The goal of this research was to highlight the role social regulatory processes play in making students’ teamwork in reciprocal teaching (RT) groups (a classroom activity in which students take the teacher’s role in small group reading sessions) effective. In addition to teamwork quality, we expected peer feedback to be a key factor in enhancing students’ reading comprehension achievements. Because previous research (Schünemann et al. in Contemp Educ Psychol 38:289–305, 2013) has shown that procedures of self-regulated learning (SRL) augment the effects of RT methods, we further assumed that such procedures would promote the quality of students’ collaborative efforts. In a cluster-randomized trial, students in 12 fifth-grade classes practiced a strategic approach to reading either in a RT condition or in a RT + SRL condition. In one of the 14 sessions, students’ interactive behavior was videotaped. Strategy use and reading comprehension were assessed at pretest, posttest, and maintenance. Performance differences between conditions were reliable only at maintenance. A multilevel mediation analysis showed that relative to RT students, RT + SRL students were better able to provide their teammates with informative feedback and organize their group work in a task-focused manner. Only feedback quality mediated the sustainability of treatment effects on strategy use and reading comprehension. In essence, this research suggests that effective reading comprehension trainings should integrate explicit instruction and practice in reading strategies, SRL, and focus on supportive peer processes in small groups with extensive instruction and practice in peer feedback.

Dieses open access-Buch analysiert den Zusammenhang von Berufsorientierung und politischer Bildung von Jugendlichen. Der Anspruch der Mündigkeitsbildung stellt die Ausgangsposition für die Vorstellungsforschung subjektiver Sinnbilder über die Berufs- und Arbeitswelt von Jugendlichen in der Sekundarstufe I dar. Dabei zeichnen sich Unterschiede in den Vorstellungen entlang der Trennlinien von sozioökonomischem Hintergrund, Herkunft, Geschlecht und Schulform ab. Die empirische Studie liefert wichtige Erkenntnisse zu den Vorstellungen und Handlungsmöglichkeiten von Schüler*innen und hilft zu verstehen, wovon diese abhängen und welche didaktischen Ansätze sich für die Berufsorientierung ableiten lassen.
Background: The aim of the present study was to investigate the psychometric characteristics of the Perceived Stress Scale (PSS) in a sample of dementia patients and their spousal caregivers. Methods: We investigated the reliability and validity of the 14-item PSS in a sample of 80 couples, each including one spouse who had been diagnosed with mild to moderate dementia (mean age 75.55, SD = 5.85, 38.7% female) and one spousal caregiver (mean age 73.06, SD = 6.75, 61.3% female). We also examined the factor structure and sensitivity of the scale with regard to gender differences. Results: Exploratory factor analysis of the PSS revealed a two-factor solution for the scale; the first factor reflected general stress while the second factor consisted of items reflecting the perceived ability to cope with stressors. A confirmatory factor analysis verified that the data were a better fit for the two-factor model than a one-factor model. The two factors of the PSS showed good reliability for patients as well as for caregivers ranging between alpha = 0.73 and alpha = 0.82. Perceived stress was significantly positively correlated with depressive symptomatology in both caregivers and patients. Mean PSS scores did not significantly differ between male and female patients nor did they differ between male and female caregivers. Conclusion: The present data indicate that the PSS provides a reliable and valid measure of perceived stress in dementia patients and their caregivers.
This article describes architectural extensions for a dynamically scheduled processor to enable three different operation modes, ranging from high-performance, to high-reliability. With minor extensions of the control path, the resources of the super-scalar data-path can be used either for high-performance execution, fail-safe-operation, or fault-tolerant-operation. Furthermore, the online error-correction capabilities are combined with reconfiguration techniques for permanent fault handling. This reconfiguration can take defective components out of operation permanently, and can be triggered on-demand during runtime, depending on the frequency of online corrected faults. A comprehensive fault simulation was carried out in order to evaluate hardware overhead, fault coverage and performance penalties of the proposed approach. Moreover, the impact of the permanent reconfiguration regarding the reliability and performance is investigated.
In this study, we investigated effects of morphological processing on handwriting production in beginning writers of German. Children from Grades 3 and 4 were asked to copy words from a computer screen onto a pen tablet, while we recorded their handwriting with high spatiotemporal resolution. Words involved a syllable-congruent visual disruption (e.g., "Golfer"), a morpheme-congruent visual disruption (e.g., "Golfer"), or had no disruption (e.g., "Golfer"). We analyzed productions in terms of Writing Onset Duration and Letter Duration at the onset of the second syllable ("f" in "Gol.fer") and the onset of the suffix ("e" in "Golf_er"). Results showed that durations were longer at word-writing onset only for words with a morpheme-congruent visual disruption. Also, letter durations were longer at the onset of the second syllable (i.e., "-fer") and shorter at the onset of the suffix (i.e., "-er") only for words with a syllable-congruent visual disruption. We interpret these findings within extant theories of handwriting production and offer an explanation for the observed effects before and during trajectory formation.
This study examined a theoretical model hypothesizing that reading strategies mediate the effects of intrinsic reading motivation, reading fluency, and vocabulary knowledge on reading comprehension. Using path analytic methods, we tested the direct and indirect effects specified in the hypothesized model in a sample of 1105 fifth-graders. In addition to standardized tests and questionnaires, we administered a performance test to assess students' proficiency in the application of three reading strategies. The overall fit of the model to the data was good. Both cognitive (fluency and vocabulary) and motivational (intrinsic reading motivation) variables had an indirect effect on reading comprehension through their influence on reading strategies. Reading strategies had a unique effect on reading comprehension and partially mediated the effects that cognitive and motivational variables had on fifth-graders' reading achievements.
The important role that metacognition plays as a predictor for student mathematical learning and for mathematical problem-solving, has been extensively documented. But only recently has attention turned to primary grades, and more research is needed at this level. The goals of this paper are threefold: (1) to present metacognitive framework during mathematics problem-solving, (2) to describe their multi-method interview approach developed to study student mathematical metacognition, and (3) to empirically evaluate the utility of their model and the adaptation of their approach in the context of grade 2 and grade 4 mathematics problem-solving. The results are discussed not only with regard to further development of the adapted multi-method interview approach, but also with regard to their theoretical and practical implications.
Does competent bilingualism entail advantages for the third language learning of immigrant students?
(2018)
This study examined the role of immigrant bilingualism in third language learning (L3 = English). It focused on the respective effects of students' competence in the minority language (L1 = Turkish or Russian) and language of instruction (L2 = German). We analyzed a sample of 8752 German 10th-grade students (N = 7964 monolinguals, N = 436 Turkish-German students, N = 352 Russian-German students) and drew on standardized tests in L1, L2, and L3. OLS-regression models showed L3 advantages for balanced bilinguals at a high level in both language groups compared to their average monolingual peers when third variables were controlled, while advantages in the L2 dominant bilinguals could only be observed in the Russian-German sample. Balanced bilinguals at a low level and L1 dominants attained lower L3 levels than monolinguals. However, comparisons with comparably high proficient monolinguals, as well as further analyses with the bilingual samples separately, revealed that only L2 competence – and not L1 competence – explained immigrant students' L3 proficiency. Our findings indicate that the advantages of immigrant bilinguals in L3 learning mainly depend on their competence in the language of instruction.
