LinkedIn vs Facebook for finding a new job• Growing importance of internet on job-searcher’s
strategies (Fountain, 2005).• Job-search strategies ‘formal’, ‘informal’ and
‘direct application’.• Informal job-search strategies include the use of
personal contacts, such as relatives, friends and co-workers whom act as referrals and provide ‘inside’ information on job openings.
• Informal search saves on search costs.

and Knowledge Development, XX (XX), p. XX-XX.
School of Business and Economics
Theoretical framework I Strength of weak ties• Granovetter (1974): strength of a social relationship or tie
affects job-searchers by amount + quality of job-information.• A tie is defined as ‘weak’ when personal contacts see each
other ‘occasionally’.• Such a weak tie can have a bridging function.
H1. SNS members who have received information about job openings via their SNS have a greater amount of weak ties in their SNS than SNS members who have not received information about job openings via their SNS.

and Knowledge Development, XX (XX), p. XX-XX.

Theoretical framework II Structural Holes
• Burt (1992):individuals gain more from social networks as structural hole• Structural holes are those places in between networks where relations or bridges
are absent and links do not exist,
H2. SNS members who did receive information about job openings via their SNS have a higher network entrepreneur personality index than SNS members who have not received information about job openings via their SNS.

and Knowledge Development, XX (XX), p. XX-XX.

Theoretical framework III Social Capital Theory (Lin, 2001)Social Capital: value of the resources that off- or online social
network ties hold:
1. Embedded resources facilitate information flows reducing transaction costs to find job opportunities.
2. Social ties may influence recruiters who play a critical role in decisions involving the job searcher.
3. Social ties may be conceived by a recruiter as certification of social credentials.
4. Provides emotional support but also public acknowledgement of one’s accessibility to certain sources.
H3. SNS members who have received a job offer via their SNS hold higher levels of resources then SNS members who have not received a job offer via their SNS.

Thus….
• For LinkedIn members: close ties (b = 0.20) and weak ties (b = 0.18)
• The structural holes hypothesis is rejected in our sample.• Neither tie-strength nor network entrepreneurial personality
index good predictor for students• For non-managers, weak-ties (b = 0.44) significantly predict
receiving information about job openings• For managers it is primarily close ties (b = 0.27)
Thus use LinkedIn and your close contacts to find a new job ☺

1. Dynamics of community of learning are complex (De Laat et al. 2007; Ahuja et al. 2003)
2. Most community of learnings actually perform differently than anticipated (Alexander, 2006; Giesbers, Rienties, et al., 2009) De Laat & Lally, 2004; Schellens & Valcke, 2005, Rienties et al., 2009).
3. High degree of informal communication. Because of a lack of formal rules, procedures, clear reporting relationships, and norms, more extensive informal communication is required (Ahuja et al. 1999, Rienties et al., 2009)
4. How to establish team cohesiveness, identity and ego involvement (Van de Bossche et al., 2006)?
5. Role of learner complex (Williamson et al. 2006, Rienties et al., 2009, Tempelaar et al., 2009)
6. Role of teacher in community of learning complex (Anderson & Rourke, 2001), De Laat et al. 2007)
3. Common problems in community of learning learning
School of Business and Economics
4. Major Research findings• Effectiveness team problem solving is determined by how
well team members are communicating with each other (Jonassen & Kwon, 2001, Rienties et al., 2009)
• Barron (2003) found that successful teams are able to create a joint problem-solving space
• Focus of discourse should be broader than just cognitive perspectives (Arts, Gijselaers, & Segers, 2002; Garrison, Anderson, & Archer, 2000; Roschelle & Teasley, 1995; Van den Bossche, Gijselaers, Segers, & Kirschner, 2006)
• teams have to make an effort in order to establish a dual- problem space, where participants simultaneously contribute both to the content space as well as the relational space (Barron, 2003)

Study 1 Role of Motivation in CSCLSubjects• 100 participants were randomly assigned in six groups. • The six groups had an average of 13.66 members (SD= 2.16, range = 11-
17) per team. • The average age was 19 years and 45% of the learners were female.

Social interaction in week 1-6
Jonas, Veronica and Tutor 3 central in 6 weeks of discussions14 students have participated, 1 student does not participateSeveral students on outer ring of social interaction (Bernard, Felix, Philip, Christina, Elena, Sandra, Jonathan, Bart)
School of Business and Economics
METHOD: integrated multi-method approach
Individual contribution to discourse using Content Analysis• Content Analysis on social and cognitive discourse of Veerman & Veldhuis-Diermanse
(2001), whereby a distinction is made between non-task related (Veerman NTR: 1 planning; 2 technical; 3 social; 4 non-sense) and task-related discourse activity (Veerman TR: 5 facts; 6 experience/opinion; 7 theoretical ideas; 8 explication; 9 evaluation).
– Three coders independently coded all messages based on unit of meaning– Students posted 2307 messages of which 2075 (90%)were considered as codeable
(90%). – The Cronbach
alpha (α) 0.928, the Cohen’s kappa was 0.71, 0.71 and 0.68
Position of individual within team using Social Network Analysis• Degree of centralisation of each individual of all communication as well as higher
cognitive communication;• Size of ego density network of each individual.• Higher cognitive degree of centralisation using results CA• Higher cognitive size of ego density network using CA
Academic motivation Scale of Vallerand et al. (1992): • Three aspects of intrinsic motivation (IMTK, to know; IMTA, to accomplish; IMES, to
experience stimulation)• Four other scales of decreasing level of intrinsic, and an increasing level of extrinsic
motivation (EMID, identified regulation; EMIN, introjected regulation; EMER, external regulation; AMOT, amotivation).
– Response-rate 93%, Cronbach
alpha for the seven items ranged from .760 to .856– Learners who are high on intrinsic motivation relative to all other students as “intrinsically motivated learners”. – Learners who are relatively high on extrinsic motivation are labelled as “extrinsically motivated learners”. – Learner can have both high levels of intrinsic as well as extrinsic motivation.(90%).

Higher Cognitive Discourse in week 1-6: Who interacts with whom on a higher cognitive level?
Paul, Jonas and Chris central in higher cognitive discourse in week 1-611 students contribute to higher cognitive discourse, 4 students and 1 tutor do not.

Overall findings study 11. Large differences between students with respect
to amount and quality of discourse2. Differences in contributions explained (in part)
by motivation1. Intrinsically motivated students contribute
more to task-related communication2. Intrinsically motivated students have more
connections3. Intrinsically motivated students are more in
the center of the social network4. Extrinsically motivated students contribute
“on average” but lower on social contributions, which is important for group development (Barron, 2003)
5. Extrinsically motivated students are scattered throughout the network

Study 2 Increasing learning satisfaction with webvideoconference
• Cohort 1 as described above (82 participants in 6 groups)• Cohort 2:
– weekly videoconferences + discussion forums– 69 participants in 5 groups
Instruments• Academic Motivation Scale• Prior Expectations of the course• Perceived usefullness of course
– 33 questions of seven categories: assessment (four items), course design (six items); course materials (three items); goals and tasks (four items); group collaboration (five items); instruction by teacher (five items); and learning satisfaction (five items).
