Elementary teachers often feel underprepared to teach integrated STEM (iSTEM) and describe their preservice teacher preparation as ineffective. The purpose of this study is to investigate the extent to which semester-long STEM methods courses influenced elementary preservice teachers’ (PSTs) iSTEM teaching self-efficacy and identify how the sources of self-efficacy influenced their beliefs and confidence in teaching iSTEM. Participants included 131 PSTs at a large midwestern research-intensive public university in the United States. Quantitative data sources included the Self-Efficacy for Teaching Integrated STEM instrument administered as a pre-and post-test. The qualitative data collection included two semi-structured interviews with 10 selected participants. Findings suggest that PSTs experienced growth in iSTEM teaching self-efficacy through their STEM methods coursework. Sources that emerged as contributors toward enhanced confidence to teach iSTEM were enactive mastery, emotional arousal, vicarious experiences, and verbal persuasions. The implications for preservice teacher preparation programs and future research on iSTEM teaching self-efficacy are discussed.

Assessing how a teaching professional development program for biology graduate students bolsters self-efficacy and shapes teaching perspectives
ABSTRACT Graduate teaching assistants (GTAs) teach undergraduates directly, and many are future faculty, making it particularly important for them to be trained in using evidence-based instructional practices. We implemented and assessed a teaching professional development program for 19 biology GTAs aimed to help them develop their teaching perspectives and improve their teaching self-efficacy. The program consisted of a pre-semester bootcamp of pedagogical workshops, mentoring sessions throughout the semester, crafting a teaching philosophy statement, and reflective peer teaching observation. We surveyed and interviewed students throughout the program to assess their growth and identify elements of the program that supported their growth. We found that participants’ self-efficacy improved immediately following the pre-semester bootcamp, but these improvements did not persist throughout the semester. At the end of the semester, participants’ teaching self-efficacy did not differ from GTAs in the department who did not participate in our program. Throughout the semester, our participants shifted toward the social reform perspective of teaching, which views good teaching as encouraging students to critically evaluate information and give them power to take social action to improve their lives. At the end of the semester, our participants more strongly endorsed the social reform perspective of teaching than GTAs who did not participate in our program. Our results suggest that pre-semester workshops supported novice GTAs before their class, but more sustained interactions may be needed for these boosts to persist. Our results also suggest that encouraging GTAs to reflect on what makes good teaching can help them solidify a coherent teaching perspective.

Declining enrollments in teacher preparation programs across the United States signal a critical need for institutions of higher education to consider innovative recruitment initiatives. This pilot study investigates a novel approach to recruiting undergraduates into a teacher preparation program. Nine participants, mostly first-year college students, engaged in a year-long experiential learning program. The program provided participants with an early teaching experience in a classroom-like setting by engaging them in the collaborative development, planning, and teaching of mathematics in a summer camp for high school students. Data were collected throughout the year on their: planned major, attitudes towards mathematics and mathematics education, mathematics teaching self-efficacy, and perceptions of the program. Results showed the program was successful at improving attitudes, increasing self-efficacy, and stimulating reflection on a potential career as a mathematics teacher. Participants also shared positive impressions of the experience. Implications for research and future practice are discussed.more » « less

The Academy of Engineering Success (AcES) program employs known best practices to support engineering students with the goal of retaining them through graduation and diversifying the engineering workforce. The AcES program started in 2012 and has been supported by NSF SSTEM award number DUE-1644119 since 2016. Cohorts from 2016, 2017, 2018, and 2019 consist of 12, 20, 22, and 17 students, respectively. Twenty-one renewable S-STEM supported scholarships have been awarded to students since 2016. AcES students participate in a one-week pre-fall bridge experience, a common fall professional development course, and a course emphasizing the role of engineers in societal development in the spring semester. Starting in the bridge experience and continuing until graduation, students participate in curricular and co-curricular activities with the goals of: (1) fostering feelings of belonging in engineering and institutional inclusion, (2) encouraging professional development, and (3) supporting academic achievement and student success. These goals are achieved by providing: (1) opportunities for interaction between students and peers, faculty, and industry mentors; (2) major and career exploration opportunities; and (3) academic support and student success education in areas such as time management and study skills. AcES students participate in the GRIT, LAESE, and MSLQ surveys, as well as in focus groups and one-on-one interviews at the start and end of each fall semester and at the end of the spring semester. The surveys provide a quantitative measure of students’ GRIT, general self-efficacy, engineering self-efficacy, test anxiety, math outcome efficacy, intrinsic value of learning, inclusion, career expectations, and coping efficacy. Qualitative data from the focus group and individual interview responses are used to provide insight into the quantitative survey results. Surprisingly, a previous analysis of the 2017 cohort survey responses revealed that students who left engineering had higher baseline values of GRIT, career expectations, engineering self-efficacy, and math outcome efficacy than those students who retained. Hence, the 2018 cohort survey responses were analyzed in relation to retention and are presented along with qualitative results to provide a holistic understanding of student retention. Results from both the 2017 and 2018 cohorts are presented and discussed in the paper and poster.more » « less

