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

Children's spelling development is often described by researchers and educators as proceeding through a series of stages. Two properties of stages were analyzed in this study. If spelling development can be characterized by stages, then it should be possible to observe qualitatively different spellings at different points in development. In addition, spellings within a point of development must be consistent. Spelling samples were obtained from stories written by children in first through sixth grade. Stage classifications of spellings for (a) silent -e long vowel words (e.g., bake), and (b) regularly affixed past tense words phonologically represented as /t/ (e.g., helped), /d/ (e.g., opened), and /ed/ (e.g., listed) were analyzed. Little evidence was found for either predicted qualitative differences in stage classification of errors or in stage constancy across grades. Implications for theories of spelling development and instructional practice are discussed. 相似文献

There has been much discussion about whether certain aspects of human learning depend on the abstraction of rules or on the acquisition of frequency-based knowledge. It has usually been agreed, however, that the spelling of morphological patterns in English (e.g., past tense -ed) and other languages is based on the acquisition of morphological rules, and that these rules take a long time to learn. The regular plural -s ending seems to be an exception: Even young children can spell this correctly, even when it is pronounced /z/ (as in bees). Reported here are 3 studies that show that 5- to 9-year-old children and adults do not usually base their spellings of plural real-word and pseudo-word endings on the morphological rule that all regular plurals are spelled with -s. Instead, participants appeared to use their knowledge of complex but untaught spelling patterns, which is based on the frequency with which certain letters co-occur in written English. 相似文献

4 experiments examined 3- and 4-year-olds' interpretations of novel words applied to familiar objects in the sentence frame, "This Y is X," where X is a novel word, and Y is a familiar basic-level count noun (e.g., "dog", "cup"). These novel words are ambiguous and could be interpreted either as proper names (e.g., "Fred") or as adjectives/mass nouns (e.g., "red"/"lead"). The experiments addressed 2 questions. First, do children appreciate that the words can be construed either as proper names referring to individuals or as adjectives/mass nouns referring to salient properties/material kinds? The results showed that children could easily make either interpretation. Second, what factors affect children's tendency to make either a proper name or an adjective/mass noun interpretation? In the experiments, children learned the novel words for a range of animals and artifacts. Most children who learned the words for typical pets (e.g., a bird) made proper name interpretations, as did the majority of those who learned the words for certain non-pet animals (e.g., a caterpillar) described as possessed by someone, but only about half of those who learned the words for such non-pet animals not so described. Very few children who learned the words for either simple (e.g., a shoe) or complex (e.g., a boat) artifacts made proper name interpretations. The results provide clear evidence of the role of semantic information in constraining children's interpretation of a novel word, and they help to refine an understanding of what counts as a nameable individual for preschoolers. 相似文献

On Wooden Pillows: Multiple Classification and Children''s Category-based Inductions 总被引：6，自引：0，他引：6
Previous research has indicated that preschoolers do not distinguish between properties that are generalizable within a given category and those that are not. 2 possible general constraints on children's cognition are proposed to account for these findings. 3 studies are reported that argue against the presence of such general constraints. We examine preschoolers' understanding of the properties associated with material (e.g., wood, cotton) and object (e.g., chair, pillow) categories. In Study 1, subjects consistently made inductions based on the material compositions of items when asked to predict texture and fragility. In Study 2, the same subjects judged that items that shared material would share an unfamiliar dispositional property (e.g., gets sodden in water), but items that shared object kind would share a novel functional property (e.g., used for accelerating). Study 3 tested a younger sample of 3-year-olds and found the same sensitivity to category type, albeit with larger individual differences. By age 3, children use different modes of categorization to generalize different kinds of phenomena. These results argue against general limitations on children's abilities to use categories to make inductions. Even when children lack specific theoretical knowledge, the ability to organize phenomena into domains allows children to recognize which categories are relevant in different situations. This understanding can provide a basis for the development of more specific theories. 相似文献

Teachers’ homework follow‐up practices, the in‐class strategies teachers use to monitor their students’ homework assignments, have an impact on their students’ homework behaviors and academic achievement. The current study explored the perspectives of middle school mathematics teachers on the three domains of homework follow‐up: the practices used in class, the purposes of each practice, and the aspects that may influence this process. Data were collected from two data sources (i.e., focus groups and classroom observations) and were analyzed using thematic analysis. The findings showed that teachers monitored homework either using a single strategy or a combination of strategies (e.g., checking homework completion and providing individual feedback) linked to a specific purpose (e.g., promote students’ involvement). The teachers also reported that they were under certain constraints when they delivered homework follow‐up practices (e.g., pressure to follow the curriculum), so their practices’ effectiveness sometimes can be compromised. Implications for practice are discussed. 相似文献

