The current study compared monitoring in time- and event-based prospective memory (PM). Time- and event-based non-focal task instructions were given after a baseline block of a lexical decision ongoing task. Delay between instruction and presentation of PM cue/time was manipulated between-subjects to examine monitoring across short delays (1–6?min). Longer delays decreased performance in the event-based task, but not in the time-based task. This accuracy decline was accompanied by a decline in monitoring (as measured by PM cost to the ongoing task in the trials immediately before the PM cue was presented) between the 1 and 3?min delays. Monitoring was only evident for the time-based task at the 6?min delay as measured by PM cost to the ongoing task. Clock checks were also not affected by delay, but did increase in frequency as the response time neared. These results suggest that delay from the time of intention formation decreases both accuracy and monitoring in event-based tasks, but does not decrease accuracy or monitoring in time-based tasks.  相似文献

Learning progressions have been demarcated by some for science education, or only concerned with levels of sophistication in student thinking as determined by logical analyses of the discipline. We take the stance that learning progressions can be leveraged in mathematics education as a form of curriculum research that advances a linked understanding of students learning over time through careful articulation of a curricular framework and progression, instructional sequence, assessments, and levels of sophistication in student learning. Under this broadened conceptualization, we advance a methodology for developing and validating learning progressions, and advance several design considerations that can guide research concerned with engendering forms of mathematics learning, and curricular and instructional support for that learning. We advance a two-phase methodology of (a) research and development, and (b) testing and revision. Each phase involves iterative cycles of design and experimentation with the aim of developing a validated learning progression. In particular, we gathered empirical data to revise our hypothesized curricular framework and progression and to measure change in students. thinking over time as a means to validate both the effectiveness of our instructional sequence and of the assessments designed to capture learning. We use the context of early algebra to exemplify our approach to learning progressions in mathematics education with a focus on the concept of mathematical equivalence across Grades 3-5. The domain of work on research on learning over time is evolving; our work contributes a broadened role for learning progressions work in mathematics education research and practice.  相似文献

Community psychology is central to understanding how immigrants and more established residents of their new settings join together to develop a shared sense of community and membership. In our present study, we explored how newer (i.e., first‐ and second‐generation immigrants) and more established community members form multiple positive psychological sense of community (PSOC) with one another. We conducted a multinational, qualitative study of PSOC through interviews with 201 first‐ and second‐generation immigrants and third generation or more “receiving community members” in three contexts (Baltimore‐Washington corridor of the U.S.; Torino, Italy; Lecce, Italy). Results indicated numerous similarities among the ways in which participants constructed PSOC in shared and nonshared communities, regardless of immigration/citizenship status, length of community residence, city, country, age, or gender. Small, proximal, and salient communities were often particularly important to building positive PSOC, which was formed around diverse membership boundaries. As intersectional beings, members converged and diverged on many characteristics, providing multiple opportunities for members to bring diversity to their communities while sharing other characteristics deemed essential to membership. Nonetheless, findings point to significant, structural challenges rooted in power and privilege that must be confronted to bridge the community‐diversity dialectic and build strong, shared sense of community.  相似文献

Abstract

This paper presents a case study of a first grade student to illustrate the diversity of her understandings related to variables and variable notation. While prior research has documented secondary school students’ difficulties with variables and variable notation, we identify many productive understandings in this much younger student, leading us to question the prevailing argument that students might have difficulties with variables due mostly to their own limitations. We draw our data from a teaching experiment that explored functional relationships. Individual interviews were carried out with a subset of the students in the experiment prior to, as well as mid-way through and at the end of the experiment. This paper focuses on a set of three interviews with one of the first grade students. We illustrate the shifts that occurred in the student’s understandings about variables and variable notation across as well as within each of the three interviews.  相似文献

In recent international and Australian early childhood curriculum guidelines and child-protection policies, the need for teachers of young children to foster spirituality has been highlighted. However, what this might mean in practice has not been widely explored. This article addresses the more controversial issue of spiritual abuse and the right of children to protection in terms of spiritual development. We present a critique of current definitions taken from research and policy documents. Qualitative data provide the research background. Vignettes are presented to give examples of what spiritual harm might look like in practice. Finally, a strengths-based approach is introduced and strategies are suggested in order to explore the potential of the Strengths Approach (a social justice approach originating from social service practice) to aid early years’ teachers to create spiritually protective learning environments. This approach recognises and values children’s holistic development and wellbeing and supports them to appreciate, engage with and question the world around them with a resilient spirit.  相似文献

A new grouping principle, uniform connectedness (UC), has been posited to be a basic organizer of visual pattern information, one that takes precedence over other, more classic grouping principles (Palmer & Rock, 1994), but its ontogenetic origins have not previously been investigated. We examined whether 3- to 4-month-olds and 6- to 7-month-olds utilize UC to organize static two-dimensional displays. Infants habituated to uniformly connected patterns exhibited a novelty preference for disconnected element patterns, whereas those without any habituation failed to exhibit a preference. The results indicate that infants are sensitive to UC as a cue for perceptual organization. Prior studies indicate that some Gestalt principles (e.g., common movement) are functional during the first half year of life, but that other principles (e.g., form similarity) are less readily available. The present finding showing that young infants are sensitive to UC points to the foundational nature of this cue and adds to an emerging body of evidence indicating that at least some of the mechanisms believed to produce perceptual organization in adults are already operational in the first months of life. nt]mis|This research was supported by grants from the National Science Foundation (BCS 0224240) and the National Institute of Child Health and Human Development (HD042451).  相似文献
