ABSTRACTArgumentation has been a prominent concern in science education research and a common goal in science curriculum in many countries over the past decade. With reference to this goal, policy documents burden responsibilities on science teachers, such as involving students in dialogues and being guides in students’ spoken or written argumentation. Consequently, teachers’ pedagogical practices regarding argumentation gain importance due to their impact on how they incorporate this practice into their classrooms. In this study, therefore, we investigated the instructional strategies adopted by science teachers for their argumentation-based science teaching. Participants were one elementary science teacher, two chemistry teachers, and four graduate students, who have a background in science education. The study took place during a graduate course, which was aimed at developing science teachers’ theory and pedagogy of argumentation. Data sources included the participants’ video-recorded classroom practices, audio-recorded reflections, post-interviews, and participants’ written materials. The findings revealed three typologies of instructional strategies towards argumentation. They are named as Basic Instructional Strategies for Argumentation, Meta-level Instructional ?St??rategies for ?Argumentation, and Meta-strategic Instructional ?St??rategies for ?Argumentation. In conclusion, the study provided a detailed coding framework for the exploration of science teachers’ instructional practices while they are implementing argumentation-based lessons. 相似文献

This study investigated students’ scientific epistemological beliefs in relation to socio-economic status (SES) and gender.
Data were obtained from 1,152 eight grade Turkish elementary school students using Scientific Epistemological Beliefs instrument.
Canonical correlation analysis indicated that students with a working mother and educated parents as well as greater number
of books at home together with a separate study room are more likely to have tentative views and less likely to have fixed
views about science compared to students with unemployed mother, uneducated parents, less books at home, and no separate study
room. Generally, results revealed while family SES correlated positively with tentative views, it was negatively associated
with fixed views, implying that students from high SES family were more likely to believe that knowledge is uncertain and
not handed down by authority compared to students from low SES family. This study, however, failed to indicate any relationship
between father work-status, buying daily newspaper and epistemological beliefs. In addition, Multivariate Analysis of Variance
indicated that boys more likely to have tentative beliefs compared to girls. 相似文献

The purpose of this study was to investigate prospective mathematics teachers’ knowledge of common conceptions and misconceptions
that sixth and seventh grade students had about multiplication of fractions. In addition, prospective teachers’ knowledge
of the sources of these misconceptions and strategies they knew to overcome these misconceptions was examined. Data were collected
from 17 Turkish prospective teachers at the end of the spring semester of the 2004–2005 academic year. A case study design
was used in which data were collected through the Multiplication of Fractions Questionnaire and semi-structured interviews.
The prospective teachers suggested many difficulties that elementary grade level students may have and stated that these difficulties
stemmed from students’ lack of formal knowledge and rote memorization of the algorithms. In addition, the prospective teachers
suggested many strategies that could be used to overcome these misconceptions or difficulties. These strategies could be grouped
under three headings: strategies based on teaching methods, strategies based on formal knowledge of fractions, and strategies
based on psychological constructs. 相似文献

The education of students with special needs in an inclusive environment is becoming more widespread throughout the world. Similarly, in Turkey, the inclusion of students with disabilities has also improved. However, current statistical trends and developments within inclusive education are not well known. The purpose of this study is to provide a statistical analysis of special education data, which were obtained from the Ministry of National Education of Turkey. The findings indicate that some statistical components of special education are missing from most official publications of educational statistics and the number of students and the proportions of special education categories in inclusive education vary from year to year. However, in Turkey, the percentage of students in inclusive education, of all students with special needs, is higher than many European countries. The results show that the number of students with special needs, as well as students in inclusive education, has rapidly increased. Turkey needs to focus on improving the schooling rate of students with special needs, and the quality and variety of special education services within inclusive education. 相似文献

Single subject research is a scientific research methodology that is increasingly used in the field of special education. Therefore, understanding the unique characteristics of single subject research methodology is critical both for educators and practitioners. Certain characteristics make single subject research one of the most preferred methodologies in special education. However, the design is not without limitations. The purpose of this article, by Orhan Cakiroglu, an assistant professor at Karadeniz Technical University, Turkey, is to provide an overview of the single subject research method's critical defining features and basic designs, and discuss what types of research questions single subject research is best suited to answer by providing examples from special education literature. Additionally, the key advantages and limitations of applying single subject research to the field of special education are discussed. 相似文献
