The University of North Florida, in partnership with educational, business, and community agencies, has established the Florida Early Literacy and Learning Model (ELLM) to improve literacy among over 1,000 4-, 5-, and 6-year-olds in the region. The ELLM initiative is founded on the concepts of collaborative restructuring, reading research, high-performance learning environments, and family involvement. It has been found to be effective in increasing literacy and reading achievement of young children who have come to school underprepared. 相似文献

This review focuses on the structuring of research models to investigate communication in intimate relationships. Two major issues addressed are: (1) the nature of outcome variables isolated for study; and (2) the need to integrate multiple theoretical perspectives to understand communication context. Suggestions are offered for defining and measuring dyadic level, instrumental, time‐bound, and evaluative communication effects. A dialectic view of communication context is presented which integrates varied perspectives for organizing and analyzing the antecedents and consequences of intimates’ communication. 相似文献

ABSTRACT Cross-country skiing is a complex endurance sport requiring technical skills, in addition to considerable physiological and tactical abilities. This review aims to identify biomechanical factors that influence the performance of cross-country skiers. Four electronic databases were searched systematically for original articles in peer-reviewed journals addressing the relationship between biomechanical factors (including kinematics, kinetics, and muscle activation) and performance while skiing on snow or roller skiing. Of the 46 articles included, 22 focused exclusively on the classical technique, 18 on the skating technique, and six on both. The indicators of performance were: results from actual or simulated races (9 articles); speed on specific tracts (6 articles); maximal or peak speed (11 articles); skiing economy or efficiency (11 articles); and grouping on the basis of performance or level of skill (12 articles). The main findings were that i) cycle length, most often considered as a major determinant of skiing speed, is also related to skiing economy and level of performance; ii) higher cycle rate related with maximal speed capacity, while self-selected cycle rate improves skiing economy at sub-maximal speeds; iii) cross-country skiing performance appears to be improved by joint, whole-body, ski, and pole kinematics that promote forward propulsion while minimizing unnecessary movement. 相似文献

Software-Entwurfsmuster sind eine intuitiv einleuchtende Idee, die viele Befürworter hat. Als Forscher dürfen wir die behaupteten Wirkungen von Entwurfsmustern jedoch nicht einfach glauben, sondern müssen sie gründlich prüfen. Dieser Artikel beschreibt die wichtigsten Behauptungen und entwickelt daraus zugeh?rige Forschungsfragen. Wir diskutieren die Methodik für ein Forschungsprogramm, das die Fragen beantworten soll, und skizzieren praktische Beschr?nkungen, unter denen diese Forschung ablaufen mu?. Es folgt eine kurze Beschreibung von drei kontrollierten Experimenten und den Hauptfolgerungen aus ihren Ergebnissen. So sollte man zum Beispiel die Benutzung von Entwurfsmustern in einem Entwurf genau dokumentieren und Entwurfsmuster nicht einsetzen, ohne alternative Entwürfe zu prüfen. Abschlie?end diskutieren wir ein im Rahmen des Forschungsprogramms geplantes viertes Experiment. Der Beitrag dieses Artikels liegt vorrangig in einer Beschreibung und Diskussion wichtiger methodischer Aspekte kontrollierter Experimente in der Softwaretechnik. 相似文献

Changes in global patterns of residence mean that preschool teachers welcome immigrant children and families into preschools
in increasing numbers. Many teachers report both anticipation and apprehension about having immigrant children in the classroom.
Apprehension is related to concerns about a lack of enough knowledge about languages and cultures to sensitively work with
children and families. To overcome apprehensions and challenges, teachers are encouraged to learn from the work of other adults.
This study builds upon research that suggests that teachers can also look to the children as a source of knowledge. The purpose
of this study was to explore how preschool immigrant children might use a disposable camera to communicate with their teachers.
The participants of this qualitative study were immigrant and native-born students in a local preschool. Each child was given
a disposable camera, instruction about taking photographs and the request to take pictures of what was important to them.
Data were collected by recording each child telling the teacher about the pictures. Data were analyzed for themes, patterns
and categories. Findings indicated that the messages that the children conveyed to their teachers included important information
about language development and family cultural identity. Findings also identify teacher strategies that helped and hindered
child ability to communicate during the photo-narration process. An implication of the study was a shift of child agency within
the teacher child relationship during photo-narration activity. 相似文献
