Descriptive methods are used to collect data about the current state of a program or intervention, while evaluative methods are used to assess the impact of the program or intervention. This combination of methods allows researchers to gain a comprehensive understanding of a program or intervention and its effects.
Some of the key features of descriptive-evaluative research design include:
* It is a flexible approach that can be tailored to the specific needs of a research project.
* It can be used to collect both quantitative and qualitative data.
* It allows researchers to assess the effectiveness of a program or intervention in a real-world setting.
* It can be used to compare different programs or interventions to identify the most effective approach.
Here are some examples of descriptive-evaluative research design:
* A study that examines the effectiveness of a new teaching method by comparing the test scores of students who use the new method to the test scores of students who use a traditional teaching method.
* A study that evaluates the impact of a new public health campaign by measuring changes in the rates of disease incidence and mortality.
* A study that compares the effectiveness of two different types of job training programs by tracking the employment rates of participants in each program.
Descriptive-evaluative research design is a powerful tool that can be used to gain valuable insights into the effectiveness of programs and interventions. By combining descriptive and evaluative methods, researchers can obtain a comprehensive understanding of the impact of a program or intervention and identify the most effective approaches.
