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…

Wang, Jianlan; Hazari, Zahra – Physical Review Physics Education Research, 2018
This study is focused on student recognition beliefs as related to a role identity development. More specifically, using the theoretical framework of physics identity and emotional scaffolding, we investigate the impact of two types of recognizing strategies, i.e., explicit (ER) and implicit recognizing (IR), on high school students' sense of…

Hazari, Zahra; Brewe, Eric; Goertzen, Renee Michelle; Hodapp, Theodore – Physics Teacher, 2017
Given the historic and continued underrepresentation of women in physics, it is important to understand the role that high school physics might play in attracting female students to physics careers. Drawing on data from over 900 female undergraduates in physics, we examine when these women became interested in physics careers and different sources…

Wulff, Peter; Hazari, Zahra; Petersen, Stefan; Neumann, Knut – Physical Review Physics Education Research, 2018
This study presents findings on the physics identity development of female students in the German Physics Olympiad who participated in an intervention designed to support their engagement in physics. Enrichment programs such as the Physics Olympiad have been found to positively impact students' engagement and intent to pursue a career in science.…

Potvin, Geoff; Hazari, Zahra – Physical Review Physics Education Research, 2016
There is a long history of research which confounds the simple interpretation that evaluations in an educational context are purely measures of competency. One such issue is that of gender bias in student evaluations of their teachers. In our prior work, we found that male students underrated female high school teachers in biology and chemistry…

Hazari, Zahra; Potvin, Geoff; Lock, Robynne M.; Lung, Florin; Sonnert, Gerhard; Sadler, Philip M. – Physical Review Special Topics - Physics Education Research, 2013
There are many hypotheses regarding factors that may encourage female students to pursue careers in the physical sciences. Using multivariate matching methods on national data drawn from the Persistence Research in Science and Engineering (PRiSE) project ("n" = 7505), we test the following five commonly held beliefs regarding what…

Hazari, Zahra; Cass, Cheryl; Beattie, Carrie – Journal of Research in Science Teaching, 2015
In the process of reforming physics education over the last several decades, a tension has developed between engaging students with the content in more conceptually challenging ways and helping them identify with physics so they are personally motivated in their learning. Through comparative case studies of four high school physics teachers, we…

Sadler, Philip M.; Sonnert, Gerhard; Hazari, Zahra; Tai, Robert – Science Educator, 2014
Several avenues are open to students who wish to study advanced science or mathematics in high school, which include Advanced Placement courses and teacher-designed courses unaffiliated with organized programs. We employ a retrospective cohort study of 4,691 nationally representative college students at 34 randomly selected, colleges and…

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; Sadler, Philip M.; Tai, Robert H. – Physics Teacher, 2008
The disparity in persistence between males and females studying physics has been a topic of concern to physics educators for decades. Overall, while female students perform as well as or better than male students, they continue to lag considerably in terms of persistence. The most significant drop in females studying physics occurs between high…

Schwartz, Marc S.; Hazari, Zahra; Sadler, Philip M. – Science Educator, 2008
Interview data from secondary and postsecondary science instructors explored their in-depth views on preparing students for college science. Professors expressed a high level of consensus concerning two factors: general student skills and mathematics preparation. Teachers, who expressed lower levels of consensus, did agree on the importance of…

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…

Hazari, Zahra; Sonnert, Gerhard; Sadler, Philip M.; Shanahan, Marie-Claire – Journal of Research in Science Teaching, 2010
This study explores how students' physics identities are shaped by their experiences in high school physics classes and by their career outcome expectations. The theoretical framework focuses on physics identity and includes the dimensions of student performance, competence, recognition by others, and interest. Drawing data from the Persistence…
