Pedagogical content knowledge (PCK) refers to the content-specific knowledge that teachers use to promote students' learning of specific subject matter. PCK comprises multiple knowledge components that interact with each other when enacted in teachers' instructional practices. For many years, researchers lacked a robust methodological approach to…

This paper investigated the integration of a Lesson Study Model (LSM) into distance STEM education during the COVID-19 pandemic. The study focused on six dimensions: (1) STEM education in distance learning, (2) Lesson Study (LS), (3) lesson planning processes, (4) challenges of lesson planning, (5) evaluation and assessment methods, and (6)…

As educational accountability pressures and science teacher attrition rates within American public-school systems continue to rise, so does the need for improved reform-based professional development (PD) opportunities that allow science educators to challenge their pedagogical beliefs and teaching practices. This qualitative case study explores…

Learning to plan modeling-based investigations (MBIs) presents significant challenges for pre-service elementary teachers. Although they understand disciplinary core ideas and modeling practices, they address both as competing learning goals and, as novices, they have not experienced how to structure MBIs for their future students. In the context…

Many theoretical models of action research depict its process as cycles that include several sequential phases. In Bhutan, teachers use Kemmis and McTaggart's spiral model which has four phases of: "plan," "act," "observe" and "reflect" to conduct action research for their professional learning. As a growing…

The purpose of this longitudinal study was to explore the development of pre-service chemistry teachers' pedagogical content knowledge regarding the effect of temperature on reaction rate topic as they took pedagogical content knowledge courses throughout the teacher education program. Pre-service teachers' pedagogical content knowledge was…

Many professional development programs aim to improve student outcomes by enhancing teacher competencies. Effective evaluation of these programs requires a clear delineation of the competencies to be gained. A competency model was developed to evaluate the impact of a teacher professional program that aimed to improve teachers' ability to…

The science teacher education community plays a prominent role in teacher preparation programs. Particularly, science methods courses emphasize modeling instructional strategies to promote inquiry-based practices. Integrating appropriate educational technology to enhance and support classroom practices should be embedded in these courses. The…

This study aims to evaluate the STEM SOS model based on the opinions of pre-service science teachers. For this aim, the contributions and the challenges of the STEM SOS model to pre-service science teachers were investigated. The participants consisted of 23 pre-service science teachers studying in the 4th grade of science teaching at a state…

Action research has gained widespread recognition as a tool to improve teaching practices in many countries, and action research based on Kemmis and McTaggart's model was recently introduced in Bhutan to raise teaching quality. This study explored how Bhutanese secondary science teachers carried out the process of action research and the factors…

The paper examines how science teachers' instructional adaptations to Toulmin's Argumentation Pattern (TAP), made during the first time the framework is introduced to students as a learning heuristic for structuring their arguments, could contribute to the way the quality of students' arguments is evaluated. We first depict these adaptations, that…

Global climate change (GCC) presents unprecedented global concerns, notably food supply limitations, unsustainable use of natural resources, and widespread environmental degradation. The International Panel on Climate Change (IPCC) reports a 0.85 °C increase in global average temperatures between 1880 and 2018 and a 50% increase in global carbon…

The aim of this study was to determine the effect of model-based cooperative (Reading Writing Application) and individual learning methods on conceptual understandings of pre-service science teachers and to eliminate their misconceptions related to gases. For this reason, a pretest/post-test non-equivalent comparison group design was applied…

This study explored teachers' conceptualizations of integrated computational modeling in secondary physics by exposing twelve experienced physics teachers to programming and then analyzing interview responses. Responses revealed that teachers fell along a spectrum of disciplinary boundary-stretching mentalities. This paper presents a preliminary…

Systems thinking in chemistry education (STICE) has been proposed as an approach that could better equip students with abilities to connect their chemistry knowledge with other disciplines and with the skills needed to tackle complex global issues. However, educational change in chemistry is a complex effort that involves many interconnected…
