Abstract

The aim of the work is to present an alternative approach to recording and evaluating student performance that enables sustainable performance recording with the possibility of integrating practical components in particular. The intended result is a digital portfolio with work samples - and not just certificates, which can be understood as a portfolio examination in the context of academic assessment. This is more about the recording, evaluation and certification of learning progress and competencies than the selective evaluation of a performance review, as is the case today, for example, with the submission of final theses. The idea is to expand and later replace final papers and performance tests, particularly in higher semesters, and instead introduce electronically recorded portfolio examinations - based on the example of teaching projects. Technologically, the approach is based on blockchain and wallets/repositories and, in the broadest sense, on an implementation of smart contracts. The technological approach of smart contracts enables a high degree of traceability and transparency with little administrative effort. It also offers secure certification of services by the provider. It should be clearly stated that neither the portfolio examination nor the administration of academic achievements with smart contracts is the original idea, but rather the change in the recording of academic achievements towards an alternative approach to the recording and evaluation of student performance, which enables sustainable performance recording with the possibility of integrating practical components in particular. The desired result is a digital portfolio with work samples. The primary aim of this idea sketch is to develop an individualized performance record for students, which can also contribute to making performance more transparent and comprehensible.
