Khusnul Khotimah, Ino Angga Putra — Wed, 28 Jan 2026 00:00:00 +0000

This study aims to analyze the effectiveness of an e-book based on the Numbered Team in Guided Discovery (NTGD) model in improving students’ analytical thinking skills on the topic of derivatives of algebraic functions. The research employed a quantitative approach using a pre-experimental one-group pretest–posttest design involving a single class of 25 students selected through purposive sampling. The research instrument consisted of an essay-type analytical thinking skills test measuring three indicators: the ability to identify problems, analyze relationships among concepts, and draw logical conclusions. Data were analyzed using the Shapiro–Wilk normality test and a paired-samples t-test at a significance level of 0.05. The results indicated that both pretest and posttest data were normally distributed and that there was a statistically significant difference between pretest and posttest scores, with a t-value of –13.171 and a Sig. (2-tailed) value of 0.000 < 0.05. These findings indicate that the use of the NTGD-based e-book had a significant effect on improving students’ analytical thinking skills on the topic of derivatives of algebraic functions. Therefore, the NTGD-based e-book is worthy of consideration as an alternative learning medium for developing higher-order thinking skills in mathematics learning.

Wed, 28 Jan 2026 00:00:00 +0000

One of the key elements in education is student learning motivation. Learning motivation is an important factor influencing student success in the learning process. This study aims to examine the application of the Team Games Tournament learning model in improving student learning motivation in Islamic Religious Education subjects. This study used a descriptive qualitative approach, with data collection through interviews, observations, questionnaires, and documentation. The results showed that the Team Games Tournament model was effective in increasing student learning motivation, as seen from increased student participation, enthusiasm, and enjoyment during learning. Students became more motivated because the learning process was presented in a fun, challenging way, and actively involved all group members. However, several challenges were identified, such as students' unpreparedness in facing competitive situations and diverse academic abilities within the group. Therefore, the Team Games Tournament model is effective in improving student learning motivation, especially when implemented with strategies that consider students' mental and academic readiness. It is hoped that this study can serve as a reference and basis for further research with a focus on improving the implementation of the Team Games Tournament model more optimally, such as developing tournament variations that are friendly to anxious students, and integrating Team Games Tournament with other learning models for different subjects.

Wed, 28 Jan 2026 00:00:00 +0000

This research aims to develop Google Sites-based learning media on Thermodynamics material and test its feasibility through expert validation. The research method used is research and development (R&D) based on the Borg and Gall model, but it is limited to the fifth stage. The development process includes identifying potential and problems, data collection, product design, validation by experts, and revision. The media was developed in the form of an interactive learning site that contains Thermodynamics material, learning videos, practice questions, AR, e-LKPD, and Augmented Reality (AR) content. Validation was carried out by a material expert and a media expert using a questionnaire in the form of a rating scale. The results of the data analysis show that the Google Sites-based learning media obtained a "Good" feasibility category with an average assessment percentage above 80%. This shows that the developed media is suitable for use as an alternative digital learning medium that is interactive, flexible, and supports the visual and systematic understanding of physics concepts.

Learning is a process in which students interact with educators and various learning resources in an environment that supports learning activities. This research is motivated by the challenges in learning Aqidah Akhlak at Islamic Junior High School Rahmat Said Bongkot Peterongan, where students often experience difficulties in understanding the material and low interest in learning due to the use of learning media that are less creative and monotonous. The main objective of this research is to develop an effective PowerPoint-based interactive learning media to improve student understanding. This research uses the Research and Development (R&D) method with the ADDIE model approach. The validation results show that the media is very valid with an average acceptance rate of Aqidah Akhlak teachers of 93.7% and ICT teachers of 81.8%. In addition to validation, this media was also tested for practicality and was declared practical with an assessment of 88.8% from Aqidah Akhlak teachers. The effectiveness test was conducted on 29 eighth-grade students, and the results showed that 26 students (89.6%) succeeded in achieving learning completion, which is included in the "very good" category. The student response questionnaire also showed a positive response to the use of this media. Thus, it can be concluded that this PowerPoint-based interactive learning media is highly effective and suitable for use in teaching aqidah and akhlak. This media has been proven to increase student understanding and interest in learning, thus providing an innovative solution to address existing learning challenges.

In education, AI technology has transformed the education curriculum, especially in the fields of technology, science, mathematics, and engineering. This research aims to determine the influence of using the Grammarly application on improving the writing skills of Islamic senior High School Al-Bairuny Jombang students. This research design is a quantitative experimental research design. The type of experimental research design used is a pre-experimental research design. The population of this study is extra-class A group student from class XI, Islamic senior High School Al-Bairuny Jombang, totaling 38 students. The sample for this research is students from the extra-class A1 class XI Islamic senior High School Al-Bairuny Jombang, totaling 20 students. The results show an increase in students' writing abilities. This can be proven by the average pre-test and post-test scores. The pre-test score was 78.25, and the post-test score was 80.90. Based on the findings of this research, it can be seen that using the Grammarly application as a media can have an influence on improving writing skills. Based on the research findings showing improvements in students' writing scores after using Grammarly, future researchers are advised to expand the scope of the study. Rather than focusing on just one group, it would be better to use a more robust experimental design, such as comparing a group of students who used Grammarly with another group who did not.

Khalawatul Iman, Nurul Afidah, Ulfa Wulan Agustina, Yuyun Bahtiar — Wed, 28 Jan 2026 00:00:00 +0000

Writing is an activity where someone can express their ideas in writing. AI in education refers to the use of technology that can be utilized in education. One example is in the learning process, which can be interactive and innovative. This research is urgent given the importance of English language skills as a tool for international communication, especially in developing countries like Indonesia. The purpose of this study was to determine students' perspectives on the use of DeepL Translate in writing skills. In the context of language learning, artificial intelligence-based translation tools such as DeepL Translate are increasingly popular among students. This study used a mixed method, combining quantitative and qualitative approaches. Quantitative data were collected through questionnaires distributed to students, while qualitative data were obtained through in-depth interviews with several students who used DeepL Translate in the process of writing descriptive texts. The results showed that most students had a positive response to the use of DeepL Translate. They felt this tool helped them understand new vocabulary, improve sentence structure, and increase the accuracy of their writing. However, some students also expressed concerns about the dependence on this translation tool and its potential negative impact on their independent writing skills. These findings provide important insights for teachers in understanding how technology can be utilized to support writing skills learning, as well as the challenges students face in using it.
