AutoFocus – Ein Werkzeugprototyp zur Entwicklung eingebetteter Systeme     

Manfred Broy  Franz Huber  Bernhard Sch?tz 《Informatik - Forschung und Entwicklung》1999,12(4):121-134

Der Beitrag stellt AutoFocus vor, einen Werkzeugprototyp zur Entwicklung verteilter, eingebetteter Systeme auf der Grundlage formaler Techniken. AutoFocus unterstützt die Systementwicklung mit integrierten, im wesentlichen graphischen Beschreibungstechniken, mit deren Hilfe sowohl unterschiedliche Sichten als auch verschiedene Abstraktionsebenen eines Systems beschrieben werden. Um konsistente und vollst?ndige Beschreibungen sicherzustellen, bietet AutoFocus die M?glichkeit, Konsistenzbedingungen zu formulieren und Systembeschreibungen daraufhin zu überprüfen. Aus ausführbaren Spezifikationen k?nnen Prototypen des entwickelten Systems erzeugt werden und in einer Simulationsumgebung ausgeführt und visualisiert werden. Zur formalen Verifikation von Systemeigenschaften verfügt AutoFocusüber Anbindungen an Modellprüfungswerkzeuge wie -cke oder SMV.  相似文献

海德格尔—马克思主义：元儒家的要素     

弗朗茨·费尔瑟 《淮阴师范学院学报(哲学社会科学版)》2010,32(5):597-600

近代以来的历史是一部人的异化史,近代以来的技术进步是存在遗忘自身的过程。海德格尔和马克思认为,这是一个不可避免的过程,是人类进步必须付出的代价。但是,从东方的儒家、道家和佛教所组成的＂元儒家＂的思想出发,我们可以证明,资本主义和帝国主义及其带来的灾难并不拥有必然性的光环。从另一个角度看,从教条主义中解放出来的马克思主义和海德格尔的关于存在之思可以与＂元儒家＂共同承担起对当代社会的批判以及对未来社会的建构的使命,并因此而成为＂元儒家＂的核心要素。  相似文献

Concept Mapping Assessment of Media Assisted Learning in Interdisciplinary Science Education     

Steffen Schaal  Franz X. Bogner  Raimund Girwidz 《Research in Science Education》2010,40(3):339-352

Acquisition of conceptual knowledge is a central aim in science education. In this study we monitored an interdisciplinary hypermedia assisted learning unit on hibernation and thermodynamics based on cooperative learning. We used concept mapping for the assessment, applying a pre-test/post-test design. In our study, 106 9th graders cooperated by working in pairs (n = 53) for six lessons. As an interdisciplinary learning activity in such complex knowledge domains has to combine many different aspects, we focused on long-term knowledge. Learners working cooperatively in dyads constructed computer-supported concept maps which were analysed by specific software. The data analysis encompassed structural aspects of the knowledge corresponding to a target reference map. After the learning unit, the results showed the acquisition of higher-order domain-specific knowledge structures which indicates successful interdisciplinary learning through the hypermedia learning environment. The benefit of using a computer-assisted concept mapping assessment for research in science education, and in science classrooms is considered.  相似文献   

Implementation of concept mapping to novices: reasons for errors,a matter of technique or content?     

Cathérine Conradty  Franz X. Bogner 《Educational studies》2010,36(1):47-58

Concept mapping is discussed as a means to promote meaningful learning and in particular progress in reading comprehension skills. Its increasing implementation necessitates the acquisition of adequate knowledge about frequent errors in order to make available an effective introduction to the new learning method. To analyse causes of errors, 283 A‐level sixth graders produced concept maps about two differently complex subject matter lessons, we implemented in a pre‐lesson. We defined six types of errors and analysed the distribution and contingency tables in both subject matters. Students in general produced more complex concept maps in the context of the easier subject matter (A) than that of the difficult content (B). Whereas in the former errors simply indicated knowledge gaps, in the latter they often reflected technical misconceptions. The occurrence of a content‐dependent technical error in (B) pointed to a cognitive overload, since the more difficult content is hypothesised to cause higher intrinsic load. From this following, concept mapping could provoke an instructional enrichment by additionally revealing specific knowledge gaps.  相似文献   

