In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. Wemay suggest strategies for dealingwith
them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences
and viewpoints on matters related to teaching and learning science. 相似文献

Economic well-being and children's social adjustment: the role of family process in an ethnically diverse low-income sample 总被引:1,自引:0,他引:1
Using latent variable structural equation modeling, a family economic stress model that links economic well-being to child well-being in an ethnically diverse, low-income sample of 419 elementary school-age children was evaluated. The sample was 57% African American and 28% Hispanic, and most families were headed by single mothers. The results provided support for the position that family process is a critical mediator of the effects of economic hardship on children's social adjustment. Lower levels of economic well-being, and the corollary elevated perceptions of economic pressure indirectly affected parenting behavior through an adverse impact on parental psychological well-being. Distressed parents reported feeling less effective and capable in disciplinary interactions with their child and were observed to be less affectionate in parent-child interactions. In turn, less than optimal parenting predicted lower teacher ratings of children's positive social behavior and higher ratings of behavior problems. Multiple-group analyses revealed that the pathways by which economic hardship influences children's behavior appear to operate similarly for boys and girls, and for African American and Hispanic families. 相似文献

Spatial visualization ability and laparoscopic skills in novice learners: Evaluating stereoscopic versus monoscopic visualizations 下载免费PDF全文
Victoria A. Roach Manisha R. Mistry Timothy D. Wilson 《Anatomical sciences education》2014,7(4):295-301
Elevated spatial visualization ability (Vz) is thought to influence surgical skill acquisition and performance. Current research suggests that stereo visualization technology and its association with skill performance may confer perceptual advantages. This is of particular interest in laparoscopic skill training, where stereo visualization may confer learning advantages to novices of variant Vz. This study explored laparoscopic skill performance scores in novices with variable spatial ability utilizing stereoscopic and traditional monoscopic visualization paradigms. Utilizing the McGill Inanimate System for Teaching and Evaluating Laparoscopic Skills (MISTELS) scoring protocol it was hypothesized that individuals with high spatial visualization ability (HVz) would achieve higher overall and individual MISTELS task scores as compared to low spatial visualization ability (LVz) counterparts. Further, we also hypothesized that a difference would exist between HVz and LVz individual scores based on the viewing modality employed. No significant difference was observed between HVz and LVz individuals for MISTELS tasks scores, overall or individually under both viewing modalities, despite higher average MISTELS scores for HVz individuals. The lack of difference between scores obtained under the stereo modality suggested that the additional depth that is conferred by the stereoscopic visualization may act to enhance performance for individuals with LVz, potentially equilibrating their performance with their HVz peers. Further experimentation is required to better ascertain the effects of stereo visualization in individuals of high and low Vz, though it appears stereoscopic visualizations could serve as a prosthetic to enhance skill performance.
