Although previous meta-analyses have indicated a connection between inquiry-based teaching and improved student learning, the type of instruction characterized as inquiry based has varied greatly, and few have focused on the extent to which activities are led by the teacher or student. This metaanalysis introduces a framework for inquiry-based teaching that distinguishes between cognitive features of the activity and degree of guidance given to students. This framework is used to code 37 experimental and quasiexperimental studies published between 1996 and 2006, a decade during which inquiry was the main focus of science education reform. The overall mean effect size is .50. Studies that contrasted epistemic activities or the combination of procedural, epistemic, and social activities had the highest mean effect sizes. Furthermore, studies involving teacher-led activities had mean effect sizes about .40 larger than those with student-led conditions. The importance of establishing the validity of the treatment construct in metaanalyses is also discussed.

This meta-analysis summarizes teaching effectiveness studies of the past decade and investigates the role of theory and research design in disentanglingKEYWORDS: research design, meta-analysis, models of teaching and learning, process-product model, student learning, teaching effectiveness. This meta-analysis summarizes studies of the past decade that have investigated the effects of teaching on student learning. Thus, the focus is on the components of teaching in classrooms and their effects on student learning. One reason for conducting this meta-analysis in this time period was that recent models of teaching and learning should have influenced the findings of empirical studies. Consequently, prior meta-analyses needed to be updated. The second and equally important reason was to use meta-analysis to address potentially conflicting findings among studies.Accordingly, we based the meta-analysis on recent models of teaching and learning and distinguished among research designs. Thus, by being explicit about

Professional vision has been identified as an important element of teacher expertise that can be developed in teacher education. It describes the use of knowledge to notice and interpret significant features of classroom situations. Three aspects of professional vision have been described by qualitative research: describe, explain, and predict classroom situations. We refer to these aspects in order to model professional vision. We developed a video-based instrument to empirically test the model. The results show that our measure to assess aspects of professional vision differentiates between description, explanation, and prediction. The study provides insight into the structure of professional vision, allowing us to conceptualize it theoretically and discuss the targeted use for teaching and formative assessment of preservice teachers.

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.

We propose a conceptual framework which may guide research on fostering diagnostic competences in simulations in higher education. We first review and link research perspectives on the components and the development of diagnostic competences, taken from medical and teacher education. Applying conceptual knowledge in diagnostic activities is considered necessary for developing diagnostic competences in both fields. Simulations are considered promising in providing opportunities for knowledge application when real experience is overwhelming or not feasible for ethical, organizational or economic reasons. To help learners benefit from simulations, we then propose a systematic investigation of different types of instructional support in such simulations. We particularly focus on different forms of scaffolding during problemsolving and on the possibly complementary roles of the direct presentation of information in these kinds of environments. Two sets of possibly moderating factors, individual learning prerequisites (such as executive functions) or epistemic emotions and contextual factors (such as the nature of the diagnostic situation or the domain) are viewed as groups of potential moderators of the instructional effects. Finally, we outline an interdisciplinary research agenda concerning the instructional design of simulations for advancing diagnostic competences in medical and teacher education.

The development of professional vision is a strongly knowledge-guided process. In line with their content and aims, university-based courses can enhance teaching-relevant knowledge for teacher candidates.
