The focus of this special issue is on the cognitive load underlying processes of interactive knowledge construction in a wide range of instructional multimedia platforms. Multimedia comprehension involves the parallel processing of auditory–verbal and visual–pictorial channels within working memory. By means of integrating multimodal information, students are able to acquire new knowledge. However, the processes of knowledge construction may be dependent on the load a task imposes on the learner's cognitive system. Such cognitive load is determined by prior knowledge, motivation, and processing strategies on the part of the learner as well as on task demands. Other critical factors that should be explored are goal adoption and perspective taking, effects of interactive animation, environmental support, and possibilities of collaboration. 相似文献

In the last decade, ICT use has expanded enormously in most Western countries. In line with this development, we hypothesised
that freshmen at university would not only have mastered more ICT skills, but would also use computers more often than their
counterparts of 5 years previously. To compare students’ opinions and behaviour between 2005 and 2009, responses to two online
questionnaires (N = 714 in 2005 and N = 1529 in 2009) offered at a large university were compared. The main variables of the Technology Acceptance Model (as well
as facilitating factors, study motivation and some contextual variables) were used as predictors to explore the possible changes
between 2005 and 2009 in the mastering of 19 ICT skills, and the frequency of the use of computers for six different tasks.
The results of the study show that freshmen became more proficient in some ICT skills, while proficiency in other skills did
not change or even dropped. Gender is still an important factor to predict ICT skills and the frequency of using computers,
but it is shown that for some skills female students have caught up with their male counterparts. 相似文献

The goal of this longitudinal study was to examine which skills in early literacy determine the development of word recognition, reading comprehension, and spelling in the 2nd grade of the elementary school. A cohort of pupils was followed and tested during the 2nd year of kindergarten and the beginning of the 1st and 2nd grade. It appeared that mainly 2 skills determined the development of word recognition: rapid naming of letters and knowledge of letters. Reading comprehension was predicted to a large extent by vocabulary, rapid naming of letters, letter knowledge, and phonemic awareness. The skills that determined the development of spelling were rapid naming of numbers and letter knowledge. 相似文献

Contemporary science standards stress the importance of highlighting inquiry in the science classroom as one way of learning key concepts. One critical question that needs to be addressed for a range of instructional practices is how opportunities to learn are conceptualized so that students can engage and learn the critical ideas and practices necessary to become scientifically literate. Here I position the ethically‐contested practice of dissection as one instructional practice that needs to be examined in order to see if the learning environment that is created when teachers and students engage in dissection is one that allows students to practice a meaningful science. I argue that the pedagogical value in dissection may not be worth the ethical compromises that surround it. 相似文献

This study investigated the role of cognitive and language skills as predictors of early literacy skills in children with Specific Language Impairment. A range of cognitive and linguistic skills were assessed in a sample of 137 eight-year-old children with SLI at the beginning of the school year, and 6 months later on word decoding and reading comprehension. The cognitive and linguistic measures revealed four factors that were called language, speech, short-term memory, and phonological awareness. Structural equation modeling showed word decoding to be predicted by speech, short-term memory, and phonological awareness, whereas reading comprehension was predicted by word decoding skills and short-term memory. It can be concluded that in children with SLI variations in early word decoding are mostly determined by speech abilities and short-term memory, and to a lesser extent by phonological awareness. Moreover, reading comprehension turns out to be highly dependent on word decoding and short-term memory. 相似文献

This article investigates the multimodal discourses taking place in a primary school computer supported collaborative literacy environment, in which face-to-face talk in pairs is combined with computer-mediated communication. Following a socially mediated model of education, we have taken into account the collaborative process of the participants over time, the privileging processes, in relation to the discourse, afforded by the tasks and tools, and the classroom culture. We describe the contextualized nature of the interaction of children in a CSCL learning environment, by focusing on the intertextual connections that were made between different discourses. This paper highlights, in particular, the intertextual connections between written texts, face-to-face discourse and classroom culture. 相似文献

Research on media success factors is a fragmented field. Definitions, measures, and methods vary, and findings are often inconsistent. In an attempt to fill this perceived research gap, we distilled generic success factors of media products from the literature. Guided by theory and empirical findings, these factors were aggregated to complex concepts, building blocks of success that we further investigated in an exploratory qualitative study. We found that the building blocks are applicable to all types of media, independent of seriality and content types of media products. Subsequently the research question of this article is: Which building blocks of success are most important for media products? To answer this question, we conducted an online survey of 255 media professionals in print, audio-visual, and online media in Austria, Germany and Switzerland. To analyze our data, we deployed qualitative comparative analysis, a method based on set theory that is suitable to investigate complex causality. We conclude that four building blocks are necessary for success: “good” distribution, environmental orientation, form/design, and human resources are preconditions for achieving success in terms of audience market share. In addition, three patterns emerge in the sufficient paths (combinations of building blocks) to success. Which route to success a media product shows can be related to the width of its topical scope and the corresponding projected audience size. 相似文献

The acquisition of reading vocabulary is one of the major challenges for deaf children in bilingual education programs. Deaf children have to acquire a written lexicon that can effectively be used in reading. In this paper, we present a developmental model that describes reading vocabulary acquisition of deaf children in bilingual education programs. The model is inspired by Jiang's model of vocabulary development in a second language (N. Jiang, 2000, 2004a) and the hierarchical model of lexical representation and processing in bilinguals (J. F. Kroll & E. Stewart, 1988). We argue that lexical development in the written language often fossilizes and that many words deaf readers acquire will not reach the final stage of lexical development. We argue that this feature is consistent with many findings reported in the literature. Finally, we discuss the pedagogical implications of the model. 相似文献

Besides phonotactic principles, orthographies entail graphotactic rules for which the reader must convert a phonological representation on the basis of spelling adaptation rules. In the present study, the learnability of such rules will be investigated with reference to Dutch. Although Dutch orthography can be considered highly regular, there are graphotactic rules that change letter sequences in plural noun formation. In a lexical decision experiment, the acquisition and use of such rules were examined. Participants were groups of 31 children from Grade 3 and 34 children from Grade 6, and 25 adults. The results showed that both children and adults are significantly less accurate and slower in recognizing plural word forms which undergo vowel change as a consequence of pluralization. It is concluded that graphotactic rules in Dutch orthography complicate Dutch word identification from an early stage of development and continue to play a complicating role in the word identification process of adult readers. In the discussion it is shown that current models fail to fully explain the processing of graphotactic rules in visual word identification. 相似文献
