Meningkatkan Hasil Belajar Siswa dengan Model Snowball Throwing pada Pokok Bahasan Penyelesaian Pertidaksamaan Kuadrat

[Title: Improving Student Learning Outcomes with the Snowball Throwing Model in the Subject of Solving Inequality Squared] The problem raised in this study is the low student learning outcomes. The research objectives are to improve student learning outcomes. The researcher wants to solve this problem by applying the snowball throwing model on the subject of solving the inequality squared in class X IPA 1 Manda Elu Private High School. This type of research is classroom action research (CAR) with two planned cycles. For each cycle consists of five stages, namely planning, implementing actions, observing, evaluating, and reflecting. The research subjects were teachers (researchers) and students of class X IPA 1 at Manda Elu Private High School. Collecting data in this study using written tests and observation sheets. The research data were analyzed descriptively-quantitative for test result data and descriptive-qualitative data for observation. The results showed that student learning outcomes improved, this can be seen from the percentage of classical completeness that is the first cycle of 54.3% increased in the second cycle 80%. From the results of the first cycle and second cycle increased, which means that more and more students received grades ≥65 (KKM). Based on the results of the study it can be concluded that the application of the snowball throwing model on the subject of solving the inequality squared can improve learning outcomes of class X students of Manda Elu Private High School

Pemahaman Siswa Tentang Equal Sign dalam Menyelesaikan Tugas Matematika

[Title: The Students' Understanding of Equal Sign in Completing Mathematics Tasks]. This study aims to describe the student's understanding of the equal sign to solve mathematical tasks. This study was included in the qualitative descriptive study. In this study, the data collected is the data of student's work and verbal data (the interview). The subjects were six students of 7th class of MTs Attariqie Malang 2014/2015 (Junior High School), with details of two high-ability students, two students capable of being, and two low-ability students. Students' understanding of the equal sign examined further by providing tests and interviews in six research subjects. Interviews were conducted individually after the students work on the problems individually. The mathematical task load arithmetic and algebra problems. Based on the results of the study, all subjects were able to understand the equal sign as operational and the equal sign as a substitution. For equal sign as the basic relational, only high-ability students were able to understand it. Understanding of medium and low student capable entrenched in the operational pattern that is an equal sign as operational cause confusion to understanding equal sign as the basic relational, eg, 14+11=25+8 where students only pay attention to the results of operations that 14 plus 11 is 25 without notice relation of the addition of 8
