The people of Tengger, Indonesia have used plants as traditional medicine for a long time. However, this local knowledge has not been well documented until recently. Our study aims to understand the utilization of plants in traditional medicine by the people of Tengger, who inhabit the Ngadisari village, Sukapura District, Probolinggo Regency, Indonesia. We conducted semi-structured and structured interviews with a total of 52 informants that represented 10% of the total family units in the village. The parameters observed in this study include species use value (SUV), family use value (FUV), plant part use (PPU), and the relative frequency of citation that was calculated based on fidelity level (FL). We successfully identified 30 species belonging to 28 genera and 20 families that have been used as a traditional medicine to treat 20 diseases. We clustered all the diseases into seven distinct categories. Among the recorded plant families, Poaceae and Zingiberaceae were the most abundant. Plant species within those families were used to treat internal medical diseases, respiratory-nose, ear, oral/dental, and throat problems. The plant species with the highest SUV was Foeniculum vulgare Mill. (1.01), whereas the Aloaceae family (0.86) had the highest FUV. Acorus calamus L. (80%) had the highest FL percentage. The leaves were identified as the most used plant part and decoction was the dominant mode of a medicinal preparation. Out of the plants and their uses documented in our study, 26.7% of the medicinal plants and 71.8% of the uses were novel. In conclusion, the diversity of medicinal plant uses in the Ngadisari village could contribute to the development of new plant-based drugs and improve the collective revenue of the local society.

Rigorous questions in discussion learning method plays a dominant role in the successful delivery of lessons for slow learners at higher education. This study aims to propose a framework to achieve good critical thinking for slow learners through Rigorous Mathematics computational Thinking (RMcT) model. This study used qualitative approach to describe slow learner’s critical thinking by using RMcT model. The instruments used in this study were test instrument, critical thinking questionnaire, and interview guideline as supporting instrument to describe slow learner’s critical thinking through RMcT model. The subjects were college students in mathematics modelling course in mathematics education department. Based on critical thinking test results, slow learners could divide variable used in mathematics modelling. Based on questionnaire results, slow learner students build their own understanding and solve the problem based on their experience while answering the given question during learning process. In addition, the interview they feel that the instructor can mediated the problem by giving analogy to the other material. In summary, RMcT could mediate slow learner’s critical thinking as its characteristics (by using Rigorous questions). Findings are useful for designers, service providers and policy makers of special needs higher school when implementing teaching strategy to mediated real-life problems into mathematics modelling for slow learners.

Many students still possessed misconceptions and not yet know the relation between each quadrilateral, no exception blind students that have abnormal physiological structures. Lack of student’ ability in relational thinking makes it difficult to construct analytic definitions that contain the closest type (genus proximum) and special differentiator (differentia specifica) on the objects. The aim of this study is to investigate the misconceptions of blind students in constructing the analytic definition of a quadrilateral using geometry’s puzzles. Misconception investigations focus on misconceptions of students’ concept or differences of student’ scientific understanding with the expert conceptions, especially misconception in constructing analytic definitions. This research is an exploratory study with a qualitative approach and the subjects of this study are one seventh grade student who experienced totally blind and one student who low vision from MTs Yaketunis Yogyakarta. Data collection through task-based interviews and observations. Before being analyzed, the obtained data then transcribed, classified, reduced and validated using the time triangulation method. Based on the results of data analysis, it is known that both of blind students have misconceptions namely classificational, relational and theoretical misconceptions with the level of misconception in low vision student lower than totally blind.
