In this paper, we discuss the role of dialogue in two layers; first, in relation to two self-organised communities of science teachers in which we participated and, second, our process of coming together during our PhDs to analyse these communities, a dialogue about the dialogue. Regarding the first layer, there is much to learn from science teachers and science teacher educators when they are organised in sites of learning that can be spaces of hope, beginnings, and becoming, as is illustrated in the case of these two self-organised communities. Regarding the second layer, we discuss the value of dialogue and the possibilities it offers to develop ideas for science education in a way that might be democratising, emancipatory, and offering counter-narratives in a neoliberal Chile. By engaging in this dialogue revisiting the practices of our communities, we gained a sense of agency within the field of science education. However, we realised that we need to move towards a critical view within our communities, and more contextual and transformative science education by translating these sites of hope to our educational praxis today. For us, this relates both to developing a collective view of how to make science education provide pedagogical conditions and experiences for critical and engaged citizenship and thinking how we can act and engage with different settings in solidarity. One way of moving towards this is by developing a political knowledge of our disciplines through a collective scientific conscientisation. Our communities are the departure points to achieve this.
