Investigation of students' understanding of speech with smart mechanisms and scaffolding in flipped classrooms

This study tried to investigate how to facilitate students' understanding of speech with smart mechanisms and scaffolding in flipped classrooms. This is because students usually faced difficulty to understand spontaneous speech content without any support in flipped classrooms. In order to enhance their understanding of speech, some support like speech text recognition (STR) texts or annotation have potentials to consolidate and verify their understanding of speech content. Furthermore, after speech if students were asked to write the report with some scaffolding will help students to concentrate and understand speech content deeply. Therefore, in this study, we developed a smart learning environment (SLE) that students can learn presentation slides or articles with annotation feature before class, listen and learn presentations with STR texts feature during class, then writing reports with SQCP scaffolding using Google Docs feature after class in flipped classrooms. Participants in this study were 25 graduate students that took seminar course in one semester to learn the speech. The result revealed that transcription generated by STR texts helped students to understand the presenter's speech before writing SQCP reports. In addition, the annotation triggered students to ask questions during class in order to get a deep understanding. Google Docs was useful to help students writing reports because students usually already use it in daily academic life. Moreover, regarding students' perceptions toward SLE it was found STR texts really help their speech understanding and report writing. Therefore, our proposed SLE was effective to facilitate students to writing reports in flipped classrooms.
