Selected AbstractsPracticing Change: Curriculum Adaptation and Teacher Narrative in the Context of Mathematics Education ReformCURRICULUM INQUIRY, Issue 2 2006COREY DRAKE ABSTRACT The use of reform-based curricula is one possible avenue for the widespread implementation of mathematics education reform. In this article, we present two urban elementary teachers' models of curriculum use that describe how each teacher used a reform-oriented mathematics curriculum. In particular, we examine when and how the teachers made adaptations to the curriculum. We find that each teacher had a distinctive pattern of adaptation when using the curriculum. Furthermore, these patterns were related to three key aspects of the teachers' own experiences with mathematics: their early memories of learning mathematics, their current perceptions of themselves as mathematics learners, and their mathematical interactions with family members. Implications for curriculum design and implementation are discussed.

He appeared to have some memories of the experience at 29 months of age, and he was able to superimpose verbal labels onto the preverbal memories. At 40 months of age, however, the memories were no longer verbally accessible. The results are discussed in the context of different theories of encoding, storage, retrieval, and loss of early memories. The findings from this study support other findings indicating that there appears to be some form of long-term memory in place early in life, at least for highly salient, traumatic events. There may be one memory system for traumatic memories, fully functional at birth, and a later developing, different system for neutral memories. It is further hypothesized that there may be a sensitive period around 2,3 years of age for the recall of early traumatic memories, and that verbal recall is more likely to be present in verbally precocious children during that period.

[source] Me Too!: Social modelling influences on early autobiographical memoriesAPPLIED COGNITIVE PSYCHOLOGY, Issue 2 2009Tiamoyo Peterson To investigate the malleability of early memories, 200 participants were asked to describe their earliest memories. Before doing so, approximately half were exposed to confederates who described very early memories such as their first steps or a second birthday party, while others were asked only to think about their earliest memories for two,minutes before beginning writing. Participants who were exposed to confederate very early memories produced memories that were nearly a year younger on average than the memories reported by controls (2.99 years vs. 3.96 years). Additionally, when participants in the memory discussion condition were asked about an early event that a confederate had recounted they were more confident than controls that they could recall the event in their own lives. These results indicate that autobiographical memories for early events are quite susceptible to social influence and that simply hearing the very early memories of others can alter autobiographical memory.

[source] Extracellular signal-regulated kinase activation is required for consolidation and reconsolidation of memory at an early stage of ontogenesisEUROPEAN JOURNAL OF NEUROSCIENCE, Issue 10 2009Solène Languille Abstract The ability to form long-term memories exists very early during ontogeny; however, the properties of early memory processes, brain structures involved and underlying cellular mechanisms are poorly defined. Here, we examine the role of extracellular signal-regulated kinase (ERK), a member of the mitogen-activated protein kinase/ERK signaling cascade, which is crucial for adult memory, in the consolidation and reconsolidation of an early memory using a conditioned taste aversion paradigm in 3-day-old rat pups. We show that intraperitoneal injection of SL327, the upstream mitogen-activated protein kinase kinase inhibitor, impairs both consolidation and reconsolidation of early memory, leaving short-term memory after acquisition and after reactivation intact. The amnesic effect of SL327 diminishes with increasing delays after acquisition and reactivation. Biochemical analyses revealed ERK hyperphosphorylation in the amygdala but not the hippocampus following acquisition, suggesting functional activation of the amygdala as early as post-natal day 3, although there was no clear evidence for amygdalar ERK activation after reactivation. These results indicate that, despite an immature brain, the basic properties of memory and at least some of the molecular mechanisms and brain structures implicated in aversion memory share a number of similarities with the adult and emerge very early during ontogeny.
