This article shares examples of how leadership opportunities, self-directedness, self-efficacy and self-determination developed in professional women who have been recognised as leaders. This study presents six women honoured as ‘Women of Achievement’. Through narrative interviews, each woman described aspects of her life that guided decision-making and her approach to various life situations. Using the narrative examples provided, one may be able to see themes or strategies for working with other learners to enhance their own leadership. Findings included: growth and development as leaders within their own environments and through interactions with people who mentored or influenced them; openness to opportunities presented to them; the effect that time, place and culture contributed to the goals and tasks that these women undertook. While they were bound by social constraints concerning gender, race and class, each found a way to adapt within those environments and make changes for the better through their contributions. Consistently, these women realised their actions made a difference. Implications for further research include: enhancing self-directedness, self-efficacy and self-determination in women; expanding the definition of leadership; and understanding the motivation for engaging in leadership opportunities. Through this and other research, we seek to expand women’s roles and participation as leaders.  相似文献

Unhealthy diets, lack of fitness, and obesity are serious problems in the United States. The Centers for Disease Control, Surgeon General, and Department of Health and Human Services are calling for action to address these problems. Scientists and educators at Baylor College of Medicine and the National Space Biomedical Research Institute teamed to produce an instructional unit, “Food and Fitness,” and evaluated it with students in grades 3–7 in Houston, Texas. A field-test group (447 students) completed all unit activities under the guidance of their teachers. This group and a comparison group (343 students) completed pre and postassessments measuring knowledge of concepts covered in the unit. Outcomes indicate that the unit significantly increased students'' knowledge and awareness of science concepts related to energy in living systems, metabolism, nutrients, and diet. Pre-assessment results suggest that most students understand concepts related to calories in food, exercise and energy use, and matching food intake to energy use. Students'' prior knowledge was found to be much lower on topics related to healthy portion sizes, foods that supply the most energy, essential nutrients, what “diet” actually means, and the relationship between body size and basal metabolic rate.  相似文献

Although there is a growing body of literature on counselor impairment, the topic of supervisor impairment has surprisingly been overlooked. The author explores the implications of working with an impaired supervisor at various levels of counselor development and discusses some of the critical factors that may influence how a supervisee decides to handle this problem. In addition to discussing the misuse of power by the impaired supervisor, other factors (e.g., the nature and severity of the supervisor's impairment) are also discussed. The author presents an ethical decision‐making model that can be used to guide the counselor trainee through the arduous process of determining a viable course of action.  相似文献

The largest post graduate initial teacher education course in the UK was introduced by the Open University in February 1994. The course is innovative in a number of ways: it is the first large scale distance taught pre‐service course in the UK; all students are loaned a computer for the duration of the course; and computer conferencing is used extensively for communication between students, part‐time tutors and the course team. In this paper the use of the computer conferencing element is described and evaluated, and ways in which electronic communications can be developed for this to be a truly effective medium for supporting the development of beginning teachers’ competence and confidence are discussed.  相似文献

This paper attempts to engage the field in a discussion about what mathematics is needed for students to engage in society, especially with an increase in technology and digitalization. In this respect, mathematics holds a special place in STEM as machines do most of the calculations that students are taught in K-12. We raise questions about what mathematical proficiency means in today’s world and what shifts need to be made in both content and pedagogy to prepare students for 21st Century Skills and mathematical reasoning.  相似文献

This paper explores the role that technology can play in engaging pre-service teachers with the iterative, “messy” nature of model-based inquiry. Over the course of 5 weeks, 11 pre-service teachers worked in groups to construct models of diffusion using a computational animation and simulation toolkit, and designed lesson plans for the toolkit. Content analyses of group discussions and lesson plans document attention to content, representation, revision, and evaluation as interwoven aspects of modeling over the course of the workshop. When animating, only content and representation were heavily represented in group discussions. When simulating, all four aspects were represented to different extents across groups. Those differences corresponded with different planned uses for the technology during lessons: to teach modeling, to engage learners with one another’s ideas, or to reveal student ideas. We identify specific ways in which technology served an important role in eliciting teachers’ knowledge and goals related to scientific modeling in the classroom.  相似文献

Indirect effects of preschool classroom indexes of teacher talk were tested on fourth-grade outcomes for 57 students from low-income families in a longitudinal study of classroom and home influences on reading. Detailed observations and audiotaped teacher and child language data were coded to measure content and quantity of verbal interactions in preschool classrooms. Preschool teachers' use of sophisticated vocabulary during free play predicted fourth-grade reading comprehension and word recognition (mean age=9; 7), with effects mediated by kindergarten child language measures (mean age=5; 6). In large group preschool settings, teachers' attention-getting utterances were directly related to later comprehension. Preschool teachers' correcting utterances and analytic talk about books, and early support in the home for literacy predicted fourth-grade vocabulary, as mediated by kindergarten receptive vocabulary.  相似文献

The effect of childhood trauma, psychiatric diagnoses, and mental health services on school dropout among U.S.-born and immigrant youth is examined using data from the Collaborative Psychiatric Epidemiology Surveys, a nationally representative probability sample of African Americans, Afro-Caribbeans, Asians, Latinos, and non-Latino Whites, including 2,532 young adults, aged 21-29. The dropout prevalence rate was 16% overall, with variation by childhood trauma, childhood psychiatric diagnosis, race/ethnicity, and nativity. Childhood substance and conduct disorders mediated the relation between trauma and school dropout. Likelihood of dropout was decreased for Asians, and increased for African Americans and Latinos, compared to non-Latino Whites as a function of psychiatric disorders and trauma. Timing of U.S. immigration during adolescence increased risk of dropout.  相似文献
