This paper examines the praxeology of informal educational practices (i.e. how participants produce setting-specific practices to make a tour happen) in the Geophysical and Astronomical Observatory of the University of Coimbra through close analysis of a video-recorded excerpt of a guided tour. Guided visits in informal science settings are…

This study aims to examine preschool teachers' earth and space science practices and the expected achievements of children in these practices. The research was conducted with a phenomenological pattern. Participants of the study consisted of 28 preschool teachers working in public schools and determined by the criterion sampling method, one of the…

The epistemic components of science are included in instruction through the three-dimensional learning of the Next Generation Science Standards (NGSS). Students use the Science & Engineering Practices to engage the Disciplinary Core Ideas through the perspective of the Crosscutting Concepts. The NGSS focus on the epistemic aspects that all…

The aim of this research is to take a fresh look at the physical science concepts that Year 3 students struggle with. In this work, the responses of over 8,000 middle-primary-aged students to a range of physics, space science and chemistry questions were evaluated. The questions covered a number of topics ranging from selecting and using simple…

Astronomy education is essential for STEM education in primary schools, and integrating engineering design-based science education enhances student engagement and achievement in the field of space science. Integrating engineering design into science education is essential for students to excel in astronomy and to meet the requirements of…

What to say to the public about asteroid hazards and how to say it to them? In this article, we relate how our small professional research institution (Klet Observatory, Czech Republic), devoted specifically to Near-Earth Objects (NEOs), together with the educational branch (Ceske Budejovice Observatory and Planetarium, Czech Republic), has…

This paper presents strength and thermal studies, as well as an analysis of the design material for the development of a nanosatellite model. By using the SolidWorks software environment, an effective solid-state finite-element model of a nanosatellite are developed, on the basis of which the stress-strain state of the nanosatellite is analyzed,…

As part of a multiyear research project investigating the affordances of online citizen science (OCS) projects for enhancing school students' learning in relation to science and digital technology, teacher-researchers have designed and implemented classroom interventions incorporating one or more OCS projects. The project is situated in New…

The aim of this study is to comparatively investigate the effects of hands-on models (HMs) and computer simulations (CSs) on teaching the phases and eclipses of the Moon. In this study, two different HMs were developed, and three different CSs were used. The research work group consisted of 100 pre-service science teachers. A quasi-experimental…

Research has shown that hands-on projects promote stem education, namely via problem-solving. CanSat, literally 'satellite in a can', is a stem educational project promoted by the European Space Agency. This paper addresses this issue by researching this STEM project and trying to understand how secondary students solve problems in the STEM CanSat…

Field trip activities are often considered additional activities and are considered recreational activities rather than ones that teach science effectively to students. Field trip activities are one form of effective experience-based learning to train pre-service teachers in the outdoor environment. This study attempted to describe the design of…

Similar to how stealth materials were developed to reduce the radar wave energy returning from an aircraft, here we explore a low-cost laboratory demonstration that uses similar principles to prevent detection of an object by an ultrasonic sensor. This demonstration setup can be used as a starting point to encourage students to explore the surface…

A conceptual framework for empirical research on the impact of NASA Space Science Education Consortium (NSSEC) activities is presented in this paper, along with a cross-referencing system between the NSF-based NSSEC evaluation framework and historical definitions of comparable psychometric constructs in the literature. A selected set of findings…

Students' declining performance in science and mathematics is an issue of great international concern. Recently, educators and researchers have begun to focus on affective factors such as interest to better understand STEM learning and persistence. Therefore, there is a need for effective measures of STEM interest that allow it to be tracked over…

A large body of work has shown that science teacher knowledge is one of the most fundamental components of effective teaching and learning. Our study analyzes the Praxis® Earth and Space Science Content Knowledge Test (ESS CKT) from May 2006 to June 2016. We present one of the largest datasets comprising 11,273 ESS teacher candidates in order to…
