Virtual Laboratories in Science Education: A Systematic Review of Effectiveness on Conceptual Understanding and Learning Outcomes
Get PDFVirtual laboratories (VLs) have emerged as a significant innovation in science education, enriching learning experiences, deepening conceptual understanding, and providing more flexible and safer access to experiments. Nevertheless, the implementation of VLs still faces challenges, particularly in developing practical skills and ensuring integration with physical laboratories. This study aims to present a comprehensive review of the impacts, potentials, and limitations of VLs through a systematic literature review. The method employed follows the PRISMA protocol, with Scopus as the primary database. Out of 489 initial articles, only 21 articles met the inclusion and exclusion criteria after the screening process. The analysis was directed toward two main research questions: (1) to what extent does the use of interactive simulation–based virtual laboratories enhance conceptual understanding, and (2) how do students’ learning outcomes compare with those of traditional laboratory practices? The findings revealed that the development of VLs is typically grounded in constructivist approaches and instructional design models that emphasize the creation of interactive experiences that resemble real experiments. Furthermore, the results suggested that students taught using VLs achieve better learning outcomes compared to those taught through traditional methods. VLs have been shown to support improvements in conceptual understanding, laboratory skills, scientific literacy, questioning ability, analytical thinking, and cognitive performance, all of which contribute to strengthening critical thinking skills. Thus, VLs not only serve as a solution to the limitations of physical facilities but also play a crucial role in fostering critical thinking as one of the key competencies of the 21st century. Keywords: virtual laboratory, science education, and learning outcomes.
Enhancing Science Literacy and Collaboration Skills Through the RADEC Learning Model in Junior High Schools
Get PDFCollaboration and science literacy skills are key indicators in the current learning era. Collaboration trains students to actively engage and make decisions together, while science literacy equips them to think critically and face the challenges of the Industrial Revolution. However, in reality, both skills remain below average among students. This gap highlights the need for an effective learning model to address the problem. Several studies have shown that the Read, Answer, Discuss, Explain, and Create (RADEC) learning model can improve these abilities through a structured and student-centered approach. The objectives of this study are to analyze the effectiveness of the RADEC learning model in improving students' science collaboration and literacy. This research used a quasi-experimental nonequivalent control group design. The sample consisted of class VIII C (experimental) and VIII D (control), selected through purposive sampling. Data were obtained from a collaboration skills questionnaire and students’ pretest and posttest scores to assess improvements in science literacy skills. The results showed that (1) the RADEC model is effective in improving students' science collaboration skills from the t-test with sig (2-tailed)-value is less than 0.05 which means that the structured RADEC model can facilitate the development of affective and cognitive aspects to create a high collaborative learning environment and (2) the RADEC model is effective in improving students' science literacy skills from the t-test with sig (2-tailed)-value is less than 0.05 which means that the RADEC model through its stages is able to build better conceptual understanding to develop students' science literacy significantly. This study concludes that the RADEC learning model is effective in improving the science collaboration skills and science literacy of junior high school students. Keywords: RADEC, science collaboration skill, science literacy
Microteaching Frequency and the Development of Teaching Skills and Pedagogical Content Knowledge among Prospective Mathematics Teachers
Get PDFThe teaching skills developed by prospective teachers are often repeated in different situations. Therefore, the optimal frequency of microteaching practices may influence both teaching skills and pedagogical content knowledge. This study used a cross-sectional design to compare teaching skills and pedagogical content knowledge among groups based on the frequency of microteaching practices conducted by prospective mathematics teachers. A total of 79 students were randomly selected from three universities in Yogyakarta that implemented microteaching with varying frequencies. These frequencies were classified into four categories: once, twice, three times, and more than three times. Teaching skills were assessed using observation sheets that outlined aspects such as explaining skills, asking questions, providing guidance, providing reinforcement, managing whiteboard use, and regulating body movement (non-verbal cues). Pedagogical content knowledge was measured using a test instrument. Data were analyzed using descriptive statistics and a one-way ANOVA test. The results showed that the frequency of practice has a different impact on teaching skills and pedagogical content knowledge. Prospective teachers who practiced microteaching more than three times significantly differed in their explaining skills, while their providing reinforcement differed significantly from those who practiced at least three times. Conversely, prospective teachers who practiced twice performed similar levels of skill in asking questions, whiteboard management, and regulating body movement compared to those who practiced more frequently. Pedagogical content knowledge of prospective teachers who practiced more than three times was significantly higher than that of those who practiced three or fewer times. These findings suggest that universities should carefully regulate the frequency of microteaching practices to optimize students' teaching skills and pedagogical content knowledge in mathematics education for those who aspire to become effective mathematics teachers. These findings suggest that universities should carefully regulate the frequency of microteaching practices to optimize students' teaching skills and pedagogical content knowledge in mathematics education students who aspire to become effective mathematics teachers.

Achieving Future Competencies: Integrating Project-Based Learning and Simulation to Develop 21st Century Skills
Get PDFThis study aims to develop students' skills through the integration of project-based learning and simulation. This study used mixed methods by involving 30 students of the Mathematics Education Study Program at Universitas PGRI Sumatera Barat as research subjects. Data collection was conducted through observations of five meetings and semi-structured interviews with nine students of various academic ability level, including high, medium, and low. The research instrument for quantitative data was an observation sheet, while for qualitative data, a semi-structured interview sheet was used. The data obtained were analyzed using descriptive statistical analysis techniques for quantitative data and thematic analysis for qualitative data. The results of the study showed that the students' skills were not evenly distributed. Group collaboration in learning proved to be successful in increasing cooperation skills up to the high category, which indicates the effectiveness of learning in creating active interactions between students. However, other skills, such as creativity, communication, critical thinking, and innovation, are still in the medium category, which indicates that they still need further improvement and development. This study concludes that the integration of project-based learning and simulation has a positive effect on the abilities of students with uneven abilities. The integration of these learning approaches works synergistically by effectively linking theory and practice. Through project-based learning, students are encouraged to take an active role in designing, managing, and completing projects that directly contribute to their skill development. On the other hand, simulation functions as a complement that strengthens the effectiveness of project-based learning by presenting a real representation of the project by visualizing abstract concepts and allowing students to test the solutions they develop based on the project results.

Analysis of Pre-service Mathematics Teachers' Representational Ability Regarding the Prime Numbers Concept
Get PDFA deep understanding of prime numbers remains a significant challenge, particularly for pre-service mathematics teachers responsible for conveying this essential knowledge to their students. Prime numbers have an essential role in mathematics, including in factorization, proof, and cryptography. Therefore, this study aims to describe and analyze the representational abilities of prospective mathematics teacher students at Alkhairaat University, regarding the prime numbers in Number Theory. This study uses a descriptive exploratory method with a mixed-methods approach based on a sequential explanatory design. Data collection was carried out through diagnostic tests, semi-structured interviews, and documentation, which were then analyzed using descriptive statistics for quantitative data and the Miles & Huberman model for qualitative data. Triangulation of methods and time was used to ensure the validity of the data. The findings showed that out of 17 students, only 29.41% were able to provide accurate verbal representations related to the prime and composite numbers, and only 5.88% were able to link the two meaningfully. In addition, while students were able to mention definitions, most of them had difficulties applying the prime numbers in the abstract problem context, including examples in algebraic notation. This study concludes that there is still a significant gap in the representation ability of prime number concepts of pre-service mathematics teachers. The implications emphasize the need for integrating multidimensional representation learning strategies into the mathematics education curriculum so that prospective teachers are better prepared to teach prime numbers in a comprehensive and meaningful way. Keywords: representation, prime numbers, number theory, pre-service mathematics teachers
