This research aims to develop a learning devices based on guided discovery methods that have valid, practical, and effective characteristics in order to improve the problem solving ability of grade VII SMP/MTs. The learning devices developed include lesson plan and student worksheet. The subject of this research was students of grade VII MTsN 1 Kerinci. The type of this research is development research using a PLOMP model that has three phases, namely, preliminary research, development or prototyping and assessment. The preliminary phase of research consists of needs analysis, curriculum analysis, student analysis, and concept analysis. Based on the results of preliminary research obtained the information that student problem-solving ability are not optimal, one of the factors that cause this is the unavailability of learning devices that can facilitate Students to improve their problem solving abilities. In the development or prototyping phase of the activities conducted is designing products such as lesson plan and student based Discovery guided, which then conducted a formative evaluation to determine the validity and practicality of the product. At the last stage, the assessment phase is conducted assessment of practicality test and effectiveness test. © 2020 Published under licence by IOP Publishing Ltd.
