Background: Being able to think independently is a must for students to construct new knowledge in their minds. Self-explaining is a constructive learning strategy that encourages students to think for themselves and to make inferences that go beyond the given information. The Self-explain--Discuss--Re-explain (SDR) strategy adapted from…

Multidisciplinarity and the enrichment of science and mathematics education toward the so-called STEAM-approach where the A stands for art, has raised a lot of academic interest in the past decade. In this study, 5th and 6th graders from the greater Helsinki area (N = 390) participated in a several months long, Mars-colonization themed…

Teaching astronomy to young generations is of great importance because astronomy education helps us to better understand the world we are living in and to find answers to our questions. In this regard, the current study aimed to determine the secondary school 4th grade students' mental models of the astronomer. The current research is designed as…

Alternative conceptions in astronomy are a road block to new learning. Astronomy content is included in the Australian Curriculum (AC) from Year 3 and then intermittently in Year 5, Year 7 and Year 10. In accepting that science is socio-culturally constructed, it is important for teachers to have a clear understanding of the alternative…

The PhD Plus 10 Study was the first-ever follow-up of mid-career physics PhD recipients. In 2011 individuals who graduated with a physics PhD from the classes of 1996, 1997, 2000, and 2001 in the United States were contacted. Of those who responded to the survey, 597 were employed in academia, 464 academic employees worked in physics or astronomy…

A long time ago in a galaxy far, far away, two black holes, one of mass 36 solar masses and the other of mass 29 solar masses, were dancing their death waltz, leading to their coalescence and the emission of gravitational waves carrying away with them three solar masses of energy. More precisely, it happened 1.3 billion years ago at a distance of…

On August 21, 2017, sky gazers all across North America will experience a total solar eclipse, arguably the most breathtaking of all astronomical phenomena. The August eclipse is an ideal astronomical event to observe with young children because it allows them to observe a powerful and easily accessible astronomical phenomenon. Observing…

This column provides background science information for elementary teachers. This month's issue discusses the rotation of the moon. The author investigates what would happen if the moon did not rotate and addresses exactly why the Moon does what it does with respect to rotation.

The Great American Total Solar Eclipse (TSE2017) will occur on August 21 this year--the first total solar eclipse in the continental United States since 1979. For many reasons, this is a scientific and educational milestone event of the highest magnitude that should not be missed by any teacher and student whether or not their school is in session…

Science, technology, engineering, and mathematics domains draw heavily on spatial reasoning (NRC, 2006). One particular science thought to be especially spatially-complex is astronomy. Understanding astronomy requires using a "space-based perspective" to explain phenomena we see from an "Earth-based perspective." That is, it…

The purpose of this research was to examine the effect of the 5E teaching model on the primary school pre-service teachers' (PSPTs) learning some astronomy concepts. The sample of this research consisted of 90 PSPTs in the 2nd year at a state university. The research was carried out on the pre-experimental methodology with a single research group.…

As computer-based visualization techniques are becoming more important across the landscape of astronomy education, this pre-test/post-test study using the Size, Scale, and Structure Concept Inventory (S3CI) looked at the impact of using a hybrid combination of hands-on and computer-based activities on the learning of five semesters of non-science…

The discovery and characterisation of planets orbiting distant stars has shed light on the origin of our own Solar System. It is important that college-level introductory astronomy students have a general understanding of the planet formation process before they are able to draw parallels between extrasolar systems and our own Solar System. In…

The Academic WorkForce Survey has been conducted every two years since 1986. Between March and June 2018, researchers contacted 797 physics and astronomy departments (including 39 astronomy-only departments) that award a bachelor's degree or higher in physics or astronomy. Responses were received from 720 institutions, a 90% response rate. This…

It is a common practice to fix a vertical gnomon and study the moving shadow cast by it. This shows our local solar time and gives us a hint regarding the season in which we perform the observation. The moving shadow can also tell us our latitude with high precision. In this paper we propose to exchange the roles and while keeping the shadows…