Although engineering is becoming increasingly important in K-12 education, previous research has demonstrated that, similar to the general population, K-12 teachers typically hold inaccurate perceptions of engineering, which affects their ability to provide students with relevant engineering experiences. Studies have shown that K-12 teachers often confuse the work of engineers with that of automotive mechanics or construction workers or assume that engineering is only for “super smart” students who are naturally gifted or who come from higher socioeconomic backgrounds. This indicates that many teachers do not understand the nature of engineering work and have stereotypical attitudes about who is qualified to be an engineer. These inaccurate perceptions of engineering among K-12 teachers may influence the way that teachers introduce engineering practices to their students and make connections between engineering and the other STEM disciplines. In addition, teacher self-efficacy has been shown to not only influence teachers’ willingness to engage with a particular topic, but also to have a significant influence on the motivation and achievement of their students. Research also indicates that high-efficacy teachers typically exert more effort and utilize more effective instructional strategies than low-efficacy teachers. The goal of this study was to examine the perceptions that pre-service K-12 teachers hold about engineers and engineering, and to further explore how those perceptions influence their self-efficacy with teaching engineering and beliefs about what skills and resources are necessary to teach engineering in a K-12 classroom. We first developed a survey instrument that included questions taken from two previously published instruments: the Design, Engineering, and Technology survey and the Teaching Engineering Self-Efficacy Scale for K-12 Teachers. Forty-two students enrolled in an undergraduate program at {Name Redacted} in which students simultaneously pursue a bachelor’s degree in a STEM field and K-12 teacher licensure completed the survey. Based on survey responses, six participants, representing a range of self-efficacy scores and majors, were selected to participate in interviews. In these interviews, participants were asked questions about their perceptions of engineers and were also asked to sort a list of characteristics based on whether they applied to engineers or not. Finally, interview participants were asked questions about their confidence in their ability to teach engineering and about what skills and/or resources they would require to be able to teach engineering in their future classrooms. The results of this study indicated that the participants’ perceptions of engineering and engineers did impact their self-efficacy with teaching engineering and their beliefs about how well engineering could be incorporated into other STEM subjects. A recurring theme among participants with low self-efficacy was a lack of exposure to engineering and inaccurate perceptions of the nature of engineering work. These pre-service teachers felt that they would not be able to teach engineering to K-12 students because they did not personally have much exposure to engineering or knowledge about engineering work. In future work, we will investigate how providing pre-service teachers with training in engineering education and exposure to engineers and engineering students impacts both their perceptions of engineering and self-efficacy with teaching engineering.more » « less

Cameron, Carrie (Ed.)Grant writing is an essential skill to develop for academic and other career success but providing individual feedback to large numbers of trainees is challenging. In 2014, we launched the Stanford Biosciences Grant Writing Academy to support graduate students and postdocs in writing research proposals. Its core program is a multi-week Proposal Bootcamp designed to increase the feedback writers receive as they develop and refine their proposals. The Proposal Bootcamp consisted of two-hour weekly meetings that included mini lectures and peer review. Bootcamp participants also attended faculty review workshops to obtain faculty feedback. Postdoctoral trainees were trained and hired as course teaching assistants and facilitated weekly meetings and review workshops. Over the last six years, the annual Bootcamp has provided 525 doctoral students and postdocs with multi-level feedback (peer and faculty). Proposals from Bootcamp participants were almost twice as likely to be funded than proposals from non-Bootcamp trainees. Overall, this structured program provided opportunities for feedback from multiple peer and faculty reviewers, increased the participants’ confidence in developing and submitting research proposals, while accommodating a large number of participants.more » « less
