In this study, we sought to identify how feedback about classroom observations affected novice university mathematics instructors’ (UMIs) teaching practices. Specifically, we examined how a Red–Yellow–Green feedback system (RYG feedback) affected graduate student instructor (GSI) scores on an observation protocol (GSIOP). The protocol was developed specifically for this population, and both the GSIOP and RYG feedback were used within a peer mentoring program for GSIs, wherein novice GSIs were mentored by more experienced GSIs. Mentors observed novices’ classrooms using the GSIOP and provided RYG feedback as part of observation–feedback cycles. We analyzed 100 sets of scores, each collected over the course of a semester containing on average three observation–feedback cycles. Analyzing the semester-long datasets longitudinally provided insight into what types of feedback informed and influenced observed teaching. After qualitatively coding the feedback provided to the GSIs by their mentors along multiple dimensions, we found certain forms of feedback were more influential for observable changes in GSIs’ teaching. For example, pedagogical feedback that included contextualization (context and focal events) demonstrated a more positive change in GSIOP score than feedback that lacked contextualization. Our results suggest that contextual formative feedback has a positive change to student-focused and teacher-focused observations.

More research needs to examine how novice teachers successfully negotiate multiple ideologies with others in ways that allow them to construct preferred teaching identities. This qualitative study addressed that need by investigating how one high school English teacher negotiated contradictory ideologies related to writing instruction at her school. In particular, the study examined how the teacher negotiated ideologies with allies, students, and practitioner researchers. Implications suggested that practitioner research groups could provide support for ideological negotiations and teacher identity construction. Educators would benefit from teacher education that explicitly discusses and supports methods of negotiation through case study and video analysis.  相似文献

OBJECTIVE: To explore the relationships between psychological symptoms and thyroid hormone levels in adolescent girls who had experienced the traumatic stress of sexual abuse. METHOD: The study design was cross-sectional/correlational. Subjects (N=22; age range=12-18 years) had their blood drawn, and they completed 2 psychological tests (depression and general distress/posttraumatic stress disorder [PTSD]). A pediatrician completed a sexual abuse questionnaire after reviewing law enforcement and Child Protective Services reports and conducting forensic interviews and medical examinations. RESULTS: Girls' average free T4, total T4, free T3, total T3, and TSH levels were within age-specific laboratory reference range limits, as were most individual concentrations. The strongest correlations (p<.05) were between free T3 and PTSD total score (-.50), PTSD-avoidance/numbing (-.49), and general distress (-.48); and between total T3 and depression (-.46), general distress (-.45), and PTSD-arousal (-.44). CONCLUSIONS: Our findings support one of the two contemporary models of the relationships between thyroid hormones (i.e., free and total T3) and psychological symptoms (i.e., depression, general distress, and PTSD)--one of "shutting down" (vs. "activation") in the face of trauma.  相似文献

Spatial relations in American Sign Language (ASL) are often signed from the perspective of the signer and so involve a shift in perspective and mental rotation. This study examined developing knowledge of language used to refer to the spatial relations front, behind, left, right, towards, away, above, and below by children learning ASL and English. Because ASL is a classifier language in which noun referents are placed into groups, each spatial relation also appeared with person, animal, and vehicle classifiers. Twenty-three children and adults who learned ASL before the age of 5 years and 23 native English-speaking adults and children participated. Both language groups participated in a comprehension task in which they chose which of 2 pictures depicted a signed or spoken relation. Results showed that children learning ASL acquired the constructions for spatial relations that typically involve perspective shifts and mental rotation later than constructions that do not involve these abilities and later than English-speaking children. Children learning ASL did not differ from English-speaking children in learning constructions that did not involve these abilities. Results also suggest that users of ASL initially comprehend spatial relations more accurately with person and animal classifiers than with the classifier for vehicles. The results are relevant to understanding the acquisition of spatial relations in ASL.  相似文献

This study examined associations between parents' gendered attitudes about play and children's gender development. The sample was 501 families from a large US city followed annually for 4 years (501 mothers, 383 fathers; 69% White, 16% Latinx, 8% African American; children Mage = 5.67 months, 53% boys). Latent trajectories examined change in parents' attitudes toward same- and other-gender play during first 4 years of the child's life. On a subsample (n = 252), trajectories were examined in relation to children's later gender-typed preferences and gender constancy. Parents grew more gender-flexible in their attitudes, particularly parents of boys. Trajectories reflecting more stereotypic attitudes showed some associations (small in magnitude) with children's gender-typed preferences and gender constancy by age 4.  相似文献
