This study was intended to investigate the influence of inquiry learning approach assisted with square word media toward students’ mathematical understanding ability in learning mathematics. This study was conducted through quantitative research procedures namely quasi-experimental design. The populations were all students of class X at MAS Syamsuddhuha. The samples were 25 students of class X MIA 1 and 25 students of class X MIA 2, selected by purposive sampling. The nonequivalent posttest-only control group design was used. The data were obtained from the post-test results of the students’ mathematical understanding; they were analyzed by using SPSS 18 software. Since the data was not normal, the non-parametric Mann-Whitney test was applied. The findings of this study showed that the significant value of the test was 0,000 and it was less than 0.05 allowed the H0 rejected. It can be concluded that there was an influence of inquiry learning approach assisted by word square media on students' mathematical understanding ability, which was done in the study of trigonometry II for class X at MAS Syamsuddhuha. Hence, mathematical understanding ability is a crucial aspect in solving mathematical problems which can be measured by applying inquiry learning approach in classroom.

Kemampuan pembuktian matematis merupakan kemampuan penting dalam pembelajaran matematika. Namun, kemampuan tersebut menjadi salah satu kemampuan yang sulit dikuasai siswa. Untuk mengatasi hal itu, perlu dikaji faktor-faktor yang memengaruhi kemampuan tersebut. Oleh karena itu, penelitian ini dilakukan untuk melihat faktor-faktor yang memengaruhi kemampuan pembuktian matematis. Kuesioner diberikan kepada 30 siswa kelas X salah satu SMA Swasta di Kota Bandung yang baru selesai belajar proses pembuktian matematis. Masing-masing butir pernyataan diberikan skor dan diurutkan dari skor tertinggi ke rendah, selanjutnya beberapa butir pernyataan tersebut dikelompokkan ke dalam faktor baru berdasarkan urutan skor. Hasil menunjukkan faktor pengalaman menjadi faktor terkuat bagi siswa dalam memengaruhi kemampuan pembuktian matematis. Faktor berikutnya adalah faktor kemampuan, faktor waktu, faktor sikap dan motivasi, serta faktor guru.

Assessment Kompetisi Minimum (AKM) is an assessment of the basic competencies possessed by students on a national scale. One of the skills required to participate in the AKM is numeracy literacy. To train these abilities, students must get used to working on numeracy literacy questions. However, at SMP Negeri 2 Rantau Selatan which is located in Labuhanbatu, the treasury of numeracy literacy questions is still lacking and those that use the socio-cultural context of Labuhanbatu do not yet exist. So it is necessary to develop numeracy literacy questions using the socio-cultural context of Labuhanbatu. The purpose of this study was to determine the validity of the results of developing numeracy literacy questions using the socio-cultural context of Labuhanbatu and to determine the numeracy literacy skills of students using these questions. The questions referred to the Minimum Competition Assessment (AKM). The type of this research is Design Research type Development Study which has been modified. This research consists of a stage preliminary, self-evaluation, expert review, and field test. Based on the validation from the validator, all questions can be used for field tests. The results of the field test consist of 14 questions with the criteria "very adequate for use", 2 questions with the criteria "adequate for use", and 1 question with the criteria "considered for use". All questions are included in the final product. The final product is used to see the students' numeracy literacy skills. The percentage of students' numeracy literacy skills is 3% "high" and 97% "low". The average percentage of students who answer questions at the cognitive level of knowing, applying, and reasoning are 50% and 32%, respectively. and 18%.

Kemampuan pembuktian matematis merupakan bagian dari kemampuan penalaran matematis. Salah satu tujuan pembelajaran matematika di Indonesia adalah untuk meningkatkan kemampuan tersebut karena berfungsi untuk melatih kemampuan berpikir matematis tingkat tinggi. Kemampuan pembuktian matematis terdiri dari dua sub-kemampuan, yaitu kemampuan memahami bukti matematis dan kemampuan mengonstruksi bukti matematis. Salah satu topik matematika SMA yang sarat dengan pembuktian matematis adalah trigonometri. Penelitian ini dilakukan untuk mengetahui apakah kemampuan memahami bukti matematis berpengaruh terhadap kemampuan mengonstruksi bukti matematis. Sebuah tes yang terdiri dari 4 soal kemampuan memahami bukti matematis dan 3 soal kemampuan mengonstruksi matematis diberikan kepada 30 siswa kelas X di salah satu SMA Kota Bandung. Skor siswa dianalisis secara statistik. Hasil analisis regresi sederhana menunjukkan bahwa kemampuan siswa dalam memahami bukti matematis berpengaruh secara signifikan terhadap kemampuan mengonstruksi bukti matematis. Hasil tersebut mengisyaratkan bahwa guru selama proses pembelajaran matematika seharusnya tidak hanya fokus untuk meningkatkan kemampuan mengonstruksi bukti matematis tetapi juga harus fokus dalam meningkatkan kemampuan siswa dalam memahami bukti matematis.

Kurangnya kegigihan dalam penyelesaian masalah membuat siswa terlihat sukar menyelesaikan masalah yang berbeda, hal ini menyebabkan rendahnya kemampuan berpikir kreatif matematis siswa. Untuk itu penggunaan model Problem Based Learning (PBL) berbantuan GeoGebra diharapkan meningkatkan kemampuan berpikir kreatif matematis siswa. Adapun penelitian ini bertujuan untuk melihat peningkatan kemampuan berpikir kreatif matematis siswa yang diajarkan melalui model Problem Based Learning (PBL) berbantuan GeoGebra lebih baik daripada siswa yang diajarkan melalui pendekatan saintifik di SMA Negeri 1 Muara Batu. Penelitian ini merupakan penelitian quasi experimental design dengan menggunakan desain penelitian nonequivalent control group design. Populasi dalam penelitian ini adalah siswa kelas XI SMA Negeri 1 Muara Batu tahun ajaran 2019/2020 dan sampel penelitian adalah siswa kelas XI MIPA 2 sebagai kelas eksperimen dan siswa kelas XI MIPA 3 sebagai kelas kontrol yang dipilih secara purposive sampling. Data diperoleh dari hasil tes instrumen kemampuan berpikir kreatif matematis siswa berupa tes pretest dan postest serta dianalisis uji normalitas, homogenitas, dan uji hipotesis berbantuan software SPSS 25. Hasil penelitian menunjukan bahwa peningkatan kemampuan berpikir kreatif matematis siswa yang menggunakan model pembelajaran Problem Based Learning berbantuan GeoGebra lebih baik dari pada siswa yang belajar menggunakan pendekatan saintifik di SMA Negeri 1 Muara Batu.
