The aim of this research is to identify factors affecting girls negative attitudes towards physics and suggests pedagogical approaches that can help secondary physics teachers to engage girls in physics. In this study we used survey method and standardized questionnaire and try to find factors that affect girls negative attitude towards physics study. The sample consists of 47 grade K-12 girls. We try to find possible reasons for their disengagement about physics study. In order to increase girls participation in physics related careers we try to change teachers attitude about girls engagement with physics and equipping teachers with effective pedagogical strategies to address the problem should become one of the top priorities of physics education community. This paper highlighted research literature on the reason for girls’ disengagement from physics and suggested research based pedagogies that help teaching to address this problem.
