The university also offers an on-campus writing lab with plenty of writing assistance; however, today, we’ll focus on the Purdue OWL specifically.

The Purdue OLW educational platform can also be used by educators and teachers in their classes or as an additional source of all-writing-related materials. It’s not exactly a platform where a teacher can organize a fully equipped lesson, as it’s not really designed for interactive instruction. However, it’s an easily accessible free educational resource with plenty of materials about writing. Teachers can use it to print out some pages or create presentations and supplement their lessons. For instance, here is a ready handout with subject and verb agreement exercises with answers:

OWL Purdue Citation Machine

Purdue OWL doesn’t have their own citation generator. Instead, they collaborate with Chegg to help students create citations faster and in the correct format. The embedded Chegg citation form can be found on every style’s page, and depending on the style, it’ll send you to the Chegg page, where citations can be created. For instance, you need to cite History of the Modern Suspension Bridge: Solving the Dilemma between Economy and Stiffness and Santiago Calatrava: Drawing, Building, Reflecting

How Effective Is Purdue OWL?

The Purdue OWL website offers free instructional materials and writing resources to a very broad audience of students and educators. Taking into account its lack of interactivity (which can be found on other paid educational platforms), the website can be used to its best advantage by those who know what they are looking for, have a certain level of writing competence, and can handle a large scope of material independently without guidance. The platform is considered an exceptionally informative resource for all things writing—research, writing styles, grammar, formatting and citation styles, English as a second language, and professional writing—therefore, it’s highly recommended for everyone who wants to get into all aspects of the writing process.
