This document defines experimental research and outlines its key characteristics and procedures. Experimental research directly manipulates a variable to test cause-and-effect relationships. It involves a comparison between an experimental group and a control group, manipulation of the independent variable, and random assignment. There are two types of experimental designs - pre-experimental and true experimental. True experimental designs use randomization and controls for threats to internal validity. The procedures for conducting experimental research include determining the research problem, writing the background, formulating research questions, and stating the aims of the study.

- 1. EXPERIMENTAL RESEARCH By Norma Anggraeni Rahayu 6-D 102122137
- 2. DEFINITION According to Frankle, Jack R. And Norman E. Wallen., Experimental research is unique in two very important respects: It is the only type of research that directly attempts to influence a particular variable, and when properly applied, it is the best type for testing hypotheses about cause- and-effect relationships.
- 3. CHARACTERISTICS OF EXPERIMENTAL RESEARCH Comparison of Group An experiment usually involves two groups of subjects an experimental group and a control or comparison group. Manipulation of The Independent Variable In this characteristic, the researcher actively manipulates the independent variables. Randomization An important aspect of many experiments is the random assignment of subjects to groups.
- 4. KINDS OF EXPERIMENTAL RESEARCH According to Suharsimi, Arikunto (P.123) Campbell and Stanley divided the kinds of experimental research into two kinds, there are; Pre Experimental Design and True Experimental Design.
- 5. KINDS OF EXPERIMENTAL RESEARCH Pre-Experimental Design Designs that are “weak” do not have built-in controls for threats to internal validity. One-Shot Case Study The One-Group Pretest-Posttest Design The Static-Group Comparison The Static-Group Pretest-Posttest Design
- 6. KINDS OF EXPERIMENTAL RESEARCH True-Experimental Design The Randomized Posttest-Only Control Group Design The Randomized Pretest-Posttest Control Group Design The Randomized Solomon Four-Group Design Random Assignment with Matching
- 7. PROCEDURES According to Arikunto, Suharsimi, the way to make an experiment research are: 1. Determining the problem of research 2. Writing the research Background 3. Formulating the problems 4. Formulating the Aims of the Research
- 8. PROCEDURES Determining the problem of research Arikunto, Suharsimi says “memilih masalah penelitian adalah suatu langkah awal dari suatu kegiatan penelitian”. Writing the research Background It is important for the researcher to write the research background in their research. It makes clear that their research appropriate to realize. Formulating the problems In the experiment research, before the researcher starts his research, he has to start make a plan. Formulating the Aims of the Research The researchers have to formulate the aims of the research
