Teachers are increasingly expected to incorporate Project-based learning (PBL) pedagogy to teach science. While teachers' definitions and challenges in the use of PBL are widely studied, very few studies focus on the development of a teacher's knowledge of the use of PBL over multiple projects. The current research is an in-depth case study aimed…

Research about modeling emphasizes the importance of heterogeneity in science learning. At the same time, a growing body of scholarship seeks curricular pathways for epistemic and representational convergence. In response to this tension, we propose two constructs: heterogeneity-seeking curricula and commitments. Heterogeneity-seeking curricula…

The aim of this study is to reveal experienced primary school teachers' pedagogical content knowledge (PCK), sub-components of PCK, and their possible interactions with science teaching. To this aim, a multiple holistic case study design was used. The research used a comprehensive PCK model consisting of 5 categories and 28 subcategories to…

Young children's instinctive curiosity is essential in early childhood science education. Efficacious science education is associated with the characteristics of a qualified science program and an effective learning environment. The out-of-school learning environments make it easier to achieve the aims of science education in early childhood with…

Inquiry-based science instruction has been proposed as an optimal learning environment for language-integrated teaching. While its potential for developing both content knowledge and language skills has been shown for students with limited language proficiency, research focusing on mainstream classrooms has mainly considered domain-specific…

The aim of this research is to determine the misconceptions of students about the subject of the moon and to examine the effects of science lesson with reflective science diaries on the achievements of students and eliminating their misconceptions. The research designed according to the pretest-posttest control group model among the experimental…

Throughout the country, there are many bodies of fresh water affected by algal blooms. By focusing on a water source near their school, students can become scientists, too. Situating science content in real and meaningful learning experiences encourages students to be invested in their own learning, construct deeper understandings, and apply those…

The climate emergency is a source of anxiety for many young people. Images of drought, heat waves, wildfires, storms and flooding are increasingly appearing in the media. Today's children stand to be the recipients of our legacy of climate change, while not feeling empowered to do anything about it, so perhaps it is no wonder they are anxious.…

The science curriculum aims to provide students with the identity of a researcher, thinking skills, and scientific process skills. Critical thinking skill emerges as one of the skills that should be emphasized in the teaching process in terms of its structural features and the qualities aimed to be given to individuals. For individuals to gain…

This study aimed to explore what kinds of epistemological messages were conveyed through teacher discourse in modeling-based and traditional elementary science classrooms and how teachers framed the two classrooms distinctively through these messages. Data came from two sixth-grade teachers' science classrooms--one characterized as a…

Space telescopes are some of the most precise and complicated machines ever built. Not only must they survive the harshness of space travel, but they also need to be incredibly accurate: misalignments by fractions of a millimetre can have huge effects on the quality of the images they capture. In 1990, the Hubble Space Telescope became the first…

Integrated science-and-literacy programs have proven to positively affect both language proficiency and science knowledge. Because making connections is important in both text comprehension and understanding the disciplinary core ideas taught in science, it seems worthwhile to explore the potential of integrating text structure instruction in…

Equitable sensemaking allows for meaningful understanding of the big ideas of science and deeper engagement in science practices. Many nonscience majors, including elementary preservice teachers (PSTs), do not have opportunities to engage in equitable sensemaking within their secondary or college-level courses. An innovative cycle to support…

This longitudinal study examines the relationship between students' knowledge-in-use performance and their performance on third-party designed summative tests within a coherent and equitable learning environment. Focusing on third-grade students across three consecutive project-based learning (PBL) units aligned with the Next Generation Science…

Including systems thinking in science education helps students understand the complex global problems of the present era. The study aimed to trace and evaluate the system thinking (ST) skills in K-8 science curricula, with a focus on sustainability-related subjects and units. Firstly, the authors reviewed the related literature on the systems…
