Segmenting Texts Into Meaningful Word Groups: Beginning Readers’ Prosody and Comprehension

It was hypothesized that prosodic reading facilitates beginning readers’ comprehension by allowing them to segment the text into meaningful word groups. Two prosodic features of the oral reading of second-grade students were considered: lack of inappropriate pauses and attention to punctuation. To examine the unique contribution of these features to reading comprehension, fluency (speed and accuracy of reading) and vocabulary were controlled. As expected, both prosodic features were significantly related to comprehension, jointly explaining as much variance as fluency. Accordingly, it might be counterproductive to encourage reading speed and accuracy at the expense of prosody.     

Chemistry Teachers’ Knowledge and Application of Models

Teachers’ knowledge and application of model play an important role in students’ development of modeling ability and scientific literacy. In this study, we investigated Chinese chemistry teachers’ knowledge and application of models. Data were collected through test questionnaire and analyzed quantitatively and qualitatively. The result indicated as follows: (1) Chemistry teachers’ knowledge of some known chemistry models was limited; (2) Chemistry teachers preferred those models that were vivid when they chose models; (3) Teachers’ modeling process was incomplete; (4) Teachers adopted a general pattern when applying models in chemistry teaching. The findings have implications for teacher education.     

Slovakian Students’ Knowledge of and Attitudes toward Biotechnology

This study examined university students’ knowledge of and attitudes (n = 378) toward biotechnology in Slovakia, a conservative country where the distribution of genetically engineered products are banned by law. We found a significant positive correlation between attitudes and the level of knowledge; however, although students enrolled in biology courses have better knowledge of biotechnology, their attitudes toward genetic engineering were similar than those of students who do not study biology. Females showed poorer knowledge and lower acceptance of genetically engineered products than did males. Overall, Slovakian students have poor knowledge and numerous misunderstandings about what genetic engineering means, which suggests that science curriculum with respect to this topic should be greatly re‐evaluated and teaching strategies should be improved accordingly.     

An Analysis of the Relationship between Implicit and Explicit Knowledge——the Grammar Study

The discussions about cognition psychology in the field of second language acquisition(SLA) exert great influence on language teaching practice and theoretical research.Interface positions on the role of explicit and implicit knowledge in SLA have led to further exploration by different researchers.This paper,on the basis of previous studies,makes a brief review of the relation ship between implicit and explicit knowledge,focusing on the analysis of interface position and its role in grammar teaching and learning.     

Children’s Orthographic Knowledge and Their Word Reading Skill: Testing Bidirectional Relations

Prominent models of word reading concur that the development of efficient word reading depends on the establishment of lexical orthographic representations in memory. In turn, word reading skills are conceptualised as supporting the development of these orthographic representations. As such, models of word reading development make clear predictions of bidirectional relations between lexical orthographic knowledge and word reading skill. We test these predictions in a longitudinal study of 112 English-speaking children in Grades 2 and 3. At two time points, we assessed lexical orthographic knowledge and three aspects of word reading skill: word reading accuracy, word reading efficiency, and phonological decoding. Consistent with theoretical predictions, we found that earlier word reading accuracy, word reading efficiency, and phonological decoding predicted gains in lexical orthographic knowledge. Contrary to theoretical predictions, lexical orthographic knowledge did not predict gains in any of our measured word reading skills.     

Training Mispronunciation Correction and Word Meanings Improves Children’s Ability to Learn to Read Words

Previous research has suggested that learning to read irregular words depends upon knowledge of a word’s meaning and the ability to correct imperfect decoding attempts by reference to the known pronunciations of a word. In an experimental training study, 84 children ages 5–7 years were randomly assigned to an intervention or control group. Children in the intervention group participated in a 4-week programme in which they were taught to correct mispronunciations of spoken words as well as being taught the meanings of those words. Children in the control group received no additional teaching. The intervention group made significant gains in their ability to correct mispronunciations and to read and define the taught words; these gains also generalised to a comparable set of untaught control words. Children can be taught to correct errors in the pronunciation of irregular words, and this may produce generalised effects on learning to read.     

