Abstract: [Im Beitrag wird] nach einer kurzen Darstellung der Gemeinsamkeiten statistischer Modellierung, die die Schul- und Bildungsforschung mit den meisten Sozialwissenschaften teilt, ein Überblick über die spezifischen Auswertungsverfahren gegeben, die sich vor allem in der quantitativen Bildungs- und Schulforschung häufig finden. Hierbei wird weniger auf die Darstellung spezifischer Kennwerte und ihrer Eigenschaften als auf die generelle Verwendung und den epistemologischen Zweck der Verfahren eingegangen. Der Fokus ist darauf gelegt, die wichtigsten statistischen Probleme und gegenwärtig gängigen analytischen Lösungen, wie sie in einer Vielzahl von Studien der Bildungs- und Schulforschung vorzufinden und zu adressieren sind, auf einer konzeptuellen Ebene zusammenzufassen und Hinweise für einen tieferen Einstieg in die Themen zu geben. Insofern sollen - nach einer kurzen Erläuterung der beiden grundlegenden Aspekte statistischer Modellierung (Deskriptive und Inferenzstatistik) im Allgemeinen - vier Aspekte quantitativer Auswertungen vorgestellt werden, wie sie unserer Meinung nach zentral für die quantitative Bildungs- und Schulforschung sind: (1) Hierarchische Datenstrukturen und Mehrebenenmodelle, (2) Pfadanalysen und längsschnittliche cross-lagged panel-Analysen, Fragen (3) fehlender Werte und (4) der Leistungsskalierung.

Abstract: Über den schulischen Umgang mit einer "Heterogenität" der Schüler*innen wird seit einer Reihe von Jahren heftig debattiert. Der vorliegende Band zeigt, wie seit dem letzten Drittel des 19. Jahrhunderts die Beobachtung von Unterschieden - solchen der Begabung, des Verhaltens und des Interesses - zwischen Schüler*innen in den Schulen mehr und mehr in das Blickfeld rückte. Auseinandersetzungen darüber, wie vor diesem Hintergrund "passende" Lerngruppen zusammengestellt werden sollten, bestimmten zunehmend das Bild der pädagogischen und schulpolitischen Debatten. Rekonstruiert werden Selektionsmechanismen im Schulsystem zwischen 1880 und 1980, mit denen zwischen Normalen und Nicht-Normalen, zwischen Begabten und Minderbegabten, zwischen solchen, die sich anpassten, und solchen, die das nicht taten, unterschieden wurde. Die Beiträge untersuchen Praktiken des Beobachtens, Prüfens und Beurteilens von Schüler*innen, die dafür eingesetzten Verfahren und Tests sowie die damit verbundenen individuellen, pädagogischen und politischen Bedingungen und Folgen.

Abstract: In high-stakes testing, often multiple test forms are used and a common time limit is enforced. Test fairness requires that ability estimates must not depend on the administration of a specific test form. Such a requirement may be violated if speededness differs between test forms. The impact of not taking speed sensitivity into account on the comparability of test forms regarding speededness and ability estimation was investigated. The lognormal measurement model for response times by van der Linden was compared with its extension by Klein Entink, van der Linden, and Fox, which includes a speed sensitivity parameter. An empirical data example was used to show that the extended model can fit the data better than the model without speed sensitivity parameters. A simulation was conducted, which showed that test forms with different average speed sensitivity yielded substantial different ability estimates for slow test takers, especially for test takers with high ability. Therefore, the use of the extended lognormal model for response times is recommended for the calibration of item pools in high-stakes testing situations. Limitations to the proposed approach and further research questions are discussed. (DIPF/Orig.)

Abstract (english): The increased availability of time-related information as a result of computer-based assessment has enabled new ways to measure test-taking engagement. One of these ways is to distinguish between solution and rapid guessing behavior. Prior research has recommended response-level filtering to deal with rapid guessing. Response-level filtering can lead to parameter bias if rapid guessing depends on the measured trait or (un-)observed covariates. Therefore, a model based on Mislevy and Wu (1996) was applied to investigate the assumption of ignorable missing data underlying response-level filtering. The model allowed us to investigate different approaches to treating response-level filtered responses in a single framework through model parameterization. The study found that lower-ability test-takers tend to rapidly guess more frequently and are more likely to be unable to solve an item they guessed on, indicating a violation of the assumption of ignorable missing data underlying response-level filtering. Further ability estimation seemed sensitive to different approaches to treating response-level filtered responses. Moreover, model-based approaches exhibited better model fit and higher convergent validity evidence compared to more naïve treatments of rapid guessing. The results illustrate the need to thoroughly investigate the assumptions underlying specific treatments of rapid guessing as well as the need for robust methods. (DIPF/Orig.)

Abstract (english): International large-scale assessments such as PISA or PIAAC have started to provide public or scientific use files for log data; that is, events, event-related attributes and timestamps of test-takers' interactions with the assessment system. Log data and the process indicators derived from it can be used for many purposes. However, the intended uses and interpretations of process indicators require validation, which here means a theoretical and/or empirical justification that inferences about (latent) attributes of the test-taker's work process are valid. This article reviews and synthesizes measurement concepts from various areas, including the standard assessment paradigm, the continuous assessment approach, the evidence-centered design (ECD) framework, and test validation. Based on this synthesis, we address the questions of how to ensure the valid interpretation of process indicators by means of an evidence-centered design of the task situation, and how to empirically challenge the intended interpretation of process indicators by developing and implementing correlational and/or experimental validation strategies. For this purpose, we explicate the process of reasoning from log data to low-level features and process indicators as the outcome of evidence identification. In this process, contextualizing information from log data is essential in order to reduce interpretative ambiguities regarding the derived process indicators. Finally, we show that empirical validation strategies can be adapted from classical approaches investigating the nomothetic span and construct representation. Two worked examples illustrate possible validation strategies for the design phase of measurements and their empirical evaluation. (DIPF/Orig.)

