Abstract

Mathematics is a very abstract lesson and is always connected with numbers and formulas. Many students feel unhappy about mathematics and find difficulties in solving problems in the form of tables, stories, and diagrams. Learning method that can help students in improving mathematical communication and mathematical dispositions can be done through the application of discovery learning models. The purpose of this study was to determine the improvement of students mathematical communication and disposition abilities taught with discovery learning models. This study useda quantitative approach with the type of experimental research and the research design usedtrue pretest and posttest design type experiments. The population in this study were all eighth grade students of SMP N 2 Sigli. The sample was chosen randomly from two classes:classes VIII2 and VIII3. The research instrument used was mathematical communication ability test and mathematical disposition questionnaire. The data analysis of students communication and disposition ability was done by two-way ANAVA test at a significant level of 0.05. The results showed that the improvement of students mathematical communication and disposition skills taught with discovery learning models was better than those taught with conventional approaches. Furthermore, there wasno interaction between discovery learning model and the level of students towards improving communication skills and mathematical dispositions. Therefore, mathematics teachers in SMP N 2 Sigli who teach in class VIII can use discovery learning models in learning to build the next flat side space. Futureresearchers should conduct research at other schools in order to improve students mathematical communication skills in mathematics learning.

Abstract

Visual Basic Application for Excel is a simple program language and has the power to process data quickly, let alone the utilization of math functions in Microsoft Excel can help work on Excel display more interactive so that teachers can create props inside Excel. The advantages of Microsoft Excel compared to mathematical software are the many math functions and images available in the form of shapes or pictures. With the availability of VBA, math and image functions in Microsoft Excel, teachers can design the creation of media related to mathematics learning especially helping to develop the ability of junior high school students who have difficulty connecting mathematics lessons with basic mathematics knowledge requirements. In general, that most students in Indonesia have not solved mathematical problems, therefore, by using VBA for Excel the ability of junior high school students to improve in the usual way significantly with a t-test with 0.006 <0.05 and there is an association between Trust self-comfidence student with students mathematical comprehension skills with a contingency value with a significant amount of 0.016 <0.05 with a contingency coefficient of 0.525 including a moderate association.

Abstract

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. 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 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. 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

Students’ ability in expressing mathematical ideas in various ways is still not as expected. Teachers need to apply learning method that gives students the opportunity to express mathematical ideas based on their own mindset. Learning with the Brain-Based Learning approach assisted by Autograph software is expected to help students to grow their mathematical communication skills. This study aims to analyze the development of students mathematical communication skills. The subjects of this study were 28 students of class X in one high school in Banda Aceh. The instrument used was a mathematical communication ability test problem. Data analysis techniques was done using descriptive analysis. The results of the study showed that mathematics learning with an Autograph-assisted BBL approach can improve students mathematical communication skills.
