Forming tests from questions with different theoretical and practical degree

The assessment process must meet certain requirements in order to be correct and real-based. Through this process, the assessor discovers the degree of knowledge of the taught notions. Various degrees of difficulty help the student to diversify the learning and to meet all certain types of exercises and problems. In the context of the development of technology, models of assessment diversified or were updated using technology means. This work shows a type of model of generating tests using questions with different degrees of difficulty, given a desired interval of difficulty. This model is based on an algorithm which uses genetic notions. This model has several domains of applicability, one of the main being assessment within education. Also, it consists in a structure of a future web application which will use technology-based means for the assessment of students and which will be described in detail in the work. © Springer International Publishing AG 2016.
