Abstract

AbstrakPenelitian ini bertujuan untuk mendeskripsikan proses penalaran aljabar siswa sebagai hasil dari pelaksanaan pembelajaran problem based learning (PBL) dalam pembelajaran matematika.  Jenis penelitian ini adalah menggunakan metode kualitatif dengan subjek penelitian 3 orang siswa yang diambil dari 27 siswa kelas VII B SMP N  2 Ambarawa. Data hasil penelitian dianalisis dengan mendeskripsikan kemampuan penalaran aljabar siswa sesuai dengan indikator dan tingkat level penalaran siswa pada pembelajaran matematika. Teknik pengumpulan data yang dilakukan dengan observasi, tes dan dokumentasi. Hasil penelitian ini menunjukkan bahwa pembelajaran matematika menggunakan model (PBL) tingkat kemampuan penalaran aljabar siswa pada kemampuan tinggi mampu mengenal pola, mencari pola, dan menggeneralisasikan pola. Siswa kemampuan sedang tidak dapat menggeneralisasikan pola tetapi mampu mengenal dan mencari pola. Siswa kemampuan rendah hanya mampu mengenal pola.AbstractThis research aims to describe the process of students’ algebraic reasoning as result the implementation of problem based learning (PBL) in mathematics learning. This type of research is using qualitative methods with 3 students' research subjects drawn from 27 students of class VII B junior high school N 2 Ambarawa. The data was analyzed by describing students' algebraic reasoning skills according to indicators and the level of reasoning of students in math learning. Data collection techniques are carried out with observation, test and documentation. The results of this study showed that mathematical learning using models (PBL) levels of algebraic reasoning ability students at high ability are able to recognize patterns, look for patterns, and generalize patterns. Students of moderate ability are unable to generalize patterns but are able to recognize and search for patterns. Low-ability students are only able to recognize patterns.

Abstract

Education is something that is very important to shape the quality of human resources so that they are ready to face the challenges of the industrial revolution 4.0 era so that many factors influence the success of education in preparing creative, innovative and highly competitive human resources, one of which is the educational curriculum. The curriculum in Indonesia refers to the 2013 curriculum using the HOTS assessment system which can help improve critical, logical, analytical and creative thinking skills in finding new problems. The aim of this research is to analyze the items on the HOTS assessment instrument for junior high school mathematics that are valid, reliable, have an acceptable level of difficulty and differentiating power. The method used in this research is qualitative research, namely analyzing triangle and quadrilateral questions in class 7 of junior high school as many as 31 students. The technique of collecting data is by means of a written test and the instrument used is a description of 4 questions. The research results show that the calculated r_value in the validity test is from 0.666 to 0.918 if the r_table category is 31 people, namely 0.666, then the validity test of the questions is valid. Reliability has a value of 1.3324 with r_table having a value of 1. The level of difficulty is easy because the value is from 0.8 to 0.914. Meanwhile, the difference in power has a score from 0.158 to 0.389 with sufficient and less categories. Because all of the instruments meet the question items at the level of validity, reliability, level of difficulty and differential power, these question items can be used.

Abstract

Mathematics is a science that deals with studying abstract forms, so it requires teaching aids to make it clearer and more real. Developments in science and technology have occurred, one of which is Android-based learning media. The aim of this research is to develop mathematics teaching materials assisted by the Math City Map application for class VII material at SMP Negeri 2 Ambarawa. Furthermore, after carrying out development, validity and feasibility trials were carried out by media experts, material experts and learning practitioners and tested on students. This research uses the Research and Development (R&D) method in its development using the ADDIE model which includes analysis, design, development, implementation and evaluation stages. The learning products are mathematics teaching materials (LKPD), math city map applications, and lesson plans which are prepared based on learning on plane material. Mathematics teaching materials (LKPD), the Math City Map application and lesson plans are arranged based on indicators and the first expert gets scores respectively, namely 110, 180 and 96. The second expert gets scores respectively 100, 162 and 87. and the third expert 103, 163, and 88. The three scores obtained were in the valid category so that mathematics teaching materials assisted by the Math City Map application in class VII middle school flat figures material were suitable for use.
