Within the field of formative research, there is debate as to whether researchers should collaborate with producers or serve as independent evaluators. The Children's Television Workshop (CTW) produces educational programs through a collaborative process of development that has come to be known as the “CTW Model”. Under the CTW Model, producers, content specialists, and researchers work together throughout the life of a project, from its initial conceptualization through its final production. This paper illustrates the value of the CTW Model via an in‐depth case study of the development and production of a single repeated format within Square One TV, an educational television series about mathematics. In particular, we focus on the multifaceted role played by formative research at all stages of production. 相似文献

This longitudinal study of 144 young adolescents (ages 9–11 at phase 1) examined the hypothesis that boys and girls would experience increased "gender-differential socialization" across a 1-year period in early adolescence, and that such patterns would be stronger in families in which ( a ) parents maintained a traditional division of labor, and ( b ) there was a younger sibling of the opposite gender. Longitudinal analyses of 3 aspects of family socialization (adolescents' participation in "feminine" and "masculine" household chores; adolescents' involvement in dyadic activities with mothers and fathers; parental monitoring) revealed that gender intensification was apparent for some aspects of family socialization but not others. In addition, when gender intensification was apparent, it generally emerged in some family contexts but not in others. Only dyadic parent-adolescent involvement was characterized by an overall pattern of gender intensification in which girls became increasingly involved with their mothers and boys with their fathers; this pattern was exacerbated in contexts where adolescents had a younger, opposite-sex sibling. 相似文献

The pattern of frontal activation as measured by the ongoing electroencephalogram (EEG) may be a marker for individual differences in infant and adult disposition to respond with either positive or negative affect. We studied 48 4-year-old children who were first observed in same-sex quartets during free-play sessions, while making speeches, and during a ticket-sorting task. Social and interactive behaviors were coded from these sessions. Each child was subsequently seen 2 weeks later when EEG was recorded while the child attended to a visual stimulus. The pattern of EEG activation computed from the session was significantly related to the child's behavior in the quartet session. Children who displayed social competence (high degree of social initiations and positive affect) exhibited greater relative left frontal activation, while children who displayed social withdrawal (isolated, onlooking, and unoccupied behavior) during the play session exhibited greater relative right frontal activation. Differences among children in frontal asymmetry were a function of power in the left frontal region. These EEG/behavior findings suggest that resting frontal asymmetry may be a marker for certain temperamental dispositions. 相似文献

This study explored verbal motivational strategies in exemplary teachers’ classrooms. A framework derived from expectancy-value theory, which addresses student motivation for academic tasks, was applied. Audiotaped math and literacy lessons of two exemplary second-grade teachers showed a high number of comments related to expectancies and relatively fewer related to valuing tasks. In addition, teachers made more motivational statements when in the process of instruction than when introducing or concluding instructional episodes. Interviews revealed that some teacher beliefs, such as the importance of rationales or ensuring student success, were related to classroom strategies. Implications for theory, practice, and research are discussed. 相似文献

It has been reasonably well established that test takers can, to varying degrees, answer some reading comprehension questions without reading the passages on which the questions are based, even for carefully constructed measures like the Scholastic Aptitude Test (SAT). The aim of this study was to determine what test-taking strategies examinees use, and which are related to test performance, when reading passages are not available. The research focused on reading comprehension questions similar to those that will be used in the revised SAT, to be introduced in 1994. The most often cited strategies involved choosing answers on the basis of consistency with other questions and reconstructing the main theme of a missing passage from all of the questions and answers in a set. These strategies were more likely to result in successful performance on individual test items than were any of many other possible (and less constructrelevant) strategies. 相似文献

OBJECTIVES: To assess the impact of home visiting in preventing child abuse and neglect in the first 3 years of life in families identified as at-risk of child abuse through population-based screening at the child's birth. METHODS: This experimental study focused on Hawaii Healthy Start Program (HSP) sites operated by three community-based agencies. From 11/94 to 12/95, 643 families were enrolled and randomly assigned to intervention and control groups. Child abuse and neglect were measured by observed and self-reported parenting behaviors, all hospitalizations for trauma and for conditions where hospitalization might have been avoided with adequate preventive care, maternal relinquishment of her role as primary caregiver, and substantiated CPS reports. Data were collected through annual maternal interviews (88% follow-up each year of all families with baseline interviews); observation of the home environment; and review of CPS, HSP, and pediatric medical records. RESULTS: HSP records rarely noted home visitor concern about possible abuse. The HSP and control groups were similar on most measures of maltreatment. HSP group mothers were less likely to use common corporal/verbal punishment (AOR=.59, p=.01) but this was attributable to one agency's reduction in threatening to spank the child. HSP group mothers reported less neglectful behavior (AOR=.72, .02), related to a trend toward decreased maternal preoccupation with problems and to improved access to medical care for intervention families at one agency. CONCLUSIONS: The program did not prevent child abuse or promote use of nonviolent discipline; it had a modest impact in preventing neglect. Possible targets for improved effectiveness include the program's implementation system and model. 相似文献

This study examined the effectiveness of a paired reading intervention using curriculum‐based measurement (CBM) probes to document reading progress for one fourth‐ and two third‐grade students. These students were considered below‐average readers. Parents and children used the paired reading method in their homes for 10 minutes, four times a week. Children and parents were also provided with reading material at their instructional level. Results showed that the children's reading accuracy and rates increased from baseline to follow‐up on CBM measures and on pre/posttesting. In addition, students and parents gave favorable treatment acceptability ratings for paired reading. Implications for future research are outlined. © 2003 Wiley Periodicals, Inc.

In the context of U.S. and world wide educational reforms that require teachers to understand and respond to student thinking about mathematics in new ways, ongoing learning from practice is a necessity. In this paper we report on this process for one teacher in one especially productive year of learning. This case study documents how Ms. Statz's engagement with children's thinking changed dramatically in a period of only a few months; observations and interviews several years later confirm she sustained this change. Our analysis focuses on the mathematical discussions she had with her students, and suggests this talk with children about their thinking in instruction served both as an index of change, and, in combination with other factors, as a mechanism for change. We identified four phases in Ms. Statz's growth toward practical inquiry, distinguished by her use of interactive talk with children. Motivating the evolution of phases were two sorts of mechanisms: scaffolded examination of her students' thinking; and asking and answering questions about individual students' thinking. Processes for generating and testing knowledge about children's thinking ultimately became integrated into Ms. Statz's instructional practices as she created opportunities for herself, and then students, to hear and respond to children's thinking. 相似文献

92 7–9-year-old children (47 girls) were observed while attempting to join 2 relatively unfamiliar same- or opposite-sex peers who were playing a board game. Female guests were less obtrusive than male guests in their entry approaches, whereas male guests were more active and assertive. Guests were less behaviorally constrained when approaching same- than opposite-sex hosts. Female hosts were more attentive to the guests than male hosts, who tended to ignore the newcomers. Successful guests received initiations from the hosts, responded contingently to host initiations, and performed activity-related behavior. Since female hosts initiated more behavior to the guests than male hosts, and female guests were more contingently responsive than male guests, girls entering female groups were the most successful. These findings support the thesis that peer group entry processes and outcomes are affected by the personal characteristics and contexts of both the entering children and their hosts. 相似文献
