This study examined the impact of computer simulation and supported science learning on a teacher’s understanding and conceptual
knowledge of current electricity. Pre/Post tests were used to measure the teachers’ concept attainment. Overall, there was
a significant and large knowledge difference effect from Pre to Post test. Two interesting interactions were observed during
the data analysis. The first was the difference between Elementary and Secondary teachers. Both groups had significant gains,
with large effect sizes, but the Elementary teachers (Pre-Mean = 3.70, Post-Mean = 7.51) started lower and ended higher exhibiting
a significantly larger gain than the Secondary teachers (Pre-Mean = 4.96, Post-Mean = 6.71). The second interaction was the
impact of gender. Both groups showed significant gains, with large effect sizes, but females (Pre-Mean = 3.90, Post-Mean = 7.21)
gained significantly more than males (Pre-Mean = 5.13, Post-Mean = 7.01). These results confirm that computer simulation supported
science learning can have a positive effect on concept attainment in teachers. 相似文献

Drawing on their experience in a Midwest healthcare system, the authors propose a model of leadership development through action learning that embraces ‘concentric collaboration’ at its core. The present study suggests that the process of concentric collaboration can serve to strengthen the skills of the individual leader as well as foster collective leadership. Central to the model is the growth and development of the individual leader which extends outward to create connections with others, ultimately increasing the social capital necessary to effect organizational change. This work contributes to the leadership development literature by offering a comprehensive model that includes the process of individual growth as well as collective capacity, organizational factors that support or inhibit this process as well as implications for practice. 相似文献

Mapping the curriculum of a professional degree to the associated competency standard ensures graduates have the competence to perform as professionals. Existing approaches to competence mapping vary greatly in depth, complexity, and effectiveness, and a standardised approach remains elusive. This paper describes a new mapping software tool that streamlines and standardises the competency mapping process. The available analytics facilitate ongoing programme review, management, and accreditation. The complete mapping and analysis of an Australian mechanical engineering degree programme is described as a case study. Each subject is mapped by evaluating the amount and depth of competence development present. Combining subject results then enables highly detailed programme level analysis. The mapping process is designed to be administratively light, with aspects of professional development embedded in the software. The effective competence mapping described in this paper enables quantification of learning within a professional degree programme, and provides a mechanism for holistic programme improvement. 相似文献

This paper analyses pre-service education student perceptions and perspectives related to education for democracy in Australia. Using a critical pedagogical framework datum from an online survey, it presents both quantitative and qualitative responses of contrasting understandings of democracy. It begins by outlining the concepts of thick and thin democracy and why this is important in relation to contemporary debates about the state of civics and citizenship education, and then explains the conceptual framework of critical pedagogy and methodology. The datum analysed is discussed in relation to neoliberalism and indicates that the pre-service teachers in this study view democracy in a narrow or thin way that may impact on their classroom practice where they would be teaching about but not for democracy. A more critical and thicker understanding of democracy is suggested as essential if we desire our students to become active and transformative citizens. 相似文献

We examined the implementation of a laser-disk based science curriculum in an elementary school. The goal was to develop a richer understanding of the principles for designing a curriculum that will adequately support teachers in adopting a learner-centered framework. Issues included: who has ownership of the classroom discussion; what types of activities are engaged in terms of the constraints imposed; and what is the teacher's response to the specific tools provided (the teacher's guide, the Circle of Learning, and concept maps). In addition to looking at the implementation pattern, we also examined the impact of the implementation on student attitudes and anxiety toward science. Results indicated little adoption of the curriculum, and teachers continued to maintain a high degree of control in the classroom. However, results also indicated significant effects of the curriculum on science attitude and anxiety. Suggestions for future research are included. 相似文献

A study of students from a primary school and its local secondary school was conducted to investigate students' relative interests
in geology and biology during the years prior to Year 10. Students from Years 1, 3, 5, 7 and 9 were interviewed, using an
innovative interview technique, and results show that interest in both subjects appears to be fairly evenly distributed throughout
all years. This paper reports on the study conducted and illustrates the success of the interview technique developed to accommodate
all students, especially those from younger year levels.

Elderly people are exposed to information technologies to keep them in touch with younger generations. Among various technologies, social network sites (SNSs) are seldom used by the majority of elderly people. To bridge the digital divide, it is necessary to dig deeply into the minority elderly users of SNSs. This study explores usage patterns of elderly Facebook users and further investigates how their diverse characteristics influence their usage and social circles. Three findings were derived. First, a sharp digital divide on SNSs does exist, and existing elderly Facebook users are mainly the dabblers. Second, personality profiling could predict elderly people’s SNS usage behaviors. Elderly users with a high level of openness and extroversion have more friends, status updates, and group memberships, and those with a high level of conscientiousness have fewer likes and status updates. Elderly users are likely to seek insightful content on SNSs. Moreover, they may have a higher degree of emotional stability than young users when using SNSs. Third, elderly people tend to build small social circles on SNSs that “copy” the family relationship in the real world; whereas, they build large social circles with interests and hobbies that are difficult to share in the real world. Based on these results, detailed suggestions are presented for better targeting elderly people in ways that move them toward SNSs. 相似文献

In human infancy, 2 criteria for intentional communication are (a) persistence in and (b) elaboration of communication when initial attempts to communicate fail. Twenty-nine chimpanzees (Pan troglodytes) were presented with both desirable (a banana) and undesirable food (commercial primate chow). Three conditions were administered: (a) the banana was delivered (successful communication), (b) half of the banana was delivered (partially successful communication), and (c) the chow was delivered (failed communication). The chimpanzees exhibited persistence in and elaboration of their communication in every condition except when the banana was delivered. Thus, their communication was about a specific item, demonstrating that both intentionality and nonverbal reference are capacities shared by humans with our nearest living relatives, the great apes. 相似文献
