Not receiving regular health care is not a characteristic of socially disadvantaged students. This means that socially disadvantaged students do receive regular health care.

Explanation:

1. Experience child care practices that do not prepare them effectively for school:
One characteristic of socially disadvantaged students is that they often experience child care practices that do not adequately prepare them for school. This could include a lack of access to quality early childhood education programs or limited exposure to early literacy and numeracy activities. These factors can contribute to a readiness gap between socially disadvantaged students and their peers when they enter school.

2. Do not receive regular health care:
While access to regular health care is important for all students, it is not specifically a characteristic of socially disadvantaged students. Socially disadvantaged students may face barriers to accessing healthcare, such as limited financial resources or lack of health insurance coverage. However, it is not accurate to say that they do not receive regular health care as a characteristic.

3. Are not exposed to a wide variety of experiences:
Another characteristic of socially disadvantaged students is that they may have limited exposure to a wide variety of experiences. This can be due to factors such as limited access to cultural and recreational activities, lack of travel opportunities, or living in neighborhoods with limited resources and opportunities. The lack of diverse experiences can impact their overall development and ability to connect with the curriculum in school.

4. Are not motivated to do well in school:
It is incorrect to assume that socially disadvantaged students are not motivated to do well in school. Motivation can vary among individuals regardless of their social or economic background. While some socially disadvantaged students may face additional challenges or barriers to motivation, it is important to recognize that motivation is a complex and multifaceted aspect of individual behavior that cannot be generalized based on social disadvantage alone.

In conclusion, the characteristic that is not associated with socially disadvantaged students is not receiving regular health care. This does not mean that socially disadvantaged students do not face challenges in accessing healthcare, but rather that it is not a defining characteristic of their social disadvantage.
