Personal Elaborated Feedback Design in Support of Students' Conjecturing Processes
Peer reviewed Peer reviewed

Raz Harel; Shai Olsher; Michal Yerushalmy – Research in Mathematics Education, 2024
Conjectures are a key component of mathematical inquiry, a process in which the students raise conjectures, refute or dismiss some of them, and formulate additional ones. Taking a design-based research approach, we formulated a design principle for personal feedback in supporting the iterative process of conjecturing. We empirically explored the…

Kaplan, Abdullah; Ozturk, Mesut; Ocal, Mehmet Fatih – International Journal of Research in Education and Science, 2015
The purpose of this study is to determine students' learning levels in derivative subjects and their misconceptions. In addition, this study aims to compared to the effects of the computer based instruction and traditional instruction in resolving these misconceptions. For this purpose, 70 12th grade students were chosen from high schools in Agri…

Driver, David – Teaching Mathematics and Its Applications: An International Journal of the IMA, 2012
When a Computer Algebra System (CAS) is used as a pedagogical and functional tool in class and as a functional tool in exams, its effect on student achievement can be quite profound. The timing of when students are first introduced to a CAS has an impact on gains in student achievement. In this action research project, the CAS calculator was…

Recognising Equivalent Algebraic Expressions: An Important Component of Algebraic Expectation for Working with CAS
PDF on ERIC Download full text
Ball, Lynda; Pierce, Robyn; Stacey, Kaye – International Group for the Psychology of Mathematics Education, 2003
The ability to recognize equivalent algebraic expressions quickly and confidently is important for doing mathematics in an intelligent partnership with computer algebra. It is also a key aspect of algebraic expectation, the algebraic skill that parallels numeric estimation. The progress in this ability of 50 students learning mathematics with CAS…

Formula 1--A Mathematical Microworld with CAS: Analysis of Learning Opportunities and Experiences with Students
Peer reviewed Peer reviewed
Direct linkDirect link
Gerny, Marianne; Alpers, Burkhard – International Journal of Computers for Mathematical Learning, 2004
In this article we describe a mathematical microworld for investigating car motion on a racing course and its use with a group of grade 12 students. The microworld is concerned with the mathematical construction of courses and functions which describe car motion. It is implemented in the computer algebra system, Maple[R], which provides the means…