Using schema theory as a framework, we view learning as an active, constructive process. It is affected not only by learners' internal knowledge structures, but by the external constraints of the learning environment as well (Kozma, 1991). This article examines how different internal learner characteristics (e.g., prior knowledge, self efficacy and interest) and different external constraints (e.g., learner control, instructional design and level of control) influence the learning process. Specifically, we address learning from a variety of multimedia environments such as video, hypertexts, kiosks and other hypermedia within a schema theoretic approach that incorporates a constructivist view. 相似文献

Age-related Asynchrony of Knowledge and Action 总被引：1，自引：0，他引：1
Children's ability to act in accordance with rules was assessed in 2 experiments. Experiment I included 66 children, aged 31, 33.5, or 36 months, who performed 2 tasks. In a forced-choice, deductive sorting task, children were told 2 rules (if-then statements) and then required to use the rules to sort items. A knowledge task tested children's knowledge about which rule's antecedent condition held true for each item. Rules were either based on natural categories (e.g., vehicles vs. musical instruments) or ad hoc categories (e.g., things found inside the house vs. things found outside). Children in the 2 younger age groups performed better on the knowledge task than on the sorting task. The 36-month-olds performed equally well on both tasks. In Experiment 2, groups of 12 32.25-month-olds received either the knowledge task, the sorting task, or a mnemonically supported version of the sorting task. The group that received the knowledge task performed better than the other groups, which did not differ. This result undermines the possibility that differential performance on the knowledge and sorting tasks is due to a difference in memory demand. Taken together, the results of Experiments 1 and 2 imply a relatively rapid, age-related change culminating in the ability to execute systematically rules that require access to extant knowledge. 相似文献

Generic sentences (e.g., "Birds lay eggs") convey generalizations about entire categories and may thus be an important source of knowledge for children. However, these sentences cannot be identified by a simple rule, requiring instead the integration of multiple cues. The present studies focused on 3- to 5-year-olds' (N = 91) use of morphosyntactic cues--in particular, on whether children can (a) interpret indefinite singular noun phrases (e.g., "a strawberry") as generic and (b) use a verb's tense and aspect (e.g., "A bat sleeps/slept/is sleeping upside down") to determine whether its subject noun phrase is generic. Children demonstrated sensitivity to both cues. Thus, solving the in-principle problem of identifying generics may not be beyond the reach of young children's comprehension skills. 相似文献

In Study 1, English-speaking 3- and 4-year-olds heard a novel adjective used to label one of two objects and were asked for the referent of a different novel adjective. Children were more likely to select the unlabeled object if the two adjectives appeared prenominally (e.g., "a very DAXY dog") than as predicates (e.g., "a dog that is very DAXY"). Study 2 revealed that this response occurred only when both adjectives were prenominal. Study 3 replicated Study 1 with Hebrew-speaking 3- and 4-year-olds, even though in Hebrew both types of adjectives appear postnominally. Preschoolers understand that prenominal adjectives imply a restriction of the reference of nouns, and this knowledge motivates a contrastive pragmatic inference regarding the referents of different prenominal adjectives. 相似文献

Truisms have the disadvantage that by dulling the senses they obscure the truth. Almost nobody will become alarmed when told that in times of continuity the future equals the past. Only a few will become aware that from this follows that in times of socio-cultural change the future will not be like the past... At any moment we are free to act toward the future we desire. In other words, the future will be as we wish and perceive it to be. This may come as a shock only to those who let their thinking be governed by the principle that demands that only the rules observed in the past shall apply to the future. For those the concept of change is inconceivable, for change is the process that obliterates the rules of the past (Von Foerster, 1972). 相似文献

An IRT‐based sequential procedure is developed to monitor items for enhancing test security. The procedure uses a series of statistical hypothesis tests to examine whether the statistical characteristics of each item under inspection have changed significantly during CAT administration. This procedure is compared with a previously developed CTT‐based procedure through simulation studies. The results show that when the total number of examinees is fixed both procedures can control the rate of type I errors at any reasonable significance level by choosing an appropriate cutoff point and meanwhile maintain a low rate of type II errors. Further, the IRT‐based method has a much lower type II error rate or more power than the CTT‐based method when the number of compromised items is small (e.g., 5), which can be achieved if the IRT‐based procedure can be applied in an active mode in the sense that flagged items can be replaced with new items. 相似文献

