In teaching damped and driven harmonic motion, a teacher integrates hands-on experiments, simulations, and graph-based analysis. Students use spring-mass systems and oscilloscopes to vary parameters such as damping, driving frequency, and amplitude, observing resonance phenomena. Collaborative discussions guide them to hypothesize, analyze discrepancies, and interpret energy dissipation and phase relationships. Misconceptions about resonance peaks and damping effects are addressed through targeted remedial interventions, including animated visualizations, stepwise calculations, and conceptual questioning. Which combination of pedagogical strategies MOST effectively supports students' understanding of driven harmonic motion? 1. Conducting hands-on experiments by varying damping and driving frequency 2. Engaging in collaborative discussions to examine resonance and energy dissipation 3. Providing targeted remedial support through animations and step-by-step problem-solving
