@suerobbins yes this is WordPress. Some of the interactive tasks are made with Storyline. Examples in this unit are the sample lessons on intros and conclusions, presentations, and preparing for a lecture. After your first reading task, there was a drag and drop summary and T/F question made in H5P.
I think a combination of H5P and Storyline works well, especially as some task types can lend themselves better to one or the other. We often start with Rise (which you see in week 4) and embed them into there.
