<p>CHAPTER 10 - NONEXPERIMENTAL AND QUASI-EXPERIMENTAL STRATEGIES: NONEQUIVALENT GROUP, PRE-POST, AND DEVELOPMENTAL DESIGNS</p><p>1. Students should be able to distinguish between the experimental, nonexperimental, and quasi- experimental research strategies. </p><p>2. Students should be able to identify the two basic categories of nonexperimental and quasi- experimental designs (i.e., nonequivalent group designs and pre-post designs) and describe each.</p><p>3. Students should be able to identify the three types of nonequivalent group designs (i.e., differential research, posttest only nonequivalent control group design, and the pretest-posttest nonequivalent control group design) and describe each. In addition, students should be able to identify of these designs which are nonexperimental and which are quasi-experimental designs.</p><p>4. Students should understand how assignment bias threatens the internal validity of nonequivalent group designs.</p><p>5. Students should understand how adding a pretest to the posttest only nonequivalent control group design helps minimize time-related threats to internal validity, but does not reduce the possibility of differential effects.</p><p>6. Students should be able to identify the four types of pre-post designs (i.e., one-group pretest-posttest design, time-series design, interrupted time-series design, and equivalent time-samples design) and describe each. In addition, students should be able to identify of these designs which are non- experimental and which are quasi-experimental designs.</p><p>7. Students should understand how factors related to the passage of time threaten the internal validity of pre-post designs.</p><p>8. Students should be able to identify and describe the different types of developmental designs and understand each design’s strengths and weaknesses.</p>
