Is it sufficient to keep only audio recordings of student performance?
It depends on the mode of assessment. For group discussions, video recordings are better because you can see who is talking. For individual presentations, audio recordings would be sufficient. It also depends on the resources of the school. If it is not possible to make video recordings, audio recording would be better than no recordings at all. However, if only audio recordings of students’ oral language use are kept, teachers/students cannot later review the body language, eye contact, physical movement, smiles, flaws, and actual listening while other people are speaking, etc. There might also be greater problems with standardization if only audio recordings are used at the internal meeting at the end of the year.
