Building Primary Preservice Teachers’ Identity as Engineering Educators
(MDPI AG, 2022-09) Lux, Nicholas; Hammack, Rebekah; Wiehe, Blake; Gannon, Paul
The purpose of this qualitative case study was to investigate how two primary preservice teachers built their engineering education identities during a clinical field experience that emphasized engineering education. More specifically, we explored the development of their engineering education identities while facing unforeseen circumstances and unfamiliar engineering content. We used a nested qualitative case study approach that was bounded by a university practicum field experience that took place at the height of the COVID-19 pandemic. Data sources included preservice teacher interviews and reflective field notes. We found that the preservice teachers faced a series of contextual factors in the clinical experience that both afforded and constrained professional learning opportunities that influenced their identity development. The affordances made professional learning opportunities possible, while the constraints limited professional growth. We also found that it was the negotiation of the factors, where the preservice teachers worked to mitigate the effect of the constraints while maximizing the advantages of the affordances, that had the greatest influence on their engineering pedagogical knowledge and engineering teaching self-efficacy. Findings from this study could provide teacher educators with insight into preparing primary teachers for unexpected challenges when teaching engineering, as well as how to best prepare engineering-efficacious teachers.
Elementary teachers' perceptions of K-5 engineering education and perceived barriers to implementation
(2019-04) Hammack, Rebekah; Ivey, Toni
Background The Next Generation Science Standards (NGSS) call for the integration of engineering content and practices in elementary science curricula, yet little is known about elementary teachers' preparedness to do so or their views on teaching engineering. Purpose/Hypothesis The purpose of the current study was to explore K‐5 teachers' perceptions about incorporating engineering in their classrooms as well as the perceived barriers for doing so. Design/Method This study consisted of an online survey including a mix of selected response, Likert, and short answer items, followed by individual interviews and focus group sessions with a subset of survey participants. Descriptive statistics are reported for quantitative survey data. Open‐ended survey questions as well as interview and focus group transcripts were inductively coded to identify emergent themes. Results Many elementary teachers support the inclusion of engineering in the science standards for elementary grades. Teachers describe a lack of preservice and in‐service training, background knowledge, materials, time for planning and implementing lessons, and administrative support as barriers to implementing engineering activities within their classrooms. Conclusion While many elementary teachers support the use of engineering activities in their classrooms, there are numerous barriers preventing them from doing so. To ensure that NGSS are incorporated into elementary classrooms as they were intended, elementary teachers must be provided with the necessary training, resources, and support.
Enhancing engineering education in the elementary school
(2019-04) Utley, Juliana; Ivey, Toni; Hammack, Rebekah; High, Karen
The Next Generation Science Standards emphasizes the inclusion of engineering practices throughout the K–12 science curriculum. Therefore, elementary educators need to be knowledgeable about engineering and engineering careers so that they can expose their students to engineering. The purpose of this study was to examine the effect of engineering professional development on in‐service elementary teachers’: (a) knowledge and perceptions regarding engineering, and (b) self‐efficacy of teaching engineering. This quantitative study revealed that even one professional development opportunity can help to alleviate some misconceptions about the work of engineers and what constitutes technology, as well as increase teachers’ confidence to teach engineering concepts.
“Step Outside”: A portrait of an exemplary rural K‐8 science educator
(Wiley, 2022-08) Hammack, Rebekah; Stanton, Christine Rogers; Boyle, Judith
This study uses portraiture methodology to co-construct and share the story of a nationally recognized rural K-8 science teacher with more than 30 years of teaching experience. Our analysis and synthesis revealed one central theme “Step Outside” and three subthemes: (1) Step Outside of the rural classroom, (2) Step Outside of the K-8 teacher's comfort zone, and (3) Step Outside of science silos, that have been central to the teacher's personal and professional journey. Examining the ways, these subthemes have intersected across the career of an exceptional rural teacher offers valuable insight to the development of teacher identity and how it shapes practice and research, especially within marginalized contexts such as K-8 science education and rural settings.
