“…Third, a quantitative indication of congruent test validity was deduced from applying the MC test in a Bachelor seminar that also focused on issues of classroom management (N = 74). Since previous studies showed that an increase in knowledge of class management is accompanied by an increase in both self-reported teacher self-efficacy in classroom management (Pfitzner-Eden, Thiel, & Horsley, 2014) and self-reported knowledge (Böttcher-Oschmann, Groß-Ophoff, & Thiel, 2018), we also studied these correlations. We used Pearson's Product Moment Correlation Coefficient to show that the MC test score was correlated with teacher self-efficacy in classroom management (r = .19) and two subjective change rating items ("In this seminar I have learned a lot about effective classroom management", r = .33; "In this seminar I did not learn anything really new about classroom management", r= -0.43).…”
