A potential for learning probability in young children

Sixty-one children, from 4 to 11 years old, were presented with two sets, each containing blue and yellow elements. Each time, one colour was pointed out as the payoff colour (POC). The child had to choose the set from which he or she would draw at random a POC element in order to be rewarded. The sets were of varying sizes with different proportions of the two colours. The problem was to select the higher of the two probabilities. Three kinds of materials were used: Pairs of urns with blue and yellow beads, pairs of roulettes divided into blue and yellow sectors, and pairs of spinning tops, likewise divided into two colours.Roughly around the age of six, children started to select the greater of the two probabilities systematically. The dominant error was selecting the set with the greater number of POC elements. Verbal concepts of probability and chance were explored and some egocentric thought processes were described. The study indicates that probability concepts could be introduced into school teaching even in the first grades. The deterministic orientation in the instruction for young ages should be attenuated, permitting concepts of uncertainty right from the beginning.     

Täuschungshandlungen im Sport

Experimental studies on the head fake in basketball showed that participant’s responses in a pass direction identification task were delayed for incongruent compared to congruent directions of the players gaze and pass (so-called head fake effect). In these studies on the head fake effect, static pictures were presented and responses on the pass direction were given with a simple key press. The present study examines whether an increase in the response complexity affects the head fake effect and whether it can also be transferred to the presentation of dynamic stimuli. In experiment 1, participants were presented with static pictures of a basketball player who passes a ball to the left or to the right. The player’s gaze direction was either oriented in the direction of the intended pass or in the opposite direction (i.?e., a head fake). The participants were asked to respond as quickly as possible to the pass direction and to ignore the gaze direction. Participants gave responses by pressing a key (simple response) or by executing a quasirealistic defense movement (complex response). Response complexity was blocked. In experiment 2, videos replaced the static stimuli. The responses were only given with the complex, full body movement. Results show that the head fake effect is independent of response complexity and that it can also be found when presenting dynamic stimuli.     

Misconceptions about Motion: Development and Training Effects

2 experiments were performed to examine whether children and adults possess a single-object/single-motion intuition. This intuition involves the view that because all parts of a rigid object move together, they all must move at the same speed. We found that third graders, sixth graders, ninth graders, and adults all responded in accord with this intuition. On problems where the intuition led to errors, a large majority of subjects of all ages answered incorrectly. On problems where it led to successful performance, subjects answered more accurately than on problems where the intuition was not applicable. In addition, the specific errors were those that the intuition yielded, and the intuition fit individual patterns of performance. The intuition not only influenced speed judgments but also judgments of distance traveled. Experiment 2 demonstrated that making sixth graders aware of the intuition and providing them kinesthetic experience that contradicted it produced significant improvements in the children's understanding. Implications for how scientific misconceptions in general can be overcome were discussed.     

Language,Experience and Professional Learning (What Walter Benjamin Can Teach Us)

This essay raises questions about how language educators might construct and further develop their epistemology of practice in and through the situations in which they work from day to day. The occasion for this paper is our work as guest editors of a special issue of L-1: Educational Studies in Language and Literature, when we invited L1 teachers to reflect on the role that language plays in their professional learning, whether it be in the form of conversations with peers, reflective writing, or by other means. We begin this essay by locating our reflections within our current policy context, namely the standards-based reforms that have come to dominate educational thinking around the world, offering a brief critique of the values and attitudes embedded within them. We then outline a philosophical framework as an alternative to the world-view reflected by such reforms, focusing specifically on the work of Walter Benjamin. In the final sections, we review our work as guest editors of the special issue of L-1, reflecting on what we have learned from the papers we have assembled for this issue, and locating our learning within the philosophical framework that we have drawn from Benjamin. We argue that it is timely for language educators to articulate the assumptions that inhere within their work, in contradistinction to the common sense embedded in standards. Thus we might begin to reconceptualise the relation between language, experience and professional learning in opposition to the hegemony of standards.     

Linking the shapes of alphabet letters to their sounds: the case of Hebrew

Learning the sounds of letters is an important part of learning a writing system. Most previous studies of this process have examined English, focusing on variations in the phonetic iconicity of letter names as a reason why some letter sounds (such as that of b, where the sound is at the beginning of the letter’s name) are easier to learn than others (such as that of w, where the sound is not in the name). The present study examined Hebrew, where variations in the phonetic iconicity of letter names are minimal. In a study of 391 Israeli children with a mean age of 5 years, 10 months, we used multilevel models to examine the factors that are associated with knowledge of letter sounds. One set of factors involved letter names: Children sometimes attributed to a letter a consonant–vowel sound consisting of the first phonemes of the letter’s name. A second set of factors involved contrast: Children had difficulty when there was relatively little contrast in shape between one letter and others. Frequency was also important, encompassing both child-specific effects, such as a benefit for the first letter of a child’s forename, and effects that held true across children, such as a benefit for the first letters of the alphabet. These factors reflect general properties of human learning.     

The ABC’s of Chinese: maternal mediation of Pinyin for Chinese children’s early literacy skills

In the present study, maternal Pinyin mediation and its relations with young Chinese children??s word reading and word writing development were explored. At time 1, 43 Mainland Chinese children and their mothers were videotaped on a task in which children were asked to write 12 words in Pinyin (a phonological coding system used in Mainland China as an aid to reading Chinese characters) with help from their mothers. The videotapes were later coded on a scale (adapted from Aram & Levin, 2001) of mothers?? writing facilitation techniques. Scores on this scale of maternal mediation of Pinyin uniquely explained children??s reading of Chinese words, but not writing of Chinese words, after statistically controlling for maternal education and age, and children??s non-verbal IQ, age, and phonological awareness. At time 2, 22 of the children from time 1 were further tested on Chinese word reading and word reading task 1?year later. After controlling for children??s age and non-verbal IQ, maternal Pinyin mediation uniquely explained 6% of the variance in children??s word writing and 7% of the variance in children??s word reading performance at time 2. Results underscore the potential importance of the maternal scaffolding role for reading acquisition both theoretically and practically in a domain not previously explored (i.e., use of a common coding system (Pinyin) for learning to read, rather than word reading itself).     

Effectively feeding forward from one written assessment task to the next

Most studies into lecturers’ written feedback focus on the types of feedback found to be effective when students have the opportunity to act on that feedback, revise their written assignment and improve the mark they receive. But often students do not have this opportunity. Typically, they receive a mark and feedback on an assignment that they will never be able to rework and resubmit. This can leave students unsure about what to do with the feedback they receive. This paper reports on the use of high impact written feedback from lecturers that significantly improved student outcomes and grades from one assessment task to the next. It examines a range of factors which together make feedback in this context effective including: assessment design, use of grading standards and tutor training. These findings from a very large unit have significant implications for teaching staff who want to use feedback to feed forward and make a real difference to their students’ learning.     

Demystifying the demand relationship between online and print products under one newspaper brand: the case of Taiwan and the emergence of a universal pattern

This study uncovers a universal pattern regarding the oft-misunderstood demand relationship between online and print products under one newspaper brand. Growing from the portfolio management perspective and building on previous research conducted in the US and Hong Kong, this study examines the newspaper market in Taiwan. Secondary analysis of survey data collected from 7706 Web users confirmed that: (1) the print edition attains a much higher penetration relative to its online counterpart, suggesting that more people would rather consume the print edition over free Web offerings; and (2) compared with the general public, readers of the online edition were more, not less, likely to read the same newspaper's print edition. Such counter-intuitive findings carry important theoretical and managerial implications regarding the management of multiple product offerings under one newspaper brand.     

Grade inflation under the threat of students’ nuisance: Theory and evidence

This study examines a channel, students’ nuisance, to explain grade inflation. “Students’ nuisance” is defined by “students’ pestering the professors for better grades.” This paper contains two parts: the game theoretic model and the empirical tests. The model shows that the potential threat of students’ nuisance can induce the professors to inflate grades. Ceteris paribus, a student is more likely to study little and to pester the professor for a better grade if: (1) the professor is lenient; (2) the studying cost is high; (3) the reward from pestering is high; (4) the cost of pestering is low.
