Zebra finch song behavior is sexually dimorphic: males sing and females do not. The neural system underlying this behavior is sexually dimorphic, and this sex difference is easy to quantify. During development, the zebra finch song system can be altered by steroid hormones, specifically estradiol, which actually masculinizes it. Because of the ease of quantification and experimental manipulation, the zebra finch song system has great potential for use in undergraduate labs. Unfortunately, the underlying costs prohibit use of this system in undergraduate labs. Further, the time required to perform a developmental study renders such undertakings unrealistic within a single academic term. We have overcome these barriers by creating digital tools, including an image library of song nuclei from zebra finch brains. Students using this library replicate and extend a published experiment examining the dose of estradiol required to masculinize the female zebra finch brain. We have used this library for several terms, and students not only obtain significant experimental results but also make gains in understanding content, experimental controls, and inferential statistics (analysis of variance and post hoc tests). We have provided free access to these digital tools at the following website: http://mdcune.psych.ucla.edu/modules/birdsong. 相似文献

Despite extensive experience teaching residents, surgeons are an untapped resource for educating medical students. We hypothesized that by involving surgeons as teachers earlier in the medical school curriculum, medical students' interest in surgery will increase and their opinions of surgeons will improve. Five programs designed to involve surgeons as educators in the medical school curriculum were implemented. The first program, started in 2008, introduced surgical faculty into the first-year medical student anatomy dissection laboratories. Other programs initiated in 2008 included: Surgical Clinical Correlates in Anatomy, which involved faculty teaching through cadaver surgery; Clinical Pathologic Conferences in Anatomy, a surgeon-led conference based on clinical cases; and a women's faculty-student mentorship program. Table Rounds, a surgeon-led anatomy review that used clinical scenarios to quiz students was begun in 2009. All five programs were successfully integrated into the medical school curriculum. While student opinion of surgeons as educators improved, there were no significant changes in student interest in surgery as a career nor change in performance on written examinations over the Anatomy content covered by the surgeons. Surgical faculty and trainees can be integrated into the medical school curriculum. Involving surgeons as educators earlier in the medical school curriculum may have longer term effects than could be observed in this study. At a minimum, the experience improved student opinion of surgeons as educators. 相似文献

To understand the experiences and views of childbearing women in the United States and trends over time, Childbirth Connection carried out the third national Listening to Mothers survey among 2,400 women who gave birth in U.S. hospitals to a single baby from mid-2011 to mid-2012 and could participate in English. A follow-up survey directed to the same participants explored postpartum experiences, in depth and well into the second year after birth; views about maternity care; and some additional pregnancy and birth items. Harris Interactive conducted the surveys using a validated methodology that includes data weighting to ensure that results closely reflect the target population. The follow-up survey was reported in Listening to Mothers III: New Mothers Speak Out. 相似文献

Supported reflective practice: a programme of peer observation and feedback for academic teaching development 总被引:3,自引:0,他引:3
Maureen Bell 《International Journal for Academic Development》2013,18(1):29-39
The outcomes of the evaluation of a structured, peer-supported teaching development programme for academic staff are reported. Supported reflective practice forms the conceptual framework for the programme, which includes feedback on observed teaching and feedback on reflection. Key themes identified are the effectiveness of the supported reflective practice process, improvements to teaching practice, developing confidence and congruent espoused theory and theory-in-use, ongoing professional development and developing collegiality. Factors that facilitate the programme are explored, including the support triangle, the role of the educational developer in providing feedback and monitoring, and the role of the support colleague. Suggestions for implementation of similar programmes are offered. 相似文献

According to the Lexical Restructuring Model (Metsala & Walley, 1998), children move from holistic representations of words, to syllabic representations, and finally to phonemic representations through a restructuring process driven by their developing lexical base. In contrast, the psycholinguistic grain size theory put forth by Ziegler and Goswami (2005) suggests that the awareness of individual phonemes is not possible without direct literacy instruction. The purpose of this study was to examine whether semantic knowledge and/or knowledge of grapheme/phoneme correspondences influenced the acquisition of word-blending skills by a sample of children with a reading disability. Participants were 211 second-grade and third-grade students from public elementary schools who were assigned to a reading intervention. Hierarchical Linear Modeling techniques were used to model individual growth curves of word-blending skills. Overall, findings support the psycholinguistic grain size theory of reading and suggest that instruction in the relationship between orthographic patterns and their corresponding sounds is necessary for the development of phonological awareness. 相似文献

Abstract This article addresses questions raised in the past decade regarding the role of child development knowledge for teaching and teacher preparation. Missing from the dialogue on this issue have been the voices of the students enrolled in teacher preparation programs. Accordingly, 77 preservice teachers were surveyed at the conclusion of a child development theory course. The results were examined for themes regarding how preservice teachers come to understand the changing nature of child development, the strengths and limitations of generalized theories of development, and the applicability of child development theory to their future practice. 相似文献
