{"abstract":"Innovations, updates, and new ideas in teaching and learning are continuing to increase. Among these innovations is the use of video presentations as a classroom instruction. This strategy is commonly used by the teachers as an indicator of their integration of technology to education. This study analyzes the perception of teachers on the effectiveness of video presentation as an alternative to traditional method of teaching. The researchers used simple random sampling technique among the teachers in one of the elementary schools in Quezon City, in representing a group in an unbiased manner. This study is a quantitative method using descriptive correlational approach in determining the level of effectiveness of video presentation when used as a classroom instruction and in determining the significant difference when grouped according to profile. The method used is the most suited technique in coming up with the findings of this study. The outcome of this research provides that the respondents perceived that video presentation is an effective tool for them in teaching in terms of usefulness, motivation, performance, and assessment. The result motivated the researchers in conducting similar study using different research method and participants in identifying the effectiveness.","abstract_source":"original","authors":["Jhoanna Marrie Parvian","Juliefer Fernando","Elainee Tang-Zapata"],"date":"2023-07-15","doi":"10.5281/zenodo.8149013","id":1639,"issue":8,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"8335df42a195fc5c8d8535be460f529848505e8d9b133caaeadc49a83f618c02","schema":"scimatic-article/1","title":"Effectiveness of Video Presentation as a Classroom Instructional Tool in Teaching Elementary Students","volume":10}
