Investigating science teachers’ classroom discourse and students’ reasoning quality through argument-based inquiry approach.

İnal, Gülşah Özka
This study had three purposes, first the science teachers’ discursive moves (TDMs) during classroom discourse in medium and high levels of Argument Based Inquiry (ABI) implementation were investigated. Moreover, the relationship between the TDMs and their students’ reasoning qualities was also explored in different levels. Finally, this study investigated types of communicative approach performed by teachers. The participants of this study were two elementary science teachers who were selected purposefully among teachers who attended the professional development (PD) program. These teachers’ students were also involved in this study. The data source of this study was video recordings of ABI implementations. The data were analyzed with the systematic observation. The results of the current study revealed that both teachers conducted reflective discourse more and provided knowledge and evaluated students’ response less in high levels of ABI implementation. However, they had difficulty in performing some discursive moves (challenging and seeking for evidence) in both levels. The changes in the percentages of TDMs (knowledge providing and evaluating, reflective discourse) were related to increasing students’ reasoning qualities because their reasoning qualities were more sophisticated in high level. Finally, the teachers considered students’ different points of view more frequently by performing more dialogic approach in high level. Although students were given more opportunity to offer different points of view in high level, students had still difficulty in using evidence and rule-based reasoning while supporting their claim. Then, the recommendations for PD program are given about how teachers create classroom discourse for increasing students’ reasoning quality.


Developing preservice science teachers’ socioscientific reasoning through socioscientific issues-focused course
Cansız, Nurcan; Yılmaz Tüzün, Özgül; Sadler, Troy D.; Department of Elementary Education (2014)
The purpose of this study was to investigate how preservice science teachers’ (PSTs) socioscientific reasoning changes in response to participation in a socioscientific issues-focused course. Socioscientific issues (SSI) are complex, uncertain, lack clear-cut solutions; require ongoing research and examining from multiple perspectives. Individuals should recognize the complexities associated with SSI, examine them from multiple perspectives and, appreciate the need for ongoing inquiry to negotiate and resol...
Promoting Conceptual Understanding with Explicit Epistemic Intervention in Metacognitive Instruction: Interaction Between the Treatment and Epistemic Cognition
Yerdelen-Damar, Sevda; Eryılmaz, Ali (2021-04-01)
This study investigated the effect of the metacognitive instruction in which students’ epistemic cognitions were explicitly addressed, on tenth-grade students’ conceptual understandings regarding force and motion. The participants of the study included 107 (49 female, 58 male) tenth-grade students at two public high schools. A quasi-experimental design was employed. Two intact classes of each school were randomly assigned to the experimental and control groups. The Force and Motion Conceptual Tests I and II...
Yılmaz, Nursel; ALICI, ŞULE (2011-07-01)
The purpose of this study was to investigate pre-service early childhood teachers' attitudes towards using Computer Based Education (CBE) while implementing science activities. More specifically, the present study examined the effect of different variables such as gender, year in program, experience in preschool, owing a computer, and the frequency of computer usage on pre-service early childhood teachers' attitudes towards using CBE while implementing science activities. The study was conducted by survey m...
Investigating pre-service science teachers’ understandings and use of models
Yenilmez Türkoğlu, Ayşe; Öztekin, Ceren; Department of Elementary Education (2013)
To gain a better understanding of pre-service science teachers’ (PSTs’) views of models, a case study was conducted with fourteen PSTs in a large public university in Ankara. The study aims to provide an answer to the research question, ‘What understandings do PSTs possess about scientific models and the models used in science education?’ and to explore how they use these models in their classroom practices. Data were collected using an open-item instrument, semi-structured interviews, class observations, a...
Analysis of pre-service science teachers’ systems thinking skills in the context of carbon cycle
Turan, Deniz; Öztekin, Ceren; Department of Elementary Science and Mathematics Education (2019)
The main purpose of this study is to analyze pre-service science teachers’ systems thinking skills in the context of carbon cycle. The eight systems thinking skills that is previously defined by Ben-Zvi Assaraf and Orion (2005) were used to investigate the participants’ systems thinking skills concerning the carbon cycle. Data was collected from four senior-year pre-service science teachers from elementary science education department of a state university. The data obtained through word association test, c...
