Abstract

This study aimed to design a hypothetical learning trajectory for a two-dimensional figure area (quadrilateral and triangle) using the geometric shape of traditional food, tempe mendoan as a learning context. This research was qualitative research with data collection methods using literature studies, interviews, and documentation. The subjects in this study were seventh-grade junior high school students in SMP IT Nurul Fikri Bogor. The results of this study are in the form of a hypothetical learning trajectory design in learning the two-dimensional figure area through exploration of Banyumas food tempe mendoan, students measure each side of the rectangle from the shape of tempe mendoan, students divide the rectangle into square units as many as the results of each measurement side, students counts the number of unit squares that cover the rectangular area, the student finds the formula for the area of ​​a square and a rectangle. Next, students divide one rectangle into two right triangles of equal size, students find the formula for the area of ​​a triangle. Students attach the triangles to the provided two-dimensional figure shapes, students record the number of right triangles needed to cover each shape and find these relationships so that students can find area formulas for other shapes such as parallelograms, trapezoids, and rhombuses.

Abstract

The purpose of this study is to determine the effect of the TGT (Teams Games Tournament) learning model on statistics material for class VII junior high school on mathematical problem solving abilities. This research was a quantitative research using Quasi Experimental Design. The sampling technique in this study used purposive sampling. Class VII D, consisted of 24 students as the experimental class and class VII C consisted 24 students as the control class. The instruments used in this research were Pretest-Posttest with 3 questions. The data analysis techniques used in processing the data were analysis prerequisite tests (normality test and homogeneity test), hypothesis testing, and the N-Gain test. Based on the results of calculations that have been carried out, the posttest average value for the experimental class was 92, while the posttest average value for the control class was 85. In addition, based on the data obtained from the results of the hypothesis testing, it results that the  value is 0.000 then Ho  is rejected and Ha is accepted. This is in line with the average N-Gain value in the experimental class resulting in 0.82 high criteria, while the average N-Gain value in the control class produces 0.66 medium criteria. So it can be concluded that there is an influence of the TGT (Teams Games Tournament) learning model on students' mathematical problem solving abilities.

Abstract

Menurut observasi penulis dilapangan sewaktu guru mengajar di dalam kelas ada beberapa siswa yang mendapat kesukaran dalam memahami mata pelajaran matematika. Dimana siswa akhirnya menjadi jenuh, menganggap matematika pelajaran yang susah, sehingga siswa menilai bahwa matematika merupakan pelajaran yang membosankan. Untuk mengurangi hal tersebut dibutuhkan media pembelajaran terbaru dan menarik untuk merangsang daya kreatifitas para siswa, diantaranya menggunakan media animasi audiovisual  Powtoon. Metode yang digunakan adalah  RnD (Pengembangan). Hasil diperoleh bahwa media audiovisual PowToon memenuhi nilai kelayakan yang digunakan sebagai media pembelajaran. Dari hasil validasi materi menunjukkan kategori valid dengan memperoleh nilai 3,53. Untuk aspek media memperoleh nilai 3,28 dengan kategori valid, untuk aspek tampilan program memperoleh  nilai 3,5 dengan kategori valid, dan untuk aspek kualitas teknis dan keefektifan program memperoleh nilai 3,5 dengan kategori valid.

Abstract

This study is a preliminary study that aims to describe the algebraic thinking process of students who teach linear programming. This study is a qualitative descriptive study. Subjects are grouped into three categories, namely high, medium, and low mathematical abilities. Data were obtained based on test results that were analyzed based on students' algebraic thinking processes. The results of this study indicate that students with high and medium abilities carry out algebraic thinking ability activities well. Starting from generalization, abstraction, modeling, dynamic thinking, and analytical thinking, as well as organization. The advantages of students with high mathematical abilities are being able to provide other strategies in solving the problems given. Meanwhile, students with low mathematical abilities are still weak in dynamic, analytical, and organizational thinking activities. One of the contributing factors is the lack of students' ability to represent what is known into mathematical models (inequalities), the use of mathematical symbols, and algebraic operations. The difficulties experienced by students affect students in solving linear programming problems related to the optimum solution material. Keywords: thinking process, algebraic thinking, linear programming
