One of the important tasks in scientific research in the field of learning is to define the relationship because there is not a result of the facts and the laws of reason-result relationship. Many symptoms of this and every so often found in education. In the world of education can cause the symptoms that occur as a result of that relationship in the field of science research is often called the research experiments (Experimental Research). In the field of learning in addition to this type of research there are other types of research, among others, the action research class (classroom action research), descriptive research and qualitative research.
A teacher in the face a problem in the field not only want to attempt to overcome the problem through action research class (PTK), was begun to develop at this time that the teachers want to do the experiment you want to apply a mtode / specific approach in the effort to learn memperbaki results for students who are diasuhnya. The teachers after getting education and training you want to apply / how to make an attempt to teach a new method didapatnya is more effective when compared with the methods of teaching during this dikenalnya to improve learning outcomes in subjects diampunya .. Therefore, based on the Training that they want to try using the research approach. But what type of research that has not exactly mastered many of the teachers, the knowledge needed to be able to adequately perform well. If a teacher already thinking towards the activities mentioned above, shows that they have to think scientifically
perform an activity. Type of research approach is most appropriate for teachers merealisasi activities is through research ekperimen.
Based on this general purpose of the research experiment is to examine the influence of a particular treatment of the symptoms of a particular group compared with other groups that use a different treatment. In education, for example, an experiment intended to assess / demonstrate the treatment effect of education (learning method with the problem solution) to the study of mathematics achievement in high school students or to test the hypothetical case of no treatment effect when compared with the method of understanding the concept. Action in the experiment referred to treatment, and defined as any action or any variation of conditions to be considered / known influence. Medium is the rate is not limited to measure or to describe the influence of treatment on the dicobakan but also want to test how the level signifikansinya (kebermaknaan or not mean) the influence of these groups when compared with the same but are given different treatment.
To conduct a good experiment, we first need to understand that all things related to the component experiment. Whether in relation to patterns experiment (experimental design), the determination of experimental and control groups, how the condition of both groups before the experiment was conducted, error-error that can affect veriabel treatment, statistical analysis techniques that are used depending on the right of each pattern that will be used, and what conditions should be in the implementation of the experiment. This is all necessary to be conducted primarily for researchers / teachers who want to write a research paper scientific experiment.