Student attitudes that predict participation in peer assessment     

Yan Zou  Christian Dieter Schunn  Fuhui Zhang 《Assessment & Evaluation in Higher Education》2018,43(5):800-811

Peer assessment has been widely applied to actively engage students in learning to write. However, sometimes students resist peer assessment. This study explores reviewers’ attitudes and other underlying factors that influence students’ participation in online peer assessment. Participants were 234 Chinese undergraduates from two different academic backgrounds: engineering majors (n = 168) and English majors (n = 66). Gender, academic background and prior experience with peer assessment were all related to participation levels. Moreover, factor analyses revealed three attitudinal factors: (1) positive attitude (a general endorsement of the benefits of peer assessment), (2) interpersonal negative (concerns about the negative effects on interpersonal relationships), and (3) procedural negative (doubts about the procedural rationality of peer assessment). Among the attitudinal factors, procedural negative was negatively associated with participation, as expected. Interestingly, interpersonal negative was associated with greater participation, and positive attitude was associated with lower participation, in part because students worked hard on each review rather than doing many reviews superficially. Implications for instruction are discussed.  相似文献   

Pädagogische Begleitung: Handlungsform und Systemmerkmal     

Dieter Nittel  Nikolaus Meyer 《Zeitschrift für Erziehungswissenschaft》2018,21(5):1063-1082

This contribution aims to lay down the theoretical potential of accompaniment as a phenomenon and developing this point further from a pedagogical perspective. The core assumption is that accompaniment represents both a pedagogically relevant phenomenon of action as well as an essential characteristic of the system. In this sense, accompaniment can be understood as creating a possibility for looking at phenomena of education on a micro and a macro level. Thus, the assumption follows that a central signature of the social system – namely that of inclusion – has already been incorporated by the pedagogically organized system of lifelong learning a long time ago. This finding has far-reaching consequences for levelling the hierarchy between different layers of the education and learning systems.  相似文献   

Reliability and validity of the Yo-Yo intermittent recovery test level 1 in young soccer players

Abstract

The present study investigated the test-retest reliability from the Yo-Yo IR1 (distance and heart rate responses), and the ability of the Yo-Yo IR1 to differentiate between elite and non-elite youth soccer players. A total of 228 youth soccer players (11–17 years) participated: 78 non-elite players to examine the test-retest reliability within 1 week, added with 150 elite players to investigate the construct validity. The main finding was that the distance covered was adequately reproducible in the youngest age groups (U13 and U15) and highly reproducible in the oldest age group (U17). Also, the physiological responses were highly reproducible in all age groups. Moreover, the Yo-Yo IR1 test had a high-discriminative ability to distinguish between elite and non-elite young soccer players. Furthermore, age-related standards for the Yo-Yo IR1 established for elite and non-elite groups in this study may be used for comparison of other young soccer players.  相似文献   

Metacognition and Middle Grade Mathematics Teachers: Supporting Productive Struggle     

Stephanie M. Lemley  Jessica T. Ivy  Dana Pomykal Franz  Seth F. Oppenheimer 《Clearing house (Menasha, Wis.)》2019,92(1-2):15-22

Communicating mathematical ideas through writing, listening, and verbalizing allows students to think about how they “think” about mathematics. By focusing this communication on a reflection of how one thinks about mathematics, metacognitive writing engages students as mathematicians and learners. In this article we describe a professional development that we implemented with middle grade mathematics teachers focused on metacognitive writing as a tool to support productive struggle in the mathematics classroom. Thus, this practitioner article adds to the knowledge base on how to develop middle grade teachers metacognitive writing through engagement in productive struggle. Recommendations for practice are included.  相似文献
