Concept:
Factors affecting learning are divided into learner-centric factors and teacher/instructional factors. Instructional factors must directly influence the quality of information transfer and student engagement.
Step 1: Evaluating Teacher Competence.
The teacher’s Skills (A) (pedagogical ability) and Knowledge (B) (subject mastery) are primary factors because they dictate how well a concept is delivered and explained.
Step 2: Evaluating Instructional Aids.
The use of Support materials (D) (TLMs, technology, charts) provides the visual or tactile stimulation necessary for deeper understanding.
Step 3: Identifying Irrelevant Factors.
The Physical appearance (C) of the teacher and their Family conditions (E) are personal matters that do not fundamentally change the cognitive learning process of the student in the classroom.
