Mother and toddler activity in the zone of proximal development for pretend play as a predictor of higher child IQ

This study investigated the pretend play of mother—toddler dyads in relation to later child IQ. Twenty-one toddlers were videotaped in monthly play sessions with their mothers, from age 8 to 17 months, and later assessed at 5 years of age on the Stanford-Binet IV. Children's and mothers' pretend play levels and frequencies were measured using Brown's (1997) Pretend Play Observation Scale. Dyadic play activity was analyzed using the conceptual frameworks of scaffolding and Vygotsky's Zone of Proximal Development (ZPD). Toddlers later assessed as having higher IQ demonstrated more rapid learning in the ZPD for pretend play and experienced earlier maternal transfer of responsibility for play. These findings support other evidence on the differential early development of high ability or gifted children and the role of caregiver interactions in that development.

Putting the Research to Use: This study provides evidence that gifted children show differential development, in this case more rapid learning, from the first year of life. It also demonstrates how responsive parental interactions can support this advanced development. For family and professional caregivers, the findings imply that optimum caregiving for the young gifted child involves interactions that are both responsive to individual potential and appropriately challenging. In regard to the methodological challenges of researching early giftedness, the study demonstrated that the constructs of the ZPD and scaffolding were useful frameworks for investigating early gifted development and caregiver influences on that development. Pretend play activity was also shown to be an effective measure and a useful context for the study of gifted development in infants and toddlers. It would be valuable for future researchers in this area to utilize similar approaches that are grounded in the unique developmental characteristics of young children, and that aim to account for the interactive contexts that are so important in children's lives. The field of gifted education, in general, would also benefit from an increased awareness and exploration of the role of play in the development of intellect, imagination and creativity.

Towards a cultural historical theory of knowledge mapping: collaboration and activity in the zone of proximal development

This chapter locates knowledge mapping within the theoretical framework of cultural historical activity theory. Cultural historical activity theory provides an analytic tool for understanding how knowledge maps can act as “stimuli-means”: a cultural artefact that can mediate the performance of subjects (Vygotsky, 1978 ). Knowledge maps possess Vygotsky’s double nature: they not only enable students to enact academic practice but also allow refl ection on that practice. They enable students to build an “internal cognitive schematisation of that practice” (Guile, 2005 , p.127). Further, cultural historical activity theory gives the tools to analyse the social context of our use of knowledge maps and thus consider the mediating rules (tacit and explicit) and division of labour that mediate our use of knowledge maps. Knowledge maps can be viewed as acting within Brandom’s ( 2000 ) space of reasons , which allows learners to use reasons to develop and exchange judgements based on shareable, theoretically articulated concepts and collectively develop the ability to restructure their knowledge and enact these judgements (Guile, 2011 ). In particular multimodal collaborative knowledge maps can act as Vygotsky’s (Vygotsky, 1978 ) zone of proximal development , where teacher and peer-to-peer interaction allow students to solve problems and learn concepts and skills that they would be otherwise unable to tackle.

Adolescencia y escuelas: Interpelando a Vygotsky en el siglo XXI : Unidades de análisis que entrelazan tramas y recorridos, encuentros y desencuentro

El objetivo es presentar categorías construidas por Vigotsky desde un enfoque psicológico y educativo, para enriquecer perspectivas sobre relaciones entre adolescentes y escuelas, integrando el contexto social e histórico en el que se inscriben. Se problematiza la concepción de fracaso escolar y de educabilidad de los sujetos, que los reduce a problemas individuales. Los textos de Vigotsky en Paidología del adolescente , escritos hace casi ochenta años, anticipan y proveen insumos significativos para la agenda de problemas contemporáneos sobre el desarrollo de los sujetos y las prácticas educativas. Se enfocan las unidades de análisis en el estudio de fenómenos psicoeducativos, para explicar y comprender conductas, funciones y procesos, desde planos personales, interpersonales y socioculturales. El recorrido del autor, pionero del enfoque socio-histórico-cultural, abarca dimensiones complejas, como intereses, pensamiento conceptual, imaginación y personalidad, analizando los procesos psíquicos superiores como desarrollos de la historia cultural de los adolescentes. Se articula el análisis de la obra con la revisión que autores contemporáneos post-vigotskianos realizan de la categoría de Zona de Desarrollo Próximo. La lectura puede ampliar la perspectiva de agentes psicoeducativos sobre problemas y estrategias de intervención, tomando distancia de una lógica aplicacionista y enriqueciendo las lógicas de implicación y transformación situacional

