Models of Curriculum Development - Tyler's Model, Hilda Taba's Grassroots Rational Model, Saylor & Alexander's Planning process Model

 


📘 Models of Curriculum Development

Curriculum development is a systematic and planned process that aims to bring about desirable changes in learners through structured educational experiences. While curriculum experts differ in their views and ideologies, they all agree on certain fundamental components and questions that guide the design of a curriculum.

Three major models commonly discussed in curriculum development are:

  • 🌀 Tyler’s Curriculum Inquiry Model
  • 🌿 Hilda Taba’s Grassroots Rational Model
  • 🛠️ Saylor and Alexander’s Planning Process Model

Let’s explore these in detail:


🔷 1. Tyler’s Curriculum Inquiry Model (1949)

📖 Introduction:

Ralph Tyler is considered one of the pioneers in the field of curriculum development. His model, described in his classic work "Basic Principles of Curriculum and Instruction", laid the foundation for many modern educational planning frameworks.

Tyler proposed that every curriculum should be built around four fundamental questions, which guide the entire teaching-learning process.


Tyler's Four Basic Questions:

1.   🎯 What educational purposes should the school seek to attain?
– This refers to identifying clear instructional objectives.

2.   📚 What educational experiences can be provided to attain these purposes?
– This involves choosing meaningful learning experiences that match the objectives.

3.   🧩 How can these learning experiences be effectively organized?
– Here, the focus is on sequencing and structuring content in a way that promotes learning.

4.   📊 How can we determine whether these purposes are being attained?
– This emphasizes the role of evaluation in assessing learning outcomes.

Purpose of the School

Selection of Learning Experiences

Organization of Learning Experiences

Evaluation


🏫 Step 1: Purpose of the School

Tyler suggested that curriculum objectives should be derived from three major sources:

  • 📖 Subject Matter – The knowledge content from various academic disciplines.
  • 👨‍🎓 Learners – The needs, interests, and developmental levels of students.
  • 🌍 Society – The expectations, values, and demands of the community and nation.

These broad objectives are then refined by passing them through two screens or filters:

  • 🧭 Philosophy of Education – Ensures alignment with the school’s ideals and values.
  • 🧠 Psychology of Learning – Ensures they are developmentally appropriate and realistic.

🔸 The outcome is a set of specific instructional objectives that guide teaching.


📘 Step 2: Selection of Educational Experiences

  • The learning experiences must match the objectives and enable learners to achieve the desired outcomes.
  • These experiences can be both cognitive (knowledge-based) and affective/psychomotor (skills and values).
  • Teachers should ensure that the experiences are engaging, varied, and meaningful to students.

🧩 Step 3: Organization of Learning Experiences

  • Learning should not be a random process; it must be logically organized.
  • Tyler emphasized three principles of organization:
    • 🌀 Continuity – Repeated emphasis on key ideas over time.
    • 🔁 Sequence – Progressive complexity from simple to advanced.
    • 🔗 Integration – Interconnection of ideas across subjects and experiences.

📈 Step 4: Evaluation

  • Evaluation is the process of determining whether the learning objectives have been achieved.
  • It must involve both formative (ongoing) and summative (final) assessments.
  • Evaluation results are used to:
    • Continue effective practices
    • ⚠️ Modify weak areas
    • Discontinue ineffective strategies




Merits of Tyler’s Model

  • Provides a clear, structured, and logical framework.
  • Emphasizes the importance of objectives in planning.
  • Encourages goal-oriented teaching and learning.
  • Promotes accountability through evaluation.

Demerits of Tyler’s Model

  • Considered too rigid and linear for dynamic classrooms.
  • Evaluation comes after implementation — may lead to delayed corrective action.
  • Less emphasis on creativity, spontaneity, and learner participation.
  • Assumes that objectives can always be clearly stated, which is not always true.

🌿 2. Hilda Taba’s Grassroots Rational Model

📖 Introduction:

Hilda Taba, an educational thinker, argued that teachers, being closest to learners, should be the main designers of curriculum. She emphasized an inductive approach, starting from specific classroom situations to build general curriculum designs.

Unlike Tyler’s top-down model, Taba’s approach is more bottom-up and participative.


🪜 Seven Steps in Taba’s Model:

1.   🩺 Diagnosis of Needs

o   The teacher identifies gaps in student knowledge, interests, or skills.

o   Based on real classroom experiences and local context.

2.   🎯 Formulation of Objectives

o   Specific objectives are developed from diagnosed needs.

o   These guide the rest of the curriculum process.

3.   📖 Selection of Content

o   Teachers choose content that is:

§  Relevant to objectives

§  Academically valid

§  Socially significant

4.   📚 Organization of Content

o   Content is sequenced from simple to complex.

o   Takes into account:

§  Student maturity

§  Prior knowledge

§  Logical flow

5.   Selection of Learning Experiences

o   Instructional methods are selected to help students interact with the content.

o   Encourages active participation and engagement.

6.   🔄 Organization of Learning Activities

o   Activities are structured in a way that supports the content and objectives.

o   Ensures continuity and integration in learning.

7.   📏 Evaluation and Means of Evaluation

o   Methods are devised to check whether objectives are achieved.

o   Can include tests, observations, portfolios, etc.


