Early Childhood Educare: Seeking a theoretical framework in Vygotsky's work

This paper argues that there is no meaningful distinction between care and education for young children so that the early childhood field should be renamed early childhood educare. The predominant theoretical framework for early childhood philosophy and curriculum has been Piaget's theory. Piaget's theory describes development as determining current cognitive competence and influencing what children are capable of learning. Children are seen as natural scientists who investigate the world and thereby broaden their understanding. Teachers are expected to stand back and provide resources for children's autonomous learning but not to interfere with it. The paper argues that Vygotsky's theory as applied to the responsive social contexts provided in early childhood educare should be given more consideration because it gives more attention to the importance of the social and cultural context on children's thinking than Piaget. Vygotsky saw learning as driving development and the development of thinking as a shared process rather than an individual one. Children are capable of far more competent performance when they have assistance from adults in their zone of proximal development so adults take a reactive and participatory role. The paper discusses the role of language, the internalisation of interpersonal processes, the importance of intersubjectivity, the need for scaffolding in the zone of proximal development, and the role of both adult and peer tutors according to the author's interpretation of Vygotsky's theory.     

Maternal and Child Characteristics that Influence the Growth of Daily Living Skills from Infancy to School Age in Preterm and Term Children

Research findings. Growth across 6 months to 8 years of age, assessed at seven time points, for daily living and cognitive skills was compared for term (n = 122), very low birth weight (VLBW) children of low (n = 114) and high (n = 73) medical risk and lower socioeconomic status (SES). Dramatic declines in daily living skills were found for all children, while cognitive skills were stable across this age range. By 8 years, daily living skills were in deficient ranges for all groups with both VLBW groups showing lower levels in both skill areas across all ages compared to term children. Relations between child and parenting factors and daily living skill growth were examined in order to better understand this decline. Early maternal general stimulation and directiveness predicted slower declines in daily living skills while higher parental developmental expectations predicted higher levels in daily living skills. Practice. These results demonstrated the negative impact of lower SES and biological risk on children's growth in daily living skill. The findings highlighting several parenting factors that are important in understanding individual differences in children's daily living skill development have implications for early intervention.     

Using a computerized concept mapping program to assess preservice teachers' thinking about effective teaching

Concept mapping with Learning Tool, a computerized mapping program, was used to assess changes in the content and organization of 17 preservice teachers' concept maps for the topic of effective teaching. Preservice teachers in their senior year of an early childhood teacher education program constructed and revised concept maps with a partner. They entered reflections on each mapping experience into their reflective journals, developing implications for teaching. Analysis of the concept maps revealed that these students had a primary concern with classroom management throughout the year, linking diverse information to that concept. They evidenced detailed and diverse understandings under the labels of knowledge and organization. Professionalism was a common item, though it was less well developed. Their reflective journals indicated that these students moved from describing emotional reactions to using the computer program as a basis for reflection on the teaching/learning process. This study illustrates how concept mapping can be useful in describing students' evolving constructions of knowledge in a particular subject area, and in promoting reflection.     

ASSESSING TERTIARY STUDENTS IN AN EDUCATION FACULTY: RHETORIC AND REALITY

This paper focuses on the reported use of literature‐based essays (i.e., essays that draw upon established literature in their construction) in assessing students within an Education Faculty in an Australian University. Interviews with academic staff and with students were used to explore how literature‐based essays were used in the context of the assessment program for the unit (subject) and how such assessment tasks were viewed by academic staff and their students. The reported use of literature‐based essays is evaluated in terms of three criteria for sound assessment derived from the literature and the perceptions of academic staff and their students are compared in relation to each criterion. It is concluded that a number of the academic staff within the Education Faculty displayed significant shortcomings in their theoretical knowledge of assessment and that their use of literature‐based assessments frequently failed to meet one or more of the requirements for an adequate assessment program at tertiary levels.     

Contraceptive and sexuality knowledge among inner-city middle school students from minority groups

In exchange for a free physical examination, 116 minority group youths from inner-city middle schools in Texas consented to answer open-ended questions about their sexual behavior, contraceptive knowledge, and type and source of knowledge of sexuality. The students ranged in age from 12-15 years (mean age, 13 years); 27% were Hispanic and 73% were black. Sex education was not a part of the curriculum at the 4 schools from which respondents were drawn. When asked what sex meant to them, 37% of female adolescents and 23% of males indicated they did not know or it did not mean anything. Among remaining students, recreation was identified as the central meaning be males (23% of total), while females tended to cite romance (21% of total). Only 47% were able to list at least 1 question they had about sex; most common were questions about the morality of premarital intercourse and the experience of adolescent pregnancy and parenthood. 89% of females and 57% of males were able to name at least 1 contraceptive method, generally condoms (44%), abstinence (36%), and the pill (8%). Hispanic females named the highest number of contraceptive methods on average (2.2), followed by black females (1.9), Hispanic males (1.8), and black males (1.3). Among female adolescents, 53% listed their mother as their primary source of knowledge about sexual matters and 6% listed a friend. Among males, fathers (17%) and friends (17%) were the most frequent knowledge sources. The fact that these young adolescents view their parents as credible and approachable sources of information about sexuality suggests that school counselors should encourage such communication. aT the same time, the expressed need for more information on the moral aspects of sexuality indicates that values should be incorporated into any sex education program developed for this age group.     

New evidence on the development of the word big

Previous studies of children's understanding of big suggest a curvilinear trend. 3-year-olds, like adults, interpret big as referring to area, while 5-year-olds take big to mean tall. The results of 6 experiments indicate that the curvilinear trend is not obtained in all stimulus contexts. When objects vary extremely, younger and older children take big to mean tall. The object to which big is applied also influences whether height, length, or area is attended to. Moreover, in a production task, adults rarely used the work big to describe the stimuli with which children's understanding of big is typically tested. Taken together, the results suggest that the meaning and use of big is complex and that big may not at any age refer simply to the larger object. It is proposed that the meaning of big is a dynamic system driven by a multiple of perceptual, conceptual, and semantic influences.     

A comparison of feature selection methods for an evolving RSS feed corpus

Previous researchers have attempted to detect significant topics in news stories and blogs through the use of word frequency-based methods applied to RSS feeds. In this paper, the three statistical feature selection methods: χ², Mutual Information (MI) and Information Gain (I) are proposed as alternative approaches for ranking term significance in an evolving RSS feed corpus. The extent to which the three methods agree with each other on determining the degree of the significance of a term on a certain date is investigated as well as the assumption that larger values tend to indicate more significant terms. An experimental evaluation was carried out with 39 different levels of data reduction to evaluate the three methods for differing degrees of significance. The three methods showed a significant degree of disagreement for a number of terms assigned an extremely large value. Hence, the assumption that the larger a value, the higher the degree of the significance of a term should be treated cautiously. Moreover, MI and I show significant disagreement. This suggests that MI is different in the way it ranks significant terms, as MI does not take the absence of a term into account, although I does. I, however, has a higher degree of term reduction than MI and χ². This can result in loosing some significant terms. In summary, χ² seems to be the best method to determine term significance for RSS feeds, as χ² identifies both types of significant behavior. The χ² method, however, is far from perfect as an extremely high value can be assigned to relatively insignificant terms.