This study examines the discursive practice of participation in an elementary classroom community aiming towards collective meaning making and joint creation of knowledge. The theoretical and methodological basis of the study is shaped by the sociocultural and sociolinguistic approaches. Through examining the communicative practices and discursive roles of the students and the teacher, the study highlights the participation rights and responsibilities of classroom members and demonstrates how these shape the location and nature of knowledge constructed during a lesson. The empirical data for this study emerge from a Finnish third grade class consisting of seventeen students. Detailed, multi-level analyses were carried out on transcribed video-recordings of classroom interactions located within the contexts of Collective problem-solving in mathematics, Group investigation in science and Open-ended dialogue in philosophy. The results show that the cultural rules for communicative participation in this classroom provided the students with a space to take authority in cognitive work, whereas the teachers responsibility was more directed to the management of interactional practices. The nature of knowledge negotiated during the lessons was by and large based upon view sharing and defining, as well as asking for and providing evidence, instead of mere information exchange. The study also shows that the communicative roles and responsibilities of the classroom members differed across the learning situations. Intentions of collective meaning-making did not always result in multilateral interactions that would invite all classroom members into active participation. Moreover, challenges were identified in the integration and application of the participants personal histories and experiences as resources for joint meaning-making. In all, the study shows how the discursive norms of the classroom can be aligned with supporting active participation and collective creation of knowledge, but can also be counterproductive in these domains. 相似文献

In English, some words sound the same but are distinguished by silent written markers of their morphological status, as in plurals (e.g., cities), singular possessives (e.g., city’s) and plural possessives (e.g., cities’). We examined undergraduates’ ability to correctly omit or position apostrophes in these three word types before and after a 3-week intervention that focused on the conceptual bases for plurality and possession, as well as their associated spelling rules. Pre-test spelling was imperfect for plurals and poor for possessives, especially plural possessives. Abstract understanding of plurality and possession, measured in a morphological awareness task, was also relatively poor. The intervention resulted in significant but imperfect improvement on all tasks, with post-test morphological awareness predicting post-test spelling of plurals and possessives, even after controls for general spelling ability. Control participants showed no change. We suggest that adults’ difficulty in spelling possessives stems from a shaky grasp of the underlying morphological concepts, and we discuss possibilities for future intervention. 相似文献

ABSTRACT— Teaching others effectively may rely on knowledge about the mind as well as self-control processes. The goal of this investigation was to explore the role of theory of mind (ToM) and executive function (EF) in children's developing teaching skills. Children 3.5–5.5 years of age ( N = 82) were asked to teach a confederate learner how to play a board game and were administered multitask batteries of ToM and EF with mental age, sex, and memory capacity as controls. There was a developmental increase in children's teaching skills (e.g., older children taught longer, explained more rules, and used more strategies when teaching). Examined separately, both ToM and EF explained unique variance in teaching skills over and above controls. Taken together, EF was a significant predictor of teaching efficacy over and above ToM and controls, whereas the same did not hold true for ToM. These results suggest that ToM may be a necessary prerequisite for teaching to occur; however, EF skills appear to play a vital role in children's teaching efficacy. 相似文献

This paper proposes a set of methods and a framework for evaluating, modeling, and predicting group interactions in computer‐mediated communication. The method of sequential analysis is described along with specific software tools and techniques to facilitate the analysis of message–response sequences. In addition, the Dialogic Theory and its assumptions are presented to establish a theoretical framework and guide to using sequential analysis in computer‐mediated communication research. Step‐by‐step instructions are presented to illustrate how sequential analysis can be used to measure the way latent variables (e.g., message function, response latency, communication style) and exogenous variables (e.g., gender, discourse rules, context) affect how likely a message is to elicit a response, the types of responses elicited by the message, and whether or not the elicited sequence of responses (e.g., claim → challenge → explain) mirror the processes that support group decision‐making, problem‐solving, and learning. 相似文献

These studies investigated two hundred and forty-four 24- and 30-month-olds' sensitivity to generic versus nongeneric language when acquiring knowledge about novel kinds. Toddlers were administered an inductive inference task, during which they heard a generic noun phrase (e.g., "Blicks drink milk") or a nongeneric noun phrase (e.g., "This blick drinks milk") paired with an action (e.g., drinking) modeled on an object. They were then provided with the model and a nonmodel exemplar and asked to imitate the action. After hearing nongeneric phrases, 30-month-olds, but not 24-month-olds, imitated more often with the model than with the nonmodel exemplar. In contrast, after hearing generic phrases, 30-month-olds imitated equally often with both exemplars. These results suggest that 30-month-olds use the generic/nongeneric distinction to guide their inferences about novel kinds. 相似文献