Merits of Taba’s Model

  • Empowers teachers as curriculum developers.
  • Emphasizes learner-centeredness.
  • Promotes grassroots-level planning.
  • Encourages collaborative and reflective teaching.

Demerits of Taba’s Model

  • Assumes that all teachers have sufficient training and time for curriculum planning.
  • May not be practical in highly centralized education systems.
  • Can be time-consuming and require more effort.

🛠️ 3. Saylor and Alexander’s Planning Process Model (1974)

📖 Introduction:

Galen Saylor and William Alexander proposed a comprehensive curriculum model with an administrative perspective. Their model emphasizes planning as a systematic and feedback-driven process, ensuring alignment between goals, implementation, and evaluation.


🗂️ Key Features of the Model:

  • Curriculum is viewed as a plan to provide educational opportunities for learners in a specific setting (school, region).
  • It integrates external influences, internal goals, and feedback loops to continuously improve instruction.


🌍 External Forces Influencing the Curriculum

These are the outside influences that shape the planning and content of the curriculum. Curriculum developers must consider:

  • 📜 Legal Requirements – Educational laws, acts, and policies that must be followed.
  • 🔬 Educational Research Data – Insights from studies that guide what works best in teaching and learning.
  • 🧑‍🔬 Professional Standards and Associations – Guidelines provided by teacher associations, boards, and educational experts.
  • 🏛️ Government Policies and Guidelines – Central and state frameworks like NEP (National Education Policy), SCERT, NCERT, etc.

These forces help ensure that the curriculum is up-to-date, relevant, and aligned with national educational goals.

🎯 Bases of Curriculum

These are the internal foundations that guide how and why curriculum decisions are made:

  • 🏙️ Society – The curriculum must reflect the cultural, economic, and moral values of the society in which the learners live.
  • 👨‍🎓 Learners – Understanding students’ age, interest, background, and learning style is crucial.
  • 📚 Knowledge – The body of subject matter, disciplines, skills, and competencies that students need to learn for success in life.

These bases ensure that the curriculum is learner-centered, socially relevant, and knowledge-rich.

🎯 Goals, Objectives, and Domains

In Saylor and Alexander’s model, goals and objectives serve as the starting point and backbone of curriculum development. They define what the curriculum intends to achieve and guide all decisions related to content, teaching methods, and evaluation.

🧩 Goals vs. Objectives

  • Goals are broad, general statements about desired outcomes of education.
  • Objectives are specific, measurable, and describe what students should be able to do after instruction.

These are not formed in isolation — they are influenced by both external forces and internal curriculum bases.


🗃️ Four Major Domains of Educational Goals

Saylor and Alexander identified four essential curriculum goal domains, which together ensure the holistic development of learners:

1.   🌱 Personal Development

o   Focuses on the individual’s emotional, moral, and creative growth.

o   Encourages self-awareness, aesthetic sense, confidence, and values.

2.   🤝 Human Relations

o   Aims to develop social skills and ethical responsibility.

o   Promotes cooperation, empathy, respect, and democratic behavior.

3.   🔄 Continued Learning Skills

o   Prepares learners for lifelong learning.

o   Enhances critical thinking, problem-solving, and learning-to-learn strategies.

4.   🎓 Specialized Learning

o   Involves subject-specific knowledge or vocational training.

o   Tailors learning to future careers, talents, or academic pursuits.


📈 Process of Curriculum Planning

This model follows a systematic and cyclic process:

1.   🧭 Set Clear Goals and Objectives – Based on learner needs, societal expectations, and research data.

2.   🏗️ Design Curriculum – Decide on content, methods, and structure to offer meaningful learning opportunities for each domain.

3.   👩‍🏫 Implement the Curriculum – Teachers execute the plan through instructional strategies, teaching materials, and classroom practices.

4.   📊 Evaluate the Curriculum – Check whether learning objectives have been achieved effectively.

5.   🔄 Use Feedback for Revision – Continuously improve the curriculum based on feedback and outcomes.

This approach allows for flexibility and improvement over time.


Merits of Saylor & Alexander's Model

  • 🏢 Strong Administrative and Systemic Approach
    Offers a clear, organized method for curriculum development that schools and institutions can follow easily.
  • 🔁 Allows Flexibility through Feedback and Revision
    Feedback loops enable ongoing updates to curriculum based on outcomes and student needs.
  • 🌐 Recognizes External and Internal Influences
    Integrates both external mandates and internal learner-centric values, making the curriculum more balanced.
  • 📊 Encourages Data-Driven Decisions
    Emphasizes using research and real-world data to make informed choices in planning and evaluation.

⚠️ Demerits of Saylor & Alexander's Model

  • 🏢 Requires Strong Administrative Support
    The model depends on a structured planning system with trained personnel and institutional backing. It is difficult to implement in under-resourced schools lacking infrastructure or professional curriculum teams.
  • 🧩 Coordination Complexity
    Involves multiple stakeholders (teachers, administrators, experts, government bodies), which can lead to communication gaps, delays, or inconsistency in execution. Smooth collaboration is often difficult to maintain in large systems.

Conclusion:

Each model has its own philosophy and method. Tyler emphasizes clarity and objectivity, Taba focuses on teacher-driven planning, while Saylor and Alexander integrate administrative and feedback-driven approaches. Educators can use these models individually or in combination, depending on their educational goals, context, and resources.
