This study sought to narrate the experiences of a digital novice South African rural teacher, using technological pedagogical reasoning (TPR). The ubiquity and pervasiveness of digital technology is creating a need for teachers to develop TPR to remain relevant in this ever-changing global teaching community. TPR is developed in the real context…

The purpose of this study was to improve the pedagogical content knowledge (PCK) of pre-service chemistry teachers using a school experience course enriched with PCK development tools such as CoRe as a lesson planning form, observations of mentor teachers' teaching by using an observation form prepared based on PCK components, discussion sessions…

This study focused on middle school science teachers' experiences in using technological tools to teach scientific inquiry skills in the middle school science classroom. Technological tools have been increasingly used in middle schools, but knowledge is lacking as to which tools are efficient in teaching scientific inquiry skills. The purpose of…

With the rapid emergence of educational technology in learning environments, instructors' development of technology knowledge is necessary to select educational technologies for effective instruction. Online courses have also shown steady growth in higher education institutions over the past two decades. More recently, the rapid shift to online…

A key process in the discipline of science is argumentation, which has recently been receiving more attention in K-12 classrooms. The purpose of this multiple case study was to concurrently examine self-regulated learning processes (SRL) and learning outcomes of three teachers in a professional development (PD) on argumentation in science to…

Chemistry graduate teaching assistants (GTAs) play a unique but important role in undergraduate STEM education. As leaders of laboratory and discussion sections, GTAs teach fundamental experimental techniques and reinforce course content in classrooms and have more opportunities to interact with students one-on-one or in small groups. GTAs often…

Learning to teach out-of-field is a challenge that many teachers worldwide face at some time in their career. Whether they are motivated to seek formal professional development as additional qualifications in this area, however, depends on many factors. Alignment between the specific professional development needs of out-of-field teachers and the…

Collaboration between teachers and academics can have a sustainable impact on teachers' professional development. Accordingly, the aim of the study was to investigate the effect of the academic counseling model (ACM) based on academic-teacher collaboration on the pedagogical content knowledge (PCK) of in-service teachers. The ACM consists of five…

Professional knowledge for science teaching develops over time and interplays with professional experiences in field. In the present study, we explore student teachers' reflective conversation upon teaching experiences, with pedagogical content knowledge, PCK, as an analytical lens. The empirical data is based on nine meetings, with groups of 3-6…

In the last decade different instruments were developed to empirically test the TPACK theoretical framework. The TPACK for Meaningful Learning survey was the first survey to obtain statistical validation for all seven predicted constructs. In the present work we used a version of the TPACK for Meaningful Learning survey adapted and validated in…

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,…

There is growing recognition of the prevalence of "within school churn", a phenomenon in which teachers remain within a school but are assigned a new grade level or course. In this study we examine the consequences of within-school churn for the pedagogical content knowledge of elementary teacher participants in an NSF-funded science PD…

There is limited evidence of guidelines for planning for teaching at the higher education level either in the research literature or in higher education institutions themselves. As a result, novice lecturers struggle to plan for their teaching. The purpose of this study was to explore how planning can be done at a higher education institution by…

Interdisciplinary science teaching is an issue in various countries. One example in Europe is Germany, especially regarding comprehensive schools. At the same time, German teacher education is primarily subject-specific. An examination of data on self-efficacy beliefs is helpful for understanding the qualifications of teachers for…

This study took place within an environment of educational change in teaching and assessment in the UK, where the National Curriculum (NC) and National External Examination syllabi undertook significant revision. Science education specifically, has seen aspiration raised to allow pupils to achieve a greater depth of understanding at Key Stage 4…
