Using demonstrations in classroom predominantly involves learners in

The correct answer is visual and auditory learning.

Classroom demonstrations primarily involve two major sensory channels for learners:

1. Visual Learning: Students observe the teacher conducting the experiment, showing a process, or displaying objects and diagrams.

2. Auditory Learning: Students listen to the teacher's verbal explanations, instructions, and descriptions accompanying the visual demonstration.

Since learners are primarily watching and listening during a demonstration rather than performing hands-on physical manipulation themselves (which would involve kinesthetic learning), demonstration in a classroom predominantly engages visual and auditory learning modalities.
