論文名詞解釋

Rasch model：

Rasch models are used for analysing data from assessments to measure variables such as abilities, attitudes, and personality traits. For example, they may be used to estimate a student's reading ability from answers to questions on a reading assessment, or the extremity of a person's attitude to capital punishment from responses on a questionnaire.
Rasch models are particularly used in psychometrics, the field concerned with the theory and technique of psychological and educational measurement. In addition, they are increasingly being used in other areas, including the health profession and market research because of their general applicability.
The mathematical theory underlying Rasch models is in some respects the same as item response theory. However, proponents of Rasch models argue it has a specific property that provides a criterion for successful measurement. Application of the models provides diagnostic information regarding how well the criterion is met. Application of the models can also provide information about how well items or questions on assessments work to measure the ability or trait.

 
Likert type scale： 
A Likert scale (pronounced /ˈlɪkərt/, also /ˈlaɪkərt/), or more accurately a Likert-type scale, is a psychometric scale commonly used in questionnaires, and is the most widely used scale in survey research, such that the term is often used interchangeably with rating scale even though the two are not synonymous. When responding to a Likert questionnaire item, respondents specify their level of agreement or disagreement on a symmetric agree-disagree scale for a series of statements. Thus the scale captures the intensity of their feelings.The scale is named after its inventor, psychologist Rensis Likert.
