construct

The purpose of the present study was to construct and normalization the pre-school students' learning disability test. A researcher-made visual-spatial test consists of seven sections (symbolization, space status, visual distinction, visual argumentation, visual memory sequence, maze, and rotational form) its content validity is confirmed by psychology professors and then was performed on a sample of 206 preschool students. The questions were analyzed, and their validity, reliability and cut point were determined. This test has enough reliability. To determine the validity of construct and composing component of the tests, the main component by rotation in Varimax normalized method was used. In analysis of the factors of questions in spatial perception subtest, seven of which were namable. Conformity factor analysis was also used to determine the validity of factors: the conformity factor analysis confirmed that the structure of questionnaire had an acceptable fitness to the data. independent t-test demonstrated that there is a significant difference between average scores of the students with learning disability and normal. To investigate convergent validity, we used the checklist of learning disability that simultaneously was completed by the mothers. The results of Chi-Squared test demonstrated that there is a significant relationship between these two variables, the completed checklist by mothers and completed learning disability test by children.

The term “ philosophy of research in applied linguistics” may be considered to cover a wide range of academically and philosophically important issues that have recently begun to capture the attention of scholars in research programs in their efforts, on the one hand, to reflect upon how they have traditionally approached their scientific practices and, on the other, to reconsider and redefine their research priorities in the light of new findings and revise their methodologies and designs in the very scope of their field. Language researcher’s personal commitments and presumptions and other issues of central importance will, definitely, influence future developments in research programs in applied linguistics and possibly result in fundamental changes in the way researchers in linguistics currently view their own work as well as research priorities in general. The research topics and approaches applied in the field of philosophy of research in applied linguistics, definitely, involve various philosophical and theoretical commitments, as well as methodological preferences and practices. In the present paper, alternative beliefs about the fundamental issues of the philosophy of research in applied linguistics and the central issues in research methodologies have been discussed.
