Abstract

The meaning of fractions with integer multiplication is something that is difficult to  understand by students. They tend to think that the product it produces a larger number, while the multiplication of fractions with integers, the result can be any number larger or smaller. This study is a research design that aims to develop a local instructional theory to support the students expand their understanding of the meaning of multiplication of fractions with integers. By applying the characteristics of realistic mathematics education (Realistic Mathematics Education), the researchers designed a  series of instructional activities related to daily life, such as Indonesia prepares dishes and equitable distribution. Participants of this study were Grade 5 students from an elementary school in Surabaya, along with a mathematics teacher of that class.  Some students of the class participated in the first cycle, in order to see how the design of the hypothetical learning trajectory (Hypothetical Learning Trajectory) is running. After going through several revisions, HLT is then implemented in all the other students in grade 5. The results showed that students prior knowledge affect their learning process. The fractions solve multiplication problems with whole numbers, some students convert the integers to fractions and then use a fraction by a fraction multiplication procedure. The learning process begins with students exploring the contextual situation of fair division, where students extend their understanding that the fraction associated with the division and multiplication. One indicator that the student has broadened his understanding is the more varied representation of the given problem.

Abstract

Fractions varied meanings is one of the causes of difficulties in learning fractions. These students  should be given greater opportunities to explore the meaning of fractions before they learn the relationship between fractions and operations on fractions. Although students can shading area represents a fraction, does not mean they really understand the meaning of fractions as a whole. With a realistic approach to mathematics, students are given the contextual issues of equitable distribution and measurements that involve fractions.

Abstract

This study is aimed to analyze probabilistic thinking of elementary school students based on math ability and gender differences. Descriptive explorative approach was used to describe in depth probabilistic thinking of boys with high, middle, low math ability and girls with high, middle, low math ability. The result showed that probabilistic thinking of boy with high math ability indicated multistructural because his thinking quantitative and proportional. While probabilistic thinking of boys with middle, low math ability and girls with high, middle, low math ability indicated unistructural because their thinking quantitative and non proportional. Beside that, boys’ thinking in solving probability tasks was more analytical and flexible than girls’ thinking. So, students with math ability difference, gave difference response in solving probability tasks. This result found new strategy in solving probability comparison task. This result could contribute to curriculum developer to introduce probability in elementary school level and teachers could use discussion method in teaching probability material.

Abstract

This research was conducted at 2 students of SMPK Anak Bangsa Surabaya grade VIII. Subjects were selected based on the basic of equal mathematics ability. Data was collected using provision of problem-solving and task-based interview. Data was analysed using data reduction steps, data presentation, and conclusions. Meanwhile, to obtain valid research data in this study, researchers used time triangulation. The results indicated that in the number 1 problem of identifying patterns, the subjects of men and women tend to have similarities in stating what is known and asked the question, but the male students are more specific to explain the magnitude of the difference between the first quantity Followed by increased differences in other quantities. Related activities determine the relationship between two quantities, male subjects and women subject tend to have similarities in how to determine the relationship between two quantities that is by trial and error using existing mathematical operations.It can be concluded that the functional way of thinking both subjects is relatively the same. Its just that the male subject is more specific in finding the difference between the two quantities and finding the correspondence relationship between the quantities

Abstract

Beliefs and pedagogical content knowledge (PCK) are two factors influencing teaching practice in the classroom. This research aims to describe the beliefs and PCK of the prospective mathematics teachers and the relationship between the two factors on the teaching practices in the mathematics classroom. Participant in this research includes a prospective teacher who has taken a micro teaching subject and has good communication skill. Data were collected through interview and video analysis on the teaching practice in the classroom. The data obtained were coded, simplified, presented, and triangulated for the credibility and concluded. The result of the research shows that the prospective teachers who hold a constructivist belief view mathematics as a dynamic knowledge which evolves and is regarded as the space of creation for humans. Their beliefs on the nature of mathematics support the belief in the teaching-learning process in mathematics classrooms. Furthermore, a good understanding of the prospective teachers have on the components of the PCK has been sufficient, which can be identified in every step of practical activities in the classroom. More elaboration on the relationship between the belief and PCK is presented in this research.

Abstract

Menulis suatu karya ilmiah merupakan salah satu upaya untuk meningkatkan profesionalisme guru. Akan tetapi, bagi seorang guru menulis adalah pekerjaan yang tidak mudah. Salah satu kendalanya adalah minimnya kemampuan guru untuk menganalisis data pada karya tulis ilmiah tersebut. Keadaan yang serupa terdapat pada perhimpunan guru dibidang matematika di Kediri. Oleh karena itu, solusi yang ditawarkan dalam kegiatan pengabdian kepada masyarakat (PKM) adalah mengadakan suatu pelatihan terkait analisis data dalam suatu karya tulis ilmiah. Dalam kegiatan pelatihan telah dilakukan sesi pemaparan materi baik secara teori maupun aplikasi pada software. Anggota yang hadir sebanyak 33 orang. Pada akhir kegiatan, telah dibentuk kelompok kecil yang terdiri dari 3 sampai dengan 4 peserta untuk menyelesaikan soal secara komprehensif. Hasil dari pelatihan ini akan dievaluasi baik dari sisi output maupun proses. Untuk kriteria output, yaitu ketuntasan pemahaman seluruh kelompok telah terpenuhi dimana lebih dari 75 persen tuntas. Artinya dari seluruh anggota peserta dalam kelompok, hanya sekira 25 % mendapatkan nilai 75 dari 100  dan sisanya mendapatkan nilai sempurna. Selain itu, ketuntasan pemahaman materi oleh setiap kelompok telah berhasil mencapai target yaitu diatas 75 persen ketuntasan. Hal ini dikarenakan ada 6 kelompok mendapatkan nilai sempurna (100) dan hanya 2 kelompok melakukan kesalahan minor dan hasil evaluasinya adalah 75. Sedangkan segi proses, respon yang diberikan oleh seluruh peserta juga sangat positif. Dengan demikian, dapat disimpulkan bahwa pelatihan telah berhasil sesuai dengan kriteria sisi output dan proses.

Abstract

Keyakinan (belief) terhadap matematika mempengaruhi bagaimana seseorang “menyambut” matematika. Keyakinan juga mempengaruhi prestasi belajar. Guru memegang peran penting dalam membangun keyakinan siswa terhadap matematika. Oleh karena itu perlu dikembangkan instrumen untuk mengukur keyakinan guru atau mahasiswa calon guru. Model pengembangan yang digunakan untuk mengembangkan angket menggunakan design research tipe development study. Tahap yang dilakukan yang terdiri dari tiga fase, yaitu: investigasi awal, fase prototype, dan fase assesmen Penelitian ini menggunakan teknik analisis deskriptif kualitatif dan kuantitatif. Hasil penelitian menunjukkan instrumen angket yang dikembangkan memenuhi kriteria valid dan reliabel berdasakan hasil analisis kuantitatif. Hasil analisis kualitatif juga menunjukkan terdapat tiga jenis keyakinan dalam pemecahan masalah dan pembelajaran yang dimiliki oleh mahasiswa calon guru matematika.
