Graphic symbols as "the mind on paper": links between children's interpretive theory of mind and symbol understanding

Children gradually develop interpretive theory of mind (iToM)—the understanding that different people may interpret identical events or stimuli differently. The present study tested whether more advanced iToM underlies children’s recognition that map symbols’ meanings must be communicated to others when symbols are iconic (resemble their referents). Children (6–9 years; N = 80) made maps using either iconic or abstract symbols. After accounting for age, intelligence, vocabulary, and memory, iToM predicted children’s success in communicating symbols’ meaning to a naïve map‐user when mapping tasks involved iconic (but not abstract) symbols. Findings suggest children’s growing appreciation of alternative representations and of the intentional assignment of meaning, and support the contention that ToM progresses beyond mastery of false belief.     

The connection between phonological,syntactic and semantic skills and children’s reading and spelling

In recent years two radically different views have dominated discussions about the way in which children learn to read and write. The first view is that the crucial hurdle in learning to read is the discovery of how to do the correct phonological analysis. The second view is that the crucial factor is the use of context, and that children use what they know about the meaning — and particularly the semantics and the syntax — of the passages that they are reading to help them decipher and learn about difficult written words. Learning to read is ‘a psycholinguistic guessing game’ according to this view and children set about it in much the same way as they set about learning to speak. Thus according to the first view children’s semantic and syntactic skills will determine their progress in reading and according to the second it will be their phonological skills. We present longitudinal evidence about a group of children in their first year at school which shows that both kinds of skill do play a part, but that they make entirely different contributions. Semantic and syntactic skills determine how well children make use of the context of what they are reading. Phonological skills affect their use of letter-sound relationships.     

Hierarchies in children's learning: A symposium

There has been a continuing increase in the application of hierarchy theory to the problems of instruction and evaluation, since Gagné first used the term hierarchy in his theory of how human beings acquire complex skills and knowledge. This article, based on a 1970 symposium of the American Educational Research Association, presents an overview and analysis of the use of learning hierarchies in instruction and research, examines some current research on learning hierarchies, and considers the implications of this research for instructional psychology and for theories of cognitive development.Lauren B.

Evaluation of patterning instruction for kindergartners

Abstract

To determine whether patterning instruction was as useful or more useful than other forms of instruction, kindergarten children (age five) were taught either patterning or early literacy or mathematics or social studies in matched sessions. Instruction was conducted in 15-minute sessions from November through mid-April. Posttests on patterning, mathematics, early literacy, and three executive functions showed that the children taught patterning became significantly better at patterning than those in the other instructional conditions. No differences were found between the children taught mathematics, early literacy, or social studies. Correlational analyses indicated that the relations of patterning ability, working memory, and inhibitory control to mathematics achievement were similar. Cognitive flexibility was not very strongly related to any other measure and the executive functions were relatively independent of each other for the children who were age five.     

The neighborhood walk: sources of support in middle childhood

This report documents children's perception of their involvement with self-development, family members, and members of the community and begins to test the relation between that network and aspects of social-emotional functioning during middle childhood. Support was conceptualized to include experiences of both relatedness to and autonomy from others. Three major types of reported support in this study using the Neighborhood Walk were considered: others as resources (e.g., persons in the peer, parent, and grandparent generation; pets), intrapersonal sources of support (e.g., hobbies; fantasies--structured and unstructured; skill development), and environmental sources of support (e.g., places to get off to by oneself; formally sponsored organizations with structured and unstructured activities; informal, unsponsored meeting places). One hundred sixty-eight children (72 7-year-olds and 96 10-year-olds), residing in nonmetropolitan and rural northern California and representing all but the lowest Hollingshead socioeconomic status, participated in this study. To assess their sources of support at home and in the neighborhood/community, each of these 168 children was taken on a Neighborhood Walk, and then several measures of social-emotional functioning were administered. Cross-sectional data form the empirical basis for a developmental perspective on sources of support, the structure of social-emotional functioning, and the relationship between sources of support and social-emotional functioning during middle childhood. The child's perception of support was found relevant to predicting the social-emotional functioning of children growing up in relatively secure and low-stress conditions in modern American society. Furthermore, a broad-based as opposed to a limited network and informal as opposed to formal sources of support were more predictive of social-emotional functioning. The empirical and theoretical relevance of considering middle childhood as a period of active development involving expansion and integration of social and affective phenomena was underscored by the results. First, it appears that the 7-year-olds have not yet developed the underlying response or habit clusters that characterize the 10-year-olds. Second, with respect to reported sources of support, 10-year-olds appear to have more elaborated sources of support than do 7-year-olds. Third, the findings confirm that developing a bridge to extended family and neighborhood resources is related to expressions of social-emotional functioning during middle childhood and that 10-year-olds appear to make effective use of more social support factors than do 7-year-olds.(ABSTRACT TRUNCATED AT 400 WORDS)     

