This is a resource on communities of practice and their positive impact on organizational development and group work. It highlights the work of Jean Lave and Etienne Wenger. It breaks down the 3 elements that differentiate a community of practice from other groups/communities and how knowledge is generated in a community. Situated learning is the model of learning that is explained as taking place in these communities of practice.

This article gives a short history of Communities of Practice and goes on to explain what they are. It is easy to read and understand as It explains what CoP are and what they are not.

Detailed article that describes the communities of practice philosophy that Jean Lave and Etienne Wenger developed the in the late 80's that proposes learning comes from the social interactions in our daily lives. The article further explains how the interactions with various groups causes the learning, whether it is as a core member or a bystander.

I really liked this article because as an educator it spoke to what I believe in. Learning does not only take place in the educational setting of a school, but it also takes place outside of that environment. Learning is social, it's physical, it's interactive, it's communicating. There are so many different ways to learn and therefore people never stop learning. It states that communities of practice are all around us and most of the time we are involved in many of those groups at the same time.

Lave and Wenger discuss communities of practice covering many topics such as the characteristics and the relationships. EDTECH543 Communities of Practice

This article discusses Jean Lave and Etienne Wenger, who proposed that "learning involved a process of engagement in a 'community of practice'." They discuss the idea of learning as being a social experience rather than an individual one, and that people are typically involved in a number of communities of practice. The characteristics of communities of practice are described, as well as situated learning.

This article clearly articulates what communities of practice are, examples of each (which I find the most interesting as it makes a very clear connection to what we know), and three main components. The three distinguishable ideas show how communities of practice are different than random groups. I like their ideas of these groups occurring over time around things thst matter to people. #EDTECH543

This source discusses communities of practice and how they can be either formal or informal. Members of a community of practice are in an organized group centered around a shared idea. Communities of practice allow connectivity because learners make connections with each other as resources to acquire knowledge when needed.

I learned about different definitions or explanations of communities of practice and how the learning happens by means of communities of practice is connected to situated learning. I also learned about different characteristics of communities of practice and how these characteristics are interconnected. I learned in detail about how the concept of communities of practice is aligned with the concept of situated learning. I enjoyed reading the examples and learning how communities of practices change over time.

In CoPs, connections are being made. Everyone is working together to get everything that they need. I think that the main focus of this descibres the aspects of collaboration and why it is so important with CoPs. CoPs is related to situated learning and that is something new that I learned.

"Communities of practice are formed by people who engage in a process of collective learning" A COP is joining in mutual activities.

3 crucial elements that make a COP: Domain, Community, and Practice. A domain is a common interest among members. A community means that members engage in activities and discussions and share information to help one another. Members practice by sharing tools and resources.is something that individuals do.

Excellent article that explains the characteristics of CoPs and how CoPs can be used in many aspects of life (both personally and professionally). This is the first article I have found that references "situational learning" as part of CoPs. The idea that learning is a social process and that we learn more from collaboration than we do independently seems to support the use and development of CoPs. Lave and Wegner illustrate that theory in the article by using examples from real-life situations.

This article really talks about the details of CoPs without going into the how-tos that many others do. I appreciate how foundational it starts- even pointing out that learning was initially thought of as an individual activity and how that has evolved. Situated learning is discussed as it is beneficial for learners to not just learn by hearing or doing, but by learning to talk about what they are doing.

Ariana, I loved how this article provided such great information and details.I also appreciate knowing the background of where foundations start. Thanks for the share!

This article gives a very detailed explanation of communities of practice. The author traces the term to its origins to Lave and Wenger. Definitions of the characteristics of communities of practice are defined. Both Lave and Wenger claim that learning requires communities of practice which create authenticity beyond models to be applied to real situations

Article does a great job of explaining where connectivism came from and how it will continue to advance forward just as society if doing currently. We will continue to learn and mold our understandings based off of the connections we are making through a collaborative network.

This article provides a balanced view of the arguments concerning the role of connectivism in the field of education. The authors have done a nice job of differentiating the types of theories and their roles in practice. Perhaps the strongest features of the entire article is the discussion on connectivism as it applies to the use of technology. I appreciated their description of the theory as a connecting piece between some of the more established learning theories and the new technological landscape that characterizes our learning environment. Excellent article - thanks for sharing!

