I have the core ideas for teaching critical thinking and now need them shaped into a full learning package for Indonesian high-school students. The end goal is a set of class-ready materials that guides teenagers to question assumptions, analyse information, and draw reasoned conclusions. Here’s what I already have: the main concepts, some real-life examples, and the flow of discussion. What I need from you is the educational design—turning those notes into an engaging lesson plan, clear explanations, and interactive activities that match the cognitive level of Sekolah Menengah Atas learners. When the project is complete, I want: • A teacher-facing lesson plan (45–60-minute blocks, enough for 2-3 meetings) with objectives, timing, and assessment ideas. • A student handout or workbook that walks them through each thinking step with short readings, guiding questions, and space for reflection. • A concise slide deck that visualises key points and prompts discussion. • One practical exercise that lets students test their critical-thinking skills on a topical issue they recognise from daily life. Please keep the language accessible, include local contexts or examples where helpful, and structure the content so any SMA teacher can pick it up and run the class without extra prep. If you have experience with Kurikulum Merdeka or similar frameworks, mention how you will align the activities. I’ll share my draft notes as soon as we start and will be available for quick feedback rounds to keep the momentum.
