Abstract
The assessment reform which has enveloped every part of the world warrants an evaluation of teaching and learning practices through washback study. This is due to the fact that washback is the phenomenon of how testing influences the teaching and learning. Malaysia has adopted Outcome Based Education policy and therefore, the efficacy of its assessment system, Outcome Based Assessment, is deemed pivotal to be evaluated. Against this backdrop, the Washback on Learning Outcome Survey (WOLOS) was developed and validated by means of qualitative (semi-structured interview) and quantitative analysis (Item Objective Congruence) and Rasch Measurement Model). Responses to 150 items by 65 participants from one public university in Malaysia were subjected to the Rasch analysis to ascertain the psychometric properties of the WOLOS. Five criteria within reliability (person and item reliability), validity (separation index, item polarity and item fit) and precision of measurement were evaluated to ensure the usefulness of measurement in WOLOS. Some items were deleted. Subsequently, reanalysis of the criteria provided evidence that WOLOS can be considered a psychometrically reliable instrument for the evaluation of impact of assessment practices on student learning outcomes.
Highlights
Educational reform has enveloped the world with the intention to enhance educational quality
This study suggests that four aspects of student learning experiences are important when washback studies on courses or programs that are Outcome Based Assessment (OBA) based are conducted
Student conception of the importance of learning, student experiences in their in-class learning, student experiences in their out-of-class learning and student learning experiences based on specified outcomes make up the four important aspects of impact of assessment on learning
Summary
Educational reform has enveloped the world with the intention to enhance educational quality. WOLOS was developed to align with the intended outcomes of the Integrated Language Skills III course offered at University Teknologi Mara Malaysia (UiTM), this survey is adaptable to any OBA context in higher education or teacher education programs. This instrument has gone through a robust validation through the Rasch Model analysis, its utility as an instrument which measures impact on the intended outcomes of the course and washback is deemed efficient
