   The AP Computer Science A course and exam continually exhibit inequity among over- and under-represented populations. This paper explored three years of AP CS A data in the Chicago Public School district (CPS) from 2016-2019 (N = 561). We analyzed the impact of teacher and student-level variables to determine the extent AP CS A course taking and exam passing differences existed between over- and under-represented populations. Our analyses suggest four prominent findings: (1) CPS, in collaboration with their Research-Practice Partnership (Chicago Alliance for Equity in Computer Science; CAFÉCS), is broadening participation for students taking the AP CS A course; (2) Over- and under- represented students took the AP CS A exam at statistically comparable rates, suggesting differential encouragement to take or not take the AP CS A exam was not prevalent among these demographics; (3) After adjusting for teacher and student-level prior experience, there were no significant differences among over- and under-represented racial categorizations in their likelihoods to pass the AP CS A exam, albeit Female students were 3.3 times less likely to pass the exam than Males overall; (4) Taking the Exploring Computer Science course before AP CS A predicted students being 3.5 times more likely to pass the AP CS A exam than students that did not take ECS before AP CS A. Implications are discussed around secondary computer science course sequencing and lines of inquiry to encourage even greater broadening of participation in the AP CS A course and passing of the AP CS A exam.

2. Preparing Pre-Service Teacher Candidates for the Praxis Exam: An Innovative Model of Blended Support

   The expansion of K-12 computer science (CS) has driven a dramatic need for educators who are trained in CS content and pedagogy [1]. This poster describes our effort to train teacher candidates (i.e., pre-service teachers who are students seeking degrees within a College of Education), who are specializing in secondary mathematics education, to be future CS educators. We specifically describe our collaboration to provide a blended preparatory six-week training for the ETS CS Praxis exam (5652), assisting our pre-service students in satisfying the CS certification requirements in our state before they graduate and begin their professional teaching career. Given the unique challenges of pre-service CS teacher preparation [2], blended models, which combine both in-person and online instruction, are an effective approach to building a pre-service program. Within our pre-service CS program, students first complete a two-course pathway that prepares them in AP CSP content and pedagogy experiences, including observations in local AP CSP classrooms [3]. After completing the two courses, our students participate in the blended version of the WeTeach_CS Praxis preparation course to achieve certification. The in-person support provided by the blended model contributed significantly to certification success in this project. With a cut-score of 149 for the Praxis exam, all 11 of our pre-service students who completed the course received a passing score (including one student with a perfect score of 200, and another student with a 195); the average score for our pre-service students was 175. An additional 11 in-service teachers, with diverse backgrounds in CS content knowledge, also participated in the blended Praxis preparation course, with an average score of 166. Given the unique challenges of pre-service CS teacher preparation, university pre-service CS teacher programs should look to innovative models of teacher support developed by in-service programs to make substantial gains in CS teacher certification. Incorporating an asynchronous online course that allows teachers with a wide range of prior experience in CS to learn at their own pace with in-person coursework and support appears to be a viable model for assisting non-CS major teacher candidates in achieving a CS certification. With the blended model, even teachers with no background knowledge in CS were successful.

3. Strengthening STEM Teaching in Rural, Indigenous-Serving Schools through Long-Term, Culturally Responsive Professional Development

   This paper describes a particular teacher professional development model offered in schools on and bordering the Navajo Nation in the southwestern United States. The Diné Institute for Navajo Nation Educators (DINÉ) offers professional development across all content areas and grade levels, but here we focus specifically on our work in science, technology, engineering, and mathematics (STEM) content areas. Our work is situated explicitly within the literatures on Indigenous education, Native Nation Building, and culturally responsive schooling, but we also draw broadly on research in STEM education and teacher professional development. The research question explored in this paper is: To what extent and in what ways do teachers in the DINÉ develop STEM curriculum units that evidence culturally responsive principles and STEM education best practices? We share findings from three cohorts of teachers in the DINÉ’s STEM-focused professional development seminars. Teacher-authored curriculum units developed in the DINÉ were analyzed with two specific protocols: the CRAIS Tool, and the SCOOP notebook. Finally, we look closely at the curriculum units written by a single teacher in the DINÉ across the three years in order to get a clearer understanding of the nuances and richness of the findings and themes reported from the aggregate data.

4. Developing Equity Literacy and Critical Statistical Literacy in Secondary Mathematics Preservice Teachers

   https://doi.org/10.5951/MTE.2021.0015  

   Casey, Stephanie; Ross, Andrew (September 2022, Mathematics Teacher Educator)

   There is a lack of teacher education materials that develop equity literacy in content courses for preservice secondary mathematics teachers. In response, we created teacher education curriculum materials for introductory statistics that include an integrated focus on developing equity literacy and critical statistical literacy. In this article, we provide an overview of our materials’ design along with a detailed look at one activity regarding racial demographics and tracking in high school STEM courses. We present evidence regarding the positive impact of these materials on the teacher candidates’ competency, value, and likelihood of applying their equity literacy and critical statistical literacy. Implications for mathematics teacher educators working to develop equity literacy together with content knowledge are discussed.

5. STEM Teacher Characteristics and Mobility: Longitudinal Evidence From the American Midwest, 2010 Through 2023

   ABSTRACT This study examines the demographics, qualifications, and turnover of STEM teachers in Kansas and Missouri—two contiguous, predominantly rural states in the Midwestern region of the United States. The existing literature lacks detailed insights regarding U.S. STEM teachers, especially with recent economic and social changes over the COVID‐19 pandemic, and there is particularly limited evidence regarding STEM teachers in the U.S. Midwest. Utilizing large‐scale administrative longitudinal data, we filled part of this gap by documenting the characteristics and turnover patterns of STEM teachers in Kansas and Missouri over a 13‐year period, from 2010 through 2023. Our analysis shows declining trends among young and early‐career STEM teachers, STEM certification, and rising STEM teacher turnover, especially post‐COVID‐19. We found particularly high turnover rates in urban schools and schools with the highest shares of students of color and poverty. We also found numerous factors of STEM teacher turnover, including salary and employment in schools serving high percentages of minoritized and low‐income students, as well as differential turnover patterns among school geographical circumstances. This work is the first comprehensive examination of STEM teachers in Kansas and Missouri. We offer insights into the teacher workforce of the traditionally overlooked U.S. Midwest. Our results suggest important policy implications for sustaining a diverse and qualified STEM teacher workforce in the U.S. amid post‐COVID‐19 social changes, thereby informing decision making at state and national levels that aim to foster equitable access to high‐quality STEM education among students in diverse contexts, while contributing to the U.S.'s long‐term economic growth, sustainability, and the world's advancement of STEM education.
