VALIDATION OF SCIENTIFIC LITERACY ASSESSMENT INSTRUMENT FOR HIGH SCHOOL GRADUATES IN TRAFFIC APPLIED PHYSICS CONTEXT

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT:

We present the validation procedure of an instrument to verify aspects of Scientific Literacy for High School graduates. The questionnaire was divided into questions about concepts of applied Physics in traffic situations and on the profile characters of the physics classes attended by the graduates during High School. Initially, it counts 64 items, that were assessed for their content by teachers in the area and later, through statistical tests, the quantitative results for validation and reliability were estimated. Finally, we remove 19 items and a valid and reliable instrument was obtained with 25 items on traffic applied Physics and 20 items on the Physics Education profile, for use in scientific literacy assessment.
