Retention by “fast” and “slow” learners

Four experiments were conducted to replicate and extend the findings by Shuell and Keppel (1970) as well as others, that when properly equated for original learning, “fast” and “slow” learners have parallel forgetting curves. In Experiments I and II, the Shuell-Keppel findings, originally demonstrated on American students learning lists of words, were replicated on samples of Nigerian students. In Experiments III and IV, Nigerian and American students, respectively, learned poems to a criterion of 75–90% correct and were tested for retention. In all studies, “fast” and “slow” learners were brought to a similar learning criterion, with the result that their forgetting curves were parallel.     

English- and Chinese-learning infants map novel labels to objects and actions differently

Research based on naturalistic and checklist methods has revealed differences between English and Chinese monolingual children in their trajectories of learning nouns and verbs. However, studies based on controlled laboratory designs (e.g., Imai et al., 2008) have yielded a more mixed picture. Guided by a multidimensional view of word learning (in which different mechanisms are weighted and recruited to different extents over development), we examined English- and Mandarin-learning infants' (n = 128) ability to map novel labels to unfamiliar actions and objects. Findings reveal cross-linguistic variations in the mapping of words to actions versus objects that are consistent with those found previously with naturalistic and checklist methods. Specifically, English learners were able to map novel labels to both actions and objects at 18 months but to neither actions nor objects at 14 months. In an identical experimental paradigm, Mandarin learners at both 14 and 18 months of age were able to map novel labels to actions but not to objects. Similar patterns were found when infants were grouped based on their vocabulary size. Combined results lend support for a dynamic view of word learning that take into account multiple mechanisms interacting across developmental time with important cultural constraints.     

Profiling Perceptual Learning Styles of Chinese as a Second Language Learners in University Settings

This study revisited Reid’s (1987) perceptual learning style preference questionnaire (PLSPQ) in an attempt to answer whether the PLSPQ fits in the Chinese-as-a-second-language (CSL) context. If not, what are CSL learners’ learning styles drawing on the PLSPQ? The PLSPQ was first re-examined through reliability analysis and confirmatory factor analysis (CFA) with 224 CSL learners. The results showed that Reid’s six-factor PLSPQ could not satisfactorily explain the CSL learners’ learning styles. Exploratory factor analyses were, therefore, performed to explore the dimensionality of the PLSPQ in the CSL context. A four-factor PLSPQ was successfully constructed including auditory/visual, kinaesthetic/tactile, group, and individual styles. Such a measurement model was cross-validated through CFAs with 118 CSL learners. The study not only lends evidence to the literature that Reid’s PLSPQ lacks construct validity, but also provides CSL teachers and learners with insightful and practical guidance concerning learning styles. Implications and limitations of the present study are discussed.     

STIMULUS OVERSELECTIVITY IN LEARNING DISABLED CHILDREN

Stimulus overselectivity, a phenomenon exhibited by autistic and institutionalized retarded individuals, was examined in mildly handicapped and nonhandicapped public school children. Subjects were 16 young, educable mentally retarded, 16 learning disabled, 15 nonhandicapped first- and second-graders, and 16 older, educable retarded students. The children were trained on a 3-component visual discrimination task and then tested on individual elements to determine which element or elements were controlling subject responses. Nine of the young educable mentally retarded children and eight of the learning disabled students showed some overselectivity. The majority of overselective retarded children were controlled by only one of the three components of the training cue, whereas the majority of the overselective learning disabled children responded to the discrimination task on the basis of two of the three components. No overselectivity was exhibited by the nonhandicapped students. All three cue components were also functional in controlling the responding of 14 of the 16 older retarded students, but two children were under the control of only one cue. The research indicated that in terms of overselectivity, learning disabled children respond more like young, mildly retarded children than they do like nonhandicapped ones. The demonstration of stimulus overselectivity in a sizable portion of a learning disabled sample may have implications for a more empirically based approach to this handicapped population.     

Towards effective partnerships in a collaborative problem‐solving task

Background Collaborative learning is recognized as an effective learning tool in the classroom. In order to optimize the collaborative learning experience for children within a collaborative partnership, it is important to understand how to match the children by ability level, and whether assigning roles within these dyads is beneficial or not. Aims The current study investigated the effect of partnering children with different task‐specific abilities and assigning or not assigning helping roles within the dyads on the quality of talk used in a collaborative learning task. Sample The participants in this study comprised 54 year 6 pupils from a Western Sydney government primary school (boys=26, girls=28). The ages ranged from 10 years 10 months to 12 years 4 months with a mean age of 11 years 4 months. Method The children were formed into 27 single sex dyads of low–middle‐ and low–high‐ability partnerships. In half of each of these dyads the higher ability partner was asked to help the lower ability partner, which was compared with just asking partners to work together. The quality of talk used by the dyads while working collaboratively on the problem‐solving task was analysed using a language analysis framework developed by Mercer and colleagues (e.g. Littleton et al., 2005 ; Mercer, 1994, 1996 ). Results Results of this study found that children who worked collaboratively in the low–middle‐ability dyad condition demonstrated significantly more high‐quality exploratory talk than those in the low–high‐ability dyad condition. Although there was no significant difference between dyads who were assigned roles and those who were asked to work together, there was an interaction trend which suggests that low–high‐ability dyads, who were given the roles of helper and learner, showed more exploratory talk than dyads who were asked just to work together. Conclusion Mercer's re‐conceptualization of Vygotsky's Zone of Proximal Development (ZPD) in terms of the Intermental Development Zone (IDZ), which is reliant on constructive challenging discourse, can potentially provide a platform upon which all learners in the classroom can benefit from collaborative learning experiences.     

