<![CDATA[The purpose of this research is to use science, technology, engineering and mathematics (STEM) methods for effective and practical ongoing assessment, which is based on multiple representations and combined with the 21st learning magnetic field ability of Indonesian Lampung Bandar Lampung High School students. This ongoing assessment development adapted the Borg and Gall development model, which was grouped into four stages, such us: preliminary research stage, planning and development stage, the field test stage, and the dissemination stage.
