Adaptive learning exams have already been developed where the difficulty level of an exam is tailored according to the student performance during the exam. If a student attempts a "medium difficulty" question successfully, he/ she will be given a harder question to test him for the next level of knowledge. A traditional exam is a mix of mostly medium, some hard and some difficult questions and all students have to attempt the same number of question. Suppose an exam is made of 100 questions but in an adaptive learning exam, a student does 560 hard questions correctly, we have achieved the exam objective and student has performed good to excellent. While on the other hand, if a student has missed 50 easy questions, there is no point in testing more.
The next era of education will have blended models where core course objectives can be taught in the traditional environment and the rest can be adaptive learning.
Adaptive learning is a good tool for individual student progress and the cognitive understanding of the course objectives. The softwares will recognize what was missed by the student and can tailor to make another learning material or exam to teach/test those objectives that need to be learned.
