Abstract

This Classroom Action Research was aims to improve students' mathematical learning completeness through the instructional system development procedures learning model (PPSI). The research was implemented in Baitul Quran Junior High School in Langsa during the even semester of 2019-2020 Academic Year. The population of this study was all students of grade 8th at Baitul Quran Junior High School which amount 7 (seven) students, where the whole students were included into the sample of research. The direct sampling technique was used in this study related to the small number of population (<10). The data were collected by using pre-test and post-test method for the main and documentation as complementary. The data analysis shows that only two students on the pre-test or initial test which obtained more than 70 (Minimum completeness criteria) or around 28.57%. The post-test shows that students' mathematical learning completeness after the implementation of PPSI were increase to 5 students who got a value of more than 70 (Minimum completeness criteria) or around 85.71%. So that from the analysis of pre-test and post-test data it can be concluded that the use of instructional system development procedure learning model (PPSI) in Baitul Quran Junior High School can improve the students’ mathematical skill.

Abstract

Masalah pokok dalam penelitian ini adalah bagaimana pemahaman konsep siswa smp berdasarkan persepsi matematika. Tijuan dari penelitian ini adalah untuk mengetahui pemahaman konsep siswa smp berdasarkan persepsi matematika. Jenis penelitian ini adalah penelitian deskriptif kualitatif dengan teknik pengumpulan data dilakukan dengan member instrumen persepsi, tugas pemecahan masalah (TPM) kepada siswa dan pedoman wawancara. Setelah mengetahui persepsi masing-masing pada siswa tersebut, yaitu persepsi positif dan persepsi negative. Masing-masing siswa mengerjakan tugas pemecahan masalah (TPM) kemudian langsung dilakukan wawancara mengenai hasil pekerjaan siswa tersebut. Dalam penelitian ini, dipilih dua siswa laki-laki dengan persepsi yang berbeda.Penilaian pemahaman konsep siswa didasarkan pada tiga indikator yaitu penerjemahan (translation), penafsiran (interpretation), dan ekstrapolasi (extrapolation). Hasil penelitian ini menunjukan bahwa pemahaman konsep siswa tipe dua persepsi positif dan negatif memiliki tingkat kemampuan yang sama., tetapi mereka mengerjakan TPM tersebut sedikit berbeda sesuai dengan daya tangkap masing-masing siswa tersebut dengan durasi waktu yang berbeda. Berdasarkan hasil penelitian ini diharapkan guru sebaiknya juga meperhatikan persepsi siswa agar lebih cepat tangkap informasi dan pelajaran.

Abstract

The purpose of this study is to examine: Improvement of mathematical communication skills of students who obtain Gerlach and Ely learning is better than mathematical communication skills of students who obtain conventional learning, The relationship between students' initial mathematical abilities with Gerlach and Ely learning towards communication skills mathematical, but the relationship between students' mathematical communication skills with student mathematics learning outcomes. This research is a semi-experimental research. The population of this study were all IT students Baitul Quran Langsa, amounting to 22 students where 15 students were in class VII and 7 students were in class VIII. Then the two classes are given different treatment of the learning model. The experimental class was treated with Gerlach and Ely learning and control classes with conventional learning. The instrument used consisted of: a test of mathematical communication skills. The instrument was stated to have fulfilled the content validity requirements, and the reliability coefficient was 0.87. Data analysis was performed with the t-test statistical test, bivariate correlation test and 2-way anova test. Based on the analysis results obtained by the results of the study are: an increase in mathematical communication skills of students who get Gerlach and Ely learning better than students who obtain conventional learning, there is no interaction between learning with students 'initial ability to increase students' mathematical communication skills, there is a positive relationship between students' mathematical communication skills and student mathematics learning outcomes. Descriptively the answers to the problem formulation were also examined, namely: the process of solving students' answers whose learning with Gerlach and Ely learning was neater and more complete based on indicators of mathematical communication skills compared to students who used conventional learning. Based on the results of the study, the researchers suggest: Gerlach and Elypada learning of mathematics to improve students' mathematical communication skills can be used as an alternative to applying varied and innovative mathematics learning.

Abstract

This study aims to examine the increase in motivation, perception, and preferences for mathematics education through ancient methods or techniques. In this study, the approach used is quantitative by using non-parametric statistical tests, namely: Hypothesis testing on signs, hypothesis testing through the Wilcoxon Signed level, and hypothesis testing for changes. The conclusion from this research is that the experiment is in the form of giving treatment or stimulating mathematics learning through ancient methods or techniques in the form of: Addition of Many Numbers with the Ladder of Wisdom, Easy Subtraction with the Nine Yin Yang Technique, Easy Multiplication with Napier's Bones, and Easy Division using the Chunking Method (Chunk It). ): 1) able to increase motivation in mathematics learning based on hypothesis testing on signs, 2) able to change the perception that learning mathematics is easy and fun based on testing the Hypothesis through the Wilcoxon Marked Level, and 3) able to change preferences to become students who are diligent in learning mathematics based on testing hypotheses for change.
