Accounting for individual variability in inversion shortcut use     

Adam K. Dubé  Katherine M. Robinson 《Learning and individual differences》2010,20(6):687-693

This study investigated whether children's inversion shortcut use (i.e., reasoning that no calculations are required for the problem 4 × 8 ÷ 8, as the answer is the first number) is related to their analogical reasoning ability, short-term memory capacity, and working memory capacity. Children from Grades 6 and 8 solved multiplication and division inversion problems and classical analogy word problems and completed memory tasks. Analogical reasoning ability and working memory functioning both accounted for individual variance in inversion shortcut use. These findings suggest that the ability to understand relationships and executive functioning may enable children to internally represent and manipulate mathematical problems, facilitating the application of conceptual mathematical knowledge to generate the inversion shortcut.  相似文献   

The role of negative priming in preschoolers' flexible rule use on the dimensional change card sort task     

Müller U  Dick AS  Gela K  Overton WF  Zelazo PD 《Child development》2006,77(2):395-412

Four experiments examined the development of negative priming (NP) in 3-5-year-old children using as a measure of children's executive function (EF) the dimensional change card sort (DCCS) task. In the NP version of the DCCS, the values of the sorting dimension that is relevant during the preswitch phase are removed during the postswitch phase. The experiments showed that the NP effect observed in the DCCS decreased during the preschool years, and they clarified the circumstances in which NP occurs. Taken together, the findings suggest that the development of EF in early childhood consists in part in disinhibiting attention to information that has previously been suppressed.  相似文献

Few studies have examined stability and change in attachment during adolescence. This 5‐year longitudinal study (a) examined whether prototype or revisionist developmental dynamics better characterized patterns of stability and change in adolescent attachment (at T1, N = 176; M_age = 14.0 years, SD = 0.9), (b) tested potential moderators of prototype‐like attachment stability, and (c) compared attachment stability in adolescence to stability in adulthood. The results supported the prototype model, which assumes that there is a stable, enduring factor underlying stability and change in attachment. Exploratory moderation analyses revealed that family conflict, parental separation or divorce, minority status, and male sex might undermine the prototype‐like stability of adolescent attachment. Stability of attachment was lower in adolescence relative to adulthood.  相似文献   

The Foodborne Outbreak Challenge—Using Experiential Learning to Foster Interdisciplinary Training Among Students on Foodborne Disease Outbreak Investigations          下载免费PDF全文

The Integrated Food Safety Centers of Excellence aim to develop novel learning methods to educate and train the future public health workforce to investigate foodborne outbreaks. The Foodborne Outbreak Challenge (FOC) was a one‐day event hosted by the Colorado Integrated Food Safety Center of Excellence at the Colorado School of Public Health. The FOC incorporated experiential, problem‐based, and interdisciplinary pedagogies from case studies, simulation exercises, and public health case competitions, to deliver a novel learning experience that met the training needs of a multidisciplinary foodborne outbreak response team with diverse skills sets. The event received positive feedback, and participants demonstrated knowledge gain. Event materials are available for other institutions to use.  相似文献   

Publisher–Society partnerships to further image accessibility and global inclusivity in the Humanities and Social Sciences: Comparing top-down and bottom-up approaches

• Collaboration between publishers and learned society partners can accelerate and amplify DEIA outcomes.
• 97 HSS titles have adopted alt-text publication workflows and this change has been welcomed by journal authors and editors.
• Efforts to promote global inclusivity do not always result in greater membership diversity, retention and growth.
• Top-down, publisher-led DEIA initiatives are effective when they are aligned strategically to pre-existing society initiatives.
• Bottom-up, member-led DEIA initiatives benefit from publisher support to mitigate financial and time-based barriers to active participation.
• To reliably track DEIA outcomes, publishers ought to adopt systematic data collection strategies through initiatives like C4 and the Joint Commitment.
