Abstract

Abstrak: Penelitian ini bertujuan untuk mengetahui efektivitas masing-masing kategori model pembelajaran, motivasi belajar siswa dan interaksinya terhadap prestasi belajar matematika siswa. Populasi dalam penelitian ini adalah seluruh kelas VIII SMP Negeri 5 Madiun yang terdiri dari 4 kelas. Penentuan sampel menggunakan cluster random sampling. Metode pengumpulan data yang digunakan adalah metode tes dan metode angket. Uji hipotesis penelitian ini menggunakan anava dua jalan sel tak sama dengan taraf signifikansi 0,05. Kesimpulan dari hasil penelitian ini adalah (1) prestasi belajar matematika siswa yang menggunakan model pembelajaran Artikulasi lebih baik dari model pembelajaran Talking Stick, (2) jika ditinjau dari masing-masing tingkatan motivasi belajar, siswa yang memiliki motivasi belajar tinggi prestasi belajarnya jauh lebih baik dibandingkan dengan siswa yang memiliki motivasi belajar sedang maupun rendah dan (3) model pembelajaran Artikulasi lebih efektif dari model pembelajaran Talking Stick untuk meningkatkan prestasi belajar siswa, untuk setiap tingkat motivasi belajar siswa.Abstract:  The aims of this research were to find out the effectivennes of each categories of learning model, motivation to study and their interaction towards student mathematics learning achievement. The population was all students of grade VIII Five Junior High School of Madiun City consisted of four class. Sampling was done by cluster random sampling technique. The hypothesis test used unbalanced two ways analysis of variance at the significance level of 0.05. The conclution of this research that (1) the model of Articulation learning gives a better mathematics achievement than model of Talking Stick learning, (2) students with the high motivation to study had better achievement than students with the medium and low motivation to study, and (3) the model of Articulation learning was more effective than the model of Talking Stick learning to enhance students mathematics learning achievement for each level of students motivation to study.

Abstract

Abstrak: Penelitian ini merupakan penelitian deskriptif kualitatif. Subjek dalam penelitian ini  adalah lima orang perempuan dan lima orang laki-laki siswa VII. Peneliti menggunakan langkah-langkah menurut Soedjadi, (a) Membaca soal dengan cermat untuk menangkap makna tiap kalimat, (b) Memisahkan dan mengungkapkan apa yang diketahui dalam soal, apa yang diminta/ditanyakan dalam soal, operasi pengerjaan apa yang diperlukan, (c) Membuat model matematika dari soal, (d) Menyelesaikan model menurut aturan-aturan matematika, sehingga mendapatkan jawaban dari model tersebut, dan (e) Mengembalikan jawaban soal kepada jawaban asal. Hasil penelitian menunjukkan siswa perempuan mengalami kesulitan dalam memahami konsep pecahan (menyamakan penyebut), mengalami kesulitan dalam menentukan operasi pengerjaan seperti penjumlahan, pengurangan, perkalian dan pembagian serta tidak menuliskan kesimpulan terakhir sedangkan siswa laki-laki mengalami kesulitan dalam memahami soal sehingga kurang tepat dalam menyelesaikan hasil akhir serta menyamakan penyebut. Cara mengatasi faktor-faktor kesulitan dalam soal ceritaa matematika adalah memberikan intensitas latihan, menguatkan kembali konsep pecahan pada siswa perempuan dan meningkatkan komunikasi matematis siswa.Abstract:  This research is a qualitative descriptive study. The subjects in this study were five women and five male students VII. The researcher uses the steps according to Soedjadi, (a) Read the questions carefully to capture the meaning of each sentence, (b) Separate and reveal what is known in the question, what is asked / asked in the question, what work operation is needed, (c) Make a mathematical model of the problem, (d) Complete the model according to mathematical rules, so that the answer to the model is obtained, and (e) Return the answer to the original answer. The results showed that female students had difficulty understanding the concept of fractions (equating the denominator), had difficulty in determining work operations such as addition, subtraction, multiplication and division and did not write the final conclusions while male students had difficulty understanding the problem so that it was not correct the final result and equate the denominator. The way to overcome the difficulty factors in mathematical storytelling is to provide training intensity, reinforce the concept of fractions in female students and improve students' mathematical communication.

