Abstract

The purpose of this study was to confirm the factors that influence the sociomathematics norm. The method used in this research is the ex post facto. The subjects in this study were seventh-grade junior high school students in the city of Yogyakarta, Indonesia (264 students) taken by cluster random sampling. The instrument used was a sociomathematics norm observation sheet consisting of four factors are (1) the experience of mathematics, (2) the explanation of the mathematics, (3) mathematical differences, (4) mathematical communication. Data analysis using structural equation models with the Confirmatory Factors Analysis. The results showed that the modified path analysis obtained goodness of fit mostly in the fit category, so overall the sample covariance matrix is the same as the estimated covariance matrix.

Abstract

The purpose of this study was to improve the learning achievement of extroverted students on algebraic operations using the tutorial method. This type of research was a single subject with AB design, where A is the baseline condition, and B is an intervention condition. The research subjects were selected based on a purposive sampling technique with the help of the Keirsey Temperament Sorter (KTS) test in selecting extrovert subjects. Data collection techniques were using observation and test methods. Observation was used to collect data and record all behavior of extrovert subjects during the study. The tests in this study were the KTS and learning achievement tests. The KTS was used to determine subjects with an extroverted temperament while learning achievement tests are used to determine the ability of extrovert students to solve algebraic operation questions at the junior high school level. The results showed that the tutorial method had a positive effect on extrovert student learning achievement in algebraic operation material. This can be seen from the results of the analysis in conditions and between conditions which show that the intervention condition has a better tendency when compared to the baseline condition to the intervention. Besides that, the mean level obtained at the baseline is 50 and increases in the intervention condition with a mean level of 88.5.

Abstract

Mentally retarded is a mental disorder with an intelligence quotient (IQ) between 55-70, besides those mentally retarded children are only able to think concretely. For this reason, learning mathematics for mentally retarded students requires learning media that can bridge abstract mathematical material with the abilities of mentally retarded children who are only able to think concretely. The objective of this study was to improve the recognition of 1-20 numbers using number cards for students with mild mental retardation. The research used is single subject research method with basic design non reversal. Study subjects were selected based on a purposive sampling technique, as the researcher had to look for subjects with mild mental retardation. Data collection techniques use documentation to find out subjects with mild mental retardation characteristics, and tests to determine the subject's ability to recognize numbers 1-20. The results of this study indicate that the number card media can improve the ability of mild mentally retarded students to recognize numbers 1-20. This can be seen from the average in the baseline phase of 39 with a percentage of the ability to recognize numbers of 33.3%, and in the intervention phase of 74.44 with a percentage of the ability to recognize numbers of 88.89%.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kesalahan yang dilakukan siswa dalam menyelesaikan masalah segi empat pada fase konkret, dan fase transisi. Penelitian ini menggunakan penelitian kualitatif deskritptif dengan subjek penelitian sebanyak 4 subjek yang diambil berdasarkan purposive sampling. Teknik pengumpulan data menggunakan tes. Teknik analisis data menggunakan model yang dikembangkan oleh Miles dan Huberman yaitu reduksi data, penyajian data, dan menarik kesimpulan/verifikasi data. Kesalahan yang sering dilakukan siswa fase konkret yaitu siswa salah dalam menggambar bangun yang diceritakan soal, salah dalam menentukan rumus dan tidak menuliskan rencana penyelesaian, salah melakukan prosedur penyelesaian dan tidak menggunakan rumus secara semestinya, serta tidak melakukan pemeriksaan kembali jawaban. Kesalahan yang sering dilakukan siswa fase transisi yaitu siswa salah dalam menggambarkan bangun yang diceritakan dalam soal, salah dalam menuliskan rumus yang perlu digunakan, pada tahap melaksanakan rencana tidak terjadi kesalahan, serta tidak melakukan pemeriksaan kembali jawaban. This study aims to describe the mistakes made by students in solving rectangular problems in the concrete phase and the transition phase. This study uses descriptive qualitative research with four research subjects taken based on purposive sampling. Data collection techniques using the test. Data analysis techniques using a model developed by Miles and Huberman, namely data reduction, data presentation, and concluding/verification of data. Students often made mistakes. In the concrete phase, students making drawings that are told about problems.  Errors in determining formulas and not writing completion plans, error when doing completion procedures and not using formulas properly, and not re-checking answers. In the transition phase, students who are wrong in describing the shapes told in the problem. Errors in writing the formula that needs to be used, at the stage of carrying out the plan there is no error, and not re-checking the answers.
