1) Front end evaluation is conducted at the beginning of the exhibit design process to understand the audience. It identifies what the audience knows, any misconceptions, and how they want to learn through methods like surveys, interviews, and focus groups.
2) There are three main types of evaluation: front end, formative, and summative. Front end evaluation identifies the audience needs. Formative evaluation occurs during design to test prototypes. Summative evaluation measures the exhibit's effectiveness after completion.
3) Front end evaluation guides the interpretation and content design by understanding what the audience already knows, attitudes, interests, preferred learning styles, and vocabulary to ensure the exhibit effectively reaches the audience.
