Mastering a language not only involves four language skills—listening, speaking, reading, and writing—but also mastering the grammar and vocabulary of the language. This research was intended to investigate the perceptions of Indonesian undergraduates and their lecturers at the Islamic University of Riau toward the use of Socrative in grammar class specifically tenses. This study employed a quantitative research design. The respondents were 34 sixth-semester undergraduates who were randomly chosen and two grammar lecturers at the English Department of Islamic University of Riau in the academic year 2016/2017. The questionnaire was adapted from the technology acceptance model (TAM) by Davis, which consists of two specific variables: Perceived usefulness and perceived ease of use. Before the questionnaire was employed in this study, a pilot study was carried out to ensure the validity and reliability of the instrument. The findings of the research show the majority of respondents have positive perceptions toward Socrative. The students and lecturers provide positive responses with regard to “perceived usefulness and ease of use” of Socrative in grammar class. It is hoped that this tool not only could be used in grammar class but also in all aspects of English language learning. It is also expected that this research could assist Indonesian educators to teach more creatively.
