Online Collaborative Learning Theory (Harasim)

• Constructivist Theories, Learning Theories & Models, Media & Technology Theories • 0

Summary: Online collaborative learning theory, or OCL, is a form of constructivist teaching that takes the form of instructor-led group learning online. In OCL, students are encouraged to collaboratively solve problems through discourse instead of memorizing correct answers. The teacher plays a crucial role as a facilitator as well as a member of the knowledge community under study.

Originators and Key Contributors:

Linda Harasim, professor at the School of Communication at Simon Fraser University in Vancouver, developed online collaborative learning theory (OCL) in 2012[1]from a theory originally called computer-mediated communication (CMC), or networked learning[2][3][4].

Online Collaborative Learning Theory (Harasim)

Core Design Principles of OCL

According to Harasim, there exist three phases of knowledge construction through discourse in a group:

  1. Idea generating: the brainstorming phase, where divergent thoughts are gathered
  2. Idea organizing: the phase where ideas are compared, analyzed and categorized through discussion and argument
  3. Intellectual convergence: the phase where intellectual synthesis and consensus occurs, including agreeing to disagree, usually through an assignment, essay, or other joint piece of work.

The end result is the Final Position, although a learner is never truly finished generating, organizing, and synthesizing ideas, and continues those processes at progressively deeper levels. Harasim believes that the teacher is critical to this knowledge construction, not only through facilitating the process and providing resources to the group, but also through ensuring that the core concepts and practices of the subject domain are fully integrated. The teacher is here understood to be a representative of the knowledge community or subject domain under study.

The following diagram by Harasim (2012), Figure 6.3, p. 95 illustrates this process:

OCL Versus Traditional Teaching Models

OCL, like many other online teaching models, operated in an environment that is asynchronous and place-independent. Students are typically free to engage in class discussions on their own time (up to a point) and can log on anywhere they have internet access. Where the OCL model might differ from other models, however, is that discussion is seen as central to learning, and textbooks and other materials as supplementary. This differs from traditional online courses, where readings might be the primary material, and discussions secondary. Students in traditional online courses might exhibit the tendency to forego discussion, which they see as extra work outside of what they will be graded for.

In a keynote presentation to the Brazilian Association of Distance Education in 2006, Harasim noted that usage patterns in virtual classrooms practising OCL saw students sending about 85% of messages, versus instructors in face-to-face learning taking up 80%+ of airtime. The distribution of communications was also found to be more equitable, with fewer outliers than in face-to-face learning. Another shift was in traditional student and teacher roles. In OCL classrooms, the teacher’s role shifted from being that of a provider/entertainer to being more of a facilitator as students took more responsibility for the learning process and for generating discourse.

Strengths and Weaknesses of OCL

Two main strengths include:

  • On par with college classrooms.  Online collaborative learning can promote deep learning and encourage discussions at the level of, if not higher than, discussions found in face-to-face campus classrooms. The asynchronicity that OCL offers as well as its other benefits outweigh any downsides, like lack of physical cues.
  • High-level skill development.  OCL supports high-level skills such as critical thinking, analytical thinking, synthesis, and evaluation.

Two weaknesses of OCL include:

  • Hard to scale. OCL requires highly skilled instructors with a deep level of knowledge in their field, and students must be limited in order for discussions to be effective.
  • Not as friendly to science and engineering disciplines. Because OCL lacks an inquiry-based or problem-based approach, it is less accommodating as a structure for faculty in the science and engineering fields, though it would not be impossible to combine OCL with such approaches.
