This study aimed to find out what were the activities of ethnomathematics on the Tapis cloth that can be used as a source of mathematics learning. The data obtained are qualitative data with data sourced from observation and participant observation (fieldwork), interview and questioner, document and text, impression, and the reaction of the researcher. The technique of validity was using triangulation. The result of the research showed that from several kinds of Tapis cloths: 1) They had a philosophical sense on every Tapis motif related to the Lampung people's existence. 2) Two activities exist in Tapis Lampung that was measuring activity and counting activity. 3) Mathematical concepts on Lampung filters include One-dimensional geometry found in the star's motifs that applied the line concept. The two-dimensional geometries were triangles, rhombus, and elliptical rectangles derived from Tapis Pucuk Rebung, swaying headers, stylish headlines, and geometric motifs. Transformation Geometry concept of Reflection and Rotation was on mangosteen flower and leafflower. Dilatation was on the rhombus motif. The translation was on the motives of humans and riding animals.   Penelitian ini bertujuan untuk mengetahui apa saja aktivitas etnomatematika pada kain tapis yang dapat dijadikan sebagai sumber belajar matematika.

Abstraction Levels

Whole-half-quarter are important mathematical concepts that form the basis of fractions and should be well understood for advancing mathematical topics. The aim of this study is to determine the primary school students' abstraction levels of whole-half-quarter concepts according to RBC theory. The participants of the study are six students (8 age group) from the second grade of primary school. The data of the research which is a case study were collected through worksheets and semi-structured interviews. The data obtained from interviews were analyzed by qualitative data analysis steps. The abstraction levels of students were evaluated according to RBC theory. As a result of the study, it was seen that many of the students could not abstract the whole, half and quarter concepts. It was determined that difficulties of students to abstract the whole-half-quarter concepts resulted from reasons such as not understanding the half and quarter concepts, not being able to divide the whole into two equal parts, not being able to divide one dimensional shapes into half and quarter, generalizing dividing into quarter as putting a "+", not being able to divide into four equal parts for quarter.

Mathematics Competence

Purpose: Mathematics is a globally compulsory school subject and plays a fundamental role in an individual’s daily life activities. Elementary school teachers’ instructional practices are key in fostering among learners the foundational competences in basic number operations. This study explored the instructional practices Primary One teachers in Busiro North and Luuka North Counties can adopt from each other in order to enhance their learners’ mathematics competence.Methodology: A qualitative approach with an observational multiple case study design was employed to obtain data from 74 purposively selected teachers. Data was collected through non-participant observation. Each teacher was observed teaching mathematics to Primary One learners and interviewed after the lesson. Data obtained was analysed descriptively.Findings: Findings indicate that teachers use songs, rhymes and games involving mathematical concepts, in both English language and the local languages   to help learners attain competence. Teachers have also embraced use of locally available materials like woven plastic propylene bags (buveera) and banana fibres to make and decorate charts in the classrooms’ mathematics learning areas. Attention grabbers like “Good children, Good teacher”; “We, Work”; are common verbal interactions between teacher and learners when the class seems to lose concentration. Teachers recognise learners’ efforts when they correctly answer oral, written or practical tasks by asking the class to give a classmate “flowers” or “the pa-pa-pa clap”.Unique contribution to theory, practice and policy: For teachers to help learners’ master mathematical concepts and augment their competence, they should build on learners’ experience and prior knowledge, give learners opportunities to explain their mathematical ideas and use the think – pair – share strategy during problem solving.

The mathematical concept on cultural objects is one of the objects of study in the study of ethnomathematics. This study aims to uncover mathematical concepts in the ornaments found in the rumah gadang and the development of ornaments. This qualitative research uses participatory observation techniques and documentation to obtain data. The results showed that there were geometrical concepts in the ornaments and the development of the rumah gadang ornaments. The concepts of geometry seen in ornaments include the use of two-dimensional such as square, rectangular, rhombic, circle, ellipse and polygons. Two-dimensional shape are also arranged using certain patterns. The development of ornament forms is carried out using the principles of congruence, tessellation, symmetry patterns and geometric transformations (translation, reflection, rotation, and dilation). The results of this study can be used as a reference for teachers in mathematics learning and ethnomathematics research on cultural objects.Keywords: ethnomathematics, ornaments of rumah gadang

“Dynamical mixing”, i.e. relaxation of a stellar phase space distribution through interaction with the mean gravitational field, is numerically investigated for a one-dimensional self-gravitating stellar gas. Qualitative results are presented in the form of a motion picture of the flow of phase points (representing homogeneous slabs of stars) in two-dimensional phase space.
