Final answer:
Developing evaluations on the basis of program theories has three advantages: providing useful and usable information, identifying replicable programs, and ensuring congruence with program efforts.
Step-by-step explanation:
Developing evaluations on the basis of program theories has three advantages:
- Useful and usable information: Program-based evaluations provide valuable information that can be used to improve the program. For example, evaluations can reveal students' preferences, identify areas for improvement, and suggest program modifications.
- Replicability: Program evaluations can identify successful programs that can be replicated in other settings. This helps in disseminating effective interventions and improving outcomes across different communities.
- Congruence with program efforts: Evaluations should align with the program's goals, complexity, length, and cost. Simple programs do not require complex evaluations, while longer and more complex programs may require more extensive evaluations.
