Pre-experimental Research Designs & It’s Uses Sani Prince Sarkar Research Scholar Department of Education Aligarh Muslim University, Aligarh

Research Design a crucial aspect of the research process encompasses the overall plan of the research work outlines structure and strategy employed to answer a research question or test a hypothesis. guides the collection, analysis, and interpretation of data. choice of research design depends on the nature of the research question, the type of data needed, and the researcher's goals

Experimental Research Design a study to test an idea, practice, or procedure to determine whether to affect the outcome or dependent variable. a systematic approach used in scientific research investigate cause-effect relationships between variables perform carefully in a controlled environment involves the intentional manipulation of one or more independent variables to observe their impact on a dependent

Experimental Research Design Characteristics Manipulation of Variables Control Group Cause-effect Relationship Randomization

Types of Experimental Design Pre-experimental Design True experimental Design Quasi-experimental Design

Pre-experimental Design simplest form of research design that follows the basic steps in the experiment does not have a comparison group considered as very weak in terms of control less control over the experiment includes one or more than one experimental group to be observed against certain treatments.

Types of Pre-experimental Design There are three types of Pre-experimental designs. One Shot Case Study Design One Group Pre-test Post-test Design Static Group Comparison Design

One Shot Case Study Design this design includes a single experimental group, on a single occasion after experiencing some event, treatment, or intervention observations are made after the implementation of that treatment no random assignment of the subjects to the experimental group no control group

One Group Pre-test Post-test Design the simplest type of pre-experimental design only the experimental group is selected as the study subjects a pre-test of the dependent variable is made before the implementation of the treatment in the selected group a fter treatment, a post-test is carried out to assess the effect of treatment on the group t his design measures the effect of intervention before (pre-test) and after the experiment (post-test) t here is no control group in this design

One Group Pre-test Post-test Design

Static Group Comparison Design two groups: Experimental G roup and Control Group no random selection of the participants the research er assumes the two groups are equivalent at the start n o pre-test; dependent variable measured after treatment p ost-test compares the effect of the independent or treatment variable b etter performance in the experimental group indicates the independent variable's responsibility for change in the dependent variable

Static Group Comparison Design

Uses of Pre-experimental Design This design is often the first step in the research process and can provide valuable insights that inform future studies. Exploratory Studies: exploring a new area of study or phenomenon Pilot Studies: to test the feasibility before conducting larger, more rigorous experiments Preliminary Investigations : investigations between variables to provide initial evidence for the presence or absence of relationships One-Shot Case Study: provide preliminary evidence of the potential effects of an intervention

Contd … One-Group Pretest-Posttest Design : examine changes within the group over time Time-Series Designs : provide insights into how outcomes change over time by measuring the dependent variable at multiple time points before and after the introduction of an intervention Feasibility Studies : assess whether a larger-scale experimental study is practical and achievable given the available resources and constraints Educational Research : evaluate the effectiveness of teaching methods, interventions, or programs in real-world settings
