A central aspect of reform-minded mathematical teaching is training and developing teachers' ability to notice vital aspects in the classroom and more specifically, students' mathematical thinking. As there is an abundance of evidence and research that support the benefits for teachers to elicit and use students' ideas and thinking during…

Computational thinking (CT) has great potential for enhancing mathematics and science lessons in K-12 education. Numerous studies demonstrate that under the right circumstances, CT integration in math and science can improve student learning and promote deeper understanding. However, teacher education currently does not include preparation for…

Research has shown that teachers and students have difficulties in connecting climate change evidence with climate change claims. Such difficulties may come from the lack of knowledge about how scientific models and modeling work in climate science. Climate change as a complex system with a large time and land scale requires sophisticated…

Learners need to develop multifaceted skills and knowledge in order to productively engage with today's increasingly uncertain world. To this aim, science educators strive to build students' science knowledge by engaging them in scientific practices, such as collaborative inquiry, which are social and collaborative in nature. However, learners…

Preservice educators are required to enroll in multiple methods courses to prepare them to effectively teach content to students. With the increase of online teacher preparation programs, methods courses are also being offered virtually. This study sought to investigate the overall attitudes, beliefs, and preparedness of candidates after…

The impact of the "Next Generation Science Standards (NGSS)" on K-12 science education has gained significant momentum over the last several years. Evidence of the "NGSS" can be seen in revised state science content standards and amended teacher preparation standards. Due to this growing impetus, a holistic redesign of teacher…

Scientific modeling is a scientific practice that uses models to prepare elementary and middle school science teachers to engage students using scientific inquiry. Model-based inquiry (MBI) is a pedagogical teaching approach that engages students using scientific inquiry during scientific modeling. However, preservice teachers lack understanding…

The purpose of this study was to explore four elementary preservice teachers' (PSTs) learning outcomes based on "affective characteristics," "science knowledge," and "pedagogical content knowledge" during a science methods course that incorporated "explicit instruction on drawing-to-reason" about…

In this study, I conducted three separate, but interrelated studies that examine the ways preservice teachers (PSTs) generatively developed youth-centered, equity-oriented pedagogical imaginaries in their methods courses and how they enacted these practice(s) in their field experiences. The purpose of this dissertation is to understand how and in…

Background: English language learners (ELLs) are dramatically increasing in U.S. schools: by 2025, 25% of public school students will be ELLs (NEA, 2018). In one teacher education program in the Southeastern U.S., all students earning teacher certification must complete a course in second language methodology. This study seeks to understand…

This dissertation explores the post-hoc programmatic outcomes and experiences of participants in a large scale, grant-funded professional development (PD) program. This PD was an immersive, two-year induction program designed to improve state testing scores in science, and support early career science educators as they transitioned into the…

This study utilized a semi-structured interview approach to identify how college methods professors in Nebraska are engaging pre-service K-12 teachers with the Next Generation Science Standards and to determine if this information is being carried over to Nebraska K-12 classrooms. The study attempted to address these items by answering the…

The development of scientifically literate citizens begins in the elementary school. Yet elementary school teachers are ill prepared to teach science (Trygstad, Smith, Banilower, Nelson, & Horizon Research, Inc., 2013). The research base on teacher preparation finds that programs designed to prepare elementary teachers are inadequate in…

Elementary teachers are criticized for failing to incorporate meaningful science instruction in their classrooms or avoiding science instruction altogether. The lack of adequate science instruction in elementary schools is partially attributed to teacher candidates' anxiety, poor content and pedagogical preparation, and low science teaching…

In this dissertation, the researcher describes authentic scientific inquiry (ASI) within three stages of teacher preparation and development: a1) undergraduate STEM courses, b2) preservice secondary science education methods courses, and c3) inservice teacher professional development (PD). Incorporating (ASI)--pedagogy closely modeling the…
