An art teacher wants to create an interactive gallery (wall) of famous artists for her students. Which of the following tools would be most suitable?

Padlet is a virtual pinboard tool ideal for building an interactive wall where students post and arrange content like an artists' gallery.

Screencast-O-Matic is a screen-recording tool for making video tutorials, not a collaborative wall.

Edpuzzle turns videos into interactive lessons with embedded questions, unsuited to a gallery wall.

Mentimeter is a live audience-polling and quiz tool for real-time responses, not a display board.

Padlet supports images, links and comments arranged as columns, walls or timelines.

Such collaborative pinboards support constructivist, learner-generated content.
