As the descriptive approach is said to be what is prevailing, the prescriptive approach is how it should be.
Based upon the values, rules, and laws the prescriptive approach is referred to be historical in nature.
Where a set procedure has come up after a lot of deliberation and trials and considered to be the right option.
In education, the prescriptive approach can be related to idealist, realist, perennial, or essentialist philosophies because it is strict and somewhat rigid in nature.
In the prescriptive educational approach, the textbooks are prescribed and are provided to the students and only those concepts are studied which are considered essential and harmonious to the societal needs.
The students have a limited choice and more stress is laid on the subjects, that are more scientific and utility-based.
Ethics remain important and are considered as the tool kit for the survival of a nation.
The prescriptive approach is based on the belief that the order, stability, and discipline in the world are due to the fixed laws and principles.
If the laws and principles are flexible an injustice would creep in and thus peace would be jeopardized.
The prescriptive approach stresses more on the conceptual understanding of the facts then producing new reasons to justify.
Advantages of Prescriptive Approach
The prescribed textbooks provide a well balanced chronological development of
information to the students.
Books are more helpful for the teachers with weak cognitive ability and teaching skills, where complete lesson design and the exercises are well laid out.
The approach standardizes the ability level of students for assessment and grades.
Moreover, the textbooks provide a lead to calculate time and space in advance.
The prescriptive approach provides a uniform standard of ethics and values for the entire community which provides a better discipline and social norms.
The disadvantage of the Prescriptive Approach
The prescriptive approach shuts down the novelty and creativity from the students since books are designed on a singular theme.
The information and knowledge changes rapidly and textbooks soon are outdated.
The students are tested for only factual knowledge and books do not cater for the background knowledge of the students.
