Flexge é uma metodologia de ensino de inglês totalmente interativa, construída exclusivamente para Centros de Idiomas e Instituições de Ensino Fundamental, Médio e Superior. Na Flexge o aluno trabalha as 4 habilidades linguísticas de modo empolgante e eficiente, priorizando fala e escuta em inglês. A fala do aluno é comparada com a pronúncia de mais de cem nativos através da nossa poderosa ferramenta de reconhecimento de fala. O aprendizado de qualquer idioma ocorre pelo desenvolvimento das 4 habilidades linguísticas, isto é, ouvir, falar, ler e escrever. Contudo, os métodos tradicionais de ensino de inglês trabalham com muito maior ênfase a leitura e a escrita do que a escuta e a fala. Tal situação decorre de o ensino ser focado na resolução de exercícios em livros didáticos, acarretando em maior insegurança do aluno para situações de conversação. Através da união entre a tecnologia e o coach em sala de aula, conseguimos que o aluno ganhe confiança para se expressar cada vez mais em inglês, tornando o aprendizado ativo e significativo. A Flexge promove a personalização do ensino através da aplicação de ensino híbrido (blended learning), combinando uso da plataforma online com as atividades regulares em sala de aula. Os desafios propostos pela Flexge fazem com que o aluno estude inglês continuamente fora do ambiente escolar, podendo utilizar o momento da sala de aula para dinâmicas de conversação e suporte pedagógico de seu coach. Na Flexge o aluno estuda inglês de maneira ativa. Através de um avançado sistema de reconhecimento de voz, o aluno fala inglês desde a primeira unidade e compara sua pronúncia com a fala de mais de 100 nativos de diferentes localidades. A metodologia Flexge estimula a fala em inglês fornecendo feedback objetivo ao aluno sobre seu desempenho nesta habilidade. O foco é na aprendizagem personalizada onde cada aluno faz exercícios de acordo com o seu nível de inglês, permitindo que, numa sala de aula com diferentes níveis de proficiência, os alunos possam receber o estímulo adequado para ganharem confiança com o idioma. Certificados de Inglês de Padrão Internacional A metodologia Flexge está alinhada com o sistema de proficiência de idiomas do Quadro Comum Europeu, compreendido pelos níveis A1, A2, B1, B2, C1 e C2. Os alunos podem cursar a disciplina de Inglês de maneira personalizada, de acordo com o nível pessoal de proficiência, e seguindo os parâmetros internacionais do idioma. Além disso, que recebam certificados a cada novo nível de inglês conquistado! É isso que a Todo conteúdo pedagógico da Flexge segue o Quadro Comum Europeu de Referência para Línguas, inclusive os testes de certificação. Assim, o estudo de inglês se torna algo vivencial e palpável onde o aluno sempre possui metas muito claras para alcançar novos níveis de proficiência.
