Informal Science: Family Education, Experiences, and Initial Interest in Science.

Recent research and public policy have indicated the need for increasing the physical science workforce through development of interest and engagement with informal and formal science, technology, engineering, and mathematics experiences. This study examines the association of family education and physical scientists’ informal experiences in science along with the association of informal family science experiences and early initial interest in science through multiple and logistic regression analyses. Research questions addressed are as follows: Controlling for demographic variables, do physical scientists parents’ level of education associate with participation in informal family science experiences? And which informal family science experiences are associated with physical scientists that report an initial personal interest in science by elementary school? These questions are analyzed with 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 indicate that families with higher parental education are more likely to take part in informal science experiences and therefore more likely to provide positive encouragement for their children to develop an early interest in science. Detailed analyses show that the following family forms of informal science education: occupation, diversions and hobbies, and encouragement are associated with an early initial interest in science by elementary school.

Examining Summer Laboratory Research Apprenticeships for High School Students as a Factor in Entry to MD/PhD Programs at Matriculation.

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.

The Bachelor’s to PhD Transition: Factors Influencing PhD Completion Among Women in Chemistry and Physics

Existing research has examined if undergraduate factors influence chemistry and physics, or physical science, doctoral degree entry and whether variables during PhD programs associate with graduation. Yet research on the transition from bachelor’s degree to doctoral degree entry (i.e., PhD entry in less than 6 months, attainment of a master’s degree prior to doctoral degree entry, or working in a science-related job for more than a year prior to doctoral degree entry) on PhD degree graduation remains scarce. Our study examines the transition from bachelor’s to doctoral degrees to see if experiences therein associate with female PhD graduation, after doctoral degree enrollment. Our logistic regression analysis, of female chemistry and physics doctorates (n = 867), indicated that attainment of a master’s degree did not change the likelihood of graduation, when compared to direct entry into physical science doctoral programs. Meanwhile working in a science-related job for a year or more is associated with a significantly lower likelihood of physical science doctoral graduation when compared to women who entered directly into PhD programs or received a master’s degree prior to enrollment.
