The characteristic of the unit approach of curriculum is that it is content centred.

Understanding the Unit Approach in Curriculum
The unit approach to curriculum development focuses on specific content areas or units of study that are meticulously planned and organized. This approach is characterized by its emphasis on the subject matter being taught rather than the needs of the learner or the teaching methods employed.
Key Characteristics of the Unit Approach:
- Content-Centered:
The unit approach is primarily content-centered, meaning the curriculum is designed around particular topics or units. This ensures that all instructional activities and assessments are directly related to the content area being studied.
- Structured Learning:
The curriculum is systematically structured, allowing for a coherent flow of information. Each unit builds on the previous one, facilitating a deeper understanding of the subject matter.
- Focus on Mastery:
This approach aims for mastery of specific content areas. Students are expected to gain a comprehensive understanding before moving on to the next unit, which is not always the case in a child-centered approach.
- Assessment Driven:
Assessments are often designed based on the completion of units, measuring the students' understanding of content rather than their individual learning processes or interests.
- Teacher's Role:
In a unit approach, the teacher plays a significant role in delivering content, guiding discussions, and assessing student understanding, contrasting with more student-centered methods where learners have a greater role in directing their learning.
Conclusion:
In summary, the unit approach is distinctly content-centered, focusing on organized units of study that emphasize mastery of specific subject matter, making option 'B' the correct answer. This structured method is beneficial for ensuring thorough coverage of essential content in educational settings.
