Research has shown that hands-on projects promote stem education, namely via problem-solving. CanSat, literally 'satellite in a can', is a stem educational project promoted by the European Space Agency. This paper addresses this issue by researching this STEM project and trying to understand how secondary students solve problems in the STEM CanSat project. We use qualitative techniques of data collection and analysis. The results showed that students used sophisticated thinking strategies to process information within this interdisciplinary project: (a) cognitive testing, cognitive organization, cognitive regulation, and monitoring, in addition to computer language and physical-mathematical calculations, are cognitive and metacognitive behavior strategies revealed in the CanSat; (b) problem-solving was suggested as a specific model, where students' higher cognitive and metacognitive ordering processes deepen in project development; (c) computational, lateral, or divergent and convergent thinking were detected as thinking types of students associated with and mobilized in the course of problem-solving. The findings of this research have practical implications for STEM education in space science. Hands-on projects using problem-solving are an essential strategy to promote STEM. This project reinforces this. Additionally, they are a starting point to promote meaningful learning and new thinking types.

Science communication training plays a crucial role in enabling scientists to effectively connect with the public, emphasizing essential skills such as building trust in scientific and technological advancements. Despite significant progress, some studies show a notable deficiency in higher education (HE) institutional structures and mechanisms dedicated to science communication training, addressing a diverse audience including researchers, teachers, and science monitors. This study delves into the key characteristics of current science communication postgraduate training programs within the HE landscape of Portugal. Our analysis is based on a comprehensive examination of the curricula of five science communication doctoral programs offered by four public universities in Portugal. The research involves a meticulous review of course documents and insights gathered from five directors through a detailed questionnaire. The primary objectives of this research are to discern the specific goals pursued by each course, uncover the content and development of competencies within their curricula, and explore the market opportunities envisioned by each offering. The results underscore that these programs equip students with the necessary competencies to effectively address challenges in science communication, notably enhancing public understanding of science. Significant findings suggest that Portugal's current higher education scenario predominantly emphasizes cultivating postgraduate training activities in authentic settings, fostering collaborative partnerships with society. This article is a foundational resource for further exploration into the discipline-specific applications of science communication, aiming to elevate academic engagement with society.
