True/false, matching, and fill-in the blank are all forms of ________ testing.

Written testing encompasses various formats that evaluate a student's knowledge and understanding of a subject. True/false, matching, and fill-in-the-blank questions are classic examples of written assessments, where responses are typically recorded in text format. These types of questions are designed to assess comprehension, recall, and the ability to apply knowledge in a straightforward manner.

In contrast, oral testing would involve spoken responses and may not lend itself to the same structured format as written assessments. Physical testing relates to assessments of physical skills and abilities, such as in physical education or certain vocational training, which does not apply to the question at hand. Visual testing would pertain to assessments designed to measure understanding through visual means, which also does not encompass the question formats described. Therefore, the identification of written testing as the correct answer accurately reflects the nature of the question types listed.
