Millennials currently prefer web-assisted interactive media as a learning resource rather than reading books. To understand the contents of the book, students need high literacy skills. Unlike the web-assisted interactive media, the explanations are accompanied by pictures and simulations that can help students to understand the learning material. The developed web-assisted interactive learning media had been adjusted to the 2013 curriculum. This research aimed to develop a valid, effective, and practical interactive web-assisted learning media. The research development model used was the 4D model which consisted of Define, Design, Development, and Dissemination stages. The instrument used in this study was a validation sheet, a questionnaire to measure the practicality, and a creative-thinking test to measure the effectiveness. The results of validation showed that the developed learning media obtained an average score of 86.17% and had met the validity criteria with excellent quality. The questionnaire obtained a score of 88.39% which indicated that the developed learning media was effective. The developed web-assisted interactive learning media met the effectiveness criteria with the obtained average score of 80% based on four indicators, namely fluency, flexibility, authenticity, and detail. It can be concluded that the web-assisted interactive learning media is suitable to be used as a learning resource.

Assessment is an essential part of the learning process in higher education. As a result, the assessment should involve students in addition to lecturers. The purpose of this study is to examine the self and peer assessments on the answers to midterm and final-semester exams given by lecturers and their relationship with student achievement. The participants in this study were 114 fifth-semester mathematics education students who took differential equations courses. Data were gathered from student assessment scores on the middle and final test and student achievement in the lecturer's differential equations courses. The data were analyzed using descriptive statistics and an independent sample t-test to describe the self and peer assessments. Pearson correlation analysis was also used to describe the relationship between self and peer assessment and learning achievement. The study revealed no significant difference between self and peer assessments, both midterm and final semester assessments. The midterm assessment said that the average self-assessment was higher than peers. Meanwhile, the assessment average scores obtained in the semester's final exam were nearly identical between the two assessors. There is a positive and significant correlation with a high level of self and peer assessments, both in the midterm and final semester, and a positive and significant correlation with a moderate level of self and peer assessments with learning achievement. These findings can be used as a basis for lecturers to consider when involving students in assessing student achievement.

To prepare students to compete in 21st-century skills, the Ministry of Education and Culture of the Republic of Indonesia integrates character education into school subjects. However, as a medium, comics do not contain the level of character values, exploration, and critical thinking skills in problem-solving on geometry material. Therefore, the aim of this study is to produce digital media based on character values on mathematical critical thinking skills in solving problems related to learning styles for eighth-grade students. This development research employed the 4-D method (Define, Design, Develop, and Disseminate). The study indicates that the digital comic learning media is valid with a total average score of 3.60 based on the material expert’s validation and 3.50 based on the media expert’s validation. The eight-grade students' responses were positive (92%) based on the trials. The learning outcomes in terms of kinesthetic, auditory, and visual learning styles used in this study can all meet all indicators of mathematical problem-solving.

The present study investigates the self-efficacy (SE) of education students concerning their understanding of educational materials and mathematical problem-solving skills. SE, a crucial motivational construct, plays a vital role in academic achievement and cognitive development. The research employed a quantitative approach, utilizing a structured questionnaire to collect data from 155 mathematics education students and 67 biology education students. The questionnaire using a Likert-type scale comprised two main sections: one assessing SE beliefs related to understanding educational materials and the other focusing on SE beliefs associated with mathematical problem-solving. The data analysis was performed using descriptive and inferential statistical methods, including correlation analysis and independent t-tests by JASP 0.16.3.0. The findings provide valuable insights into the SE of education students in the context of different disciplines. The study reveals the overall SE levels of mathematics and biology education students in understanding educational materials and mathematical problem-solving are moderate level. There is no significant relationship between the SE of mathematics and biology education students in understanding materials and mathematical problem-solving. However, there are significant differences in SE for both understanding materials and mathematical problem-solving between the two groups. The implications of these findings for instructional practices are discussed.

This study investigates the impact of using GeoGebra as a geometric visualization tool on reducing mathematics anxiety among students in a Mathematics Education program. GeoGebra, an interactive software, enables dynamic visualization of geometric concepts, potentially fostering deeper conceptual understanding and alleviating anxiety in learning mathematics. A one-group pretest-posttest design was employed, consisting of three phases: preparation, implementation, and data analysis. Data were collected through a mathematics anxiety questionnaire administered before and after the intervention using Google Forms. The participants were 45 Mathematics Education students enrolled in an Analytical Geometry course. Data analysis involved tests of normality, homogeneity, and a paired sample t-test. The results indicate that: (1) GeoGebra effectively reduces students' anxiety in learning geometry; (2) its interactive visualizations enhance conceptual understanding and mitigate anxiety levels; (3) there is a statistically significant difference in anxiety levels before and after the use of GeoGebra; and (4) students reported a more enjoyable and less stressful learning environment, which increased their engagement with the course content. These findings suggest that integrating GeoGebra into geometry instruction can be a valuable pedagogical strategy for reducing mathematics anxiety and promoting meaningful learning experiences

