During a 9th-grade English class, the teacher designs a
lesson around the theme Local Heroes. The students begin
by watching a short subtitled documentary about Mestre
João, a capoeira master who offers free classes to children
in the school’s neighborhood. Working in groups, they then
create posters and voice recordings in English to present
other individuals they know who make a difference in their
community. Some students choose sports figures, others
highlight musicians or teachers. In order to support the lesson,
the teacher prepares a didactic sequence that incorporates
elements of digital literacy. Throughout the activities, she
encourages students to express themselves meaningfully
in English, prioritizing authentic communication and social
relevance over grammatical perfection and form-focused drills.
