Abstract

This study is motivated by the importance of improving students’ conceptual understanding and scientific argumentation skills in chemistry practicum, particularly on the topic of acids and bases. It aims to evaluate the effectiveness of the Project-Based Learning (PjBL) model combined with the Evidence-Based Research (EBR) approach in supporting both aspects. This study employs a descriptive quantitative approach using a pre-experimental one-group pretest–posttest design The research subjects were 26 Chemistry Education students who participated in two cycles of practicum. Data were collected through a conceptual understanding test and report analysis using the Toulmin Argumentation Pattern (TAP) rubric, then analyzed descriptively. The results showed an increase in the average conceptual understanding score from 11.81 to 13.15, and the TAP score from 10.46 to 14.15. Most students demonstrated positive development in both aspects. These findings indicate that the PjBL–EBR model is effective in fostering scientific thinking, constructing data-based arguments, and engaging actively during the practicum. The implementation of this model is relevant for exploration-based practicums and is recommended for other chemistry topics. These findings indicate that the PjBL–EBR model is effective in encouraging students to think scientifically, construct evidence-based arguments, and actively engage during practicum activities. This model is considered relevant for exploratory-based practicums and has the potential to be applied to other chemistry topics.

Abstract

The alignment of the Chemistry Education Study Program curriculum structure at UIN Raden Fatah Palembang with the graduate profile as educational institution managers was evaluated in this study, and recommendations for curriculum reconstruction based on the graduate profile were developed. Despite growing demands for graduates who can take managerial roles in educational institutions, little empirical evidence exists on how undergraduate chemistry education curricula allocate credits, learning experiences, and assessment to develop managerial competence — this study addresses that gap. A qualitative case study approach was employed, in which curriculum documents, tracer study data, questionnaires, and interviews were analyzed for data triangulation. Of the total 146 credits in the curriculum, only 16 credits were found to explicitly support managerial competencies. The tracer study (n = 165 respondents) indicated that 16.4% of alumni were employed in educational institution management. A mismatch was identified between the formulation of graduate profiles and the allocation of curricular content, along with limited implementation of project-based learning and managerial internships. Recommendations were proposed, including: (1) the inclusion of courses on educational management and leadership; (2) the strengthening of project-based learning and MBKM internships within managerial pathways; (3) the application of authentic assessment and portfolio evaluation to measure managerial competence; and (4) the development of a phased blueprint for curriculum reconstruction. To our knowledge, this study’s novel contribution lies in empirically linking curriculum mapping, alumni tracer outcomes, and pedagogical practice to produce a context-specific, phased blueprint and concrete recommendations for a graduate-focused chemistry curriculum.

Abstract

This study explores traditional chemical practices within the Toraja community, an area of knowledge that remains underdocumented in existing scholarship. The research aims to: (1) describe chemical practices involved in the Rambu Solo’ funeral ceremony; (2) examine techniques for processing natural materials; and (3) discuss their pedagogical implications for chemistry education rooted in local wisdom. Using a qualitative ethnographic approach, the study was conducted in Tana Toraja and involved two purposively selected key informants: a teacher and a local cultural leader. Data were collected through in-depth interviews, direct observations, and documentation, then analyzed thematically. The analysis revealed two main themes. First, the use of pine leaves (Pinus merkusii) and tille wood in Rambu Solo’ functions as natural antiseptics and preservatives, a finding supported by literature on the bioactivity of terpenoids and phenolic compounds. Second, the fermentation of ballo’ and the production of natural dyes demonstrate biochemical processes and principles of green chemistry utilizing renewable natural resources. These findings show that Torajan traditional practices provide authentic and meaningful contexts for chemistry education. Incorporating such indigenous knowledge into the curriculum can make learning more relevant while helping preserve culture. Overall, this research offers an initial empirical basis for developing ethnoscience-based learning modules and suggests further studies involving quantitative chemical analyses and the development of innovative instructional materials. This approach can improve students’ scientific literacy and promote education for sustainable development.

Abstract

This study aims to reconstruct the ethnoscientific contexts of the Ciayumajakuning region (Cirebon, Indramayu, Majalengka, and Kuningan) into chemistry learning materials using the Model of Educational Reconstruction (MER) framework. A descriptive qualitative design was employed, integrating field surveys, literature review, and expert validation. Data were obtained from 17 respondents and scientific literature related to selected local wisdom contexts. The analysis identified five contexts with strong chemical relevance: batik Mega Mendung, wayang kulit, siraman panjang (jamasan), bata dan genteng Jatiwangi, and peuyeum ketan. Each was analyzed for its scientific structure and mapped against the high school chemistry curriculum within the Merdeka Curriculum framework. Results indicate that these local wisdoms represent diverse chemistry concepts, including organic and inorganic reactions, material transformation, and biochemistry, though their distribution across topics remains uneven. The study demonstrates that MER provides a systematic approach to transforming cultural practices into pedagogically sound learning contexts. The reconstructed models are expected to support the development of contextual, culturally responsive chemistry learning materials that strengthen students’ scientific literacy and appreciation of local culture.
