Language learners often face communication problems when they need to express themselves and do not have the ability to do so. On the other hand, continuous advances in technology are creating new opportunities to improve second language (L2) acquisition through context-aware ubiquitous learning (CAUL) technology. Since vocabulary is the foundation of all language acquisition, this article presents ULearnEnglish, an open-source system to allow ubiquitous English learning focused on incidental vocabulary acquisition. To evaluate our proposal, 15 learners used the developed system, and 10 answered a survey based on the Technology Acceptance Model (TAM). Results indicate a favorable response to the application of incidental learning techniques in combination with the learner context. ULearnEnglish achieved an acceptance rate of 78.66% for the perception of utility, 96% for the perception of ease of use, 86.5% for user context assessment, and 88% for ubiquity. Among its main contributions, this study demonstrates a possible tool for ubiquitous use in the future in language learning; additionally, further studies can use the available resources to develop the system.
Aprendizes de idiomas geralmente enfrentam problemas de comunicação aodesejarem falar algo e não saberem a palavra ideal. Além disso, os contínuos avanços da tecnologia estão criando novas oportunidades para a aquisição de vocabulário de uma segunda língua por meio da tecnologia. Este artigo apresenta um modelo de aprendizado ubíquo para auxiliar os estudantes de inglês a aprender novos vocabulários. O estudo avaliou a viabilidade de apoiar o aprendizado de inglês no contexto do usuário. Os resultados indicam uma resposta favorável ao uso do contexto para auxiliar o usuário em sua aprendizagem. Foi alcançada uma aceitação de 78,66% para a percepção de utilidade e 96% para a percepção de facilidade de uso.
