Final answer:
The factor most linked to a negative self-concept for learning is Low self-esteem, as it affects one's sense of competence and worthiness across various areas, including education.
Step-by-step explanation:
The factor most strongly linked to a negative self-concept for learning is b) Low self-esteem. This is because self-esteem encompasses one's overall view of oneself, including competence and worthiness in various realms including education. A student with low self-esteem may struggle to believe in their ability to succeed academically, which can lead to negative expectations, avoidance of challenges, and a diminished sense of competence.
While high self-efficacy, intrinsic motivation, and positive teacher feedback can contribute positively to a student's self-concept, low self-esteem has a broader impact that can undermine these positive factors and contribute significantly to a negative self-concept.
