The influence of contrast and assimilation effects on self-evaluation of performance as well as task interest has been widely researched in observational studies under the labels big-fish-little-pond and basking-in-reflected-glory effect. This study examined the influence of similar contrast and assimilation effects in an experimental paradigm. Fifth and sixth grade students (n = 230) completed a computer-based learning task during which they received social comparative feedback based on 2 × 2 experimentally manipulated feedback conditions: social position (high vs. low) and peer performance (high vs. low). Results show a more positive development of task interest and self-evaluation of performance in both the high social position and the high peer performance condition. When applied to the school setting, results of this study suggest that students who already perform well in comparison to their peer group are also the ones who profit most from social comparative feedback, given that they are the ones who usually receive the corresponding positive performance feedback.

Building on this, the present study examines the questions of how the number of friendships and their quality differ between students with and without SEN and whether a homophily-effect can be identified. The sample consists of 455 fourth-graders from 28 inclusive classes in Austria. The results indicate that students with SEN have fewer friends than students without SEN. Furthermore, students without SEN preferred peers without SEN as a friend. This homophily-effect was shown for students with SEN, too. However, students with and without SEN rated the quality of their friendships similarly and no interactions between the SEN status of oneself or of the friend was found for the quality of the friendship. The results show that, in the context of inclusion, the issue of friendship needs to be increasingly addressed to improve the situation of students with SEN.

Because objective measures of interaction partners' language skills are rarely available, third party ratings may be an alternative measure. Therefore, the present study investigates students' ratings of their fellow students' language skills as indicators of actual language performance in German and the heritage languages Turkish and Russian. Multilevel models were applied to address the following questions: Which factors influence students' ratings of peers' language skills? How accurate are these ratings and what influences the accuracy of ratings? In all languages, students' ratings were moderately related to peers' test performance and the accuracy of ratings was positively moderated if the students had class together, shared the same language background and with increasing relationship quality. The ratings for German language abilities further revealed negative performance related stereotypes towards peers with Turkish and Russian language backgrounds. The results are discussed with respect to possibilities and boundaries of assessing peers' language skills through student ratings and implications of negative performance related stereotypes. N2 - Modellen der Sprachaneignung zufolge sind für die die Entwicklung sprachlicher Fähigkeiten auch die sprachlichen Fähigkeiten von wichtigen Interaktionspartnern (z. B. Peers) bedeutsam. Da objektive Kompetenzmaße von Interaktionspartnern selten verfügbar sind, könnten alternativ Fremdeinschätzungen der sprachlichen Fähigkeiten erhoben werden. Im Beitrag wurden daher Schülerurteile über sprachliche Fähigkeiten von Mitschüler(inne)n im Deutschen und den Herkunftssprachen Türkisch und Russisch als potentielle Indikatoren tatsächlicher Sprachfähigkeiten untersucht. Mit Hilfe von Mehrebenenmodellen wurde analysiert, welchen Einflussfaktoren die Fremdeinschätzungen unterlagen, wie akkurat diese ausfielen und unter welchen Bedingungen akkuratere Einschätzungen gelangen. In allen Sprachen ergaben sich moderate Zusammenhänge zwischen den Fremdeinschätzungen und objektiven Leistungsmaßen, wobei die Urteilsakkuratheit insbesondere von Merkmalen auf der Beziehungsebene zur eigeschätzten Person (gemeinsamer Unterricht, geteilter Sprachhintergrund, Beziehungsqualität) moderiert wurde. Im Deutschen zeigten sich negative leistungsbezogene Vorurteile gegenüber Jugendlichen mit türkischer und russischer Herkunftssprache. Die Ergebnisse werden in Bezug auf Möglichkeiten und Grenzen von Fremdeinschätzungen sprachlicher Fähigkeiten sowie auf Konsequenzen leistungsbezogener Vorurteile diskutiert.

They are commonly applied to examine the effectiveness of classroom-based interventions to reduce problem behavior in schools. At the same time, there is no consensus on good design characteristics of single-case experimental designs when dealing with behavioral problems in schools. Moreover, specific challenges arise concerning appropriate approaches to analyzing behavioral data. Our study addresses the interplay between the test power of piecewise regression analysis and important design specifications of single-case research designs. Here, we focus on the influence of the following specifications of single-case research designs: number of measurement times, the initial frequency of the behavior, intervention effect, and data trend. We conducted a Monte-Carlo study. First, simulated datasets were created with specific design conditions based on reviews of published single-case intervention studies. Following, data were analyzed using piecewise Poisson-regression models, and the influence of specific design specifications on the test power was investigated. Our results indicate that piecewise regressions have a high potential of adequately identifying the effects of interventions for single-case studies. At the same time, test power is strongly related to the specific design specifications of the single-case study: Few measurement times, especially in phase A, and low initial frequencies of the behavior make it impossible to detect even large intervention effects. Research designs with a high number of measurement times show robust power. The insights gained are highly relevant for researchers in the field, as decisions during the early stage of conceptualizing and planning single-case experimental design studies may impact the chance to identify an existing intervention effect during the research process correctly.

JF - frontiers in Education N2 - Internalizing problems in children belong to the category of special educational needs called emotional and behavioral difficulties. Recent decades have witnessed a critical discussion about whether children and adolescents experiencing internalizing problems are at risk of being sociometrically neglected (neither liked nor disliked by their peers). Previous studies have shown evidence both for and against the association between internalizing problems and neglected sociometric status. These contradictory results may be due to the following methodological aspects: (1) shortcomings of sociometric status classification methods (arbitrariness of the sociometric classification rules) and (2) different operationalizations of internalizing problems (broadband and narrowband dimensions of behavior). The aim of the present study is to investigate empirically whether and to what extent these methodological aspects lead to contradictory results on the internalizing behavior of neglected students. This question is investigated using a sample of students (N = 2334) in German inclusive primary schools. The systematic investigation presented here provides initial indications that the various methodological approaches can lead to conflicting results. The contradictory results are not only due to the application of different sociometric classification methods, but also to different operationalizations of internalizing behavior (narrowband and broadband scales). Earlier contradictory evidence on the internalizing behavior of neglected students must therefore be seen in a different light: the reasons for previously conflicting results may actually be methodological. Based on the results, conclusions are drawn as to how methodological aspects can be given more consideration in sociometric research on internalizing behavior.
