The world's tendency to develop competence in secondary education and the need to reform secondary education in Vietnam today aim to reach UNESCO's four pillars of learning in the 21st century learning to know, learning to do, learning to be, and learning to live together. This article aims to create opportunities for students to form and develop their mathematical representation competencies through teaching Mathematics in junior high schools in Vietnam. By surveying 1390 students in 15 secondary schools about the actual situation of learning mathematical representations, to analyze, compare and propose solutions to improve mathematical representation competence for students. The results showed many opportunities for students to observe and compare, help students understand and use different mathematical representations when expressing similar relationships, and flexibility in mathematical operations in the learning process.

Average Percentage

This study aims to determine the development of mathematical representation skills of junior high school students (SMP) based on mathematical exam results data in 2014-2016. The research data was obtained from responses of students' answers consisting of 1,535 students in 2014 and 2,000 students in 2015 and 2016 classified based on indicators of mathematical representation ability. In addition, the classification of student response data is also by gender and type of school. This research is a descriptive research using tables and graphs to describe data analysis of the development of the ability of mathematical representation in each year. The results show that the average percentage of mathematical representation ability of junior high school students in creating and using representations to organize, record and communicate mathematical ideas decrease every year. In indicators uses representation to model and interpret the physical, social, and mathematical phenomena increase in 2014 to 2015 but decrease in 2016. In general, the average percentage of mathematical representation ability of male students is higher than female.

Analytical Geometry

Generally, the experimental technique of teaching mathematics has been relegated to the elementary and junior high school levels. However, this technique can he used advantageously in helping high school students perceive spatial relationships. The following experiment on cycloids was performed by a group of high school students studying analytical geometry. The purpose of the experiment was to help the students visualize the locus of a moving point—something that students have found difficult to do.

The City

This study aims to analyze and examine in depth about the ability of mathematical representation that influenced the active learning of junior high school students. The method in this research using correlational method with quantitative approach. The population in this study is all junior high school students in the city of Bandung with a sample of students selected class IX Junior High School in the city of Bandung amounted to 22 students. Instrument in this research is a test of Reverentasi mathematical ability as much as 6 item and student activity scale as much as 21 scale statement. The results of this study concluded that the ability of mathematical representation of junior high school students is positively influenced by learning activeness of 93%, while 7% is influenced by other factors outside of student learning activity.
