We investigated the inclusion of a curricular module on global climate change in an Elementary Science Methods course. Using complementary research methods, we analyzed findings from 63 teacher candidates’ drawings, questionnaires, and journal entries collected throughout their participation in the module. We highlighted three focal cases to illustrate the diversity of participants’ experiences. Findings suggest potential positive impacts on teacher candidates’ content understanding related to global climate change, confidence to teach, and awareness of resources to support their future science instruction. Recommendations for science teacher education underscore the importance of providing opportunities for teacher candidates to increase their relevant content understanding, helping teacher candidates become familiar with appropriate curricular resources, and engaging in ongoing conversation and evaluation of developing views and understandings related to global climate change.  相似文献

Negotiating White science in rural Black America: A case for navigating the landscape of teacher knowledge domains     

Randy Yerrick  Joseph Johnson 《Cultural Studies of Science Education》2011,6(4):915-939

The purpose of this study was to explore the nature of requisite teacher knowledge for teaching lower-track science students. Using video accounts, student focus groups, and teacher reflections researchers documented missteps, dead-ends, and unfruitful trajectories informed by the teacher’s incoming knowledge and compared these instances to necessary modifications informed by students’ voices and cultural artifacts. Our study revealed the shifting nature of sociocultural and pedagogical content knowledge of the teacher immersed in a context unlike that he experienced as a student. Results showed that teachers of majority backgrounds could learn to teach diverse students with at least moderate success from the perspective of their students. Implications for research and teacher education in diverse settings are discussed.  相似文献   

Parental Attitudes Regarding School-Based Sexuality Education in Utah     

Mindy Steadman  Benjamin Crookston  Randy Page 《American journal of sexuality education》2014,9(3):347-369

Sexuality education programs can be broadly categorized as either risk-avoidance or risk-reduction approaches. Health educators in Utah public schools must teach a state mandated risk-avoidance curriculum which prohibits the advocacy or encouragement of contraception. Multiple national surveys indicate that parents prefer a risk-reduction approach to sexuality education that promotes abstinence and the use of condoms or contraception for prevention of unwanted pregnancy and sexually transmitted infection. To date, no survey of Utah parents has been conducted.

This study utilized an Internet survey to gather data from 344 Utah parents to analyze their preferences regarding school-based sexuality education, sexuality topics, and support for objectives from the National Sexuality Education Standards. The vast majority of Utah parents surveyed support a risk-reduction approach to sexuality education, a wide variety of sexuality topics, and the majority of National Sexuality Education Standards. Statistically significant differences were identified by parents’ education, income, attendance at religious services, and political affiliation. Results support that Utah laws and education policies should be reexamined to provide for instruction that aligns with professional recommendations, best-practice recommendations based on peer-reviewed research, parental attitudes, and the needs of Utah teens.  相似文献   

SOURCES OF THE PUBLIC AGENDA:THE PRESIDENT-PRESS-PUBLIC RELATIONSHIP     

Miller  Randy E.; Wanta  Wayne 《Int. Journal of Public Opinion Research》1996,8(4):390-402

This agenda-setting study explores ways that individuals processinformation issues by examining two potential public agendasources: the news media and the president of the USA. The researchersused a two-site study to examine the magnitude of influencefrom media exposure and perceived credibility of source. Itwas found that the higher the level of exposure to media anda presidential state-of-the-union message, the more likely thatissues were considered important. However, when both were examinedsimultaneously, media exposure was the more powerful predictor.Source credibility, both of the media and the president, wasalso found to influence how people perceived the importanceof issues.  相似文献

Risk factors for infant maltreatment: a population-based study     

Wu SS  Ma CX  Carter RL  Ariet M  Feaver EA  Resnick MB  Roth J 《Child abuse & neglect》2004,28(12):1253-1264

CONTEXT: Of the approximately 900,000 children who were determined to be victims of abuse or neglect by US child protective services in 2002, the birth-to-3 age group had the highest rate of victimization (1.6%) and children younger than 1 accounted for the largest percentage of victims (9.6%). OBJECTIVE: To identify perinatal and sociodemographic risk factors associated with maltreatment of infants up to 1 year of age. DESIGN AND SETTING: Observational cohort study. PARTICIPANTS: 189,055 children born in 1996 in Florida. MAIN OUTCOME MEASURE: Infant maltreatment, defined as a verified report of abuse, neglect, or threatened harm that occurred between day 3 of life and 1 year. RESULTS: 1,602 children (.85%) of the 1996 birth cohort had verified instances of maltreatment by age 1. Of 15 perinatal and sociodemographic variables studied, 11 were found to be significantly related to infant maltreatment. Five factors had adjusted relative risks (RR) of two or greater: Mother smoked during pregnancy (RR 2.8); more than two siblings (RR 2.7); Medicaid beneficiary (RR 2.1); unmarried marital status (RR 2.0); low birth weight infant (RR 2.0). Infants who had four of these five risk factors had a maltreatment rate seven times higher than the population average. CONCLUSIONS: Data on nearly all risk factors found to be significantly associated with infant maltreatment are available on the birth certificate. Such information can be incorporated into a population-based risk-assessment tool that could identify subpopulations at highest risk for infant maltreatment. Because resources are limited, these groups should be given priority for enrollment in child abuse prevention programs.  相似文献
