Level 3 characteristics are increasingly important for fingerprint identification, particularly when the fingerprints are problematic and lack level 2 details. In practice, no reliable visualization methods for level 3 features are transferred into a course for the general public, forensic students, or investigators. Our group has reported the…

This study examined the individual, class, and school level variability of the students' science achievement. It was hypothesized that there are school or teacher effects which contribute toward explaining achievement differences, besides the student level differences. Owing to the nested structure of the data in Trends in International…

Prior research has shown that greatest student achievement in sciences is attributed to "inquiry-based instructional approach", in which the goal of science teaching is nurturing attitudes and skills necessary for independent quest for scientific knowledge. While prior research has clearly demonstrated positive instructional effects of…

Empirical analysis of secondary biology classrooms revealed that, on average, 68% of teaching time in Germany revolved around processing tasks. Quality of instruction can thus be assessed by analyzing the quality of tasks used in classroom discourse. This quasi-experimental study analyzed how teachers used tasks in 38 videotaped biology lessons…

Background: The association between frequent use of certain instructional practices in mathematics and science and learning outcomes in schools in low-, medium-, and high-achieving countries is the focus of this study. It not only looks at teaching practices "that work" (positively associated with achievement) but whether they…
