In Germany, the final grade of a doctorate is significant for careers inside and outside the academic labor market. Particularly important is the highest grade--"summa cum laude." At the same time, doctoral grades are constantly subject to criticism. Thus far, however, neither German nor international studies have examined the…

Researchers are combining self-reports from mobile surveys with passive data collection using sensors and apps on smartphones increasingly more often. While smartphones are commonly used in some groups of individuals, smartphone penetration is significantly lower in other groups. In addition, different operating systems (OSs) limit how mobile data…

Student success and drop-out predictions have gained increased attention in recent years, connected to the hope that by identifying struggling students, it is possible to intervene and provide early help and design programs based on patterns discovered by the models. Though by now many models exist achieving remarkable accuracy-values, models…

This study employs a uniquely multi-factorial, large-scale design to investigate baseline differences and the effects of a singular outdoor educational program on environmental attitudes, knowledge and behavior among primary and secondary school students educated in four different countries. Statistical modelling approaches employed country of…

This paper evaluates the effects of a high school curriculum reform on students' probability to enroll at university and to choose a Science, Technology, Engineering or Mathematics (STEM) major. The reform increased the difficulty of graduating from high school by increasing the instruction time in core subjects and by raising the graduation…

Current higher education is characterized by a proliferation of distance education programs and by an increasing inclusion of nontraditional students. In this study we investigated whether and to what extent nontraditional students are particularly at risk for attrition (vs. graduating) from distance education programs. We conducted a secondary…

In the course of educational expansion, gender differences in access to higher education have decreased substantially in many European countries. In Germany women are currently over-represented in upper secondary education and more frequently attain a general qualification for university entrance. Despite those advantages, women still enrol in…

Students in Germany are tracked into different forms of secondary schooling based on teachers' recommendations. The literature shows that school tracking is largely affected by academic achievement levels, but neglects the influence of individual achievement growth. The authors used data from the Berlin study ELEMENT (N = 2242) to characterize…

The study investigated the frequency, themes, and attributions for significant regrets in a random probability sample of 3,917 German and Dutch nationals between the ages of 40 and 85 years. It was found that 14% did not have any regrets in spontaneous memory, and that this increased with the age of the respondents. With respect to mentioned…
