Which factor should NOT be considered a likely contributor to Isabel's lack of math understanding?

When examining factors that may contribute to a student's lack of understanding in math, it's important to focus on elements that can directly influence a student's ability to grasp concepts. Gender, in this context, does not inherently affect a student's aptitude in mathematics.

Historical biases and societal perceptions have influenced the belief that there are gender differences in math ability; however, research demonstrates that when provided with equitable instruction and resources, students of any gender can perform equally well in math. The other factors listed, such as the methods of instruction, socioeconomic status (SES), and language barriers, are all well-documented influences on students' academic performance. They can significantly impact a student's learning experience and understanding of mathematical concepts, making them more relevant considerations in this scenario.

In summary, the lack of understanding in math is more closely related to instructional quality, access to resources, and individual circumstances rather than gender, making it a less relevant factor in this context.
