Chemistry is considered a difficult subject by most students. Its difficulty lies in Chemistry's complex and abstract nature. This highly abstract nature requires constant interplay and coordination between the macroscopic, particulate, and symbolic representations. Experts can successfully navigate the various representations without overloading…

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;…

Computational thinking (CT) and modeling are authentic practices that scientists and engineers use frequently in their daily work. Advances in computing technologies have further emphasized the centrality of modeling in science by making computationally enabled model use and construction more accessible to scientists. As such, it is important for…

This study reports the results of a mixed-methods investigation on the impact of a virtual reality (VR) tool on Iranian EFL learners' willingness to communicate (WTC) and oral proficiency. Twenty upper-intermediate EFL learners were divided into experimental and control groups role-playing as museum guides with and without Google Expeditions VR…

The United States' Next Generation Science Standards (NGSS) elevate engineering design to the same stature as scientific inquiry, calling on science teachers to engage students in engineering practices to solve real-world problems. In response, researchers and curriculum developers designed and studied Virtual Engineering Internships (VEIs) to…

This article investigates research approaches used in traditional classroom-based interaction studies for identifying a suitable research method for studies in three-dimensional virtual learning environments (3DVLEs). As opportunities for language learning and teaching in virtual worlds emerge, so too do new research questions. An understanding of…

The article presents research findings on the professional growth of three in-service EFL teachers from Germany who took part in a teacher education programme centred on technology-mediated plurilingual education. The study investigated how the programme influenced the development of the teachers' pedagogical and digital skills in creating and…

Using a low-inference observation instrument, we investigated the effect of an ongoing, intensive, and structured virtual professional development (VPD) based on the fidelity of implementation (FOI) across treatment and control conditions in a randomized controlled trial validation study implemented in 116-bilingual classrooms in seven Texas…

The study reported in this article investigated the influence of a research-informed, school-based, professional development workshop programme on the quality of classroom dialogue using the interactive whiteboard (IWB). The programme aimed to develop a dialogic approach to teaching and learning mediated through more interactive uses of the IWB,…

Mathematical Argumentation skills have historically been overlooked in assessment, but the inclusion of Mathematical Argumentation in the Common Core State Standards (CCSS) as one of the Standards of Mathematical Practice challenges assessment developers to assess this mathematical practice. Explanation and justification of one's own thinking to a…

The study explores how a complexity approach empowers science learning. A complexity approach represents systems as many interacting entities. The construct of micro-macro compatibility is introduced, the degree of similarity between behaviors at the micro- and macro-levels of the system. Seventh-grade students' learning about gases was studied…

This dissertation study focused on complications and opportunities that surface for classroom learning in the intersections of a teacher's methods, students' literacies, and digital space. Though researchers have discussed adolescents' literacies and participation in out-of-school digital spaces, there persists a need to explore and document the…

This paper provides a description and rationale for a performance assessment of a teaching practice--leading a classroom discussion (LCD)--included in the ETS® National Observational Teaching Examination (NOTE) assessment series. In this assessment, candidates interact with a small class of virtual students represented by avatars in a…

This report describes and provides research and scholarly support for a core practice of teaching--eliciting student thinking (EST)--that is the target for a performance assessment contributing one component of the "ETS"® National Observational Teaching Examination (NOTE) assessment series. The purpose of this report is to review the…

This report reviews the scholarly and research evidence supporting the construct labeled modeling and explaining content (MEC), which is measured via a performance assessment in the "ETS"® National Observational Teaching Examination (NOTE) assessment series. This construct involves practices at the heart of teaching that deal with how…
