What is Program Theory-Based Evaluation Design

This chapter employed Program Theory-Based Evaluation Design and Summative Evaluation Model to evaluate the merits and worth of National Open University of Nigeria (NOUN) from 2003 to 2013 as a distance education intervention. A sample of 902 was drawn from students of and staff of NOUN, National Universities Commission and conventional Federal Universities in Nigeria. Construct validated Program Theory-based Evaluation Questionnaire with reliability coefficient of 0.79 was used. Ten hypotheses were tested using ANOVA and independent samples t-test at 0.05 alpha. Results indicated that great discrepancy exists between the expected and actual outcomes of NOUN as it is significantly inadequate in addressing ‘higher education for all in need' intervention for which it was established. Though the objectives for which NOUN was established has been partially implemented as defined and aspects of its objectives achieved. The study recommends that the defected aspects of NOUN should be modified to meat stated objectives.
