Lara Rodrigues; Stephen M. Pompea; Alejandra Meneses; Maximiliano Montenegro – Journal of Science Teacher Education, 2025
Chile is home to most of the world's largest telescopes, and astronomy research is robust in the country. However, astronomy education in Chile is much less mature. As an effort to increase its quality and coverage, more astronomy K-12 teacher professional development (PD) has been offered in Chile in the last decade, but the results of these…

Allan Feldman; Nadja Belova; Ingo Eilks; Marika Kapanadze; Franz Rauch; Rachel Mamlok-Naaman; Mehmet Fatih Tasar – Journal of Science Teacher Education, 2025
Action research (AR) has long been promoted as a way teachers can improve their practice and increase their understanding of their educational situations. In this article we examine the impact of AR on science teacher education through a critical review of the literature. We sought to identify the goals and purposes of the AR, its mode, and the…

Jiafa Wu; Ying Wu; Shaobin Gu – Biochemistry and Molecular Biology Education, 2024
This study identified a lackluster classroom atmosphere in advanced biochemistry, characterized by low levels of active student participation in interactive communication and subpar quality of after-class learning tasks. The issues stemmed not only from students' learning attitudes, such as insufficient attention to the curriculum, but also from…

Katarína Kotuláková; Lubica Janošcová; Natália Priškinová; Katerina Trcková – Journal of Science Teacher Education, 2024
The purpose of "practical work" in chemistry lessons as perceived by teachers varies and does not always correspond with an emphasis on procedural learning. Teachers project various objectives in them. These activities have various characteristics and potential. The goal of this study is to find out the set of characteristics of…

Pascal Kaneza; Jean Baptiste Nkurunziza; Innocent Twagilimana; Thumah Mapulanga; Anthony Bwalya – Cogent Education, 2024
This study aimed to examine the effect of three teaching approaches: The traditional teaching method, Teacher based demonstration experiment (TBDE), and the Student hands-on experiment (SHE), on students' conceptual understanding of solutions and titration. The data were collected using a chemistry achievement test (CAT) comprising of 30…

Pei-Ling Hsu – International Journal of Science Education, Part B: Communication and Public Engagement, 2024
With the rapidly increasing demand for STEM skills, many scientists, mathematicians, engineers, and technology professionals encourage students to pursue STEM careers. However, communicating science to lay audiences is challenging due to complex scientific terminology. This qualitative research aimed to demonstrate how an exemplary scientist, Dr.…

Rinalyn G. Magtibay; Rebecca C. Nueva España – Journal of Practical Studies in Education, 2024
The study aims to design a socio-scientific issues (SSIs)-based electronic learning (e-LM) design framework. It is anchored to the SSI occurrences in teaching Science at a State University in Batangas province, Philippines. This SSI-based e-LM design framework will guide the e-LM development for teaching Science socio-contextually through flexible…

Merve Ozkizilcik; Umran Betul Cebesoy – International Journal of Technology and Design Education, 2024
National reform documents all around the world issue an urgent need for the development of integrated STEM (Science, Technology, Engineering, and Mathematics) curricula. With the emphasis on the development of STEM curricula, there is also a need for improving teachers' and future teachers' conceptions of the integrated STEM approach. This study…

Marie-Jetta den Otter; Alma Kuijpers; Michiel Dam; Ludo Juurlink; Fred Janssen – Research in Science Education, 2024
Chemical reasoning, and in particular structure--property reasoning, is an important goal of chemistry education. Johnstone's triangle (1982, 1991) is often used to explicate this type of reasoning. This triangle describes the multilevel thought chemical reasoning requires and shows why students find chemistry so difficult. However, this model…

Eric Hirsch; Sam Shaw – State Education Standard, 2024
More than a decade ago, the K-12 Framework for Education and the Next Generation Science Standards (NGSS) shifted states' notions of what constitutes the core of science skills and knowledge that students need to thrive in school and beyond. The majority of states adopted standards based on the framework as well as the NGSS. Yet because of the…
