Instructional Science - Digital drawing can foster learning, but only if the drawing is of sufficient quality. Hence, the focus of the present study was to investigate whether and how two types of...  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

Student participation styles in adventure education     

Mark H. Zmudy  Matthew D. Curtner-Smith  Jeff Steffen 《Sport, Education and Society》2013,18(4):465-480

Sport pedagogy researchers have contributed much to the literature on physical education teaching by describing the participation styles of children, youth and young adults in various settings. The purpose of this study was to describe the participation styles of children enrolled in two consecutive week-long summer adventure camps. Primary participants were 31 elementary and middle school students. Secondary participants were the two adventure educators (AEs) responsible for carrying out all the instruction at the camps. Data were collected using a variety of qualitative techniques and analysed using standard interpretive methods. Nine participation styles were identified indicating that the children in the camps had differing experiences of adventure education and varying degrees of success. Some of the participation styles had similar characteristics to those discovered previously in middle school physical education. Despite these similarities and unlike the middle school setting, there was no indication that a hierarchy of participation styles existed and, consequently, there was no sign of any bullying. Reasons for this difference may well have been the heavy focus on affective objectives within adventure education, much lower student–teacher ratios, higher levels of supervision and management, and greater instructional intent and skill.  相似文献   

The Practicum in Study of Student Development: Its Relation to Counselor Preparation     

C. E. Kennedy  D. G. Danskin  S. K. Edelman  J. D. Steffen 《Counselor Education & Supervision》1970,9(4):272-276

This paper identifies several kinds of counselor activity for which practicum experiences have been or are being designed. These include individual and group counseling, outreach consultation, supervision of practicum students, and the study of student development. The SSD practicum is seen as sensitizing and predisposing the personnel worker to view action research as a relevant and crucial part of counselor education.  相似文献   

The Cavendish Experiment as a Tool for Historical Understanding of Science     

Steffen Ducheyne 《Science & Education》2012,21(1):87-108

Following an ever growing literature which takes serious the relevance of case-studies in the history of science for science education and understanding of science, I provide a detailed historical reconstruction of the Cavendish Experiment, which remains as close as possible to the original. In this paper, I call attention to three educational benefits of familiarizing students with the Cavendish Experiment and its aftermath.  相似文献   

Entwurf und Implementierung eines SQL-normkonformen Datenbankkatalogs für ein relationales Datenbankmanagementsystem     

Steffen Skatulla  Ralf Schaarschmidt  Peter Pistor  Klaus Küspert 《Informatik - Forschung und Entwicklung》2000,22(2):161-170

Bei relationalen Datenbanksystemen haben sich de-jure-Normen für SQL stetig weiterentwickelt; mit diesen Normen wird es einfacher, portable Datenbankanwendungen zu entwickeln. Die SQL-Norm ruht auf zwei S?ulen, zum einen auf der Datenbanksprache SQL, zum anderen auf einer Vorgabe eines Datenbankkatalogs, welcher die gespeicherten Daten beschreiben soll. Im vorliegenden Beitrag wird derjenige Teilbereich des Datenbankkatalogs der aktuellen SQL99-Norm dargestellt, der bereits in der SQL92-Norm (ISO/IEC 9075:1992 bzw. DIN 66315) definiert ist und die klassischen (nicht objektrelationalen) Elemente einer relationalen Datenbank beschreibt. In dieser Darstellung nimmt der zweischichtige Spezifikationsansatz (Informationsschema, Definitionsschema) einigen Raum ein; mit seiner Hilfe weist SQL einen eleganten Weg, auf dem existierende Datenbanksysteme normkonforme Datenbankkataloge bereitstellen k?nnen. Anhand des Datenbankmanagementsystems DB2 wird anschlie?end untersucht, wie ein normkonformer Datenbankkatalog (das sogenannte Informationsschema) „oberhalb” des verfügbaren DB2-Katalogs realisiert werden kann, d. h. wie die vom Informationsschema geforderten Sichten auf DB2-Katalogtabellen abgebildet werden k?nnen. Auf generelle Schwierigkeiten und M?glichkeiten einer solchen Abbildung (ein- oder zweistufig) wird ebenso eingegangen wie auf Probleme, die sich speziell bei DB2 ergeben. In einer prototypischen Realisierung konnte das Informationsschema bis auf wenige Einschr?nkungen komplett umgesetzt werden. Damit wurde die Machbarkeit normkonformer Kataloge nachgewiesen. In heute verfügbaren DBMS-Produkten sind Datenbankkataloge in dieser konsequent normkonformen Gestalt leider immer noch nicht anzutreffen.  相似文献   

Building a technology foundation for future teachers     

Dr. Leslie J. Davison  David Burr  Jean C. Eberlein  Daniel J. Fuchs  Lupita Saucedo  Bob H. Steffen 《TechTrends》2000,44(4):11-15

It is fitting that the teachers of tomorrow are provided with the correct modeling of technology in their first education class. To separate technology from education is both impossible and foolish. The sooner college students are exposed to the latest forms of technology, the more equipped they will be to integrate these tools into their teaching strategies for the benefit of future learners.  相似文献

Should Regularization Replace Simple Structure Rotation in Exploratory Factor Analysis?     

Florian Scharf  Steffen Nestler 《Structural equation modeling》2019,26(4):576-590

Exploratory factor analysis (EFA) is an important tool when the measurement structure of psychological constructs is uncertain. Typically, factor rotation is applied to obtain interpretable results resembling a simple structure. However, an overwhelming multitude of rotation techniques is available of which none is unequivocally superior. Recently, regularization has been suggested as an alternative to factor rotation. In two simulation studies, we addressed the question if regularized EFA is a suitable alternative for rotated EFA. We compared their performance in recovering predefined factor loading patterns with varying amounts of cross-loadings. Elastic net regularized EFA yielded estimates comparable to rotated EFA. For complex loading patterns, both rotated and regularized EFA tended to underestimate cross-loadings and inflate factor correlations, but regularized EFA was able to recover loading patterns as long as a subset of items followed a simple structure. We conclude that regularization is a suitable alternative to factor rotation for psychometric applications.  相似文献
