This study describes and analyses the conceptions of primary teachers and secondary teachers of Physics–Chemistry, Biology–Geology and Geography–History with respect to the concept of heritage and its teaching and learning, taking the model of teacher-researcher as the theoretical referent. The data collection instrument used was a questionnaire, designed on the basis of categories that in turn were used for the analysis of the resulting data. The results show a high degree of homogeneity in pedagogic content knowledge, in contrast to the heterogeneity of the conceptions with respect to purely content knowledge.  相似文献

In many countries around the world, there has been an increasing emphasis on improving science education. Recent reform efforts in the USA call for teachers to integrate scientific and engineering practices into science teaching; for example, science teachers are asked to provide learning experiences for students that apply crosscutting concepts (e.g., patterns, scale) and increase understanding of disciplinary core ideas (e.g., physical science, earth science). Engineering practices and engineering design are essential elements of this new vision of science teaching and learning. This paper presents a research study that evaluates the effects of an engineering design-based science curriculum on student learning and attitudes. Three middle school life science teachers and 275 seventh grade students participated in the study. Content assessments and attitude surveys were administered before and after the implementation of the curriculum unit. Statewide mathematics test proficiency scores were included in the data analysis as well. Results provide evidence of the positive effects of implementing the engineering design-based science unit on student attitudes and learning.  相似文献

This study is focused on the relationship between the development of segmental awareness and dyslexia. More specifically we have tried to address the question, is it possible to learn to segment well and yet continue to read and write poorly? For this purpose, 14 second and third grade dyslexic children were assigned to three different training programs. Those who participated in the first two programs were taught the skills required to use the phonemes, while those in the third program, who served as a pseudo-control group, were given the exercises in perceptual and psychomotor activities. After the training program, children who had received the first two training programs reached a level of performance similar to that of normal readers in different tasks of segmentation of phonemes. The improvements observed in these tasks were correlated in dictation but not in reading, where there was no difference after training.  相似文献

QuickChange mutagenesis is the method of choice for site-directed mutagenesis (SDM) of target sequences in a plasmid. It can be applied successfully to small plasmids (up to 10 kb). However, this method cannot efficiently mutate bigger plasmids. Using KOD Hot Start polymerase in combination with high performance liquid chromatography (HPLC) purified primers, we were able to achieve SDM in big plasmids (up to 16 kb) involving not only a single base change but also multiple base changes. Moreover, only six polymerase chain reaction (PCR) cycles and 0.5 μl of polymerase (instead of 18 PCR cycles and 1.0 μl of enzyme in the standard protocol) were sufficient for the reaction.  相似文献

This article investigates legal and political issues as they relate to school vouchers serving students of color. Specifically, we draw on the empirical, historical, and legal research to examine whether school vouchers will create a more equitable system of education for poor students of color. First, we present a history of vouchers, including how they were used to support segregation. We then discuss how vouchers as a broad opportunity for educational equity for poor children (of color) might present particular challenges in light of, first, the race-neutral approach in contemporary case law and state statutes and, second, the relatively small percentage of U.S. children taking advantage of such programs. Finally, we present empirical results regarding African American families’ support and use of vouchers and a discussion of the racial politics of school vouchers. We argue that unless voucher programs and proponents address race directly, operate on a larger scale, and attend to the broader social justice issues facing urban communities, it will be difficult for such policies to support the greater good for African American children or society as a whole.  相似文献

The phenomenon of women engaging in entrepreneurship is expanding and becoming acknowledged as a valuable resource that must be institutionally and socially supported. Through entrepreneurship education, female students, as potential entrepreneurs, can develop and strengthen those skills and behaviours identified as characteristic of successful entrepreneurs. This paper explores four attributes associated with entrepreneurship (creativity, problem management, risk management, and self-confidence) of 1838 undergraduate students from 11 universities in Latin America (Mexico, Argentina, Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, and Uruguay) and one in Spain, used as a control group. By comparing the results for the male and female student population, self-confidence appears as an attribute that is present at the same level in both groups; statistically significant differences were reported for the other three attributes (creativity, problem management, and risk management). Entrepreneurship programmes can utilise such information to strengthen in female students those attributes for successful engagement in entrepreneurial activity.  相似文献

The widespread adoption of computers and Internet in our life has reached the classrooms, where computer-supported collaborative learning (CSCL) based on wikis offers new ways of collaboration and encourages student participation. When the number of contributions from students increases, traditional assessment procedures of e-learning settings suffer from scalability problems. In a wiki-based learning experience, automatic tools are required to support the assessment of such huge amounts of data. In this work, we present StatMediaWiki, a tool that collects and aggregates information that helps to analyze a MediaWiki installation. It generates charts, tables and different statistics enabling easy analysis of wiki evolution. We have used StatMediaWiki in a Higher Education course and present the results obtained in this case study.  相似文献

Over the last years great efforts have been made within the University environment to implement e-learning technologies in the standard educational practice. These learning technologies distribute online educational multimedia contents through technological platforms. Even though specific e-learning tools for technical disciplines were already available on the Internet, in our opinion more general tools, typically involving calculations, plots or diagrams, through the use of spreadsheets or graphical applications, were still needed to provide a more flexible and multi-purpose integrated environment. Therefore, we developed an integrated system to supply e-learning platforms with almost the same functionalities offered by standalone Office Automation applications. Modular object-oriented dynamic learning environment (MOODLE) and OpenOffice.org were selected to deal with any problem originating from the software and to smooth over the users' learning curve. Furthermore, MOODLE is a modular platform and offers an extensive application programming interface for coding in a simple and effective manner. The implementation of the work required the employment of Java and Asynchronous JavaScript and Extensible Markup Language technologies and included the creation of a Java Applet to be embedded in the web pages of the new MOODLE modules. Students could thus be offered a single working environment for handling “traditional” material and performing practical activities. The students' feedback on this new integrated system was very positive and proved the effectiveness of our work.  相似文献
