Using AI for Auto-Marking of Assessment

Artificial intelligence (AI) has become a key player in various aspects of our lives, including the education industry. One intriguing application of AI is in the auto-marking of assessments. By leveraging the capabilities of AI, educators can save time and effort while ensuring that students receive accurate and precise feedback on their performance.

Auto-marking through AI provides a reliable, efficient, and impartial way to evaluate student submissions. This approach eliminates human error and bias from grading, resulting in objective and consistent student evaluation. Additionally, AI-assisted marking enables teachers to spend less time on administrative tasks and more on personalised teaching and student interaction.

With the continuous advancement in AI research, the potential for more sophisticated auto-marking algorithms is limitless. As educators increasingly explore these technologies, they lay the foundation for a more efficient and equitable learning environment.

AI-assisted grading – is this the future?

Understanding AI’s Role in Assessment

AI-powered systems can learn from data, meaning that they can be trained to understand specific marking criteria and effectively grade student work based on this understanding. Some popular applications of AI in assessment include:

  • Natural Language Processing (NLP): Utilised for evaluating language-based assignments such as essays or tests, AI can analyse the structure, coherence, and quality of a student’s response.
  • Multiple-choice question grading: AI can auto-mark multiple-choice tests, increasing the efficiency of the grading process and potentially reducing human error.
  • Plagiarism detection: By identifying patterns and text similarities, AI can effectively screen submissions for potential instances of plagiarism.

The benefits of using AI in assessment are numerous:

  • Increased efficiency: AI-powered systems can process large amounts of data much quicker than a human marker, providing students with faster feedback.
  • Reduced workload for educators: By automating the marking process, teachers can dedicate more time and energy to other aspects of teaching and learning.
  • Consistent and unbiased grading: AI can help to eliminate the subjectivity sometimes associated with human markers, ensuring that each student’s work is assessed fairly and consistently.

However, AI’s role in assessment also comes with some potential drawbacks:

  • Lack of human touch: While AI is effective at assessing responses by following pre-defined criteria, it cannot truly understand the nuances and complexities of human creative work, nor can it provide personalised feedback.
  • Potential biases in data: AI algorithms are only as unbiased and effective as the data they are trained on. As such, care must be taken to ensure the training data is accurate and representative of the desired assessment criteria.
  • Technical challenges: Implementing AI-assisted assessment may require a significant investment in infrastructure, training, and support for educators and students.

Integrating AI into the assessment process is a promising avenue for enhancing efficiency and reducing educator workload. However, attention must be given to addressing its limitations and ensuring that systems are accurate and fair.

Assessment in Foundation Phase Coding and Robotics

The CAPS Coding and Robotics curriculum was released a while back by the DBE. While still waiting for the final version to be signed off by Umalusi, many schools have already implemented it as a subject. I took a bash at explaining the assessment requirements below, providing some examples from material I’ve developed.

CAPS Foundation Phase Assessment Principles 

Let’s take one step back and look at the principles behind assessment at the Foundation Phase. According to the CAPS curriculum document, assessment is a continuous planned process involving four steps:

  • Generating and collecting evidence of achievement
  • Evaluating the evidence
  • Recording the findings
  • Using the information to understand and assist learner development

The CAPS curriculum emphasizes that assessment should include both informal (Assessment for Learning) and formal (Assessment of Learning) methods. Regular feedback should be provided to learners to enhance their learning experience.

AI and Assessment

I’m fascinated by how artificial intelligence (AI) revolutionises various aspects of life, and educational assessment is no exception. By incorporating AI into assessment processes, educational institutions can potentially benefit from enhanced accuracy and efficiency in evaluating and selecting candidates. With the integration of AI, assessment tasks can be generated, and student work automatically scored, significantly offloading tasks from the teacher to AI. But is this a good thing? Let’s look at this in more detail. 

AI has made significant advancements in recent years, and its applications in education are continually expanding. One of the areas where AI can make an impact is student assessment. AI-based assessment systems utilise machine learning algorithms and natural language processing to evaluate student performance. Two primary AI-based assessment methods are rules-based and machine learning-based assessments. Rules-based AI follows pre-defined criteria to evaluate performance, while machine learning-based AI adapts dynamically, learning from data and improving its accuracy over time. These systems can assess various skills, from knowledge recall to problem-solving and critical thinking abilities. By automating the evaluation process, AI can save time for educators and provide real-time feedback to students, allowing them to adjust their learning strategies accordingly.

AI in assessment offers numerous potential benefits, including:

  • Adaptive testing: AI can adjust the difficulty of assessment items based on a student’s performance, providing a tailored testing experience that accurately measures their abilities.
  • Automatic grading: Machine learning algorithms can evaluate open-ended responses, such as essays and short answers, reducing the workload for educators.
  • Objective scoring: AI helps maintain a consistent scoring standard, eliminating human bias and subjectivity from the evaluation process.
  • Data-driven insights: Assessment data collected by AI systems can be used to identify patterns and trends, allowing educators to make more informed decisions about their instruction.

However, implementing AI in assessment also raises some concerns, such as data privacy and the potential for algorithmic bias. To overcome these challenges, it is crucial to develop transparent and robust AI assessment systems that maintain the integrity of the evaluation process and protect student data.
