The purposes of this study were to analyse (a) if “angle-specific” (AS) flexor and extensor torques were different between ACL-reconstructed and uninvolved limbs, (b) the difference in peak torque occurrence angles for concentric and eccentric knee flexor and extensor torques between involved and uninvolved limbs and (c) if AS concentric and eccentric knee flexor and extensor torques are determinants of performance in the “single-leg hop test” (SLHT) and “vertical jump and reach test” (VJRT) in ACL-reconstructed legs. Twenty-seven male ACL-reconstructed volunteers were included in the study. Isokinetic knee muscle strength, SLHT and VJRT were performed 6 months after ACL reconstruction. No difference was found in extremity and knee joint angle interaction for concentric and eccentric flexor and extensor torques (p > 0.05). Peak torque occurrence angles were not different between involved and uninvolved limbs (p > 0.05). In involved extremities, concentric knee extensor strength at 90° was a determinant of SLHT performance (R2 = 0.403, p < 0.05), and concentric knee extensor strength at 60° was a determinant of VJRT (R2 = 0.224, p < 0.05). Assessment of AS concentric knee extensor strength at 60° and 90° might be important, because these were determinants of functional test performance. 相似文献

Nanobiotechnology, which resulted from the convergence of biotechnology and nanotechnology, is a new field of research, and it has an increasing impact on peoples’ everyday lives. Thus, it is important to measure peoples’ attitudes towards nanobiotechnology, in particular, those who are specifically involved in biology and science education. However, despite the existence of an adequate number of instruments on biotechnology or nanotechnology, for nanobiotechnology, there is no instrument that has been rigorously validated. Therefore, the aim of this study was to develop a nanobiotechnology scale for assessing the undergraduate students’ attitudes. The data were gathered from 236 student teachers enrolled in the departments of biology education and elementary science education. The findings from exploratory factor analysis (EFA) provided evidence for the validity and reliability of the final form of the scale. At total of 36 items were identified and contained within the following four factors, nanobiotechnology awareness, interest in nanobiotechnology, nanobiotechnology education, and the applications of nanobiotechnology. The total variance was 53.021%, and the Cronbach’s alpha for the overall scale was 0.93. The scale was later given to 203 student teachers, the results of which were presented in this study. The results indicated significant differences in gender and department in some of the subscales of the scale. As a result, it is believed that the instrument will be a valuable tool for both instructors and researchers in science education to assess the student teachers’ attitudes about nanobiotechnology. 相似文献

Do caregivers in non‐Western communities adapt their behaviors to the needs of infants? This question reflects one of the most long‐standing debates on the universality versus culture‐specificity of caregiver–infant interactions in general and sensitive responsiveness to infants in particular. In this article, an integration of both points of view is presented, based on the theoretical origins of the sensitive responsiveness construct combined with the ethnographic literature on caregivers and infants in different parts of the world. This integration advocates universality without uniformity, and calls for multidisciplinary collaborations to investigate the complexities and nuances of caregiver–infant interactions in different cultures. Salient issues are illustrated with observations of infants (ages 7–31 months) in Mali, the Republic of Congo, and the Philippines. 相似文献

Technological devices are widely used in various forms and for various purposes with educational systems. Teachers are required to not only use technology with the utmost efficiency, but to also act as role models for students in terms of appropriate use of technology. However, many teacher candidates are not aware of the educational use of technology classroom; hence, technology must be especially integrated into undergraduate teacher training programs through courses and field experience. Various methods, techniques, tools, and equipment are utilized in order to improve the efficiency of teaching and learning processes in the classroom, of which digital storytelling is one of them. The use of digital stories in education is beneficial both for teachers and students. For this reason, this research investigates the use of digital stories in mathematics education as well as the opinions and experiences of mathematics teacher candidates about creating, using, and evaluating digital stories. Data of the study were collected via semistructured interviews, transcribed, and content analyzed. The results of the study showed that prospective math teachers preferred GoAnimate program to create digital stories due to its ease of use, design, and the characters and visuals it suggests. Furthermore, the prospective teachers were found to aspire to use digital stories in their future careers. 相似文献

This paper describes a professional development model for developing science teacher leaders that has evolved and been refined through working with 16 high school chemistry and physics teachers in high-needs schools over the past 3 years. The theoretical framework draws upon Goodwin’s notion of professional vision and Dempsey’s four metaphors to inform an understanding of professional identity consistent with innovation and empowerment in (a) the classroom setting with students and (b) with teachers in collegial environments. Thus, leadership practices and purposes are discussed at two distinct levels and contexts, which interact reflexively. Sociolinguistic discourse analysis of multiple data sources enabled us to identify the professional development features that promoted or hindered the teachers’ growth toward a leadership perspective and disposition. Implications for science teacher renewal and retention as well as limitations of the study and proposed leadership model are also shared and discussed. 相似文献

The aim of this study is to explore the research trends in the context of postgraduate programmes in the field of Educational Technology (ET) in Turkey between 1996 and 2016, and to uncover the possible factors that influence these trends from the perspective of ET faculty members. This study was informed by critical theory and employed the critical inquiry method. In the first phase, content analysis technique was used in order to explore trends in research methods and topics in theses completed in ET postgraduate programmes in Turkey. In the second phase, in-depth interviews were conducted with 11 faculty members regarding the possible influential factors. The findings of the content analysis indicated that ET research was dominated by quantitative research designs in the examined theses. Critical methods were overlooked and social, cultural, and political issues were largely silenced. The findings of the interviews showed that the factors that have been influential on ET research trends were the social impact of the research, personal interests and skills, disciplinary and departmental culture, and feasibility concerns. This study presents implications for better ET research by addressing blind spots of the field and providing suggestions for ET postgraduate students, ET scholars, policymakers and practitioners in a global context and other developing countries since the resulting trends in Turkey were found similar to international trends in the field. 相似文献

Physical activity (PA) is important in ensuring a healthy population. It is dependent on various socio-demographic (SD) factors, such as age, gender, employment and marital status. A limited number of studies have investigated the relationship between SD factors and PA but research exploring this relationship from the perspective of gated and non-gated neighbourhoods is scarcer. Therefore, the objective of this study is to investigate the relationship between SD factors and PA variables in gated and nongated neighbourhoods in Karachi Pakistan. Results of the independent sample t-test and Pearson chi-square showed that young and single people do more sports activities in gated neighbourhoods. Women, unemployed people and public transport users walk more in non-gated neighbourhoods. In conclusion, future neighbourhoods should have more pedestrian friendly areas and a larger number of PA facilities, rather than building more walls and gates. 相似文献
