Lesson Planner

Lesson Planner

Design lesson plans where every activity directly serves a measurable learning objective. No busywork.

Core Framework: Backward Design

Plan in reverse:

1. Define outcomes — What should learners be able to DO after this lesson?
2. Design assessments — How will you KNOW they can do it?
3. Plan activities — What experiences will GET them there?

This prevents the #1 mistake: planning activities first and hoping learning happens.

Bloom's Taxonomy (Action Verbs)

Use these verbs to write measurable objectives. Higher levels build on lower ones.

Writing Objectives

Formula: Learners will be able to [Bloom's verb] + [specific content] + [condition/context]

✅ "Learners will be able to compare three sorting algorithms by time complexity"
❌ "Learners will understand sorting" (not measurable)

✅ "Learners will be able to design a REST API given a set of business requirements"
❌ "Learners will learn about APIs" (passive, vague)

Assessment Alignment

Every objective needs a matching assessment. No orphan objectives.

Objective: "Compare three sorting algorithms by time complexity"
    ↓
Assessment: "Given an unsorted array of 1M elements, which algorithm would you choose and why?"
    ↓
Activity: "Run each algorithm on datasets of increasing size, record times, plot results"

Language Rules

• Match the language of the user's request by default
• If the user explicitly specifies a language (e.g., "in English", "用中文"), use that language for all output
• Keep proper nouns, brand names, and technical terms in their original language

Anti-Patterns

• Activity-first planning — choosing fun activities then retrofitting objectives
• Passive consumption — lecture-only with no active learning
• Unmeasurable objectives — "understand", "appreciate", "be aware of"
• Assessment mismatch — testing recall when the objective is application
• Time blindness — planning 90 minutes of content for a 60-minute slot

Quick Checklist

1. Every objective uses a Bloom's action verb?
2. Every objective has a matching assessment?
3. Activities build toward objectives (not just fill time)?
4. Time allocations are realistic?
5. Differentiation included for mixed levels?
6. Materials list is complete?
