1. Re-visioning support to pre-service teachers using a lesson study model

   Hernández-Rodríguez, O.; González, G.; Villafañe-Cepeda, W. (January 2021, Productive Struggle: Persevering Through Challenges: Proceedings of the 43rd annual meeting of the North American Chapter of the International Group for the Psychology of Mathematics Education)

   The context of this study is an innovation using Lesson Study (LS) (Lewis et al., 2019) to establish connections between methods courses and clinical experiences. Although several researchers have recognized the importance of field experiences in mathematics teacher education (Bieda et al., 2015) there are few that focuses on determining mentors´ knowledge. We use four hypothetical situations to explore how mentor teachers would use their knowledge to manage problems that could surface during Lesson Study. Data was analyzed using the discursive patterns described by Horn (2010) and the Toulmin´s (1958) model.

2. Leveraging prospective teachers’ knowledge through their participation in lesson study

   This study focuses on a lesson study adaptation for bridging prospective teachers’ experiencesin a methods course and their field experiences in a teacher education program in Puerto Rico. We ask, what opportunities for teacher learning emerge during discussions in lesson study? Two lesson study teams of secondary mathematics prospective teachers, each led by an experienced mentor, planned technology-based lessons. Using the theoretical framework for lesson study by Lewis and colleagues, we analyzed video recordings of the teams’ discussions. The results show learning opportunities in the three dimensions of the framework: teachers’ knowledge and beliefs, the creation of a professional community, and the development of teaching–learning artifacts. The mentors leveraged prospective teachers’ knowledge, built on topics discussed in the methods course, and created a professional learning community. Three resources introduced in the methods course supported the creation of a hybrid space connecting academic and practitioner knowledge: shared language about teaching moves for using technology in math instruction, the mathematical proficiency framework, and a lesson plan template. The mentors drew upon their subject matter and pedagogical knowledge during their facilitation of lesson study. The intervention exemplifies a lesson study adaptation that is feasible in the context of a teacher education program.

3. THE BELIEFS AND PRACTICES OF GRADUATE STUDENT TUTORS ENGAGED IN ONLINE TUTORING DURING THE PANDEMIC

   Mule’, T; Houston, S.; Piontek, J.; Webb, J.; Harrell-Williams, L. (November 2022, Proceedings of the forty-fourth annual meeting of the North American Chapter of the International Group for the Psychology of Mathematics Education)

   Many higher education institutions in the United States provide mathematics tutoring services for undergraduate students. These informal learning experiences generally result in increased final course grades (Byerly & Rickard, 2018; Rickard & Mills, 2018; Xu et al., 2014) and improved student attitudes toward mathematics (Bressoud et al., 2015). In recent years, research has explored the beliefs and practices of undergraduate and, sometimes graduate, peer tutors, both prior to (Bjorkman, 2018; Johns, 2019; Pilgrim et al., 2020) and during the COVID19 pandemic (Gyampoh et al., 2020; Mullen et al., 2021; Van Maaren et al., 2021). Additionally, Burks and James (2019) proposed a framework for Mathematical Knowledge for Tutoring Undergraduate Mathematics adapted from Ball et al. (2008) Mathematical Knowledge for Teaching, highlighting the distinction between tutor and teacher. The current study builds on this body of work on tutors’ beliefs by focusing on mathematical sciences graduate teaching assistants (GTAs) who tutored in an online setting during the 2020-2021 academic year due to the COVID-19 pandemic. Specifically, this study addresses the following research question: What were the mathematical teaching beliefs and practices of graduate student tutors participating in online tutoring sessions through the mathematics learning center (MLC) during the COVID-19 pandemic?

4. Understanding Students’ Views of Science Identity Development

   Pedersen, D. E. (January 2022, The chronicle of mentoring coaching)

   Science identity is composed of three key components, including competence (possessing scientific knowledge), performance (the capacity to use scientific tools and language in appropriate settings), and recognition (earning validation from others in the field) (Carlone & Johnson, 2007). The significance of a strong science identity is in shaping a student’s future behavior, such as intent to graduate and pursue a STEM career (Chang et al., 2011; Chemers et al., 2011), which is particularly important for those with notable retention challenges within STEM like women, underrepresented minorities, first generation, and rural students (President’s Council of Advisors on Science and Technology, 2012). The work of building students’ science identity and encouraging their development as emerging scholars and scientists relies on both classroom experiences and the form and quality of mentoring relationships with faculty (Kendricks et al., 2013). This study considers how students see their own science identity development, and which supports they believe most central to science identity.

5. Impact of Video-Based Analysis-of-Practice Professional Learning: Comparing Online and Face-to-face Models

   Kowalski, S. M.; Belcastro, A.; Hvidsten, C.; Ollison, G.; Askinas, K.; De Vaul, R.; Roehrig, G. (September 2022, Annual Meeting for the Society for Research on Educational Effectiveness)

   Video-based analysis of practice models have gained prominence in mathematics and science teacher education inservice professional learning. There is a growing body of evidence that these intensive professional learning (PL) models lead to positive impacts on teacher knowledge, classroom instructional practice, and student learning (Roth et al., 2018; Taylor et al., 2017), but they are expensive and difficult to sustain. An online version would have several benefits, allowing for greater reach to teachers and students across the country, but if online models were substantially less effective, then lower impacts would undercut the benefits of greater accessibility. We designed and studied a fully online version of the face-to-face Science Teachers Learning from Lesson Analysis (STeLLA) PL model (Roth, et al., 2011; Roth et al., 2018; Taylor et al., 2017). We conducted a quasi-experimental study comparing online STeLLA to face-to-face STeLLA. Although we found no significant difference in elementary student learning between the online and face-to-face versions ( p = .09), the effect size raises questions. Exploratory analyses suggest that the impact of online STeLLA on students is greater than the impact of a similar number of hours of traditional, face-to-face content deepening PL, but less than the impact of the full face-to-face STeLLA program. Differences in student populations, with higher percentages of students from racial and ethnic groups underserved by schools in the online STeLLA program, along with testing of the online STeLLA model during the pandemic, complicates interpretation of the findings.
