Abstract

Modern ethnomathematics is proposed in this article by introducing curves and surfaces to objects based on commonly used mathematics. There are 2 types of objects, batik and ornament. The object is known as Batima, which means a mathematical motif made in a batik stamp. The same design can be used to design ornaments, souvenirs, accessories or other household items such as glasses, t-shirts and other materials. The formation of ethnomathematics is driven by entrepreneurial activities. The method starts with the expansion of the circular and spherical equations based on the variation of the power form which was originally 2 in the equation to be valued at random (say p). The other used equations are parametric equations, especially the hypocycloid which is extended to both curves and surfaces with spherical coordinates. In addition, derivative operators can be applied. Product manufacturing is carried out by at least 10 household businesses around Salatiga and Jogjakarta and its surroundings. In order to sustain the mainstreaming of modern ethnomathematics, entrepreneurial activities are carried out with existing materials through exhibitions and competitions that are followed. Likewise, the use of social media and marketplaces are explored to mainstream the modern ethnomathematics into society.

Abstract

Literatures revealed that the cognitive and affective components are the factors affecting problem solving. In this article we identified factors considered by the students in learning mathematical problem solving. Using a descriptive phenomenological research we identified the lived experiences of forty-five (45) students in solving a mathematics problem. Following the Colaizzi method for data analysis, four themes emerged: emotions and self- efficacy as affective factors, and group learning activity and teacher- student relationship as social factors. Sixty items from these four themes were further explored in using an Exploratory Factor Analysis (EFA) for a new set of 200 students. These four-factor structures of the students experiences in mathematics problem solving explained 66% of the variance in the pattern of relationships among the items. All four-factor structures had high reliabilities (all at or above Cronbachs α > .904). The study exemplified that teacher- student interaction relationship during learning activities, which is a social factor, provides the highest correlated factor that influences the mathematical performance of the students.

Abstract

This study aims to develop a learning trajectory by utilizing the local wisdom of the Megono Gunungan tradition to help students grasp the sphere's notion. This research applied the approach of the Indonesian Realistic Mathematical Approach (PMRI). Ninth-grade students at SMP 38 Semarang, Central Java, Indonesia, were the subjects of this study. The methodology used is based on Graveimeijer and Cobb's three steps of design research: preliminary design, design experiment, and retrospective analysis. Numerous data collection methods were used, involving video, photography, the outcome of students' worksheets, and student interviews. The learning trajectory comprises four activities: identifying sphere components using the Megono Gunungan tradition interactive video context, discovering the sphere surfaces area using orange fruit, finding the sphere's volume through rice media, and solving problems of the sphere. This study's findings signify that the utilization of the Megono Gunungan tradition context could encourage learners to recognize the concept of the sphere through a sequence of designed activities.

Abstract

Present study investigated the effectiveness of the use of technology software-based instruction in learning Circle Geometry, the extent of the students' interest on the use of this strategy, and designs a classification model through Discriminant Analysis forcasting students' performance as to having mastered or not the lessons based on their interest on the use of the strategy. The study utilized single subject research design to the thirty-one Grade 10 students in Llamera National High School, Dinagat Islands Division. Trend analysis and repeated ANOVA results revealed that most students' performance in circle geometry improved throughout the intervention of technology software-based instruction and the gap between the high achieving and low achieving students was reduced. Students also perceived high interest in learning geometry through the intervention. Indeed, technology software-based instruction recuperates knowledge in Circle Geometry. Accordingly, the capability to visualize the lesson through the software-based instruction is the best predictor of the students' mastery in circle geometry.

Abstract

Curriculum 2013 that is currently being implemented in Indonesia, still holds many obstacles in its implementation. One of them is the constraints in making a lesson plan. Some tools can help teachers create better lesson plans, one of which is a tool called Curriculum Review Mapping System (CRMS). This research aims to find out the results of national curriculum analysis in mathematics in high school using CRMS and also teacher response to these results. This study used descriptive methods with a qualitative approach. The instruments used are documentation, interviews, and researchers themselves. CRMS uses a technology called a mapping system to analyze the curriculum. The description of the national curriculum analysis results is contained in the result and discussion section. CRMS can be used as a teacher lesson plan analysis tool as teacher preparation before the teacher presents his/her learning in the classroom.

Abstract

Mathematical concepts will be embedded if they can be imagined and appear in everyday life. Therefore, this study aims to develop Local Instructional Theory in context-based matrix learning. Design research is adopted to achieve these objectives. The design research has three stages, namely, preliminary experiment, teaching experiment, and retrospective analysis. The study was conducted at a high school on the outskirts of the capital, involving 39 students of class XI. The data was collected employing tests, observation, interviews, worksheets, and documentation in the form of video recordings, photos, and student journals. The results indicated that students were able to construct their concept of matrices through the context of a favorite or a hobby as a starting point in compiling and defining a matrix, and continued with the matrix multiplication concept (matrix scalar multiplication as repeated addition; terms and products of two matrices).

Abstract

Many ethnomathematical studies examine the existence of mathematics concepts in Indonesian cultural products where batik is one of them. However, there is a lacunae from previous studies that examine the existence of mathematical concepts in Batik Sidoluhur. Therefore, the current study aims to explore mathematical concepts in Batik Sidoluhur, such as geometry, algebra, arithmetic, and statistics. The study used ethnography as an approach by answering four principal questions, namely "where do I start looking?", "how do I find it?", "how do I recognize that it has found something significant?" and "how to understand what it is?". By answering the questions, researchers managed to examine the mathematical concept contained in Batik Sidoluhur. From the four mathematical concepts explored, namely geometry, algebra, statistics, and arithmetic, only the concept of geometry is contained in Batik Sidoluhur and has been confirmed by a geometry expert. Sub-concepts of geometry found are (1) sub-concepts of geometry transformations such as translation and reflection, (2) plane geometry such as rhombuses, rectangles, triangles, and circles, and (3) congruence. It is hoped that the results of this study can be used as materials to promote Batik Sidoluhur to the younger generation through contextual and meaningful mathematics learning. In this article also explained how to use the context of Batik Sidoluhur in mathematics learning.
