After most students passed a summative test but some failed, strategic intervention material (SIM) is recommended to help students master skills they did not develop in regular classes. SIM uses learning strategies and content enhancement for students and teachers, respectively, and requires less supervision than regular classes. SIM focuses on specific skills not mastered by students and may cover different topics than regular classes. It includes guide cards, activity cards, assessment cards, enrichment cards, and reference cards to engage students and assess their mastery of skills. Teachers should ensure SIM activities align with objectives and keep activities short, simple, and varied to accommodate different learning styles.
