7.2. Open-ended questions/ subjective assessment questions

Open-ended questions allow learners to answer in their own words, offering a broader and more detailed response rather than choosing from predetermined options. They require more elaborate answers, encouraging students to think critically, explain reasoning, express opinions, or demonstrate deeper understanding. The number of answers for an open-ended question is not limited because it varies from one learner to the other and it depends on the question asked. Open-ended questions are recommended:

• To carry out a quick assessment as teaching is going on.
• To assess complex and difficult learning which needs to be summarized.
• To assess a portion of a wide course which needs to be summarized.
• To assess the learning objectives with high taxonomic level.

Open-ended questions are essential for assessing higher thinking skills, allowing learners to demonstrate not only what they know but also how they think and communicate. There are two types of open-ended questions: short answers and long answers questions.

A.    Short-answer questions

Short-answer questions require students to provide brief, concise responses, typically ranging from a word or phrase to a few sentences. These questions are designed to assess the recall of facts, understanding of key concepts, or ability to summarize ideas without the need for extended writing. Examples: What is photosynthesis? What is the capital city of Rwanda? Name two causes of environmental degradation.

Fill-in-the-blank questions are also a type of short answer question: Students complete a sentence or statement with the correct word or phrase. Example: The capital of Rwanda is ..

B.    Long answer questions

They require long answers often formulated as follows: What do you think about...? Tell me about...? Discuss...; What is your opinion about...? etc.

      Types of long answer questions

• Essay questions: Students provide a detailed, structured written response to a question, typically involving analysis, interpretation, or argumentation. They test deep understanding, critical thinking, and the ability to communicate complex ideas. They allow for in-depth exploration of topics; evaluates higher-order thinking. Example: Discuss the impact of climate change on global agriculture and propose potential solutions. Answer: (Student’s detailed, well- organized response).
• Problem-solving questions: Students are asked to solve a practical problem or a scenario using knowledge, reasoning, calculation, etc. and ask the respondent to propose a solution. They test creativity, critical thinking, and problem-solving abilities. These questions assess the ability to apply concepts to real-world situations. They test application of knowledge in practical contexts. Example: If a car travels 60 km per hour for 3 hours, how far does it travel? (Answer: the student does calculations and provides the answer).
• Performance-based questions: Students demonstrate their knowledge and skills through a task or activity rather than through traditional written responses. The questions assess practical application, creativity, and skills in action. They are more authentic and reflective of real-world tasks. Example: Perform a science experiment to test the reaction between baking soda and vinegar and explain the results. Answer: (Student demonstrates and explains the experiment results).
• Case study questions: Students analyze a specific situation, problem, or case and provide a response based on their understanding of the material. These questions assess critical thinking, problem-solving, and application of knowledge. They encourage deep analysis and the application of concepts to real-world scenarios. Example: Given a case study on a business facing financial challenges, suggest strategies for improving its financial position. Answer: (Student provides a detailed response with analysis).
• Diagram or labeling questions: Students are given a diagram (e.g., body part, machine, or process) and asked to label parts or describe components. They assess recognition, recall, and understanding of visual concepts. They are useful for subjects like biology, engineering, or geography. Example: Label the parts of the plant in the diagram (Labels might include root, stem, leaf, etc.).

 Disadvantages of open-ended questions

• Time-consuming to answer: Open-ended questions often require lengthy, detailed responses, which can be challenging for students under time constraints during tests or exams.
• Difficult to mark objectively: Scoring open-ended responses can be subjective and inconsistent, especially if clear rubrics are not used. This may lead to bias or variation in grading.
• They are not always easy to mark, since student responses may vary widely in depth, organization, and interpretation. This requires the teacher to develop clear marking criteria or rubrics to ensure fairness and consistency in evaluation
• Require strong language skills: Students with limited writing or language proficiency may struggle to express their understanding effectively, even if they know the content well.
• Increased teacher workload: Evaluating open-ended answers takes significantly more time and effort compared to marking closed-ended or multiple-choice questions.
• Risk of off-topic responses: Without clear guidance, students may misinterpret the question or provide responses that stray from the intended focus, making it harder to assess learning accurately.
• May discourage some learners: Some students may feel overwhelmed or anxious when faced with open-ended tasks, particularly if they lack confidence in their ability to structure responses.
• Limited use in large-scale testing: In standardized or large-scale assessments, open-ended questions are less practical due to the time and resources required for grading.
• It is not easy to set the marking scheme
• The validity of the contents can be neglected since the number of questions is very limited.