This article by Duke, Harper and Johnston is a detailed analysis of connectivism as a learning theory. Not only is technology discussed as how it's applied to this theory, but there is also discussion of learning theories and instructional theories in general. It is also a valuable read because it explains how this theory can or should not be applied to all students or content.

This source gives a good description as connectivity and connectivity as a learning theory, and it also discusses the argument that connectivity is not a learning theory. It ends by talking about connectivity and its integration with technology and online learning.

This article from Kaplan University explains the importance of connectivism in a digital age. They reference George Siemens and Stephen Downes and their research behind connectivism as a learning theory. They examine connectivism as a learning theory, and explain how the learner is at the center and designs their own path, essentially making their own learning.

This article discusses Connectivism and the debate over whether it should be considered as a learning or instructional theory or as a pedagogical view. The role of Connectivism in the use of technology in education is also discussed.

I really liked this article mainly because they clearly explained the difference between learning theories vs. instructional theories. I think that was useful in their conclusion that connectivism really is more of a tool to be used in the learning process rather than a complete learning theory.

This article discusses the validity of Connectivism as a learning theory. It gives the very straight-forward definition as "social learning that is networked." The discussion of the importance of the Connectivism theory in today's ever increasing technical classroom is quite engaging. It has also forced educators to look at what is being done in digital education and rethink, debate, and philosophize over how each part fits.

In this article, Duke, Harper, and Johnston discuss whether connectivism is a learning theory or an instructional theory. They begin by discussing the differences between learning theories and instructional theories. A learning theory should explain how learning occurs, while an instructional theory should explain how best to achieve the learning goals. The authors summarize connectivism as "social learning that is networked" (2013, p. 6). What a person knows is not as important as the connections the person makes that will allow further know,edge and growth. Everyone feeds into the systems of knowledge and receives greater knowledge as a result. This knowledge can be held by people, societies, or machines. Basically, everyone learns through personal learning networks. These learning networks allow people to learn through collaboration rather than by having to experience everything for themselves. Being able to tap into a large amount of knowledge allows people to understand patterns they might now otherwise see. While there are several arguments against connectivism as a learning theory, the authors argue that connectivism can be useful as an "instructional guide or theory" (2013, p. 9) to develop behaviorism, cognitivism, or constructivism for "application to a globalized and networked world." The authors conclude that connectivism is useful in the learning process or curriculum planning, but that it is not a "standalone learning theory" (2013, p. 10).

This talks about how connectivism takes elements from behaviorism, cognitivism, and constructivism. It discusses connectivism as a learning theory and how the use of technology ties into it.

This article puts a focus on the debate if connectivism is "a learning theory or instructional theory or merely a pedagogical view." Instructional theory has major elements that are discussed in this article and connectivism is analyzed to see if it in fact, is a learning theory. The author recognizes that the debate will last a long time but the fact that connectivism is valuable in the educational setting will prevail. Technology is a major factor of its success. This article convinced me of the importance of allowing my students more access to technology for educational success.

The author of this article defines learning theories vs instructional theories, connectivism, connectivism as a learning theory, and connectivism and the use of technology. Connectivism was created as a learning theory for the digital age. Siemens and Downes came up with this theory because social learning can happen through networks. In today's world technology and advancements are changing rapidly, which in turn is providing new information quickly. Educators have had to embrace this new option of networks for knowledge use in the classroom. Connectivism can be used as a tool in the learning process for instruction or curriculum.

We are at a crucial point in history. By being educators, we must constantly be discussing and managing our definition of an educator's job. We must constantly be working through our philosophy base as new tools and ideas come to life.

This paper outlines connectivism and analyzes whether it should be considered a learning theory, instructional theory, or pedagogical view. I found this article interesting as it has a good discussion the differences between learning theories and instructional theories. The paper is critical of Connectivism as a learning theory, which I think is important as you consider how to use its principles in the classroom.

This article discusses a theory developed for the digital age by Siemens and Downes called connectivism. The theory has issued a debate over whether it is a learning theory, instructional theory, or a pedagogical view. In this article, the authors discuss learning in the digital age and how the theory of connectivism fits within the world today. There is a focus on connectivism being social learning that is networked.

