Teacher educators' collaboration plays an important role in the improvement of teacher education. Many studies in educational research focus on collaboration from 1 particular perspective. A focus on 2 perspectives, a qualitative (focusing on collaborative activities) as well as a quantitative (focusing on relations) perspective, and relating both perspectives, can add to our knowledge. Data were collected in 3 subject departments of a teacher education institute. Findings indicated that educators' collaborative networks inside the departments could gain from more coherent and dense relations, and that key players were important to support and sustain collaboration. Both perspectives were mildly related, correlations were found for "degree" and "information" (r = 0.31, p < 0.05), "degree" and "joint work" (r = 0.38, p < 0.01), and "reciprocity" and "joint work" (r = 0.33, p < 0.05), no correlations were found for "degree" or "reciprocity" and "discussing." At the department level, only mathematics showed significant correlations. Results indicated that, in further research, qualitative aspects as well as quantitative aspects should be included.
