In today’s rapidly evolving realm of education technology, evaluating descriptive answers poses a big challenge to the institutes. With an ever-growing number of students and lengthy responses to assess, the traditional method of manual evaluation has proven to be both time-consuming and error-prone which leads to delays in result processing.

Fortunately, the innovation of Artificial Intelligence (AI) offers a promising solution to automate and expedite the manual evaluation process. This article dives into the issue of manual evaluation within the education sector, highlights the potential of AI to assist in this crucial task and explores the remarkable impact it can have on educational institutions.

Let us begin by understanding the problems faced by educational institutions.

🎯The Problem of Manual Evaluation in the Education Sector

Evaluating descriptive answers manually can be a daunting task, particularly when the faculty needs to go through a high volume of responses that need to be carefully read and assessed. Institutes grappling with thousands of students often find it increasingly challenging to ensure accurate and efficient evaluation.

Human evaluators, despite their expertise, are prone to fatigue and oversight, which can hinder their ability to assign appropriate marks based on the quality of each answer. This manual process not only consumes a significant amount of time but also increases the possibility of subjective evaluation and errors.

💡The Limitations of Manual Evaluation

1. Experiencing fatigue, inconsistency, and subjectivity

Human evaluators may experience fatigue and inconsistency as they navigate through numerous responses, potentially impacting the fairness and consistency of grading. Moreover, subjectivity may mistakenly influence their assessment skills which can lead to discrepancies in marking standards.

2. Potential for errors and biases in manual evaluation

The potential for errors and biases in manual evaluation is an important concerning factor. Even the most diligent evaluators may unknowingly overlook certain aspects or misinterpret answers, which can have a significant impact on student’s results. This subjective nature of manual evaluation raises concerns about the reliability and objectivity of the process.

Examples illustrating the drawbacks of manual evaluation in the education sector

  • Example 1

Each faculty member needs to read each and every answer meticulously to assign marks appropriately. In the case of thousands of students, this task becomes extremely time-consuming owing to various reasons such as deciphering handwriting and interpreting unclear or ambiguous explanations. 

  • Example 2

The teacher may need to refer to textbooks, reference materials, or marking schemes to ensure consistency and fairness in their evaluation. They may also need to cross-reference different parts of the answer sheet to award correct marks for interconnected concepts or multi-step problems. Just like above, even this task is extremely tedious when performed for numerous students and can take days to complete which might lead to delay in result generation.

💡How AI Can Assist to overcome these shortcomings?
