Course Management Systems
CMS Strengths
- Simple, consistent, and structured Integration with student information systems (SISs) so student rosters are automagically populated in courses
- Private and secure (i.e., FERPA compliant)
- Tight tool integration (e.g., quiz scores populated in gradebooks)
- Supports sophisticated content structuring (e.g., sequencing, branching, and adaptive release)
CMS Weaknesses
- As it is widely implemented, the CMS is time-bound (i.e., courses go away at the end of the semester)
- Teacher, rather than student, centric
- Courses are walled off from each other and from the wider Web, thereby negating the potential of the network effect
- Limited opportunities for students to "own" and manage their learning experiences within and across courses
- Rigid, non-modular tools
- Interoperability challenges and difficulties (significant progress is being made on this front, but the ability to easily move data in and out of the CMS and to plug in alternative tools to replace or enhance native tools remains to be seen)
PLN Strengths
- Almost limitless variety and functionality of tools
- Customizable and adaptable
- No artificial time boundaries remains "on" before, during, and after matriculation
- Open to interaction and connection with persons without regard to their official registration in programs or courses
- Easily sharable with others both inside and outside of courses, programs, and institutions
- Student-centric (i.e., each student selects and uses the tools that make sense for their particular needs and circumstances)
- Compilable via simple technologies like RSS
PLN Weaknesses
- Complex and difficult to create for inexperienced students and faculty members
- Potential security and data exposure problems FERPA issues abound
- Limited institutional control over data
- Absent or unenforceable SLAs no ability to predict or resolve Web application performance issues, outages, or even disappearance
