Cohen, Susie M.; Hazari, Zahra; Mahadeo, Jonathan; Sonnert, Gerhard; Sadler, Philip M. – Science Education, 2021
It is well known that women are underrepresented in science. technology engineering and mathematics (STEM) and that their interest declines more steeply over the schooling years. As such, this study uses a STEM identity theoretical framework to examine the effects of early STEM experiences, focusing particularly on experiences that may be more…

Dou, Remy; Hazari, Zahra; Dabney, Katherine; Sonnert, Gerhard; Sadler, Philip – Science Education, 2019
In this paper, we examine the relationship between participants' childhood science, technology, engineering, and mathematics (STEM) related experiences, their STEM identity (i.e., seeing oneself as a STEM person), and their college career intentions. Whereas some evidence supports the importance of childhood (i.e., K-4) informal STEM education…

Sadler, Philip M.; Sonnert, Gerhard; Hazari, Zahra; Tai, Robert – Science Education, 2012
This retrospective cohort study characterizes how interest in science, technology, engineering, mathematics (STEM) careers changes during high school for more than 6,000 students in a representative national sample of 34 two- and four-year colleges taking mandatory college English courses. Overall, large gender differences in career plans were…

Hazari, Zahra; Tai, Robert H.; Sadler, Philip M. – Science Education, 2007
The attrition of females studying physics after high school is a growing concern to the science education community. Most undergraduate science programs require introductory physics coursework. Thus, success in introductory physics is usually necessary for students to progress to higher levels of science study. Success also influences attitudes;…

Potvin, Geoff; Hazari, Zahra; Tai, Robert H.; Sadler, Philip M. – Science Education, 2009
In this study, the evaluation of high school biology, chemistry, and physics teachers by their students is examined according to the gender of the student and the gender of the teacher. Female teachers are rated significantly lower than male teachers by male students in all three disciplines, whereas female students underrate female teachers only…
