Letter names and phonological awareness help children to learn letter-sound relations

Two experimental training studies with Portuguese-speaking preschoolers in Brazil were conducted to investigate whether children benefit from letter name knowledge and phonological awareness in learning letter-sound relations. In Experiment 1, two groups of children were compared. The experimental group was taught the names of letters whose sounds occur either at the beginning (e.g., the letter /be/) or in the middle (e.g., the letter /‘eli/) of the letter name. The control group was taught the shapes of the letters but not their names. Then both groups were taught the sounds of the letters. Results showed an advantage for the experimental group, but only for beginning-sound letters. Experiment 2 investigated whether training in phonological awareness could boost the learning of letter sounds, particularly middle-sound letters. In addition to learning the names of beginning- and middle-sound letters, children in the experimental group were taught to categorize words according to rhyme and alliteration, whereas controls were taught to categorize the same words semantically. All children were then taught the sounds of the letters. Results showed that children who were given phonological awareness training found it easier to learn letter sounds than controls. This was true for both types of letters, but especially for middle-sound letters.     

ROLES OF EPISTEMOLOGY IN INVESTIGATING KNOWLEDGE: “PHILOSOPHIZING WITH”

Abstract: This article aims at elucidating the ways in which philosophy may engage in cooperation with other disciplines through “philosophy with” ( Hansson 2008 ). An exemplary investigation is undertaken of the roles of epistemology in investigating knowledge, that is, how epistemology may interact with sciences concerned with knowledge. Four possible roles are distinguished: provider of a priori conceptual analyses, clarifier of scientific concepts and their implications, interpreter of scientific results, and dialogue partner with a voice of its own. Each role is illustrated by contemporary texts, and it is argued that the role of dialogue partner is the most fruitful.     

经验合作教学对教师课堂教学影响的实验研究

以"经验合作教学"的校本教师培训的新思路为依据,采用实验组、控制组前后测实验设计,选取初中语文和数学教师共33人,以年级学科组为单位施以为期8个月的经验合作教学干预,运用教育实验法考察经验合作教学对教师课堂教学(包括教学效能感、课堂情绪体验、教学效果)的影响。研究表明:(1)实验学校教师在一般教育效能感和教学效能感两个维度上的得分均较实验前有所提高,且个人教学效能感的提高量大于一般教育效能感;(2)实验学校教师轻松、愉快、满意的积极情绪体验的出现频率提高,失望的消极情绪出现频率降低;(3)实验学校教师在学生评价的课堂教学策略与互动、教学信息的总体把握与反馈两个维度的得分较实验前有所提高。     

Dissociation and association of the embodied representation of tool-use verbs and hand verbs: An fMRI study

Embodied semantic theories suppose that representation of word meaning and actual sensory-motor processing are implemented in overlapping systems. According to this view, association and dissociation of different word meaning should correspond to dissociation and association of the described sensory-motor processing. Previous studies demonstrate that although tool-use actions and hand actions have overlapping neural substrates, tool-use actions show greater activations in frontal–parietal–temporal regions that are responsible for motor control and tool knowledge processing. In the present study, we examined the association and the dissociation of the semantic representation of tool-use verbs and hand action verbs. Chinese verbs describing tool-use or hand actions without tools were included, and a passive reading task was employed. All verb conditions showed common activations in areas of left middle frontal gyrus, left inferior frontal gyrus (BA 44/45) and left inferior parietal lobule relative to rest, and all conditions showed significant effects in premotor areas within the mask of hand motion effects. Contrasts between tool-use verbs and hand verbs demonstrated that tool verbs elicited stronger activity in left superior parietal lobule, left middle frontal gyrus and left posterior middle temporal gyrus. Additionally, psychophysiological interaction analyses demonstrated that tool verbs indicated greater connectivity among these regions. These results suggest that the brain regions involved in tool-use action processing also play more important roles in tool-use verb processing and that similar systems may be responsible for word meaning representation and actual sensory-motor processing.     

Bringing forth spirituality dialogues in family therapy education

Our intention in the following article is to bring forth connections with spiritual resources in teaching and supervision. We construct this focus within a collaborative learning approach. Methods and techniques used include curiosity, reflexivity inquiry, deconstruction, outsider witness practices and re‐authoring conversations. We evaluate how the dialogue has transformed our abilities to relate to spirituality.     

Social Representations: A Normative and Dynamic Intergroup Approach

This commentary outlines an approach to social representations which emphasizes the normative and dynamic nature of shared knowledge. Social representations both connect and divide people, for example through shared ingroup and outgroup stereotypes derived from antagonistic social representations. Through asymmetrical intergroup communication and influence, in turn, social representations are formed, maintained, and contested. In this dynamic process, powerful majorities attempt to define the meaning of new or otherwise important information as a function of their group norms, while subordinate minorities employ propaganda techniques of social influence to resist majority influence and propose alternative positions.     

Parenting in relation to child and adolescent vocational development

Processes of child and adolescent vocational development include acquisition of knowledge, beliefs, and values about work options and requirements, exploration of interests that will be relevant for occupational interest development, development of academic aspirations, self-efficacy, expectations, and attainment. These elements serve to provide preparation for entry into a range of occupations and provide for the establishment of vocational aspirations, occupational self-efficacy, expectations, planning, and attainment. Parenting occurs within a family context influenced by a myriad of factors, including availability of financial capital, human capital, social capital, child agency, work-family interfacing, family roles, family structure, and the historical conditions affecting parents. These family contextual factors promote our understanding of differences in parenting in relation to child and adolescent vocational development. Far more complex than specific steps to entering the labor market per se, child and adolescent vocational development includes the interfacing of parenting and developmental processes.

Behavioral and self‐reported aggression as a function of domain‐specific self‐esteem

On the basis of a domain‐specific theory of self‐esteem, it was hypothesized that functionally distinct domains of self‐esteem would predict aggression differentially. Participants completed self‐report measures of self‐perceived superiority, mate value, social inclusion, and global self‐esteem, as well as of aggression. Self‐assessed mate value emerged as a reliable, positive predictor, and social inclusion as a reliable inverse predictor, of self‐reported hostility and aggression. In a subsequent laboratory experiment, in which participants had an opportunity to aggress against the source of positive or negative feedback about a personal essay that they had written, mate value again predicted increased aggression, whereas global self‐esteem predicted decreased aggression. These main effects were moderated by the feedback manipulation, such that their respective simple effects were only present among participants that received negative feedback. Aggr.

SHUTTING DRETSKE’S DOOR

Dretske proposes a theory of knowledge in terms of a theory of information, but wishes to deny that empirical knowledge settles the large question of scepticism. This leads him to deny the closure of knowledge under known entailment. In a recent paper J?ger argues that Dretske’s theory of information entails closure for knowledge, ‘at least for the kind of propositions here at issue’ (J?ger 2004:194). If J?ger is right, Dretske is seriously embarrassed and must give something up. In this paper I show that there are two flaws in J?ger’s argument. The principle of informational closure considered by J?ger is incompatible with Dretske’s theory of information, and J?ger’s argument that Dretske is committed to a certain kind of substitution instance of that principle of informational closure is invalid. I propose adequacy conditions on signalled information and use them to motivate a formulation of a general closure principle for signalled information. I show that Dretske’s account of information satisfies the adequacy conditions, but in a way which commits him to an instance of the general closure principle. I argue that Dretske is consequently committed to closure for some cases of knowledge for which he wishes to deny closure. Finally, I sketch how, on the basis of the closure principle to which Dretske is committed, J?ger’s broader argument may yet go through.