The potential for utilising the collaborative learning spaces approach in the delivery of résumé development education

This study investigated the potential for using collaborative learning spaces for the development of résumé writing knowledge and skills in higher education students. Utilising a collaborative learning environment, 227 students from a mix of programmes and year levels participated in one of 24 workshops centering on a technology supported, shared review and reflection approach to résumé construction. It was concluded that use of technology supported collaborative learning spaces has the potential to be a valuable, innovative approach for the delivery of career management related skills in higher education.

Cytokinin signalling in the regulation of cambial development

Secondary growth of plants is of pivotal importance in terrestrial ecosystems, providing a significant carbon sink in the form of wood. As plant biomass accumulation results largely from the cambial growth, it is surprising that quite little is known about the hormonal or genetic control of this important process in any plant species. The central aim of my thesis studies was to explore the function of cytokinin in the regulation of cambial development. Since their discovery as regulators of plant cell divisions, cytokinins have been assumed to participate in the control of cambial development. Evidence for this action was deduced from hormone treatment experiments, where exogenously applied cytokinin was shown to enhance cambial cell divisions in diverse plant organs and species. In my thesis work, the conservation of cytokinin signalling and homeostasis genes between a herbaceous plant, Arabidopsis, and a hardwood tree species, Populus trichocarpa. Presumably reflecting the ancient origin of cytokinin signalling system, the Populus genome contains orthologs for all Arabidopsis cytokinin signalling and homeostasis genes. Thus, genes belonging to five main families of isopentenyl transferases (IPTs), cytokinin oxidases (CKXs), two-component receptors, histidine containing phosphotransmitters (HPts) and response regulators (RRs) were identified from the Populus genome. Three subfamilies associated with cytokinin signal transduction, the CKI1-like family of two-component receptors, the AHP4-like HPts, and the ARR22-like atypical RRs, were significantly larger in Populus genome than in Arabidopsis. Potential contribution to the extensive secondary development of Populus by the members of these considerably expanded gene families will be discussed. Representatives of all cytokinin signal transduction elements were expressed in the Populus cambial zone, and most of the expressed genes appeared to be slightly more abundant on the phloem side of the meristem. The abundance of cytokinin related genes in the cambium emphasizes the important role of this hormone in the regulation of the extensive secondary growth characteristic of tree species. The function of the pseudo HPts in primary vascular development was studied in Arabidopsis root vasculature. It was demonstrated that the pseudo HPt AHP6 has a role in locally inhibiting cytokinin signalling in the protoxylem position in the Arabidopsis root, thus enabling differentiation of the protoxylem cell file. The possible role of pseudo HPts in cambial development will be discussed. The expression peak of cytokinin signalling genes in the tree cambial zone strongly indicates that cytokinin has a role in the regulation of this meristem function. To address whether cytokinin signalling is required for cambial activity, transgenic Populus trees with modified cytokinin signalling were produced. These trees were expressing a cytokinin catabolic gene from Arabidopsis, CYTOKININ OXIDASE 2, (AtCKX2) under the promoter of a Betula CYTOKININ RECEPTOR 1 (BpCRE1). The pBpCRE1::CKX2 transgenic Populus trees showed a reduced concentration of a biologically active cytokinin, correlating with their impaired cytokinin response. Furthermore, the radial growth of these trees was compromised, as illustrated by a smaller stem diameter than in wild-type trees of the same height. Moreover, the level of cambial cytokinin signalling was down-regulated in these thin-stemmed trees. The reduced signalling correlated with a decreased number of meristematic cambial cells, implicating cytokinin activity as a direct regulator of cambial cell division activity. Together, the results of my study indicate that cytokinins are major hormonal regulators required for cambial development.
