GeCla, short for Generator and Classifier, allows the user to generate a pattern, a frieze or a rosette with a previously chosen kind of symmetry starting from an asymmetric motif. It also allows the classification (with or without help from the program) of the patterns, friezes, rosettes obtained in this manner. In the end, the program provides a report of the errors committed. GeCla already has versions in five (PT, EN, IT, GE, SP) languages. The generator writes encoded information about the existing symmetries in the jpg image file generated. Then the classifier reads and interprets this coded information, which allows it (according to the level of aid chosen) to give information about how the classification process is going, preventing wrong choices, or only indicating at the end whether the classification is correct and, if not, indicating the first mistake. GeCla also includes a competition option. In it, each player generates a pre-agreed number of images and then both exchange images and each classifies the other's images. All steps are managed by the program, which in the end provides a report on eventual mistakes.

Atenção! Esta aplicação é exclusiva para professores registados na Escola Virtual e funciona como apoio à funcionalidade QuizEV com cartões. Esta aplicação não pode ser usada separadamente. O QuizEV Scanner permite ao professor lançar quizzes na plataforma Escola Virtual e recolher as respostas dos alunos não sendo necessário mais nenhum dispositivo móvel para além do telemóvel ou tablet do professor. Basta o professor entregar a cada aluno um cartão de respostas, que pode descarregar e imprimir a partir da plataforma Escola Virtual e, depois, lançar um quiz na Escola Virtual, sincronizar o seu telemóvel ou tablet e através da câmara do seu dispositivo, capturar as respostas que os alunos apresentam, levantando o cartão. O feedback relativo a quem respondeu certo ou errado é imediato e fica registado na área Turmas da Escola Virtual.
