{"abstract":"This study aimed to evaluate the learning activity sheets (LAS) in English, which served as inputs for an action plan for the school year 2023-2024. Based on the result of the study, the English expert respondents obtained an overall weighted mean of 3.64 with the verbal interpretation of Strongly Agree, while the teacher-respondents got an overall weighted mean of 3.72, which is also verbally interpreted as Strongly Agree. There is no significant difference between the two groups of respondents' evaluations regarding the appropriateness, accuracy, usefulness, clarity, and comprehensibility on the developed learning activity sheets.","abstract_source":"original","authors":["Jerome Corporal","Melchor Espiritu"],"date":"2024-11-03","doi":"10.5281/zenodo.14027664","id":3906,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"061d7b627e034a95154d01868135ab9c251264b42cd82ec4a5aef3bba1f09598","schema":"scimatic-article/1","title":"Loss and Gaps: Evaluation of Learning Activity Sheets","volume":27}
