This study was a Design Based Research (DBR) project that aimed to examine the articulation of the theme of blood donation and Biology Teaching from the perspective of STS. The locus of the study was a federal school in Rio de Janeiro and involved teachers from the Biology department and 18 third year middle school students. The development DBR stages were: (1) analysis of the educational problem; (2) development of educational artifact; (3) assessment and intervention, and (4) reflection to produce design principles. Results indicated that teachers influenced the understanding of the educational problem and the research process. During the development phase, the teachers faced practical challenges related to the incorporation of technology in the pedagogical context. In the intervention phase, teacher and students evaluated positively the use of technology, especially when it referred to the articulation of the theme of blood donation to the teaching of Biology.
