This article uses the concept of "boundary object", first developed within science studies by Star and Griesemer, to analyse curriculum policy implementation. It employs as a vehicle a significant but contested reform of the science curriculum in schools in England from 2006 onwards, drawing empirically on an extended study of the…

Investigating stars can be difficult. The five-day unit presented in this article is designed for fifth graders to work toward Next Generation Science Standard (NGSS) performance expectation 5-ESS1-1, with each lesson lasting about 30 minutes. Students investigate the relationship between the brightness of light and distance, apply their…

In this study, it is aimed to reveal the models related to star subject as one of the concepts of astronomy of prospective science teachers before and after the current instruction through model analysis. This modeling situation is expressed as a Grounded Mental Model (GMM), since there will be a mental modeling that is revealed according to what…

In this study, high school and first-year undergraduate students were asked about their understanding of stars. The hypothesis guiding this research posits that high school students who have taken a semester-long astronomy course will have an understanding of stars most related to scientific knowledge, compared with high school students enrolled…

The purpose of this case study was to determine if there is an increase in third through eighth grade teacher job satisfaction and self-efficacy following participation in the informal science education STEM Science Teacher Residency (STaR) program held at a science center. Through this study, cohorts of third-eighth grade educators in Arizona's…

Discusses inquiry-oriented science instruction and experientially based programs that support newer instructional strategies. Also provides examples of six process-oriented programs (Cat Lab, Geology Search, Rocky's Boots, Tell Star, Volcanoes, What's in Your Lunch?). Level, hardware needed, publisher, and description are provided for each…

Background: In science education asynchronous online interactions have increased dramatically during the recent pandemic and some of these practices will stay. One of the characteristics in asynchronous exchanges is the spacing and sequencing of online interaction. It means that dialogue partners do not necessarily receive immediate feedback as is…

The purpose of this qualitative grounded theory study was to describe and explain children's thinking present in multiple related contexts surrounding a single Earth Space disciplinary core idea in order to provide insight on whether and how children's everyday thinking forms the basis for learning in science classrooms. As most previous work on…

Scientific research is undergoing a "big data" revolution, as probes deployed in oceans, the atmosphere, and outer space provide near real-time data streams. As more and more data sets such as Ocean Tracks become available online, opportunities to engage students in the "Next Generation Science Standards" (NGSS Lead States…

This dissertation looks at the effects of an educator-scientist partnership on the creation of an inquiry based science lesson for the middle school classroom. The lesson was initially created by a scientist following their science research, but changed as the scientist began working with teachers. The changes in the lesson show that scientists…

Purpose: The purpose of this paper is to evaluate how institutions of higher education (IHEs) in the USA communicate sustainability through their websites. Specifically, the authors compare how and to what extent sustainability is communicated through an institution-wide sustainability website versus operational and academic department websites.…

Although concept inventories are among the most frequently used tools in the physics and astronomy education communities, they are rarely evaluated using item response theory (IRT). When IRT models fit the data, they offer sample-independent estimates of item and person parameters. IRT may also provide a way to measure students' learning gains…

Science is frequently a visual endeavor, dependent on direct or indirect observations. Teachers have long employed motion pictures in the science classroom to allow students to make indirect observations, but the capabilities of digital video offer opportunities to engage students in active science learning. Not only can watching a digital video…

What kinds of astronomical lab activities can high school and college astronomy students carry out easily in daytime? The most impressive is the determination of latitude and longitude from observations of the Sun. The "shooting of a noon sight" and its "reduction to a position" grew to become a daily practice at the start of the 19th century…

The authors teach an astronomy unit in their seventh-grade course that they find never fails to motivate and stretch the imagination. The questions students ask are wonder-full: "What was here before the universe?" "If there was nothing before the Big Bang, where did energy and matter come from?" "Does the universe have a boundary, and if it does,…