This study aims to analyze trends and discuss future career expectations and interests in science education through a bibliometric approach based on Scopus data (2019-2024). Using the PRISMA method, 363 selected articles were analyzed through VOSviewer and Excel to map publication dynamics, citations, collaboration between countries, and research focus. Results showed a significant increase in publications since 2019, with a peak in 2023-2024 due to technology adoption during the transition period since the onset of the pandemic. The United States is one of the countries with the highest number of publications (3 documents). The highest-cited publication was an article by Lent and Brown (2019) in the Journal of Vocational Behavior, which received 285 citations. This article discusses the development of Social Cognitive Career Theory (SCCT) over the past 25 years and evaluates the empirical status of the theory's interest, choice, and performance models. From 2019 to 2022, the number of documents recorded was relatively stable, with slight fluctuations around 55-57. This indicates that during this period, interest in continuing education or career expectations tended to stagnate without any significant increase. However, there was a drastic spike from 2023 to 2024, where the number of documents increased sharply from around 55 to over 80.

Local content learning has yet to be fully implemented administratively in Lembata District. This condition is because Lembata Regency has a variety of cultures in each District. Several examples of the use of regional languages have a type with unique and distinctive nuances. This research aims to produce a curriculum set product equipped with a lesson plan (RPP) that accommodates learning in the context of local culture. This research is a research and development with the ASSURE model. The test subjects (users) in this study were teachers and fourth-grade students at SD Naga Wutung District, Lembata Regency. Data was collected using a curriculum expert validation questionnaire and a test questionnaire for users (teachers and students). The results of the data findings were then processed and analyzed descriptively. Based on the validation results of curriculum experts, a score of 83% was obtained with valid criteria and feasible to use. Based on user trials (teachers and students), a score of 85% was obtained with applicable standards but needed to be supplemented with other teaching media in the form of technology-based media. Implementing Lembata District's culture-based curriculum implies that teachers can implement learning and develop learning tools based on cultural curriculum offerings under the applicable curriculum.

Kelelahan merupakan salah satu faktor penyebab kecelakaan transportasi, ditandai dengan menurunnya kinerja fisik dan mental yang mengakibatkan kurangnya kewaspadaan karena rasa kantuk. Penelitian ini bertujuan untuk mengetahui faktor risiko dan faktor pendukung kelelahan pada operator alat berat. Penelitian dilakukan pada operator alat berat di 3 tambang batubara di Kalimantan (2 area di Kalimantan Timur dan 1 area di Kalimantan Selatan), melibatkan 353 operator alat berat yang bekerja dengan 3 sif. Hasilnya menunjukkan bahwa keluhan kelelahan semakin tinggi dengan meningkatnya usia, lama kerja, dan kerja pada sif 3 (malam hari). Kelelahan paling banyak dirasakan oleh operator dump truck (bagian hauling) yang dipengaruhi oleh faktor-faktor pekerjaan (postur saat bekerja, faktor variasi pekerjaan, beban kerja dan vigilance) dan faktor-faktor bukan pekerjaan (kondisi medan atau area tambang yang berisiko, penerangan yang kurang pada malam hari, dan rute yang selalu berubah). Faktor lainnya berkaitan dengan masalah sosial-psikologis, baik yang berhubungan dengan pekerjaan maupun lingkungan kerja, seperti waktu istirahat, standar gaji yang belum memadai, pengaturan jadwal cuti yang sering tidak jelas, dan masalah karier. Disimpulkan, secara umum kelelahan meningkat dengan bertambahnya usia dan lama kerja, dengan kelelahan yang lebih besar pada pekerja sif 3. Umumnya, penurunan waktu reaksi pekerja sif malam lebih besar daripada waktu reaksi pekerja sif siang. Fatigue is one of the causes of transportation accidents, characterized by reduced physical and mental performance resulting in reduced alertness due to drowsiness. The present study was to determine the risk factors and contributing factors of fatigue suffered by heavy equipment operators. The study was conducted at three coal mining sites in Kalimantan (2 areas in East Kalimantan and 1 area in South Kalimantan) involving 353 heavy equipment operators who work in shifts. It was found that fatigue complaint is higher by older age, longer work, and work at shift 3 (night time). The fatigue is mostly complained by dump truck (hauling part) operators which was influenced by work-related factors (work posture, job variety, workload, vigilance) and non-work related factors (terrain or mine risk area, lack of lighting at night, and route track which is always changed). Another factors related with socio-psychological factors, either related with job or working environment, such as adequacy of rest time, remuneration system, leave system, and insecure career. It is concluded that in general the fatigues were increased as the worker ages were older and longer duration of work, with higher fatigues were suffered at shift 3. Generally, reduced reaction time among shift 3 workers is higher than that those of daytime shift.
