Esperançar in uncertain times: the role of science and technology education in a changing world

Exactly 20 years ago, in 2002, the IOSTE International Symposium was held for the first time in Latin America, and also for the first time in Brazil, themed “Rethinking Science and Technology Education To Meet the Demands of Future Generations in a Changing World”. More than 500 educators from all over the world gathered in the city of Foz do Iguaçu to discuss the event's theme and various aspects of Science Education. The world imagined in 2002 as that one of future generations has become the world we are living in today. Twenty years after that imagined world in 2002, the 2022 event's theme mentions, once again, a changing world. Were the changes the IOSTE community faced twenty years ago still the changes we are dealing to today?

The year of 2020 brought a disruption that drastically altered the routine of billions of people around the world. The COVID-19 pandemic has exposed problems that existed before and that have been aggravated in the current circumstances. It has become paramount to talk about contemporaneity and consider the decisive role of the pandemic in recent years in themes such as the profound inequalities (economic, social, gender and race) that plague the world. Adding to it , there are previous and no less urgent discussions about the contradictions of the so-called Anthropocene, and the epistemological and ontological challenges associated with a system in deep crisis. This crisis seems to point to the scenario of changes and urgency in which we live, with the feeling that we are running out of time in relation to climate and social emergencies on the planet. It suggests that the changes and uncertainties that the theme of IOSTE 2022 refers to are of a very different nature from the world’s 20 years ago.

As it is a time of emergencies and crises, it also presents itself as a time of struggle. In such a context, we witness the emergence of social movements, an intensification of political and environmental activism, and agendas aimed at equity gained strength in discussions held around the world. In the Andean countries, the Mapuche (Wenufoye) and Whippala flags have brought, along with their struggles, a time of hope and resistance to other peoples around the world and peoples who join their struggles in their territory.

Against this backdrop, we present the theme of the XX IOSTE International Symposium: "Esperançar in uncertain times: the role of science and technology education in a changing world." The term esperançar is a neologism in Portuguese, created based on Freire's thought, derived from “esperança” (hope) and “esperar” (wait). According to Freire, “Hope (esperança) [...] does not consist in crossing one's arms and waiting. As long as I fight, I am moved by hope; and if I fight with hope, then I can wait” (Freire, 2005, p. 92)

It is therefore a verb that translates hope into action - esperançar. By proposing this theme, we intend to encourage the IOSTE community to think about possible collective futures, considering that education never occurs in a political vacuum, as Freire teaches us. We want to involve teachers of basic and higher education and the entire community of researchers in science and technology education in debates involving critical and post-critical pedagogies, social movements, decolonial perspectives, as a source of hope and resistance in science education. May this act of esperançar for reality through knowledge in science and technology and the ancestral knowledge of all peoples on Earth, serve as a support for us to think and act on the problems that affect the world.

IOSTE Organizing Committee

IOSTE Organization

The International Organization for Science and Technology Education (IOSTE) is an international organization which aims to encourage informed debate, reflection on and research into science and technology (S & T) education. IOSTE was established in 1979 to promote contact and dialogue across political and ideological borders. A key concern is that education in S & T should be a vital part of the general education of the peoples of all countries.

IOSTE has a board (committee) with representation from all regions of the world, and convenes international as well as regional symposia. These symposia provide for scholarly exchange and collaboration.

The symposia gather researchers, policy makers, teachers and others who are concerned about how science and technology can contribute to the outlined in our mission statement.

Conference format

The IOSTE International Symposium 2022 will be held in a hybrid format, allowing participants in two modalities: in person and virtual.

In the in person modality participants will be able to participate in all activities offered by the Symposium: pre-conference, cultural activities, overture, keynotes conference, symposiums, PhD & Early Career Meeting, Regional Meetings, final assembly/closure and oral and poster in-person sessions.

In the virtual modality, participants will be able to participate in: overture, final assembly/closure and keynotes conference by live streaming on Internet. Moreover, it will be possible to participate in the PhD & Early Career Meeting, Regional Meetings, symposiums and oral online sessions through the ZOOM Meeting platform.

The hybrid format of the event was proposed in order to congregate the maximum of participants around the World, considering the financial and sanitary issues that assolate different countries.

IOSTE Xilogravura

The visual identity of the IOSTE Syposium 2022 is based on xilogravura art. Xilogravura is an engraving technique in which wood is used as a matrix and enables the reproduction of the image engraved on paper or other suitable support. It's a process much like a stamp.

Even being a technique developed since century VI in Chinese culture and used in European middle Ages, in Northeast of Brazil it was incorporate as a cultural manifestation to represents popular stories of the quotidian and folk myths from northeastern people. This manifestation was through the called cordel literature, combining the xilogravura art with poetry to tell about cultural elements from Northeast region.

The main brazilian artist from xilogravura and cordel literature are Gilvan Samico, José Costa Leite, J. Borges, Amaro Francisco e José Lourenço. You can learn more about them and other representative cultural manifestation from Brazil at

Call for Proposals and strands

The theme of the IOSTE 2022 Symposium is Esperançar in uncertain times: the role of science and technology education in a changing world. This theme stresses the necessity to think about the relation between science and technology in a broad way, focusing on how this knowledge can help us in dealing with a world in constant change. Then, it is important to emphasize the nature of this knowledge, with cultural and human values, highlighting the promotion of dialogue across political and ideological borders to recognize sustainability, cultural diversity and international understanding.

In this sense, we invite all the community to submit your paper or symposia according to the following strands:


Strand 1: Student understanding and learning in STE (Student motivation and interest in STE)
Strand 2: Teaching science and technology in diverse contexts (Informal education of science and technology)
Strand 3: Use of educational technology in STE
Strand 4: Teacher education and professional development in STE
Strand 5: Higher Education in STE
Strand 6: Cultural, Social and Gender Issues in STE
Strand 7: Special and inclusive education in STE
Strand 8: Environmental and Health perspectives in STE
Strand 9: History, sociology and philosophy in STE
Strand 10: Decolonial, Social Justice, Critical and Transformative perspectives in STE


The XX IOSTE International Symposium will admit three types of paper presentations, for both in-person and virtual modality: Symposium; Poster session and Single oral presentation. For each of them, contributions can be empirical studies or theoretical/ Non-empirical studies. All proposals must be original that have not been published or presented at any other conference.

Symposium: This presentation format enables to jointly illuminate a topic from multiple perspectives, providing a coherent set of projects for discussion. Each symposium will be organized by a chairperson and will contain 3 - 5 presentations concerning a common topic of interest as well as one symposium discussant. The symposium is scheduled for 90-minute sessions, of which the final 30 minutes are to be moderated by the discussant to open up for an in-depth discussion of the projects presented.

The symposium chairperson is in charge of submitting:

a) presentation of the whole symposium: title, short abstract (150 words at maximum) and a synopsis for the whole symposium (500 words at maximum, excluding references)
