Abstract

This study aimed is to develop students’ soft skills through the implementation of the Culturally Responsive Transformative Teaching (CRTT) in chemistry learning. Indonesia's ethnic and cultural diversity is a challenge for teachers to design the chemistry lessons which is relevant with students’ characteristics. The research methodology applied is qualitative and applied on chemistry learning in the topics of acid and base, electrolyte and non electrolyte solution in five stages: self identification, cultural understanding, collaboration, critical reflections, and transformative construction. This research was conducted in two schools in DKI Jakarta and West Java in 2018. The data was collected by interview, reflective journal, and observations. The results showed that the chemistry learning through CRTT model can develop students' soft skills such as collaboration skills, critical thinking skills, nationality, social and cultural awareness, leadership, environmental caring, and curiosity. The teachers’ interview and reflections showed that the challenges in applying this approach were creativity in integrating cultural concepts in chemistry learning, students' understanding, time constraints, and the paradigm of students and teachers. Integration of ethnochemistry in CRTT can be developed in other chemical concepts with the principle of students’ character development

Abstract

Higher education quality assurance is aimed at quality education. Universities must systematically carry out the quality assurance process through the Higher Education Quality Assurance System and refer to the National Higher Education Standards. There are two quality assurance systems in higher education, namely; internal quality assurance and external quality assurance. The internal quality assurance system is a systemic activity of quality assurance of higher education by each university autonomously to control and improve the implementation of higher education in a planned and sustainable manner. Meanwhile, the external quality assurance system is an assessment activity carried out by outside units to determine the feasibility of universities. This study aims to fully describe two main things in the quality assurance system in higher education institutions, namely; internal quality assurance and external quality assurance. In obtaining this research data, a qualitative approach to the type of library research is used, by collecting data from books, journals and articles. Data analysis is carried out using content analysis. The results of the study found that: First, internal quality assurance includes: policies and procedures for quality assurance; approval, monitoring and periodic review of programs and awards; student assessment, quality assurance of teaching staff/lecturers; learning resources and student support; information systems; public information. Second, external quality assurance, namely: the use of procedures; process development; criteria for decisions; process in accordance with the purpose; reporting; follow-up procedures; periodic review of the implementation; and system-wide analysis

Abstract

Globalization influences various aspects, including education, so learning is needed to improve skills and quality of life abilities. This research aims to develop 21st-century skills through project-based learning (PjBL) and STEAM (Science, Engineering, Technology, Art, and mathematics). Participants in this study were 40 students in eleventh grade in the science program. This study used qualitative methods, which focused on the integration and implications of PjBL with the STEAM model on salt hydrolysis and buffer solutions. The STEAM project is a mockup of electrical conductivity and water purification on salt hydrolysis and hydroponic plant cultivation for projects on buffer solution—data collection techniques through interviews, reflective journals, classroom observations, and teacher diaries. The results showed that students were interested and motivated in making STEAM projects. 21st Century skills consisting of life and career skills can be seen from the initiative and a sense of responsibility in doing projects, learning and innovating skills seen from student creativity and innovation, and technology skills seen through marketing project creative ideas through information media and technology. Other implications, such as curiosity, motivation, and confidence, arise in the learning process. Based on its integration and implications, the STEAM approach with PjBL can be used as an alternative to improve 21st-century skills in chemistry learning

Abstract

The increasing adoption of digital beauty technology through Virtual Try-On (VTO) platforms powered by artificial intelligence (AI), augmented reality (AR), and virtual reality (VR) necessitates a precise understanding of user preferences. This study aims to model user responses to VTO features using Item Response Theory (IRT), specifically the Graded Response Model (GRM) for ordinal-scale items and the Nominal Response Model (NRM) for non-ordinal categorical items. A total of 15 items were analyzed using GRM to assess users’ perceptions of AI accuracy, feature convenience, and visual satisfaction. Additionally, five non-ordinal items were modeled using NRM to capture explicit preferences for specific VTO functionalities, such as digital interaction and visual simulation. The results show that the average user preference score was 3.02 out of 5 (SD = 1.03), while the total preference score averaged 60 out of 100 (SD = 10.7), with response distributions approximately normal (skewness = 0.12; kurtosis = -0.24). The item information curves from the GRM indicated that several items contributed high information (above 2.0), effectively differentiating users within the −1 to +1 ability range. In the NRM analysis, the “real-time color visualization feature” exhibited the highest utility parameter (c = 1.98), indicating a strong user preference for this feature. The integration of GRM and NRM enables a more nuanced and flexible mapping of user preferences. This study presents a novel psychometric approach by combining GRM and NRM within a single VTO context to simultaneously capture both ordinal and nominal dimensions of user experience, which has not been extensively explored in prior research. These findings provide meaningful insights for the development of adaptive, personalized, and intelligent AI-based VTO systems to enhance the quality of user experience in digital beauty applications.
