Organizational power is an abstract entity which could precisely be explained via a metaphorical fractal. Thus, Sierpinski Triangle, a familiar geometrical fractal has been applied in the paper with the purpose to unfold the fractal characteristics of the power within organizations. Such an approach presumes power characteristics as hierarchical, pyramidal, distributive, recursive, accumulative, dependent, comparative, and unequal. The discussions through the paper could contribute to future organization theorists to form an… Continue Reading →

eric.ed.gov har udgivet: The main purpose of the present research is examining the Turkish and Italian students’ perceptions of the concept of “mathematics teacher” through metaphors. The study group of the research consists of 167 Turkish and 112 Italian students, the total of 279 students in the same age group. Students were asked to use another concept defining what “mathematics teacher” meant for them and to explain why. For this purpose, the data of the research were collected by each student’s completing the statement “A mathematics teacher is like …, because ….” Content analysis technique was used to analyze and interpret the obtained data. According to the findings of the research, the students developed a total of 255 valid metaphors. These metaphors are divided into 9 different conceptual categories according… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: Abstract Abstract In this paper I intend to illustrate Vygotsky’s Zone of Proximal Development (ZPD) and then extend the discussion to scaffolding and its relationship with the ZPD. This is then followed by some concerns raised in literature regarding scaffolding as a concept and as a metaphor which involves analysing the arguments for regarding the role of cultural tools and peers as scaffolds akin to instructors. In consideration of some of the criticisms directed at scaffolding, I introduce the concept of the Two Gradient Model (TGM) which is a descriptive model that attempts to clarify the interaction between the instructor and learner. Furthermore, the TGM also demonstrates the need to differentiate between instructors and cultural tools as scaffolds where the… Continue Reading →

eric.ed.gov har udgivet: The aim of this study was to identify the thoughts of pre-service teachers, who play an important role in the early preschool experience of children in mathematics, towards the concepts of mathematics and education of mathematics with the help of metaphors. The study group of the research consists of a total of 227 pre-service teachers at the Department of Preschool Education, Faculty of Education, Cukurova University in the 2013-2014 academic years. The data of the study were collected by asking pre-service teachers to complete some sentences like “do you think, education of math is like …. in the preschool education; because Math is like …; because….”. The responses obtained from pre-service teachers were categorized by content analysis. As a result of the study, seven categories created by… Continue Reading →
