Changes In Science Classrooms Resulting From Collaborative Action Research Initiatives

(Doctoral Dissertation Abstract)

Collaborative action research was undertaken over two years between a Korean science teacher and science education researchers at the University of Iowa. For the purpose of realizing science learning as envisioned by constructivist principles, Group Investigations were implemented three or five times per project year. In addition, the second year project enacted Peer Assessments among students.

Student perceptions of their science classrooms, as measured by the Constructivist Learning Environment Survey (CLES), provided evidence that the collaborative action research was successful in creating constructivist learning environments. Student attitudes toward science lessons, as examined by the Enjoyment of Science Lessons Scale (ESLS), indicated that the action research also contributed to developing more positive attitudes of students about science learning.

Discourse analysis was conducted on video-recordings of in-class presentations and discussions. The results indicated that students in science classrooms which were moving toward constructivist learning environments engaged in such discursive practices as: (1) Communicating their inquiries to others, (2) Seeking and providing information through dialogues, and (3) Negotiating conflicts in their knowledge and beliefs. Based on these practices, science learning was viewed as the process of constructing knowledge and understanding of science as well as the process of engaging in scientific inquiry and discourse. The teacher’s discursive practices included: (1) Wrapping up student presentations, (2) Addressing misconceptions, (3) Answering student queries, (4) Coaching, (5) Assessing and advising, (6) Guiding students discursively into new knowledge, and (7) Scaffolding. Science teaching was defined as situated acts of the teacher to facilitate the learning process. In particular, when the classrooms became more constructivist, the teacher intervened more frequently and carefully in student activities to fulfill a variety of pedagogical functions.
Students perceived Group Investigations and Peer Assessments as positive in that they contributed to realizing constructivist features in their classrooms. The students also reported that they gained several learning outcomes through Group Investigations, including more positive attitudes, new knowledge, greater learning capabilities, and improved self-esteem. However, the Group Investigation and Peer Assessment methods were perceived as negative and problematic by those who had rarely been exposed to such inquiry-based, student-centered approaches.
