Thought I would share some bits of my thesis on Twitter, PLN’s and PLE’s  as others might find it useful.

What is a PLN?

For all of the conversation occurring among educators about PLNs, there has been surprisingly little academic research on PLNs (Couros, 2010, p. 123). With many educators using this term to describe their own informal learning habits, it is important for educational researchers to investigate exactly what this concept means to those who are using it as a term to describe a learning activity

A Personal Learning Network (PLN) is a network of people you connect with for the specific purpose of learning (Tobin, 1998). These people may assist you in your learning by acting as a guide, direct you to learning opportunities, and assist you with finding answers to questions (Tobin, 1998).

Digenti (1999) defines a PLN as:

relationships between individuals where the goal is enhancement of mutual learning which is based on reciprocity and a level of trust that each party is actively seeking value-added information for the other (1999, p. 53).

Couros (2010) echoes Digentis notion that a PLN is defined by the relationships among the individuals when he states that:

“a PLN is the sum of all social capital and connections that result in the development and facilitation of a personal learning environment” (2010, p. 125).

In order to fully understand this definition, a distinction needs to be made between the Personal Learning Network (PLN) and the closely related term, the Personal Learning Environment (PLE) as the two terms are often used interchangeably when, in fact, they refer to two separate conceptual models.

A Personal Learning Environment (PLE) can be thought of as the ecosystem that enables a PLN. A PLE represents

“the tools, artefacts, processes, and physical connections that allow learners to control and manage their learning” (Couros, 2010, p. 125).

Using this distinction, Twitter, along with other ICT’s, are tools of the PLE that enables interactions with a PLN. These other ICTs are significant as the PLN is not limited to interactions on Twitter alone and encompass not only other ICTs, but also face-to-face and non-ICT mediated interactions.

The other ICT’s  that are often used alongside Twitter can be divided into three broad categories; technologies used to enhance, extend, view, or manage Twitter data, technologies that are used in conjunction with Twitter, and technologies that are used independent of Twitter.


  1. Technologies used to enhance, extend, view, or manage Twitter data: Twitter extensions are tools that specifically enhance, extend, view, or manage Twitter data. This category can further be divided into three subcategories;
    1. technologies which participants use to view and manage the Twitter data stream (Tweetdeck and HootSuite),
    2. technologies that participants use to repurpose or modify Twitter data (such as, Packrati,The Tweeted Times), and
    3. technologies that are used to search Twitter data.
  2. Technologies used in conjunction with Twitter: Technologies in this category are tools that can be used independent of Twitter, but are often use in conjunction with Twitter, such as  blogs, social bookmarking applications (Delicious and Diigo), and collaborative tools (Google Docs). For example, Twitter itself is not a collaborative platform in that participants do not use it to collaboratively create a tweet. However, Twitter is often used in conjunction with Google Docs, a collaborative document authoring application, to help facilitate the creation of a shared resource among the PLN.
  3. Technologies used independent of Twitter, but may also be used for PLN activities. Other technologies that are used independently of Twitter. Examples are Facebook, LinkedIn, forums and Ning.

This is not an exhaustive list of ICT’s used within a PLE, but a sample based on interviews with thesis participants. PLE = Personal Learning Environment; PLN = Personal Learning Network; Data = Technologies used to enhance, extend, view, or manage Twitter data; Conjunctive = Technologies used in conjunction with Twitter; Independent = Technologies used independent of Twitter, but may also be used for PLN activities

  1. Hi Clint, this post is a great resource, thanks. I'm wondering a few things, and hope you don't mind some questions: Based on the description of the PLE ("(PLE) can be thought of as the ecosystem that enables a PLN") shouldn't the PLN circle be inside the PLE circle in the diagram? Also, where would you put something like "language" in the diagram?

  2. Sounds like some kinda new liberal religion being spread throughout the cyber-space environment hoping to infect the future voters of America.{:
