- Abstract
- A pilot study, analysing twenty-one Year 10 students' reflections on a unit of exponential functions taught using real-world problems, and supported by the use of CAS calculators. The real-world contexts explored during the unit provided a focus for follow-up interviews. Detailed analysis of the transcripts revealed four themes: Impact of technology; difficulty in expression; prediction; choice of scenario. Findings support results from related research reported in the literature and highlight the importance of the choice of real-world scenarios. Analysis revealed variation in students' preference relating to scenarios. This variation provides a challenge in the preparation of appropriate material.
