For many students, school is a place that makes no sense; a place where students’ interests are not reflected in the curriculum. Using mixed methods research, we developed an instrument that identifies student interests. This instrument was applied in a pilot study that considered 10th-grade students from three schools in Santiago, Chile. We compared student interest and national curriculum for different factors and established how well aligned these are. The results reveal that private school students prefer subjects that require greater cognitive development, related to Young’s powerful knowledge. Students from voucher schools, on the other hand, prefer to develop their knowledge of the arts and physical education, both of which are subjects they tend to enjoy. These findings are coherent with Bernstein’s theories. This pattern is also repeated when comparing high-performing students with their low-performing counterparts, regardless of school type. The findings of this study not only help identify which subjects the students want to study, but also to understand the reasons behind their preferences. Understanding these reasons is key for developing a more contextualised curriculum that makes more sense to the students.  相似文献

The present research used a preferential‐reaching task to examine whether 9‐ and 11‐month‐olds (n = 144) could infer the relative weights of two objects resting on a soft, compressible platform. Experiment 1 established that infants reached preferentially for the lighter of 2 boxes. In Experiments 2–4, infants saw 2 boxes identical except in weight resting on a cotton wool platform. Infants reached prospectively for the lighter box, but only when their initial exploratory activities provided critical information. At 11 months, infants succeeded as long as they first determined that the platform was compressible; at 9 months, infants succeeded only if they also explored the boxes and thus had advance knowledge that they differed in weight.  相似文献

The present paper explores middle‐class fathers’ educational work by studying how they and their partners are involved in their children’s education at home, in school, and how they investigate school options and make decisions about educational issues. Drawing on data from an ethnographic study of 30 dual‐earner couples in the Greater Los Angeles area, this article analyses how fathers position themselves in relation to discourses on parental involvement in education. In order to demonstrate the variety of ways fathers are involved three case studies are presented. It is illustrated how the men, by drawing on a discourse on involved fatherhood, position themselves in line with an ideal of parental involvement in education. Fathers who are doing less educational work than their spouses offer accounts for not taking a greater educational responsibility by drawing on a breadwinner discourse or by depicting mothers as gatekeepers of father involvement.  相似文献

Abstract

Although stakeholder participation is expected to promote equitable and sustainable natural resource management, lessons from the past tell us that more careful attention needs to be paid to achieving equitable impacts. Now the question is how to address social inequities and power asymmetries. Some authors emphasize the need for more dialogue, while others prefer a critical perspective, arguing that dialogue might not be sufficient to avert the risk of a process deepening existing social inequities. This article aims to enrich this debate and question the practical implications of the critical perspective through an in-depth analysis of power games in a participatory process.

A Companion Modelling (ComMod) process was conducted in an Akha community of Northern Thailand with a critical perspective, i.e. with a concern for the less influent stakeholders. Simulation tools such as role-playing games were used to mediate a cross-cultural learning process among researchers, farmers and administrators about a local irrigation water management problem. The detailed analysis of power games in this learning and negotiation process reveals that in spite of initial power asymmetries, the poorest farmers of the community started to voice and assert their interests. This was very much due to the role of a Western researcher who put the equity issue on the public agenda and to the strategic support of a charismatic Christian leader.

We identify a set of practical facilitation methods that helped to manage power asymmetries and to level the playing field, but we also discuss the main limits of our cultural-embedded methodological choices. Acknowledging that ‘the facilitators’ neutrality' is an illusion, this study allows us to raise the question of their social legitimacy. We suggest that they should systematically make explicit and reflect on their cultural-ideological background and methodological hypothesis and choices and their effects on the socio-political context. This article is an original attempt to accept this challenge.  相似文献

We develop a new transmission scheme for additive white Gaussian noisy (AWGN) channels based on Fuchsian groups from rational quaternion algebras. The structure of the proposed Fuchsian codes is nonlinear and nonuniform, hence conventional decoding methods based on linearity and symmetry do not apply. Previously, only brute force decoding methods with complexity that is linear in the code size exist for general nonuniform codes. However, the properly discontinuous character of the action of the Fuchsian groups on the complex upper half-plane translates into decoding complexity that is logarithmic in the code size via a recently introduced point reduction algorithm.  相似文献

The purpose of this paper is two fold: first, to tease out the meaning inherent in the correlativity of the question and answer process and second, to suggest a philosophical answer to the question “What does it mean to question?” in the context of teacher education. To that end, we want to claim that R.G. Collingwood’s “Logic of Question and Answer” is a valuable tool in filling the gap in scholarship concerning the art of questioning. While research into the activity of teaching often emphasizes the role and effectiveness of questioning, these studies have largely focussed on the strategies and results of the practice of questioning. We argue that they place too little emphasis on making sense of the process itself and that more time should be spent on the Logic of Question and Answer. To accomplish our goal, in Collingwoodian form, we will contextualize an example of how the understanding of the question and answer complex informs the practice of teacher education in the specific area of the Social Studies Methods Course.  相似文献

A study was performed to describe and analyze the conceptions about teaching and learning science held by different samples of teachers in Spain. The responses of 265 teachers (107 prospective teachers and 158 active teachers) to items from the Inventory of Scientific and Pedagogical Beliefs (Porlán, 1989) were subjected to multifactorial analysis. The results showed various tendencies in how the teaching/learning process is viewed, ranging from a predominant view based on the transmission-reception of knowledge to a minority constructivist view. There was a greater diversity of viewpoints among the in-service teachers than among the prospective teachers. In both samples, the most representative tendency was learning as appropriation of meanings, followed by a technical view of teaching among the prospective teachers and a more traditional view among the in-service teachers. Finally, some implications for teacher education are discussed.  相似文献
