PhD thesis: Developing an Interactive Computer Support System to Facilitate Teacher Learning of
Proof-related Instruction in Mathematics
Research interests:
1. Proof & Proving in the Mathematics Classroom
2. Use of Technology in Teaching and Learning Mathematics
3. Problem Solving & Critical Thinking in School Mathematics
4. The Education and Development of Mathematics Teachers
My PhD focuses on the development of an interactive simulated environment that will offer teachers the opportunity to prepare for the instruction of mathematical proof. Besides a central concept in mathematics, proof is increasingly acknowledged as a focal point in school mathematics, too. Students’ learning of proof is associated with many benefits, including the development of mathematical understanding, critical reasoning and problem-solving skills. However, proof is an alien concept in most classrooms. Thus, students typically have various misconceptions while teachers have very limited opportunities to meaningfully engage with proof-related instruction and refine relevant teaching skills. Headway in addressing this educational problem can be made with the design of a computer support system that will enable teachers to virtually prepare for the incorporation of proof into their classrooms by teaching proof to virtual students before real ones, similarly to how flight simulators help pilots prepare for real flights.
Who or what inspired you to pursue your research interests?
My main sources of inspiration are the supreme beauty of mathematics and the huge educational value I believe it has. Mathematics is undoubtedly one of the most fruitful currents of human thought. From an educational perspective, learning Mathematics can help people develop a critical thinking attitude and a wholesome respect for the use of logical reasoning in everyday life. Examining and enriching the ways in which mathematics is taught and learnt can help the world become a place where the validity of ideas rests on reason. I consider myself fortunate to have the opportunity to contribute to this goal!
