Abstract

One problem in chemistry learning at the secondary and tertiary levels is the availability of appropriate learning resources. To address this problem, it needs contextual teaching materials to implement an ethnochemistry learning approach. This research aims to explore and develop the traditional potential of Samawa local wisdom as chemistry learning material. In addition, this study also explored resources that can be used in teaching chemistry. This qualitative research utilized literature studies, interviews, and documentation to collect the data and was analyzed using Miles & Huberman’s qualitative analysis. As for the sample used in this study were 10th grade students of SMAN 2 Taliwang. I use 2 classes, 1 class as the control class and 1 class as the experimental class.The community leaders, chemistry content experts, and relevant chemistry literature were selected as the study subject. Based on the findings, it can be concluded that Samawa’s local wisdom can be used as a source of chemistry learning through integration with Samawa culture on chemical bonding material. Therefore, this research is expected to be a reference in developing contextual chemistry teaching to create more significant and exciting learning since it is relevant to real-life experience.

Abstract

The implementation of the merdeka curriculum as an improvement and replacement for the previous curriculum needs to be studied on the structure and depth of its learning content. This study aims to describe the suitability of the content structure of chemical equilibrium material based on Bloom's Revised Taxonomy and university textbooks as standards. The research method used is descriptive qualitative to describe the object according to the data and information obtained. The research design uses the Model of Educational Reconstruction (MER) by Reinders Duit which focuses on Content Structure Analysis. The data analysis technique uses the Miles and Huberman model by collecting, reducing, presenting, and concluding data. There are research instruments: knowledge, skill, and attitude level analysis sheets, as well as content standard analysis of chemical equilibrium topic. The results of curriculum analysis show a deriving in operational verbs from the level of knowledge, skills, and attitudes based on the Pancasila profile. For content analysis, it is found that the depth and breadth of chemical equilibrium learning materials from the Cambridge book grade XI of the Ministry of Education and Culture and the University textbook by Brady are consistent but the development of the material sequence is different. The sub-chapter on equilibrium constants Kc and Kp should be the prerequisite material before learning the concept of equilibrium shift.
