Student's mathematical problem solving ability has optimal yet, this is due to school learning fail to get students used to work on problem solving PISA questions model. The purpose of this research is to produce mathematics learning device based on guided discovery of PISA model orientation in order to improve student's problem solving ability. This is a development research. Development model of this research is Plomp model which consists of three phases, namely, preliminary research, development or prototyping phase, and assessment phase. The results of data analysis on preliminary research are: 1) Teacher has yet to be able to develop the learning device to improve students' mathematical ability. 2) Learning resources used by the students are optimal yet to be able to draw student's interest to learn. 3) Students are expecting for the attractive worksheet display and small number of the questions. 4) Students are expecting worksheet to discuss more on the use of mathematics in the society real life and problems related with their personal activities. 5) Students who are living in the remote area tend to be less motivated and less willing the learning process. 6) Students prefer group learning to individual learning. © 2020 IOP Publishing Ltd.
