Abstract

Misconceptions in solving story problems involving the System of Linear Equations of Two Variables (SPLDV) are often a challenge for students. This research aims to identify the types of misconceptions experienced by students of grade VIII of Kasih Yobel Junior High School in Singkawang in solving SPLDV story problems, which are studied from the perspective of numeracy literacy. This research used descriptive qualitative method involving six students as research subjects. Data were collected through diagnostic tests and interviews to identify misconceptions based on numeracy literacy components: understanding, use, interpretation, and communication. The results showed that students experienced several types of misconceptions, especially in the translation of story problems into mathematical form, the use of strategies/methods, and calculations. The misconceptions were caused by students' lack of understanding of the basic concepts of SPLDV and inability to apply mathematical symbols and operations correctly. The discussion of the research results emphasizes the importance of learning approaches that strengthen students' numeracy literacy, especially in terms of understanding concepts and applying effective strategies. The conclusion of this study shows that improving numeracy literacy needs to be a priority in mathematics teaching to reduce misconceptions and improve students' ability to solve SPLDV story problems.

Abstract

Biology interest is a defining characteristic that shapes the identity of biology teachers and guides their pedagogical decision-making in the classroom. Recognizing the importance of this attribute in both current and prospective biology teachers, this study aimed to develop and validate the Biology Interest Instrument (BII) to support the sustainability of professional teacher education. The BII was designed to capture five core dimensions: approaches to learning biology, application of biology instruction, assessment practices, teacher characteristics, learning environment, and the nature of the biology curriculum. The development process involved input from biology education experts across 11 Indonesian institutions through focus group discussions. To assess the instrument’s validity and reliability, data were collected from 855 prospective biology teachers and analyzed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The final instrument comprises 32 items across five dimensions, all demonstrating acceptable psychometric properties. The BII is recommended for use in teacher education programs, particularly in Indonesia and other developing countries, to identify and foster biology interest in future educators.

Abstract

Science learning in secondary schools often struggles to explain abstract concepts such as biological mechanisms and cellular processes, which are difficult for students to visualise using conventional teaching methods. This condition contributes to low conceptual understanding and limited technological literacy among students. To address this issue, this study developed science microlearning media designed in short, interactive, and focused learning units. This study aimed to identify the characteristics of science learning in secondary schools, determine the validity of the developed microlearning media, and examine their effectiveness in improving students’ conceptual understanding and technological literacy. The study employed a research-and-development method that included needs analysis, product development, expert validation, and feasibility testing. The validation results showed that the developed media achieved a very high validity score, with a content score of 4.52. Feasibility assessments also demonstrated high acceptance with average scores of 4.47 and 4.51, respectively. These findings indicate that the developed microlearning media are feasible and have strong potential to support science learning, particularly in facilitating students’ understanding of abstract concepts. Future studies are recommended to conduct broader experimental investigations and integrate advanced technologies to enhance the scalability and effectiveness of microlearning media.

Abstract

This study aims to review and synthesize research trends on the application of virtual laboratories in physics education published between 2015 and 2025. It focuses on identifying dominant themes, research directions, and emerging opportunities in integrating digital technologies into physics learning. A systematic literature review approach was employed by selecting articles from Scopus-indexed journals and conference proceedings. Relevant studies were identified using keywords related to virtual laboratories, physics education, and digital learning. The selected articles were analyzed using bibliometric and thematic analysis to map publication trends, author contributions, and keyword co-occurrence patterns. The results indicate a significant increase in publications on virtual laboratories, particularly during and after the COVID-19 pandemic. Authors from Indonesia emerged as the most prolific contributors in this field. The dominant themes in virtual laboratory research were closely associated with distance learning and digital technology, reflecting the growing reliance on online and hybrid learning environments. Additionally, virtual lab studies were frequently linked to broader educational themes, including e-learning, curriculum development, and STEM education. Despite these developments, the integration of advanced technologies, such as artificial intelligence, remains limited and represents a strong area of potential for future exploration. Virtual laboratories have become an essential component of physics education, supporting flexible and interactive learning environments. However, current research remains largely focused on basic digital integration rather than on intelligent or adaptive systems. Future studies are recommended to explore the incorporation of artificial intelligence and more advanced pedagogical frameworks to enhance the effectiveness and personalization of virtual lab experiences. Keywords: virtual lab, systematic literature review.

Abstract

This study aims to see how effective the implementation of the Republic of Indonesia National Police Regulation Number 1 of 2021 concerning Community Policing by the Community Police Partnership Forum in Tekarang District is?, and what are the supporting and inhibiting elements in the implementation of the Regulation?. This study uses empirical law, which is a legal research method with a field research approach or factual conditions that occur in the social environment. To obtain data, researchers use observation and interview guidelines. Based on the results of the study, it was found that the application of the law to the Republic of Indonesia National Police Regulation Number 1 of 2021 concerning Community Policing by the Community Police Partnership Forum in Tekarang District has not been implemented effectively, and that the supporting factors include: the legal factor itself, law enforcement factors and community factors, while the inhibiting factor is the law enforcement factor which is only limited to the formation of the Community Police Partnership Forum (FKPM), but there is no work program. In addition, the facility factor is the absence of the Community Police Partnership Center (BKPM) and the factor of minimal public awareness and understanding of FKPM and community policing.
