Grade inflation under the threat of students’ nuisance: Theory and evidence

This study examines a channel, students’ nuisance, to explain grade inflation. “Students’ nuisance” is defined by “students’ pestering the professors for better grades.” This paper contains two parts: the game theoretic model and the empirical tests. The model shows that the potential threat of students’ nuisance can induce the professors to inflate grades. Ceteris paribus, a student is more likely to study little and to pester the professor for a better grade if: (1) the professor is lenient; (2) the studying cost is high; (3) the reward from pestering is high; (4) the cost of pestering is low.     

A Gentle Introduction to Bayesian Analysis: Applications to Developmental Research

Bayesian statistical methods are becoming ever more popular in applied and fundamental research. In this study a gentle introduction to Bayesian analysis is provided. It is shown under what circumstances it is attractive to use Bayesian estimation, and how to interpret properly the results. First, the ingredients underlying Bayesian methods are introduced using a simplified example. Thereafter, the advantages and pitfalls of the specification of prior knowledge are discussed. To illustrate Bayesian methods explained in this study, in a second example a series of studies that examine the theoretical framework of dynamic interactionism are considered. In the Discussion the advantages and disadvantages of using Bayesian statistics are reviewed, and guidelines on how to report on Bayesian statistics are provided.     

Getting immersed in teacher and student perspectives? Facilitating analytical competence using video cases in teacher education

The ability to analyze and understand classroom situations through the eyes of not only teachers but also students can be seen as a crucial aspect of teachers’ professional competence. Even though video case-based learning is considered to have great potential for the promotion of analytical competence of teachers (i.e., becoming immersed in student and teacher perspectives as well as applying conceptual knowledge to better understand classroom situations), only a few studies have investigated the effects of corresponding instructional support. This empirical field study examines the effects on analytical competence of two types of instructional support—hyperlinks to multiple perspectives and hyperlinks to conceptual knowledge—by using a 2 × 2 factorial design in a computer-supported video case-based learning environment inspired by cognitive flexibility theory and participatory design. The study examines collaborative learning processes to discover what specific kind of instruction may help to counteract some of the known deficits of case-based learning and teacher thinking, such as limited perspective-taking. From a participatory design point of view, training novices to become immersed in teacher and student perspectives can be considered as an alternative for direct involvement of teachers and students in the design process. The study was realized as a four-day university course for pre-service teachers (N = 100). ANCOVAs of learning processes (small-group discussions) and outcomes (written case analyses) provide evidence that both types of instructional support (i.e., hyperlinks to multiple perspectives and conceptual knowledge) are beneficial. In particular, hyperlinks to multiple perspectives affected small-group case discussions and written post-tests as they led to increased immersion (i.e., perspective-taking). Hyperlinks to conceptual knowledge furthered the application of this knowledge, especially in the written post-tests. Implications for teacher education, participatory design, and further research are discussed.     

Phases of Mediatization

As election campaigns changed substantially in Western countries, it is generally hypothesized that this change in campaign communication is rooted in a revolution in communications, with the media rejecting its former role as mere transmitters and becoming a major actor in the campaigning process. Regarding the analysis of the “mediatization of politics”, Strömbäck presented a four phases model which offers a way to explore such a process in an explicit and systematic fashion. The resulting struggle between political parties and the media over who shall control the agendas of campaigns forces politicians to adapt to and, finally, to adopt media logic. By operationalizing these four phases in order to allow for empirical research, we investigated the roles of the news media and the political parties in Austrian campaign communication in the last four decades. Taking the agenda-setting power as an indicator for changes in this relationship, our study is based on the concepts of agenda-building and policy agenda-setting as extensions of the agenda-setting model. To establish party and media agendas, a content analysis was conducted on news releases of all Austrian parliamentary parties, the main evening newscasts of all Austrian broadcasters, as well as the political coverage of two quality papers and two major tabloids during the “hot phase” of the campaign. For examining the “struggle over agendas”, a time-series cross-section design (including data on 20 different policy dimensions) was applied. First results are based on the analysis of five election campaigns in 1970, 1983, 1990, 1999, and 2008.     

Climate change education: quantitatively assessing the impact of a botanical garden as an informal learning environment

Although informal learning environments have been studied extensively, ours is one of the first studies to quantitatively assess the impact of learning in botanical gardens on students' cognitive achievement. We observed a group of 10th graders participating in a one-day educational intervention on climate change implemented in a botanical garden. The students completed multiple-choice questionnaires in a pre-post-retention test design. Comparing the test scores revealed a significant short-term knowledge gain as well as a long-term knowledge gain. Consequently, our results show the potentials of botanical gardens as effective learning environments, and for complementing formal school-based learning settings regarding climate change education.
