Investigation of Test Outcomes Supported by Graphs

Students' knowledge assessment has occupied the attention of many researches pertaining to different disciplines. Recent areas of interest in this regard include availability of preliminary skills and status of latest obtained knowledge, self- assessment, grading methods, tests, hints, help functions, etc. Involvement of smart technology in assessment processes is another important issue which rapidly gains popularity among students and lecturers. What seems to have received less attention in earlier studies is a way to establish whether apparent lack of knowledge is related to intrinsic or explicit terms and concepts. Application of selected graphs is put forward in this work in an attempt to increase the likelihood of an improved knowledge assessment.
