This article reports on an analysis of the process in which knowledge to be taught was transposed into knowledge actually taught, concerning a task including proportional relationships in an algebra setting in a grade 6 classroom. We identified affordances and constraints of the task by describing the mathematical praxeology of the two different types of knowledge exposed, in the task as such and in the activity of the classroom. Through the teacher’s explicit process of reasoning, modeling, revising, solving, and repeatedly explaining the task, we found that the transposition of knowledge was seriously affected by the contextualization of the task. Modeling word problems about everyday situations has its limitations and can, as in this case, make the problem unsolvable unless it is accepted as a “textbook task” disguised as real but adjusted to the norms of school mathematics. Such constraints may obscure mathematical ideas afforded by the task. We conclude that learning opportunities embedded in a task do not necessarily surface when a task is treated in a classroom setting. 相似文献

One hundred and twelve preschool teachers in Indiana were asked to complete a questionnaire requesting them to indicate what
personal health-related activities they were incorporating into their classroom routines, why they were incorporating them,
and how often such activities were done. The results of the study indicate that the most incorporated activities were hand-washing,
proper ways of coughing, and discussion on germs. The least incorporated personal health-related activities were proper use
of bathroom and keeping things out of the mouth. Reasons for incorporating the activities include helping to curtail the spreading
of colds and germs, helping the children to develop good life skills later in life, and helping the preschoolers know about
the health hazards associated with germs, among others. The study recommends the need to make Health Education a core component
of preschool teachers’ training. 相似文献

Empirical research in progressive education 总被引:1,自引:0,他引:1
While the development of empirical psychology was helpful for research in several fields of schooling, progressive education gained much from the diverse branches of child studies in the late 19th and early 20th Centuries. There are several outstanding examples like G. Stanley Hall, Jean Piaget and the Geneva Institute, and the German movement of “experimental pedagogy.” Progressive education was not constituted out of empirical research, but was in need of empirical research to secure and stabilize public interest in “new education”. Research activities were launched to secure older theories of child orientation, most of them referring to Rousseau and the “naturalistic approach” to education. Without this tradition progressive education could not have been developed. 相似文献

e-Government adoption model based on theory of planned behavior: Empirical validation 总被引:1,自引:0,他引:1
The e-Government phenomenon has become more important with the ever increasing number of implementations worldwide. A model explaining the e-Government adoption and the related measurement instrument – a survey – had been developed and validated in this study. In a post Technology Acceptance Model (TAM) approach, theory of planned behavior (TPB) was extended to fit the requirements of e-Government context. The adoption of student loans service of the higher education student loans and accommodation association of Turkey (KYK) was investigated to obtain data for empirical validation. The instrument was administered to over four-hundred students and partial least squares path modeling was employed to analyze the data. The results indicate that the model was an improvement over TAM in terms of predictive power. The constructs trust, perceived behavioral control and attitudes successfully explained the intention to use an e-Government service. The findings presented in this study provide useful insights for researchers and policy makers when dealing with e-Government services. 相似文献

The tensions between environmental protection and economic growth are critical to future well-being, and it is therefore important to understand how young people conceptualize these tensions. The aim of the present study is to explore students’ solutions to the dilemma of economic development and mitigating climate change, with regard to societal responses to the challenge of climate change. The study was conducted in China’s Green Schools. Green School is an international long-term programme with the aim of increasing students’ knowledge of environmental issues, and transferring this knowledge into positive actions to affect the wider community. The data were obtained through semi-structured pre- and post-interviews with 15–16-year-old students in three groups (12 students) from Green Schools in the Beijing area. The results show that students’ discussions focused exclusively on economic growth and social welfare. Students seem to believe that environmental problems are inevitable, nature is a ‘box’ of resources, and economic development is necessary in order to sustain and even improve nature. Therefore, there is no dilemma between economic development and environmental protection. The paper ends with a discussion on research and implications for teaching climate change. 相似文献

Pedagogy is the science and art of teaching. Each generation needs to explore the history, theory, and practice of the teacher–student interaction. Here we pave the path to develop a science that explores the cognitive and physiological processes involved in the human capacity to communicate knowledge through teaching. We review examples from our previous work in this research area and discuss a path to reveal the cognitive and cerebral mechanisms by which we teach, unfolding a complex operation such as teaching in its constituents and components. 相似文献
