Reading achievement, metacognition, reading self-concept and interest: A study of German students in grades 3 and 4     

Christina E. van Kraayenoord  Wolfgang Erich Schneider 《European Journal of Psychology of Education - EJPE》1999,14(3):305-324

This study examined the reading achievement, metacognitive knowledge related to reading and memory, reading self-concept, and interest in reading of 140 German school students in Grades 3 and 4. The results indicated significant correlations between the metacognitive variables, motivational variables, and amongst metacognitive and motivational variables, as well as with reading achievement variables. The examination of good and poor readers showed significant differences in metacognitive knowledge of reading and memory, reading self-concept, interest in reading, and in teacher judgements of reading achievement between the groups. Differences between Grade 3 and 4 students were found in their word decoding skills, metacognitive knowledge about reading and memory, and teacher judgements of reading achievement. Results of the regression analysis indicated that reading achievement was predicted by grade level, word decoding, and teacher evaluations of reading achievement. The causal modelling indicated that motivation and metacognition affect reading comprehension in different ways. The findings are discussed in terms of future research and their educational implications.  相似文献   

Illuminating the Dark Ages: Pupil Dilation as a Measure of Expectancy Violation Across the Life Span     

Markus Krüger  Wolfgang Bartels  Horst Krist 《Child development》2020,91(6):2221-2236

Mainly for methodological reasons, little is known about the course of development of early cognitive competencies diagnosed with the violation of expectation (VoE) method in infants. The goal of this research was to evaluate the use of pupillometry as a unified approach to assess expectancy violations during and beyond the “dark ages” between 1 and 3 years. We tested children aged 1–6 years and adults (N = 279) with pictures of animals combined with matching or mismatching animal sounds. All age groups exhibited significantly greater pupil dilation in mismatched than matched trials. We conclude that pupillometry is a viable alternative to the VoE method that, by contrast to the latter, can be used throughout the life span.  相似文献   

Comparisons of observed process quality in early child care and education programs in five countries   总被引：2，自引：0，他引：2  

Wolfgang TietzeDebby CryerJoachim BairroJesús PalaciosGottfried Wetzel 《Early childhood research quarterly》1996,11(4):447-475

In this cross-national study, observed process quality in preschool classrooms was compared across five countries—Austria (n = 37), Germany (n=103), Portugal (n=88), Spain (n=80), and the U.S.A. (n=390). Process quality was assessed using the Early Childhood Environment Rating Scale (ECERS) and the Caregiver Interaction Scale (CIS). Both instruments had comparable properties when used in the different countries. A MANOVA found overall ECERS differences between countries, with Austria and Germany scoring higher than Spain, and Austria higher than the U.S.A. CIS Sensitivity scale differences showed Austria and Spain with higher scores than the U.S.A. Tests of homogeneity of variance showed U.S.A. with the highest standard deviations. A discriminant analysis, using countries as groups and ECERS items as criterion variables, revealed differences between countries on two discriminant functions: Personalized Care and Availability and Use of Space and Play Materials. Results are discussed in terms of the early childhood traditions and infrastructures found in the five countries.  相似文献   

Knowledge protection strategies of multinational firms—A cross-country comparison     

Pedro de Faria  Wolfgang Sofka 《Research Policy》2010,39(7):956-968

International knowledge spillovers, especially through multinational companies (MNCs), have recently been a major topic of discussion among academics and practitioners. Most research in this field focuses on knowledge sharing activities of MNC subsidiaries. Relatively little is known about their capabilities for protecting valuable knowledge from spilling over to host country competitors. We extend this stream of research by investigating both formal protection strategies (e.g. patenting) as well as strategic ones (secrecy, lead time, complex design). We conceptualize the breadth of firm's knowledge protection strategies and relate it to the particular situation of MNC subsidiaries. Moreover, we argue that their approaches differ with regard to host country challenges and opportunities. We address these issues empirically, based on a harmonized survey of innovation activities of more than 1800 firms located in Portugal and Germany. We find evidence that MNCs prefer broader sets of knowledge protection strategies in a host country with fewer opportunities for knowledge sourcing (Portugal). In Germany, though, they opt for narrower sets of knowledge protection strategies if they invest in innovation activities themselves. We deduce that these results are due to a need for reciprocity in knowledge exchanges to benefit fully from promising host country knowledge flows.  相似文献

Fatigue-related changes in technique emerge at different timescales during repetitive training     

Daniel Aragonés  Alexander Eekhoff  Fabian Horst  Wolfgang Immanuel Schöllhorn 《Journal of sports sciences》2018,36(11):1296-1304

Training consisting of numerous repetitions performed as closely as possible to ideal techniques is common in sports and every-day tasks. Little is known about fatigue-related technique changes that emerge at different timescales when repeating complex actions such as a karate front kick. Accordingly, 15 karatekas performed 600 kicks (1 pre-block and 9 blocks). The pre-block comprised 6 kicks (3 with each leg) at maximum intensity (K-100%). Each block comprised 60 kicks (10 with each leg) at 80% of their self-perceived maximum intensity (K-80%) plus 6 K-100%. In between blocks, the participants rested for 90 seconds. Right leg kinematics (peak joint angles, peak joint angular velocities, peak joint linear resultant velocities, and time of occurrence of peaks) and kick duration corresponding to the K-80% were measured resulting in numerous variations with fatigue. At the timescale of tens of seconds, the changes involved variables that were related to velocity of execution (slowed down), while variables related to movement form were hardly affected. At the timescale of tens of minutes, the opposite results were observed. These findings challenge the long-standing rationale underlying repetitive training, suggesting instead that such involuntary variations in technique might play a crucial role in motor skill training  相似文献   

Accuracy and precision of loadsol® insole force-sensors for the quantification of ground reaction force-based biomechanical running parameters     

Wolfgang Seiberl  Elisabeth Jensen  Josephine Merker  Marco Leitel  Ansgar Schwirtz 《European Journal of Sport Science》2018,18(8):1100-1109

Force plates represent the “gold standard” in measuring running kinetics to predict performance or to identify the sources of running-related injuries. As these measurements are generally limited to laboratory analyses, wireless high-quality sensors for measuring in the field are needed. This work analysed the accuracy and precision of a new wireless insole forcesensor for quantifying running-related kinetic parameters. Vertical ground reaction force (GRF) was simultaneously measured with pit-mounted force plates (1?kHz) and loadsol^® sensors (100?Hz) under unshod forefoot and rearfoot running-step conditions. GRF data collections were repeated four times, each separated by 30 min treadmill running, to test influence of extended use. A repeated-measures ANOVA was used to identify differences between measurement devices. Additionally, mean bias and Bland–Altman limits of agreement (LoA) were calculated. We found a significant difference (p?® devices for these parameters. For these same parameters, the LoA analysis showed that 95% of all measurement differences between insole and force plate measurements were less than 12%, demonstrating high precision of the sensors. However, highly dynamic behaviour of GRF, such as force rate, is not yet sufficiently resolved by the insole devices, which is likely explained by the low sampling rate.  相似文献
