I have tried picovico.com which is an online cloud based photo to video maker. They have list of themes that is suitable for making an education video or slideshow that are best for teachers and students who are struggling to make a good decent videos. All we need is photos of the topic, you can add text / captions, you can even choose audio for background music, you can directly share videos in social media or download the video. It is most convenient online software.
