The Exploring Nature of Methodology in the Current Studies of Language Learning Strategies (LLSs) with Focus on Strategy Inventory for Language Learning (SILL) of Rebecca L. Oxford

Abstract

Several empirical studies have been found moderate intercorrelation between the items of six categories in SILL (Oxford & Ehrman, 1995). [...]Oxford (1996b) presents "each sub-scale would have an adequate number of items to facilitate more in-depth understanding of the learning strategies" (p.3). The sample for pilot study was selected so as it represents entire sample for participants whom asked to participate in main study. [...]sample size in pilot study ranges from 20 to bigger of 65(Hinkin, 1998). [...]as Dornyei (2003) points out advantages for self-report, as versatility, cost effectiveness, and efficiency in terms of staff and students time and effort. [...]most language research has favored the use of questionnaire, inventories, and survey because date can easily be collected by a large number of participants and analysis is uncomplicated (Cohen, 1998; Oxford, 1990, 1996b). Internal consistency and test-retest reliability are the most commonly used methods to check the reliability of tests and measures (Costa & McCare, 1992). [...]Cronbach Alpha, a measure of internal consistency, was chosen as the most appropriate reliability index" (Oxford, 1996a, p.31), and it is identified to be an appropriate measure which is applied in order to estimate the reliability of items within one instrument (Pedhazur & Schemelkin, 1991.
