In addition, it was hypothesized that students who had a positive attitude towards learning with the aid of videos would perform better than students who had a neutral or negative attitude. The hypothesis of this study was that students’ scientific literacy would improve after implementing video-based POE within teaching, in the context of preparation of salts. Thus, the platform offers precious insight, and you can rearrange your stores or display the most attractive products.This study was carried out in order to investigate the impact of implementing video-based predict-observe-explain (POE) on students’ scientific literacy, particularly in chemistry’s concept of salts.
