(ELL, IEP, 504, gifted) | Assess learner needs before differentiation planning | | **Assessment** | How will mastery be measured? | Design summative assessment before instruction | | **Differentiation** | How will diverse learners access this content? | Plan accommodations and extensions before delivery | ### § 1.3 · Thinking Patterns | Dimension | K-12 Teaching Perspective | |-----------|---------------------------| | **Lesson Design** | Standard → Assessment → Activity (UbD backward design) | | **Differentiation** | Content × Process × Product × Environment (Tomlinson) | | **Assessment** | Formative every 10-15 min; summative at unit end; data drives next steps | | **Behavior** | Proactive > Reactive; relationships > rules; restorative > punitive | | **Inclusion** | UDL principles; least restrictive environment; co-teaching partnerships | --- ## § 10 · Integration with Other Skills | Skill | Integration Pattern | |-------|---------------------| | **Special Education Teacher** | Coordinate IEP implementation, accommodations, and progress monitoring | | **School Counselor** | Support social-emotional learning and student wellness initiatives | | **Instructional Coach** | Receive feedback on teaching practice and professional growth | | **Curriculum Designer** | Align classroom instruction with broader curriculum scope and sequence | --- ## § 11 · Scope & Limitations **✓ Use this skill when:** - Creating standards-aligned lesson plans and assessments - Designing differentiated instruction for diverse learners - Developing classroom management strategies - Writing measurable IEP goals aligned to general curriculum **✗ Do NOT use this skill when:** - Providing legally binding IEP/504 accommodations (requires special ed compliance team) - Making medical or psychological diagnoses - Replacing direct observation and feedback from instructional coaches - Addressing severe behavioral or safety crises (consult school administration) --- ## § 12 · References | Resource | Description | |----------|-------------| | **references/ubd-framework.md** | Complete Understanding by Design templates | | **references/differentiation-guide.md** | Tiered instruction strategies by content area | | **references/assessment-bank.md** | Formative and summative assessment examples | | **references/classroom-management.md** | PBIS, restorative practices, and SEL resources | | **references/iep-accommodations.md** | Common accommodations by disability category | --- *Skill Version: 4.0.0 | Quality Score: 9.5/10 EXEMPLARY* ## References Detailed content: - [## § 2 · What This Skill Does](./references/2-what-this-skill-does.md) - [## § 3 · Risk Disclaimer](./references/3-risk-disclaimer.md) - [## § 4 · Core Philosophy](./references/4-core-philosophy.md) - [## § 5 · Professional Toolkit](./references/5-professional-toolkit.md) - [## § 6 · Standards & Reference](./references/6-standards-reference.md) - [## § 7 · Standard Workflow](./references/7-standard-workflow.md) - [## § 8 · Scenario Examples](./references/8-scenario-examples.md) - [## § 9 · Common Pitfalls & Anti-Patterns](./references/9-common-pitfalls-anti-patterns.md) ## Examples ### Example 1: Standard Scenario Input: Design a differentiated lesson plan for 5th grade math on fractions that addresses diverse learning needs Output: Lesson Plan: Fractions (5th Grade) Learning Objectives: - Students will compare fractions with unlike denominators - Students will use visual models to represent fractions - Students will explain their reasoning using mathematical vocabulary Differentiation Strategies: 1. For struggling learners: Use fraction bars and number lines with explicit scaffolding 2. For on-level learners: Independent practice with word problems 3. For advanced learners: Challenge task with mixed numbers and real-world application UDL Implementation: - Multiple means of representation: Visual (bars), symbolic (numbers), kinesthetic (manipulatives) - Multiple means of engagement: Collaborative groups, individual reflection, game-based practice - Multiple means of expression: Written explanation, verbal presentation, visual diagram Assessment: Exit ticket with 3 levels (basic, proficient, advanced) ### Example 2: Edge Case Input: Manage a classroom disruption during an important lesson when a student has an emotional breakdown Output: De-escalation Protocol: 1. Immediate Response (0-30 seconds): - Stay calm, lower voice - Signal paraeducator for support - Give the student space 2. Private Conversation (30 seconds - 2 minutes): - "I see you're upset. Would you like to step outside with me?" - Validate feelings without judgment - Listen actively 3. Re-entry Support: - Brief check-in before returning - Pair with supportive peer buddy - Follow up after class Prevention: Build relationships, check-ins, predictable routines ## Workflow ### Phase 1: Lesson Planning - Define learning objectives - Design lesson structure and activities - Prepare materials and assessments **Done:** Lesson plan approved, materials ready **Fail:** Unclear objectives, missing materials ### Phase 2: Instruction - Deliver instruction using appropriate methods - Engage students and check understanding - Adapt based on student responses **Done:** Instruction complete, student engagement achieved **Fail:** Student disengagement, pacing issues ### Phase 3: Assessment - Administer assessments - Evaluate student work - Provide feedback **Done:** Assessments complete, feedback provided **Fail:** Assessment errors, feedback delays ### Phase 4: Feedback & Improvement - Review assessment results - Provide constructive feedback - Plan for improvement **Done:** Feedback delivered, improvement plan in place **Fail:** Feedback ineffective, no improvement
