Abstract: Problem solving and communication are mathematical process skills that are essential to learning mathematics. They are also important skill in daily life. However, the results of national and international assessments reflect that Thai students lack these mathematical skills. This research aims to 1) study learning implemantation using a mathematical argumentation model to promote mathematical problem solving abilities and mathematical communication abilities in subject area of the volume and capacity of rectangular shapes, and to 2) study the mathematical problem solving abilities and mathematical communication abilities of students after learning activities using a mathematical argument model in subject area of the volume and capacity of rectangular shapes. This research used a classroom action research model. The target group was the grade 5 students, totaling 15 persons. The research instruments were 1) lesson plans, 2) worksheets, 3) test of mathematical problem solving and mathematical communication and 4) observation form. Data were analyzed by content analysis and check for the trustworthiness of the data by methodological triangulation. The research findings were 1) learning implementation using using a mathematical argumentation model that promotes mathematical problem solving abilities and mathematical communication abilities should be highlighted, in preparing of basic knowledge to students in a variety of ways, consistently using provoking questions with students and student participation. In addition, the problem situations should be challenged and various solutions to the problems. 2) Most students had increasingly developed mathematical problem solving abilities and mathematical communication abilities after learning through a mathematical argumentation model in subject area of the volume and capacity of rectangular shapes.
