Abstract

Jaring-jaring dapat membantu siswa membuat konsep hubungan antara objek dua dimensi dan tiga dimensi. Namun masih ada ketidakakuratan dalam menyusun jaring-jaring yang disebabkan oleh kemampuan spasial yang lemah. Tujuan dari penelitian ini adalah untuk menggambarkan kemampuan spasial siswa dalam membangun jaring-jaring kubus dan balok. Subjek penelitian adalah empat puluh siswa Sekolah Dasar kelas lima. Dari empat puluh siswa dipilih dua siswa untk diwawancara lebih mendalam terkait penyelesaian tugas jaring-jaring kubus dan balok. Hasil penelitian menunjukkan bahwa dalam menyelesaikan tugas penyusunan jaring-jaring kubus dan balok, subjek menunjukkan kelemahan dalam kemampuan orientasi spasial dan visualisasi spasial. Kelemahan pada orientasi spasial terlihat pada kemampuan subjek untuk melihat objek dari sudut pandang tertentu yaitu dalam mengenali dua jaring-jaring yang kongruen tetapi dianggap tidak kongruen. Sedangkan kelemahan visualisasi spasial nampak pada saat subjek yang tidak dapat membayangkan bahwa jaring-jaring dapat dilipat menjadi kubus dan balok. Nets can help students conceptualize the relationship between two-dimensional and three-dimensional objects. But there are still inaccuracies in composing the webs caused by weak spatial ability. The purpose of this study is to describe the spatial ability of students in constructing cube and beam webs. The research subjects were forty-fifth-grade elementary school students. Of the forty students, two students were chosen to be interviewed more deeply related to the completion of the task of the cube nets and the beam. The results showed that in completing the task of arranging cube and beam nets, the subject showed weaknesses in the ability of spatial orientation and spatial visualization. Weaknesses in spatial orientation are seen in the subject's ability to see objects from a certain point of view, namely in recognizing two nets that are congruent but considered incongruent while the weaknesses of spatial visualization are seen when subjects cannot imagine that the webs can be folded into cubes and blocks.

Abstract

This study aims to determine the effect of learning motivation on mathematics learning achievement of class VIII students of SMP Negeri 5 Tarakan, the effect of gender on mathematics learning achievement of class VIII students of SMP Negeri 5 Tarakan, and the effect of interaction between learning motivation and gender on mathematics learning achievement. VIII grade students of SMP Negeri 5 Tarakan. The type of research used is quantitative with a causal associative approach. The population in this study were all eighth grade students of SMP Negeri 5 Tarakan. Sampling was carried out using Proportionate Stratified Random Sampling. The sample in this study amounted to 163 students, including 88 male students and 75 female students. Data was collected using a questionnaire and score documentation. Data analysis technique used descriptive analysis and inferential analysis which was processed with the help of SPSS 24 application. Descriptive analysis used mode, while inferential analysis used Two Way ANOVA. Based on the results of the analysis with a significance level of 5% or 0,05, it can be concluded that: (1) there is an influence of learning motivation on mathematics learning achievement of class VIII students of SMP Negeri 5 Tarakan; (2) there is an influence of gender on the mathematics learning achievement of eighth grade students of SMP Negeri 5 Tarakan; (3) there is no interaction effect between learning motivation and gender on mathematics learning achievement of class VIII students of SMP Negeri 5 Tarakan.

Abstract

Mathematical communication skills are the main capital in solving math problems. Mathematical communication skills help students in conveying ideas or solutions to a mathematical problem in the form of oral, written, and picture. The research objective is to identify student errors in solving mathematical communication problems. The type of research is descriptive qualitative so that the researcher is the main instrument. Technical data analysis in this research is descriptive qualitative data analysis technique of Miles and Huberman model with stages of data reduction, data presentation, conclusion drawing and verification. The data reduction stage aims to select, focus, discard unnecessary data and simplify raw data from the results of student error analysis. The research subjects were students of class VIII A SMP Negeri 2 Tanjung Palas Utara. The research showed that the students did not make reading errors but made mistakes in understanding, transforming, processing skill, and solving mathematical communication problems.

Abstract

This study aims to find a substantive theory about learning a new paradigm for mathematics in the Vocational High School (SMK) curriculum in Bulungan District, North Kalimantan Province. To achieve this goal, the researcher chose a qualitative research method with a case study approach. The unit of analysis for this study is the school community (curriculum vice chief, mathematics teacher, and vocational students) who are carrying out the teaching and learning process at vocational schools. To obtain the necessary data, interviews, observations, and documentation analysis were carried out. The data obtained were then analyzed using the pattern matchmaking technique as recommended by Robert K. Yin. The findings of this study are that mathematics has a strategic position in the SMK curriculum. This strategic position is that there is a change in the position of mathematics from national content to the 2013 curriculum to vocational basics in the independent curriculum. In addition, learning mathematics in vocational schools still needs to be varied to achieve competencies that are expected to help students use facts, principles, concepts, and procedures that are relevant to their vocational skills.
