TACTICS (French and Spanish acronym standing for Collaborative Work and Learning in Science with Information and Communications Technologies) is an ongoing project aimed at investigating a distributed community of learning and practice in which information and communications technologies (ICT) take the role of collaborative tools to support social construction of knowledge. This community is composed of researchers, graduate students, and high-school teachers and their students, from six schools and four universities in Canada and Mexico. It set out in fall 2000 to develop a community around the general topic of integrating concepts in science school subjects. Once a prototype community is established, it can become a terrain where different aspects could be studied. Subsequently, researchers could gradually take a back seat allowing as well as ensuring the autonomy of the school members involved and, thereby, the viability of the learning community. The set up of the proposed prototype distributed science learning community was therefore an essential yet far from trivial first step. This paper discusses the process of setting up the community and the lessons learned.  相似文献   

Preschool Teachers' Perceptions about Conflict Resolution, Autonomy, and the Group in Four Countries: United States, Colombia, El Salvador, and Taiwan     

Melanie Killen  Alicia Ardila-Rey  Marlene Barakkatz  Pei-Lin Wang 《Early education and development》2000,11(1):73-92

Preschool teachers (N = 160) in four countries (U.S., Colombia, El Salvador, and Taiwan) were surveyed about their views of conflict resolutions for moral and social-conventional conflicts, providing choice in the classroom (autonomy), maintaining a sense of the group, and general pedagogical aims of early childhood education. The findings revealed cultural similarities regarding conflict resolution intervention techniques and providing choice in the classroom. Cultural differences were found for maintaining the group and encouraging traditional group values. The items regarding the general pedagogical aims revealed a mixture of cultural differences and similarities. The results have implications for formulating generalizable goals for facilitating social and moral development in early childhood development and education.  相似文献

Class-first analysis in a continuum: an approach to the complexities of schools, society, and insurgent science     

Laura Alicia Valdiviezo 《Cultural Studies of Science Education》2010,5(2):435-445

This essay addresses Katherine Richardson Bruna’s paper: Mexican Immigrant Transnational Social Capital and Class Transformation: Examining the Role of Peer Mediation in Insurgent Science, through five main points. First, I offer a comparison between the traditional analysis of classism in Latin America and Richardson Bruna’s call for a class-first analysis in the North American social sciences where there has been a tendency to obviate the specific examination of class relations and class issues. Secondly, I discuss that a class-first analysis solely cannot suffice to depict the complex dimensions in the relations of schools and society. Thus, I suggest a continuum in the class-first analysis. Third, I argue that social constructions surrounding issues of language, ethnicity, and gender necessarily intersect with issues of class and that, in fact, those other constructions offer compatible epistemologies that aid in representing the complexity of social and institutional practices in the capitalist society. Richardson Bruna’s analysis of Augusto’s interactions with his teacher and peers in the science class provides a fourth point of discussion in this essay. As a final point in my response I discuss Richardson Bruna’s idea of making accessible class-first analysis knowledge to educators and especially to science teachers.  相似文献   

ESD and lifelong learning: a case study of the Shangri-la Institute’s current engagement with the Bazhu community in Diqing, China     

Yunhua Liu  Alicia Constable 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2010,9(3):271-285

This article argues that ESD should be integrated into lifelong learning and provides an example of how this might be done. It draws on a case study of a joint project between the Shangri-la Institute and the Bazhu community in Diqing, southwest China, to analyse a community-based approach to Education for Sustainable Development and assess its implications for lifelong learning. The article examines the different knowledge, skills and values needed for ESD across the life span and asserts the need for these competencies to be informed by the local context. The importance of linking ESD with local culture and indigenous knowledge is emphasised. The article goes on to propose methods for integrating ESD into lifelong learning and underscore the need for learning at the individual, institutional and societal levels in formal, non-formal and informal learning settings. It calls for institutional changes that link formal, non-formal and informal learning through the common theme of ESD, and establish platforms to share experiences, reflect on these and thereby continually improve ESD.  相似文献   

The Impact of an Obstacle Course Sport Education Season on Students' Aerobic Fitness Levels     

Peter A. Hastie  Alice M. Buchanan  Danielle D. Wadsworth  Brandon J. Sluder 《Research quarterly for exercise and sport》2013,84(4):788-791

Abstract

The purpose of this study was to determine if factor patterns of selected sports skills were similar for two samples, a skilled sample and one consisting of a wide range of skills. Comparisons were also made with kinesiological evidence regarding the patterning of basic sports skills. Data consisting of performance scores on various sports skills were available for 166 high school girls. Out of this sample, a smaller sample was drawn consisting of 69 girls who were above average in skill. Two factor models, alpha and incomplete image analysis, were used in the analysis of this data. The factor pattern of selected sports skills performed by subjects above average in skill was similar in many respects to that of a sample which included a wide range of skill. The primary difference lay in the clustering of overarm skills which appeared in the above-average factor pattern. The overarm and push patterns of the above-average sample resembled the patterns of skill obtained through kinesiological analysis. The structure of kicking, underarm, and sidearm skills remained obscure, based on the results of factor analytic techniques.  相似文献   

The Concept of Tens and Hundreds in Students with Down Syndrome     

Alicia Bruno  Aurelia Noda 《International Journal of Disability, Development & Education》2019,66(2):171-185

