in computer-supported collaborative learning
one of current methods of application of sna study of computer-supported collaborative learning (cscl). when applied cscl, sna used understand how learners collaborate in terms of amount, frequency, , length, quality, topic, , strategies of communication. additionally, sna can focus on specific aspects of network connection, or entire network whole. uses graphical representations, written representations, , data representations examine connections within cscl network. when applying sna cscl environment interactions of participants treated social network. focus of analysis on connections made among participants – how interact , communicate – opposed how each participant behaved on or own.
key terms
there several key terms associated social network analysis research in computer-supported collaborative learning such as: density, centrality, indegree, outdegree, , sociogram.
density refers connections between participants. density defined number of connections participant has, divided total possible connections participant have. example, if there 20 people participating, each person potentially connect 19 other people. density of 100% (19/19) greatest density in system. density of 5% indicates there 1 of 19 possible connections.
centrality focuses on behavior of individual participants within network. measures extent individual interacts other individuals in network. more individual connects others in network, greater centrality in network.
in-degree , out-degree variables related centrality.
in-degree centrality concentrates on specific individual point of focus; centrality of other individuals based on relation focal point of in-degree individual.
out-degree measure of centrality still focuses on single individual, analytic concerned out-going interactions of individual; measure of out-degree centrality how many times focus point individual interacts others.
a sociogram visualization defined boundaries of connections in network. example, sociogram shows out-degree centrality points participant illustrate outgoing connections participant made in studied network.
unique capabilities
researchers employ social network analysis in study of computer-supported collaborative learning in part due unique capabilities offers. particular method allows study of interaction patterns within networked learning community , can illustrate extent of participants interactions other members of group. graphics created using sna tools provide visualizations of connections among participants , strategies used communicate within group. authors suggest sna provides method of analyzing changes in participatory patterns of members on time.
a number of research studies have applied sna cscl across variety of contexts. findings include correlation between network s density , teacher s presence, greater regard recommendations of central participants, infrequency of cross-gender interaction in network, , relatively small role played instructor in asynchronous learning network.
other methods used alongside sna
although many studies have demonstrated value of social network analysis within computer-supported collaborative learning field, researchers have suggested sna not enough achieving full understanding of cscl. complexity of interaction processes , myriad sources of data make difficult sna provide in-depth analysis of cscl. researchers indicate sna needs complemented other methods of analysis form more accurate picture of collaborative learning experiences.
a number of research studies have combined other types of analysis sna in study of cscl. can referred multi-method approach or data triangulation, lead increase of evaluation reliability in cscl studies.
qualitative method – principles of qualitative case study research constitute solid framework integration of sna methods in study of cscl experiences.
ethnographic data such student questionnaires , interviews , classroom non-participant observations
case studies: comprehensively study particular cscl situations , relate findings general schemes
content analysis: offers information content of communication among members
quantitative method – includes simple descriptive statistical analyses on occurrences identify particular attitudes of group members have not been able tracked via sna in order detect general tendencies.
computer log files: provide automatic data on how collaborative tools used learners
multidimensional scaling (mds): charts similarities among actors, more similar input data closer together
software tools: quest, samsa (system adjacency matrix , sociogram-based analysis), , nud*ist
