Visual Media in Team Accelerated Instruction to Improve Mathematical Problem-Solving Skill

The ability to solve mathematical problems is one of the abilities that must be possessed by every student. To improve this ability, a learning model is needed that can construct knowledge for each student, one of the alternative constructivist learning including Team Accelerated Instruction. In Mathematics learning, one of the obstacles that is often experienced by teachers and students include the concept of mathematics that is abstract, so that students have difficulty understanding the concept. To bridge the mathematical concept that is an abstraction, a media is needed that can concretize the abstract mathematical concepts. This article aims to construct Team Accelerated instruction using visual media to improve mathematical problem solving skills. The results of the instruction can be concluded that by using visual media on Team Accelerated Instruction learning, the skills of mathematical problem solving is thought to be more.
