Abstract

Students' obstacles in learning mathematics are due to weak reasoning and low motivation. This study aims to develop a metacognitive learning model using the metaphor of a rare Kalimantan tree to improve mathematics learning outcomes and motivation. The research method comprised the Recursive, Reflective, Design, and Development stages, with the learning model developed as a single-path prototype and validated through expert, small-group, and field validation. The instruments include expert assessments, student response questionnaires, mathematics achievement tests, and motivation scales. Data analysis used qualitative and quantitative descriptions, bar charts, line charts, and analysis of variance. The research findings are presented through the gradual development of the learning model from a single-path prototype to an alpha and beta version. The learning model, in the form of a single-path prototype, is a rough draft for organizing three components: metacognitive questions, metaphors, and hands-on activities. The alpha version of the learning model was developed through expert and small-group validation. Experts assess the learning model as very effective for mathematical reasoning and learning motivation, and easy to apply. The beta version of the learning model has been proven effective in improving mathematics learning outcomes and in the interaction effect between motivation and the learning model during the mathematics learning process. Teachers use it by creating worksheets with metacognitive questions and assigning hands-on activities. The results of this study contribute theoretically by highlighting elements of local wisdom as components of the model.   Keywords: hands-on activity, mathematical reasoning, metaphor, metacognitive questioning strategy, motivation.

Abstract

The low mathematical literacy of Indonesian students based on PISA results necessitates innovation in mathematics learning. This study aims to analyze the effectiveness of peatland-based digital comic media (Electronic comic of Peatland/E-colands) in improving junior high school students' mathematical literacy and to reveal the dilemma of improving mathematical literacy occurring in grades VII, VIII, and IX. The research method used was quantitative with a pretest-posttest group design. The research sample consisted of 23 grade VII students, 26 grade VIII students, and 26 grade IX students selected using a purposive sampling technique. Data were collected through mathematical literacy tests in descriptive form and analyzed using descriptive statistics, followed by t-test and n-gain score analysis. The results showed that E-colands media was effective in improving mathematical literacy with a medium improvement category in all classes (n-gain: VII=0.68; VIII=0.41; IX=0.55). However, a dilemma was found where the significant improvement only changed the literacy criteria from low to medium in class VII, while classes VIII and IX remained in the low category even though their scores increased. This dilemma indicates the presence of cumulative learning loss, differences in psychological and motivational factors, and the need for longer and more integrated interventions for holistic mathematical literacy improvement.

Abstract

The importance of reflective thinking skills in mathematics learning stems from in their demand for students to analyze, evaluate, and reconsider problem-solving strategies. The objectives of this study are: (1) to describe students' mathematical reflective thinking abilities based on discovery learning activities, and (2) to identify the factors that influence students' mathematical reflective thinking abilities. This study employed a mixed-method approach with an explanatory sequential design. Quantitative data were obtained through observations of the implementation of discovery learning, while qualitative data were gathered through tests and interviews with two students. The results show that students who effectively followed the stages of discovery learning tended to demonstrate a high level of mathematical reflective thinking. The research subjects were able to exhibit all three indicators of reflective thinking (reacting, comparing, and contemplating). Factors influencing students’ reflective thinking skills include cognitive aspects based on Bloom's taxonomy: knowledge (C1), comprehension (C2), application (C3), analysis (C4), and evaluation (C5).

Abstract

This research aims to Identify each type of plant that has the potential to be used as medicine in Petak Puti Village; Describe the use and processing methods of plants that have the potential to be used as medicine. The research uses a qualitative method with a descriptive research design. Observation, to obtain information about the initial stages of the research, was conducted to seek information about traditional medicine that utilizes medicinal plants in Petak Puti Village. The informant selection technique used the purposive sampling method, carried out by selecting informants for certain considerations, in this case, the person who is considered to know the most about the situation in the village. The determination of informants purposively is assumed that the selected informants represent a homogeneous community, consisting of main informants (key informants) to be interviewed such as the village head, traditional leaders and immigrants who are married to village residents. While the basic informants are village members, traditional members and residents outside the village who have knowledge about the village. The local wisdom of plant species is very significant in the views and perceptions of the community in meeting basic human needs. The Dayak Ngaju Katingan community is highly dependent on natural resources to meet various daily needs. Most of the community's income comes from forest plant products. The diversity of plant species can provide food products for the community, produce various types of plants for consumption as a supplement for the Dayak community and generate alternative sources of income, such as used as food, medicines, fermentation, tonics, cosmetics, building materials and other materials, which can provide important nutrients and vitamins as supplements for the community, and can provide a buffer in times of food shortages. In addition, existing plant species have great potential to be developed and cultivated into new plants and provide genetic resources and conduct selection.

Abstract

Low mathematical literacy among Indonesian students, as indicates by PISA results, highlights the need for innovative and contextual learning media that connect mathematics with real-life situations. This study aimed to develop and examine the feasility and praticality of E-Colands (Electronic Comic of Peatlands) as a mathematics learning medium for junior high school students in Central Kalimantan. The research employed a research and development method using the ADDIE model, limited to the Analysis, Design, Development, and Implementation stages. E-Colands was designed as a digital comic integrating matematical literacy tasks with peatland contexts encountered in students’ daily lives. Product feasibility was assesed through expert judgment by material and media experts using Likert-scale validition instruments. Practicality was evaluated through student response questionnaires administered to 75 students from grades VII, VIII, IX selected through purposive sampling. The results showed very high level feasibility, with validation scores of 91.25% form material experts and 89.29% from media experts. Students responses indicated good practicality, with an overall score of 80.49%, expecially in language clarity, media design, and ease of use. These findings suggest that E-Colands is a valid and practical learning medium to support contextual mathematics learning and enhance students’ mathematical literacy.