This article discusses whether Connectivism is a learning theory or an instructional theory or a pedagogical view. A learning theory is not whether something is true or not but if it is useful for explaining behavior. An instructional theory must list procedures to enable learning by focusing on the overall structure of the learning material and how to achieve the most successful learning experience. Connectivism is social learning that is networked. It could be a learning theory as it states how a student learns through a network. Connectivism can be categorized as a tool to be used in the learning process and not a standalone learning theory.

I like this article because it gives teachers a clear definition of what a PLN and how to connect to one. I am new to using social networking professionally so I am interested in learning ways to connect to PLN that would benefit my classroom.

Thomas Whitby is an educator that I have followed on Twitter and consider a valuble member of my PLN. So it is fitting that I would include an article written by Mr. Whitby explaining the purpose of a PLN. Mr. Whitby explains that PLNs use social media and technology to collect, communicate, collaborate and create with like-minded individuals. Unlike traditional professional development sessions, PLNs can take place any time and anywhere through the use of the WWW. Each PLN is uniques and serves its own purpose and each member is a potential source of information. Mr. Whitby concludes his article with information on how to build a PLN and links to PLN resources.

This article gives the definition of a PLN and answers the question of why they are important. It also talks about potential barriers, this is important! It also has links to other resources for PLNs.

This blog post thoroughly defines PLNs, even addressing the debate over its acronym. Is it professional or personal learning networks? This post settles on a happy medium: personalized learning network. This entry goes beyond the definitions as it addresses both the barriers to PLNs and what can be gained from them. It also offers suggestions on how to build a PLN and helpful links.

@mskmjohnson Great article! I particularly like the focus on a CoP vs. a team and the practical information on maintaining a CoP

This in-depth overview discusses CoPs covers their roles in organizations like other articles, but it also talks about where the can be found and their differences than teams, businesses, networks, etc- offering a definition more by what it is not. The stages of development image helped me better understand the foundation of a CoP.

Etienne Wenger explains the importance of Communities of Practice. Wenger states that communities are everywhere and most people are involved in a community of practice. Communities of practice are different than a community of interest or geographical communities because of three elements. The three elements are what it is about, how it functions, and what capability it has produced. The community of practice can be within businesses, across business units, or even across company boundaries. All "communities of practice move through various stages of development characterized by different levels of interaction among the members and different kinds of activities."

Article by Wegner explaining CoPs that has a couple of great graphics of what it means to be in a CoP, how to develop them, and how they relate to organizations

I really like how this article connects the idea of CoP to things other than education. It is a 21st century skill that we can teach our students and have them continue to use even after their formal education is complete.

Sometimes we teachers get ourselves stuck on the idea that we are clearly the only profession out there in the world when we are researching topics like CoPs. However, this isn't the case, and I really appreciate that this resource outlines the idea of communities of practice as far reaching and for more than just teachers. It comes back to the community. Without the community, there is no practice.

This article goes beyond the basic definitions of CoPs as it provides where communities can be found and the importance of CoPs to organizations and offers suggestions to develop and nurture CoPs.

For me it is easy to think of CoPs in education but I liked looking at them in other organizations. Thinking about how to keep them going was interesting. Things like legitimizing participation seems obvious but can really make or break a CoP.

This article begins by describing three different communities of practice, but not how one would traditionally think of them. A "community of practice" for myself on a personal level would not necessarily have to be the other middle school teachers in my building, but could involve the elementary art teacher I am friends with. The more I read about these communities of practice the more they are sounding like "like-minded people who talk about stuff they have in common." There is a neat little graph describing five stages of development of these communities.

This page offers different wording and definitions of PLNs.

This article talks about Communities of Practice and how they differ from PLN. COP have a centralized theme, how they function depend on the sophistication and functionality of the group as a whole.

Essentially, that is what learning is all about! Lifelong learning is key for all individuals. One of the rewards of PLN's is developing lifelong peer friendships. Even if it is only in an online community! Great job!

A fabulous article that describes exactly what a PLN is & isn't. They define it as: "A network of trusted connections with whom an individual interacts (and learns from) on a regular basis." - Jane Hart. It stresses that while technology has advanced and changed PLN's they are mainly about the connections formed & relationships made. It describes a PLN as being "random" while a COP is more intentional & formal (since COP often share professional expertise).

This article describes what PLNs are and how they differ from PLEs. It also outlines the importance of PLNs for becoming a better teacher and connecting with others.

