The impact of the Covid-19 Pandemic changed the world of education, especially in the implementation of Teaching and Learning Activities. In the learning process, for example the teacher no longer has to face to face with students because it can be done online. This research aims to develop an online learning device based on PDEODE (Predict - Discuss I -Explain I - Observe - Discuss II - Explain II). The type of research used is Research and Development (R&amp;D) using the 4-D model (Define, Design, Development, Desiminate). However, this research only reached the develop stage. This online learning device was validated by 6 expert validators, which included 2 material expert validators, 2 media expert validators and 2 learning expert validators. This PDEODE-based online learning devices has already been tested on its product design for teachers and grade X students at SMKN 53 Jakarta. The result shows that the PDEODE based online learning devices is “very good” because it has been through the validation test stage and trial phase with a percentage of achievement as much as 63.77% according to material experts, 89.94% according to media experts and 85% according to learning experts. The results of trials by teachers and participants students show the percentage of teacher responses as much as 94% and overall can be a percentage of 83.18%. Based on the analysis of data that has been collected can be concluded that PDEODE-based online learning devices on the Doppler Effect material are very good/feasible to be developed and used in this Covid-19 Pandemic Era.
