Which term refers to the code used by students to highlight personal passages in a text?

The term that refers to the code used by students to highlight personal passages in a text is best identified as "T-S," which stands for "Text-to-Self." This strategy involves students relating the content of a text to their own experiences or personal insights. By using this code, students can mark passages that resonate with them personally, facilitating deeper engagement and understanding of the text.

In educational contexts, these kinds of codes help students develop critical thinking and reflective reading skills by actively connecting the material to their own lives. This technique encourages personal investment in reading, as students are more likely to remember and comprehend material that has personal significance.

The other options, while related to various reading strategies or tools, do not specifically pertain to the practice of coding personal passages in a text. For instance, "Survey" and "SQ3R" are approaches for reading comprehension but do not directly convey the notion of personal coding, while "Code" is too vague without context.