Abstract

Translation among multiple representations is one of the important abilities to be possessed by prospective mathematics teachers. The mathematics learning curriculum ranging from elementary to college level needs to emphasize the ability to translate mathematical ideas in a form of representation to different mathematical representation structures. Assessing of this ability is important because it can be used as a basis for developing other mathematical literacy skills. The purpose of this study is to describe the level of translation between mathematical representations of prospective mathematics teachers. A descriptive qualitative study was conducted to fourty prospective mathematics teachers in State Islamic University of Mataram. The selection of research subjects was carried out in a purposive sampling. Data were obtained from mathematical translational thinking task in the form of an assignment sheet consisting of 2 questions related to quadratic equations and task-based interviews. Data were analyzed using fixed comparison analysis, which is comparing incidents (phenomena) with the aim of classifying data. The study found five levels of translational ability between mathematical representations, which were named: level 0, level 1, level 2, level 3 and level 4. The characteristics of each level are built based on four mathematical translational thinking processes: unpacking the source of representations, coordinating initial stage, design the target representation and determine the equivalence between the source and target representations. The findings in this study could be used as a guide to develop an instrument to assess mathematical translation ability.

Abstract

Abstrak: Penelitian ini bertujuan untuk mengembangkan bahan ajar berupa worksheet Persamaan Differensial (PD) untuk kemandirian belajar mahasiswa. Worksheet yang dikembangkan terdiri dari beberapa subbab yakni (1) PD variable terpisah, (2) PD homogen, (3) PD eksak, dan (4) PD linier. Pengembangan produk ini menggunakan metode desain pengembangan 4-D yang dilakukan melalui 4 tahap yakni Define, Design, Develop, dan Diseminate. Subjek penelitan adalah mahasiswa dengan jumlah responden 7 mahasiswa untuk uji terbatas dan 40 mahasiswa untuk uji coba lapangan. Hasil pengembangkan yang diperoleh, nilai rata-rata persentase dari penilaian ahli adalah 75.33% yang berarti valid dan hasil uji coba terbatas diperoleh rata-rata persentase mahasiswa memberikan respon 84,29% yang berarti sangat baik serta uji coba lapangan diperoleh rata-rata persentase mahasiswa pada kelompok uji coba 1  maupun uji coba 2 memberikan respon 95.4% dan 92.9% yang berarti produk yang sedang dikembangkan berkategori sangat baik dan telah efektif, sedangkan tingkat kemandirian belajar mahasisiwa yang diperoleh dalam menggunakan worksheet persamaan difernsial adalah sedang. Sehingga ini menunjukkan bahwa worksheet yang dikembangkan dapat memberikan dampak yang positif terhadap kemandiran belajar mahasiswa. Abstract:  This research aims to develop the learning materials in the form of differential equation (PD) Worksheets for students ' independence. The worksheets are developed consisting of several subchapters, namely (1) PD variable separate, (2) PD homogeneous, (3) PD Exact, and (4) PD linear. The development of this product using 4-D development design method is done through 4 stages, namely Define, Design, Develop, and Disseminate. The research subject is a student with a total of 7 respondents for a limited test and 40 Students for field trials. The results of the development acquired, the average percentage value of the expert rating is 75.33% which means that valid and limited trial results are obtained average percentage of students give a response of 84.29% which means excellent and field trials The average percentage of students in the 1st and 2nd trial groups gave a response of 95.4% and 92.9% which means that the product under development was very good and effective, while the level of self-reliance learned the Obtained in the use of a worksheet is currently being. So this indicates that the developed worksheet can provide a positive impact on student learning.
