It is widely accepted that the classroom teaching practices of in-service secondary mathematics teachers can benefit from the advanced mathematics they learned during their university education. However, pinpointing explicit instances of how this advanced knowledge informs teaching practices has proven challenging for both teachers and…

Research indicates that investigating phenomena, rather than reproducing facts, should be a core experience in the education of prospective mathematics teachers. Corresponding with its centrality to quality teacher education, there are multiple existing methodologies for analyzing the effects of investigation tasks on teachers' mathematical…

In this article, we describe rehearsals designed for use in professional development (PD) with secondary mathematics teachers to support them in reimagining and refining their practice. We detail a theoretical framework for learning in PD that informs our rehearsal design. We then share evidence of secondary mathematics teachers' improvements in…

Due to the increasing presence of the Science, Technology, Engineering, and Mathematics (STEM) education paradigm in Spain, many teachers have embarked on the design of specific Teaching--Learning Sequences (TLS) to be implemented in schools. Understanding the views and perceptions about STEM that take shape in specific teachers' designs should…

Practitioner enquiry is a well-established approach to professional learning that can facilitate teachers' pedagogical knowledge and improve their educational practice. That said, practitioner enquiry is less frequently seen in physical education (PE) initial teacher education and in the general practice of PE teachers. This study examines the…

The study assessed, designed, developed, validated, implemented, and evaluated the effects of the e-training package on TPACK. The study was conducted at Bukidnon State University from 2021-2022. Using Research and Development, an e-training package on TPACK involved Content Knowledge, Technological Knowledge, and Pedagogical Content Knowledge was…

Many researchers have studied who and what teachers notice from video and some have focused on the analytic stance of teachers, meaning how noticing occurs. We complement existing work with a focus on analytic stance in a particular mathematics domain, proportional reasoning. We engaged 30 practicing teachers in an online course that included…

Education leadership models must stay current to facilitate teacher professional development. The way in which K-12 education is delivered and how teachers approach instruction must evolve to meet the changing needs of students. Referencing the Leader-Member-Exchange Theory framework, the researcher conducted a mixed-methods study that implemented…

Studies have documented numerous positive effects of mentoring, but few studies have focused on mentor education and mentors' professional development and learning. In Norway, the focus on mentoring and mentor education has been visible in political documents and teacher education for several years. However, the scale of mentor education has been…

Understanding teacher candidates' (TCs') developmental needs and framing teacher preparation with those in mind can provide education programs with actionable ways to further TC development that generate positive outcomes for them and their students. This novel case study explored four initial certification TCs' teacher performance and stages of…

Understanding and affirming the assets of emerging bilingual learners (EBLs) and resources are often not part of preservice teacher (PST) preparation, particularly for preservice secondary teachers (Newman et al., 2010). The authors of this article designed two Grand Seminars to support PSTs to begin to develop a translanguaging mindset and to…

This study aims to test the content and face validity of Secondary School Islamic Education Teacher Self-Assessment Instrument (SSIET-SAI) using Content Validity Ratio (CVR), Content Validity Index (CVI) and Cohen Kappa Index (CKI) analysis. They are nine professional experts from universities and schools and two other expert field. Validation…

Our complex world requires multivariate reasoning to make sense of reality. Within this paper, we offer a sequence of activities designed to develop multivariate reasoning by explicitly connecting data and visualization. The activities were designed based on a hypothetical learning trajectory we conjectured for students with limited experience…

Robust school-university partnerships can create continuous systems of educator learning that focus on systemic change and the simultaneous renewal of both educators and the organizations within which they work to improve outcomes, opportunities, and access for P-12 students and their teachers. This article is a case of the Project PREP…

Initial pre-service teacher training should include insights and learning that are closely related to classroom practice. In this paper, we analyse the expectations voiced by pre-service teachers studying toward a master's degree in secondary education as well as by in-service teachers. Both groups participated in a 6-month professional…
