We examine whether and how teachers' major fields in college affect students' achievement, exploiting within-student variation across subfields in natural science (i.e. physics, chemistry, biology, and Earth science). Using middle-school students' data from the TIMSS and controlling for student-teacher fixed effects, we find that teachers improve…

Issues of equity in mathematics classrooms existed prior to COVID-19. For many students, however, meaningful participation in mathematical discussions became nearly impossible in online settings during the pandemic. In this study, we note the diversity in and nature of participation in mathematical discourse in an online course for preservice…

To fulfill the Standards for Mathematical Practice (National Governors Association Center for Best Practices & Council of Chief State School Officers [NGA Center & CCSSO], 2010), it is important for teachers to empower students to critique, revise, and expand their ideas as they solve problems. However, students often face challenges such…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction on math achievement, as measured by SBA scores. We compared "striving learner" students who were assigned to use i-Ready Personalized Instruction (Treatment students) and "striving learner" students assigned to only receive i-Ready…

In this dissertation in practice, the background of middle grades mathematics acceleration detailed why the organization benefited from a program analysis. Middle grades mathematics acceleration encourages students to take high school Algebra I in eighth grade so they can earn college-level math credits for free in high school. Often acceleration…

The purpose of this study was to measure the effect of classroom practices of using communication tools, collaboration skills, digital skills, and software skills of teachers on the communication behaviors of students during mathematics instruction. A cross-sectional online survey was conducted among 466 mathematics teachers in Nepal. The primary…

Mathematics curricula are often the primary resource used in the teaching and learning of mathematics--in particular, they represent mathematical knowledge for teachers and students. Yet, there seems to be a discrepancy between the curricular materials written for teachers and students (e.g., more variety in the semiotic choices in text provided…

In this paper, we report on data from 40 middle and secondary school mathematics teachers and teacher candidates as they begin to articulate the intersection of language-friendly pedagogy, mathematics teaching, and a multilingual technological tool by way of a two-hour introductory workshop. We use an Anthropological Theory of the Didactic which…

Students living in poverty tend to perform worse in school than their peers from better-off families. This paper examines whether computer availability helps narrow down educational inequalities in Slovakia, using TIMSS and PIRLS data. The results show that computer availability in reading lessons improves reading scores and that the effect is…

Owing to its recognition as a 21st-century skill, computational thinking (CT) is currently being introduced into school curricula around the world. However, in-service teachers are largely unprepared for this implementation, which, in turn, makes teacher educators (TEds) important stakeholders in preparing prospective teachers to integrate CT into…

This paper examines the impact of increasing teacher salaries on student outcomes by exploiting variation from the "50K The First Day" campaign that established a $50K salary floor for new teachers across New Jersey school districts. Using school-level data from 2003 to 2019, we employ a staggered difference-in-differences (DiD) approach…

The problem is that translations of language in standardized mathematics tests are not provided, which reduces the achievement scores of native-Spanish-speaking English language learners (ELLs) in Grades 4 and 8. The purpose of this basic qualitative study was to explore teachers' perceptions of language translation for the National Assessment of…

This study aims to investigate pre-service teachers' integration of technology and how the integration of technology influences the level of cognitive demands of the mathematics tasks in their mathematics technology activities. The purpose of this study was to investigate the various levels of cognitive demands of mathematical tasks created or…

In recent years, a group of teacher educators has developed a method of teacher education that incorporates practices that provide guidance about how to teach along with a principled vision of teaching that supports teachers to use the practices with judgement. Sometimes termed "core practices-focused teacher education" (Forzani, 2014,…

With the aim of strengthening mathematics teaching | learning, classroom video is increasingly used as a tool for teachers to reflect on their practice. In the first phase of a two-phase design-based study, a group of primary teachers selected, viewed and discussed video excerpts from mathematics lessons. Engaging with and working to reconcile…
