the learning process. It is necessary to rejuvenate learning facilities that are able to attract students' interest in reading and the lack of interest in reading students in the process of learning Indonesian which has an impact on the learning process carried out. This study aims to describe the application of the Scramble method in improving students' interest in reading in the process of learning Indonesian in Class II MI Muhajirin Jambi City. The method used in this study is Classroom Action Research (CAR), with the type of data including primary and secondary data, while the subjects studied include teachers and students in class II. The method of collecting information is carried out by tests, observations, conversations, and archiving. The data analysis method uses descriptive analysis and percentages to assess success in the action. The study revealed that the interest in reading of Class II MI Muhajirin Jambi City students after participating in Indonesian language learning with the Scramble method experienced a significant increase, seen from the condition of students' interest in reading in cycle I in each indicator carried out by between 13 to 15 students, so that it is at a percentage of between 50 to 60%. In cycle II, there was a very good increase in students' reading interest, where an average of 19 to 23 students actively carried out 5 indicators of reading interest, so that the percentage of success of the Scramble method in increasing reading interest ranged from 70% to 90% with good and very good predicates. The data shows that the application of the Scramble method can increase students' interest in learning Indonesian in Class II of MI Muhajirin, Jambi City.
