This article presents an extension of the well-known TPACK model to describe the professional digital competencies of mathematics teachers. The extension leads to what we want to call MPC-model (Media-Pedagogy-Content) in the following. It additionally includes (1) the consideration of competencies instead of knowledge for a holistic description,…

The purpose of the study is to evaluate how prospective mathematics teachers (PMTs) modify tasks to facilitate students' learning of pattern generalization through the use of their mathematical knowledge for teaching. Case study, which is a type of qualitative research method, was used to determine the mathematical characteristics that PMTs use…

Online learning continues to grow at unprecedented rates. K-12 had more than 275,000 students enrolled in full-time virtual schools in 2011--2012 and over 2 million participating in at least one online course. Despite this growth, there is little research on model formation and model validation for online learning. Two research-based models were…

Social studies continues to be marginalized in elementary grades, yet the "C3 Framework" and its Inquiry Arc offer possibilities for high-quality elementary social studies instruction. However, the "C3 Framework" requires that teachers possess an adequate understanding of how to implement inquiry within the various social…

This paper reports a case study of four grade 10 physical sciences teachers' PCK about graphs of motion. We used three data collection strategies, namely teachers' written accounts, captured by the content representation (CoRe) tool, interviews and classroom observations. We conceptualised the PCK displayed in the CoRe tool and the interviews as…

This case study enabled researchers to understand the knowledge embedded in a world language teacher's enactment of content-based instruction (CBI) through the lens of a theoretical model inspired by Shulman's (1987) construct of pedagogical content knowledge (PCK). The model, called integration pedagogical content knowledge (I-PCK), represents an…

Great teaching is characterised by the specific actions a teacher takes in the classroom to bring about learning. In the context of model-based teaching (MBT), teachers' difficulty in working with students' models that are not scientifically consistent is troubling. To address this problem, the aim of this study is to identify the pedagogical…

Public school teachers within a Pennsylvania intermediate unit are receiving inadequate job-embedded professional development that recognizes knowledge of content, pedagogy, and technology integration, as outlined by Mishra and Koehler's Technological Pedagogical Content Knowledge (TPACK) framework (2006). A school environment where teachers are…

This multiple case study investigated how teachers utilized C3 Framework-aligned instructional materials created with the Inquiry Design Model in unique contexts. Contextual factors related to how teachers enacted and experienced the C3 Framework were explored, in addition to how they planned, implemented, and assessed C3 Framework-aligned…

In order to teach about sustainability, teachers need to be able to translate their personal understanding of this concept into their pedagogy in ways that make it accessible to their learners. This translation process is known as pedagogical content knowledge (PCK). This study investigated the way that two teachers translated their understanding…

Technology integration is an important skill that teachers need to acquire to deepen students' learning and support achievement of instructional objectives. Selecting the best technology tool can be challenging however, teachers face more difficulties to effectively integrate technology into their classrooms. Providing one-time workshops is…

As emerging technology continues to enter the social studies classroom, teachers need to approach integration of such technology in a systematic manner to ensure that such technology enhances the learning of their students. Currently, scholars of technology integration advocate for the use of one of two different models, either SAMR or TPACK. This…

With the education systems demand of contemporary technologies, teacher trainees should be imparted with competencies and skills to integrate information and communication technology (ICT) into their future teaching and learning practices. This study assessed classroom ICTs integration opportunities and the challenges in relation to Technological…

The purpose of this study was to explain middle school teachers' decisions for planning a science unit of instruction (reflection on action) and their decisions when enacting this planned unit (reflection in action) using the new teacher professional knowledge and skill (TPK&S) model as a guiding framework. In addition, this study specifically…

The objective of this study is to demonstrate that the criteria of didactical suitability, proposed by the theoretical framework known as the Onto-Semiotic Approach (OSA) of mathematical knowledge and instruction, are powerful tools for organizing the reflection and assessment of instruction processes carried out by mathematics teachers. To this…
