Abstract

Kemampuan koneksi matematis menjadi salah satu kemampuan yang sangat penting dan merupakan salah satu standar proses pembelajaran matematika yang dirumuskan oleh NCTM . Apabila peserta didik dapat mengaitkan konsep-konsep yang ada dalam matematika maka pemahaman terhadap matematikanya akan bertahan lama dan semakin mendalam. Penelitian ini bertujuan untuk mendeskripsikan kemampuan koneksi matematis peserta didik kelas VIII terhadap materi sistem persamaan linear dua variabel. Penelitian ini menggunakan metode penelitian kualitatif dengan pendekatan deskriptif. Prosedur penelitian dalam penelitian dimulai dari tahap persiapan, pelaksanaan, analisis data dan penarikan kesimpulan. Analisis data terbagi menjadi tiga tahapan yaitu reduksi data, penyajian data dan penarikan kesimpulan. Subjek penelitian diambil dari hasil pekerjaan peserta didik yang dikelompokkan menjadi 3 kategori tingkat kemampuan yakni tinggi, sedang dan rendah. Hasil penelitian ini menunjukan bahwa peserta didik berkemampuan tinggi dapat memenuhi semua indikator kemampuan koneksi matematis, peserta didik berkemampuan sedang kurang mampu pada indikator 1 dan 2 namun mampu pada indikator 3 kemampuan koneksi matematis, dan peserta didik berkemampuan rendah belum mampu memenuhi semua indikator kemampuan koneksi matematis. Mathematical connection ability is a very important ability and is one of the standard mathematics learning processes formulated by NCTMs. If students can link the concepts in mathematics, their understanding of mathematics will last longer and deepen. This study aims to describe the ability of mathematical connections class VIII students to the material system of linear equations of two variables. This study used a qualitative research method with a descriptive approach. The research procedure in the study starts from the preparation, implementation, data analysis and conclusion stages. Data analysis is divided into three stages, namely data reduction, data presentation and drawing conclusions. The research subjects were taken from the results of the students' work which were grouped into 3 categories of ability levels namely high, medium and low. The results of this study indicate that students with high abilities can fulfill all indicators of mathematical connection ability, students with moderate abilities are less able on indicators 1 and 2 but are able on indicator 3 of mathematical connection ability, and students with low ability have not been able to fulfill all indicators of mathematical connection ability .

Abstract

The Hatam tribe is one of the sub-tribes of the Arfak tribe. This study aims to explore the numeracy culture of the Hatam Tribe spoken by the Hatam Tribe community who inhabit Nuhuwei Village, Ransiki District. This research is ethnographic. The techniques used for data collection are interviews, exploration, literature study, desk study, and documentation. Interviews and explorations were conducted with several elders who spoke the Hatam language in Nuhuwei Village. Literature and documentation studies were conducted by looking for other sources of information related to the previously existing Hatam language to obtain accurate results. The Desk Study was conducted to find out the mathematical patterns of the Hatam Tribe. The results obtained from this study are that mathematically, the counting patterns spoken by the Hatam people who inhabit Nuhuwei Village have different dialects from the speech of the Hatam people who inhabit other areas. Besides that, another finding is that the pattern of mentioning numbers spoken by the Hatam tribe inhabiting Nuhuwei Village correlates with the counting pattern on the Jarimatika. We call this latest finding related to counting using the Hatam language-based Jarimatika as Himatam (Calculating Using Jarimatika in the Hatam language). This finding shows that learning numeracy for elementary students in Nuhuwei Village can be done more easily using the Himatam Method.

Abstract

The objective of this study is to create a case-method-based interactive e-module that will enhance the higher-level thinking skills (HOTs) of students. Research and Development (R&D) utilizing the ten-step Borg & Gall model development constitutes this research method. This investigation is restricted to the seventh stage. This study's participants were FKIP UNIPA first-semester students enrolled in instructional mathematics courses. The sample for the study was determined by cluster random sampling. The participants in this research were partitioned into two groups: the experimental group consisted of students majoring in English education, while the control group comprised students majoring in Indonesian language education. In this study, questionnaires, interviews, validator assessment forms, and HOTs tests were utilized to collect data. Three data analysis techniques were utilized in this study: validity, practicability, and effectiveness. The outcomes demonstrate the e-module's validity. The practicality assessment yielded an 81.44% response rate from students in the very practical category. The HOTs of the pupils in the experimental class were superior to those of the control class. The mean HOTs of students in the control group were 67.67, whereas those in the experimental group have an average HOTs of 75.50.

Abstract

Literacy skills mark the quality of human resources in a country. However, Indonesia's performance in literacy assessment on an international scale has not been very good. The results of interviews with teachers of SD Inpres 18 subsay Manokwari district on March 14, 2022 found the fact that students' numeracy literacy skills were still very low. This study aims to test the effectiveness of the problem-based learning model assisted by student worksheets to improve numeracy literacy skills in terms of the curiosity of elementary school students in Manokwari district. The approach used in the implementation of this research is a quantitative approach. This type of research is experimental research. Data collection techniques in this study are Numeration literacy test, Observation, Validation Sheet and Documentation. Data analysis includes data analysis of validity and effectiveness. The effectiveness data analysis includes the completeness test for numeracy literacy skills, the average difference test for numeracy literacy skills, testing the effect of curiosity character on numeracy literacy skills. The results of the Effectiveness Test Analysis show that problem based learning models assisted by student worksheets are effective in improving numeracy literacy skills by criteria: (1) The proportion of classical learning completeness can be said to be more than 75% of students getting a score of 65, (2) The numeracy literacy ability of students in classes that use problem based learning models assisted by student worksheets is better than students' numeracy literacy skills with conventional learning, (3) There is an effect of curiosity character (X) on posttest numeracy literacy ability (Y).
