To equip students with 21st-century skills, teachers must have both deep STEM content knowledge and the confidence to implement and teach appropriate STEM content. Many elementary teachers have inadequate STEM background knowledge, low confidence, and STEM self-efficacy for implementing STEM in the classroom; as a result, teachers' classroom…

Predictors of teacher effectiveness in relation to student achievement are based on the ability to use a range of evidence-based teaching strategies. Australia's Teacher Education Ministerial Advisory Group (TEMAG) report that some tertiary providers working with pre-service teachers (PSTs) are using pedagogical practices which are not informed by…

The aim of the study is to adapt the "Maker-Based Technological Pedagogical Content Knowledge" scale developed by Ku et al. (2021) for pre-service science teachers into Turkish. The study group for the research consists of 188 pre-service science teachers studying at the Department of Science Education at three state universities in…

In an effort to address K-8 teacher confidence in STEM and increase basic genetics knowledge to a level consistent with its importance in society, we have developed, implemented, and evaluated a 7-day teacher professional development workshop. The overarching goal of our workshop is to facilitate the implementation of innovative DNA-based…

This article advances a continuing line of inquiry into an innovative teacher-support program intended to help in-service history teachers develop professional teaching knowledge for inquiry-based history instruction. Two prior iterations informed our design and use of professional development materials; they also informed the implementation…

Background: The results of international studies have concluded the low level of science literacy in natural science subjects of Slovak students. These studies also showed that this state can be positively influenced by various innovations, which are implemented into the teaching process of above-mentioned subjects. Purpose: The aim of this study…

The purpose of this study is to explore the perceptions of trainees towards a professional development program. The target is to train teachers on how to use a learning management system called "Blackboard" for designing courses that could be taught online in the future.

In this study we measured changes in science teachers' conceptual science understanding (content knowledge) and pedagogical content knowledge (PCK) while participating in a problem-based learning (PBL) model of professional development. Teachers participated in a two-week long workshop followed by nine monthly meetings during one academic year…
