Sheppard wants to open the eyes of instructors to the wide range of skills needed to teach well. She argues that, "Oftentimes, teaching production of digital texts is viewed by those outside of the computers and composition field as simply a matter of imparting technical skill rather than facilitating development of diverse and significant literacies" (Sheppard, 123). Sheppard continues to move her argument forward by urging instructors to see how much "time and intellectual effort" (Sheppard, 123) must be exuded to execute a "developed, informative, persuasive, and engaging" of digital texts (Sheppard, 123). She is advocating that instructors move from merely prescriptive "texts" to descriptive;, that is, pointing more to the nonrestrictive or focusing on the character of actual material rather than abstract rules. Basically, she wants tools not rules (I apologize for the rhyming).
Sheppard stakes her claim based on personal experience of the text she was to create for the U.S. Forest Service Research Lab. The root of her argument is that production of media is not merely rhetorical or intellectual, but that you need both. Instructors must assess the audience, purpose, and objectives. Her goal was, "To communicate locally related, ecologically, and scientifically based information in a way that is appealing and informative to the target audience" (Sheppard, 123-124). She unpacks the obstacles that she had to overcome in the process, such as, the restraints of certain mediums or even the disagreement of her colleagues of who is the audience. She argues that in order to create this web site or any type of multimodal text that there is much more than traditional writing involved. Just like Alice in Wonderland, Sheppard had no idea how deep the rabbit hole went until she started falling.

I find it ironic that Sheppard is driving home to the audience in this text how important and central multimodal text can be, yet, her argument in this text is very limited. She may have created a fabulous website, but this article is going against what she is saying. It feels like an oxymoron article. How can you convince the audience how essential and intellectually challenging multimodal text can be to both teaching and learning, yet you cannot even use other mediums or modes in this same argument to us as readers. I agree with what Sheppard was trying to do and unpack, but I feel the argument fell short in delivery and impact on her audience.
