"图层方法"是利用地理信息系统图层的概念和技术来开展地理教学的方法,具有直观性、形象化和可操作的特点,已被我国地理教师用于地理原理性知识和区域地理等内容的教学。该方法可以非计算机的"低技术"方式使用,既利用了地理信息系统中的有益方法,又适合我国地理教学软、硬件普遍不足的现状;对该方法的研究有利于挖掘"图层方法"的内涵,丰富中学地理教学方法体系,为地理教师提供更多的教学方法的选择。 相似文献

This paper explores the issue of the respectability and changing image of public school teachers through interviews with 114 teachers of color in three urban school districts: Cincinnati, Ohio; Seattle, Washington; and Long Beach, California. Almost one half of the respondents felt that either the negative image or the low status of teaching was one of the main reasons that students of color are not entering the profession. This assessment seemed to have little to do with money and a great deal to do with self-respect as defined in terms of dress, posture, and class. There was strong consensus that a professional image is important to people of color. The judgment that there has been a decline in respect for teaching was mixed. Many informants perceived themselves as leaders within their communities and as professionals and claimed that their people and their families did respect teachers. The problem seemed to lie less with communities of color and more with the dominant society, which devalues teaching. 相似文献

Mixed or hybrid method has become an increasingly popular course delivery model in recent years, but research regarding the effect of mixed learning is limited because of its recent debut in the landscape of educational technology. This one-year exploratory study looked at 78 elementary teacher candidates' view of learning in four mixed courses that used Blackboard Learning Management System (LMS) to supplement as well as replace some portions of face-to-face instruction. Both quantitative and qualitative data were collected from surveys designed to measure students' satisfaction and perspectives of hybrid learning. Results suggested high level of satisfactions but also revealed several important issues and complexities involving hybrid course implementation. 相似文献

This paper illustrates the use of exploratory focus groups to inform the development of a survey instrument in a sequential phase mixed-methods study investigating differences in secondary students’ career choice capability. Five focus groups were conducted with 23 Year 10 students in the state of New South Wales, Australia. Analysis of the focus group data helped inform the design of the instrument for the second phase of the research project: a large-scale cross-sectional survey. In this paper, we discuss the benefits of using focus groups as an initial exploratory phase in a sequential phase mixed-method design and demonstrate how the findings from this initial exploratory phase informed the development of the survey questionnaire to be used in the main phase of the research. The paper will be of interest to researchers considering the use of exploratory qualitative methods to enhance the quantitative phase in a mixed-methods study. 相似文献

This paper presents findings from an exploratory survey of teachers' perceptions, understanding, and use of pupil performance data in English secondary schools and examines the extent to which these are associated with school-level performance and a range of factors, including teachers' positions of responsibility. The survey was supplemented by a series of in-depth interviews. Use and availability of pupil performance data was found to be widespread, but classroom teachers reported significantly lower levels of use and understanding. The research also reveals a data-use hierarchy in schools, with many indicating that some data are accessible only to school leaders or provided pre-interpreted. Most teachers make regular use of their own sources of pupil data, which is seen as at least as useful as “official” data, which poses challenges for policymakers in raising levels of use and creating a “mixed economy” of sources. 相似文献
