Planning lessons and in-the-moment improvising during enactment of the plan are two central activities inherent to the practice of teaching. To what extent are these pursuits conflicting or inconsistent? What are the characteristics of improvisation during teaching and what are teachers' possible stances on it? We discuss these questions based on…

This holistic, mixed-methods action research case study aimed to determine the influence of professional development on participants' mathematical teaching practices and how the changes influenced students' opportunities for discourse. In this two-year study, participants engaged in two professional development phases and implemented new…

Modeling with mathematics (MP4) is a mathematical practice standard that can be used to engage students in mathematical content standards as well as additional mathematical practice standards. Research has shown the benefits of mathematical modeling (e.g., Aguirre et al., 2019; Cirillo et al., 2016a), but also the challenges teachers can face…

In order to compete worldwide, the school system must be transformed by raising educational standards by implementing the science, technology, engineering, and mathematics (STEM) education approach. The purpose of the primary school curriculum is closely aligned with the teaching goals of STEM education, which is to develop each child's full…

In the midst of current environmental and social crises we--educators and educational scholars--have been called to prepare our youth with the skills, attitudes, and knowledge needed to face and solve such crises. While mastery of academic content and relevant skills remain key educational goals, teachers need to be prepared and equipped to…

This study investigated the comprehensive implementation of the Multi-Tiered System of Support (MTSS) within a school district, focusing on the engagement and collaboration of educators in refining and executing MTSS strategies. The problem investigated was the effectiveness of MTSS implementation and collaboration among educators. This action…

For K-12 teachers to improve effective teaching skills, cognitive presence (CP) integration into teaching and learning process is of utmost value. CP strategy training can serve as a facilitating component in supporting K-12 teachers' instructional capacity. This study presents findings of a teacher professional development training aiming CP…

To help faculty connect programmatic assessment with the advancement of their own scholarly agenda, a professional development series was created that introduces faculty to the mutual benefits of the scholarship of teaching and learning (SoTL) and academic program assessment. An additional benefit to faculty for participating in assessment…

We sought to identify which aspects of our professional development program, the Consortium for the Advancement of Undergraduate STEM Education (CAUSE), were most useful for the participants. CAUSE was designed to support STEM faculty as they implement evidence-based teaching practices. We interviewed six faculty participants (Fellows) to address…

The EU-funded project "Supporting Mathematics and Science Teachers in Addressing Diversity and Promoting Fundamental Values" (MaSDiV) (2017-2020) promoted inquiry-based learning as a pedagogy that supports diverse and multicultural classrooms. This project included the design of a professional development (PD) programme for teachers.…

This study explored K-12 teachers' understanding and implementation of the Next Generation Science Standards (NGSS) during and after participation in a professional development (PD) program that included the development of science teachers' conceptual understanding of science. We add to the literature with our focus on a multi-year PD program…

The purpose of this study is to identify the challenges and solutions associated with implementing cooperative learning (CL), based on the lived experiences of teachers in Iran. Thirty-two primary school teachers participated in a 16-session CL workshop. However, only thirty participants were able to implement this approach in their classrooms,…

Why we need better reports of teacher professional development interventions for finding out what works where: Worldwide, billions of dollars are invested yearly in the professional development of in-service teachers ($14 billion in the USA alone, as of 2014; Bill & Melinda Gates Foundation, 2014). This makes the question of what effects TPD…

The "Guru Penggerak" program is Indonesia's "Merdeka Belajar" initiative, aiming to enhance the quality of education by equipping teachers to implement differentiated instruction (DI). This study investigates its implementation focusing on Indonesian language teachers who have been qualified as the "Guru Penggerak."…

The aim of this study is to develop a descriptive framework for teacher educators to assist teachers to plan and realize modelling implementations in their classrooms and for researchers to describe and analyse how modelling is implemented. The planning process and implementations of 12 middle and high school mathematics teachers who conducted…
