‘Learning Outcomes Depreciation’ to Solve Knowledge Timeliness in Lifelong Education

In the learning outcomes accumulation and exchange system, learners can get academic certificates or professional qualification certificates, by exchanging learning outcomes they hold. At present, the learning outcomes is lifetime effective in the credit bank. It causes a contradiction between renewal and lifetime effective of knowledge and skills. If learners apply an academic certificate by using the learning outcomes obtained a long time ago, the knowledge and skills mastered by the learners maybe do not match the current discipline development and vocational skills requirements. In view of the above contradiction, `learning outcomes depreciation' and its application is proposed. The specific method is adding a `learning outcomes depreciation coefficient digit' on the learning outcomes ID in the credit bank system. When exchange outcomes to certificates, judge whether the outcomes are effective by the `learning outcomes depreciation coefficient digit', and expired outcomes cannot be exchanged. The depreciation mentioned above can avoid outdated knowledge and skills of learners who getting certificates, and promote fair educational results.
