How can be explained that early literacy and numeracy share variance? We specifically tested whether the correlation between four early literacy skills (rhyming, letter knowledge, emergent writing, and orthographic knowledge) and simple sums (non-symbolic and story condition) reduced after taking into account preschool attention control, short-term memory, speed of processing, visual-spatial skills, vocabulary, and shared book reading. 228 Dutch native preschoolers (mean age 54.25; SD = 2.12 months) participated. The results revealed that 1) all literacy skills were related to sums (non-symbolic and story condition), 2) rhyming was the strongest predictor of non-symbolic sums, and letter knowledge of sums in story context, 3) visual-spatial skills explained part of the shared variance in the non-symbolic condition and visualspatial skills, vocabulary and short-term memory explained part of the shared variance in sums in story context. Implications for the preschool curriculum and early interventions are discussed. 相似文献

殷商时期青铜器金文大部分都是1—4个字。1字或3字的部分是单一族氏金文,对于这一部分许多学者取得了相当多的研究成果,但是对于2字或4字部分的研究却是非常不足的。我们认为2字金文部分中大部分具有氏族间结合的意义,作为复合族氏金文,其内涵如下:第一,氏族间巩固的结合关系。氏族与氏族间关系紧密有形成新氏族的可能性。第二,氏族间单纯的结合关系。这可认为是为了纪念氏族间发生的某种事件,从而在青铜器上铸刻记下来。我们认为这种结合关系无法实现新氏族的形成。第三,相关联的氏族间的结合。氏族间的结合关系有一定规律,这样的相关联的氏族间有实现结合的可能性。 相似文献

Not all young children benefit from book exposure in preschool age. It is claimed that the ability to hold information in
mind (short-term memory), to ignore distraction (inhibition), and to focus attention and stay focused (sustained attention) may have a moderating effect on children’s reactions to the home literacy environment. In a group of 228 junior kindergarten
children with a native Dutch background, with a mean age of 54.29 months (SD = 2.12 months), we explored therefore the relationship
between book exposure, cognitive control and early literacy skills. Parents filled in a HLE questionnaire (book sharing frequency
and an author recognition checklist as indicator of parental leisure reading habits), and children completed several tests
in individual sessions with the researcher (a book-cover recognition test, PPVT, letter knowledge test, the subtests categories
and patterns of the SON, and cognitive control measures namely digit span of the KABC, a peg tapping task and sustained attention
of the ANT). Main findings were: (1) Children’s storybook knowledge mediated the relationship between home literacy environment
and literacy skills. (2) Both vocabulary and letter knowledge were predicted by book exposure. (3) Short-term memory predicted
vocabulary over and above book exposure. (4) None of the cognitive control mechanisms moderated the beneficial effects of
book exposure. 相似文献

We examined the developmental relations of phonological awareness (PA) and rapid automatized naming (RAN) with reading in a cross-sectional study with 874 Spanish children from Grades 2 to 6. Our main prediction was that the RAN–reading relationship would decrease due to a gradual change in reading strategy, from serial decoding to sight word reading. Therefore, in contrast to most previous studies, we used discrete reading tasks. Serial RAN tasks for objects, colors, digits, and letters were included. First, we examined whether the RAN tasks loaded on the same constructs across time. An alphanumeric and a nonalphanumeric factor were identified, which were invariant over time. In subsequent multigroup structural equation models we found that the PA–reading relationship was low but slightly increased in the higher grades. As predicted, the RAN–reading relationship decreased for words, whereas the relationship remained stable for pseudowords. 相似文献

This study describes the multiple analogical models used to introduce and teach Grade 12 chemical equilibrium. We examine the teacher's reasons for using models, explain each model's development during the lessons, and analyze the understandings students derived from the models. A case study approach was used and the data were drawn from the observation of three consecutive Grade 12 lessons on chemical equilibrium, pre‐ and post‐lesson interviews, and delayed student interviews. The key analogical models used in teaching were: the “school dance”; the “sugar in a teacup”; the “pot of curry”; and the “busy highway.” The lesson and interview data were subject to multiple, independent analyses and yielded the following outcomes: The teacher planned to use the students' prior knowledge wherever possible and he responded to student questions with stories and extended and enriched analogies. He planned to discuss where each analogy broke down but did not. The students enjoyed the teaching but built variable mental models of equilibrium and some of their analogical mappings were unreliable. A female student disliked masculine analogies, other students tended to see elements of the multiple models in isolation, and some did not recognize all the analogical mappings embedded in the teaching plan. Most students learned that equilibrium reactions are dynamic, occur in closed systems, and the forward and reverse reactions are balanced. We recommend the use of multiple analogies like these and insist that teachers always show where the analogy breaks down and carefully negotiate the conceptual outcomes. © 2005 Wiley Periodicals, Inc.

Due to the implementation of a 9‐year integrated curriculum scheme in Taiwan, research on team teaching and web‐based technology appears to be urgent. The purpose of this study was incorporated web‐assisted learning with team teaching in seventh‐grade science classes. The specific research question concerned student performance and attitudes about the teaching method. Two certified science teachers and four classes of the seventh graders participated in this study. It used a mixed methods design, incorporating both quantitative and qualitative techniques. The main data included students’ scores, questionnaires, teachers’ self‐reflections, and the researcher’s interviews with teachers. The results showed that the average final examination scores of students experiencing the experimental teaching method were higher than that of those receiving traditional teaching. The two teaching methods showed significant difference in respect of students’ achievement. The research had limitations because of students’ abilities of data collection, computer use, and discussion, but more than one‐half of the students preferred the experimental method to traditional teaching. However, team teachers would encounter the problems of technology ability, time constraints, and entrance examination pressure. 相似文献
