Abstract

Objective: Based on previous research, there is evidence that science literacy and technological literacy in various regions of Indonesia still need improvement, especially vocational high schools. Science literacy and technological literacy in science learning are combined with socioemotional abilities, one of which is the ability to empathize students. Learning interventions are needed to produce competitive graduates who are able to compete in facing challenges in the world of work. This study aims to validate the STEM Empathy learning model. Method: The educational development research design used is a validation study design that tests two criteria, namely testing content validity (also called relevance) and construct validity (also called consistency). This validation involved three experts in the field of Science Education, and the validation instrument used a validation sheet. Result: The research results and data analysis showed that the Empathy STEM learning model consistently provided highly relevant results and met strict validity and reliability standards (with a percentage of agreement ≥ 75%). Novelty: Validation of learning support devices includes lesson plans, student textbooks, learner worksheets, science literacy and technological literacy tests. Empathy STEM learning can be applied to improve students' science literacy and technological literacy. The empathy stem learning model can train scientific literacy and technological literacy while fostering students' socio-emotional abilities. STEM learners are well-suited to teaching empathy, social emotional learning into science education creating a holistic STEM that s the potential to increase students’ interest and appreciation of science and its applications.

Abstract

This study explores the influence of a Stark-like perturbative potential on a quantum particle confined to a cylindrical surface (QPCS) and its implications for extra-dimensional theories. The QPCS framework is particularly relevant to Kaluza-Klein (KK) theory, which postulates extra spatial dimensions to unify electromagnetism and gravity. In KK theory, these extra dimensions are typically hidden and require high-energy conditions for detection. Motivated by the challenge of uncovering these dimensions more feasibly, this research applies a perturbative potential of the form ĤSL = βzV₀z(θ) to a QPCS characterized by length L and radius R₀. This potential is inspired by the Stark effect in hydrogen atoms, where energy level splitting serves as an indicator of an external influence. The study demonstrates that, for a degenerate configuration (R₀ = L/π), the Stark-like perturbation effectively induces energy level splitting, which can be interpreted as a means of revealing hidden dimensions. The first-order energy correction in this scenario depends explicitly on the quantum numbers nz and nθ, highlighting the potential for this approach to probe extra-dimensional effects in lower-energy quantum systems.
