ABSTRACT

Carrying out effective and efficient research on Mexican law presents special challenges. Some of these are structural because they condition the entire research process. This guide covers all aspects of Mexican legal research, providing a contextualized overview of the subject. The guide is organized into three main sections: Primary Sources, Secondary Sources, and Online Resources. The reader of this guide will gain a solid foundation in how to do research on Mexican law.  相似文献

Metric scale is an important concept taught as part of science curricula across different countries. This study explored metric and relative (body-length) scale concepts of inservice (N?=?92) and preservice (N?=?134) teachers from Austria, and Taiwan, and their concepts were compared with those of teachers from the USA. Participants completed three assessments: the Scale Anchoring Objects (SAO), Scale of Objects Questionnaire (SOQ), and a subsample of participants were interviewed with the Learning Scale Interview. A Rasch analysis was conducted with the SAO and SOQ and results showed that the Rasch model held for these assessments, indicating that there is an underlying common dimension to understanding scale. Further analyses showed that accuracy of knowledge of scale measured by the SAO and SOQ was not related to professional experience. There were significant differences in teachers’ accuracy of scale concepts by nationality. This was true for both metric and body-length SAO assessments. Post hoc comparisons showed that the Austrian and Taiwanese participants were significantly more accurate than the US sample on the SAO and SOQ. The Austrian participants scored significantly higher than the US and the Taiwanese participants. The results of the interviews showed that the Taiwanese experienced teacher participants were more likely to report learning size and scale through in-school experiences than the Austrian or the US participants. US teachers reported learning size and scale most often through participating in hobbies and sports, Taiwanese teachers reported learning scale through sports and reading, and Austrian teachers most often noted that they learned about scale through travel.  相似文献

The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something‐because it is always before one's eyes.). . .And this means: we fail to be struck by what, once seen, is most striking and most powerful.

Thirty-four seven-year-old children who could not coordinate perspectives were divided randomly into your groups. The first group underwent a teacher-directed training sequence based on factors identified by Piaget and Inhelder. The second group received an automated training program in sighting, based on points, line segments, and line segment extensions. The third group received a combination of the two programs; the fourth served as a control group. Posttests revealed overall gain among the subjects. The improvement was differential, however, and involved an interaction of method, and sex of the subject. Further analyses indicated non-significant differences among the girls, but among the boys the teacher-directed program was superior at the 05 level. The combination program closely approached statistical significance, while the automated program resulted in some loss of ability to coordinate perspectives.  相似文献

Abstract

This study investigated the effects of instruction in environmental education on the attitudes of elementary school children toward the environment. One class of third graders was provided with two hours of environmental education instruction. A comparable class of third graders served as a control group. Both classes were pre- and posttested using an author-designed environmental attitude questionnaire. Analyses of these data showed that 1) the experimental group had significantly improved attitudes on a pre-post basis and 2) this same group had significantly more positive attitudes toward the environment when compared with the control group. When tested again as fifth graders, the experimental group remained significantly more positive toward the environment than the fifth grade control group.  相似文献

Student achievement of the curriculum is the school's reason for being. This research, however, suggests that the behavior of school leaders is not effective in accomplishing four critical outcomes of curriculum development: (1) the creation of well-written documents that use a common framework; (2) curriculum that is aligned with state and national standards; (3) an understanding and teaching of the curriculum by teachers; and (4) all students successfully learning the curriculum. Leaders must orchestrate multiple changes that provide opportunities for teachers to work in teams, focus resources effectively on implementing the curriculum, and establish accountability for results.  相似文献

The museum in the contemporary era imports from the nineteenth century a venerable idea: that the first responsibility of a public art museum is to enlighten and improve its visitors, morally, socially, and politically. Yet visitors often seem to have arrived from another planet, bringing with them their own cultural meanings and agendas. A series of two articles presents ethnographic data, anthropological analysis, and a marketing perspective to suggest why the visitors' points of view may seem vertiginously strange to museum personnel. This article, Part One, characterizes the conflict between host and guest as the outcome of two competing models of culture: “preferment” and “transformation.” In a subsequent issue of Curator, Part Two will examine the influence of consumer culture on these models, and offer strategies for rapprochement.  相似文献

The appropriate determination of performance outcome is critical when appraising a performer’s technique. Previous studies of rugby place kicking technique have typically assessed performance based on ball velocity, but this is not the sole requirement. Therefore, a mathematical model of rugby place kick ball flight was developed to yield a single measure more representative of true performance. The model, which requires only initial ball flight kinematics, was calibrated and validated using empirical place kick data, and found to predict ball position with a mean error of 4.0% after 22 m of ball flight. The model was then applied to the performances of 33 place kickers. The predicted maximum distance, a single performance measure which accounted for initial ball velocity magnitude and direction, and spin, was determined using the model and was compared against ball velocity magnitude. A moderate association in the rank-order of the kicks between these two measures (ρ = 0.52) revealed that the relative success of the kicks would be assessed differently with each measure. The developed model provides a representative measure of place kick performance that is understandable for coaches, and can be used to predict changes in performance outcome under different ball launch or environmental conditions.  相似文献
