Abstrak Penelitian ini bertujuan untuk menggambarkan kemampuan pemecahan masalah siswa pada materi keliling dan luas segitiga melalui metode problem solving. Penelitian dilaksanakan pada SMPN 1 Batukliang Utara pada tahun pelajaran 2017/2018. Subjek yang terlibat dalam penelitian ini adalah siswa kelas VII sebanyak 23 orang siswa. Data dikumpulkan menggunakan dua LKS yang telah dikerjakan oleh siswa secara berkelompok dan kemudian dikonfirmasi melalui wawancara yang dilakukan oleh peneliti terhadap beberapa orang siswa perwakilan kelompok. Penelitian ini menggunakan tiga tahapan dalam teknik menganalisis datanya, yaitu tahap reduksi data, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa dari dua LKS yang dikerjakan siswa secara berkelompok, setiap kelompok berusaha untuk memahami masalah dengan membaca soal tersebut tanpa bersuara dan mengubah informasi dalam soal ke dalam bahasa yang sering digunakan oleh siswa. Setiap kelompok mampu menuliskan apa yang diketahui dan apa yang di tanyakan pada soal. Saat menetapkan jawaban sementara, setiap kelompok hanya mampu menyelesaikan masalah dengan satu cara yang hanya dipahami oleh masing-masing kelompok yaitu dengan menggunakan rumus keliling dan luas segitiga. Pada langkah pemeriksaan kembali dan penarikan kesimpulan, masih terdapat beberapa kelompok yang hanya melihat hasil atau jawaban yang didapatkan tanpa membuktikan kembali apakah jawaban yang didapatkan sudah benar atau tidak. Kata Kunci: kemampuan siswa; pemecahan masalah; keliling dan luas segitiga Students’ Problem Solving Ability in Perimeter and Area of Triangle Abstract This study aims to describe students' problem-solving abilities in the perimeter and the area of the triangle through problem solving methods. The study was carried out at North Batukliang 1 Junior High School in the 2017/2018 school year. The subjects involved in this study were 23 grade VII students. Data was collected using two worksheets that had been done by students in groups and then confirmed through interviews conducted by researchers against several students representing the group. This study used three stages in the technique of analysing the data, namely the stages of data reduction, data presentation and conclusion drawing. The results showed that of the two worksheets that students worked in groups, each group tried to understand the problem by reading the questions without speaking and changing the information in the questions into the language that was often used by students. Each group is able to write down what is known and what is asked about the question. When setting a temporary answer, each group is only able to solve the problem in one way that is only understood by each group, using the perimeter and the area formula of the triangle. In the re-examination steps and conclusions, there are only several groups that look back at the results/ answers have been obtained without proving whether the answers obtained are correct or not. Keywords: students’ ability; problem solving; perimeter and area of triangle

Abstract This study aims to develop multimedia teaching materials based on PBL using 3D Professional Pageflip on geometry material, and determine the effectiveness of PBL-based multimedia teaching materials using 3D Professional Pageflip on geometry material. This research is a development research with the research process using the ADDIE model which consists of 5 stages, namely analysis, design, development, implementation, and evaluation.Validation was carried out by material experts and media experts with individual test subjects, namely 2 mathematics teachers, small group trial subjects consisted of 6 students, and large group trials namely students of XIPA2 class of SMAN 5 Jambi City. The instruments used in this study were questionnaires for evaluating material experts and media experts, teacher and student responses questionnaires, student perception questionnaires and student learning outcomes tests.From the results of the post-test analysis conducted at the end of the learning activities obtained 90.32% of the students achieved the minimum completeness criteria, the results of the analysis of the student perception questionnaire showed the category of "very positive" besides based on observations of students' attitudes during the learning process positive and high enthusiasm in participating in learning activities. This means that multimedia teaching materials that are made effective are used for the learning process. Keywords: multimedia teaching materials, problem based learning, 3d pageflip professional, geometry

Abstract The ability to understand concepts is very important and becomes the basis for supporting the solving of mathematical problems. The connection between one concept and another concept and one topic with another topic is a characteristic of learning mathematics. The relationship requires that each student must have the ability to understand the concepts well, but it cannot be denied that the ability to understand mathematical concepts is still low, as happened to theLangke Rembong 4Junior High School students. Learning innovation needs to be done to achieve a good understanding of concepts. This study aims to compare the understanding ability of mathematical concepts of students who follow a guided inquiry learning model with students who take direct learning. The research design uses Posttest only control group design. The population is all eighth grade students of Langke Rembong 4 Junior High School, totalling230 students. Sampling is done by random sampling with equality test between classes.It is then obtained class VIII A as the experimental class and class VIII C as the control class. Data collection uses tests in the form of description questions. Data analysis uses t-test with normality test and homogeneity test for the assumptions. The results show that the students who follow the guided inquiry learning have higher understanding of mathematical concepts than those who are taught with direct learning model. Keywords: inquiry, understanding of mathematical concepts

Abstract This study aims to determine the effect of the Model-Eliciting Activities (MEAs) approach towards the students’ mathematical communication skills. This research is a quasi-experimental study by the nonequivalent posttest-only control group design. This research population was the eighth-grade students in SMP Negeri 2 Sungai Penuh that consisted of seven groups. The sample in this study consisted of two groups, namely VIII C as an experimental group and VIII D as a control group selected by cluster random sampling technique. In the experimental group, the MEAs approach was done while the control group was done with conventional learning. The research instrument used to measure students’ mathematical communication skills was a subjective test. The data were analyzed using the independent t-test. The results of data analysis showed that there is an effect of MEAs approach towards the students’ mathematical communication skills. Keywords: Model-Eliciting Activities (MEAs) Approach, Mathematical Communication Skills

This research aims to determine the effect of initial ability and self confidence together on mathematical communication ability, the effect of initial ability on mathematical communication ability, and the effect of self confidence on mathematical communication ability. This study uses a survey method, with multiple regression analysis techniques. Samples were taken using a random sampling technique. The data processing carried out results in a multiple regression equation Y = -2.365 + 0.110 X1 + 0.283 X2, the coefficient of determination (R Square) = 0.22, FCount (0.787) smaller than FTable (3.126), and tCount smaller than tTable . The conclusion of this study is the initial ability and self confidence together do not have a significant effect on mathematical communication ability, the initial ability does not have a significant effect on mathematical communication ability, and self confidence has no significant effect on mathematical communication ability. This study needs to be studied further because only 22% of the value of mathematical communication ability can be explained by using the initial ability value and self confidence, while 78% must be explained by other causative factors. Keywords: Initial Ability, Self Confidence, Mathematical Communication Ability
