Students’ performance evaluation for secondary school in Mbulu district using mean and dispersion charts grade and fixed grading method

Abstract

This article focuses on comparing the evaluation of students’ performance using the Mean and dispersion chart grade and fixed grading method. This quantitative study was conducted in Mbulu district council. The assessment of students’ performance is one of the challenges that face assessors in secondary schools. This quantitative study investigated students’ performance by comparing their performance using statistical quality control charts grade and fixed grading method. The study used secondary data collected from 240 sampled documents obtained from academic students’ progressive reports from six ordinary secondary schools in the Mbulu District. The students’ performance is analyzed by using statistical quality control charts grade and fixed grading method. The findings revealed that in the Mean and S chart grade method, a large number of students performed well than in the fixed grading method. The mean and S chart grade method was better than fixed grading in evaluating students’ performance since it lowers the cut-off point of the individual students’ performance. The finding has implications for evaluating students’ performance because secondary school teachers can use mean and S chart grades to raise individual students’ performance in each subject.
