The current study employed the content analysis approach to investigate the multiple mathematical representations and transitions among them in 8th Grade Mathematics Textbook. An observation method was used to analyses the teacher practices (n=35 observations), and record the representations and transitions. The results showed that there was an existence of symbol and verbal representations in the textbook and teachers’ implementation. Meanwhile, the other three representations (pictures and figures, models and Cutters, and life situations) and the transactions between them were at low rates in the textbook and teachers’ implementation.

eric.ed.gov har udgivet: Instructors in higher education are very familiar with the Likert scale Students’ Evaluation of Teaching (SET) used to evaluate teaching. Researchers have raised concerns about biases affecting the results of SET surveys, as well as their validity and reliability and use in high-stakes decision making. Here, we demonstrate that Q methodology, identified as an 80-year-old mixed method, is better suited to determine the differing student views about a college math education course. We will discuss how Q used for SET can produce results that are more helpful in assisting faculty in improving their teaching effectiveness and in redesigning courses while also providing more informative SET results for faculty evaluations.

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT It is well known that students benefit from opportunities to interpret and create different representations (e.g., diagrams, graphs, tables, symbols) of mathematical ideas. Employing Marton’s Variation theory as a lens, I argue for an expansion of the use of multiple representations in task design for graphs: Incorporate two different forms of the same type of graph to represent a relationship between variables in a situation. With this approach, designers, teachers, and researchers can engineer opportunities for students to discern, or separate, features of representation systems, such as the Cartesian coordinate system, and in turn, promote students’ mathematical reasoning.
