    As computer technology evolves, both the need for knowledge workers and the pressure to increase the effectiveness of teaching with the help of ICT increase. Teaching of the skills needed by the knowledge workers requires new pedagogy, where instead facts and obedience the focus is on skills, independence and learning to learn. The use of ICT in education brings its own challenges to learning situations. Social constructivist computer supported collaborative learning (CSCL) is becoming a major challenger for the traditional teacher-centered learning. One of these methodologies is Progressive Inquiry, which is developed in Finland. Since the social constructive theory emphasizes the relations between learners more than the individuals' actions, research in this field must also take into account the interactions that occur in learning situations. While traditional psychological and pedagogical methods are not applicable, an old method of social sciences, SNA or social network analysis is designed specifically for the analysis of groups of people. Applications of SNA in psychology and collaborative learning are however few and preliminary, and no reliable evidence on the applicability nor useful results exist. The purpose of this study is to find out if SNA can be applied to this field of research. In this study SNA was used to analyze the learning situations of 23 classes in comprehensive and secondary schools that used Progressive inquiry. The results show that SNA can be applied to the study of CSCL, since the analysis produced preliminary measurements that were related to the quality of the course. The results are also in concordance with social constructivist theory: a course's usefulness increases as the several students write high quality messages and participate widely in different conversations.

    The study examines one case of students' experiences from the activity in a collaborative learning process in a networked learning environment, and explores whether or not the experiences explain the participation or lack of participation in the activities. As a research task the students' experiences in the database of the networked learning environment, participating in its construction, and the ways of working needed to build the database, were examined. To contrast the students' experiences, their actual participation in the building of the database was clarified. Based on actual participation, groups more active and more passive than average were separated, and their experiences were compared to each other. The research material was collected from the course Cognitive and Creative Processes, which was offered to studentsof the Department of Textile Teacher Education in University of Helsinki, and students of the Departments of Teacher Education Units giving textile education in Turku, Rauma and Savonlinna in the beginning of 2001. In this course, creativity was examined from a psychological and sosiocultural context with the aim of realizing a collaborative progressive inquiry process. The course was held in a network-based Future Learning Environment (Fle 2) except for the starting lecture and training the use of the learning environment. This study analyzed the learning diaries that the students had sent to the tutor once a week for four weeks, and the final thoughts written into the database of the learning environment. Content analysis was applied as the research method. The case was enriched from another point of view by examining the messages the students had written into the learning environment with the social network analysis. The theoretical base of the study looks at the research of computer-supported collaborative learning, the conceptions of learning as a process of participation and knowledge building, and the possibilities and limitations of network-based learning environments. The research results show, that both using the network-based learning environment and collaborative ways of studying were new to the students. The students were positively surprised by the feedback and support provided by the community. On the other hand, they also experienced problems with facelessness and managing the information in the learning environment. The active students seemed to be more ready for a progressive inquiry process. It can be seen from their attitudes and actions that they have strived to participate actively and invested into the process both from their own and the community's point of view. The more passive students reported their actions to get credits and they had a harder time of perceiving the thoughts presented in the net as common progression. When arranging similar courses in the future, attention should be paid to how to get the students to act in ways necessary for knowledge building, and different from more traditional ways of studying. The difficulties of students used to traditional studying methods to adapt to collaborative knowledge building were evident on the course Cognitive and Creative Processes.
