# Teaching Design Frameworks Reference

## 1. Bloom's Revised Taxonomy (Anderson & Krathwohl, 2001)

### Cognitive Process Dimension

| Level | Category | Definition | Key Verbs |
|-------|----------|------------|-----------|
| 1 | Remember | Retrieve relevant knowledge from long-term memory | Define, duplicate, list, memorize, recall, repeat, state, identify, name, recognize |
| 2 | Understand | Construct meaning from instructional messages | Classify, describe, discuss, explain, identify, locate, paraphrase, report, select, summarize, translate, interpret |
| 3 | Apply | Carry out or use a procedure in a given situation | Execute, implement, solve, use, demonstrate, interpret, operate, schedule, sketch, calculate |
| 4 | Analyze | Break material into constituent parts; determine how parts relate to each other and to an overall structure | Differentiate, organize, relate, compare, contrast, distinguish, examine, experiment, question, test, deconstruct |
| 5 | Evaluate | Make judgments based on criteria and standards | Appraise, argue, defend, judge, select, support, value, critique, justify, weigh, prioritize |
| 6 | Create | Put elements together to form a coherent or functional whole; reorganize elements into a new pattern or structure | Design, assemble, construct, conjecture, develop, formulate, author, investigate, produce, plan, compose |

### Knowledge Dimension

| Type | Description | Example |
|------|-------------|---------|
| Factual | Basic elements students must know | Terminology, specific details and elements |
| Conceptual | Interrelationships among basic elements | Classifications, categories, principles, generalizations, theories, models, structures |
| Procedural | How to do something; methods of inquiry; criteria for using skills, algorithms, techniques, methods | Subject-specific skills, techniques, methods; criteria for determining when to use appropriate procedures |
| Metacognitive | Awareness and knowledge of one's own cognition | Strategic knowledge, cognitive tasks, self-knowledge |

### Taxonomy Table (2D)

Use this table to classify learning outcomes by both cognitive process and knowledge type:

```
                 Remember  Understand  Apply  Analyze  Evaluate  Create
Factual          [   ]     [   ]      [   ]   [   ]    [   ]    [   ]
Conceptual       [   ]     [   ]      [   ]   [   ]    [   ]    [   ]
Procedural       [   ]     [   ]      [   ]   [   ]    [   ]    [   ]
Metacognitive    [   ]     [   ]      [   ]   [   ]    [   ]    [   ]
```

## 2. Backward Design (Wiggins & McTighe, 2005)

### The Three Stages in Detail

**Stage 1: Identify Desired Results**

Key questions:
- What worthy goals does this address? (Standards, program outcomes, institutional goals)
- What enduring understandings are desired? (Big ideas that transfer)
- What essential questions will be explored? (Provocative, open-ended, recurring)
- What key knowledge and skills will students acquire?

Priority framework for content:
```
┌─────────────────────────────────────────┐
│         Worth being familiar with        │  (Peripheral knowledge)
│    ┌─────────────────────────────────┐   │
│    │    Important to know and do      │   │  (Core content and skills)
│    │   ┌─────────────────────────┐   │   │
│    │   │   Enduring              │   │   │  (Big ideas, transfer)
│    │   │   Understanding         │   │   │
│    │   └─────────────────────────┘   │   │
│    └─────────────────────────────────┘   │
└─────────────────────────────────────────┘
```

**Stage 2: Determine Acceptable Evidence**

Types of assessment evidence (GRASPS for performance tasks):
- **G**oal: What is the goal of the task?
- **R**ole: What role does the student play?
- **A**udience: Who is the audience?
- **S**ituation: What is the context/scenario?
- **P**roduct/Performance: What will students create?
- **S**tandards: By what criteria will work be judged?

**Stage 3: Plan Learning Experiences and Instruction (WHERETO)**

- **W** — Where are we going? Why? What is expected?
- **H** — How will we hook and engage students?
- **E** — How will we equip students for expected performances?
- **R** — How will we help students rethink and revise?
- **E** — How will students self-evaluate and reflect?
- **T** — How will we tailor learning to varied needs, interests, and styles?
- **O** — How will we organize and sequence the learning?

## 3. Constructive Alignment (Biggs et al., 2022)

### The SOLO Taxonomy

Biggs's Structure of the Observed Learning Outcome (SOLO) taxonomy complements Bloom's:

| Level | Description | Student Response |
|-------|-------------|-----------------|
| Pre-structural | Misses the point entirely | Irrelevant information, tautology |
| Uni-structural | Focuses on one relevant aspect | Can identify, name, follow simple procedure |
| Multi-structural | Addresses several relevant aspects but treats them independently | Can enumerate, describe, list, combine |
| Relational | Integrates several aspects into a coherent whole | Can compare, relate, analyze, apply, explain causes |
| Extended abstract | Generalizes beyond what was taught to new domains | Can theorize, generalize, hypothesize, reflect, create |

### Alignment Principles

1. Clearly state intended learning outcomes (ILOs) using verbs that specify the level of understanding required
2. Design teaching/learning activities (TLAs) that require students to perform at the same cognitive level as the ILOs
3. Design assessment tasks (ATs) that require students to demonstrate the same cognitive performances specified in the ILOs
4. Transform grading criteria into rubrics that specify the quality levels of the performances

### Verbs for Alignment

```
ILO Verb         →  TLA Design                    →  AT Design
─────────────────────────────────────────────────────────────────
"Explain"        →  Discussion, teach-back         →  Short answer, oral exam
"Apply"          →  Problem sets, lab work          →  Applied problem, case study
"Analyze"        →  Case study discussions          →  Analytical essay, report
"Evaluate"       →  Debate, peer review             →  Critical review, position paper
"Create"         →  Project-based learning          →  Portfolio, design project
```

## 4. Fink's Taxonomy of Significant Learning (2013)

Fink's taxonomy is non-hierarchical and interactive. Six categories of significant learning:

| Category | Description | Key Questions |
|----------|-------------|---------------|
| Foundational Knowledge | Understanding and remembering information and ideas | What key information is important for students to understand and remember? |
| Application | Skills, critical/creative/practical thinking, managing projects | What kinds of thinking are important? What skills do students need to learn? |
| Integration | Connecting ideas, people, and realms of life | What connections should students recognize and make? |
| Human Dimension | Learning about oneself and others | What should students learn about themselves? About interacting with others? |
| Caring | Developing new feelings, interests, and values | What changes in feelings, interests, or values would be important? |
| Learning How to Learn | Becoming a better student, self-directing learner | What would students need to learn for them to continue learning after the course? |

## 5. Universal Design for Learning (CAST)

> **Version note:** CAST released **UDL Guidelines 3.0** on 2024-07-30, superseding 2.2. The three principles below (Engagement / Representation / Action & Expression) are stable across versions, but 3.0 reorganized and relabeled the underlying guidelines/checkpoints and added an explicit focus on removing barriers rooted in bias and exclusion.

## 6. Pedagogical Content Knowledge (Shulman, 1986)

Effective teaching requires the intersection of:
- **Content Knowledge (CK)**: Deep understanding of the discipline
- **Pedagogical Knowledge (PK)**: Understanding of teaching and learning processes
- **Pedagogical Content Knowledge (PCK)**: Understanding of how to teach specific content to specific learners

Key components of PCK:
1. Knowledge of student preconceptions and misconceptions in the discipline
2. Knowledge of representations, analogies, examples, and explanations that make content accessible
3. Knowledge of what makes specific topics easy or difficult to learn
4. Knowledge of curriculum — horizontal (across courses) and vertical (across levels)
