The Science Co-op is a local systemic change project that connects eight regional clusters of elementary schools in rural Missouri and Iowa in the USA. These clusters are comprised of 38 school districts distributed over 40,000 square miles and include more than 1,400 teachers and 20,000 elementary school students. The project stresses inquiry science in the classroom and involves investigating science ideas using a constructivist approach and cross-curricular connections. Within the frameworks of the Science Co-op project a technology known as Interactive Television (ITV) allows for almost real-time interaction (a 3–5 second delay) within the state boundaries of Missouri and Iowa, respectively. The primary goals of the ITV sessions are to enhance the science content and science pedagogical knowledge among the population of elementary school teachers that they may have lacked in their prior education, and to reinforce and extend instructional strategies emphasized in this local systemic change project. In this study the participants' self-reported learning and reactions to live ITV sessions and videotaped, delayed broadcast of ITV sessions were compared. Regression analysis results show teaching experience's influence on overall satisfaction with ITV (p<0.05) while mode attended, perceived technical difficulty, preferred mode, and perceived new skills or content learned in the session entered the regression equation at p=.000. Further t-tests suggested p>0.05 for perceived new skills and content learned on the different modes of communication. 相似文献

The experiences of middle school science teachers at two schools in the southeastern US who participated in collaborative,
sustained, whole-school professional development and their implementation of standards-based instructional practices are the
focus of this study. Participants were involved in their second year of the professional development experience. The research
question that was explored was “How are science teachers implementing standards-based instruction while participating in effective
professional development experiences?” Data collected in the form of teacher interviews and classroom observations using an
observation protocol. Findings indicate that even with effective professional development, teachers implement standards-based
instructional practices at varying levels. The reasons for these differences are discussed and the role of teacher beliefs
and the impact of beliefs, experience and support from administrators on professional development efforts are discussed. Implications
for future science education reform stakeholders and professional development efforts are revealed. 相似文献

The phrase “social movement” typically conjures up images of pickets, massive crowds, and noisy demonstrations. An emerging approach to campus‐based change, used in Fraternal Futures and other projects, is tapping into the small, the local, and the personally relevant. 相似文献

OBJECTIVE: To examine the relationship between parental history of substances use disorders (SUDs) and abuse potential. METHOD: Milner's (1986) Child Abuse Potential Inventory (CAPI) was administered to fathers and mothers (with and without histories of SUDs) of 10- to 12-year-old boys. RESULTS: Fathers and mothers with lifetime histories of SUDs had higher Abuse Scale scores and were more likely to score in the Elevated range (as determined by clinically significant cutoff scores) than parents without such histories. No differences were found between parents with current diagnoses of SUD and those with past (but not current) histories of SUD. Fathers and mothers with a partner who had a history of SUD were more likely to score in the Elevated range, regardless of their own SUD histories. Separate regression models revealed that, for both fathers and mothers, emotional dysregulation (positive and negative affectivity) predicted Abuse Scale scores. Additional contributors to Abuse Scale scores were SUD status in fathers, and lack of involvement with the child in mothers. CONCLUSIONS: History of SUDs in both fathers and mothers increases abuse potential. Contributors to abuse potential differed in fathers and mothers, underscoring the importance of examining parents separately in child maltreatment research. 相似文献
