Mathematical Word Problem Solving in Students Elementary School: is Schema-Based Instruction (SBI) or Cognitive Strategy Instruction (CSI) Used?

The type of problem solving of mathematical words is a mathematical domain that is quite difficult for learners in primary school. This is due to learners are not only adept to the ability of numbers and counting, however, as well as related to the understanding of the text on the word problem. Schema based instruction and cognitive strategy instruction is an explicit instructional approach applied to solving word problems, especially for learners who have difficulty in the area. Both of these instructional approaches are discussed in this article along with examples of problem solving of mathematical words which are the results of previous research by experts.   Keywords: Mathematical word problem solving, schema based instruction, cognitive strategy instructio
