This paper reports a classroom-based study involving investigation activities in a university numerical analysis course. The study aims to analyse students' mathematical processes and to understand how these activities provide opportunities for problem posing. The investigations were intended to stimulate students in asking questions, to trigger their thinking processes, to promote their ability to investigate and to support them in learning numerical analysis' concepts and procedures. The results show that the investigations provided opportunities for students to experience mathematical processes, including posing questions, formulating and testing conjectures and, to some extent, proving results. They also provide some understanding about the role of problem posing in these processes. Posing questions occurred mainly in an implicit way, in the interpretation of tasks and in identifying regularities, analysing graphs and testing cases. The conjectures were often based on pattern identification or data manipulation, and the students tended to accept them without testing or proving. The students also proposed alternative formulations for the initial questions and posed new problems from their explorations and attempts to refine previous conjectures. 相似文献

In this paper we study the mathematical body as an assemblage of human and non-human mathematical concepts. We argue that learners’ bodies are always in the process of becoming assemblages of diverse and dynamic materialities. Following the work of the historian of science Karen Barad, we argue that mathematical concepts must be considered dynamic material, and we suggest a “pedagogy of the concept” that animates concepts as both logical and ontological. We draw on the philosopher of mathematics Gilles Châtelet in order to pursue this argument, elaborating on the way that mathematical concepts partake of the mobility of the virtual, while learners, in engaging with this mobility, enter a material process of becoming. We show how the concept of virtuality allows us to look at mathematical concepts in school curriculum in new ways. 相似文献

Acquiring complex conceptual knowledge requires learners to self-regulate their learning by planning, monitoring, and adjusting the process but they find it difficult to do so. In one experiment, we examined whether learners need broad systems of support for self-regulation or whether they are also able to learn with more economical support configurations. Eighty-six undergraduate students with little prior domain knowledge learned plate tectonics from a multimedia presentation involving animation with concurrent narration and support in one of four forms: minimal support, two variants of intermediate support, or extensive support. After the presentation, participants solved retention and transfer tests. The results revealed that participants receiving the broadest system of support outperformed those in the other conditions, which did not differ from one another. This means that it is so difficult for learners to self-regulate learning that they need considerable support if they are to learn complex conceptual knowledge. 相似文献

This article analyses the background of teacher centres (CEPs) in Spain and presents the synthesis of conclusions drawn from the evaluation of such centres and continuous education in Andalusia (Spain), carried out according to the model of democratic evaluation defended by Barry McDonald. Three issues are dealt with: (a) the change of government policies concerning the running of teacher centres, from autonomy to control; (b) the changes in the way teachers' continuous education and advice strategies are understood; and (c) how teacher commitment to innovation and education reform evolved with time. All this takes place within the framework of political confrontations between the two main parties in Spain: the Socialists (PSOE) - who institutionalized the CEPs and created education reform, and who continue to govern in Andalusia - and the Conservatives (PP) - who are currently in power in central government and who neither supported educational reform nor the teacher centres. In this context, the analysis of the use of the CEPs as a political weapon in their confrontation is one of the main objectives of the evaluation. 相似文献

Across the literature, travelling has been viewed as a recurring activity for older adults and is driven by a multitude of purposes and reasons. Previous studies have probed touristic activities of older adults however, little is known about their emotional experiences specifically their sense of happiness when joining international group tours, hence this phenomenological study. A qualitative approach was utilized to gather data from a group of 15 purposively selected participants aged 60 years and above. A two-part instrument consisting of a robotfoto and a semi-structured interview was used in this study. Through vertical and horizontal analyses of the field text, this study afforded the development of The Spiraling Model of Aging Filipino Tourists’ Happiness. This model describes aging tourists’ happiness while travelling as a product of Shared Moments, Shared Culture, Shared Memories, and Shared Transcendence. Summarily, findings of this study may provide significant insights to service providers such as hotels, airlines and travel agencies across the globe in developing innovative marketing strategies that cater to this promising age group. Empirically, this study may stimulate further exploration in the field of Cognitive Psychology aimed at adding large-scale data regarding the study of emotions specifically older adults’ happiness when joining international group tours. 相似文献

