•
Numerical tables enable systematic comparison of design
alternatives.
3. Supporting differentiated learning:
•
Struggling students use graphical analysis to build
intuition before symbolic manipulation.
•
Advanced learners employ the GDC to explore the
sensitivity of solutions to parameter changes.
4. Enhancing inquiry-based exploration:
•
Immediate visual feedback allows students to test
hypotheses and refine models.
•
Technology-mediated calculations let students focus on
interpreting results rather than arithmetic.
Key takeaways:
1. Students solve real optimization problems by calculating
aquarium volumes and minimising material costs using
derivatives and integrals.
2. Inquiry-based approach with hands-on modeling,
collaborative problem-solving, and TI-Nspire visualization
makes calculus tangible.
3. Tiered tasks with scaffolding for struggling students and
advanced extensions ensure all learners are challenged.
Remember:
Participants must bring either a TI-Nspire CX (with Student
Software installed from education.ti.com) or Casio fx-CG50
calculator. Ensure you can perform: graphing functions, find
minima/maxima (TI: fMin/fMax, Casio: G-SOLVE), and
generate tables. Test these functions beforehand.
