A large number of studies in CMC have assessed how social interaction, processes and learning outcomes are intertwined. The present research explores how the degree of self-determination of learners, that is the motivational orientation of a learner, influences the communication and interaction patterns in an online Problem Based Learning environment. Given the complexity of CMC, we expected that autonomous learners would be more willing to contribute to cognitive discourse. In time, we expected that control-oriented learners would develop a preferential attachment to contribute to discourse from autonomous learners. Data were gathered from 37 autonomous and 39 control-oriented learners who posted 1669 messages. Using a dynamic multi-method approach of content analysis of cognitive and social discourse, social network analysis, and measures of academic motivation, we find some preliminary evidence that motivational orientation influences communication and social interaction patterns amongst learners. From the beginning, most control-oriented learners develop a preference to connect to and communicate with autonomous learners, although a separate team-analysis indicates that group dynamics also influence how learners develop connections with other learners in time. Our findings further the understanding of differences found in distance learning courses about participation and drop-out. 相似文献

ABSTRACTUsing classical and quantile regression analyses, we investigated whether predictor variables for early reading comprehension differed depending on language background and ability level in a mixed group of 161 monolingual (L1) and bilingual (L2) children in second grade (6–8 years). Although L2 readers scored lower on oral language skills and reading comprehension, the prediction of reading comprehension was similar for L1 and L2 readers. Classical regression identified decoding, vocabulary, and morphosyntactic knowledge as unique predictors with no interaction with language background. Quantile regression demonstrated that the prediction of reading comprehension differed across ability levels; decoding and morphosyntactic knowledge were consistently unique predictors, but vocabulary was uniquely related only for poor comprehenders and working memory only for good comprehenders. In both types of analysis, language background did not explain unique variance, indicating that individual differences in the predictor variables explained the L1–L2 performance gap in early reading comprehension across the ability range. 相似文献

Inquiry-based lessons have been demonstrated to improve children’s scientific thinking (i.e. reasoning abilities and domain-specific knowledge). Although empirical evidence shows that inquiry-based learning requires instruction, research comes from two approaches that have not been bridged yet: direct instruction of scientific reasoning and teacher training of verbal support. We investigated how these two types of instruction separately or combined strengthened children’s scientific thinking by comparing four conditions: baseline, direct instruction, verbal support, and a combined approach. Effectiveness of an inquiry-based lesson series on scientific reasoning abilities, vocabulary, and domain-specific knowledge (near and far transfer) were studied among 301 fourth graders. Results showed that both approaches strengthened different components of scientific reasoning abilities, and that a combination of instructions was most effective for scientific reasoning abilities, vocabulary, and domain-specific knowledge. Domain-specific knowledge acquisition was strengthened only when both instructions were provided. It can thus be concluded that each type of instruction has unique contributions to children’s science learning and that these instructions complement each other. Our study thus showed that inquiry-based lesson series when preceded by direct instruction of scientific reasoning and scaffolded with verbal support are most effective. 相似文献

The current study used a dyadic and coconstructive approach to examine how to embed exercises that support executive functioning into early literacy instruction to empower its effects. Using a randomized controlled trial design with 100 children, we examined the effects of dyadic activities in which children scaffolded each other’s learning and behavior through structured questioning procedures. This group was contrasted with a control group whose dyads observed each other while working with the same literacy exercises and with a business-as-usual control group. Research Findings: Results showed that the experimental group showed greater progress in letter knowledge. Further analyses indicated that these results were mainly driven by children with higher levels of executive functions. Practice or Policy: These results suggest that young children are able to regulate each other’s learning behavior during preacademic exercises in dyadic contexts but may need more external control from a teacher when their executive function levels are low. 相似文献

