Eric.ed.gov – The Mathematical Experiences of Black Males in a Predominantly Black Urban Middle School and Community

eric.ed.gov har udgivet: There is a growing body of research focused on the mathematical experiences of Black males in the United States of America. This research has emerged to challenge the dominant narrative in mathematics education focused on Black males’ low performance on international, national, and state standardized tests. There is very little research that has explored the impact of high-stakes testing in mathematics on Black males in urban areas. Using qualitative research methods, this study examines the middle school mathematics experiences of four Black males and provides insight into their responses to challenges they face in urban communities, schools, and math classrooms. Critical race theory was used to illuminate Black males’ desire to be challenged in the classroom and describe the community, school, and classroom conditions that impact their… Continue Reading

Eric.ed.gov – Vermont Teachers’ Understanding of Mathematical Problem Solving and “Good” Math Problems.

eric.ed.gov har udgivet: For the past five years, Vermont has been developing an innovative statewide assessment system in which portfolios of student work in mathematics and writing are a key element. The use of mathematics portfolios, particularly in elementary school, is a novel aspect of the assessment system. This study examines the elementary school mathematics portfolio assessment and its instructional impact by exploring the conceptions of problem solving, the knowledge of problem-solving strategies, the evaluation of problem-solving tasks, and the instructional practices of 20 fourth-grade teachers. Teachers indicated that the portfolio assessment program has enhanced their understanding of mathematical problem solving and broadened their instructional practices, but that they have encountered difficulty in understanding certain components of the reform and making the relevant changes. Teachers did not share a common… Continue Reading

tandfonline.com – Fluid reasoning, working memory and planning ability in assessment of risk for mathematical difficulties

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT The demands on mathematical problem-solving have increased in almost all school systems internationally and may constitute a barrier for children with special educational needs (SEN). This study explored the role of fluid reasoning (FR), working memory (WM) and complex executive function of planning (EF) in children (N = 62) referred for assessment of SEN, and specifically of risk for mathematical difficulties (MD). Performances on FR, WM and complex EF of planning were used to predict risk for MD. Results showed that planning ability predicted children at risk for MD, beyond FR or WM ability, when comparing with children not at risk for MD. It was concluded that assessing the complex EF of planning in addition to FR and WM ability is… Continue Reading

Eric.ed.gov – Helpwithmaths.com: Students’ Use of Online Mathematical Resources

eric.ed.gov har udgivet: A recent Google search for “Help with maths” produced 57,600,000 results, indicating that there are literally millions of online resources claiming to provide assistance with mathematics. As mathematics educators, however, we remain largely uninformed about students’ use of such resources, particularly when they are self-initiated and often accessed in an out of classroom environment. This paper reports on a study that investigated the resources Grade 8 and 9 students accessed when requiring support with understanding mathematical concepts. The study found that while friends and teachers were often students’ preferred options, they did access online sites, particularly in the later years of schooling. The study has implications for students and teachers including the potential for online resources to both complement and challenge the traditional role of the teacher… Continue Reading

tandfonline.com – Mathematical Knowledge for Teaching: How do Primary Pre-service Teachers in Malawi Understand it?

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: Abstract While a consensus within the field exists that pre-service teachers need adequate knowledge and skills to become effective teachers in mathematics, less is known about how they understand the mathematical knowledge needed for teaching in elementary education. This paper explores how Malawian pre-service teachers understand the mathematical knowledge needed for teaching in primary schools. Written answers to a questionnaire survey, and data from six individual interviews collected at the beginning of the teacher-training programme will be presented. The analytical framework is based on the practice-based theory of mathematical knowledge for teaching, with a specific focus on the domains of the common, horizon and specialised content knowledge. The data revealed that, while taking theoretical courses, pre-service teaches develop only intuitive… Continue Reading

Eric.ed.gov – Evaluation of the Computer and Team Assisted Mathematical Acceleration (CATAMA) Lab for Urban, High-Poverty, High Minority Middle Grade Students. Final Report to the Institute of Education Sciences

eric.ed.gov har udgivet: This project entailed a three-year efficacy evaluation of the Computer and Team Assisted Mathematical Acceleration (CATAMA) Lab developed by the Center for Social Organization of Schools at Johns Hopkins University. The CATAMA Lab was proposed as an immediate and practical approach to addressing the different types of math deficits held by students at urban high-poverty schools. The Lab required only 1 teacher per school reducing staff and professional development requirements. It used multiple instructional techniques (including individualized computer instruction, direct instruction, pair and team learning, and individual instruction) to teach math concepts and skills. By taking the place of an elective it allowed students to continue with their on-grade math class. For a more detailed description of the Lab see Appendix 2. The original goal of the… Continue Reading

Eric.ed.gov – Using the Scientific Method to Engage Mathematical Modeling: An Investigation of pi

eric.ed.gov har udgivet: The purpose of this paper is to explain how to use the scientific method as the framework to introduce mathematical model. Two interdisciplinary activities, targeted for students in grade 6 or grade 7, are explained to show the application of the scientific method while building a mathematical model to investigate the relationship between the circumferences and the diameter of circular objects. In the first activity, a research question is pursued as it relates to the stated hypothesis. In the second activity, the same research question is retained; however, the use of exploration helps to build the hypothesis. The activities serve as examples to show how middle school math teachers may use scientific inquiry to motive students’ understanding of mathematical models as well as engage in science beyond… Continue Reading
