When considering the use of calculators, what should Mr. Jansen remember for his learning-disabled students?

The correct approach for Mr. Jansen to consider is that learning-disabled students should have the option to use a calculator after they have demonstrated understanding of mathematical concepts. This practice acknowledges the importance of both learning foundational skills and providing support through the use of technology.

Using calculators can help these students engage with more complex problems that they might otherwise struggle with due to their learning disabilities, allowing them to focus on understanding concepts rather than getting bogged down in calculations. This also reinforces the idea that calculators are tools to aid learning rather than crutches that prevent learning. Offering the option to use calculators after a solid grasp of the concepts promotes both independence and confidence in their mathematical abilities, ultimately fostering a more inclusive learning environment.
