Abstract

The level of science literacy in Indonesia is at a low level based on the results of the PISA test in 2018. Science literacy is an ability that must be mastered in the 21st century. Science literacy can be developed through ethnoscience. Ethnoscience is the transformation of the science of society into scientific science. This research is a literature review research with 10 SINTA-indexed journals and 2 Scopus-indexed journals. This study discusses the implementation of ethnoscience in science learning. Science learning that implements ethnoscience can be through learning media both electronic and print, learning models, direct and indirect learning resources, learning tools, and a combination of learning models and media. Learning by narrating ethnoscience can make the learning process more active, more meaningful, students can think analytically, are contextual, and can increase science literacy.

Abstract

Banyu Biru hot springs is one of the tourist attractions in Gondangwetan Village, Jatikalen District, Nganjuk Regency, which has geothermal manifestations in the form of hot springs, which indicate the existence of a geothermal reservoir below the surface. This study aims to analyze the physics concepts found in Banyu Biru hot spring tourism, as well as the physics that shapes it. This study uses qualitative research in the form of a literature review. The research was conducted by collecting library sources, classifying data, managing data, citing references, abstracting data, interpreting data, and drawing conclusions. Based on the results and discussion, it can be concluded that the Banyu Biru hot springs are a local culture in the Nganjuk Regency area. The formation of the Banyu Biru hot springs was influenced by the location of Nganjuk Regency which is between Mount Wilis and Mount Pandan. Based on the location of Nganjuk Regency, it is possible that it has something to do with the volcanic activity of the volcano. The geothermal phenomenon at the Banyu Biru hot springs was discovered after drilling a well to irrigate the rice fields. The hot water has a temperature of approximately 37°C with a depth of 250-300 meters. Apart from that, the Banyu Biru hot springs in Nganjuk Regency can be studied physically, namely there are concepts regarding geothermal energy, geothermal energy, geothermal systems, conduction and convection. This study can raise public awareness of local cultural identity through the integration of local wisdom into physics education.

Abstract

Physics education in some schools still uses conventional methods, which focus on memorizing physics concepts without involving other aspects. Such methods lead students to view physics as uninteresting, difficult, and abstract. Therefore, in order for students to understand better and be more enthusiastic about each physics lesson, there is a need for innovative teaching. One way is to integrate a deep learning pedagogy approach into the curriculum. This approach has three main elements: meaningful, mindful, and joyful learning, often referred to as full learning (FL3). This new approach aims to encourage students to have a more in-depth learning experience. However, this approach is still rarely studied in depth for physics learning. Therefore, this study was conducted with the aim of clearly visualizing the principles of FL3 in the field of education. Researchers used bibliometric analysis methods to visualize the data with VOSviewer and RStudio to identify co-occurrences, and MS Excel for descriptive statistical analysis. After collecting data from scopus, the results showed a significant increase in publications over the last ten years, particularly in 2019, when the initial research topic focused on educational technology but shifted over time towards contextual learning. From the three main dimensions of FL3, meaningful learning can be developed and applied through experiments and ethnoscience, mindful learning through reflective assessment, and joyful learning through gamification and experience-based activities. These findings confirm that FL3 has great potential to shape a physics learning model oriented towards deep understanding, reflective awareness, and continuous learning motivation in 21st-century education

Abstract

Physics education continues to face challenges due to students’ low levels of creative thinking skills (CTS) and the limited integration of problem-solving with gamification approaches in electromagnetic induction material. The research aims to describe significant differences in students’ CTS following problem-oriented gamification (POG) instruction supported by Electrical Monster Invaders (EMI), as well as students’ responses to the instruction. This research uses a quantitative experimental design involving one experimental class and two replication classes. Data collecting through CTS tests and student response questionnaires, analyzed using partial least squares structural equation models (PLS-SEM) to identify patterns of relationships among variables. The results indicate that POG-assisted learning using EMI effectively and consistently enhances CTS across all groups. Improvements were observed in every indicator. Structural analysis explains that POG plays a dominant role in shaping CTS, while the EMI serves as a supporting medium with an acceptable level of model fit. This study confirms that integration of problem-based learning, gamification, and interactive media is a relevant innovative strategy for enhancing CTS in physics learning (PL).

Abstract

Emotional maturity is a critical component of psychosocial development in elementary school children that requires systematic nurturing. Valid and reliable assessment instruments are therefore essential to objectively measure emotional maturity, enabling early identification and providing a scientific basis for designing mental health development programs, particularly in underserved communities such as children from the Madura ethnic group in Indonesia. Existing instruments are still limited in terms of item coverage, conceptual indicators, and suitability for the developmental characteristics of elementary school students. This study aimed to develop and validate a comprehensive instrument for assessing emotional maturity using a systematic Research and Development (R&D) method. The instrument was tested in two stages, namely expert validation through a Focus Group Discussion (FGD) and empirical testing involving 20 fifth-grade students at Cangkreng 1 Public Elementary School, Sumenep Regency, Madura. Content validity was analyzed using the Item-Level Content Validity Index (I-CVI) and Scale-Level Content Validity Index (S-CVI), while item validity and reliability were examined using SPSS and Cronbach’s Alpha. The FGD produced an S-CVI score of 0.993 for instruction, content, and language, showing a very high level of expert agreement. Item evaluation also resulted in an S-CVI score of 0.87, indicating strong content validity with only minor revisions. Empirical testing showed that all items obtained correlation values between 0.910 and 0.937, exceeding the critical value of 0.444 at α = 0.05. The Cronbach’s Alpha coefficient of 0.990 confirmed excellent reliability and internal consistency. These results indicate that the instrument is theoretically valid and empirically reliable for use by teachers, counselors, and researchers in assessing children’s emotional maturity.. Future studies should expand large-scale validation and integrate digital assessment systems to enhance scalability and innovation in child mental health monitoring.

Abstract

This study addresses the use of Facebook (FB) as a media for promoting science’ product. By adopting the concept of entrepreneurship education, the study explored the role of FB in promoting science message through “Learning Shirt-theme”. A thematic study was conducted, involving a group of Indonesian undergraduate physics students (34 members) in FB namely “Learning Shirt” and the content of their sites as the entrepreneurs and 192 active members as the service users. The students pursued their study at a public university in Surabaya, Indonesia, which contributed to the group’s community. These groups of students established entrepreneurship activities and promoted their message of physics via FB. The role of the researcher is a tutor of the community. Data analyses were used, including a thematic and documentation analysis and supported by questionnaire analysis. The results of the study categorized the physics-shirt into five themes: the history of physics, derivation of the equation in physics, physics symbols and equations, physics values, and models in physics. The FB users’ understanding of physics themes were in a good category with an average score of 79.79. The trend of FB user’s positive response regarding ten expressions in the questionnaire was increased significantly in three weeks.