With the increasing popularity of peer assessment as an assessment tool, questions may arise about its measurement quality. Among such questions, the extent peer assessment practices adhere to standards of measurement. It has been claimed that new forms of assessment, require new criteria to judge their validity and reliability, since they aim for specific goals and address different aspects of learning. But although new criteria have been formulated, little is known about how they are deployed and operate in actual peer assessment practices. This study intends to explicate the quality criteria relevant to the context of peer assessment. We conducted a survey in vocational education on peer assessment quality criteria applied in classrooms. Fifty-six teachers using peer assessment rated several quality criteria as relevant to their teaching practice. The findings suggest that peer assessment practices entail many of the quality criteria recognized in measurement and evaluation, although in an embedded way: the generic quality criteria are tuned or adapted to the peer assessment setting. The findings also show that peer assessment is very much in the hands of the teacher, who organizes and orchestrates the appraisal process in which students receive clear guidelines to appraise one another's work. Our results indicate that quality criteria hardly differ from the function peer assessment serves in classrooms, either within a summative or formative evaluation context. By gaining insight on the specific criteria of peer assessment and their precise purposes, we believe it becomes possible to help teachers improve its measurement quality. 相似文献

The present study examined children's digital text comprehension of digital text types linear digital text vs hypertext, with or without graphical navigable overviews. We investigated to what extent individual variation in children's comprehension could be explained by lexical quality (word reading efficiency and vocabulary knowledge), cognitive load factors (prior knowledge and working memory), text type and graphical overview. Participants were 93 sixth graders in a within‐subject design. Word reading efficiency, vocabulary knowledge and prior knowledge predicted children's digital comprehension scores, while working memory did not. Reading comprehension was equal for linear text or hypertext. However, the presence of an overview facilitated reading comprehension for readers with lower prior knowledge. It can be concluded that hypertexts with basic digital text features and accompanying comprehension questions are not more difficult for children than linear digital texts, that similar individual factors predict reading comprehension of linear text and hypertext, and that a graphical overview helps when prior knowledge is low. 相似文献

This study compared how lexical quality (vocabulary and decoding) and executive control (working memory and inhibition) predict reading comprehension directly as well as indirectly, via syntactic integration, in monolingual and bilingual fourth grade children. The participants were 76 monolingual and 102 bilingual children (mean age 10 years, SD = 5 months) learning to read Dutch in the Netherlands. Bilingual children showed lower Dutch vocabulary, syntactic integration and reading comprehension skills, but better decoding skills than their monolingual peers. There were no differences in working memory or inhibition. Multigroup path analysis showed relatively invariant connections between predictors and reading comprehension for monolingual and bilingual readers. For both groups, there was a direct effect of lexical quality on reading comprehension. In addition, lexical quality and executive control indirectly influenced reading comprehension via syntactic integration. The groups differed in that inhibition more strongly predicted syntactic integration for bilingual than for monolingual children. For a subgroup of bilingual children, for whom home language vocabulary data were available (n = 56), there was an additional positive effect of home language vocabulary on second language reading comprehension. Together, the results suggest that similar processes underlie reading comprehension in first and second language readers, but that syntactic integration requires more executive control in second language reading. Moreover, bilingual readers additionally benefit from first language vocabulary to arrive at second language reading comprehension. 相似文献

Does Self-directedness in Learning and Careers Predict the Employability of Low-Qualified Employees?
Isabel Raemdonck Harm Tillema Andries de Grip Martin Valcke Mien Segers 《Vocations and Learning》2012,5(2):137-151
Employability has become a key element in sustaining successful vocational careers. The role of self-directedness is considered
paramount in maintaining one’s employability. However, it also requires certain competences on part of employees to invest
in learning and career development. This study examines the influence of self-directedness in learning and career of low-qualified
employees on their employability. In a follow-up study of 284 low-qualified employees, we find that higher levels of self-directedness
in learning and career of employees corresponds with higher chance to be promoted to higher-level job positions (vertical
job mobility). However, no relationship was found between different formats of self-directedness and job retention or horizontal
job mobility of lower qualified personnel. 相似文献

The study explored differences in story comprehension and vocabulary learning in children in native and multicultural kindergarten classrooms when listening to a story read to them by the computer or the teacher. The results showed that children (41 native and 30 immigrant) learned new words, both from listening to their teacher and from listening to the computer. However, immigrant children learned more words and had better story comprehension when the teacher read the story. The study does however show that the computer can provide learning gains for kindergartners working individually and without teacher support with a software program. 相似文献
