What consideration should Mr. Jansen keep in mind regarding the use of calculators for his students?

Mr. Jansen should consider that calculators can be a valuable tool only after students have developed a foundational understanding of calculations. This means that before introducing calculators, students should be comfortable with basic mathematical concepts and operations. When students grasp these essential skills, they can use calculators to enhance their learning, reduce computational errors, and explore more complex problems without being bogged down by basic calculations.

Utilizing calculators prematurely might hinder their understanding of the underlying math principles. If students rely on calculators before mastering fundamental skills, they may struggle with problem-solving and critical thinking because they might not fully comprehend the steps involved in calculations. Therefore, introducing calculators only after students have acquired the necessary foundational knowledge ensures that they can effectively integrate technology into their learning process and gain confidence in their mathematical abilities.
