3. …collects data in order to answer questions about the current status of the subject or topic of study sample …uses formal instruments to study preferences, attitudes, practices, concerns, or interests of a sample DESCRIPTIVE RESEARCH (“SURVEY RESEARCH”)

4. Detailed descriptions of specific situation(s) using interviews, observations, document review How do people implement this program? What challenges do people face? What are people’s perceptions? Did the program cause any changes in participants’ outcomes? Descriptive-Qualitative (Ethnography/ Case Study) You describe things as they are.

5. Descriptive-Quantitative Numerical descriptions (frequency, average) How many people are participating in this program? What are the characteristics of people in this program? How well did participants in this program do? Did the program cause any changes in participants’ outcomes? Why did the program work this way? You measure things as they are.

6. The basic steps of conducting a descriptive research... selecting an appropriate sample of participants collecting valid and reliable data reporting conclusions recognizing and identifying a topic to be studied

7. Step 1: Statement of the problem 1. Do teachers hold favorable attitudes toward using computers in schools? 2. What is the best way to provide access to computer equipment in schools? 3. What is generally the word-formation process utilized in the formation of text- message registers? Descriptive Research

8. Step 2: Identification of information needed to solve the problem
