Undergraduates entering science curricula differ greatly in individual starting points and learning needs. The fast pace, high enrollment, and high stakes of introductory science courses, however, limit students' opportunities to self-assess and modify learning strategies. The University of Washington's Biology Fellows Program (BFP) intervenes through a 20-session, premajors course that introduces students to the rigor expected of bioscience majors and assists their development as science learners. This study uses quantitative and qualitative approaches to assess whether the 2007-2009 BFP achieved its desired short- and long-term impacts on student learning. Adjusting for differences in students' high school grade point average and Scholastic Aptitude Test scores, we found that participation in the BFP was associated with higher grades in two subsequent gateway biology courses, across multiple quarters and instructors. Two to 4 yr after participating in the program, students attributed changes in how they approached learning science to BFP participation. They reported having learned to "think like a scientist" and to value active-learning strategies and learning communities. In addition, they reported having developed a sense of belonging in bioscience communities. The achievement of long-term impacts for a short-term instructional investment suggests a practical means to prepare diverse students for the rigors of science curricula.  相似文献   

Childrearing discipline and violence in developing countries     

Lansford JE  Deater-Deckard K 《Child development》2012,83(1):62-75

The present study examined the prevalence and country-level correlates of 11 responses to children's behavior, including nonviolent discipline, psychological aggression, and physical violence, as well as endorsement of the use of physical punishment, in 24 countries using data from 30,470 families with 2- to 4-year-old children that participated in UNICEF's Multiple Indicator Cluster Survey. The prevalence of each response varied widely across countries, as did the amount of variance accounted for by country in relation to each response. Country-level indicators of life expectancy, educational attainment, and economic well-being were related to several responses to children's behavior. Country-level factors are widely related to parents' methods of teaching children good behavior and responding to misbehavior.  相似文献   

Shared and distinctive origins and correlates of adult attachment representations: the developmental organization of romantic functioning     

Haydon KC  Collins WA  Salvatore JE  Simpson JA  Roisman GI 《Child development》2012,83(5):1689-1702

To test proposals regarding the hierarchical organization of adult attachment, this study examined developmental origins of generalized and romantic attachment representations and their concurrent associations with romantic functioning. Participants (N = 112) in a 35‐year prospective study completed the Adult Attachment Interview (AAI) and Current Relationship Interview (CRI). Two‐way analysis of variance tested interactive associations of AAI and CRI security with infant attachment, early parenting quality, preschool ego resiliency, adolescent friendship quality, and adult romantic functioning. Both representations were associated with earlier parenting and core attachment‐related romantic behavior, but romantic representations had distinctive links to ego resiliency and relationship‐specific romantic behaviors. Attachment representations were independent and did not interactively predict romantic functioning, suggesting that they confer somewhat distinctive benefits for romantic functioning.  相似文献   

Culture and child maltreatment: cultural competence and beyond     

Korbin JE 《Child abuse & neglect》2002,26(6-7):637-644

OBJECTIVE: The objective of this article is to comment on current issues in the relationship between culture and child maltreatment. METHOD: A review of the literature on culture and child maltreatment is the basis of the article. RESULTS AND CONCLUSION: While attention has been directed to the relationship between culture and maltreatment for more than 20 years, there is a need for further development in this area. Efforts need to be made to "unpack" culture, to promote understanding culture in context, and to enhance research on child maltreatment and culture.  相似文献

Maternal use of physical punishment in response to child misbehavior: implications for child abuse prevention     

Ateah CA  Durrant JE 《Child abuse & neglect》2005,29(2):169-185

OBJECTIVE: The objective was to examine the roles of cognition and affect in maternal use of physical punishment. METHOD: Through a review of the literature, distal and proximal predictors (cognitive and affective) of physical punishment use were identified. One hundred and ten mothers of 3-year-old children were interviewed regarding two disciplinary situations that occurred during the previous 2-week period that elicited their strongest reactions: one which resulted in the use of physical punishment (if this occurred) and one which did not. The individual and combined contributions of the predictors of physical punishment use were analyzed through logistic regression. RESULTS: The predictors of physical punishment following individual analyses were: maternal attitude toward physical punishment, maternal perception of the seriousness and intent of the child misbehavior, and maternal anger in response to the child misbehavior. Through multivariate analysis 54% of the variance in physical punishment use was explained. CONCLUSIONS: Both cognitive and affective factors affect the decision to use physical punishment with children. These findings can be useful in establishing parenting educational programming that is directed at decreasing the rates of physical punishment and subsequently child physical abuse.  相似文献   

