Abstract

This study aims to determine and analyze the quality of learning by applying oral feedback in Problem Based Learning model to students' mathematical reasoning abilities. This research used a mixed method research. The population is X grade of SMA Negeri 8 Semarang. The sample selection used probability sampling technique with X MIPA 4 as the experimental class and X MIPA 5 as the control class. Based on the data analysis, the average value of the final test of mathematical reasoning ability in the experimental class was 76.05 with the completeness of the proportion 88.5%. The results of the analysis found that students' mathematical reasoning abilities could be categorized into 3, namely high, medium, and low according to the abilities of each student. Giving oral feedback to students also gives a positive response, so that giving oral feedback can improve students' mathematical reasoning abilities.Penelitian ini bertujuan untuk mengetahui dan menganalisis kualitas pembelajaran dengan menerapkan oral feedback dalam model Problem Based Learning terhadap kemampuan penalaran matematis siswa.

Abstract

Each child has their own characteristics, including mild mentally retarded students. There are several ways to help the mild mentally retarded students in learning mathematics. One of the ways is by using square geometry puzzle media. This study aimed to explore the learning process of mild mental retardation students in solving division count operations using square geometry puzzle media. The research design was an exploratory case study of 2 male mild mentally retarded students in a special school in Indramayu Regency. Data collection techniques used in this were used observation, interviews, and documentation which were analyzed by using data analysis techniques from Bogdan and Biklen. The research findings illustrated that the use of square geometry puzzle media can make students more active and expressive. It was because there was body movement that makes students do not feel bored in the learning process. In addition, according to the ability of students in solving division questions, it is found that mentally retarded students are able to solve division questions until the numbers divided that reached 30 and 40.Setiap anak memiliki karakteristik sendiri, termasuk siswa tunagrahita ringan. Banyak cara yang bisa dilakukan untuk membantu siswa tunagrahita ringan belajar matematika. Salah satu cara yakni menggunakan media kotak puzzle geometri. Fokus penelitian ini mengeksplorasi cara siswa dalam menyelesaikan soal operasi hitung pembagian bilangan bulat sampai 40 menggunakan media kotak puzzle geometri.  Desain penelitian menggunakan exploratory case study terhadap 2 siswa tunagrahita laki-laki di salah satu SLB di Kabupaten Indramayu. Teknik pengumpulan data dalam penelitian ini menggunakan observasi, wawancara, dan dokumentasi yang dianalisis menggunakan teknik analisis data dari Bogdan dan Biklen. Hasil temuan penelitian menggambarkan bahwa penggunan media kotak puzzle geometri dapat membuat siswa menjadi lebih aktif dan ekspresif. Hal tersebut karena semua anggota badan bergerak dan tidak menimbulkan kebosanan dalam mengikuti proses pembelajaran. Selain itu, jika dilihat dari kemampuan siswa dalam menyelesaiakan soal pembagian diperoleh bahwa siswa tunagrahita mampu menyelesaikan soal pembagian sampai angka yang dibagi mencapai 30 dan 40.

Abstract

Tujuan penelitian ini adalah untuk mengkaji kemampuan berpikir kreatif dilihat dari perbedaan gender pada Blended Learning berbantu Google Classrooms (BL-GC). Penelitian mix methods dilakukan dengan strategi concurrent embedded dimana subjek penelitian dipilih dengan teknik purpose sampling sehingga diperoleh 5 mahasiswa laki-laki dan 5 mahasiswa perempuan. Untuk meninjau kemampuan berpikir kreatif digunakan tes dan wawancara. Hasil penelitian menunjukkan bahwa implementasi BL-GC efektif terhadap kemampuan berpikir kreatif tanpa melihat perbedaan gender. Hal tersebut diperoleh berdasarkan hasil temuan secara kualiatatif dan kuantitatif yang menyebutkan bahwa kemampuan berpikir kreatif, peningkatan kemampuan berpikir kreatif, dan ketercapaian indikator kemampuan berpikir kreatif tidak berbeda secara signifikan. Temuan lain menunjukkan bahwa kefasihan merupakan langkah awal dari kemampuan berpikir kreatif, sehingga jika ingin mengembangkan kemampuan berpikir kreatif, maka langkah awalnya adalah mengembangkan kefasihan siswa.The aim of this study was to examine creative thinking skills viewed by gender differences in Blended Learning with Google Classrooms assisted (BL-GC). The mix methods research was carried out with a concurrent embedded strategy. The research subjects consist of 5 male and 5 female students. To review differences in creative thinking skills, tests and interviews are used. The results showed that the implementation of BL-GC was effective on creative thinking skills regardless of gender. This was obtained based on the qualitative and quantitative findings which stated that creative thinking skills, gain creative thinking skills, and the achievement of creative thinking skills’s indicators did not differ significantly. Other findings show that fluency is the first step in the ability to think creatively, so that if you want to develop creative thinking skills, the first step is to develop student fluency.

Abstract

Penelitian ini bertujuan untuk menguji efektivitas kegiatan Klinik Matematika dalam meningkatkan kemampuan dasar matematika siswa SMA. Penelitian ini merupakan penelitian eksperimen semu dengan desain desain pretest-post-test non-equivalent group. Subjek penelitian ini adalah siswa kelas XI SMAN 12 Berau, yaitu masing-masing 31 orang sebagai kelas eksperimen dan kontrol. Instrumen penelitian yang digunakan adalah soal pretest (α = 0,800) dan post-test (α = 0,800) masing-masing sebanyak 30 butir berbentuk isian singkat. Skor pretest dan post-test diolah dan disajikan dengan statistik deskriptif. Selanjutnya ditentukan n-gain dari kedua kelas, lalu dilakukan uji beda sampel independen. Hasil penelitian menunjukkan bahwa peningkatan skor siswa dari kelas eksperimen lebih tinggi daripada kelas kontrol. Setelah dilakukan uji hipotesis, gap peningkatan pada kedua kelas tersebut signifikan secara statistik (p(0,033) α(0.05)). Dengan demikian, disimpulkan Klinik Matematika meningkatkan kemampuan dasar matematika siswa SMA secara signifikan.This study was aimed to examine the effectiveness of the Klinik Matematika in improving the basic mathematical abilities of high school students. This research is a quasi-experimental study with a non-equivalent group pretest-post-test design. The subjects of this research were students of 11th grade of SMAN 12 Berau, there are 31 students each as the experimental and control group. The research instrument was a short answer pretest (α = 0,800) and post-test (α = 0,800) which consist of 30 items. Pretest and post-test scores were analysed and presented with descriptive statistics. Then the n-gain of the groups is determined, so an independent sample test can be performed. The results showed that the improving in student scores from the experimental group was higher than the control group. After hypothesis tested, the gap of the two groups was statistically significant (p (0.033) α (0.05)). Thus, it was concluded that the Klinik Matematika significantly improved the basic mathematical abilities of high school students.
