{"abstract":"This descriptive research aimed to determine the validity of the instructional module in Science, Technology, and Society (STS) course based on content, instructional, and technical quality. Results show that the learning material evaluated by the instructional materials review committee was rated excellent in terms of content quality, instructional quality, and technical quality. Further, results indicated that the developed instructional material is valid and can be utilized by the intended audience. Thus, utilization of the material through e-learning instruction using the learning management system is recommended. Further, the developed instructional material serves as a prototype in developing other resource materials that can be utilized in the new normal education. Research on the resource material implementation is highly encouraged to determine its effectiveness through LMS use.","abstract_source":"original","authors":["Eddie Manzano"],"date":"2023-02-16","doi":"10.5281/zenodo.7644662","id":1021,"issue":2,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"d0336c97987954606879ae1cceb1d8821c7ea85141f143da1176ee5b89d6d362","schema":"scimatic-article/1","title":"Validation of Instructional Module in Selected Topics in Science, Technology and Society (STS) Course","volume":7}
