Garofalo, Joe; Trinter, Christine P. – Mathematics Teacher, 2012
By working through well-designed tasks, students can expand their thinking about mathematical ideas and their approaches to solving mathematical problems. They can come to see the value of looking at tasks from different perspectives and of using different representations. This article discusses four tasks that encourage high school students and…

Duda, Janina – International Journal for Technology in Mathematics Education, 2011
Teaching mathematics using graphic calculators has been an issue of didactic discussions for years. Finding ways in which graphic calculators can enrich the development process of creative activity in mathematically gifted students between the ages of 16-17 is the focus of this article. Research was conducted using graphic calculators with…

Hong, Dae S. – International Journal of Mathematical Education in Science and Technology, 2011
In its mathematics standards, National Council of Teachers of Mathematics (NCTM) states that problem solving is an integral part of all mathematics learning and exposure to problem solving strategies should be embedded across the curriculum. Furthermore, by high school, students should be able to use, decide and invent a wide range of strategies.…

Teachers' Use of Computational Tools to Construct and Explore Dynamic Mathematical Models
Peer reviewed Peer reviewed
Direct linkDirect link
Santos-Trigo, Manuel; Reyes-Rodriguez, Aaron – International Journal of Mathematical Education in Science and Technology, 2011
To what extent does the use of computational tools offer teachers the possibility of constructing dynamic models to identify and explore diverse mathematical relations? What ways of reasoning or thinking about the problems emerge during the model construction process that involves the use of the tools? These research questions guided the…

Helping Students Make Sense of Logarithms and Logarithmic Relationships
Peer reviewed Peer reviewed
Direct linkDirect link
DePierro, Ed; Garafalo, Fred; Toomey, Rick – Journal of Chemical Education, 2008
This paper summarizes difficulties that chemistry students at all levels commonly exhibit when translating, manipulating, and interpreting mathematical expressions that contain logarithms, and offers approaches that the authors have found useful to help students overcome such difficulties. The online supplement provides problem sets created by the…

Establishing Computer Science Professional Norms among High-School Students
Peer reviewed Peer reviewed
Direct linkDirect link
Kolikant, Yifat Ben-David; Pollack, Sarah – Computer Science Education, 2004
Norms govern the criteria by which students decide what is good and what is not good, and align their learning trajectories accordingly.We found that the high-school students' norm is to produce working, but not necessarily error-free, programs and to argue for their correctness solely on the basis of a few executions. Therefore, they prefer…
