Abstract

Problem solving is one of the abilities that students must have in the 21st century. This is because students' ability to solve problems is expected to increase their higher order thinking skills (HOTS) competency. The ability to measure problem solving can be assessed through test instruments in the form of questions containing problems. This research aims to analyze problem solving abilities in colloidal materials through the development of the IDEAL Problem Solving assessment instrument. This instrument includes five indicators, namely Identify the Problem, Define the Outcome, Explore Possible Strategies, Anticipate Outcome & Act, and Look back and Learn. The research was conducted for 3 months at SMAN 1 Sungai Tabuk class XI semester II (even). The method used is development research or R&D (Research and Development) research. The development of this instrument adapts the ADDIE development model by following five steps, including (1) Analyze (analysis), (2) Design (planning), (3) Develop (development), (4) Implementation (implementation), (5) Evaluate (evaluation). Data analysis was carried out quantitatively with statistical tests. The empirical validity results show that the instrument is valid and reliable to use and meets the criteria for a good level of difficulty and discrimination.

Abstract

Critical thinking skills are high-order thinking skills in which students are required to solve complex problems. The topic of reaction rate has conceptual knowledge, cognitive skills, and psychomotor skills that can be used to assess and develop students' critical thinking skills. This study aims to analyze the critical thinking skills of science eleventh graders on reaction rate. This research applies the survey research method. As the research instrument, it uses a critical thinking skills test on the reaction rate consisting of 27 multiple choice questions with a reliability of 0.756 by involving 153 public senior high school students. The authors develop this test. The results show that the average score of respondents’ critical thinking skills was 33.66 (low category). At the sub-skill level, the average score of respondents' skills in interpreting was 32.73 (low), analyzing was 29.04 (low), inferencing was 36.77 (low), evaluating was 24.61 (low), and explaining was 33.88 (low). This shows that the learning experiences of the students have not been able to develop their critical thinking skills. Therefore, this research suggests the need for a learning strategy that can be used to improve students' critical thinking skills.

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

Entrepreneurship is increasingly recognized as an essential skill for students to face global economic and social challenges. However, research on entrepreneurial self-efficacy (ESE) among high school students in Indonesia remains limited, despite its crucial role in shaping entrepreneurial intentions and readiness. This study aims to explore students’ levels of ESE and analyze the influence of gender and entrepreneurial experience on their abilities and intentions. Using a mixed-methods approach, data were collected through surveys measuring knowledge, interest, experience, and ESE. The findings reveal that students have high levels of entrepreneurial knowledge and interest, with ESE ranging from moderate to high. Gender was found to influence knowledge, interest, and ESE, with female students tending to demonstrate stronger entrepreneurial intentions. Moreover, prior entrepreneurial experience was shown to enhance both ESE and students’ interest in entrepreneurship. Qualitative analysis highlighted that students perceive capital, marketing, and product development as key needs for entrepreneurship, while common challenges include competition and financial constraints. Overall, students expressed neutral to positive sentiments toward entrepreneurial engagement. These findings underscore the importance of practical, gender-sensitive, and experiential entrepreneurship education to strengthen ESE and better prepare students for the challenges of the business world.

Abstract

This study aims to explore the challenges, strategies, and impacts of implementing Project-Based Learning (PjBL) in the Analytical Chemistry program at Vocational High Schools (SMK). Using a qualitative phenomenological approach, data were collected through interviews, observations, and documentation involving teachers and students actively engaged in PjBL activities. The analysis followed Moustakas’s phenomenological steps, including data reduction, categorization, and interpretation. The findings revealed three key themes: (1) resource and infrastructure limitations, (2) teachers’ adaptive and innovative strategies, and (3) students’ creativity and entrepreneurial motivation. Despite facing financial and facility constraints, teachers demonstrated resilience by utilizing local resources, modifying learning designs, and applying reflective assessment. Students, in turn, showed high creativity and problem-solving skills by developing innovative chemical-based products that integrated environmental awareness and entrepreneurship. The study concludes that PjBL effectively enhances students’ higher-order thinking, creativity, and motivation in vocational chemistry learning. However, its sustainability depends on institutional support, adequate funding, and collaboration with industry. These findings highlight the importance of developing structured, project-based digital modules to strengthen teacher competence and ensure meaningful, future-oriented learning in vocational education.

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
