Ten teachers, from preschool to secondary school have tried out puppets as a stimulus in science lessons. Data were gathered by teachers answering a questionnaire and by interviewing the teachers. We report what teachers have experienced by using puppets in science classrooms and in science activities in preschools. Data indicate that the puppet can be used to stimulate science both in preschool, primary school and secondary school. Probably the puppet must be used in different ways in preschool and primary school than in secondary school to get the pupils to accept them. This pilot study has given us courage and ideas to start a following-up study in using puppets in science. 相似文献

Increasing accountability and efficiency in the use of public and out-of-pocket financing in education are critical to realizing the maximum impact of the meager allocations to education in most developing countries. While broad estimates and numbers are routinely collected by most national ministries and state departments of education, the lack of accuracy and reliability as well as the obtuse nature of recording and presentation of the data does not facilitate any serious policy use. A major advance in this area has been brought about by the development of NEA （National Education Accounts）, which is a new tool for measuring education expenditures in a systematic policy-~endly manner. In essence, NEAs measure the ＂financial pulse＂ of an education system, answering 4 key questions： Who is financing education？ How much do they spend？ How are funds distributed across different education providers, levels and activities？ Who benefits from or receives the services？ NEAs gather information on all spending from public, private and donor sources, and provide a snap-shot of all expenditures on education in the state or country. While not an auditing tool, it provides real time information on the flow of funds that can be used for evidence-based decision-making. It provides information to policy-makers, enabling them to discern systcm-wide inequities and identify areas that require changes in policy. In addition, the use of a standard classification of expenditures allows for data from NEAs to be comparable between and within countries. This paper provides an assessment of accountability and efficiency in the use of public and private resources in the education sector in 2 states of Nigeria. Using comparative data from implementation of education accounts in 2 states of Nigeria, it presents a breakdown of education spending by public and private sources as well as donor agencies, by types of providers, by geographical regions and by category of expenditures. It analyzes educational expenditures for the 2 states in the context of state government priorities for education, and proposes a novel way of tracking trends in education spending as a means for policy-makers to organize a strategic vision supported by resources and to evaluate the outcome of policies. 相似文献

It is becoming more and more apparent that globalization processes represent, theoretically as well as practically, a challenge for educational sciences and therefore, it must be addressed within the sphere of education. Accordingly, educational conceptions have to adapt to globafization phenomena and focus more on alternative and innovative educational concepts. The observable phenomena that appear as part of globalization then lead to the following question： Is there still space for educational concepts like emancipation, self-determination, equal opportunities and fairness in distribution, democracy and common sense？ The most indispensable tools for the development of equitable and peaceful contemporary education perspectives are a differentiated reflection on globalization phenomena and consequences, an intensive analysis and disclosure to address （global） conflict lines, the questioning of well-established concepts, the formation and embodiment of visions of the global future and the articulation of innovative education concepts. Modern social and political structures and practices have to be reoriented to combat the negative effects of globalization processes through the incorporation of more humane, socially fair and ecological principles. Educational science is sure to make an important contribution in making this a reality. 相似文献

The study aimed to assess and compare the values prevalent among the students and teachers of Universities in Bangladesh, Japan, USA and Germany. The sample consisted of 480 students and 236 teachers. The sample included 120 undergraduate students Japan; 120 undergraduate students from Bangladesh; 120 undergraduate students from USA, and 120 undergraduate students from Germany. The faculty sample included 60 teachers from Japan, 60 teachers from Bangladesh; 60 teachers from USA, and 56 teachers from Germany. To identify the value preferences of the individuals a list of 10 values, pro-social, achievement, power over others, security, self direction, otherworldliness, fatalism, narcissism, inner directed, and conservative, based on previous values studies by Singh and Parek were prepared. The first five values were identified in previous studies as functional （Singh, 1975） and other five were identified as dysfunctional （Parek, 1988） in the context of national development of Asian cultures. The results revealed that Bangladeshi students held stronger preferences for values identified as functional values than for those identified as dysfunctional. Japanese students indicated stronger preferences for the values identified as functional values except narcissism. The American students indicated a preference for three of the five values identified as functional but also ranked narcissism and other worldliness as third and fifth preferred values respectively. German student showed a preference for functional values, except narcissism which they also ranked as third. Bangladeshi teachers＇ preferences for functional values were higher than dysfunctional values. Japanese teachers indicated a preference for functional values except narcissism. American teachers preferred functional values except other worldliness. German teachers＇ value preferences were also functional, except for narcissism which they ranked as fifth. Students and teachers in the four countries sampled indicate preferences for values identified as functional with few exceptions. This research suggests that value preferences among university students and teachers are more similar than different, suggesting a homogenizing effect （Boli, 2005） on human values. 相似文献

