Observational narrative knowledging in early professional development of student teachers of English

This paper presents a narrative inquiry approach to understanding the early professional development (PD) of student teachers of English at a state university in Turkey. With the twofold functioning of narrative as a tool for both research and PD, we probe into how student teachers’ early PD trajectories are shaped through observational narrative knowledging. Data consisted of group discussions, semi-structured interviews, metaphor elicitations, and informal conversations that accompanied the main data collection tool, i.e., narrative frames collected during the practicum. The triangulated data were subjected to a multi-tiered collaborative content analysis. The findings showed that narrative-embedded observations helped student teachers organize and attach meaning to their early field experiences, and thus build on their self-awareness, critical thinking, and reflectivity for future classroom practices. We also reported how the participants reflected retrospectively, in the course of, and the posteriori of writing the classroom observational narratives. Through narrative knowledging, we offer a more nuanced approach to aiding student teachers’ early PD.

PROFILE OF NEW TEACHERS IN THE TURKISH EDUCATIONAL SYSTEM     

Galip Karagözoğlu  Karen Bellefleur Murray 《Higher Education in Europe》1988,13(4):27-35

A profile of students entering the teaching profession in Turkey was developed based on demographic and academic information obtained from the University Entrance Examination (UEEX) for 1982 and 1986. Findings reveal that low achieving students and others from low‐income families comprise the majority of persons desiring to become teachers at the elementary and secondary levels, thus posing the possibility of education serving as a vehicle for upward mobility. Alternative are considered so as to alleviate the consequences of the entering of less capable leaders into education than was the case in the past, in Atatürk's time, when educators were held in high esteem.  相似文献   

Design of observer-based feedback control for time-delay systems with application to automotive powertrain control     

Sun Yi  A. Galip Ulsoy 《Journal of The Franklin Institute》2010,347(1):358-376

A new approach for observer-based feedback control of time-delay systems is developed. Time-delays in systems lead to characteristic equations of infinite dimension, making the systems difficult to control with classical control methods. In this paper, a recently developed approach, based on the Lambert W function, is used to address this difficulty by designing an observer-based state feedback controller via assignment of eigenvalues. The designed observer provides estimation of the state, which converges asymptotically to the actual state, and is then used for state feedback control. The feedback controller and the observer take simple linear forms and, thus, are easy to implement when compared to nonlinear methods. This new approach is applied, for illustration, to the control of a diesel engine to achieve improvement in fuel efficiency and reduction in emissions. The simulation results show excellent closed-loop performance.  相似文献   

A new nonautonomous version of Chua's circuit: Experimental observations     

Recai Kiliç  Ö. Galip Saraço?lu 《Journal of The Franklin Institute》2006,343(2):191-203

In this study, a novel nonautonomous version of autonomous Chua's circuit is presented. The proposed nonautonomous version of Chua's circuit was designed by placing a sinusoidal source to the inner structure of the nonlinear resistor, namely, Chua's diode. The circuit's chaotic dynamics have been investigated by PSpice simulations and laboratory experiments.  相似文献