This particular article talks about how PLNs have layers, starting with the center layer. This includes a person's mentors and friends. The next layer are people or groups that are bound by common interests. The last layer are the experts and professionals that people look to in order to gain personal knowledge. This article also points that sometimes people get PLNs and CoPs mixed up. However CoPs take this one step further by having a profession/ professional interests in common. In other words, most Trekkies at ComicCon are not CoPs, but rather PLNs.

This resource defines PLNs and the benefits of today's learners connecting online with people of similar interests. However, the differentiating aspect of this article is actually the section titled "What a PLN is Not." In this section, PLNs and CoPs are compared and contrasted regarding purpose and structure with PLNs being less formal than CoPs. Additionally, this resource illustrates the difference between PLNs and PLEs, markedly stating that PLNs are a part of PLEs and that they house the virtual network and tools used to collaborate. Finally, this resource pulls on Connectivism to explain the importance of a PLN, citing the Connectivist principle of continued learning made possible through constantly updating networks of users.

Michelle, what an excellent resource! I was particularly interested where it explained that a PLN is not a PLE because I'm finding myself in my elementary understanding of these concepts mixing these up!

In EdTech504, I took particular interest in Connectivism Learning Theory and its relationship to information literacy. I think this article also portrays that, although I wish the relationship would have been more explicitly stated. Thanks for posting!

A brief blog post on connectivism and its implication and application to 21st century learning. Each of George Siemen's principles of connectivism are connected to a mode or practice of learning.

This blog post discusses Siemens core principles of connectivism and how it relates to education, and more specifically 21st century learning. The main purpose of this blog is to show how educators need to rethink the educational process and apply connectivism in the classroom.

I like that fact that this article breaks down principals of Connectivism into today's learning. The thing I take away from this article is that the Teacher is no longer the holder of information. Endless information is out there and our job as educators is to teach our children how to access the knowledge out there - making them life-long learners!

I liked this article and how it appears to break down Connectivism into what appears to be a "should do" list. What the educator should do in order to connect with the student and stay connected to resources.

This is an expansion of a previous blog by the author highlighting how connectivism can be applied to 21st century learning. Also reviews the impact of connectivism to teaching and learning applications.

I liked this article because it went into detail about the connecting nodes component of the theory. I think there is a whole lot of value in exploring the fringe topics or seemingly unrelated knowledge and seeing what happens when these "nodes of knowledge" are put together. It's modern design thinking coming into the world of learning and education.

This blog post breaks down Connectivism in the 21st century. Looking at students as digital natives and the impact this has on teachers, education and learning.

This blog post discusses the impact of Connectivism on education. Marquis lists the Seimen's seven principles of Connectivism and then goes on to explain how the principles can be meshed with 21st Century learning.

This webpage offers a few external links that are helpful in understanding the theory of connectivism. The author lays out the core principals for this theory and then explains in more detail additional principals that harden the foundation of connectivism.

This article summarizes Siemens article on Connectivism: A Learning Theory for the Digital Age. In this age where so much information is at our finger tips, it is the role of the teacher to help the learner access the best information and make sense of what they access. Dr. Marquis brings up a good point that there isn't much research to implement connectivism or what affect it actually has on learners.

This article is an outstanding review by Mark K. Smith of Jean Lave and Etienne Wenger's theories of social learning through communities of practice. It gives a great overview of the theoretical foundations as well as additional explanations of those theories.

This article outlines the theory and practice of communities of practice, and discusses the idea that learning is social and comes from of our experience of participating in daily life. The authors identify a variety of types of CoPs that all humans are engaged in, even if they are not formally identified as such. A CoP is defined along three dimensions: what it is about, how it functions, and what capabilities/resources it has produced. Also emphasized are the importance of the relationships formed between the people within the CoPs - hence, the community in CoP. Stemming from that, they extend the idea of CoPs to apply to the classroom culture and environment and discuss the need for educators to cultivate a similar idea to best facilitate learning among their students.

The point that I learned from this article is that communities of practice go beyond the acquisition of knowledge and skill. They build relationships where people within the community work together to share their skills, knowledge, and interests they have learned in order to complete new or more complex tasks. We learn best through active participation.

Articles like this one make it clear that we are actively involved in communities of practice every day, without even realizing it. This is largely due to the internet; now, if one needs to reach out to another person for advice on baking, for example, one can use online forums or message boards to connect to others in their community of practice. This was not possible before the internet, or at the very least it was difficult to accomplish so easily. I'm interested to learn a little more about what COPs might have looked like before the internet.

