RESUMEN
In the pandemic era, we have started use the vaccination to prevent COVID-19 infection 3-4 months ago. COVID-19 vaccinations may have some unexpected adverse effects in the same as other all medications. In Europe, unusual blood clot after Astrazeneca COVID-19 vaccination (AZ vaccine) were reported to European Medical Agency (EMA) on early March. On 7th April 2021, EMA has declared this event 'possible side effect of AZ vaccine'. The name of this very rare side effect is known as blood clots with low platelet count in common term, and "Thrombosis with Thrombocytopenia Syndrome (TTS)" in scientific term. Unreasonable fears and myths is widely reported in Korean journals about this very rare side effect. The most important issue about this unreasonable fear is improper use of terminology for blood clots or thrombosis. In this presentation, I will explain the exact meaning of this TTS in Korea.
RESUMEN
Citizen science education is a new approach in science education for promoting scientific inquiry related to localized problems and for engaging in social action based on inquiry results. Using agency as a lens for understanding teachers' practices when using this approach is important. In this ethnographic case study, a teacher implementing a citizen science education program using Arduino was investigated from an ecological approach using temporal and relational dimensions of agency. In the iterational dimension, the teacher's own experiences and traits from life and professional histories were identified. His identity as a teacher and his religious values formed the projective dimension. Encouraging administrators, the financial difficulties of the school, and the COVID-19 pandemic were major elements of the practical-evaluative dimension. Findings reveal the complex array of the teacher's agency in the context of implementing citizen science education with Arduino with students, which contributes new understandings about science teacher agency. © 2022 by Na et al.
