In language teaching, the focus is on four basic skills: reading, listening, speaking, writing. It is possible to create content for the first three of these skills by using H5P. Writing exercises, however, are hard to implement despite the existence of such content types as Essay.
My aim was to use H5P so that language learners can write and submit essays online. The submission process should not include a "download and post" phase. To this end, I decided to make use of the Documentation Tool and now I see that this content type can actually be used for sentence or essay writing.
I created an H5P file on H5P.org and your can see how the Documentation Tool can be used to evaluate the writing skill (https://h5p.org/node/617624).
Note: On this forum, I have come across several messages where users ask how to make the "Submit" button on Documentation Tool visible (on WordPress). The relevant reply is also present in this forum (https://h5p.org/comment/26898#comment-26898(. I use Moodle.
