This is my response to cooperation or collaboration
We seek cooperation when “we want others to assist us in achieving our goals”. When teaching in a traditional face-to-face class, the teacher is seeking the cooperation of their students to maintain classroom discipline, to participate and contribute in the learning activities, and to complete the assessment tasks that would lead to the accomplishment of learning outcomes etc.
The students would collaborate with other students in working on the learning activities or student projects.
The same principles could be applicable when teaching in an online class, using Moodle Forum or Elluminate or Adobe online session. The teacher is seeking cooperation from the participants to participate and contribute to the session.
The participants may collaborate with other participants or teacher in working through the activities.

The “seeking” of cooperation is normally from one party (the teacher) to the others (students or educators). In this case, it is an outcome which results from one party complying with the requirements and expectations of the other party. Sometimes it requires negotiation of both parties, who may or may not be having the same degree of powers in the teaching or learning process.
In case of community networked learning, the teacher is seeking collaboration (working in partnership) with other teachers or community network members to achieve common and agreed goals. This is likely to happen in team or group projects in educational networks, or cross functional teams where parties would collaborate in solving problems.

Currently, I am working with Jenny Mackness and Roy Williams on a collaborative research project, and we collaborate in planning and conducting the research. We also cooperate with other members of the Community Network in sharing our research process, information and experience.
Another example is when teachers are cooperating with management in carrying out their administration duties or working on learning or research projects, while collaborating with other teachers in developing learning resources.
In case of mentoring, the mentor (teacher) is collaborating with the mentees (in partnership) to achieve the goals (likely more with the mentees goals, though it may also be negotiated goals agreed by both parties). The mentor is also seeking cooperation from the mentee to develop and implement the learning plan in the mentoring process.
Referring to the above cases, the relationship between one party – teachers (mentor) and the other party – students (mentees) will determine whether it is cooperation or collaboration or both.
The relationship may be complicated when there are so many factors which could affect the situations (differences in skills, experience, power, perceptions and attitudes). However, you could still analyse and possibly list these factors to understand the relationship between them, based on experience.
The situation is complex when we focus on the group of feelings or ideas that influence the people’s behaviour or mental attitudes. Feelings, emotions or ideas coming out of the interaction are often dynamic, emergent, and therefore unknown and unpredictable (and uncontrollable) to the participants. We would classify such interactions to be complex.
The emergent learning arising out of the interaction and communication would be complex due to the dynamic changes in the learning goals and teaching, learning strategies and emotions of the parties concerned.
So, in case of networks, I think the relationship between the “members” of the network would be complicated, and the feelings or ideas that influence the network members (nodes) would be complex due to the emergence arising from the interaction and communication.
In summary, I would suggest that complication and complexity both exist in networks. Both cooperation and collaboration would exist in complex networks with complicated relationships amongst their nodes or network members. Learning would also be complicated and complex in learning networks.