Comorbidity of Attention Deficit Hyperactive Disorder (ADHD) and major depression in primary school children

The study investigated comorbid Attention-Deficit/Hyperactivity Disorder (ADHD) and depression in a sample of rural primary school children in Limpopo Province, South Africa. A total of 320 learners participated in this study of whom 160 learners had teacher and parent identified ADHD symptoms (females?=?50%; age range 6–14 years). All the learners took the Beck Depression Youth Inventory, second edition. Data were analysed applying ANOVA to investigate the possible differences between and within age, gender, and ADHD subtype group differences in depression symptomatology. Results indicated no statistically significant differences in the scores on the depression scale between the children with ADHD as identified by parents and teachers and the comparison group peers.     

The comprehension skills of children learning English as an additional language

Background Data from national test results suggests that children who are learning English as an additional language (EAL) experience relatively lower levels of educational attainment in comparison to their monolingual, English‐speaking peers. Aims The relative underachievement of children who are learning EAL demands that the literacy needs of this group are identified. To this end, this study aimed to explore the reading‐ and comprehension‐related skills of a group of EAL learners. Sample Data are reported from 92 Year 3 pupils, of whom 46 children are learning EAL. Method Children completed standardized measures of reading accuracy and comprehension, listening comprehension, and receptive and expressive vocabulary. Results Results indicate that many EAL learners experience difficulties in understanding written and spoken text. These comprehension difficulties are not related to decoding problems but are related to significantly lower levels of vocabulary knowledge experienced by this group. Conclusions Many EAL learners experience significantly lower levels of English vocabulary knowledge which has a significant impact on their ability to understand written and spoken text. Greater emphasis on language development is therefore needed in the school curriculum to attempt to address the limited language skills of children learning EAL.     

Numerical morphology supports early number word learning: Evidence from a comparison of young Mandarin and English learners

Previous studies showed that children learning a language with an obligatory singular/plural distinction (Russian and English) learn the meaning of the number word for one earlier than children learning Japanese, a language without obligatory number morphology (Barner, Libenson, Cheung, & Takasaki, 2009; Sarnecka, Kamenskaya, Yamana, Ogura, & Yudovina, 2007). This can be explained by differences in number morphology, but it can also be explained by many other differences between the languages and the environments of the children who were compared. The present study tests the hypothesis that the morphological singular/plural distinction supports the early acquisition of the meaning of the number word for one by comparing young English learners to age and SES matched young Mandarin Chinese learners. Mandarin does not have obligatory number morphology but is more similar to English than Japanese in many crucial respects. Corpus analyses show that, compared to English learners, Mandarin learners hear number words more frequently, are more likely to hear number words followed by a noun, and are more likely to hear number words in contexts where they denote a cardinal value. Two tasks show that, despite these advantages, Mandarin learners learn the meaning of the number word for one three to six months later than do English learners. These results provide the strongest evidence to date that prior knowledge of the numerical meaning of the distinction between singular and plural supports the acquisition of the meaning of the number word for one.     

Development and validation of the Achievement Goal Scale for Youth Sports

ObjectiveThe objective was to develop and validate an achievement goal scale for young athletes that was aligned with the 2 (mastery/ego)×2 (approach/avoidance) achievement goal framework.MethodA total of 1675 male and female athletes ranging in age from 9 to 14 years participated in the AGSYS scale development and validation phases. Items having a readability level of grade 4 (age 9) or below were written and evaluated in a series of studies to assess the reliability, factorial validity, and construct validity of the Mastery and Ego scales.DesignBoth correlational and experimental methods were used to assess reliability and validity.ResultsExploratory and confirmatory factor analyses demonstrated factorial validity in samples of 9–10-, 11–12-, and 13–14-year-old athletes, and the subscales correlated in a predicted fashion with one another, with other sport and academic goal orientation measures and with several other theoretically relevant variables, including coach-initiated motivational climate, competitive trait anxiety, sport enjoyment, motivation, and self-esteem. Scores also changed significantly in response to a motivational climate coach intervention.ConclusionThe Achievement Goal Scale for Youth Sports (AGSYS) appears to be a reliable and valid measure of achievement goal approach orientations in children between the ages of 9 and 14 years. We were not successful in developing corresponding avoidance goal orientation scales that were not highly correlated, raising the possibility that children do not cognitively differentiate between mastery-avoidance and ego-avoidance orientations.     

