Abstract

This article is a best practice implemented by applying the learning model of SPS-Bansho (Structured Problem Solving using Bansho) at SMPN 18 Tangerang. This best practice has succeeded in increasing students’ mathematics learning activities during the learning process. The observation sheet was used to observe the students’ mathematics learning activities. All indicators of students’ mathematics learning activities were observed during the learning process. Students were challenged more to ask questions during a group or class discussions. They were able to respond to their friends' opinions well, participate in groups, and help friends in completing assignments. Students presented their work in front of the class, and they could summarize the material they have learned.

Abstract

To help students in solving the linear equations in one variable, teacher can use a learning media such as algebra tiles. Algebra tiles are square and rectangle-shaped tiles that represent numbers and variables. Algebra tiles consist of three different-size pieces. The smallest tile is square shape and represents ± 1, the other tile is rectangular shape and represents ± x and the largest tile is large square shape that represents ± x2. The pieces are usually colour-coded so that one colour represents positive values and another color represents negative values. This research is a best practice that was conducted at class VII.7 SMPN 18 Tangerang.  The aim of this research is to describe how the algebra tiles supports students’ understanding in solving linear equations in one variable. The competence achievement indicators are: modelling algebraic expressions using algebra tiles; solving linear equations in one variable using algebra tiles; solving linear equations in one variable without use algebra tiles. Data collection through photos, videos, worksheet and students’ work. Students did reducing and balancing ways to find the simple form of algebra tiles. The purpose of reducing or balancing of both sides of linear equations in one variable is to get how many square tiles that equals to one rectangular tile. Algebra tiles made students to be easier in solving linear equations in one variable. Students were very happy to learn mathematics using algebra tiles. The algebra tiles supports students’ understanding in solving linear equations in one variable.
