In the ever-evolving landscape of education, technology continues to play a crucial role in improving teaching and learning processes. One area where technology, particularly artificial intelligence (AI), is making significant strides is in e-marking systems for essay and short answer questions.
However, with the integration of AI into these systems, it’s essential to understand the advancements, ethical considerations, and the balance between AI and human expertise to ensure accuracy and fairness.

Key Advancements in AI for E-Marking
Before diving into the advancements in AI technology for e-marking systems, it’s crucial to differentiate between the two main types of AI in the ecosystem: classification and generative AI. Classification AI has been around longer and has seen significant improvements, making it more suitable for marking due to its reliability and explainability. On the other hand, generative AI, while popular and attention-grabbing (think ChatGPT), poses risks due to its susceptibility to bias, lack of explainability, and tendency to hallucinate.
Graide leverages the latest advancements in classification AI to offer a robust e-marking solution. Recent improvements involve techniques that move away from the “black box” nature of traditional neural networks, introducing explainability and reducing the volume of data required to train models. These advancements make Graide more useful for educators at all levels, transforming marking from a reading and grading process to a review-focused task. This shift not only speeds up the marking process but also significantly reduces the workload for educators, allowing them to focus more on delivering quality instruction.
Balancing AI-Driven Marking Systems with Human Expertise
Balancing AI-driven marking systems with human expertise is crucial to ensuring accuracy and fairness in assessing student responses. The context of the assessment—whether it’s summative or formative—plays a significant role in determining this balance. Summative assessments, which have high stakes and significant implications for students’ futures, require a higher level of human intervention.
AI can assist in the initial marking, but a robust human review system must be in place to ensure the final assessments are fair and accurate.
In formative assessments, where the stakes are lower, AI can take on a more significant role, allowing teachers to focus on personalised instruction and support. If the AI models are proven to be accurate, human intervention can be minimised, making the process more efficient while still providing valuable feedback to students. Graide’s platform is designed to adapt to these varying needs, empowering educators to provide the best possible learning experiences while maintaining high standards of accuracy and fairness.
Ethical Concerns and Mitigation Strategies
The integration of AI in e-marking systems brings several ethical concerns, including bias, lack of explainability, and unequal access to technology. Bias occurs when the datasets used to train AI models are skewed, leading the models to propagate these biases. To mitigate this, it’s essential to ensure the data labelling is broad and clear, incorporating secondary labels to find ancillary correlations.
Graide addresses the lack of explainability by creating bespoke models for specific components of evaluation and using a secondary model to infer results from the first set. This layered approach helps improve the transparency and reliability of AI assessments.
Unequal access to technology, primarily due to financial and class divides, is a significant barrier. Addressing this issue requires governmental initiatives to ensure that schools in lower-income areas have the necessary technological infrastructure to benefit from AI-driven assessment tools.
Enhancing Reliability and Consistency of Exam Results
AI-driven assessment technologies can significantly enhance the reliability and consistency of exam results. One effective approach is using AI as a rapid moderation tool. AI models can quickly identify outliers, allowing for a 100% sampling in moderation. This targeted moderation focuses on the outliers that do not fit the rest of the model, improving the effectiveness and reliability of the moderation process.
Graide’s AI-driven platform continuously improves by incorporating feedback and performance data, ensuring that the models remain accurate and effective over time. This ongoing refinement process helps maintain the integrity of the assessment system, providing reliable and consistent results that educators and learners can trust.
Conclusion
In the fast-paced world of vocational education, the integration of AI in e-marking systems is transforming the way assessments are conducted. By leveraging advancements in classification AI, balancing AI with human expertise, addressing ethical concerns, and using AI for fast moderation, we can create a more efficient, fair, and reliable assessment system.
Graide’s AI-powered platform stands at the forefront of this transformation, supporting instructors, empowering learners, and revolutionising the education landscape. Embrace the future of education with Graide, and empower your instructors and learners to reach their full potential.
