This task asks readers to figure out why when you stir a cup of hot liquid and tap on the side of the cup with a spoon, the pitch of sound starts low and ends up high. The solution to last month's tasks relating to the circumference of the Earth and how many stars are in the (visible) sky is also presented.

From star systems to social systems, CONASTA 64 connects teachers to researchers and scientists working on the cutting edge of modern science. We asked two CONASTA 64 Keynote speakers, Steven Tingay and Ian Walker to share their passion for their work and their dedication for giving back to the science community.

In this fourth and fifth grade activity, students become comfortable with the concept that light-years are a measure of distance, not time, and discover how we are looking back in time when we look at stars. Since the enormous distances in space can make astronomical studies even more confusing, students explore the meaning of a light-year by…

Context-based approaches can bridge the gap between abstract, difficult science concepts and the world students live in. However, the relevance of specific contexts to different groups of learners, and its stability over time, have not been extensively explored. This study used four datasets, collected in different formal and informal settings, to…

As is true of a far more famous story, it all began a long time ago, in a galaxy far, far away. It even involved a binary star system. A small star, called a white dwarf, had become a burned out husk of its former self and it turned to gorging on hydrogen and helium from its bloated red giant neighbor. The transferred gas reignited the fires of…

Engaging freshman and sophomore students in meaningful scientific research is challenging because of their developing skill set and their necessary time commitments to regular classwork. A project called the Chondrule Analysis Project was initiated to engage first- and second-year students in an initial research experience and also accomplish…

Turkish preservice science teachers have been taking a two-credit astronomy class during the last semester of their undergraduate program since 2010. The current study aims to investigate the relationship between preservice science teachers' astronomy misconceptions and their attitudes toward astronomy. Preservice science teachers were given an…

Non-formal education and the dissemination of science are increasingly gaining importance around the world. Whilst astronomy in Brazil is no exception, its growth has however been slow and dispersed, institutions and activities across the country are uncoordinated, and no source exists that integrates relevant information and knowledge. To address…

[This paper is part of the Focused Collection on Astronomy Education Research.] This study investigates students' perceived impacts regarding their participation in course-based undergraduate research experiences (CUREs) in astronomy. Each research experience adopted one or more projects from the Research Based Science Education for Undergraduates…

The aim of this study is to examine the impact of the Technological Pedagogical Content Knowledge (TPCK) based educational practices in astronomy lectures on prospective science teachers' success levels. The study was conducted on 4th-grade prospective science teachers of a public university and lasted for 14 weeks. In the study,…

The paper presents an interactive module created through the Wolfram Demonstrations Project that visualizes the Zeeman effect for the small magnetic field strengths present in the interstellar medium. The paper provides an overview of spectral lines and a few examples of strong and weak Zeeman splitting before discussing the module in depth.…

Test-potentiated learning occurs when testing renders a subsequent study period more effective than it would have been without an intervening test. We examined whether testing only a subset of material from a multimedia lesson would potentiate the restudy of both tested and untested material. In Experiments 1a and 1b, participants studied a…

Creative and Tactile Astronomy is an educational project developed by English and Portuguese teachers. Isabel Borges and Lina Canas from Portugal and Alison Alexander and Ruth Wiltsher from the United Kingdom met for the first time at the 2013 Science on Stage Festival in Slubice-Oder, on the border between Germany and Poland. As a consequence of…

Cultures need to accurately record dates and times for various societal purposes, ranging from knowing when to plant crops to planning travel. In ancient times, the sun and moon were used as measurement devices because of the scientific understanding of the physical world at that time. Ancient timekeepers monitored celestial events and either used…

How can physics teachers help students develop consistent problem solving techniques for both simple and complicated physics problems, such as those that encompass objects undergoing multiple forces (mechanical or electrical) as individually portrayed in free-body diagrams and/or phenomenon involving multiple objects, such as Doppler effect…
