In this study, three math and three science teacher educators (TEs) were positioned as designers of instruction. The investigation considered how TEs supported preservice teachers (PSTs) to learn to facilitate argumentation discussions using two digital simulations. Research questions were (a) How did TEs engage in instructional design around the…

Advancements in computing have led to increased interest in integrating computational thinking in the K-12 curriculum. Computational thinking can be defined as a problem-solving process with the goal of developing algorithms that can be coded for computer use. With its emphasis on problem solving, the processes associated with computational…

This qualitative study investigated how mixed-reality simulations supported the development of justice-oriented core teaching practices within a large elementary education program. Told from the point-of-view of two methods instructors, using candidates' written and oral reflections, the authors examined the use of Mursion[R] mixed reality…

Extended reality experiences for mathematics teachers can allow them to understand both pedagogy and the mathematics itself in new ways. In this study, the authors explored a virtual reality simulation for learning about geometric shapes, where teachers could engage in joint, shared manipulation of holograms in three dimensions. The authors…

Structures such as rehearsals have been designed within mathematics education to engage teacher candidates in deliberate practice of specific teaching episodes before enacting within classroom settings. Current research has analyzed traditional rehearsals that involve peers acting as K-12 students as the teacher candidate facilitates an activity;…

Supporting teachers' implementations of technology in the classroom is a critical and longstanding issue in mathematics education. As access to various technology resources grows, a need exists for professional development opportunities that prepare teachers to integrate technology effectively to support students' mathematical learning…

The third pillar of technology infusion is practice, providing numerous opportunities in multiple settings for teacher candidates to practice teaching with technology and to reflect on their experiences. Drawing from sociocultural theories of learning and change, this article offers a theoretical justification of this pillar and unpacks how…

In this report of an action research study, the authors describe how one elementary science teacher educator used transcript coding of simulated classroom discussions as a pedagogical approach to learn about her elementary preservice teachers' (PSTs') abilities to notice key aspects of scientific argumentation discussions. Elementary PSTs (n = 19)…

This article describes the results of a retrospective study of preservice teachers' ability to plan learning experiences that integrated an immersive virtual reality (VR) technology. The study was conducted over multiple academic terms as VR technology featuring a head-mounted display (VR HMD) was evolving from a prototype to a commercially…

This article describes the Infusing Computing project, a 4-year study designed to support middle and high school teachers in infusing computational thinking (CT) into their disciplinary teaching. Due to the COVID-19 pandemic, weeklong workshops held in summer 2020 were shifted to a virtual format and utilized emerging technology tools, synchronous…
