My childhood experience in school was fragmented from my out of school experience where I lived in rural China. School subject matters were reduced to bits and pieces. I excelled in this artificial symbolic world. Progressing from preschool to graduate school, I trained to teach in that world, and gained the opportunity to study at Harvard. My…

Science curriculums and curricular materials are essential guidelines in materializing effective science teaching. The primary goal of the current study aims to present a thematic analysis of the last three elementary and middle school science curriculums objectives released in 2013, 2017, and 2018 to determine whether they provide a base for…

This research aimed to investigate animation-based achievement tests according to the item format, psychometric features, students' performance, and gender. The study sample consisted of 52 fifth-grade students in Samsun/Turkey in 2017-2018. Measures of the research were open-ended (OE), animation-based open-ended (AOE), multiple-choice (MC), and…

Using innovative technologies to study Mars and the sun and other stars is one way to engage learners in learning more about our solar system and how it impacts us on a daily basis. The focus of this paper is to highlight several innovative technologies such as augmented reality and virtual reality that are easily accessible by educators and…

This article presents a qualitative study of the type and quality of questions formulated by prospective elementary teachers (PETs) when designing scientific inquiry activities, depending on the school science content selected. The data were acquired during teacher training instruction on these aspects with 67 participant PETs. The results showed…

Teaching cosmology at the undergraduate or high school level requires simplifications and analogies, and inevitably brings the teacher into contact with at least one of the pedagogical interpretations of the expanding Universe. The by far most popular interpretation holds that galaxies in an expanding Universe are stationary, while space itself…

This research compared the process of disciplinary literacy acquisition of students who experienced two different pedagogical approaches to learning science, technology, engineering and mathematics through astronomy (STEM-A). The objective of this study was to explore the impact of a digital storytelling (DST) educational technology intervention…

To span the great distance from the solar system to the farthest clusters of galaxies in the universe, astronomers break down the distance indicators into steps. The nearest ones are measured geometrically, with what is known as parallax. Among the objects whose distances are thus directly measured are a rare type of star known as a Cepheid…

Participants' engagement in massive online open courses (MOOCs) is highly irregular and self-directed. It is well known in the field of television media that substantial parts of the audience tend to drop out at major episodic, or seasonal, closures, which makes creating cliff-hangers a crucial strategy to retain viewers (Bakker, 1993; Cazani,…

We live in a neurodiverse world, and therefore need to ensure that equally diverse educational opportunities are accessible to all learners. The term "neurodiversity," coined by Judith Singer (1999) describes the broad, and complex, spectrum of human brain functionality. Terms like "neurodivergent" or "neurodistinct"…

Throughout its history, Pluto has held interest for many as an underdog planet--as "the little guy" fighting for recognition. After years of debate, the International Astronomical Union (IAU) officially revised its definition of planethood in 2006, downgrading Pluto from full planetary status to "dwarf planet" (Retrieved August…

Formative assessments serve to engage students in active sense-making, making them critical tools for both teachers and students. Though formative assessments may be an informal mode of assessing, they are one of the most important, especially when teaching science. As a subject, teaching science does not have the same kind of beginning-middle-end…

We present results of a two-semester study to gauge the impact of collaborative two-stage exams on student learning and attitudes in university-level introductory astronomy classes for non-science majors. In the collaborative two-stage exam setting, students first completed an exam individually, and then they reconsidered a subset of exam…

Gravitational lensing is an interesting phenomenon in astronomy and is most typically given rise to by galaxies. The majority of the matter in a galaxy is thought to be dark matter, and the galactic gravitational lensing effect is mainly caused by dark matter halos. In gravitational lensing-related demonstrations in physics education, the feet of…

Research related to the teaching and learning of the lunar phases reveals a low level of understanding of this astronomical phenomenon by most students of all educational levels. Therefore, there is a need to develop didactic materials to promote adequate comprehension of this phenomenon and which have been tried out in the classroom. Presented…
