This study performed a content analysis of criteria for student teacher lesson observations stated in protocols from universities in six countries. Similarities across the protocols were the absence of images of the charismatic and the technical-professional teacher, and the dearth of teleological aspects. The degree to which protocols reflected a knowledge base, had clear implementation requirements, valued reasoned judgement, and valued transformation of content varied. On the basis of this range of images of the desired teacher, we suggest four categories of teacher images: the knowledgeable teacher, the knowledge-transforming teacher, the efficient teacher, and the constantly improving… Continue Reading →

It further seeks to determine other influences on teachers’ visions of mathematics and goals for themselves as mathematics teachers. Teachers’ past experiences and knowledge have an impact on their ability to teach mathematics. Autobiographies, or what they are calling math stories, provide one way to study these experiences. Through the powerful lens of mathematics stories, this study seeks to view teachers’ past experiences, to begin to deconstruct possible limiting notions, and to build on solid notions of mathematics and mathematics instruction to better shape classroom practice for tomorrow’s students.

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT This paper briefly overviews my research in supporting children to learn number concepts by relating number words, research-based visual supports, and math symbols. I first outline my approach to helping children build relationships between the use of concrete materials and the building of abstract concepts. I then focus on two crucial early aspects of building meanings for numbers: (1) understanding break-apart partners such as 5=3+2 that support addition and subtraction with small numbers and children’s moving on to Level 2 counting on and algebraic problem representations, and (2) the use of visual five-groups in understanding numbers 1–1000 and in drawings to support multi-digit computations. The research-based learning path of visual-spatio supports is shown and discussed for each topic,… Continue Reading →

eric.ed.gov har udgivet: There are different perspectives in the literature on the examination of visual images used in course books. In this study, illustrations from the visuals used in geometry in the lower learning area of school mathematics were examined and summarized first by researchers and then by teachers and students. For many students, the mathematics coursebook is the first material they encounter in understanding the course content and conveying the mathematics culture. In this study, the illustrations related to the concept of Angle used in mathematics coursebook, two books published abroad, two books published in Turkey, for 5th-grade students were analyzed. The type of research is Document Analysis and the illustrations were examined in qualitative and quantitative terms. In this way, the study aimed to analyze the contribution of… Continue Reading →

ABSTRACT The following article deals with the possibility of discovering several parameters of the picture when using Google Maps images, e.g. time and date of taking the image. This is possible with all pictures in which buildings, trees, poles (‘objects’) can be seen with their shadows. In some cases, one can find – with a bit of luck – an aircraft shortly before landing or shortly after take-off at a big and busy airport. If one detects such a… Continue Reading →
