Neuroscientists have revealed that the most of our learning is implicit. In light of this revelation, we as educators have to help learners to make their implicit learning explicit by appropriate instructional strategies. Further, by conducting an assessment with open-ended questions, mainly as recognition tests, learners’ implicit learning can be appropriately evaluated; that is, we are assessing learners’ higher-order thinking/learning.
