The transformation of two-tier test into four-tier test on Newton’s laws concepts

This research is based on other forms of diagnostic tests in the format of two-tier test about the concept of Newton’s Laws that the development still not yet well. Therefore, must be done a research to transform two-tier test into the four-tier test that refers to Kaltakci criteria. To achieve the purpose, the researchers used the 4D model (Defining, Designing, Developing, and Disseminating) as a method of research. The participants are 25 students at one of the senior high schools in Bandung. The result is the development of two-tier test format intothe four-tier test formatabout Newton’s Laws concept. At the disseminating, there are obtained the category of students who scientific knowledge, misconceptions, and errors of the Newton’s Laws concepts. The research will be the reference or preliminary research to conduct further research.