While adherence to medication remains a problematic area in the care of chronically ill elderly, an extended model that incorporates the interaction of studied variables remains a blank spot. Anchored on Ajzen's Theory of Planned Behavior, this article details our efforts to develop and test a model of medication adherence among Filipino elderly relative to their medication belief, follow-up visits, consultation satisfaction, memory task, trust with physician, perceived stress, memory strategies, social support, memory load, depression, length of time taking the medication, number of conditions, and self-efficacy with medication adherence. Structural equation modeling (SEM) was employed to study causalities among all parameters. With the participation of 325 older adults located in District IV, Sampaloc, Manila, data needed were gathered through a multiaspect questionnaire consisting of a robotfoto, a memory strategy usage measure, an eight-scale Morisky Medication Adherence Scale, a 15-item Geriatric Depression Scale, a General Self-efficacy Scale, a Consultation Satisfaction Questionnaire, and a Perceived Stress Scale. Data were analyzed using AMOS version 19. Results revealed that depression, trust with physician, and number of conditions affect adherence positively, while event-based memory, consultation satisfaction, memory load, and external memory strategy affect it otherwise. Some suggested variables were found to have no impact at all. As this study reveals, careful consideration should be given to multiple factors, and their interrelationship should be examined well. Because many factors can influence medication adherence behavior of the elderly, and because the reasons for their noncompliance are also varied, multifaceted solutions must be developed. 相似文献

In many countries choice of school is an increasing concern for families and governments. In Spain and Chile, it is also associated with a long‐standing political cleavage on the regulation of large sectors of private‐dependent schools. This article analyses both the micro‐ and the macro‐politics of choice in these two countries, where low‐status 15‐year‐old students record a significant segregation. At the micro level, some evidence is provided that not only middle‐class skilful choosers but also the political representatives of private‐dependent schools manage to pursue their interests drawing on economic, social and cultural capital. At the macro level, evidence also shows that the lobbies defending private‐dependent schools can use and maintain these power resources. However, in some episodes collective action is an effective power resource for those who campaign in favour of a stricter regulation of these schools, but its influence is much difficult to maintain for longer periods. 相似文献

The continually rising percentage of the elderly population and the demand for geriatric nursing care are dramatically related. While it is true that most undergraduate programs prepare nurses for the care of geriatric patients, most receive limited academic preparation in the nursing curriculum (Williams & Mezey, 2000). This is particularly true in the Philippines where there is no stand-alone geriatric nursing course. This phenomenological study purports to capture the lived experiences of Filipino nursing students' dilemmas in geriatric care. Five Filipino senior nursing students and three clinical faculty from a comprehensive university in the Philippines were purposely chosen for the study. A two-part instrumentation was used. The first is the robotfoto, a Dutch term which means a cartographic sketch of the subject (Kelchtermans & Ballet, 2002). The second was a semi-structured face-to-face interview that was recorded with the consent of the participants. The full texts were phenomenologically reduced using a repertory grid to observe both cool and warm analyses, which facilitates the identification of unique conceptual clusters. Findings of this study have described the elements that define student dilemmas in geriatric care. The emerged Students' Dilemmas in Geriatrics Causality Quadrant (SDGCQ), which consists of (a) Foundational Deficit, (b) Psychological Deficit, (c) Relational-Attitudinal Deficit, and (d) Occupational Deficit, are valuable discussion points for needed reforms in the present-day nursing curriculum. 相似文献

ABSTRACTThe objective of this integrative literature review was to evaluate the quality of retirement planning programs described in the extant literature. This was accomplished through a qualitative analysis of methodological and efficacy criteria as described by Flay et al. (2005), Kazdin (2010, 2011 and Murta (2005). Several databases were consulted in searching for retirement program articles including: Academic Search Premier, Medline, PsycInfo, and Web of Science, among others. Retirement planning intervention articles published in English, Portuguese, and Spanish were considered, with a focus on their evaluation methods and results. Eleven studies were identified that described the procedures for both program implementation and intervention evaluation. Results revealed methodological shortcomings in the papers reviewed, with concerns being related to a lack of experimental or quasiexperimental approaches, a failure to use previously validated measurement instruments and longitudinal assessments, and insufficiently robust data analysis procedures. That said, however, there was evidence from multiple investigations that the intervention programs examined led to increases in knowledge, positive changes in attitudes linked to retirement, and an increase in retirement-linked planning and preparation behaviors. Identification of strengths and weaknesses in the methods used and efficacy of these interventions could facilitate the construction of a research agenda aimed at promoting more favorable research designs. Use of more rigorous designs would stand to improve the internal validity of these retirement programs and, consequently, progress in this field. 相似文献
