Abstract
This research aimed to produce a learning trajectory on prism volume material in problembased learning. The type of research used is design research with three stages: (1) preparing for the experiment, (2) design experiment, and (3) retrospective analysis. The research subjects were students of class VII in 2 Wonogiri junior high schools. The trial of hypothetical Learning Trajectory (HLT) for cycle 1 or so called pilot experiment involved 6 students of class VII E and trial of HLT for cycle 2 or so called teaching experiment involved 32 students of class VII G. The instruments for data collection were observation sheet, interview protocol, and learning video recording. The prism volume learning trajectory started from definition of the prism, determining the elements of prism, grouping examples and non-examples of prism, and finding the formula for the volume of prism. The research obtained that the learning trajectory can contribute to assist students in finding and developing an understanding of the concept of prism
volume formula.
