Although the features of the technology thus far described have long been a part of the classroom, recent advances can help the ease with which they can be used. Audio recordings may now be more easily made by the student using an ordinary laptop computer, whereas until relatively recently such technology was not as easily accessible . The potential for setting tasks for students at home may be allowed by asking them to watch a video on a video hosting site, which was previously a more difficult task to complete where only videotape was used. However, there are also some challenges that are brought to the unsupervised use of such technology as audio technology may be used to slow down or to stop and start a section repeatedly . On one hand, there is no harm in this being done to practice, and may in fact represent a useful tool for the student to work at their own pace without feeling penalised by the classroom experience . This can allow a more student-centred approach to language learning, allowing the students to complete some tasks at their own pace, freeing up space in the classroom for class-based activities.