Sensitivity to sampling in Bayesian word learning

We report a new study testing our proposal that word learning may be best explained as an approximate form of Bayesian inference (Xu & Tenenbaum, in press). Children are capable of learning word meanings across a wide range of communicative contexts. In different contexts, learners may encounter different sampling processes generating the examples of word-object pairings they observe. An ideal Bayesian word learner could take into account these differences in the sampling process and adjust his/her inferences about word meaning accordingly. We tested how children and adults learned words for novel object kinds in two sampling contexts, in which the objects to be labeled were sampled either by a knowledgeable teacher or by the learners themselves. Both adults and children generalized more conservatively in the former context; that is, they restricted the label to just those objects most similar to the labeled examples when the exemplars were chosen by a knowledgeable teacher, but not when chosen by the learners themselves. We discuss how this result follows naturally from a Bayesian analysis, but not from other statistical approaches such as associative word-learning models.     

The test–retest reliability of the latent construct of executive function depends on whether tasks are represented as formative or reflective indicators

This study investigates the test–retest reliability of a battery of executive function (EF) tasks with a specific interest in testing whether the method that is used to create a battery-wide score would result in differences in the apparent test–retest reliability of children’s performance. A total of 188 4-year-olds completed a battery of computerized EF tasks twice across a period of approximately two weeks. Two different approaches were used to create a score that indexed children’s overall performance on the battery—i.e., (1) the mean score of all completed tasks and (2) a factor score estimate which used confirmatory factor analysis (CFA). Pearson and intra-class correlations were used to investigate the test–retest reliability of individual EF tasks, as well as an overall battery score. Consistent with previous studies, the test–retest reliability of individual tasks was modest (rs ≈ .60). The test–retest reliability of the overall battery scores differed depending on the scoring approach (r_mean = .72; r_{factor_score} = .99). It is concluded that the children’s performance on individual EF tasks exhibit modest levels of test–retest reliability. This underscores the importance of administering multiple tasks and aggregating performance across these tasks in order to improve precision of measurement. However, the specific strategy that is used has a large impact on the apparent test–retest reliability of the overall score. These results replicate our earlier findings and provide additional cautionary evidence against the routine use of factor analytic approaches for representing individual performance across a battery of EF tasks.     

What you learn is what you see: using eye movements to study infant cross-situational word learning

Recent studies show that both adults and young children possess powerful statistical learning capabilities to solve the word-to-world mapping problem. However, the underlying mechanisms that make statistical learning possible and powerful are not yet known. With the goal of providing new insights into this issue, the research reported in this paper used an eye tracker to record the moment-by-moment eye movement data of 14-month-old babies in statistical learning tasks. Various measures are applied to such fine-grained temporal data, such as looking duration and shift rate (the number of shifts in gaze from one visual object to the other) trial by trial, showing different eye movement patterns between strong and weak statistical learners. Moreover, an information-theoretic measure is developed and applied to gaze data to quantify the degree of learning uncertainty trial by trial. Next, a simple associative statistical learning model is applied to eye movement data and these simulation results are compared with empirical results from young children, showing strong correlations between these two. This suggests that an associative learning mechanism with selective attention can provide a cognitively plausible model of cross-situational statistical learning. The work represents the first steps in using eye movement data to infer underlying real-time processes in statistical word learning.     

TEACHING EARLY READING SKILLS TO CHILDREN WITH AUTISM USING MIMIOSPROUT EARLY READING

A number of studies have demonstrated positive outcomes for typical learners from the internet‐based reading program, MimioSprout® Early Reading (MER). In the present study, a preliminary evaluation of MER was conducted with four children with autism who attended an applied behavior analysis educational program in a school setting. The primary aim was to investigate whether it would be feasible to use MER with children with autism and whether any adaptations to the standard teaching procedure would be needed. A secondary aim was to investigate whether completing MER would improve early reading skills. When additional discrete‐trial table top activities were designed to supplement each child's progress, every child was able to complete all 80 lessons and showed similar correct performance to that reported for typically developing learners. Results from a standardized test of reading ability showed an improvement in word recognition reading age for all children from 14 months to more than three years over the 14 weeks of teaching. A follow‐up test showed that gains were maintained eight weeks after the end of the intervention. MER can be successfully used with children with autism and can improve their early reading skills.

