After years evaluating teacher professional learning programs, researchers Andrew J. Wayne, Jordan Rickles, Mengli Song, Seth Brown, and Michael S. Garet describe a study that changed their perspective. The study's takeaways about the design of teacher professional learning are important for everyone who seeks to create systems to support teaching…

In this three-article dissertation, I explore what it means for teachers to be designers in three different ways. Each article can stand on its own, but taken together, they paint a rich and nuanced picture of the relationship between teachers and design. The first article is an analysis of a decade of literature on teachers and design seeking to…

Designing tasks to foster students' learning is challenging for teachers. In this article, we aim to understand how designing, enacting, and reflecting on tasks promotes the development of in-service and prospective teachers' didactical knowledge during lesson study. Data was collected through participant observation with audio recordings and…

The phenomenon of teachers designing their own instructional materials is gaining more attention in research. Different aspects of this enterprise have been examined--its potential to reveal the complexity of teachers' instructional planning considerations, the design principles employed by teachers to realise instructional goals, among others. In…

In recent years, the integration of STEM disciplines has been increasingly advocated. It is crucial to prepare and support teachers for integrated STEM education. However, few studies in the literature explore collaborating with teachers from different disciplines. This study investigates the effect of the professional development (PD) program…

With this study we aimed to evaluate the effectiveness of a collaborative and reflective school-based training model on the teachers' professional transformation in a middle school in Turkey. This study emerged as a result of a need for this school to transform its instructional approach to the understanding by design (UbD) approach. Considering…

In this paper, we describe the design, development, and implementation of a curriculum based on teaching computer science using an industry-standard game-design software: Unity 3D. We discuss the theoretical underpinnings of our instructional design process and steps we have taken to introduce complexity and maintain student motivation. We discuss…

This paper describes an Online Teaching Lab model that incorporates elements of lesson study and studio model for teacher learning. We focus on changes in design and facilitation decisions of two specific Online Teaching Labs and study differences in teachers' verbal and written responses to better understand how the process supports teacher…

We investigate the beliefs that influence middle and high school algebra teachers' appraisals of contextual problems having diverse mathematical and pedagogical features. We asked six teachers to analyze six contextual algebra tasks and indicate how they would apportion instructional time among the six tasks based on their structure, pedagogical…

In the 2024 legislative session, the Tennessee General Assembly passed Chapter 551 of the Public Acts of 2024 (PC 551), the Mathematics Supports Act (the Act), codified at Tenn. Code Ann. §§ 49-1-233 -- 49-1-234. The Act indicates the General Assembly's commitment to strong mathematics instruction in Tennessee to prepare students for postsecondary…

The need and desire to understand and adopt formative assessment practices remain high on the agenda at all levels of educational systems around the world. To advance teachers' use of formative assessment, research attention also needs to be paid to (a) understanding the challenges teachers face when asked to utilize formative assessment practices…

One-to-one computing programmes -- that is, when each student has a personal, portable computer to use while learning -- have been studied extensively, mostly regarding their actual classroom implementation. In this quantitative study, the authors take a broader perspective, exploring the impact of teaching in one-to-one computing programmes on…

This design-based research investigated the context and impact of a three-year practice-based professional development (PD) project introducing science teachers to pedagogical shifts required for full implementation and synergy among disciplinary literacy components of "Next Generation Science Standards" and "Common Core State…

In this working group, we continue with previous efforts to consider design and research methodologies related to teacher learning in online professional development contexts. We then describe an innovative project designed to support the development of middle school mathematics teachers, with a focus on three distinct forms of online learning:…

STEAM (science, technology, engineering, art, and mathematics) education is gaining popularity in schools across the United States and in parts of Europe, Asia, and Australia. Despite its popularity little empirical data exists to guide effective instructional practices, and even less is known about the challenges associated with instruction.…
