Analogical reasoning is very important for students because it is a major process in scientific discovery and problem solving, as well as in category making and decision making. Therefore, This study aims to develop a GeoGebra dynamic worksheets to enhance students^ analogical reasoning abilities. Using of Dynamic GeoGebra Worksheets or Dynamic Activities because students can interact with the worksheets. Students are expected to carry out the analogical reasoning process through the developed worksheets. This study used Design Didactical Research (DDR). The development of the worksheets is based on the learning obstacles faced by students when carrying out the analogical reasoning process.
