The contextual influences on technological pedagogical content knowledge (TPACK) enactment and the method of TPACK assessment remain to be important research topics. Discourse data of 81 teachers in an online professional learning community were collected and analyzed based on the framework of TPACK. Frequency distribution and time series…

Preservice teachers face the challenge of integrating multiple types of knowledge, such as pedagogical-psychological knowledge and subject-specific pedagogical knowledge. We investigated whether prior instruction emphasizing the importance of knowledge integration (relevance instruction) supports preservice teachers in using both knowledge types…

In response to calls for reformed teaching practices in college STEM labs and courses, and to support graduate teaching assistants (GTAs) in their general teaching responsibilities, other STEM disciplines have recently increased their focus on GTA training and preparation. However, current practices in GTA training in the geosciences and…

Past research indicates that teacher math anxiety is related to student outcomes and can be decreased through intervention. However, there is little research on this topic, partially due to a lack of math anxiety measures validated for use with practicing teachers. In this study of 399 elementary school teachers, we report on the construct…

Contingent argument-based approaches to validity require a unique argument for each use, in contrast to more prescriptive approaches that identify the common kinds of validity evidence researchers should consider for every use. In this article, we evaluate our use of an approach that is both prescriptive "and" argument-based to develop a…

The structure and definition of professional knowledge is a continuing focus of science education research. In 2012, a pedagogical content knowledge (PCK) summit was held and it suggested a model of professional knowledge and skill including PCK, which was later often called the Consensus Model (Gess-Newsome, 2015. A model of teacher professional…

In this exploratory study, we attempted to measure potential changes in teacher knowledge and practice as a result of an intervention, as well as trace such changes through a theoretical path of influence that could inform a model of teacher professional knowledge. We created an instrument to measure pedagogical content knowledge (PCK), studied…

The study aims to find out the influence of Mistake-Handling Activities to determine mathematical definitions knowledge, which can be regarded as a component of mathematics content knowledge, of teachers on the development of teachers in providing mathematical definitions. Within this framework, Mistake-Handling Activities were carried out with…

An increasing number of migrant teachers with a foreign teaching degree enter Swedish teacher education to complement their studies to become eligible to teach in Swedish schools. Digital competence is one of the central skills required of teachers in today's digitized information society. Within teacher education few studies examine how migrant…

This study investigates how teachers use dashboards in primary school classrooms. While learners practice on a tablet real-time data indicating learner progress and performance is displayed on teacher dashboards. This study examines how teachers use the dashboards, applying Verberts' learning analytics process model. Teacher dashboard…

On a daily basis, PreK-12 teachers make countless decisions about how to best meet their students' needs through assessment and instruction. However, their ability to justify these decisions is not frequently used as a resource for accountability measures or the evaluation of educational programs. The research presented here, which draws from a…

In this study, the authors propose a set of design principles based on the framework of Technological Pedagogical Content Knowledge (TPCK or TPACK) through the subject matter of music focusing on the affective domain, and identify interrelations among musical content, emotions, and technology. The design guidelines were tested in an empirical…

The current study aims to examine meanings and error types associated with pre-service elementary teachers' semi-structured problems for the multiplication and division of fractions. A total of 83 junior pre-service elementary teachers were recruited in the spring semester of the 2016-2017 academic year. A researcher-developed Problem Posing Test…

Scientific data visualizations are the products, and increasingly a core practice, of modern computational science across all domains. With recent science education standards emphasizing student engagement in practices, these scientific visualizations will only increase in their availability and use for K-12 science instruction. But teacher…