Controlling speed in component skills of reading improves the explanation of reading comprehension Goldhammer, Frank; Kroehne, Ulf; Hahnel, Carolin; De Boeck, Paul Journal Article | In: Journal of Educational Psychology | 2021 41462 Endnote: Author(s): Goldhammer, Frank; Kroehne, Ulf; Hahnel, Carolin; De Boeck, Paul

Abstract: Efficiency in reading component skills is crucial for reading comprehension, as efficient subprocesses do not extensively consume limited cognitive resources, making them available for comprehension processes. Cognitive efficiency is typically measured with speeded tests of relatively easy items. Observed responses and response times indicate the latent variables of ability and speed. Interpreting only ability or speed as efficiency may be misleading because there is a within-person dependency between both variables (speed-ability tradeoff [SAT]). Therefore, the present study measures efficiency as ability conditional on speed by controlling speed experimentally with item-level time limits. The proposed timed ability measures of reading component skills are expected to have a clearer interpretation in terms of efficiency and to be better predictors for reading comprehension. To support this claim, this study investigates two component skills, visual word recognition and sentence-level semantic integration (sentence reading), to understand how differences in ability in a timed condition are related to differences in ability and speed in a traditional untimed condition. Moreover, untimed and timed reading component skill measures were used to explain reading comprehension. A German subsample from Programme for International Student Assessment (PISA) 2012 completed the reading component skills tasks with and without item-level time limits and PISA reading tasks. The results showed that timed ability is only moderately related to untimed ability. Furthermore, timed ability measures proved to be stronger predictors of sentence-level and text-level reading comprehension than the corresponding untimed ability and speed measures, although using untimed ability and speed jointly as predictors increased the amount of explained variance.

Abstract (english): This study aimed at examining the suitability of questionnaire instruments commonly used in large-scale assessments for measuring non-cognitive school effectiveness criteria. It focused on questions of reliability and validity for capturing changes in students within schools across time and the instruments' sensitivity to school effects. The aim was also to propose an approach for analyzing measurement invariance across levels and time simultaneously. The study used longitudinal data from the KESS (Kompetenzen und Einstellungen von Schülerinnen und Schülern [competencies and attitudes of students]) study, conducted in Hamburg, Germany. The sample is comprised of 17,926 students in 189 secondary schools. Data were collected three or four times. The results of the analyses show that all investigated scales are suitable in terms of reliability and validity. However, only the scale interest in mathematics is sensitive to school effects and therefore suitable as a school effectiveness criterion. (DIPF/Orig.)

Abstract: The study investigates automated and controlled cognitive processes that occur when university students read multiple documents (MDs). We examined data of 401 students dealing with two MD sets in a digital environment. Performance was assessed through several comprehension questions. Recorded log data gave indications about students' time allocation, corroboration, and sourcing. Independent measures were used for reading speed to tap the effects of automatic processing and for working memory and single-text reading comprehension to tap effects of controlled processing, with working memory considered the mental capacity for performing controlled processing. We found that faster readers completed the MD tasks faster and showed more corroboration behavior. At the same time, students skilled in comprehension allocated more time to processing MD tasks and were more likely to show MD-specific behaviors of corroboration and sourcing. Students' success in MD tasks was predicted by reading speed and working memory, with the effect of working memory being mediated by single-text comprehension. Behavioral indicators contributed independently in predicting students' MD comprehension. Results suggest that reading MDs resembles a problem-solving situation where students need to engage in controlled, non-routine processing to build up a comprehensive representation of MDs and benefit from highly automated, lower-level reading processes.

Abstract: The article focuses on estimating effects in nonrandomized studies with two outcome measurement occasions and one predictor variable. Given such a design, the analysis approach can be to include the measurement at the previous time point as a predictor in the regression model (ANCOVA), or to predict the change-score of the outcome variable (CHANGE). Researchers demonstrated that both approaches can result in different conclusions regarding the reported effect. Current recommendations on when to apply which approach are, in part, contradictory. In addition, they lack direct reference to the educational and instructional research contexts, since they do not consider latent variable models in which variables are measured without measurement error. This contribution assists researchers in making decisions regarding their analysis model. Using an underlying hypothetical data-generating model, we identify for which kind of data-generating scenario (i.e., under which assumptions) the defined true effect equals the estimated regression coefficients of the ANCOVA and the CHANGE approach. We give empirical examples from instructional research and discuss which approach is more appropriate, respectively. (DIPF/Orig.)

Abstract (english): The reading acceleration phenomenon refers to the effect that experimentally induced time constraints can generate instantaneous improvements of reading rate, accuracy and comprehension among typical and reading impaired readers of different age groups. An overview of studies applying the fading manipulation (i.e., letters are erased in reading direction), which induces the time constraints causing the acceleration phenomenon, is provided in the first part of this review. The second part summarises the outcomes of studies using a training approach called the reading acceleration program (RAP) that integrated core principles of the acceleration phenomenon to generate persistent reading performance improvements. Our review shows ample evidence for the validity of the acceleration phenomenon, since it has been replicated across various languages and populations. However, although there are several explanatory approaches for underlying mechanisms, none of them is well substantiated by empirical evidence so far. Similarly, although generally positive effects of RAP training were reported for several languages and groups of readers, the exact mechanisms causing improved reading rates and comprehension are not well understood. Our critical discussion points out several limitations of RAP that call for further research. However, we also highlight several benefits regarding RAP's potential as an intervention approach for enhancements in reading performance. (DIPF/Orig.)
