Aim of this study was to examine the end-of-unit evaluation questions in the 6th Grade Science book of primary education according to the knowledge and cognitive process dimensions of the Revised Bloom Taxonomy. For that purpose, 130 end-of-unit evaluation questions of 6th grade Science textbooks which were approved by the Board of Education and…

While traditional teaching methods such as face-to-face lectures, training, and mentoring have been utilised in the educational process, the importance of websupported materials was better underscored with the advent of the pandemic. Documentary videos, prepared with scientific data, serve as significant web-supported materials. The aim of this…

The COVID-19 pandemic imposed profound changes on the way we think about undergraduate physics education. Online courses became mainstream. Exam formats were reimagined. Digital whiteboards replaced face-to-face discussions. Laboratory classes were outfitted with home-delivered supply kits. And all of us developed a more intimate knowledge of…

This paper reports a mapping of the astronomy content knowledge held by a sample of 171 Chilean in-service teachers, both from primary and secondary education, using a multiple-choice test. The responses were analysed by total achievement, and the proportion of alternative conceptions for each item was identified. Moreover, the test items were…

From ancient times, the different features of planets and moons have created a huge interest. Aristarchus was one of the first to study the relative relations among Earth, Moon, and Sun. This interest has remained until today, and therefore it is always relevant to make this knowledge more appealing to the younger generations. Nowadays, smartphone…

In recent years, general relativity (GR) and gravitational-wave astronomy have emerged both as active fields of research and as popular topics in physics classrooms. Teachers can choose from an increasing number of modern instructional models to introduce students to relativistic ideas. However, the true potential of an instructional model can…

Two well-regarded measurements for the expansion rate of the universe disagree, leaving cosmologists very puzzled. It may be that something large has been overlooked in our theory of the Big Bang. This discrepancy is called the Hubble tension and it has led to a very interesting conversation within the cosmology community.

Research Findings: Grounded on personification storytelling, this intervention study introduced a science program including extensive astronomy concepts to 24 children (4-5 years). The storytelling attributes personal characteristics to cosmic bodies with metaphors relating to children's lives in explaining the scientific concepts, for example,…

A practical experiment is described to estimate the distance to a star using simple equipment, suitable for secondary or undergraduate students. The brightness of the star is visually matched to a miniature filament lamp, and its distance inferred from the inverse square law. Students gain an appreciation of astronomical units and practice in…

Collaboration is often emphasized as one of the key twenty-first century competencies to promote scientific literacies through many representational modes. However, collaborative interactions have been often characterized as a coordinated, synchronous, and symmetrical activity in terms of the same level of knowledge with little attention paid…

The Earth's shape concept develops as consecutive cognitive problems (e.g., the location of people and trees on the spherical Earth) are gradually resolved. Establishing the order of problem solving may be important for the organisation of teaching situations. This study attempted to determine the sequence of problems to be resolved based on tasks…

This research with middle school students from Kentucky (KY) and Nevada (NV) provides a snapshot of students' spatial-scientific understandings as we explored how well students understand lunar-related content, both spatially and scientifically, after receiving instruction with similar curricular Earth-Space content. Utilizing a lens of spatial…

In this study, it is aimed to examine the effect of augmented reality application on preschool children's knowledge of space. A mixed method, which combines both quantitative and qualitative methods, was used in the study. The study group consists of 24 children aged 60-72 months. In the study, a 10-question form created in line with the opinions…

This study aimed to elucidate the perceptions and mental models of 5th-grade secondary school pupils about shadows, solar eclipses and lunar eclipses through drawings. A total of 443 pupils studying at public schools in Afyonkarahisar participated in the study. It was conducted as a case study, one of the qualitative research designs. As a data…

This study aimed to examine the opinions of the instructors who work at GUHEM (Gökmen Space and Aviation Training Center) on the exhibition's content, how the exhibition spaces contribute to science education, especially astronomy and aviation, and the types of visitors who frequently visit the center. Nine instructors from GUHEM's science centers…
