The observation of the present global scene raises questions about the socioeconomic, political and cultural framework laying the ground for a constructive interaction between the three forces which greatly determine people's existence and survival, namely Development, Democracy and Education. In this approach reference is made to John Dewey's classical remarks about the interrelation between Democracy and Education. They are examined in the light of specific historical conditions which are exemplified by references to the history of the Bohemian Lands and the first Czechoslovak Republic as well as by a critical view of current events, revealing the anti-human perversion of Dewey's model.
Zusammenfassung Ein Blick auf die gegenwärtige weltweite Szene wirft Fragen auf nach dem politischen und sozio-ökonomischen Rahmen, der Grundlage einer konstruktiven Interaktion der drei Kräfte ist, die vor allem die Existenz und das Überleben der Menschen bestimmen, nämlich Entwicklung, Demokratie und Bildung und Erziehung. Dieser Ansatz bezieht sich auf John Deweysklassische Bemerkungen über die Wechselwirkung von Demokratie und Bildung und Erziehung. Diese werden im Lichte spezifischer historischer Bedingungen untersucht, welche gleichermaßen am Beispiel der Geschichte der Böhmischen Länder und der ersten Tschechoslowakischen Republik veranschaulicht werden, wie durch einen kritischen Ausblick auf zeitgenössische Ereignisse, die die menschenfeindliche Perversion von Deweys Modell offenbaren.

Résumé L'observation de la scène actuelle soulève des questions au sujet du cadre socio-économique, politique et culturel qui constitue le fondement d'une interaction constructive entre les trois forces qui déterminent essentiellement l'existence et la survie des peuples, à savoir le développement, la démocratie et l'éducation. Cette approche se réfère aux remarques classiques de John Dewey sur l'interrelation entre la démocratie et l'éducation. On les examine en fonction de conditions historiques spécifiques illustrées par l'histoire des pays de la Bohème et de la première République tchécoslovaque ainsi que par une vue critique des événements actuels, qui révèlent la perversion misanthropique du modèle de Dewey.

High- and low-IQ children in the first, third, and fifth grades performed two free-recall tasks: a sort-recall task with sets of categorically related pictures, and a class-recall task, with children recalling the current members of their school class. All children were deemed to be experts concerning the composition of their school class, but, unlike experts in other domains, had no special motivation associated with their expertise. Recall and clustering on both tasks were high. The high-IQ children performed better than low-IQ children only on the sort-recall task. IQ was significantly correlated with measures of performance on the sort-recall task but not on the class-recall task. The results reflect the fact that the memory benefits associated with being an expert (here, elimination of IQ effects) are related to the greater knowledge the expert possesses and not to factors of motivation.  相似文献

Two reading literacy/text comprehension tests with different demands (on-line comprehension vs. memory-based comprehension) were administered to 6,104 15-year-old students from all German states and school types. The combined and specific effects of proximal and distal variables from small-scale psychological research as well as from large-scale educational studies on each text comprehension measure were investigated. Metacognitive knowledge, decoding speed, and the number of books at home (as an indicator for family background) were found to have specific and large effects on on-line comprehension and accounted for 46 percent of the variance with the highest effects for metacognition. Metacognitive knowledge was also highly predictive when the effects of specific prior knowledge and thematic interest on memory-based text comprehension were estimated simultaneously. In addition, students who showed relative strength in building up a coherent representation of specific texts (memory-based text comprehension) were characterised by high amounts of prior knowledge and thematic interest thereby underlining the importance of these student characteristics for learning.  相似文献

A possible explanation for why students do not benefit from learner-controlled instruction is that they are not able to accurately monitor their own performance. The purpose of this study was to investigate whether and how the accuracy of metacognitive judgments made during training moderates the effect of learner control on performance when solving genetics tasks. Eighty-six undergraduate students solved self-selected genetics tasks using either a full learner control or a restricted learner control. Results indicated that learner control effectiveness was moderated by the absolute accuracy (i.e., absolute bias) of metacognitive judgments, and this accuracy was a better predictor of learning performance for full learner control than for restricted learner control. Furthermore, students’ prior knowledge predicted absolute accuracy of both ease-of-learning judgments (EOLs) and retrospective confidence judgments (RCJs) during training, with higher prior knowledge resulting in a better absolute accuracy. Overall, monitoring guided control, that is, EOLs predicted time-on-task and invested mental effort regardless of the degree of learner control, whereas RCJs predicted the total training time, but not the number of tasks selected during training. These results suggest that monitoring accuracy plays an important role in effective regulation of learning from problem-solving tasks, and provide further evidence that metacognitive judgments affect study time allocation in problem solving context.  相似文献

Background and objective

Stroke volume variation (SVV) has high sensitivity and specificity in predicting fluid responsiveness. However, sinus rhythm (SR) and controlled mechanical ventilation (CV) are mandatory for their application. Several studies suggest a limited applicability of SVV in intensive care unit (ICU) patients. We hypothesized that the applicability of SVV might be different over time and within certain subgroups of ICU patients. Therefore, we analysed the prevalence of SR and CV in ICU patients during the first 24 h of PiCCO-monitoring (primary endpoint) and during the total ICU stay. We also investigated the applicability of SVV in the subgroups of patients with sepsis, cirrhosis, and acute pancreatitis.

Methods

The prevalence of SR and CV was documented immediately before 1241 thermodilution measurements in 88 patients.Results: In all measurements, SVV was applicable in about 24%. However, the applicability of SVV was time-dependent: the prevalence of both SR and CV was higher during the first 24 h compared to measurements thereafter (36.1% vs. 21.9%; P<0.001). Within different subgroups, the applicability during the first 24 h of monitoring ranged between 0% in acute pancreatitis, 25.5% in liver failure, and 48.9% in patients without pancreatitis, liver failure, pneumonia or sepsis.

Conclusions

The applicability of SVV in a predominantly medical ICU is only about 25%–35%. The prevalence of both mandatory criteria decreases over time during the ICU stay. Furthermore, the applicability is particularly low in patients with acute pancreatitis and liver failure.

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

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
