This paper presents Irish-medium immersion (IMI) teachers' perceptions of their development of content knowledge of language (CK-L) and pedagogical content knowledge of language (PCK-L) as a result of engaging in form-focused professional development (PD) which combined both content knowledge and pedagogical learning outcomes. An intervention,…

K-12 students with disabilities in the United States are increasingly enrolling in online schools and educational programs. Therefore, K-12 online public and charter school special education (SpecEd) teachers must be prepared to develop and implement individualized educational plans (IEPs) that meet the procedural and substantive requirements of…

This dataset was collected for the fulfillment of the first author's PhD studies. It was collected in two phases. Preliminary data investigated the status of tutors' mathematical knowledge for teaching. A lesson planning intervention framed within the technological and pedagogical content knowledge framework was provided to an experimental group…

The nature of knowledge and how it is developed have been debated in philosophy and research for centuries. In the literature on teachers' knowledge, two perspectives have been particularly visible. One perspective stresses cognitive processes and deliberate knowledge acquisition. Another perspective stresses the situated nature of teachers'…

Research indicates that a large percentage of students have misconceptions of the equal sign and that this can be detrimental to their mathematical pursuits as they progress through algebra. In order for students to develop a strong understanding of the meaning of the equal sign, algebra teachers must be aware of the viewpoints their students will…

Schools are increasingly adopting universal social-emotional learning (SEL) programs to support students' prosocial development and academic success. When adopted across contexts and student populations, SEL interventions can be implemented in different ways particularly under typical classroom conditions that are not part of research efficacy…

Research into teachers' epistemic cognition is emerging as a key to understanding the quality of teachers' knowledge for teaching. Typically, investigations into the quality of teachers' knowledge have been situated within traditional subject areas, such as science or maths. However, developing good quality teacher knowledge about improving…

Dual language and immersion (DLI) instruction at the secondary level is a particular challenge, as teachers are tasked with teaching abstract, cognitively complex content while supporting students in continuing to develop their partner language proficiency. This content and language integration requires a unique skill set and knowledge base, but…

This article advances a continuing line of inquiry into an innovative teacher-support program intended to help in-service history teachers develop professional teaching knowledge for inquiry-based history instruction. Two prior iterations informed our design and use of professional development materials; they also informed the implementation…

In this paper, three elements of primary pre-service teachers' relationships with mathematics are explored: mathematical achievement, feelings about the subject, and confidence to teach mathematics. At the beginning of their programme, under half of the pre-service teachers did not meet the numeracy requirements and took part in a support…

Global climate change, referred to as climate change in this paper, has become an important planetary issue, and given that K-12 students have numerous alternative conceptions or lack of prior knowledge, it is critical that teachers have an understanding of the fundamental science underlying climate change. Teachers need to understand the natural…

One of the major outcomes from the national Teaching Teachers for the Future (TTF) Project in 2011 was the development and statistical validation of a survey instrument to measure the Technological Pedagogical Content Knowledge (TPACK) of pre-service teachers as a result of the TTF intervention implemented across all Australian Education…

Against the background of concerns around teaching and learning outcomes in primary school mathematics in South Africa, this article presents two studies conducted in American Samoa and seeks to draw implications for the teaching and learning of mathematics in South Africa. American Samoa has a very similar educational context to South Africa. The…

Professional development--formal in-service training to upgrade the content knowledge and pedagogical skills of teachers--is widely viewed as an important means of improving teaching and learning. While many interventions "include" professional development, professional development was the central intervention of the two recent research and…

The effect of a 15- to 24-month in-service professional development (PD) program on state accountability mathematics test scores for middle school students was examined using a quasi-experimental design. Middle level mathematics teachers (n = 128) from 7 school districts and 64 middle schools volunteered for a PD sequence of content-oriented…
