Abstract

For the Kefamenanu community, the motif serves as the identity of the person who wears it. Nevertheless, the woven fabric must be present at cultural occasions, welcoming guests, and death ceremonies. The motifs of traditional woven fabric have not been developed by teachers to discuss the link between mathematics and local wisdom. The purpose of this research is to define and describe the mathematical concept of the motifs woven fabric to the students of primary and junior high schools. The present study uses a descriptive qualitative method to explain the geometry concept on the motifs of woven fabric. The ethnographic approach is also employed as an empirical and theoretical approach to provide description and analysis about a culture based on intensive field work. Collecting data were conducted using interviews and documentation. Interviews were conducted with several informants selected based on the consideration of researcher and suggestion by previous informant. Documentation was done using video recordings and photos. The results show the geometry concept of the motifs of woven fabric, such as reflection, rotation, translation, repetition, triangle and quadrilateral. The motifs of woven fabric owned by the Kefamenanu community contain particular local wisdom and are potentially used to convey the geometry concept in mathematics for primary and junior high schools.

Abstract

An exploration of factor analytic structure of the conceptions of mathematics scale among pre-service mathematics teachers in South-West Nigeria was conducted as evidence suggests paucity of research on psychometric properties of the conceptions of mathematics scale in Nigeria.This article through instrumentation research methodology reports the reliability and validity of the Conceptions of Mathematics Scale based on the responses of 228 pre-service mathematics teachers from five public universities in South-West Nigeria. The reliability assessed as internal consistency produced a Cronbach alpha of .88. A principal components exploration with varimax gyration established the validity of the scale as two-component archetypal accounting for 48.9% of the total variance. The dimensions were taken as Patchy Formations and Unified Formations of mathematics, as explicated in the original and other replicating studies. The factor solution could be compared to that recounted in the previous studies; hence the outcome showed the need to adopt the scale in the Nigerian context, as the pedagogy implemented during the teaching and learning of mathematics can influence students’ conceptions of mathematics. Thus, teaching mathematics with rules-based and algorithm-dependent teacher-centered pedagogies might result into rote memorization thereby leading to patchy formations while teaching mathematics as a meaningful subject full of applications to the real life could engender conceptual understanding leading to unified formations. The implication of this study is that students with patchy formation are connected with surface approaches to learning while those with unified formation of mathematics are connected with deep approaches to learning and engaging mathematics.

Abstract

This study aim to describe the student’s mathematics anxiety on the use of technology in mathematics learning. It is a quantitative descriptive research by involving second year students of Mathematics Education Program  in Universitas Islam Riau (UIR) who took Technology-based Mathematics Learning course. They were selected based on saturation sampling. Data were collected through questionnaire, in-depth interview and documentation. The results show the high level of each dimension of mathematics anxiety among students. The average score in each indicator of cognitive, affective, and physiological dimension were high. In addition, interview revealed that most of the students expressed their anxiety in the first lecture and when obtained the task of applying particular software in mathematics learning. It is mainly due to unpreparedness and lack of knowledge about the application of software. Based on the results, it can be concluded that the level of students’ mathematics anxiety is relatively high.  Keywords: Mathematics anxiety, Technology-based, Mathematics learning,

Abstract

Similarity is a topic in Geometry which investigates similar elements of a plane. This topic has a high complexity that generates cognitive load in working memory. A deep understanding of the concept is needed to solve similarity problems. Based on cognitive load theory, learning by goal-free problems is suggested since it can minimize cognitive load. This research examined the effectiveness of presenting similarity inquiries using goal-free problems for learning by collaboration. Using a factorial design: 2 presentation techniques (goal-free vs. goal-given problems) x 2 groupings (collaborative vs. individual) in authentic classrooms, the experiment consisted of four consecutive phases: introductory, learning phase, retention test, and transfer test. One-hundred eleven eighth-graders from four classrooms in a junior high school in Yogyakarta, Indonesia, served as research participants. The findings showed that students who were learning using goal-free problems possessed significantly higher scores of retention and transfer tests, as well as experience lower cognitive load during both tests. On the contrary, it was found that studying individually yielded a significantly higher transfer score than studying collaboratively. Since there was no interaction effect, it may be concluded that goal-free problems can be effective for either collaborative or individual learning.

Abstract

Proof is a key indicator for a student in developing mathematical maturity. However, in the process of learning proof, students have the difficulty of being able to explain the proof that has been compiled using good arguments. So we need a strategy that can put students in the process of clarifying proof better. One strategy that can explore student thought processes in explaining geometric proof is self-explanation strategy. This research aimed to analyze the ability to understand the geometric proof of prospective teacher students by implementing a self-explanation strategy in basic geometry classes. This study used a quasi-experimental research type of nonequivalent control group design. The participants of this research were 75 students of mathematics education study programs at one private university in Semarang. This research used four instrument tests of geometric proof. Before being used for research, the instruments were tested for validity and reliability using product-moment and Cronbach's alpha. Data analysis in this study used a two-way ANOVA test. The results showed that: the increased ability to understand the geometric proof of students who used self-explanation strategy was better than those who obtained direct learning; there was a significant difference between the increase of students’ mathematical proof ability in a group of students with a high and moderate level of initial mathematical ability; the initial ability (high, medium, low) of mathematics did not directly influence the learning process to improve the ability to understand the geometric proof. Hence, it can be concluded that the self-explanation strategy is effective to be used to improve the understanding of the geometric proof.

Abstract

One of the cultural outcomes of the Madurese community is the traditional tanean lanjang house with a long front yard, designed from several batih (nuclear) families, consisting of a married couple with unmarried children. This study explores geometric concepts of the traditional house to demonstrate how they can be useful for learning mathematics. The descriptive qualitative study described the mathematical concepts found in the tanean lanjang traditional house or settlement in Madura. Furthermore, an ethnographic method was also used to analyze documents, ethnographic notes, and documentation (photos). Data analysis techniques employed an interactive model of data collection, data reduction, data presentation, and conclusion. The results of the study show that the cultural values and geometric concepts of the tanean lanjang traditional house comprised (1) kinship and brotherhood values, (2) harmony in the household, and (3) strength in the household. The geometric concepts contained in the traditional tanean lanjang house include 2-dimensional shape (i.e., rectangle, trapezoid, triangle), perimeter of 2-dimensional shape, area of 2-dimensional shape, 3-dimensional shape (i.e., triangular prism), the volume of 3-dimensional shape, curve, and the concept of reflection in geometry.
