The Netherlands Research School for Astronomy (NOVA) has operated a Mobile Planetarium for over 14 years. Between 2009-2023, the project reached more than 400,000 learners and their teachers across the Netherlands. The project has been popular with schools since the beginning but continues to grow and reach increasing numbers of learners and schools each year. A project like the Mobile Planetarium does not continue growing this way without developing key ingredients or best practices. In this article, we describe the NOVA Mobile Planetarium project in detail and the challenges faced over the last 14 years. Reflection on the different aspects of the project has led to 10 best practices which have been critical to the continued success of this project. In this article, we aim to share our experiences to help other mobile planetarium projects around the world.

We present the Stargazing Live! program comprising a planetarium experience and supporting lesson activities for pre-university physics education. The mobile planetarium aims to inspire and motivate learners using real telescope data during the experience. Learners then consolidate their learning by creating conceptual models in the DynaLearn software. During development of the program, content experts and stakeholders were consulted. Three conceptual model lesson activities have been created: star properties, star states and the fusion-gravity balance. The present paper evaluates the planetarium experience plus the star properties lesson activity in nine grade 11 and 12 classes across three secondary schools in the Netherlands. Learners are very positive about the planetarium experience, but they are less able to link the topics in the planetarium to the curriculum. The conceptual modelling activity improves the learners understanding of the causal relationship between the various stellar properties. Future work includes classroom testing of the star states and fusion-gravity balance lessons.

Stargazing Live! aims to capture the imagination of students with a combination of live and interactive planetarium lessons, real astronomical data, and lessons built around interactive knowledge representations . The lessons were created using a co-creation model and tackle concepts in the pre-university (astro)physics curriculum which students find difficult to grasp with traditional interventions. An evaluation study in nine Dutch classrooms showed that learners are inspired and engaged by the planetarium but are not always able to link the content to the classroom.

Stargazing Live! aims to capture the imagination of students of all ages with live and interactive (mobile) planetarium lessons about the transient universe incorporating semi-live data from the Dutch MeerLICHT and BlackGEM telescopes. The most advanced lesson, at pre-university physics level, also aims to support the teaching and learning of key curriculum concepts. Results from the evaluation study show that pre-university physics students are engaged and inspired by the planetarium lesson but find it difficult to link the topics to what they learn in their physics lessons, supporting the need for follow-up classroom-based activities. To address this omission, lesson activities have been created for this age group to accompany the planetarium shows using the interactive tool DynaLearn (https://dynalearn.nl/). The lessons challenge students to model key curriculum concepts linked to the telescopes and their science such as stellar properties and the balance within a main-sequence star. The lessons were created using a co-creation model – led by science education experts with significant input from astronomers, astronomy outreach/education professionals and physics teachers. Knowledge questionnaires, completed immediately prior to and after the ‘stellar properties’ activity showed a significant increase in the number of students able to correctly describe the causal relationships between mass and other properties in a main sequence star such as luminosity, gravity, and temperature.

NOVA coordinates a group of three inflatable mobile planetariums which visit around 200 primary and secondary schools per year (~30,000 students/year). After an initial stop in activities (March-June 2020) due to the COVID-19 crisis, NOVA restarted school visits in July 2020 using a high quality flat-screen. Since the start of the second peak of the COVID-19 pandemic in October 2020, the decision was made to suspend visits to secondary schools until at least the end of 2020. In late October and early November NOVA has performed extensive testing with a variety of online tools to continue to reach out to schools during the second wave of the pandemic in the Netherlands. In this article we describe the different platforms, discuss the technical considerations and report on the experiences with the first schools.

This paper presents three qualitative models that were developed for the Stargazing Live! program. This program consists of a mobile planetarium that aims to inspire and motivate learners using real telescope data during the experience. To further consolidate the learning experience three lessons are available that teachers can use as follow up activities with their learners. The lessons implement a pedagogical approach that focuses on learning by creating qualitative models with the aim to have learners learn subject specific concepts as well as generic systems thinking skills. The three lessons form an ordered set with increasing complexity and were developed in close collaboration with domain experts.

NOVA—The Netherlands Research School for Astronomy—coordinates a group of three inflatable mobile planetariums that visit around 200 primary and secondary schools per year (approximately 30,000 students/year). After an initial stop in activities (March-June 2020) due to the COVID-19 crisis, NOVA has invested in a high quality screen in order to resume planetarium operations safely during the pandemic. The same interactive shows as present-ed in the dome are now given in a large, darkened room projected onto a flat screen with students sitting on cushions in a close group (current Dutch regulations allow close contact between children under the age of 18). A test of this COVID-19-safe “mobile planetar-ium” at a summer school for primary school children (ages 7-11; 180 students; 20 teachers) was highly successful. The evaluation showed that all participants found the experience to be highly inspi-rational. The expert presenters felt that the setup with the screen enhanced the interaction between the presenter and the students.

Although Pedagogical Content Knowledge (PCK) is traditionally defined as a static quality that teachers possess and apply in practice, we conceive of PCK as constituted by a dynamic, mutually influencing process between teacher and students. This co-constructing process is expressed in real-time interaction and defined by us as Expressed Pedagogical Content Knowledge (EPCK). The aim of this study is to develop a practically usable instrument that can track the microgenetic moment-to-moment interaction that embodies EPCK, and that enables us to observe different features and levels of EPCK in the form of changes in this interaction dynamics. We were interested to know how EPCK emerges and develops on the short-term time scale of classroom interaction. After presenting a general account of complex dynamic systems based measurement of psychological constructs (e.g., PCK), we describe a coding scheme for teacher-student interactions, based on theoretical EPCK components. The instrument was applied in an empirical observation study of a visit to a mobile planetarium by a grade 3 primary school class. A principal factor analysis was used to find latent EPCK components. Results show, firstly, that the instrument was reliable. Secondly, the variables in the coding scheme were relevant in view of the underlying theory. Thirdly, over the time course of the teaching session, latent components displayed various levels of EPCK – high, low or no ECPK. Instead of being an enduring or stable property of teaching-learning interactions, EPCK is a dynamic property occurring in the form of sequences of high and low levels, and corresponding peaks in the latent factors. Notably, EPCK did not appear in the form of a continuous steady state level but occurred in the form of bursts of high-level EPCK. We conclude that our coding scheme provides an adequate method for studying pedagogical content knowledge as it self-organizes in the form of real-time activity in the classroom.

We need mental and physical reference points. We need physical reference points such as signposts to show us which way to go, for example to the airport or the hospital, and we need reference points to show us where we are. Why? If you don’t know where you are, it’s quite a difficult job to find your way, thus landmarks and “lieux de memoire” play an important role in our lives.