Age and language skills of deaf children in relation to theory of mind development   总被引：2，自引：0，他引：2  

Lundy JE 《Journal of deaf studies and deaf education》2002,7(1):41-56

Using four traditional false-belief tasks, I investigated deaf children's age and expressive language skills in relation to their theory of mind development. The children's parents who signed reported on their own knowledge of a mental sign vocabulary. The results indicate age of the child to be strongly related to theory of mind development. Deaf children demonstrated an ability to pass the theory of mind assessment battery between the ages of 7 and 8 years, on average. In comparison, hearing children have consistently demonstrated the ability to perform such tasks between the ages of 4 and 5 years. Therefore, the results indicate deaf children are delayed by approximately 3 years in this cognitive developmental milestone. Expressive language skills of the children and sign language skills of the parents who signed were not found to be significantly related to the children's theory of mind development.  相似文献   

Extended visual fixation in the early preschool years: look duration, heart rate changes, and attentional inertia     

Richards JE  Cronise K 《Child development》2000,71(3):602-620

Visual fixation in infants from 6 months to 2 years of age was examined for its fit to the theory of "attentional inertia." A children's movie ("Sesame Street" movie, "Follow that Bird") or an extended audiovisual stimulus (computer-generated patterns) was presented to 40 children for a minimum of 20 min while fixation was videotaped and heart rate (HR) was recorded. Consistent with attentional inertia theory, fixations toward the stimuli had a lognormal distribution, HR decreased over the course of a look, and HR returned to prestimulus levels immediately before look offset. Older children (18 months, 24 months) showed a distinction in the parameters describing the lognormal distribution for the "Sesame Street" movie and the audiovisual patterns, whereas younger children (6 months, 12 months) responded similarly to the two stimulus types. Fixation patterns of children in this age range suggest attention increases over the course of a look, and parameters consistent with attentional inertia theory differentially develop in this age range.  相似文献   

Children "tune out" in response to the ambiguous communication style of powerless adults     

Bugental DB  Lyon JE  Lin EK  McGrath EP  Bimbela A 《Child development》1999,70(1):214-230

Changes in children's attentional engagement were assessed as a function of their exposure to "teachers" who differed in perceived power and the communication style that is associated with perceived power. In Study 1, "teachers" (women assigned to an instructional role) were selected on the basis of their perceived power; low-power women were more likely than high-power women to display communication ambiguity. Children responded to low-power women with low levels of (1) autonomic orienting (consistent with low attention) and (2) high errors on a cognitively demanding task (mental arithmetic). Attentional disengagement was found to be mediated by the ambiguous communication style of low-power adults. In Study 2, the "teacher" was a confederate who systematically varied the facial and vocal ambiguity of her instructions. Children showed the lowest levels of orienting and the highest level of errors when the "teacher" was ambiguous in both face and voice. Results were interpreted as showing that adult ambiguity (naturally occurring or experimentally produced) leads to reductions in children's attentional engagement.  相似文献   

Measurement properties of the MacArthur communicative development inventories at ages one and two years     

Feldman HM  Dollaghan CA  Campbell TF  Kurs-Lasky M  Janosky JE  Paradise JL 《Child development》2000,71(2):310-322

In a prospective study of child development in relation to early-life otitis media, we administered the MacArthur Communicative Development Inventories (CDI) to a large (N = 2,156), sociodemographically diverse sample of 1- and 2-year-old children. As a prerequisite for interpreting the CDI scores, we studied selected measurement properties of the inventories. Scores on the CDI/Words and Gestures (CDI-WG), designed for children 8 to 16 months old, and on the CDI/Words and Sentences (CDI-WS), designed for children 16 to 30 months old, increased significantly with months of age. On several scales of both CDI-WG and CDI-WS, standard deviations approximated or exceeded mean values, reflecting wide variability in results. Statistically significant differences in mean scores were found according to race, maternal education, and health insurance status as an indirect measure of income, but the directionality of differences was not consistent across inventories or across scales of the CDI-WS. Correlations between CDI-WG and CDI-WS ranged from .18 to .39. Our findings suggest that the CDI reflects the progress of language development within the age range 10 to 27 months. However, researchers and clinicians should exercise caution in using results of the CDI to identify individual children at risk for language deficits, to compare groups of children with different sociodemographic profiles, or to evaluate the effects of interventions.  相似文献
