I agree with @jameshanlon and @bashar, in that these tools are student-led and student-paced, which allows for more student autonomy and self-direction towards their learning. It also breaks away from the traditional listening lesson or lecture, as they allow for reflection and discussion, which can lead to better comprehension. Time-wise, it helps the teachers enormously, as they can be set to be done asynchronously and then perhaps focus on the discussion in class.
One disadvantage could be the fact that students asynchronously get the chance to play the video as many times as they want, whereas listening done in class or perhaps in exams might be more controlled. Additionally, teachers need to dedicate much time in preparing the videos on these platforms. What is more, as in the example with Edpuzzle, the teacher might need to grade some of the responses, or in the instance of VideoAnt and TedEd, is not clear whether the teacher is required to engage in the discussion forums or assess performance, but also whether student participation in the discussions is mandatory and monitored. Hence, the impact on the learner might not be that clear, apart from informative and reflective.
At the end of the day, I believe students will find the experience using these tools useful, reflective and they will feel relieved of any pressure because it is self-paced.