This article discusses the teaching of life skills to urban American youths who are highly fascinated with the hip-hop culture--songs, raps, miming, lyrics, dressing and musical rhythms, especially individuals with emotional disabilities in the public schools. This is an instructional curriculum strategy to encourage positive and active participation of these students, promote perfect school attendance, encourage good behaviors, deal with anger management and motivate committed learning in the classroom. The instructors＇ understanding of students＇ culture, learning needs and styles, and using such background knowledge to educate them become imperative in this setting. These urge for innovative and leadership projects in the author＇s special education classroom necessitated the application of hip-hop music to teach life skills, reading and other functional skills in the classroom. The outcome was positive and rewarding to both the teachers and students. There are recommendations for interested teachers to devise creative teaching methods, differentiated instruction and appropriate classroom management practices to attain student achievement. 相似文献

Over the last 2 decades, Irish schooling and society have gone through a period of significant structural and policy-driven change. To meet the emerging needs of the knowledge/learning society, schools and teachers are challenged to develop their capacities as ＂active learning communities＂. This places greater demands on teachers and schools to reflect on their classroom practices, to utilise a wider repertoire of pedagogic styles more suited to the needs of the 21st century learners and so that meaningfully collaborate with their fellow professionals. Teaching and Learning for the 21st Century （TL21） was a 4-year （2003-2007） multi-pronged research and development project involving the Education Department at the National University of Ireland, Maynooth （NUIM） and 15 post-primary schools. The project sought to address a number of key aims in terms of developing schools as professional learning communities, including addressing the isolation and insulation which teachers can, and do experience in their day-to-day professional lives and prioritize quality in teaching and learning as a key challenge for school development planning. This paper attempts to succinctly frame the key developments and findings which emerged over the duration of this process. 相似文献

This paper reveals a new evaluation model, which enables educational program and project managers to evaluate their programs with a simple and easy to understand approach. The ＂index of success model＂ is comprised of five parameters that enable to focus on and evaluate both the implementation and results of an educational program. The integration of these parameters forms a complete and comprehensive picture, which in turn provides the most information on the success or failure of the program. The parameters are： （1） the relevance index, referring to an evaluation of predefined objectives; （2） the efficiency index, referring to the fiscal efficiency of the program; （3） the effectiveness index evaluating the attainment of the program＇s objectives; （4） the impact index gauging the effect on the consumers, for whom the program is undertaken; and （5） the final parameter is the program＇s sustainability index. Since Israel＇s education strategy currently leans towards site-based monitoring and evaluation, such a model can potentially be of great help to school management and staff. 相似文献

The objective of this paper is to explore the operation of magnet and professional development school （PDS） programs in a real life situation using an ethnographic study of Downtown Elementary School （DES-a pseudonym） that simultaneously operates as a PDS and a magnet school. The author spent almost three years at DES, located in the Southern United States, collecting data through participant observation, interviewing, and document collection. The purpose is to provide answers to compelling questions such as： What does it mean to have both magnet and PDS programs operating simultaneously in the same school as in the case of DES？ What can be learned from the experiences of the unique school-DES？ The paper provides an outline of both magnet and PDS programs and their operations at DES and analyzes how these programs are interrelated and intertwined. Some of the outcomes indicate that DES is about the only school in its locality that juxtaposes two innovative school reform programs. These programs impede each other＇s progress sometimes and in some cases feed off each other. There is a lot to be learned from the unique experiences of DES. Coupled with other conclusions, the author concludes that, PDSs, as school restructuring projects are intertwined with magnet schools＇ reform activity which is motivated by the drive to provide equity of opportunity to learn, particularly for poor, minority and black students in mostly urban areas who are at a disadvantage for various reasons. The final section of the paper takes a critical look at the issues at stake through the lens of critical multiculturalism. 相似文献

Facilitating adult learning and a researcher identity through a higher education pedagogical process
Lisa L. Wright Lange Elizabeth Da Costa Jose 《美中教育评论》2009,6(11):1-16
This empirical study uses auto-ethnography to describe a higher education pedagogical process that facilitated largely doctoral students in preparing their candidacy proposals through the use of specific adult learning principles. Students＇ experiences and points of view of such a learning environment were explored, including： （1） how they contributed to their peers＇ learning; （2） how their peers contributed to their own individual learning; and （3） how the learning environment impacted the process. Key factors identified as pivotal to learning to learn, include creating a learning sanctuary and trusting relationships, engaging in mutual inquiry and the co-construction of meaning, and bridging research theory and practice. These factors enabled students to expand their identities to include a researcher identity and to negotiate deep knowledge at the personal level. Throughout this article, the students＇ points of view are used to elucidate shared and diverse experiences, in addition to supporting conclusions and recommendations for practice and further study. 相似文献
