It also aids teachers to overcome pedagogical difficulties in teaching ratios and scales. The workshop is based on the theory of distributed cognition, which claims that when a powerful tool such as the graphing calculator takes over routine tasks such as drawing of lines and routine calculations, it allows students to focus on more relevant activities such as understanding the calculations. In addition to all these exciting features, the workshop will also provide a means to evaluate understanding using HOTS items. TI-nspire Calculators.
