Correlation between teaching evaluation and learning

Grade points average (GPA), is an assessment tool used to evaluate student's academic achievement. It relates acquired percentages into letter grades that are later converted into numerical values. Different systems of assigning GPAs are being followed worldwide. Over the period of time, grades not conforming to student's academic standing has been reported as a serious concern. Researchers have identified the factors that result in grade inflation and proposed different schemes to address the problem. This paper evaluates the impact of higher-class average percentage score on the grade awards. Higher percentage scores are associated with higher student aptitude influencing instructor's decision towards inflated evaluation. In this work, original students' grades for different batches with different class average percentage scores were normalised based on published and proposed normalisation schemes. The outcomes were analysed, which revealed that the proposed scheme effectively addresses the issue of inflated evaluation.
