The purpose of the study was to determine the perceptions, knowledge levels, and mental models of gifted 2nd and 3rd-grade elementary students regarding the shape of the Earth and gravity concepts. The data for the study, which was qualitative research, was collected through interviews with the students. The study participants were 80 students…

Over the years, there have been various calls to increase and better represent astronomy in curricula. This is motivated by views within the astronomy and astronomy education communities that the awe, wonder, and interdisciplinary nature of astronomy has the potential to engage students in STEM across disciplines. Reviews of curricula have shown…

To support the development of more robust conceptual knowledge, it is crucial to understand the alternative conceptions that students bring to the classroom, and how these can be considered and dealt with through instruction. In this study, we report the alternative conceptions of 498 students enrolled in secondary education in Ireland. A…

Student-generated questions and ideas about our universe are the start of a rich and highly motivating learning environment. Using their curiosity-driven questions and ideas, students form Knowledge Building groups or "communities" where they plan, set goals, design questions for research, and assess the progress of their work, tasks…

Effective faculty professional development must be participant centered; tailored to the needs and interests of the faculty who engage in it. In order to better understand those needs and interests, we investigate how knowledge, attitudes, beliefs, and teaching practice vary among new physics faculty, using surveys of a large sample (n = 442) of…

This paper presents an analysis of physics teachers' as well as university and high school students' understanding of some astronomy concepts. In recent years, the significance of astronomy teaching in science education has gradually increased. Many research studies indicate that students have misconceptions about the reasons for seasons, the…

While there has been a remarkable worldwide convergence in the emphases of primary science curricula over the last four decades, the cognitive and knowledge demands that they make on learners have not been well-researched. Without knowing what these intellectual or epistemic requirements are when learning science in school, issues concerning…

This paper examines the knowledge construction processes involved when grades 7 and 8 South African students learnt about the concept of gravity while visiting an astronomy-related science centre. The literature on students' understanding of gravity identifies a number of alternative conceptions prevalent, several of which are mirrored in this…

In order to improve instruction in introductory astronomy, we are investigating students' preinstructional ideas about a number of cosmology topics. This article describes one aspect of this large research study in which 1270 students responded to a subset of three questions each from a larger set of questions about the following areas: definition…

The purpose of this study was twofold. First, it was aimed to identify Turkish pre-service physics teachers' knowledge and understanding of the Moon, Moon phases, and other lunar phenomena. Second, the effects of model-based teaching on pre-service teachers' conceptions were examined. Conceptions were proposed as mental models in this study. Four…
