Why This Matters

Curriculum design models aren't just theoretical frameworks gathering dust in education textbooks—they're the architectural blueprints that determine how learning experiences get built from the ground up. When you understand these models, you're gaining insight into why schools teach what they teach, how they sequence learning, and who gets to make those decisions. These are the foundational questions that shape every classroom, every assessment, and every educational reform initiative you'll encounter.

You're being tested on your ability to distinguish between top-down versus bottom-up approaches, recognize when alignment between objectives, instruction, and assessment matters most, and understand how different models prioritize student needs, teacher expertise, or societal demands. Don't just memorize the names and steps—know what problem each model solves and when you'd recommend one approach over another.


Objective-Driven Models

These models start with a clear destination in mind. The underlying principle is that effective curriculum begins with precisely defined outcomes, then works systematically to achieve them. This approach emphasizes measurability, alignment, and accountability.

Tyler's Rational Model

  • Four fundamental questions—What purposes? What experiences? How organized? How evaluated?—form the backbone of systematic curriculum planning
  • Measurable objectives drive every decision, ensuring that instruction and assessment align with clearly stated educational goals
  • Linear, sequential process makes this model ideal for standardized curricula where accountability and consistency are priorities

Backward Design Model

  • Starts with the end in mind—identifies desired learning outcomes before any instructional planning begins
  • Three-stage framework moves from desired results → acceptable evidence → learning experiences, reversing the traditional planning sequence
  • Assessment-instruction alignment ensures students are prepared for evaluations because assessments are designed first, not as afterthoughts

Understanding by Design (UbD)

  • Essential questions guide inquiry and push students beyond surface-level recall toward deep, transferable understanding
  • Performance tasks serve as primary assessments, measuring whether students can apply knowledge, not just recognize it
  • Transfer of learning is the ultimate goal—students should be able to use knowledge in new, unfamiliar contexts

Compare: Tyler's Rational Model vs. Backward Design—both prioritize clear objectives and alignment, but Tyler's model emerged from behaviorist traditions emphasizing measurable outcomes, while Backward Design emphasizes understanding and transfer. If asked which model best supports deep learning over rote memorization, Backward Design is your answer.


Teacher-Centered and Collaborative Models

These models recognize that the people closest to students—teachers—often have the most valuable insights for curriculum development. The core principle is that effective curricula emerge from practitioner expertise and collaborative dialogue rather than top-down mandates.

Taba's Grassroots Model

  • Bottom-up approach positions teachers as curriculum developers, not just implementers of externally designed materials
  • Seven-step process—diagnosis, objectives, content selection, content organization, experience selection, experience organization, evaluation—provides structured guidance while honoring teacher expertise
  • Needs diagnosis first ensures curriculum responds to actual student needs rather than assumed ones

Walker's Naturalistic Model

  • Context-sensitive design acknowledges that real-world educational settings are messy, complex, and resistant to linear planning
  • Flexibility and adaptability are built into the framework, allowing curriculum to evolve based on classroom realities
  • Collaborative deliberation among educators, students, and community members shapes curriculum through ongoing dialogue rather than predetermined steps

Compare: Taba's Grassroots Model vs. Walker's Naturalistic Model—both value teacher input and collaboration, but Taba provides a structured seven-step process while Walker embraces the messiness of real curriculum work. Use Taba when explaining systematic teacher-led development; use Walker when discussing how curricula actually evolve in practice.


Systems and Comprehensive Models

These models view curriculum development as an ongoing, interconnected process involving multiple stakeholders and continuous improvement. The underlying principle is that curriculum is never "finished"—it requires constant evaluation, feedback, and revision.

Saylor, Alexander, and Lewis Model

  • Comprehensive integration of planning, implementation, and evaluation treats curriculum development as a unified system, not isolated steps
  • Contextual factors—societal needs, community values, student characteristics—must inform every curriculum decision
  • Continuous feedback loops drive ongoing revision, making improvement a permanent feature rather than an occasional event

Oliva Model

  • Dynamic, cyclical process rejects the notion of curriculum as a fixed product—it's always evolving
  • Multiple stakeholders including teachers, administrators, parents, and community members all have legitimate roles in shaping curriculum
  • Four recurring phases—planning, implementing, evaluating, revising—repeat continuously rather than ending with implementation

Compare: Saylor, Alexander, and Lewis vs. Oliva Model—both emphasize comprehensive, ongoing curriculum development, but Saylor et al. focus more on contextual factors shaping initial design, while Oliva emphasizes the cyclical nature of continuous improvement. Both reject one-and-done curriculum development.


Content Organization Models

These models focus less on who develops curriculum and more on how content should be structured for optimal learning. The core principle is that the arrangement and connection of content significantly impacts student understanding and retention.

Spiral Curriculum Model

  • Revisiting concepts at increasing levels of complexity allows students to build on prior knowledge progressively
  • Cumulative learning assumption—each encounter with a concept deepens understanding rather than simply repeating it
  • Cross-grade coherence ensures skills and concepts are reinforced and extended throughout a student's educational journey

Integrated Curriculum Model

  • Cross-disciplinary connections break down artificial subject-area boundaries to create cohesive learning experiences
  • Thematic units allow students to explore concepts from multiple perspectives—seeing how math, science, and social studies intersect around real issues
  • Real-world relevance increases engagement by connecting academic content to authentic problems and experiences

Compare: Spiral Curriculum vs. Integrated Curriculum—both aim to deepen understanding, but through different mechanisms. Spiral curriculum achieves depth through repeated, increasingly complex encounters with the same concepts over time. Integrated curriculum achieves depth through connecting concepts across disciplines at a single point in time.


Student-Centered and Inquiry Models

These models place student learning processes—rather than content coverage or teacher planning—at the center of curriculum design. The underlying principle is that students learn most effectively when actively constructing knowledge through meaningful challenges.

Problem-Based Learning Model

  • Real-world problems serve as the starting point for learning, with content knowledge acquired in service of solving authentic challenges
  • Critical thinking and collaboration develop naturally as students work in groups to investigate, analyze, and propose solutions
  • Self-directed learning emerges as students identify what they need to know and take ownership of their learning process

Compare: Problem-Based Learning vs. Understanding by Design—both prioritize application over memorization, but PBL uses problems as the entry point for learning new content, while UbD uses performance tasks as assessments after instruction. PBL is a pedagogical approach; UbD is a planning framework.

Self-Check Questions

  1. Which two models both emphasize starting with clear objectives but differ in their emphasis on deep understanding versus measurable outcomes? What distinguishes their approaches?

  2. A school district wants teachers to lead curriculum development rather than implement externally designed materials. Which model provides the most structured process for this, and what are its seven steps?

  3. Compare and contrast the Spiral Curriculum Model and the Integrated Curriculum Model. How does each approach achieve deeper student understanding, and in what situations might you recommend one over the other?

  4. If an FRQ asks you to recommend a curriculum model for a school that values ongoing revision and multiple stakeholder input, which two models would be strongest choices and why?

  5. A teacher argues that curriculum should emerge organically from classroom realities rather than follow predetermined steps. Which model best supports this perspective, and how does it differ from Taba's approach?
