Uploaded by McGucket

Economics achievement test (EAT) for assessing senior secondary two (SS2) achievement in economics was developed and validated. The study was guided by five research questions and involved SS2 economics learners for pilot testing and reliability checking, followed by try-out item analysis using a larger randomly drawn sample. Sixty-five percent of initial items were screened and retained based on difficulty and discrimination indices. Face and content validation used subject experts and test construction experts; reliability via Kuder–Richardson Formula 20 produced 0.81, indicating good quality, validity, and high reliability.

Five research questions guided the study. Twenty and 100 mid-senior secondary (SS2) economics students was used for the pilot testing and reliability check respectively. A sample of 250 students randomly drawn was used to subject initial 80 objective test items for the test try-out that yielded the data for item analysis. 50 items with difficulty indices ranged from 0.25 to 0.79 and discrimination indices of 0.20 to 0.58 where retained. Face and content validation of EAT was ensured by constructing items in line with the test blue print, the use of subject experts in SS2 economics and two experts in test construction. The test reliability established through Kuder- Richardson formula 20 gave a coefficient of 0.81. The test was found to be of good quality, valid and highly reliable. The EAT is therefore recommended for use in assessing SS2 students’ achievement in economics and to determine/predict students that will do well in economics in their final class (SS3) as well as those that will have good performance in economics external examinations (WAEC and NECO) .

FAQs

What was the main purpose of the Economics Achievement Test (EAT)?

To develop and validate an Economics achievement test for assessing SS2 students’ achievement in economics.

How was item quality determined during the test try-out?

Through item analysis using difficulty indices (0.25 to 0.79) and discrimination indices (0.20 to 0.58), retaining 50 items.

How reliable and valid was the EAT?

Face and content validation were ensured using SS2 economics subject experts and test construction experts, and reliability using KR-20 produced a coefficient of 0.81.
