For this project, I decided to combine my love of drawing, baking, and nature in order to create a drawing representing my metaphorical journey. In this piece of artwork, The waterfall symbolizes my progress over the school year and how it has created multiple “rabbit holes” in which I have jumped in in order to get to where I am today. My journey, like when eating a cake, started out on the highest and smallest tier and ended at the largest tier on the bottom. Through this, you can see that as I went on my journey my horizons widen, there are more contributing factors to my life, and things get more complex, as well as a lot more interesting. Also, my development over the past school year is represented by the changing of the animal, as well as the habitat that is placed in on every tier as the journey progresses.

In the article "More Than Words: Comics as a Means of Teaching Multiple Literacies" by Dale Jacobs, the author uses the term "multimodal text" to refer to forms of communication that use multiple modes or channels to convey information and meaning. In the context of this article, Jacobs is specifically referring to comic books as a form of multimodal text. Jacobs argues that comic books are an example of multimodal text because they combine written text with visual elements such as images, symbols, and visual cues to create meaning. He believes that comic books offer more than just traditional written text and serve as a means of conveying complex ideas and emotions through a mixture of written and visual elements.

Van Deursen and van Dijk (2014) resume this perspective, but stating that the great diversity of definitions makes it difficult to have a clear characterization of digital skills. Therefore, they propose a definition of digital skills, both conceptual and operational, in four sequential domains: Operational, formal, information and strategic. The authors understand by operational skills the actions that allow a person to use digital media tools, such as navigation bars, buttons or links, different ways to input information in fields or pages, possibilities to download or save files and similar. As for the formal skills, they refer to navigation and orientation in structures specific to digital media (in essence, hypertextual), such as knowing which website one is in, identifying how to navigate each site, orienting oneself or getting lost while performing a task. The information skills are related to knowing how to search, select and assess the information from internet in its various forms (text, image, video).
