This study extends previous research on teachers' self-efficacy by exploring reciprocal effects of teachers' self-efficacy and instructional quality in a longitudinal panel study. The study design combined a self-report measure of teacher self-efficacy with teacher and student ratings of instructional quality (assessing cognitive activation, classroom management, and individual leaming support for students), and 2-level cross-lagged structural equation analyses were conducted. Data were collected from 155 German secondary mathematics teachers and 3,483 Grade 9 students at 2 measurement points. Although cross-sectional correlations between self-efficacy beliefs and characteristics of instruction were substantiated, the analyses only partially confirmed a causal effect of teachers' self-efficacy on later instructional quality. Instead, the analyses revealed a reverse effect of instructional quality on teachers' self-efficacy, with students' experience of cognitive activation and teachers' ratings of classroom management predicting teachers' subsequent seJf-efficacy. Our findings emphasize the importance of examining teachers' self-efficacy not only as a cause bu". also as a consequence of educational processes. Future research on teachers' self-efficacy should take a longitudinal perspective with varying time lags, identify possible mediator variables, and consider other aspects of teacher competence beyond self-efficacy when examining the effects of instructional quality.

Simulation-based learning offers a wide range of opportunities to practice complex skills in higher education and to implement different types of scaffolding to facilitate effective learning. This meta-analysis includes 145 empirical studies and investigates the effectiveness of different scaffolding types and technology in simulation-based learning environments to facilitate complex skills. The simulations had a large positive overall effect: g = 0.85, SE = 0.08; CIs [0.69, 1.02]. Technology use and scaffolding had positive effects on learning. Learners with high prior knowledge benefited more from reflection phases; learners with low prior knowledge learned better when supported by examples. Findings were robust across different higher education domains (e.g., medical and teacher education, management). We conclude that (1) simulations are among the most effective means to facilitate learning of complex skills across domains and (2) different scaffolding types can facilitate simulation-based learning during different phases of the development of knowledge and skills.

The present study investigates teacher diagnostic skills when observing student engagement and inferring to underlying student characteristic profiles. Five student profiles as empirically determined in previous studies are selected: three incoherent (overestimating, uninterested, and underestimating) and two coherent (strong and struggling) profiles. Teacher professional vision and underlying assumptions about processes of noticing and reasoning about the chosen diagnostic situation serve as a conceptual basis. In the empirical study (N = 41 participants), it is investigated to what extent expert and novice teachers differ with regard to judgment accuracy of underlying student profiles, observed student cues used for judgment, and teacher gaze as perceptual indicator. The study task involved observing a video clip and diagnosing five marked students based on their underlying profiles. First, findings of the study suggest that expert teachers are more accurate in judging incoherent profiles compared to novices. Second, both novices as well as experts state valid behavioral cues when inferring from student engagement to underlying student profile. Third, experts spend more teacher gaze on student profiles which might need adaptive pedagogical action (struggling, underestimating, uninterested student). The study provides first evidence on teacher gaze during the professional task of diagnosing individual students in the process of teaching. Regarding the conceptual model of teacher professional vision teacher gaze can serve as an additional operationalization of the noticing component of teacher professional vision.
