The analysis revealed that students received lower grades due to attending lectures online, indicating that online courses were less effective in imparting knowledge compared to traditional in-person lectures. This might be because in virtual settings, students engage with the material in a more detached manner. From my experience, the interaction in a physical classroom involves real-time, reciprocal engagement between teachers and students, enhancing learning outcomes. Conversely, in virtual environments, students might merely be present without actively participating in the learning process, resulting in a more passive experience that resembles observation rather than active involvement. In contrast, physical settings tend to foster greater activity and engagement, making students feel more integral and less like mere digital profiles.

EL punto fundamental con las materias del area de ciencias ,es que las partes teoricas de dichas asignaturas , derivan en un tipo de contenido de orden practico. es decir todo analisis conceptual en el campo de las ciencias es un reflejo de lo que se demostrara en una practica de laboratorio. las plataformas en linea son un elemento de ayuda, pero para el conocimiento en el campo de las ciencias tienen sus limitaciones.

Anita Z Goldschmied Thank you, I agree with every word in your post. Especially with "If anything, experience dictates that theory should be the part that can be taught online effectively, depending on the subject and some other factors, a few listed above." Yes, this is my own experience too. So I try to combine online (80%) with face-to-face (20%) when teaching.

On line teaching is to a large extent Good for teaching the theory parts of science subject. But, one can not undermine the power or efficiency of face-to-face contact as far as sciences is concerned, there are intricate parts of it (even if its theory) that needs direct or face-to-face illustrations for easy assimilation by the learner (students).
