The Spiral of Violence: Equity of Violent Reprisal in Professional Wrestling and its Dispositional and Motivational Features

Though lacking empirical evidence, professional wrestling has been criticized for portraying excessive violence in harmful contexts. This study focused on the equity of violent reprisal perpetrated by liked versus disliked protagonists with socially sanctioned or unsanctioned motives. Results of a quantitative content analysis show that most violent interaction sequences were over-retributive. Violence that was not part of match competition was routinely initiated for normatively unsanctioned motives and showed predominant patterns of escalating violent retribution. These patterns held across perpetrator disposition. Thus, liked characters regularly aggressed for normatively unacceptable reasons. The consequences of these portrayals are discussed.     

The Effects of Ignoring a Level in Multilevel Analysis

Ignoring a level can have a substantial impact on the conclusions of a multilevel analysis. For intercept-only models and for balanced data, we derive these effects analytically. For more complex random intercept models or for unbalanced data, a simulation study is performed. Most important effects concern estimates and corresponding standard errors of the variance parameters at adjacent levels and of the coefficients of the predictors at the ignored and bordering levels. Therefore, we conclude that if the researcher is interested in a specific level, she/he should account for both the upper and lower level. Conclusions are illustrated using empirical data from educational research.     

Group incentives for teachers and their effects on student learning: a systematic review of theory and evidence

The effects of teachers’ group incentives on student achievement are examined by reviewing theoretical arguments and empirical studies published between 1990 and 2011. Studies from developing countries reported positive effects of group incentives on student test scores. However, experimental studies from developed countries reported insignificant effects. Some of the evidence appears to show a positive association between small group size of teachers and the effectiveness of group incentives. Still, it is uncertain whether the key to successful group incentives in teaching emanates from the incentive size, teacher group size, teacher intrinsic motivation, or type of incentive (rank type vs. non-rank type). Furthermore, most studies show that individual teacher incentives have positive effects unlike studies on group incentives. However, there is a lack of comparative studies of group incentives and individual incentives. We conclude that current empirical evidence has unclear policy implications and recommend additional experimental research.     

Some Conceptual Issues in Observed‐Score Equating

In spite of all of the technical progress in observed‐score equating, several of the more conceptual aspects of the process still are not well understood. As a result, the equating literature struggles with rather complex criteria of equating, lack of a test‐theoretic foundation, confusing terminology, and ad hoc analyses. A return to Lord's foundational criterion of equity of equating, a derivation of the true equating transformation from it, and mainstream statistical treatment of the problem of estimating the transformation for various data‐collection designs exist as a solution to the problem.     

Bias Corrections for Standardized Effect Size Estimates Used With Single-Subject Experimental Designs

A multilevel meta-analysis can combine the results of several single-subject experimental design studies. However, the estimated effects are biased if the effect sizes are standardized and the number of measurement occasions is small. In this study, the authors investigated 4 approaches to correct for this bias. First, the standardized effect sizes are adjusted using Hedges’ small sample bias correction. Next, the within-subject standard deviation is estimated by a 2-level model per study or by using a regression model with the subjects identified using dummy predictor variables. The effect sizes are corrected using an iterative raw data parametric bootstrap procedure. The results indicate that the first and last approach succeed in reducing the bias of the fixed effects estimates. Given the difference in complexity, we recommend the first approach.     

The use of keywords for delivering immediate performance feedback on teacher competence development

Literature shows that feedback that is specific, immediate and goal-oriented is effective on (pre-service) teachers’ performance. Synchronous coaching gives this kind of feedback. Due to immediateness of feedback, pre-service teachers can suffer from cognitive load. We propose a set of standardised keywords through which this performance feedback can be delivered – each keyword acts as a summary for the feedback message. The construction and the selection of the keywords is aimed at the reduction of message ambiguity, while at the same time a low level of cognitive load on the pre-service teacher must be maintained. An in vivo pilot-study with 40 respondents (pre-service teachers and their coaches) supported our hypothesis that usage of such sets of standardised keywords will mitigate the levels of ambiguity and cognitive load. These findings and other considerations for additional research using immediate performance are addressed.     

Development of an engineering identity in the engineering curriculum in Dutch higher education: an exploratory study from the teaching staff perspective

How do engineering students develop a professional identity during the course of the curriculum? What are the development mechanisms and important conditions? In an exploratory study among teachers the authors tried to find out whether the development of engineering identity can be understood by using the theoretical models of Ibarra and Sullivan. The results showed that the development of engineering identity is boosted during the internship in industry in the third year. Furthermore, the theoretical models could be recognised in the findings and four interaction types in internships, with significant differences in effect on identity development, could be identified if two dimensions were used: (1) industry supervisors’ perception of students; (2) the professional responsibility awarded. Some recommendations for curriculum improvement could be made; for example, introducing projects into the curriculum to stimulate identity development from the start. Further research is required on students’ preparation for internships.     

Different pathways towards dropout: the role of engagement in early school leaving

In this study, we examine the development of student engagement in relation to dropout. We focus on different growth trajectories of engagement between groups of students and on whether these trajectories lead to differences in the survival of the student. The development of behavioural and emotional engagement of 4063 graduates and 541 (11.7%) dropouts is examined from Year 7 to Year 12 and this development is linked to the probability of dropping out in each grade by means of a discrete-time survival mixture model. For emotional engagement, results point to a model with two different subgroups: one group starting at a high level of engagement and following a (relatively) stable pattern and the other group starting at a lower level of engagement and following a decreasing trend. For behavioural engagement, the results indicate that a three-class model showed the best fit: a high and (relatively) stable group, a high and decreasing group and a low and stable group. In terms of dropout, the unstable and low groups demonstrate a significantly higher probability of dropping out, as evidenced in the steep, declining survival curves. Different background variables are included to gain more insight into engagement and dropout, and to predict membership in the low and decreasing class.     

On strategies of educational innovation: Between substitution and transformation

The innovation of education seems to beself-evident. Boosted by a wide range of newtechnologies, educational institutes all overthe world are innovating their educationalsystems, in order to extend their services, toimprove their performances or to reduce costs.The apparent self-evidence of educationalinnovation hardly prompts the educational staffto reflect on the very idea of innovation andits consequences. This paper treats the basicprinciples that support the phenomenon oftechnology-induced educational innovation. Itaims to contribute to a better insight andunderstanding of its implications to anyoneengaged in education. It also aims to effect agrowing awareness of the premises on technologyand to support the right attitude to realiseimprovements in practice. The paper goes intostrategies of change, while discussing bothsubstitutional and transformational strategies.It explains its supposed differences byreferring to the philosophical frameworks ofJaspers, Heidegger and Borgmann. Starting fromBorgmann's ``devices paradigm', four principlesfor educational innovations are formulated,referring to the transparency and interactivityof educational technologies, the socio-culturalsignificance of products, the importance ofvalues beyond efficiency and the political biasinvolved with technological innovation.
