Description

In the academic world is very common to evaluate teacher`s performance in class with the use of questionnaires fill up by students. In general, the analysts use statistical descriptive analysis to obtain information from surveys that evaluate teachers? performance in class. Most analyses consider students? opinion as the basis to generate recommendations to teachers for improving their classes. In this thesis, we considered necessary to add to the analysis of the students? opinion, the judgments and expertise of the evaluated teacher and other colleagues? experiences shared at the same university. To accomplish this, we propose to obtain common patterns in the form of association rules. These common patterns represent the teacher`s model. With these patterns we constructed a graphical representation that includes patterns considered good by the students and good by the teachers. The graphical representation was constructed using rules evaluated with objective and subjective measurements and a data mining methodology. Hence, to evaluate other rules that were not initially taken into account inside the representation, we constructed a semantic measure that considers students?, teachers', and colleagues? opinions along with a variable that measures the effort to improve specific attributes in the rule. This utility semantic measure provided a value that recommended the application of a specific pattern. This measure helped identify the best attributes teacher should keep working on and which were the weakest ones where he needed to boost. Finally, to discover new topics that are not considered in the students? survey we apply topic modeling to identify the different relevant topics that teachers talked about during the interviews. The results obtained from this work revealed that feelings and communication were components that strongly affected learning and critical thinking of students. Therefore, they should be considered as key elements in the design and construction of the course and as part of the improved survey questions. We concluded that the addition of subjective analysis and utility semantic measure improved the efficacy of the tools used to enhance teacher?s performance.