“Why am I here?”: A phenomenological exploration of first-generation college student experiences in STEM majors within a predominantly white institution

First-generation college students (FGCSs) are a growing population in undergraduate education. Research on FGCS primarily focuses on the challenges and barriers they encounter in college. While important, this literature offers a limited view of FGCS as learners. Moreover, minimal literature has examined these students' lived experiences within sciences, technology, engineering, and mathematics (STEM). This study explores the learning experiences of FGCS (N = 17) in undergraduate STEM programs at a mid-sized, private, predominantly white institution. Guided by the frameworks of intersectionality and social cognitive career theory, the researchers utilized a qualitative, phenomenological research methodology to hear the perspectives of FGCS to and to identify problematic higher educational structures in STEM. Findings point to an elitist stance underlying STEM programs based in general disciplinary norms that restricted FGCS access to STEM majors and careers across social, academic, and professional elements of the academic experience. FGCS who were multiply minoritized based upon race, gender, and social class experienced the compounding of marginalization, and academic success and persistence came at a personal cost. Students also reported relying predominantly on personal strengths and motivations to overcome elitism in STEM rather than on institutional supports. Findings also highlight the variation in the first-generation experience and identify the unique barriers FGCS encounter within STEM fields. Implications for dismantling inequitable structures for higher education in STEM attending to the social, academic, and professional inclusion of FGCS.     

Demonstrating the positive impact of information support on patient care in primary care: a rapid literature review

AIM: To review the literature on the positive impact of information services, or information resources, on patient care in primary care. OBJECTIVES: To identify and summarize key papers on which librarians might draw in making the case for investment, and to highlight gaps in the research evidence Methodology: A rapid literature review was conducted in the summer of 2005. RESULTS: There is a small body of evidence to demonstrate the positive impact of library and information services on the direct care of patients as well as a beneficial impact on the care of future patients through the application of evidence to multiple patients. CONCLUSIONS: There is relatively limited research evidence of the impact of information, and library services, in primary care, in comparison with hospital settings and the research available is generally reliant on small samples. There is a lack of impact studies conducted with non-clinical staff. The review highlights the value of critical incident technique (CIT). It is possible to gather evidence of the potential for information services to deliver cost savings.     

Partial control and learned helplessness in rats: Control over shock intensity prevents interference with subsequent escape

The effect upon subsequent escape acquisition of control over shock intensity in the absence of control over other shock characteristics was examined. Pretreatment involved random shocks of 1.6 and .75 mA at a density of about 10/min. The experimental group could avoid the higher shock intensity if they leverpressed at least once every 15 sec. Yoked and no-shock rats completed the triadic design. Experimental and yoked animals received all scheduled shocks. Triads were later tested for FR 2 shuttlebox escape at either the .75 mA (low) or 1.6 mA (high) intensity. During testing, avoidance rats performed as well as no-shock rats at the low intensity and escaped even more rapidly at the high intensity. Yoked rats showed interference at both intensities, with interference very marked, including many failures to escape, at the low intensity. These findings indicate that control over shock intensity, by itself, is sufficient to prevent learned helplessness and suggest that control over any salient characteristic of shock may be sufficient for immunization.     

Characterizing disability in Head Start programs: Not so clearcut

Head Start programs are required to set aside at least 10% of program slots for children with disabilities, but the percentage of children with disabilities served varies depending on the criteria used and source of the information. This study used the Head Start Family and Child Experiences Survey (FACES) 2000 data for a nationally representative sample to identify subgroups of children meeting three different criteria for having a disability or developmental delay. Results indicated that about one-third of children in Head Start (33%) met one or more of the criteria for a disability or delay, about one-third of those children (33%) met criteria for two or for all three of the subgroups. However, only 8% of children in Head Start had an Individualized Education Program (IEP). Children with disabilities or delays, regardless of the subgroup criteria used, had higher levels of many other risk factors associated with poor developmental and school readiness outcomes. They also exhibited poorer performance on early literacy, social, and behavioral measures both at entry into Head Start and at the end of kindergarten compared with children not in each of those subgroups. Implications of the findings for screening and assessment, serving children in Head Start programs, and the need for linkages between Head Start programs and the preschool special education system are discussed.
