Holography can be a useful strategy for fostering public engagement in science and technology. Thus, an important application of holography is in education and science communication. The Holography4All program was developed and implemented to involve different types of audiences in holography and to study the applications of holography in science communication. This program involves holography labs, portable holographic darkroom, holograms exhibitions and interactive exhibits and it took place in museums, schools, science centers, libraries, maker spaces and outdoor places. This paper will present types of holograms and all holographic systems used and it will explore all holograms and results obtained.
During 2015, the International Year of Light, a traveling exhibition was developed and dedicated to holography. Despite the holograms are present in our day life, through several formats and different applications, for general public these 3D images are strange elements from complex technology. This exhibition explores several contents related with holograms, such as history, techniques, equipments, setups and applications and it involves a main structure with six interactive exhibits and a lab for hologram recording. The exhibition includes a group of nine art holograms, a workshop table dedicated to scratch holograms and a touch screen with information about holography, which can be download on-site or at home. All these contents, based on hands-on activities, are organized into five areas: "see", "do", "explore", "holo kids" and "to know more". The holography lab is based on a portable Denisyuk system and it allows the public to notice the typical darkroom environment needed to work on holography and also it allows visitors to make holograms as a souvenir of the exhibition. There are two types of visits: "Exploring the world of holograms" focus on visiting all contents and "Let's make an hologram" that, besides visiting, allows also to make holograms. Light Windows is an exhibition dedicated to the general public that during the last year has been traveling around six Portuguese cities. This paper will present and analyze all results obtained and it will discuss exhibitions impact on visitors.
Since 1997 a program dedicated to holography has been developed and implemented in Portugal. This program started with focus on schools and science education. The HoloNetwork was created and it has been spread at a National level, involving a group of thirty schools and hundreds of students and teachers. In 2009 this network started to work to achieve a new target, the general public. With this goal, a larger program was developed with focus on science and society and on science communication through holography. For the implementation of this new program, special holography outreach activities were built, dedicated to informal learning and seven Science Centers around Portugal were add into the HoloNetwork. During last years, we have been working on holography, based on two main branches, one dedicated to schools and with the aimed to promote physics teaching and to teach how to make holograms, and another dedicated to society and with the aimed to promote holography and to increase scientific literacy. This paper would analyze the educational program, all holography outreach activities, exhibitions or events, all equipments, materials and setups used and it would present the holographic techniques explored with students or with the public. Finally, the results obtained in this work would be present and explored, with focus on students impact and outcomes, taking into account the public engagement on holography and its effect into scientific culture and analyzing the quality of holograms made by students and by the general public. subject.
Holography is an optics technique based on wave physics and lasers with several applications at our day life. The production of holograms involves experimental work based on hands-on activities and creativity. All these elements can contribute to the promotion of experimental teaching of optics and training on holography. The hologram itself acting as a final result from a long process of research and study can enable the engagement of high school students on physics and promote the stimulus on optics learning. Taking these assumptions into account a network of schools working on holography was built involving thirty schools from all country. Holography systems were developed and several hands-on activities were constructed. During last sixteen years students are working on laser optics and holography producing different kinds of holograms. This study presents all holography labs implemented at schools and it will analyzed the holography systems and materials developed for students. Training strategy will be discussed and holograms obtained by students will be presented. Results obtained show us that holography can be implemented as a strategy for promoting the learning of optics and it is a particular way to involve students on experimental work and lab research. Results obtained during this study will be presented in detail and analyzed with focus on students performance. Educational results, teachers training, prizes and other positive outcomes will be discussed and compared.
