One of the major shifts in education today under the influence of information and communication technologies is that there is an increased tendency toward the use of computer-mediated communications (CMC). CMC has developed an assortment of methods from simple e-mail to wireless instant messages and synchronous and asynchronous discussions. A large portion of the research in this area focuses on the pedagogical aspects of CMC particularly on the use, strategies, effectiveness and the integration of the new technologies for teaching and learning. Some studies investigate different perspectives of interaction like keeping track of asynchronous discussion, quality of participation, interaction and collaborative or group learning. This paper reports findings from the study that examines the quality of message ideas, thinking and interaction in an asynchronous CMC environment in a teacher training institution. The authors suggest some practical strategies in the implementation of asynchronous discussions in CMC environment. La qualité des messages d’idées, de la pensée et de l’interaction dans un environnement CMC asynchrone. Un des changements majeurs dans l’éducation aujourd’hui sous l’influence de l’information et des technologies de la communication est une tendance accrue À l’usage des communications par ordinateur (Computer-mediated Communications CMC). CMC a permis le développement de tout un assortiment de méthodes depuis de simples e-mail jusqu’À des messages sans fil instantanés et des discussions synchrones et asynchrones. Une grande partie de la recherche en ce domaine est centrée sur les aspects pédagogiques des CMC en particulier sur l’emploi, les stratégies, l’efficacité et l’intégration des nouvelles technologies pour l’enseignement et l’apprentissage. Certains études examinent les perspectives différentes de l’interaction. Telles que garder la trace des discussions asynchrones, la qualité de la participation interaction et l’apprentissage en coopération ou en groupe. L’article rapporte les résultats de l’étude qui examine la qualité des messages d’idées, la pensée et l’interaction dans un environnement de CMC asynchrone dans un établissement de formation des enseignants. Les auteurs suggérent des stratégies pratiques dans l’introduction de discussions asynchrones dans un environnement CMC. Die Qualität der übermittlung von Ideen, Denken und Interaktion in einem asynchronen CMC Umfeld Eine der wichtigsten Umstellungen der heutigen Ausbildung ist die unter dem Einfluss von Informations- und Kommunikationstechnologien verstärkte Tendenz, rechnergestützte Kommunikation (computer-mediated communications:CMC) zu benutzen. CMC hat ein ganzes Arsenal von Methoden entwickelt, von der einfachen E-Mail bis zu drahtlosen Nachrichten und synchron oder asynchron geführten Diskussionen. Die Forschung in diesem Bereich konzentriert sich hauptsächlich auf die pädagogischen Aspekte von CMC, besonders auf die Nutzung, die Strategien, den Wirkungsgrad und die Möglichkeiten der Einbindung der Neuen Technologien zum Lehren und Lernen. Einige Arbeiten erforschen die verschiedenen Perspektiven der Interaktion wie das Verfolgen von asynchronen Diskussionen, die Qualität der Beteiligung, der Interaktion und Zusammenarbeit oder dem Lernen in Gruppen. In diesem Beitrag wird über Ergebnisse der Studie zur Untersuchung der Qualität der übermittlung von Ideen, Gedanken und Interaktionen in einem asynchron arbeitenden rechnergestützten System (CMC) einer Lehrerfortbildungseinrichtung berichtet. Die Autoren erläutern praktische Strategien zur Einbindung asynchroner Diskussionen in eine CMC-Umgebung. 相似文献

Logical connectives are words or phrases which serve as links between sentences, or between propositions within a sentence,
or between a proposition and a concept. The Logical Connectives in Science Project has identified about 200 such terms commonly
use in school science text material, and has prepared over a thousand test items in order to measure secondary school students’
comprehension of these terms. The primary aim of the research is to identify students’ specific difficulties; a secondary
aim is to explore the relationships between students’ ability to comprehend logical connectives and other variables of interest
to educational researchers.
The research is still in progress; the present paper reports on recent work in four areas: (1) early findings on pupils’ difficulties
with logical connectives, based on data obtained from the trial testing of the items; (2) the relationship between logical
connective ability (LCA) and socio-economic status (SES); (3) the relationship between LCA and cognitive preferences; and
(4) the relationship between LCA and attitudes to a textbook (PSSC Physics) which makes extensive use of a wide range of logical
connectives. Significant correlations were found between LCA and SES; however, LCA was found to be uncorrelated with either
cognitive preferences or with attitudes to the PSSC text. 相似文献

The overarching aim of this study was to investigate students’ perceptions of the learning environment and whether these influenced their motivation and self-regulation in learning English as a second language at the university level in Jordan. Our sample involved 994 students, drawn from 13 schools, within three faculties (humanities, health sciences and engineering) of one university. The collection of data involved the administration of two surveys: one to assess students’ perceptions of the learning environment and another to assess students’ motivation and self-regulation in learning English as a second language. The results of analyses strongly supported the reliability and validity of the surveys when used at the university level in Jordan, thereby providing confidence in the results of the present study. Simple correlation and multiple regression analysis were used to examine the influence of students’ perceptions of the learning environment of English language classes on self-reports of motivation and self-regulation. Statistically significant (p < 0.05) simple correlations were found between students’ perceptions of their learning environment and their motivation and self-regulation. The regression weights (β) indicated that scales of the learning environment were positively, statistically significantly (p < 0.05) and independently related to the motivation and self-regulation outcomes. 相似文献

Relationships between students’ perceptions and their non-cognitive outcomes (epistemological beliefs, self-efficacy and attitudes to science) were investigated through secondary analysis of data from 14,167 United Arab Emirates students who participated in the Programme for International Student Assessment (PISA). Structural equation modeling (SEM) suggested that students’ perceptions of the learning environment were related to the non-cognitive outcomes of epistemological beliefs, self-efficacy and attitudes. Also, epistemological beliefs were found to have a statistically-significant and positive relationship with self-efficacy and attitudes, and self-efficacy was significantly related to attitudes.

We investigated students’ perceptions of their science classroom environments with the use of the What Is Happening In this Class? (WIHIC) questionnaire at the university level in Myanmar. The translated questionnaire was administered to 251 students in first-year science classes at a university. Both exploratory factor analysis and confirmatory factor analysis supported the reliability and factorial validity of the Myanmar version of the WIHIC. The constructs of the WIHIC were significantly correlated, but gender differences were not detected in correlations between WIHIC scales. Future research is needed to see if our Myanmar version of the WIHIC fits other samples in schools and universities in this context. It is also suggested that future studies include measures of student attitudes and academic achievement to permit investigation of associations between the learning environment and student outcomes in this country. 相似文献
