Mathematical knowledge for teaching (MKT) is a professional knowledge crucial for effective mathematics instruction, encompassing both content knowledge (CK) and pedagogical content knowledge (PCK). The purpose of this study is to investigate the hierarchical structure of PCK for fractions by seeking further evidence for the PCK-Fractions…

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,…

Since 1997, Mexico - like many Latin American countries - has seen significant public and private investment aimed at incorporating information technology in the classroom. In-class information technology holds the great promise of revolutionizing the teaching-learning process. The reality is different, often showing negligible impact from such…

Data from a large-scale math intervention program were used to evaluate the degree to which implementation fidelity (IF) and interventionist content knowledge were associated with student outcomes. Data were available for 33 interventionists serving 658 students in Grades 4-6 across one school year. A series of multilevel models were fit to the…

Although widely touted as important, there is little evidence regarding the influence of teaching experience on elementary teachers' science subject matter knowledge (SMK). To better understand this phenomenon, we administered an assessment of science topics taught in the fifth and sixth grades to 169 preservice teachers, 231 fifth-grade teachers,…

National standards and frameworks for mathematics, computer science, and technology emphasize the importance of teaching all children computational thinking (CT) skills. These skills are important for preparing citizens that are literate in science, technology, engineering, and mathematics and for participation in a society that is rapidly…

Educators and the public often assume that digital technologies lay within the domain of newer teachers who may have grown up in a more digital world or have more practical experience using different mediums of technology, like social media and Web 2.0 applications. However veteran teachers have strong content and pedagogical knowledge at their…

Statistics is an increasingly important component of the mathematics curriculum. "StatSmart" was a project intended to influence middle-years students' learning outcomes in statistics through the provision of appropriate professional learning opportunities and technology to teachers. Participating students in grade 5/6 to grade 9…

A strategy-based reading promotion program was implemented over a course of 8 months in 65 classes from grades 5 to 7 (student age M?=?11.2 years, SD?=?1.0). It was investigated whether teachers flexibly adapted their pedagogical content beliefs (PCBs) on the teaching of reading according to the instructional principles of the intervention.…

The purpose of this qualitative study was to examine what effective teaching with technology looked like in practice within middle grade Social Studies' classrooms. An additional purpose was to understand how teachers' combine content knowledge, pedagogical knowledge, and technological knowledge when making decisions about their curriculum.…

Despite a general consensus on the educational effectiveness of inquiry-based instruction, the enacted type of inquiry in science classrooms remains debatable in many countries including Saudi Arabia. This study compared guided-inquiry based teachers' professional development to teacher-directed approach in supporting Saudi students to understand…

The purpose of this report is to explore the content-related validity evidence supporting the English language arts (ELA) components of the "ETS"® National Observational Teaching Exam (NOTE) assessment series, a kindergarten through 6th-grade teacher licensure assessment. To establish the content knowledge required for the effective…

A critical incident is a situation or event that holds significance for learning, both for the students and teachers. This paper presents four examples of critical incidents from a Year 7 teacher's lesson excerpts in Indonesia involving teaching of fractions, to show how they shaped classroom situation, brought forward elements of conflict, and…

This study investigates, through an experimental design, the effectiveness of a professional development program on teacher knowledge and practices and on student learning. The program consisted of a series of video-based modules designed to respond to needs of U.S. teachers, as highlighted by findings from the 1999 Third International Mathematics…

The purpose of this report is to explore the content-related validity evidence supporting the mathematics components of the "ETS"® National Observational Teaching Exam (NOTE) assessment series, a kindergarten through 6th grade teacher licensure assessment. To establish the content knowledge required for the effective teaching of…
