Predicting Students' Performance on Agricultural Science Examination from Forecast Grades

The Botswana Examination Council (BEC) uses forecast grades obtained from secondary school Agriculture teachers to review component 2 of Agriculture final examination. Moderation of component 2 can help to improve candidates' final grade. This descriptive-correlational study purports to determine which of the component 1 (multiple choice), component 2 (structured questions), and component 3 (course work) of the BGCSE (Botswana General Certificate of Secondary Education) agriculture can be used to predict students' forecast grades. Examination scores spanning seven years (2001-2007), were obtained from BEC records. Two senior secondary schools were randomly selected from each of the five educational regions in Botswana, and then a systematic random sample of candidates with their respective scores was obtained from each of the selected schools. A multiple regression analysis was conducted using a backward procedure and it revealed that all the components 1, 2 and 3 significantly predicted forecast grades. Components 2 shared the largest (31.6%) variability with forecast scores. It was recommended that teachers should use composite scores from different school-based assessments to determine forecast grades. (Contains 4 tables and 2 figures.)
