Teacher professional development (PD) is essential to continuously improve teaching skills, to adapt to diverse student needs, and to promote equity and inclusion. Only a few studies to date have synthesized how PD programs improve teachers' content knowledge and instructional quality, as well as students' academic performance. In this…

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…

Pedagogical content knowledge (PCK) is considered an important ingredient in shaping classroom practice. PCK requires valid measurement at domain-specific level on different components excluding the teaching context. While the research focuses on measuring the PCK of unqualified teachers and pre-service teachers, the description of qualified…

Knowledge of science content and the ability to translate knowledge into effective teaching is known as teachers' "content knowledge for teaching" (CKT). Teachers with developed CKT are able to more effectively determine instructional and assessment activities that will deepen K-12 students' scientific literacy. However, preservice…

Research attention to investigating elementary STEM teachers' Professional Learning Networks (PLNs) has grown. However, what types of Open Educational Resources (OER) and Technological, Pedagogical, and Content Knowledge (TPACK) elementary STEM teachers share in their PLNs are still under-examined. This case study aims to explore elementary STEM…

The study assessed, designed, developed, validated, implemented, and evaluated the effects of the e-training package on TPACK. The study was conducted at Bukidnon State University from 2021-2022. Using Research and Development, an e-training package on TPACK involved Content Knowledge, Technological Knowledge, and Pedagogical Content Knowledge was…

Creating awareness of environmental sustainability issues through formal education may be an effective way to help citizens deal with these issues. Teachers, however, have not been sufficiently trained on how to teach with sustainability concerns in mind. For this study, a purposively selected group of six chemistry teachers was exposed to an…

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…

A professional development intervention (PDI) was developed for science teachers, focusing on pedagogies to integrate indigenous knowledge (IK) into school curriculum topics. The study aimed to determine which characteristics of science PDIs were imperative to support teacher learning and influence teacher practice for IK integration in science…

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…

High school science teachers are a unique subset of teachers with distinctive PD needs in content, pedagogy, and technology, yet there is scant research about PD from the perspective of secondary science teachers. This qualitative research study used narrative research methods with grounded theory to explore how a group of seven high school…

This study examined the impact of the Indonesian pre-service teacher professional education program (PPG) on pre-service science teachers' technological pedagogical content knowledge (TPACK) competencies. As a government-directed initiative, the PPG program's curriculum is aligned with TPACK principles. We conducted a comparative analysis…

This study examines Chinese primary science teachers' professional learning experience in a web-based community of practice established and run by practitioners, with support from teacher researchers. Over time, it has grown into a preferred knowledge-sharing base for primary science teachers of the region and gradually gained national…

Reading, at its core, is a basic yet critical way to undertake learning and growth. This paper shares a professional learning and development initiative for science educators, which was underpinned by the popularity and premise of the reading group. In moving from simply being a vehicle for targeted discussion, the reading group facilitators…

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.…
