AbstractIn England, both Religious Education (RE) and science are mandatory parts of the school curriculum throughout the 5-16 age range. Nevertheless, there remain concerns that, as in many countries, students do not have a good understanding about the scope of each subject nor about how the two subjects relate. This article reports on a study that involved an intervention of six lessons in RE and six in science that were intended to help 13-15?year-old students develop a better appreciation for the relationship(s) between science and religion and a less reductionist understanding of biology. Our focus here is on the understandings that students have about the relationship between science and religion. The intervention was successful in improving the understandings of almost half of the students interviewed, but in these interviews we still found many instances where students showed misunderstandings of the nature of both religious and scientific knowledge. We argue that RE needs to attend to questions regarding the nature of knowledge if students are to develop better understandings of the scope of religions and how they arrive at their knowledge claims. 相似文献

The recognition and affirmation of student identity in New Zealand primary schools is a policy requirement. While directives for its implementation are found in the current national curriculum, little, if any, guidance is given about what this means or how it might look in classroom programmes. This paper discusses a study concerning the beliefs, understandings and practices of teachers as they interpret the curriculum related to the identity directive. The findings indicate that a marked divergence exists between the identity directive encoded into the curriculum and the way in which teachers decode and enact the directive in their practice. This article argues that two unintended effects are produced as a result of this divergence. First, rather than promote the affirmation of student identity, the enactment of this directive might, in fact, lead to ethnic division. Second, attempts to recognise and affirm identity have led to the displacement of school subject knowledge in classroom programmes. These unintended outcomes are not only unacknowledged, but they continue to disadvantage the community the identity directive was intended to address. 相似文献

Assessing the influence of field- and GIS-based inquiry on student attitude and conceptual knowledge in an undergraduate ecology lab 下载免费PDF全文
Combining field experience with use of information technology has the potential to create a problem-based learning environment that engages learners in authentic scientific inquiry. This study, conducted over a 2-yr period, determined differences in attitudes and conceptual knowledge between students in a field lab and students with combined field and geographic information systems (GIS) experience. All students used radio-telemetry equipment to locate fox squirrels, while one group of students was provided an additional data set in a GIS to visualize and quantify squirrel locations. Pre/postsurveys and tests revealed that attitudes improved in year 1 for both groups of students, but differences were minimal between groups. Attitudes generally declined in year 2 due to a change in the authenticity of the field experience; however, attitudes for students that used GIS declined less than those with field experience only. Conceptual knowledge also increased for both groups in both years. The field-based nature of this lab likely had a greater influence on student attitude and conceptual knowledge than did the use of GIS. Although significant differences were limited, GIS did not negatively impact student attitude or conceptual knowledge but potentially provided other benefits to learners. 相似文献

Abstract The purpose of this transcendental phenomenological study was to describe teacher experiences of teacher-to-student technology-mediated communication (TMC) in secondary virtual school (VS) environments in Alabama. The central research question for this study was: How do virtual school teachers in Alabama describe their experiences of teacher-to-student technology-mediated communication in secondary virtual school environments? Students educated in virtual environments use TMC, so teachers must know what kinds of TMC work best. The problem is that the teacher voice has been ignored in identifying teacher-to-student TMC that is effective in secondary VS environments. Using purposeful sampling of 12 VS teachers in Alabama, this research utilized semi-structured interviews, artifacts, and an asynchronous online focus group to uncover teacher experiences of teacher-to-student interactions in VS environments. In seeking meaning from their experiences, the predominant theme of whatever is best for the students became evident. Four themes developed pertaining to the participants’ experiences: Teacher mindset, teacher presence, integration of technology into instruction, and technology issues. 相似文献

Ten- and 15-day-old rat pups were trained with two procedures to approach an anesthetized mother, and then were punished for approaching. Both ages of subjects exhibited increased latencies to reapproach the mother, indicating passive inhibitions, but only the older pups retreated. All but one of the younger pups eventually reached the mother within 3 min after the punishment, while only half of the older pups did so. In a second experiment examining the development of locomotor avoidance reactions, 5- to 20-day-old rats were shocked without the mother present. Fifteen- and 20-day-old rats significantly decreased their activity patterns in reaction to shock and spent significantly less time in the shock area than either of the younger aged pups. These results suggest that flight reactions are components of a rat’s defensive repertoire that appear very rapidly between 10 and 15 days of age. 相似文献

ABSTRACT Surface compliance has been shown to affect leg stiffness and energetics. It is unknown if compliance differences between common treadmills would elicit such changes. Therefore, the purpose of this study was to determine if compliance design differences of common treadmills would affect the mechanics and energetics of running. Eleven runners ran at moderate, self-selected, matched belt speeds for three minutes on two treadmills: compliant (CT) and rigid (RT) decks. During the last minute of each trial, oxygen consumption and six markers describing the torso, thigh, shank and foot, and one marker to determine treadmill deflection were recorded. Leg stiffness, continuous relative phase (CRP) and CRP variability were calculated. Compared to RT, running on CT resulted in a significantly more compliant leg (8.591 kN?m?1 > 9.063 kN?m?1), lower oxygen consumption (34.69 ml?kg?1?min?1 < 36.86 ml?kg?1?min?1), different coordination patterns and greater variability, particularly during the push-off phase. These results are inconsistent with the literature because the deck of CT rebounds back at the runner during the absorption phase and away from the runner during the push-off phase. Therefore, care should be taken when using treadmills for research and comparing mechanical and energetic measures between studies. 相似文献

This article addresses the issue of bullying and harassment in the United States. The significance of the issue is critical. A historical perspective on the growing attention to and need to confront this social ill is presented. Seminal research related to the topic is interwoven throughout. Practical considerations in addressing the problem are reviewed. Finally, the current state of the bullying epidemic is explored, with implications for the future. 相似文献
