Are Your Exams Really Testing Knowledge? Uncover Hidden Flaws in Teacher-Made Tests
"Dive into a critical analysis of exam validity and cognitive assessment, revealing how to create fairer and more effective tests for academic success."
In Nigeria, there's growing concern about students not doing well on tests, especially big public ones. This makes people wonder if teachers are really preparing students well enough in the classroom. One important way teachers check how students are doing is through classroom tests. These tests give information that helps teachers know how well each student is learning. After the tests, the results are shared, and this feedback is helpful for students, their families, and the government, all of whom have a stake in education.
Classroom tests not only help to see where students stand but also let teachers know if they are likely to meet the goals for teaching a subject at a certain level. When these tests are done and results are out, everyone involved can look at how good their work was. Then, if needed, they can plan ways to help students improve or keep doing well.
One good thing about teacher-made tests is that teachers can pick their own words and set up the questions as they like, especially with multiple-choice questions. But because of this, there can be many different ways the questions are written, like how long the questions are, how many choices there are, and how clear the choices are. Also, some tests used in schools might not be checked well enough before they are used. So, it's important to look at how these tests are made and if they are really doing a good job of measuring what students know.
Unveiling the Layers of Learning: Cognitive Domains and Test Design

Bloom's Taxonomy splits learning into six levels that show how deeply someone understands what's being taught. These levels include remembering facts, understanding them, using them, breaking things down, putting them together in new ways, and judging their value. The first three levels—remembering, understanding, and using—are seen as simpler thinking skills. Most tests in primary and junior secondary schools should focus on these because students at this level are still learning how to think critically and abstractly. It wouldn't be right to ask them to do tasks that need more advanced thinking.
- Determine if the selected undergraduate tests accurately measure course content.
- Examine the distribution of test questions across Bloom's Taxonomy levels.
- Assess if the answer choices in the tests are reasonable and well-constructed.
Key Recommendations for Universities
Universities and similar institutions should create tests that align with the topics listed in the course content. It's also important to have more questions per course, aiming for between 70 and 100. This improves the test's reliability and better reflects the course's objectives. Additionally, including more questions that assess high-level thinking skills ensures that students who pass the courses can demonstrate a high level of proficiency.
