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 experiences, like participating in science camps, existing research does not adequately address their relationship to STEM career intention later in life. Grounding our work in identity research, we tested the predictive power of STEM identity on career intention (N = 15,847). We found that for every one‐point higher on our STEM identity scale, participants’ odds of choosing a STEM career in college increased by 85%. We then tested whether a variety of childhood informal experiences predicted participants’ STEM identity. While controlling for home environment, gender, and other relevant factors, only talking with friends and family about science, and consuming science and science‐fiction media (i.e., books and television) were predictive of STEM identity in college.

With recent attention to improving scientific workforce development and student achievement, there has been a rise in effort to understand and encourage student engagement in physical science. This study examines the association of family influence and initial interest in science through multiple and logistic regression models. Research questions addressed include Controlling for demographic variables, are physical science doctoral students or scientists who report family as a primary source of interest in science, as opposed to those that do not, more likely to develop an early interest in science? And what specific forms of family support are associated with doctoral students or scientists who report family as a primary source of initial interest in science? The study uses survey data from Project Crossover (n = 4,285), a sequential mixed methods study that examines factors influencing entrance into physical science doctoral programs as well as the transition from graduate students to independent researcher. Results suggest that family interest in science facilitates earlier initial interest in science. Further analyses show that family influence shifts from parental occupation as the primary source of interest for the older generation of scientists to one of three influences (occupation, diversion or hobby, and encouragement) among doctoral students. © 2013Wiley Periodicals, Inc.

The underrepresentation of women in physics doctorate programs and in tenured academic positions indicates a need to evaluate what may influence their career choice and persistence. This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and longterm support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women's support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

Research shows that women are entering the field of physics at a faster rate than the field of chemistry through bachelor's and doctoral degrees. However, STEM studies primarily compare women to men or examine them as a single entity. Therefore, a paucity of research exists that examines what may differentiate women in certain critical and underrepresented fields of STEM education, such as the physical sciences. The focus of this study is to examine differences among women in chemistry in the physical sciences based on background demographics and motivational factors such as academic achievement and experiences ranging from secondary through postsecondary education. This study examines the following research question: On average, do females who select chemistry as compared to physics doctoral programs dif fer in their reported personal motivations and background factors prior to entering the f ield? This question is analyzed using variables in a logistic regression from the Project Crossover Survey data set through a subset of female physical science doctoral students and scientists (n = 1137). Results show that females who have higher secondary and postsecondary grades and positive experiences in postsecondary chemistry as well as negative postsecondary physics experiences are more likely to enter the field of chemistry as opposed to physics. Therefore, success and experiences in entry-level chemistry courses are critical for female entry into the field and should be further examined. Overall, analyses show that women should not be studied in comparison only to men or as a single entity; they should also be compared to one another to uncover what motivation and background variables influence them to enter a particular field.

Do summer laboratory research apprenticeships during high school have an impact on entry to MD/PhD programs? This quantitative study (n= 236,432) examines the connection between laboratory research apprenticeship experience at the high school level and matriculation into one of the more rigorous educational programs for scientific research training.