Learning is social and takes place by participating in daily life. Learning takes place situationally in communities of practice. These communities of practice exist all around us: home, work, school, etc. As we pursue our goals within our groups, learning occurs. Members off s community of practice (CoP) are united by common activities and by what they learn through participating in those activities. A community of practice is defined by three factors, "what it is about," "how it functions," and "what capability it has produced." For a community of practice to be effective, it needs to "generate and appropriate a shared repertoire of ideas, commitments and memories." There also need to be resources like documents, tools, procedures, and a shared vocabulary. The the developers of this theory, Jean Lave and Etienne Wenger, focused on the kinds of "social engagement" that caused learning to take place. People join groups and initially learn from the periphery. Eventually, they become more proficient through their participation as they move toward the center of the group. The situation in which the learning occurs has a significant effect on the learning.

After reading through this article, I kept coming back to this quote: "Rather than looking to learning as the acquisition of certain forms of knowledge, Jean Lave and Etienne Wenger have tried to place it in social relationships - situations of co-participation." These are ideas I try to integrate into my classroom on a day-to-day basis because healthy social relationships can enhance learning experiences due to students becoming vested in goals. Students are more willing to put their feet outside of the box, without fear of sharing and participating in these learning environments---and they become active inside members of these groups, rather than outside onlookers.

Edmodo is an LMS so I guess then all LMS would be PLN tools. I guess I never thought of them that way but they are. Ive used Edmodo once before to organize a project among faculty but have mostly used it with students.

Staggering number of teachers that are enrolled in Edmodo, which show how the education field truly embraces the concepts of communities of practice. The communities of practice idea has not fully been accepted into the USCG and I'm excited to work to create one.

The article is a comprehensive view of PLNs. It gives concrete examples of how to design and grow a PLN. By examining three widely used PlNs, it might encourage more teachers to begin a PLN. I appreciated the statement: Only the teachers who are continual learners [who] work to improve their practice, skills, and instructional strategies can successfully help others learn.

Being a teacher your PLN is so important to your growing and developing. This article really focus on that and how teachers us it. It also give example of other services that teachers can use that will increase their ability to find and use information form the internet,

Resourced by an edutopia article, I found this information to be both user friendly and helpful. Best of's, design tips, and aspects of PLNs that make people want to be active are included

The mention of RSS in this article is very helpful because it is such a simple way to keep track of all your networks. It keeps everything in one location so you only have to open one program to read it all!

This article explains the basic idea of personal learning networks, especially related to e-Learning. The author makes the argument that the education system needs to adapt the ideas behind personal learning networks in order to be successful in the future.

This article discusses the important trends in personal learning environments. It talks of its importance in life long learning, informal learning, the impact of different learning styles and how technology is playing a huge role in our education today,

This is paper written back in 2007 about PLNs. The author argues that PLN are the future of elearning because of the power they have to offer individualized learning and give the learner the opportunity to organize his/her own learning. That educational institutions cannot expect to simply recreate the same forms of learning used in tradition education online. rather that we must learn to adapt to the new and emerging technologies of ubiquitous computing and social software. Considering that this article was written 9 years ago, I found it to be extremely accurate and representative of PLNs today.

The article looks at personal learning environments and discusses the possibility that some form of PLE will be needed as part of the future of learning. It also discusses the need for changes in education to accommodate PLEs as current teaching methodology is out of date with how current students wish to learn.

This article pushes for a change in learning through Personal Learning Environments. This article recognizes that PLEs help to foster lifelong learning though providing multiple tools and resources to support the learning. It is argued that this learning does not have to be a formal, institutional learning, but can be informal which adapts for different styles of learning. A very interesting aspect of the article to me is the addressing of assessment and how the learning that has taken place through the PLE would be assessed. This primarily explains that evidence could be shown through artifacts and possibly an e-Portfolio. It later goes on to explain what a PLE would look like which include a copious amount of tools that one uses daily for learning. These tools primarily would be comprised of what is called social software connecting collaborators. The important take away from this article is that a PLE is not a tool to be implemented, but instead an approach for the use of a web of tools for learning and sharing creating a bridge between the learner and the world outside.

