Academic self-concept (ASC) is characterized by the dual nature of stability and change. That is, students strive for consistency in their self-concept but also receive achievement feedback that leads to changes in ASC. Only a few previous studies have scrutinized the stability of ASC. The STARTS model (Stable, AutoRegressive Trait, and State)…

Previous research provides evidence that ratings from students and external observers can deliver reliable and valid measures of teaching quality. However, there is still a lack of research on how stable these measures are across time and classes, which is particularly important when they are used for evaluations. We addressed this issue in 3…

Despite the fact that grade retention is now seen as controversial in many quarters, it remains common practice in numerous countries. Previous research on the effects of grade retention on student development has, however, generated ambiguous results, particularly in terms of motivational outcomes. This ambiguity has been attributed in part to a…

Enjoyment is one of the most relevant and frequently experienced discrete emotions for both teachers and students in classroom learning contexts. Based on theories of emotion transmission between interaction partners, we propose a reciprocal effects model linking teachers' and students' enjoyment in class. The model suggests that there are…

Using German data, we examined the effects of one specific type of acceleration--grade skipping--on academic performance. Prior research on the effects of acceleration has suffered from methodological restrictions, especially due to a lack of appropriate comparison groups and a priori measurements. For this reason, propensity score matching was…
