Depression in mothers is a significant risk factor for the development of maladjustment in children. This article focuses on modifiable risk processes linking depression in mothers and adaptation in their young children (i.e., infancy through preschool age). First, the authors present evidence of the efficacy of interventions for reducing the primary source of risk: maternal depression. Second, they describe a central mechanism—parenting behaviors—underlying the relation between maternal depression and children's adjustment. Third, the authors recommend two different integrated interventions that successfully treat mothers’ depression and enhance parenting skills with infants and young children. Finally, the authors note the possible need for supplementary interventions to address severity and comorbidity of mothers’ depression, barriers to engaging in treatment, and the sustainability of program benefits.  相似文献

This essay aims to shed new light on the relations between physiology and psychology in the late nineteenth and early twentieth centuries by focusing on the use of unicellular organisms as research objects during that period. Within the frameworks of evolutionism and monism advocated by Ernst Haeckel, protozoa were perceived as objects situated at the borders between organism and cell and individual and society. Scholars such as Max Verworn, Alfred Binet, and Herbert Spencer Jennings were provoked by these organisms to undertake experimental investigations situated between general physiology and psychology that differed from the physiological psychology advocated by Wilhelm Wundt. Some of these investigations sought to locate psychological properties in the molecular structure of protoplasm; others stressed the existence of organic and psychological individuality in protozoa. In the following decades, leading philosophers such as Friedrich Nietzsche, Charles Sanders Peirce, and Henri Bergson, as well as psychological researchers like Sigmund Freud, integrated the results of these investigations into their reflections on such problems as the nature of the will, the structure of the ego, and the holistic nature of the reactions of organisms to their environment.  相似文献

Preschool children (N = 104) read a book that described and illustrated color camouflage in animals (frogs and lizards). Children were then asked to indicate and explain which of 2 novel animals would be more likely to fall prey to a predatory bird. In Experiment 1, 3- and 4-year-olds were tested with pictures depicting animals in camouflage and noncamouflage settings; in Experiment 2, 4-year-olds were tested with real animals. The results show that by 4 years of age, children can learn new biological facts from a picture book. Of particular importance, transfer from books to real animals was found. These findings point to the importance that early book exposure can play in framing and increasing children's knowledge about the world.  相似文献

It is broadly acknowledged that leaders in the twenty-first century are required to navigate an increasingly complex landscape and that the types of challenges individuals and organisations face in the knowledge era require the capacity to adapt and respond to continual fluctuations and change. Outcomes from previous leadership research, combined with the perspectives of colleagues and observation over the past decade, prompted concern that leadership in higher education (HE) institutions was, in the main, not demonstrating the level of readiness or capability to effectively respond to the challenges embodied in the transition to the knowledge era. In seeking to establish how well founded this concern was, this study, supported by a Peter Karmel International Travel Grant, investigated leadership development thinking, programmes and practices within the HE sector in the United States of America and the United Kingdom, and explored how this applies within the Australian context. A number of themes emerged that support the idea that the work of leadership will ideally be based on relationships rather than the ‘command and control’ models of the past and on distributed leadership processes and practices throughout the organisation.  相似文献

This article describes the introduction of a virtual microscope (VM) that has allowed preclinical histology teaching to be fashioned to better suit the needs of approximately 900 undergraduate students per year studying medicine, dentistry, or veterinary science at the University of Bristol, United Kingdom. Features of the VM implementation include: (1) the facility for students and teachers to make annotations on the digital slides; (2) in‐house development of VM‐based quizzes that are used for both formative and summative assessments; (3) archiving of teaching materials generated each year, enabling students to access their personalized learning resources throughout their programs; and (4) retention of light microscopy capability alongside the VM. Student feedback on the VM is particularly positive about its ease of use, the value of the annotation tool, the quizzes, and the accessibility of all components off‐campus. Analysis of login data indicates considerable, although variable, use of the VM by students outside timetabled teaching. The median number of annual logins per student account for every course exceeded the number of timetabled histology classes for that course (1.6–3.5 times). The total number of annual student logins across all cohorts increased from approximately 9,000 in the year 2007–2008 to 22,000 in the year 2010–2011. The implementation of the VM has improved teaching and learning in practical classes within the histology laboratory and facilitated consolidation and revision of material outside the laboratory. Discussion is provided of some novel strategies that capitalize on the benefits of introducing a VM, as well as strategies adopted to overcome some potential challenges.

Abstract

In the present study the relationship between teaching and learning was examined using a conceptual framework that links dimensions of instructional tasks with gains in student learning outcomes. The greatest student gains on a performance assessment consisting of tasks that require high levels of mathematical thinking and reasoning were related to the use of instructional tasks that engaged students in the “doing of mathematics” or the use of procedures with connections to meaning. In addition, student performance gains were greater for those sites whose tasks were both set up and implemented to encourage the use of multiple solution strategies, multiple representations, and explanations. Whereas, student performance gains were relatively small for those sites whose tasks tended to be both set up and implemented in a procedural manner and that required a single solution strategy, single representations, and little or no mathematical communication.  相似文献

A high impact mentoring program at a community college connected professionals from the special education and early intervention fields with small groups of teacher education students. Two federal grants from U.S. Department of Education funded tuition scholarships and mentoring for 76 Special Education students and 78 Early Childhood Education/Early Intervention students in associate degree programs. The mentor programs consisted of individual monitoring by project staff, consistent contact with a mentor from the professional community and with other students in mentor groups, and structured monthly dinner meetings. Students who participated in the mentoring programs showed increased persistence and higher grade point average when compared with the general population of similar majors. Within each grant-funded population, students who showed low participation in the mentor programming presented lower retention rates and lower GPA than grant-funded students who took full advantage of the mentoring program.  相似文献
