Which of the following is not true with respect to the learning of Mathematics? 

Options

A. Ability to perform and excel in Mathematics is innate
B. Teachers' beliefs about learners have powerful impact on learning outcomes
C. Students' socio-economic background impacts their performance in Mathematics
D. School's language of instruction can impact a child's performance in Mathematics

Answer

To solve the question "Which of the following is not true with respect to the learning of Mathematics?", we will follow these steps:

### Step 1: Understand the Question
We need to identify which statement regarding the learning of Mathematics is false. This involves analyzing the options provided in the question.

**Hint:** Look for statements that may imply that success in Mathematics is solely based on innate ability rather than practice or effort.

### Step 2: Analyze the Options
Let's consider the common beliefs about learning Mathematics:
- Mathematics requires rigorous practice.
- Success in Mathematics can be achieved through hard work and practice.
- Some people believe that the ability to excel in Mathematics is innate (i.e., you are born with it).

**Hint:** Think about whether skills in Mathematics can be developed or if they are fixed traits.

### Step 3: Identify the False Statement
From the analysis, we see that the statement "the ability to perform and excel in Mathematics is innate" suggests that only those born with a talent for Mathematics can succeed. This is a misconception.

**Hint:** Consider how many successful mathematicians emphasize the importance of practice and learning from mistakes.

### Step 4: Conclusion
The statement that is not true regarding the learning of Mathematics is that "the ability to perform and excel in Mathematics is innate." This implies that anyone can improve their mathematical skills through practice and effort.

**Final Answer:** The option that is not true is "the ability to perform and excel in Mathematics is innate."
