A category-based video-analysis of students' activities in an out-of-school hands-on gene technology lesson

Abstract: Our research objectives focussed on monitoring (i) students' activities during experimental teaching phases in an out-of-school gene technology lab; (ii) potential relationships with variables such as work group size and cognitive achievement. Altogether, we videotaped 20 work groups of A-level 12th graders (N = 67) by continuous recording of their lab-work phases. Subsequent analysis revealed nine categories characterizing the students' most relevant activities. Intra- and inter-observer objectivity as well as reliability scores confirmed the good fit of this categorization. Based on the individual time budgets generated, we extracted four clusters derived from students' prevalent activities. A cross-tabulation of two cluster analysis methods independently used showed a high level of agreement. Clusters were labelled as (i) 'all-rounders' (members of which applied similar portions of time to the main activities), (ii) 'observers' (members' dominating activity focussed on in-group
