eric.ed.gov har udgivet: Math Teachers’ Circles (MTCs) are an innovative, problem-solving focused approach to professional development. This model provides teachers opportunities to develop their problem solving skills as well as help them to communicate with others on classroom implementation of problem-solving activities. As with any professional development with teachers, it is important to explore the impact of this model in terms of teachers’ learning and development. In this report we provide our implementation of a zone theory lens provided by Goos as a way to investigate the MTC model. Initial analysis implementing this particular theoretical lens helps us gain insights in ways to improve this new model of professional development activities for future participants.

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT There is a growing awareness that many children are not developing fast and accurate retrieval-based strategies for solving single-digit addition problems. In this study we individually assessed 166 third and fourth grade children to identify a group of children (called accurate-min-counters) who frequently solved simple single-digit addition problems using a min-counting strategy and were accurate using it. We investigated if these children were adaptive when it came to using retrieval for simple addition and if they were disadvantaged when it came to demonstrating mental computational flexibility with multi-digit addition. We found accurate-min-counters represented over 30% of participants. These children were often incorrect when they were required to use retrieval for simple addition and were less flexible than most… Continue Reading →

eric.ed.gov har udgivet: The purpose of this research is to determine pre-service mathematics teachers’ skills in the development of activities. The research was carried out using the case study which is descriptive method. For the collection of data, 57 pre-service mathematics teachers’ in their final year secondary math teachers’ education department attended the research. Pre-service teachers were asked to develop 5 activities for the concept of function a high school mathematics curricula. After obtaining the data, it was analyzed using the descriptive analysis method. The developed activities were first examined to see if they qualified as activities, which would be used in the learning process stage, and then examined to see which skills were reflected in the activities. The findings indicated that more than half of the pre-service teachers could… Continue Reading →
