The purpose of this study was to conceptualize a pedagogical content knowledge framework for informal science educators (ISE-PCK). An initial, hypothetical framework was created grounded in the literature in informal science education (ISE) as analogous to PCK models in formal science education. An exploratory sequential mixed-methods research…

This paper examines professional growth of a STEM teacher from the entrepreneurial frame. Using a personal narrative together with a STEM/science lesson package developed by the participant teacher, we unpack a teacher's professional growth by interpreting her beliefs and actions using characteristics of entrepreneurial thinking. Our analysis and…

Mechanistic explanations, aiming to disclose details of entities and their activities, employ the act of unpacking which, inherently and paradoxically, produces explanatory gaps--pieces of undisclosed, undetailed mechanistic information. These gaps, termed explanatory black boxes, are often perceived as counterproductive to the teaching of…

This article utilizes a framework for classifying different scientific methods suggested by a philosopher of science (Brandon "Synthese," 99, 59-73, 1994) called Brandon's Matrix. It presents findings from teachers who took part in a funded project in England that looked at the nature of scientific methods in science investigations.…

STEM education is present in most recent curriculum reforms around the world. One of the main novelties of this educational movement is the integration of engineering practices into science education. In the Spanish educational context, this implies an important challenge for science teachers. So, this study analyzes whether secondary science…

Teachers' development can be seen as a dialog between their reflective thinking and their actions, with an added gradient of complexity from their social interactions. All of these elements are conjugated within their classroom practice, with their Pedagogical Content Knowledge (PCK) as theoretical background. This paper analyzes the case of a…

This paper reports a pretest-posttest study about the impact of a teacher professional development (TPD) programme on primary school teachers' knowledge of and attitude towards inquiry-based learning. A pedagogical framework of inquiry phases and domains of scientific knowledge combined with hard and soft scaffolds formed the basis for the TPD…

This paper reports an empirical study of teacher development in the process of implementing an integrated science curriculum in a junior high school in China. Six science teachers with different subject backgrounds were invited to participate in this study. A pragmatic model of teacher learning that includes both cognitive and situated-learning…

Teaching experience has been identified as an important factor in pedagogical content knowledge (PCK) development. However, little is known about "how" experienced teachers may draw on their previous experience to facilitate their PCK development. This study examined how two experienced high school biology teachers approached the…

The nature of science (NOS) has become a central goal of science education in many countries. This study refers to a "developmental work research" program, in which four fifth-grade elementary in-service teachers participated. It aimed to improve their understandings of NOS and their abilities to teach it effectively to their students.…

In 2013, as part of a process to renew an overall sector vision for science education, Catholic Education Melbourne (CEM) undertook a review of its existing teacher in-service professional development programs in science. This review led to some data analysis being conducted in relation to two of these programs where participant teachers were…

Learners of English as a new language and the teachers who find these young people in their classrooms face many challenges. For secondary science educators, this is often rooted in a general lack of professional development models for the design and implementation of science/language integrated instruction. To address this issue, the present…

Experienced teachers possess a unique teaching knowledge comprised of an inter-related set of knowledge and beliefs that gives direction and justification to a teacher's actions. This study examined the expansion of two components of pedagogical content knowledge (PCK) of three in-service teachers in the course of a professional development…

Inquiry- and context-based teaching strategies have been proven to stimulate and motivate students' interests in learning science. In this study, 12 teachers reflected on these strategies after using them in primary schools. The teachers participated in a continuous professional development (CPD) programme. During the programme, they were also…

The paper describes characteristics and analyses difficulties of environmental sciences teachers in mentoring their students in an extended inquiry project, which is a mandatory requirement of the environmental sciences matriculation in Israel. The teachers participated in a professional development program that provided both content knowledge and…
