Students' mathematical communication skills are still low and need to be improved. Learning tools do not support the student learning process. This study aims to produce a learning trajectory for lst-order differential equations. This type of research is a Plomp type research design consisting of three phases: (1) preliminary phase (preliminary research phase), (2) prototyping phase (prototype development phase), and (3) assessment phase (assessment phase). This section reports the preliminary phase. The conclusion is that the device has not facilitated students to make their own strategies to find concepts. Students need teaching materials in the form of worksheets that contain contextual problems that are close to students and facilitate student learning flow in rediscovering the theoretical concept of Ordinary Differential Equations (ODE). © Published under licence by IOP Publishing Ltd.