The Efficacy of Orthographic Rime,Grapheme–Phoneme Correspondence,and Implicit Phonics Approaches to Teaching Decoding Skills

This study compared the efficacy of two decoding skill-based programs, one based on explicit orthographic rime and one on grapheme–phoneme correspondences, to a control group exposed to an implicit phonics program. Children in both explicit decoding programs performed consistently better than the control group in the accuracy with which they read and spelled words covered in the program. Only children in the grapheme–phoneme correspondence program consistently spelled transfer words better than children in the control group. In addition, children in the grapheme–phoneme correspondence group consistently read words more quickly than children in the control group. Children in both explicit decoding programs scored higher than the children in the control group on measures of reading comprehension and oral reading at posttest.     

Elementary Teachers’ Mathematics Subject Knowledge: the Knowledge Quartet and the Case of Naomi

This paper draws on videotapes of mathematics lessons prepared and conducted by pre-service elementary teachers towards the end of their initial training at one university. The aim was to locate ways in which they drew on their knowledge of mathematics and mathematics pedagogy in their teaching. A grounded approach to data analysis led to the identification of a ‘knowledge quartet’, with four broad dimensions, or ‘units’, through which mathematics-related knowledge of these beginning teachers could be observed in practice. We term the four units: foundation, transformation, connection and contingency. This paper describes how each of these units is characterised and analyses one of the videotaped lessons, showing how each dimension of the quartet can be identified in the lesson. We claim that the quartet can be used as a framework for lesson observation and for mathematics teaching development.     

A Framework for Analysis of Teachers’ Geometric Content Knowledge and Geometric Knowledge for Teaching

Current reform-driven mathematics documents stress the need for teachers to provide learning environments in which students will be challenged to engage with mathematics concepts and extend their understandings in meaningful ways (e.g., National Council of Teachers of Mathematics, 2000, Curriculum and evaluation standards for school mathematics. Reston, VA: The Council). The type of rich learning contexts that are envisaged by such reforms are predicated on a number of factors, not the least of which is the quality of teachers’ experience and knowledge in the domain of mathematics. Although the study of teacher knowledge has received considerable attention, there is less information about the teachers’ content knowledge that impacts on classroom practice. Ball (2000, Journal of Teacher Education, 51(3), 241–247) suggested that teachers’ need to ‘deconstruct’ their content knowledge into more visible forms that would help children make connections with their previous understandings and experiences. The documenting of teachers’ content knowledge for teaching has received little attention in debates about teacher knowledge. In particular, there is limited information about how we might go about systematically characterising the key dimensions of quality of teachers’ mathematics knowledge for teaching and connections among these dimensions. In this paper we describe a framework for describing and analysing the quality of teachers’ content knowledge for teaching in one area within the domain of geometry. An example of use of this framework is then developed for the case of two teachers’ knowledge of the concept ‘square’.     

The Efficacy of Multimedia Stories in Preschoolers’ Explicit and Implicit Story Comprehension

Oral language provides a foundation for reading comprehension. Story comprehension is a fundamental oral language skill; it covers making inferences, identifying main ideas, monitoring, perspective-taking, and applying working memory capacity. Complex reasoning and perspective-taking are key factors in deep reading comprehension. Preliterate children’s deeper story comprehension skills can be initial indicators of their later reading comprehension. Thus, the purpose of this research is to investigate preliterate preschool children’s story comprehension skills in detail. This study focuses on the additional multimedia features of digital storybooks and whether they hinder or promote young children’s explicit and implicit comprehension in a small group reading activity. The findings revealed that (a) children in the multimedia-enhanced storybook group outperformed the print storybook group in terms of both explicit and implicit story comprehension, (b) explicit story comprehension was higher than implicit story comprehension for both groups, and (c) the children recalled significantly more story elements and the length of the story retellings was greater with the aid of animated illustrations. The findings indicate that a digital storybook provides close temporal contiguity of text and visuals and may enhance story understanding by concretizing the narration. The study provides evidence that multimedia stories can foster children’s implicit story comprehension and inferential thinking about the content of the story.     