Vicarious Resilience: An Exploration of Teachers and Children’s Resilience in Highly Challenging Social Contexts

This study explores the formulation of vicarious resilience as a useful concept in the middle school age school educational arena. It addresses the question of how teachers who work with learners who experienced dislocation and adversity are affected by the children’s stories of resilience. It focuses on the teachers’ interpretations of their learners’ stories, and how they make sense of the impact these stories have had on their lives. Twenty-one teachers who work in accelerated learning programs in Cali, Colombia, were interviewed about their perceptions of their learners’ overcoming of adversity. Data were analyzed through the Consensual Qualitative Research (CQR) methodology to describe the themes that speak about the effects of witnessing how learners coped constructively with adversity. These themes are discussed to advance the concept of vicarious resilience and how it can contribute to sustaining and empowering teachers dealing with challenging children and trauma.     

Learning of letter names follows similar principles across languages: Evidence from Hebrew

Letter names play an important role in early literacy. Previous studies of letter name learning have examined the Latin alphabet. The current study tested learners of Hebrew, comparing their patterns of performance and types of errors with those of English learners. We analyzed letter-naming data from 645 Israeli children who had not begun formal reading instruction: a younger group (mean age 5 years 2 months) and an older group (mean age 6 years 2 months). Children's errors often involved letters with similar shapes or letters adjacent to one another in the alphabet. Most Hebrew letter names are not very similar to one another phonologically, and there were fewer phonologically based confusions than in English. We found both general frequency effects and frequency effects that reflected the letters in individual children's names. On average, girls knew more letter names than did boys. The results suggest that letter name learning follows similar principles across languages.     

Learning from Worked-Out Examples: A Study on Individual Differences

The goal of this study was to Investigate individual differences in learning from worked-out examples with respect to the quality of self-explanations. Restrictions of former studies (e.g., lacking control of time-on-task) were avoided and additional research questions (e.g., reliability and dimensionality of self-explanation characteristics) were addressed. An investigation with 36 university freshmen students of education working in individual sessions was conducted. The domain was probability calculation. Prior knowledge and the quality of self-explanations (protocols of the individuals' thinking aloud) were assessed as predictors of learning. A post-test was employed to measure the learning gains as the dependent variable. The following main results were obtained. Most self-explanation characteristics could be regarded as relatively stable person characteristics. The individual differences in the quality of self-explanations were, however, found to be multidimensional. Most Important, even when controlling for time-on-task (quantitative aspect), learning gains could be substantially predicted by qualitative differences of self-explanation characteristics. In particular, successful learners tended to employ more prlnciplebased explanations, more explication of operator-goal combinations, and more anticipative reasoning. In addition, there were two types of effective learners, labeled anticipative reasoners and principle-based explainers.     

A developmental study of decay rate in long-term memory

The decay rate of the long-term memory trace was studied in children and adolescents of different ages, for different degrees of learning, using visual material which was not easily verbalized and a recognition procedure which permitted the application of decision theory.Groups of children and adolescents were tested, the ages being 5–6, 7–8, 10–11, and 15–16 years. Each subject was shown 280 pictures in divided sessions. During the learning sessions, some pictures were shown only once; others, two or four times. All Ss were tested for successive retention sessions 2, 5, 10, 20 and 49 weeks after the last learning session. Different portions of the originally learned material, with new material interspersed, were used in each retention sessions.The results suggest that when degree of learning is controlled, the rate at which items are lost from memory is invariant across ages, even though recognition was better the older the children.     

Avoiding misinterpretations of Piaget and Vygotsky: Mathematical teaching without learning,learning without teaching,or helpful learning-path teaching?

This article provides an overview of some perspectives about special issues in classroom mathematical teaching and learning that have stemmed from the huge explosion of research in children's mathematical thinking stimulated by Piaget. It concentrates on issues that are particularly important for less-advanced learners and for those who might be having special difficulties in learning mathematics. A major goal of the article is to develop a framework for understanding what effective mathematics teaching and learning is, because doing so is so important for struggling students and for research about them. Piaget's research had a fundamental influence on the on-going tension between understanding and fluency in the classroom, supporting efforts toward increasing understanding. But in some countries, misinterpretations of Piaget led to practices that are counterproductive for children, especially struggling learners. Such misinterpretations are identified and a more balanced approach that also draws on Vygotsky is described—a learning-path developmentally-appropriate learning/teaching approach.     

汉语婴儿词汇学习的注意偏好

婴儿的动、名词词类学习存在跨文化差异,但是很少研究从注意偏好角度解释这类差异。本研究利用习惯化范式考察汉语婴儿在6-8个月和17-19个月时对事件中人物,动作和物体的区分。结果发现,6-8个月的婴儿仅能区分动作变化,对人物和物体无法区分,而17-19个月的婴儿对三类变化均可以区分。本研究提供了婴儿早期注意偏好发展的实验依据,同时为儿童早期单词获得提供了新的理论基础。
