Playful and mindful interactions in the recursive adaptations of the zone of proximal development: a critical complexity science approach     

Federica Raia  Mario C. Deng 《Cultural Studies of Science Education》2011,6(4):903-914

We discuss Konstantinos Alexakos, Jayson Jones and Victor Rodriguez’s hermeneutic study of formation and function of kinship-like relationships among inner city male students of color in a college physics classroom. From our Critical Complexity Science framework we first discuss the reading erlebnisse of students laughing at and with each other as something that immediately captured our attention in being transformative of the classroom. We continue by exploring their classroom and research experience as an emergent structure modifying their collective as well as their individual experiences. As we analyze both the classroom and the research space as a complex system, we reflect on the instructor/students interactions characterized by an asymmetrical “power” relationship. From our analysis we propose to consider the zone of proximal development as the constantly emerging and transforming person experience (erlebnisse and erfahrung).  相似文献

Harmonization of pre-analytical quality indicators     

Mario Plebani  Laura Sciacovelli  Ada Aita  Maria Laura Chiozza 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2014,24(1):105-113

Quality indicators (QIs) measure the extent to which set targets are attained and provide a quantitative basis for achieving improvement in care and, in particular, laboratory services. A body of evidence collected in recent years has demonstrated that most errors fall outside the analytical phase, while the pre- and post-analytical steps have been found to be more vulnerable to the risk of error. However, the current lack of attention to extra-laboratory factors and related QIs prevent clinical laboratories from effectively improving total quality and reducing errors. Errors in the pre-analytical phase, which account for 50% to 75% of all laboratory errors, have long been included in the ‘identification and sample problems’ category. However, according to the International Standard for medical laboratory accreditation and a patient-centered view, some additional QIs are needed. In particular, there is a need to measure the appropriateness of all test request and request forms, as well as the quality of sample transportation. The QIs model developed by a working group of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) is a valuable starting point for promoting the harmonization of available QIs, but further efforts should be made to achieve a consensus on the road map for harmonization.  相似文献

A comparison of the perceptions of Love, Anger, and Guilt in Portugal and the United States and implications for counseling     

Rui Paixo  Rui Arago Oliveira  Richard C. Page  Chinw J. Uwah  Jodi L. Carlton 《Int J Intercult Relat》2001,25(6):237

This study compared the ways that graduate and undergraduate counseling and psychology students from Portugal and the United States evaluated the feelings of Love, Anger and Guilt. Utilizing a semantic differential, a multivariate analysis of variance was employed in which the independent variables were Country and Gender and the dependent variables were the evaluative and potency scales of Love, Anger and Guilt. There was no significant main effect for gender and there was no significant interaction effect for gender by country. There was a significant main effect for country. It was found that students from the United States evaluated Anger more positively than the Portuguese students and that the Portuguese students evaluated Guilt more positively than the United States students. These findings have implications that are relevant to the counseling process.  相似文献   

Enhancing students’ mathematical reasoning in the classroom: teacher actions facilitating generalization and justification     

Joana Mata-Pereira  João-Pedro da Ponte 《Educational Studies in Mathematics》2017,96(2):169-186

A proof is a connected sequence of assertions that includes a set of accepted statements, forms of reasoning and modes of representing arguments. Assuming reasoning to be central to proving and aiming to develop knowledge about how teacher actions may promote students’ mathematical reasoning, we conduct design research where whole-class mathematical discussions triggered by exploratory tasks play a key role. We take mathematical reasoning as making justified inferences and we consider generalizing and justifying central reasoning processes. Regarding teacher actions, we consider inviting, informing/suggesting, supporting/guiding and challenging actions can be identified in whole-class discussions. This paper presents design principles for an intervention geared to tackle such reasoning processes and focuses on a whole-class discussion on a grade 7 lesson about linear equations and functions. Data analysis concerns teacher actions in relation to design principles and to the sought mathematical reasoning processes. The conclusions highlight teacher actions that lead students to generalize and justify. Generalizations may arise from a central challenging action or from several guiding actions. Regarding justifications, a main challenging action seems to be essential, while follow-up guiding actions may promote a further development of this reasoning process. Thus, this paper provides a set of design principles and a characterization of teacher actions which enhance students’ mathematical reasoning processes such as generalization and justification.  相似文献   

The dynamics of connecting universities,non-governmental organizations and community members by means of academic projects directed at people in need     

João Alberto Arantes do Amaral  Cristina Toshie Motohashi Matsusaki 《Educational Action Research》2017,25(2):280-299

In this article we discuss an action research experience that took place from 2002 to 2015. We analyze the inception and progress of several project-based learning-centered academic courses that were aimed at developing the project management skills of graduate and undergraduate students. The experience involved approximately 1800 students from two universities and 40 community partners. The students developed real-life projects on behalf of institutions and non-governmental organizations located in the area that help people in need; we refer to these agencies as ‘community partners.’ We analyze the development of the course from a systemic perspective, making use of causal loop diagrams in order to understand the main driving dynamics. We discuss the results achieved by these projects and the benefits brought to the community partners. We also present testimony from the community partners themselves. We conclude by presenting the lessons we learned over the years we have been running this course.  相似文献   

School principals’ views of teacher evaluation policy: lessons learned from two empirical studies     

Maria Assunção Flores  Mary Lynne Derrington 《International Journal of Leadership in Education》2017,20(4):416-431

Teacher evaluation accountability policies are emerging worldwide. This study examines principals’ perceptions of teacher evaluation in terms of commonalities and differences arising from two research projects conducted in Portugal and in the US. Perceptions of school principals in regard to a new policy on teacher evaluation as well as its perceived effects at school and conditions for its implementation will be analysed. Findings point to the challenges and successes of coping with mandated accountability measures in two different contexts. Principals balanced perceived conflicting goals, sought maintenance of positive teacher relationships and school culture and managed the tensions of policy implementation and the making sense of its effects at school. Implications of the findings are discussed.  相似文献   

Honey-bee mating optimization (HBMO) algorithm for optimal reservoir operation   总被引：2，自引：0，他引：2  

A. Afshar  M.A. Mariño  B.J. Adams 《Journal of The Franklin Institute》2007,344(5):452-462

In recent years, evolutionary and meta-heuristic algorithms have been extensively used as search and optimization tools in various problem domains, including science, commerce, and engineering. Ease of use, broad applicability, and global perspective may be considered as the primary reason for their success. The honey-bee mating process has been considered as a typical swarm-based approach to optimization, in which the search algorithm is inspired by the process of real honey-bee mating. In this paper, the honey-bee mating optimization (HBMO) algorithm is presented and tested with a nonlinear, continuous constrained problem with continuous decision and state variables to demonstrate the efficiency of the algorithm in handling the single reservoir operation optimization problems. It is shown that the performance of the model is quite comparable with the results of the well-developed traditional linear programming (LP) solvers such as LINGO 8.0. Results obtained are quite promising and compare well with the final results of the other approach.  相似文献
