Chile is home to most of the world's largest telescopes, and astronomy research is robust in the country. However, astronomy education in Chile is much less mature. As an effort to increase its quality and coverage, more astronomy K-12 teacher professional development (PD) has been offered in Chile in the last decade, but the results of these…

We present two studies to investigate the extent to which attending a planetarium presentation increases secondary school students' understanding of the apparent motion of the Sun and stars. In the first study, we used the Apparent Motion of Sun and Stars (AMoSS) test in a pretest/post-test/retention test setting to measure learning gains and…

Course-Based Undergraduate Research Experiences (CUREs) have been shown to provide students with a variety of learning benefits including better conceptual understanding, improved critical thinking and data literacy skills, and increased interest in pursuing scientific careers. Additionally, CUREs provide students with opportunities to participate…

The study investigates students' ability to analyze visual literacy and digital literacy through open-ended inquiry activities with astronomical observations and Heaven View application. The investigation consists of assignments for students to carry out six different variations of observational activities. Supervision is given in introductory…

Concept maps are the tools used to facilitate meaningful conceptual learning. In this study, an augmented reality (AR)-based concept map (AR-ConMAP) application was developed to facilitate the concept map creation process to overcome the challenges that students face when creating concept maps. The study was carried out as a case study.…

Advancements in mobile technologies have accelerated mobile Augmented Reality (AR), and many applications have been developed and presented in online stores. This study aims to evaluate the accuracy of the AR model of the Solar System simulated in mobile AR applications located in the Google Play Store. The applications were examined in the store…

This study aims to describe the 3D model's online modules effectiveness in the practicing mastery of conceptual knowledge in solar system learning using an instrument which tested 58 7th-grade respondents from one of the junior high schools in Jombang, East Java, Indonesia. The respondents were then divided without randomization into 29…

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…

In this work, an adaptation is developed of the first observation attempted by Galileo to demonstrate the heliocentric hypothesis to be correct. The objective is to enable students in their final year of elementary school to confront by themselves the same contradictory evidence that Galileo confronted during the second decade of the 17th century.…

Solar eclipses are a rare phenomenon that everyone should have the opportunity to explore in depth. This article describes two programs developed by a science, technology, engineering, and mathematics (STEM) outreach center with the goal of bringing the excitement of eclipses to all learners. The STEM outreach center collaborated with local…

The present study focuses on the assessment of summer robotics camp designed for 7th grade students who were supposed to work on a STEM-related problem through modeling and design activities. It was exclusively investigated the effects of these activities on the STEM-related career interests and knowledge structures of students. The students were…

The purpose of this study was to provide an online astronomy activity using the Stellarium program as a virtual planetarium. The implementation was conducted with 30 preservice primary school teachers (PPTs) who participated in a non-formal workshop that included interactive, technology-based astronomy practices embedded with the…

Planetary motion in physics learning is an abstract concept and requires high reasoning. This article is one of the augmented realities (AR)-based pocketbook development on the planetary motion, focusing on student learning achievement. The study used the ADDIE model : "Analysis-Design-Development-Implementation-Evaluation". In the…

Planetariums have been used for a long time in astronomy education. Due to some disadvantages of permanent planetariums, it is seen that portable planetariums have become popular in recent years. Portable planetariums, due to their easy set up in anywhere, offer opportunities for those students studying in the regions where there are not…

The purpose of this open letter is to report on an innovative cross-cultural science education program that was introduced to upper primary and lower high schools across New South Wales over a four-year period. Titled 'Sky Stories', the program blends current Western science understandings with Indigenous Australian knowledge of astronomy in order…
