Augmented reality (AR) is an emergent technology that overlays virtual objects into the real environment. Lately, AR is gaining prominence in education because of its increasing affordability through computers or mobile technologies. In addition, research sustaining the benefits of AR to promote student’s engagement to learn is increasing every day. However, the literature identifies lack of studies about the use of AR in education, namely, studies focused on the development of AR games designed over specific learning objectives (game-based learning). This paper presents a mobile augmented reality platform with learning purposes. The platform includes a mobile application that consists of a location-based game targeted to promote learning about the universe. Furthermore, it includes a back-office that allows teachers to introduce information about celestial bodies and also develop a set of multiple-choice questions to assess student’s learning about the subject matters they teach. The mobile application provides the users with physical movement and social interaction in the real world, while playing the game and for this reason it is included in the pervasive games’ paradigm. Besides engaging the students to play the game, we argue that this platform may be used as a resource to be implemented in informal and formal learning environments.

The implementation of an integrated approach of STEM education with real-life scenarios is crucial to motivate students to learn and to better prepare them for real-world challenges, which is a big challenge for teachers. Therefore, there are implications for teaching practice and consequently the need for professional development. This paper presents an integrated approach of STEM education developed in the context of a collaborative professional development programme implemented in an exclusive online context, provoked by the COVID-19 pandemic. The programme aimed at providing teachers with knowledge and skills to develop STEM integrated tasks to be implemented in class. This study used a quantitative–qualitative approach to answer the research questions, using mixed methods to collect data. Participants are primary school teachers who participated in the programme during four months in the school year 2020/2021. Based on data collected from questionnaires, participant observation and teachers’ final reports, it was verified that teachers recognized the importance of obtaining training in STEM education and that this type of professional development was very relevant and improved their knowledge and skills to implement STEM hands-on practices in class. In addition, a case study of a science and mathematics 6th grade teacher is presented to illustrate how she implement integrated STEM tasks in class based on a real-world scenario such as the COVID-19 pandemic. Finally, teachers recognized the importance of this approach and that it increases students’ motivation to learn.

Mobile augmented reality applications are gaining prominence in education, but there is a need to design appropriate and enjoyable games to be used in educational contexts such as classrooms. This paper presents an interactive information system designed to support the implementation of an augmented reality application in the context of game-based learning. PlanetarySystemGO includes a location-based mobile augmented reality game designed to promote learning about the celestial bodies and planetary systems of the Universe, and a web application that interacts with the mobile device application. Besides face-to-face classes, this resource can also be used in online classes, which is very useful in social isolation situations as the ones caused by the COVID-19 pandemic. Furthermore, it is the inclusion of the web application, with a back-office, in the information system that makes it possible to include curricula contents according to the grade level of students. Moreover, it is intended that teachers use the information system to include the contents they find appropriate to the grade level they teach. Therefore, it is crucial to provide their professional development to be able to use this resource. In this regard, a pilot study was conducted with teachers who participated in a STEM professional development programme in order to assess if the system is appropriate to be used by them. It is concluded that teachers found this resource relevant to motivate students to learn, and also acknowledged that the web application facilitated the introduction of appropriate curricula contents and also was useful to assess student performance during the game. Teachers need support, however, to implement these types of technologies which are not familiar to them. The necessary support can be provided through collaboration among the researchers and teachers in their schools. Besides engaging students to learn about celestial bodies, it is concluded that the information system can be used by teachers to introduce appropriate curricula contents and to be implemented in class.

This paper aims to present an interdisciplinary approach intended to raise awareness for Sustainable Development Goals in the context of STEM (Science, Technology, Engineering, and Mathematics) hands-on activities targeted to elementary and secondary school. In particular, contents related to the physics of sound are used to warn about the dangers of noise pollution and its consequences for health, well-being, and productivity. Therefore, it is crucial to inform and raise community awareness on this issue, as well as on the measures needed to prevent its consequences. This research is inserted in a broader pedagogical project that includes primary school and secondary school teachers’ professional development and visits to schools to perform several hands-on activities in class aiming to provide students with 21st-century skills related to STEM education. Based on the literature, questionnaires, and participant observation, an empirical study was conducted with teachers who participated in a professional development programme. It is concluded that teachers and students understood the dangers of noise pollution and the measures to be taken to prevent them. Therefore, higher education institutions have a crucial role in the community, namely, through partnerships with schools and teachers’ training centres to raise awareness and disseminate and increase Sustainable Development practices in the community.

The international academic community recommends the integration of Science, Technology, Engineering and Mathematics (STEM) education in order to better prepare students to face the increasing challenges of our real world. However, literature diagnoses difficulties related to the implementation of STEM integrated tasks by the teachers in school, related to the need of having enough specialised knowledge to achieve this goal. Teachers are the key to any process of a pedagogical intervention. In this regard, there is the need to promote their professional development, which raises the following question: What strategies of a professional development programme (PDP) provide teachers with motivation and confidence to innovate their practices? This paper discusses the role of leadership as an important strategy to promote the efficacy of a STEM PDP. With a qualitative methodology and an interpretative approach, a primary school teacher case study is presented. The teacher was able to develop STEM integrated tasks in the context of a collaborative network involving the team´s project leader, the school leaders and the training centre leader.
