True experiments involve the manipulation of one or more More specifically, a research design refers to the type of study that will be conducted, whether it will be pre-experimental, quasi-experimental, or true experimental. True experimental design is regarded as the most accurate form of experimental research, in that it tries to prove or disprove a hypothesis mathematically, with statistical analysis. By experi­ ment we refer to that portion of research in which variables are manipulated and their effects upon other variables observed. gov working memory will function as a moderating variable in the design. 1 Pre-test Post-test Control Group Design In the event that the pretest is used to match groups, this design becomes the matching-only pretest-posttest control group design (see page 275), a much more effective design.

Despite scholars critiquing the quality of mobile learning research, there is an obvious lack of quantitative studies exploring the design quality of experimental studies of mobile learning as well as tools for self-checking and improving experimental design. It defines true experimental designs as having control over extraneous variables, a control group, a manipulable independent variable, and random assignment. Experimental unit: For conducting an experiment, the experimental material is divided into smaller parts and each part is referred to as an experimental unit.
