Management and organization in science classrooms

Twenty-six junior high and middle school science classes taught by 13 teachers were observed frequently during the first 2 months of school and during 2 months in the middle of the year to identify classroom management and instructional organization variables related to high levels of student task engagement and low levels of off task and disruptive behavior. Sub-samples of more and less effective managers were identified, and narrative data from their classes were analyzed to describe and illustrate effective strategies for managing science classroom activities.     

Timmy’s in the well: Empathy and prosocial helping in dogs

Dogs are thought to evaluate humans’ emotional states, and attend more to crying people than to humming people. However, it is unclear whether dogs would go beyond focusing attention on humans in need by providing more substantive help to them. This study used a trapped-other paradigm, modified from use in research on rats, to study prosocial helping in dogs. A human trapped behind a door either cried or hummed, and the dog’s behavioral and physiological responses (i.e., door opening and heart rate variability) were recorded. Then, dogs participated in an impossible task to evaluate gaze at the owner as a measure of the strength of their relationship with their owner. Dogs in the distress condition opened at the same frequency, but significantly more quickly, than dogs in the control condition. In the distress condition, the dogs that opened showed lower levels of stress and were able to suppress their own distress response, thus enabling them to open the door more quickly. In the control condition, opening was not related to the dog’s stress level and may have instead been motivated by curiosity or a desire for social contact. Results from the impossible task suggest that openers in the distress condition may have a stronger bond with their owner than non-openers, while non-openers in the control condition showed a stronger bond than openers, which may further suggest that the trapped-other paradigm is reflective of empathy.     

Patterns of Competence and Adjustment among Adolescents from Authoritative, Authoritarian, Indulgent, and Neglectful Families

In order to test Maccoby and Martin's revision of Baumrind's conceptual framework, the families of approximately 4,100 14-18-year-olds were classified into 1 of 4 groups (authoritative, authoritarian, indulgent, or neglectful) on the basis of the adolescents' ratings of their parents on 2 dimensions: acceptance/involvement and strictness/supervision. The youngsters were then contrasted along 4 sets of outcomes: psychosocial development, school achievement, internalized distress, and problem behavior. Results indicate that adolescents who characterize their parents as authoritative score highest on measures of psychosocial competence and lowest on measures of psychological and behavioral dysfunction; the reverse is true for adolescents who describe their parents as neglectful. Adolescents whose parents are characterized as authoritarian score reasonably well on measures indexing obedience and conformity to the standards of adults but have relatively poorer self-conceptions than other youngsters. In contrast, adolescents from indulgent homes evidence a strong sense of self-confidence but report a higher frequency of substance abuse and school misconduct and are less engaged in school. The results provide support for Maccoby and Martin's framework and indicate the need to distinguish between two types of "permissive" families: those that are indulgent and those that are neglectful.     

The influence of model infant—toddler group care on parent-child interaction at home

The effects of day care participation on parent-child interaction at home were assessed using a university-based, half-day model infant—toddler program. Hypotheses concerned whether “child-centered” features of the physical and social environment were carried over by parents to the home. Nineteen matched pairs of center and noncenter children (ages 2 to 24 months at start) were followed for 8 months. All had employed student mothers. Methods included brief parent-reported “spot” observations, a videotaped observation of a bathing or feeding routine, and home environment assessments. Parents showed few group differences during the first half of the study period. At study end, however, center homes were more child-centered with respect to play, safety, and dinner arrangements. Center parents scored higher in proximity and warmth and lower in “teacher-avoided” behaviors. Noncenter parents at study end scored higher in authority (limit setting) and communicating values and labels. The findings are interpreted as supporting an ecological model of substantial intersection and cross-influence between home and day care settings.
