Abstract

Virtual 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.

Abstract

Representational competence is very essential for students because it is associated with the students' ability to use, interpret, translate and integrate chemical representations to understand chemical concepts properly. In this case, implementation of the various representations utilization is required in learning Thermochemistry to improve students' representational competence to fully understand Thermochemistry. Therefore, this study aims to analyze teachers' perceptions towards the understanding and implementation of chemical representations in chemistry learning to improve students' representational competence in thermochemistry. This research is a descriptive quantitative research conducted using survey method that involved 30 chemistry teachers. The sample in this study was taken by purposive random sampling at public and private high schools in East Java. The data were collected through a questionnaire using google form application. According to the results of the study 63.3% of teachers still have difficulty in teaching students the concept of thermochemistry using submicroscopic representations. The majority of teachers only use symbolic representations, even though the other two representations are very important. Although 77% of teachers have understood chemical representations, in teaching and measuring concept understanding, teachers have not integrated chemical representations. This is due to their lack of self-awareness about the importance of using various representations in improving students’ representational competence. Thus, training on representations is necessary in improving teachers’ understanding on chemical representations. The findings of the study stated that teachers’ understanding of representation and teachers’ experience in participating in the trainings contributed to the effectiveness of the implementation of various chemical representations utilization to improve students’ representational competence on the concept of thermochemistry.       Keywords: representational competence, chemical representation, and thermochemistry.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1559-1576