On the Manipulation of the Selectivity of Encoding and Decoding over the Translator’s Subjectivity

The translation activity is a process of the interlinguistic transmission of information realized by the information encoding and decoding.Encoding and decoding,cognitive practices operated in objective contexts,are inevitably of selectivity ascribing to the restriction of contextual reasons.The translator as the intermediary agent connects the original author(encoder)and the target readers(decoder),shouldering the dual duties of the decoder and the encoder,for which his subjectivity is irrevocably manipulated by the selectivity of encoding and decoding.     

Vygotsky’s ‘Thought and Word’

The last chapter of Vygotsky’s last book, Thinking and Speech, is a compressed argument about the construction of consciousness through the internalisation of language. This article comments on Vygotsky’s analysis of the ‘voyage into the interior’ undertaken by oral speech as it is internalised and abbreviated into ‘inner speech’, and then further concentrated as non-verbal thought. The article focuses on the part that literature and especially poetry play in Vygotsky’s argument in this chapter, and suggests that in exploring the condensed semantics of inner speech Vygotsky is implicitly describing how poets turn private thoughts into ‘symbols for others’. It concludes with a commentary on Vygotsky’s use of Mandelshtam’s poem ‘The Swallow’, from which he draws his epigraph.     

Elementary and Middle School Students’ Conceptions of Knowledge,Information, and Truth

Although the study of epistemic beliefs has received growing interest in the past decades, this research tends to focus on high school and undergraduate students, and does not address beliefs about information and truth, concepts that have been regarded as critical for learners in 21st-century educational contexts. In this study, the authors examined 87 elementary and middle school students’ beliefs about the definitions of and relations among knowledge, information, and truth through the use of a graphical and justification task, and addressed the consistency of beliefs across contexts and domains. Results indicated that students tended to regard knowledge, information, and truth as interrelated, and the majority of students described their beliefs as consistent across contexts and domains.     

An Investigation on Experienced Teachers’ Knowledge and Perceptions of Instructional Theories and Practices

Instructional practices in schools have been constantly changing over the years, and educators’ knowledge about these practices is an important factor that influences their effective use. This paper presents an examination of teachers’ knowledge and perception of 24 instructional practices commonly used in the field of education, especially in the field of technology-based teaching and learning. Data from 162 experienced teachers who had enrolled in teacher education courses in two universities were collected from 2005 to 2007. Consistent with the literature, findings suggest that teachers with higher degrees and more teaching experience are aware of and understand more about educational practices. A predictive model was developed from this study.     

Perfectionism,Implicit Theories of Intelligence,and Taiwanese Eighth-Grade Students’ Academic Engagement

ABSTRACT

The authors attempted to examine how Taiwanese junior high school students’ perfectionistic tendencies and implicit theories of intelligence were related to their academic emotions and approach versus avoidance self-regulation, and to determine differences in contingent self-worth, emotions, and self-regulation among students with different subtypes of perfectionism. A total of 481 8th-grade Taiwanese students completed a self-reported survey assessing their perfectionistic tendencies, implicit theories of intelligence, academic emotions, behavioral self-regulation, and use of self-handicapping strategies. Results suggested that adaptive perfectionism enabled adolescents to experience positive emotions and to engage in behavioral self-regulation, whereas maladaptive perfectionism was positively associated with negative emotions and self-handicapping. In addition, the incremental theory of intelligence predicted positive affect and constructive coping. By contrast, the entity theory was positively correlated with negative emotions and self-handicapping. The authors also documented profiles of students with different perfectionistic tendencies. Findings showed that in general adaptive perfectionists displayed the healthiest emotions and self-regulatory styles. Implications for education and further research are discussed.
