The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development “best practices” and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course. 相似文献

Objective
The research obtained information to plan data-related products and services.Methods
Biomedical researchers in an academic medical center were selected using purposive sampling and interviewed using open-ended questions based on a literature review. Interviews were conducted until saturation was achieved.Results
Interview responses informed library planners about researchers’ key data issues.Conclusions
This approach proved valuable for planning data management products and services and raising library visibility among clients in the research data realm. 相似文献64.

While education communities have well defined commitments to protect their learners from oppressive instructional materials,
discourses of science education are often left unexamined. This analysis/critique employs queer theory as a perspective to
look at how one widely used textbook in Ontario schools conceptualizes notions of gender and sexuality. Results indicate the
use of discourses that promote exclusively heteronormative constructions of sexuality along with sex/gender binaries. Challenging
such oppressive misconceptions of sex/gender and sexuality is discussed. 相似文献

Infant Attachment Security and Early Childhood Behavioral Inhibition Interact to Predict Adolescent Social Anxiety Symptoms 下载免费PDF全文

Insecure attachment and behavioral inhibition (BI) increase risk for internalizing problems, but few longitudinal studies have examined their interaction in predicting adolescent anxiety. This study included 165 adolescents (ages 14–17 years) selected based on their reactivity to novelty at 4 months. Infant attachment was assessed with the Strange Situation. Multimethod BI assessments were conducted across childhood. Adolescents and their parents independently reported on anxiety. The interaction of attachment and BI significantly predicted adolescent anxiety symptoms, such that BI and anxiety were only associated among adolescents with histories of insecure attachment. Exploratory analyses revealed that this effect was driven by insecure‐resistant attachment and that the association between BI and social anxiety was significant only for insecure males. Clinical implications are discussed. 相似文献

The aging of the Baby Boom presents long-term care with many new challenges. Among these are the historically high levels of drug use by this cohort. This study surveyed administrators of licensed skilled nursing facilities in the Commonwealth of Kentucky regarding their perception of current drug use by residents, facility policies and procedures currently in place regarding illicit drug use, and their attitudes toward use of illicit drugs by residents. The results of interviews with 40 administrators or their designees revealed that they have experienced little problem with use or abuse of illegal drugs by residents. Fewer than one-third of the facilities had formal policies in place regarding illegal drug use. Only 10% had any experience with requests for medical marijuana, but almost one in five had a policy on the matter and nearly one-third stated they would support medical marijuana use by some of their residents if the matter arose. These authors recommend the following: (a) that the issue of illicit drug use needs to be addressed now before the situation becomes critical, (b) that administrators and staff need to be educated about recreational drug use and appropriate responses to drug abuse, (c) that screening instruments for drug abuse in this population should be developed and implemented, and (d) that policies regarding medical marijuana need to be adopted by all such facilities. 相似文献

Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White; collected from 2007 to 2017 near Philadelphia) were analyzed at 6, 12, and 24 months. At 12 months, HR-ASD infants produced fewer vocalizations than HR-Neg infants. From 6 to 24 months, HR-Neg infants demonstrated steeper vocalization growth compared to HR-ASD and LR infants. Finally, among HR infants, vocalizing at 12 months was associated with language, social phenotype, and diagnosis at age 2. Infant vocalizing is an objective behavioral marker that could facilitate earlier detection of ASD. 相似文献
