Abstract

Research on the transformation of traditional scientific knowledge into scientific science in the production process of traditional herbal medicine. This study aims to transform the original scientific knowledge of the Muara Putus community regarding traditional herbal medicine into scientific science. The benefits expected from this research are as a learning resource or learning model. This research method is descriptive qualitative, in which the researcher is directly involved in the research arena by conducting interviews, discussions, direct observation and studying documents related to traditional herbal medicine, as well as scientific literature related to traditional herbal medicine compounding. The focus of the research is the culture of making traditional herbal medicine focused on the knowledge of herbal medicine sellers regarding the manufacture of herbal medicine, how to mix the herbs, the types of herbal medicine made, and their benefits. The conclusion of this study is that there is some genuine scientific knowledge from herbal medicine sellers that can be explained by scientific science, including the process of making herbal medicine, the ingredients used and the benefits of each herbal medicine.

Abstract

A concise the purpose of the study was to determine the effectiveness of the flipped classroom model on the problem solving skills of science education students. A total of 950 studies were analyzed obtained from six databases consisting of ScienceDirect, Education Resources Information Center (ERIC), Wiley Journal, Springer; ProQuest and IEEE aim to get relevant articles published in 2020-2023.  From the analyzed studies, 21 studies were selected for meta-analysis.  Data analysis with JSAP software.  The results showed that the flipped classroom model provides high effectiveness on the problem solving skills of science education students (rRE = 0.97; 95 % CI [0.840; 1.111]; p < 0.001). This finding provides information for teachers to apply the flipped classroom model to improve students' problem solving skills in learning

Abstract

Despite growing policy demands for Higher Order Thinking Skills (HOTS) assessment in Indonesian science education, psychometrically validated instruments aligned with the Merdeka Curriculum remain scarce. This study aims to develop and validate a HOTS-based assessment instrument for eighth-grade junior high school (SMP) science students. Employing the Research and Development (R&D) approach with the 4-D model (Define, Design, Develop, Disseminate), the instrument was designed to comprehensively measure HOTS at cognitive levels C4 (Analyzing), C5 (Evaluating), and C6 (Creating) of the Revised Bloom’s Taxonomy, covering Basic Competency (BC) 3.8 (Respiratory System) and BC 3.9 (Photosynthesis) topics. The instrument consists of 40 two-tier multiple-choice (TTMC) items and 10 essay items. Content validity was assessed by three experts using Aiken’s V formula, yielding a mean V of 0.87 (highly valid). Reliability was estimated using the KR-20 formula in a large-group trial (n = 64), producing a coefficient of 0.82 (reliable), and Cronbach’s alpha of 0.79 for essay items. Item analysis encompassed difficulty index, discriminating power, and distractor effectiveness. Results showed that 34 of 40 TTMC items (85%) met all quality criteria simultaneously: moderate difficulty, good discriminating power, and effective distractors. The final instrument (34 TTMC + 10 essay items) is valid and reliable for measuring higher-order thinking skills among SMP students. The TTMC format provides added diagnostic value by revealing specific conceptual misconceptions in addition to measuring HOTS proficiency, aligning with the formative assessment emphasis of the Merdeka Curriculum.