ABSTRACT

We present an evaluation of the understanding that adolescents and adults with Down syndrome (DS) have of the decimal number system. The results of two studies are presented. The first was a case study with interviews of three adolescents and three adults with Down syndrome. Our results indicate that their conceptual understanding of the meaning of the tens and hundreds places is not as well developed as their ability to read, write and work with numbers of up to three digits. We also analyse the progress made by a 17- year-old student with Down syndrome after following a learning programme intended to improve her understanding of the tens place. To this end, we designed number tasks using four constructs: counting, grouping, partitioning and ordering. The student’s achievements in the counting construct were greater than in the others, exhibiting an understanding and use of the tens as a unit of counting to solve many of the number tasks proposed. Also evident was a progression in her understanding of the positional value. We observed differences in her success rate and variability in her responses depending on the method used in the tasks to represent the numbers.  相似文献   

Student Drivers and the Fiduciary Duty of School Boards     

James Kent Donlevy  Dianne Gereluk  Jim Brandon  Peggy Patterson 《Interchange》2017,48(2):195-203

Following E.D.G. v. Hammer, Canadian law has held that school boards, although they have a fiduciary duty to their students, do not guarantee the safety of their students from the acts of their employees. The scope of that fiduciary duty is narrow, restricted to a board acting with disloyalty, in bad faith, or in a conflict of interest to its students, which causes them injury. This paper takes the position that the scope of that duty should include cases where a school board’s policy allows students to use their own cars to drive fellow students to school-sponsored functions.  相似文献   

The Effect of Loans on the Persistence and Attainment of Community College Students   总被引：1，自引：0，他引：1  

Alicia C. Dowd  Tarek Coury 《Research in higher education》2006,47(1):33-62

This study informs public policies regarding the use of subsidized loans as financial aid for community college students. Using logistic regression, it analyzes the National Center for Education Statistics’ Beginning Postsecondary Students (BPS 90/94) data to predict persistence to the second year of college and associate’s degree attainment over five years. During the period under study, loans did not contribute to higher persistence and attainment rates. Loans are observed to have a negative effect on persistence and no effect on degree attainment. Estimates of the interaction effects of borrowing and income status are insignificant but demonstrate the need for further testing. The findings are attributed to a combination of the high uncertainty of degree completion among community college students and the negative affective component of indebtedness. Earlier versions of this paper were presented at the American Education Finance Association Annual Meeting (Austin, Texas, March, 2000) and at the AIR Forum (Cincinnati, Ohio, May 2000). It has also appeared as a working paper of the Institute for Higher Education Law and Governance at the University of Houston, Texas (IHELG Monograph 01–07).This paper is based upon work supported by the Association for Institutional Research, the National Center for Education Statistics and the National Science Foundation under Association for Institutional Research Grant No. 99-128-0.  相似文献   

Pedagogical content knowledge as reflected in teacher–student interactions: Analysis of two video cases     

Alicia C. Alonzo  Mareike Kobarg  Tina Seidel 《科学教学研究杂志》2012,49(10):1211-1239

Despite the theorized centrality of pedagogical content knowledge (PCK) for teaching, we have little evidence of the relationship between PCK and students' learning and know relatively little about how to help teachers to develop PCK. This study is a preliminary attempt to address these gaps in our knowledge of PCK through exploration of two German physics teachers' classroom instruction in consecutive lessons on optics. We show how video analysis can be used to gather evidence for one aspect of teachers' PCK: their use of content knowledge in interactions with students. We identify three potentially important characteristics of this aspect of PCK: flexibility, richness, and learner‐centeredness. By contrasting teachers with high and low gains in student knowledge and interest, we explore potential mechanisms by which this aspect of PCK might affect student outcomes. Because German teacher preparation programs emphasize content more than pedagogical knowledge, these cases contribute to our understanding of the support that teachers with strong content knowledge may need in translating this knowledge into a form useful for teaching.Fachdidaktisches Wissen ist aus theoretischer Sicht besonders zentral für das Unterrichten. Aus empirischer Sicht gibt es bislang allerdings noch wenig Evidenz für den Einsatz fachdidaktischen Wissens während des Unterrichtens und seine Bedeutung für das Lernen von Schülerinnen und Schülern. Außerdem wissen wir wenig darüber, wie Lehrpersonen über die Zeit fachdidaktisches Wissen entwickeln. Diese Studie ist ein Versuch, diese Wissenslücken zum fachdidaktischen Wissen von Lehrpersonen zu bearbeiten. Dabei wird exemplarisch der Unterricht von zwei deutschen Physiklehrern in aufeinanderfolgenden Stunden zum Thema Optik untersucht. Die Studie zeigt wie Videoanalysen genutzt werden können, um Belege für einen Aspekt des fachdidaktischen Wissens der Lehrpersonen zu sammeln: Ihre Nutzung von inhaltlichem Wissen in der Interaktion mit den Schülerinnen und Schülern. In dieser Studie werden drei potentiell wichtige Charakteristika dieses Aspekts des fachdidaktischen Wissens identifiziert: Flexibilität, Reichhaltigkeit und Schülerorientierung. Durch die Gegenüberstellung von Lehrpersonen mit hohem und niedrigem Wissens‐ und Interessenzuwachs wurden potentielle Mechanismen untersucht, durch die dieser Aspekt des fachdidaktischen Wissens die Lernergebnisse von Schülerinnen und Schülern beeinflussen kann. Die Lehrerausbildung in Deutschland betont das inhaltliche Wissen stärker als das fachdidaktische Wissen. Die ausgewählten Fälle beschreiben, welche Unterstützung Lehrpersonen mit einem hohen fachlichen Wissen benötigen, um dieses Wissen so zu verändern, dass es für das Unterrichten genutzt werden kann. © 2012 Wiley Periodicals, Inc.
