Hey, math fans! Today, let’s dive into a debate that’s been sparking many discussions (especially now with our new Level 1 NCEA) – open book assessments versus rote memorisation for mathematics skills. Each method has its proponents and critics, and both offer unique advantages and challenges. Whether you’re a student wondering which approach will serve you best, or a teacher considering how to structure your exams, I wanted to share my experience so far.
Open book assessments allow students to use their textbooks, notes, and other resources during an exam. This approach shifts the focus from memorising formulas and theorems to understanding concepts and applying knowledge to solve problems.
Rote memorisation involves committing information to memory through repetition. In mathematics, this often means memorising formulas, theorems, and procedures without necessarily understanding the underlying concepts.
Advantages and Disadvantages Open Book Assessments
| ADVANTAGES | DISADVANTAGES |
| Reduces test anxiety. When students know that they can refer to their notes or practice assessments, this can significantly reduce test anxiety. Reflects real-world situations. In most professions, we don’t have to rely solely on memory to solve problems. In fact, in most jobs you would be encouraged to do research or “google it” to ensure accuracy. Many teachers would argue that we should be preparing students for the world. Encourages Better Study Habits Since students know they can access their notes, they are more likely to focus on organizing and understanding their study materials. This can lead to improved study habits and a better grasp of the topics. | Creates a false sense of security. Some students might assume that they don’t need to study as much (or at all) because they can use their notes during the test. This can lead to lower performance due to insufficient preparation. Time Management Open book exams require excellent time management skills. Students need to know their materials well enough to quickly find information, which can be challenging under timed conditions. If students do not have solid study habits or organizational skills, this could be a challenge. |
Advantages and Disadvantages of Rote Memorisation
| ADVANTAGES | DISADVANTAGES |
| Building a good foundation. Formulas and procedures are essential skills in mathematics. By memorising skills and formulas, students have these important skills at their fingertips. Quick recall In timed exams, being able to recall information quickly without searching through notes can be a significant advantage. Preparation for competitive exams Many standardised tests and competitive examinations still rely heavily on memorisation. Familiarity with this approach can help students perform higher. | Learning without retention In some cases, students who use rote memorisation will memorise a skill without fully understanding it. This knowledge is often quickly forgotten after the exam. Increased anxiety The pressure to remember large amounts of information can cause test anxiety for some students or even lead to students forgetting the information they studied or memorised. Forgetting Rote memorisation does not encourage development of problem solving skills. |
How do we find a balance?
I personally don’t believe that the debate between open book assessments and rote memorisation has to be an either/or scenario. The most effective approach might involve a combination of both methods. There could be certain topics that lend themselves more to one side. Knowing your students and how they learn best is also important to consider.
What I have found most helpful is explicitly teaching study skills with my students. Many students enter high school not knowing how or even why they should take good notes.
