Which method is used to assess changes in knowledge through pretesting and post-testing?

The correct method for assessing changes in knowledge through pretesting and post-testing is assessment. An assessment involves measuring an individual's knowledge, skills, or competencies before and after an instructional period to determine the effectiveness of the training or educational intervention.

In this context, pretesting establishes a baseline of knowledge, while post-testing evaluates knowledge gained after the instruction. This method effectively demonstrates how much the learner has improved and highlights the strengths and weaknesses of the educational material.

The other methods mentioned do not specifically relate to evaluating changes in knowledge through testing. Skills tests typically focus on practical or applied abilities rather than knowledge retention. Surveys are often used to gather subjective feedback and opinions rather than objective measures of knowledge. Evaluation encompasses a broader analysis of programs or curriculum effectiveness and might not directly relate to testing in this specific context.
