Quality of a Single Subject Research Study

Single Subject Research

Single subject research is a precise, systematic method utilized to describe essential philosophies of conduct and institute verification based way of operation or behavior. A productive and long narration is present in which the single subject study has given helpful entropy for special education's field (Horner, Carr, Halle, & Wolery, 2005).

This type of study has proven especially applicable for significant practices in education at the individual learner's level. Instead of descriptive or co-relational, single subject research is experimental and its rationale is to record in detail fundamental or practical associations between dependent and independent variables. The research of single subject study uses within & among matters in contrast to manage for significant threats to internal legality & needs methodical duplication to improve external legality.

Description of participants and settings

Functional depiction of the participants, settings, and the procedure of participants' selection is required by the single subject research study. Participants are portrayed in enough detail to permit others to choose individuals with same characteristics.

Studies are required to improve on the description and identification process of participants, particularly given the variability of attributes connected with ASD and the issue of applicability/utility of findings of research for experts.

Global description of setting for example, distinguishing participants as having developing impairments would be inadequate. Therefore, the process and specific instrument need to be determined (Horner, Carr, Halle, & Wolery, 2005).

Dependent variable

Dependent variables are defined functionally as to permit (a) reliable and valid evaluation of the variable & (b) duplication of the procedure of appraisal. Dependent variables are those that permit undeviating examination and experimental synopsis.

The repeated procedure of measurement of individuals conduct is significant for comparing each participant's performance with his/her previous performance. Procedure of measurement of the actions of a person across stages or situations permits comparing patterns of performance under dissimilar environmental circumstances.

Dependent variables are precise and valid as it allows direct examination and experimental review, characterized to permit (a) variable's substantial and unwavering appraisal and (b) evaluation methodology's replication (Horner, Carr, Halle, & Wolery, 2005).

The repeated measurement is carried out of individual behaviors for comparing each participant's performance with his or her previous performance. Repeated measurement has allowed identification and comparison of patterns of performance.

Recording of dependent variable is evaluated for reliability all through the research by repeated observation of the agreement of interobserver. The measurement of ...
