    The Contribution of Constructivist Instruction Accompanied by Concept Mapping in Enhancing Pre-service Chemistry Teachers' Conceptual Understanding of Chemistry in the Laboratory Course
    (SPRINGER, 2009) Aydin, Sevgi; Aydemir, Nurdane; Boz, Yezdan; Cetin-Dindar, Ayla; Bektas, Oktay
    The present study aimed to evaluate whether a chemistry laboratory course called "Laboratory Experiments in Science Education" based on constructivist instruction accompanied with concept mapping enhanced pre-service chemistry teachers' conceptual understanding. Data were collected from five pre-service chemistry teachers at a university in Ankara by means of a concept test and semi-structured interviews. Results showed that pre-service teachers had some alternative conceptions about chemistry topics. Moreover, using constructivist instruction accompanied with concept maps as an instructional tool was effective to promote conceptual understanding. Participants thought that concept maps were useful especially in recognizing the relation between different chemistry concepts.

    Pre-service chemistry teachers' knowledge regarding laboratory equipment and their functions
    (ELSEVIER SCIENCE BV, 2011) Bektas, Oktay; Tuysuz, Mustafa; Kirbulut, Zubeyde Demet; Cetin-Dindar, Ayla
    The purpose of the current study was to investigate pre-service chemistry teachers' knowledge about chemistry laboratory equipments and their functions. The sample of this study consisted of eight pre-service chemistry teachers. Open-ended questions were used in this study. The findings of this study showed that most of the participants mentioned the erlenmeyer and thermometer as laboratory equipments when they were asked to write the equipments that they remembered. Additionally, it was seen that participants had difficulties in explaining the function of the equipments. This study concluded that pre-service chemistry teachers did not identify laboratory equipments and know their functions appropriately. (c) 2011 Published by Elsevier Ltd.

    Prospective chemistry teachers' experiences of teaching practice
    (ELSEVIER SCIENCE BV, 2011) Kirbulut, Zubeyde Demet; Bektas, Oktay
    The purpose of this study is to investigate the prospective chemistry teachers' experiences of teaching practice. This study employed the phenomenological method. Six prospective chemistry teachers enrolled in teaching practice course were selected by intensity sampling. The results indicated that teaching practice course was crucial in prospective teachers' understanding and development of teaching profession. Interviewees said that teaching practice course caused them to be aware of their inadequacies in pedagogical content knowledge and characteristics of a good teacher. The findings of this study concluded that teaching practice is critical period for the prospective teachers in their development as a teacher. (C) 2011 Published by Elsevier Ltd.
