Researchers have typically identified and characterized teachers' knowledge bases (e.g., pedagogical content knowledge and subject matter knowledge) in an effort to improve enacted instructional strategies. As shown by the Refined Consensus Model (RCM), understanding teacher learning, beliefs, and practices is predicated on the interconnections of…

This article describes a 'research project' at a girls school where teachers wanted to improve their students' engagement and interest in mathematics. Conversations with the students indicated they thought mathematics was difficult but also repetitive and boring, with lessons that had little variety of tasks. While some students like to learn…

In Sweden, although all teacher education programs require the completion of the practicum, little focus has been placed on consistent evaluation of how content knowledge is included and built during practicum lessons, or how lesson planning and teaching are aligned. This article presents a novel method for teacher educators, mentors, and student…

Lesson study, a popular method of professional development in which instructors collaborate to critique and improve a lesson, can be used for curriculum development. This paper describes an implementation of lesson study that went through two iterations across different, related, contexts: an undergraduate mathematics content course for secondary…

This article presents a story of practice regarding how a primary school addressed the issue of supporting English as an additional language or dialect (EAL/D) learners to communicate and reason in mathematics. A shared understanding across the school uncovered teachers have a critical role in supporting EAL/D learners and their acquisition and…

Measures of teacher mathematical knowledge are notoriously difficult to develop (e.g., Orrill et al., 2015). This is in part because of the multidimensional nature of teacher knowledge. As part of two separate projects being undertaken by this research team, we have attempted to write assessments of teacher pedagogical content knowledge (PCK) in…

This article examines the professional knowledge required for mathematics teachers to effectively use generative artificial intelligence (GenAI) in planning high-quality, ambitious mathematics lessons. While GenAI tools like ChatGPT offer promise for automating parts of lesson planning, their utility in supporting ambitious instruction is limited…

Sam Pullan explains how a chance encounter has helped him to improve his introduction to the modern themes and founding documents of US politics. Working with a professional historian whom he met, by chance, over dinner, he was able to produce lessons at the cutting edge of subject knowledge to grab the attention of his Year 11 pupils. This…

Diane Relf was concerned by what felt like an unbridgeable gulf between Year 7's vocabulary and comprehension, and her aspirations both for their inclusion in history and their later academic success. As a subject leader without the benefit of any history-specific training at the start of her career, she embarked on a journey of intensive reading…

Moreover, the cross-curricular integrative writing approach implemented by the instructors of these courses (the authors) provided students enrolled in the Colleges of Education and the College of Social Sciences, Arts, & Humanities a unique opportunity to become actively engaged in a multidisciplinary approach to learning. The assignment not…

Lesson study (LS) is a form of professional development, with a strong foundation in mathematics education, based on teachers collaborating to design lessons. This collaboration, however, can be challenging for isolated teachers. In 2017, a course was presented at the university to train 52 teachers from all over South Africa as well as Botswana…

Learning to teach students with disabilities is challenging. Preservice special educators must develop critical knowledge of content as well as skill for enacting evidence-based practices effectively. Preservice special educators need increased opportunities to learn core knowledge coupled with a mechanism to support them in situating their newly…

The purpose of this paper is to describe the professional development that has taken place in conjunction with Ohio adopting the College and Career Readiness (CCR) Standards. The professional development (PD) has changed over time to include not only training on the new standards and lesson plans but training on the concepts defined in the…

The Ghanaian mathematics curriculum expects teachers to adopt technologies as an instructional tool to assist students to learn mathematics relationally. Teachers' dispositions (knowledge, beliefs, and attitudes) towards technology are critical in translating the curriculum intention into practice. This paper presents teachers' initial…

For many teachers, engineering can be intimidating; teachers receive little training in engineering, particularly those teaching early elementary students. In addition, the necessity of differentiating for students with special needs can make engineering more challenging to teach. This article describes a professional development program…
