Computational Triangulation in Mathematics Teacher Education

The paper is written to demonstrate the applicability of notion triangulation typically used in social sciences research computationally enhance mathematics education future K-12 teachers. starts with so-called Brain Teaser as background for (what called paper) computational context four digital tools. Computational problem solving and formulating are presented two sides same coin. By revealing hidden Fibonacci numbers included Teaser, discusses role thinking use well-ordering principle, generating function method, fabrication, difference equations, continued fractions development algorithms. These algorithms eventually lead a generalized Golden Ratio form string independently generated by tools paper.