@kcastello Thanks for the article! I particularly like the distinction you made between PLEs as an approach, not a tool.

This site explains in plain terms communities of practice. For example, it explains that a community of practice is not just a club. It is a group of people who are committed to a certain domain of interest.

This was a concise, but well written overview of the definition of communities of practice.

Communities of practice are used across a variety of groups of people. According to Etienne Wenger, there are three characteristics that constitute a community of practice: domain, community, and practice. Communities of practice exist on small local scales, to worldwide networks. This allows people to share and obtain knowledge about common practices with others who are actively engaged in the same domain.

Allows the reader to determine the general guidelines to what a community of practice is. Cites examples ranging from artists seeking transformation to surgeons trying to discover new methods. The article is very simple, yet effective in describing a community of practice.

by Etienne Wenger CoPs are formed by people who are engaged and interested in common domains. These can be done in many domains as long as there is an underlying interest. CoPs provide a new way to learn from one another in a safe environment. All members take responsibility with their members to access knowledge while sharing new ideas.

In this article, Wenger provides a quick overview of what a Community of Practice is. I like how she discusses the three components of a CoP and gives an example of what is not considered a CoP in each component. She addresses that just because something is a community, doesn't make it a Community of Practice. She also discusses where the concept of a CoP is being applied. It is helpful to see that it is being applied in many different fields including: education, government, organizational design, and businesses.

This website, from the National Center for Dissemination of Disabilities Research, identifies 3 characteristics of strong communities of practice: the domain, the community, and the practice. It briefly identifies what makes COPs unique and identifies specific applications. There are additional links in the sidebar that provide more information about COPs and prompts for further research.

This article gives an overview as to what communities of practice CoP are. It describes the characteristics of CoP: domain, community, and practice. The article stresses that CoP are not just like-minded people, but they are where people can interact with others to learn with and from others. CoP rely on active participation. Sharing and learning are at the heart of CoP.

Provides a good, crisp explanation of CoP. This is more of a recap, but sometimes saying something in another way helps to get the point across better. What I particularly liked about this one is that it emphasizes how these communities interact based on a passion that they'd like to learn more about or to improve skills.

This article discusses communities of practice in a very understandable, clear way. It describes communities of practice as individuals working together in collaboration with a common goal, or passion, in mind. I feel that one of the most vital parts of my job as an educator is to collaborate with other teachers about best practices to use in the classroom. It was fun to read this informative article!

This is a great overview of Communities of Practice. I appreciate that it distinguishes between a community and a community of practice because "not every community is a community of practice." I also appreciate that it gives where the concept can be applied.

The article provides a definition of communities of practice and gives examples of these communities. It also gives the three "crucial" characteristics of communities of practice.

Wenger's excerpt focuses on a crucial aspect of CoPs - the difference between a community and a CoP. Wenger outlines the three characteristics of a CoP and the role each plays in executing a CoP. (1) The domain in a CoP is not just a group of people. It is a network of people with similar interests and commitment to the growth of that interest. (2) A community engages, shares, and collaborates in order to learn from one another. (3) The practice of a CoP involves creation. The members act as "practitioners" that develop and share over time and through continuous interaction.

This article discusses how the community of practice is a shared domain between its members or those who engage in the community. It also says not all communities are all communities of practice. To explain that, it lists the three important parts that help show it is a community of practice. It states those parts are the domain, the community, and the practice. With that, it explains that all three should be developed within the community itself.

The author of this article explains that a community of practice is more than just a community. Communities of practice have to have three elements. The three elements are the domain, the community, and the practice. The domain is a shared interest. The community is people engaging in joint activities and discussions while helping each other and sharing information. The practice is the members of practice are practitioners. Communities of practice are being applied in business, organizational design, government, education, etc. Communities of practice have become a learning system throughout the entire world. They help practitioners take responsibility for managing knowledge, create a direct link between learning and performance, and create connections without formal structures.

Kayden, what a great site and explanation of communities of practice. I particularly like the distinct description of what a community of practice is including what it is not!

This site gives an outline of three factors that make a community one of practice vs. a non-specific group of people. The domain, community, and practice all combine to create a community of practice. The site then goes to explain where the concept of a community of practice is applied furthering the idea of "practice," as well as why they are catching on in workplaces and organizations.

An introduction to and application for communities of practice.
