The main purpose of the study was to investigate the effect of Jigsaw-4 problem-solving instruction on preservice physics teachers' (PSPT) problem-solving skills in the college of teacher education in the Southern nation nationality region of Ethiopia. The study involves 136 first-year PSPTs who are attending their preservice teacher education…

This paper is about leveraging cultural ways of knowing such as ethnobotany in order to increase STEM engagement in Chicanx populations. The novel Community Learning and Ecological Sustainability Paradigm (CLESP) framework utilized in this study combines social justice, Chicana feminist epistemology, land-based pedagogy, critical place-based…

Background: Training both pre - and in-service teachers who are capable of planning and enacting engineering design-based science instruction are critical for integrating engineering into K-12 science curricula. Purpose: This study investigates pre-service teachers' efforts to integrate engineering into their lesson plans. Sample: 13 pre-service…

Understanding how racially and linguistically just teacher education programs (TEPs) support the identity(ies) and translanguaging stances taken up by bilingual Black, Indigenous, and People of Color (BIPOC) teacher candidates (TCs) in their professional lives is important both for their development as teachers and for teacher preparation more…

This investigation adjusted the lesson study (LS) model for the initial teacher education aiming to examine its effect in the development of the pre-service teachers' pedagogical content knowledge (PCK) namely, both their knowledge and understanding on how to transform a science topic to make it more understandable for the students. The LS topic…

Background: Science teacher education programs are considered to play a critical role in preparing future science teachers who are more innovative and capable of effectively implementing integrated STEM education. Purpose: This research investigates the effectiveness of a professional development program enriched by the skills-based science,…

A core element of teacherss' professional knowledge is their Pedagogical Content Knowledge (PCK). The Refined Consensus Model of PCK defines three realms of PCK: collective PCK, personal PCK and enacted PCK. ePCK encompasses the acts of planning and reflecting on a lesson. Digital simulations allow the training of transferring pPCK to ePCK in…

Physics teachers need diagnostic competence to effectively identify students' misconceptions, but studies have yet to sufficiently investigate how this competence can be advanced through various instructional strategies. In this study, we compared a problem-solving strategy against an example-based strategy in advancing diagnostic competence in…

The purpose of this study was to improve preservice chemistry teachers' understanding of surface tension by using guided-inquiry activities. Ten preservice chemistry teachers participated in this study. Data were collected with open-ended questions on the effect of molecular weight, branching, and temperature on surface tension before and after…

A new perspective on chemistry learning could be the optimal learning moment of view based on flow theory. Optimal learning moments (OLMs) that occur when students experience high levels of interest, challenge, and skill at the same time were investigated in this study. Participants of the study were 47 pre-service science teachers. Data were…

This study aims to examine the effect of the framework proposed for professional ethics courses in teacher education on the pre-service science teachers' analysis of cases involving ethical dilemmas. The research was designed as a case study. The study group was composed of nine (two males and seven females) pre-service science teachers.…

Research on teacher educators' professional learning has gained increasing interest within science education. Curriculum materials have been suggested as a means of supporting "teacher" learning for several decades but have not yet been examined as a potential tool for supporting the learning of "teacher educators." In this…

This study aimed at exploring the understanding of concept inventories for classroom assessment by physics tutors and pre-service teachers in selected diploma teachers' training colleges in Tanzania. The study employed a qualitative research approach and a case study design. Eight physics tutors and 20 second-year pre-service physics teachers from…

Practical work is widely seen as an integral part of school science. Research and teacher guidance have tended to consider practical work in science, rather than in individual science subjects or topics. This study used a questionnaire of selected- and open-response items to probe the views and reasoning of a sample of 43 pre-service teachers in…

Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory…
