The document presents a case study of Nettilukio, an online Finnish upper secondary school program that caters to adults aged 17-75, including those living abroad and with special needs. Funded by the European Commission and integrated into the national school system, it emphasizes personalized learning, flexibility, and the use of Web 2.0 technologies, such as virtual classrooms, blogs, and wikis. Students can tailor their studies with no formal tests, focusing instead on portfolio building, with support from mentors and teachers to enhance communication and motivation.
